When we think about the ideal place to live, one of the first things that comes to mind is safety. Whether we walk home late at night or simply leave our doors unlocked, feeling safe in our surroundings is an essential part of a happy life. So where in the world can we find the countries with the lowest crime rates? 

We're going to tour some of the safest countries on the planet, where crime is rare and citizens enjoy a calm, safe environment. These nations are not just places where crime is low; they are also examples of how the combination of strong government, social equality and community trust can be a haven of safety.

1. Iceland

Iceland is consistently ranked as one of the safest countries in the world. With a population of just over 366,000, this Scandinavian island is known for its low crime rates. Wild crime is almost non-existent and the overall crime rate is extremely low.

One reason for Iceland's safety is its strong sense of community. With a small population, people tend to know each other, which helps to build trust. In addition, Iceland has a highly educated population, a strong welfare system and effective law enforcement. The country's low levels of poverty and unemployment also help to create security.

Another interesting aspect of Iceland's security is the minimal police presence. The police force is small and police officers do not carry firearms, which reflects the peaceful nature of the country.

2. Japan

Japan is another country known for its extremely low crime rates. With more than 125 million people, it is one of the most densely populated countries, yet remains one of the safest.

Japan's safety can be attributed to several factors, including its strong cultural emphasis on respect, discipline and social harmony. From a young age, Japanese are taught the importance of adhering to social norms and respecting others. This cultural framework, combined with effective policing and a strong legal system, helps to maintain low crime rates.

In Japan, the crime that does occur is often minor, such as petty theft. Violent crimes are extremely rare and the country's homicide rate is one of the lowest in the world. In addition, Japan's well-managed infrastructure and public services, including efficient public transport, contribute to the overall sense of security.
 

3. Switzerland

Switzerland is famous for much more than its chocolate and stunning scenery, it is also one of the safest countries in the world. With a well-organised democracy, a strong economy and a high standard of living, Switzerland enjoys impressively low crime rates.

One of the key factors behind Switzerland's security is its strong social cohesion. The country has a long tradition of neutrality and places great emphasis on social responsibility. The Swiss are known for their respect for the law and for each other, which helps to maintain a peaceful society.

Switzerland's gun laws are unique in that many citizens own firearms due to mandatory military service, yet gun-related crime is very low. This paradox can be explained by the country's strict regulations regarding the use of firearms, intensive training and cultural attitudes towards violence.

4. Singapore

Singapore is often described as one of the safest cities and countries in the world. With a population of around 5.7 million people, Singapore has achieved an incredibly low crime rate thanks to strict laws and effective law enforcement.

The city-state is known for its zero-tolerance approach to crime, particularly with regard to drug offences and violent crimes. The legal system is strict and the penalties are severe, which acts as a strong deterrent. However, it is not only the fear of punishment that keeps crime rates low - Singaporeans also enjoy a high standard of living, excellent education and strong social services.

5. Norway

Rounding out the list is Norway, a Scandinavian country known for its stunning fjords and for being one of the safest places in the world. Norway's crime rate is low and its prison system focuses on rehabilitation rather than punishment, which has proven effective in reducing recidivism.

Norway's welfare system is among the best in the world, providing citizens with free health care, education and generous social benefits. This helps to reduce poverty and inequality, which in turn leads to lower crime rates. In addition, Norway's strong sense of community and trust in its state institutions contribute to its overall security.

Let’s take a look at some of the countries where people enjoy the highest purchasing power:

1. Switzerland

Switzerland often ranks at the top when it comes to purchasing power. Swiss citizens typically earn high wages, and even though the cost of living is also high, their income allows them to afford a wide array of goods and services. This means they can enjoy a comfortable lifestyle, with access to quality healthcare, education, and leisure activities. Plus, Switzerland’s stable economy and strong currency, the Swiss franc, play a big role in maintaining this high purchasing power.

2. Luxembourg

Luxembourg, a small but wealthy European country, also has one of the highest levels of purchasing power in the world. The country's economy is extremely strong, thanks in part to its status as a major financial centre. With a high average income and relatively low taxes, Luxembourg residents have substantial disposable income. Although housing can be expensive, overall purchasing power remains high, allowing for a very high standard of living.

3. United States

The United States is another country where purchasing power is particularly strong, although it varies widely between regions and cities. In places like New York or San Francisco, the cost of living is extremely high, which can reduce purchasing power. However, in many other parts of the country, especially in the Midwest or southern states, people can enjoy a high standard of living with relatively modest incomes. The different economic situation in the US makes it a unique case when discussing purchasing power.

4. Germany

Germany is Europe's largest economy and also has one of the highest levels of purchasing power on the European continent. With a strong manufacturing base, high wages and a relatively modest cost of living, Germans enjoy a good balance between income and expenditure. The country's welfare system also supports this, ensuring that even those on lower incomes can afford basic necessities.

5. Australia

Australian residents also benefit from high purchasing power. Australia's strong economy, which is based on natural resources, tourism and finance, offers good wages and a high standard of living. While some cities such as Sydney and Melbourne are very expensive, overall purchasing power remains high, particularly in more rural areas.

Data Transmission via Copper:

Operation

Copper cables are used to transmit data through electrical signals. These signals propagate along the cables, carrying information from one point to another. Copper is an excellent conductor, allowing signals to travel at relatively high speeds. However, transmission performance can be affected by distance and external interference, such as electromagnetic radiation from other devices.

Data Transmission via Optical Fibers:

Operation

Optical fibers transmit data using light signals. Light travels through the fibers by continuous reflections, maintaining signal quality unaffected by external interference. This property allows optical fibers to offer high transmission speeds and long-distance transmission without losses.

Performance Comparison

Speed

• Copper: Data transmission speed via copper is limited, especially over long distances. DSL connections can offer speeds up to 100 Mbps, but actual speeds may be lower due to interference and distance from the central switch.

• Optical Fibers: Optical fibers support speeds reaching and exceeding 1 Gbps, making them ideal for demanding applications like 4K video streaming and online gaming. Speed remains stable regardless of distance.

Reliability and Stability

• Copper: The reliability of copper connections can be affected by interference and external factors such as weather conditions. The quality of the cable and connections also plays a role in connection stability.

• Optical Fibers: Optical fibers are highly reliable as they are unaffected by electromagnetic interference. This ensures a stable connection even in environments with high noise levels.

Transmission Distance

• Copper: The performance of copper cables decreases with distance. Over long distances, signal quality degrades, requiring amplifiers to maintain the connection.

• Optical Fibers: Optical fibers can transmit data over much longer distances without losses, making them ideal for long-distance networks, such as international communication cables.

Advantages and Disadvantages

Copper

Advantages:

• Lower initial cost.
• Wide availability and familiar technicians.
• Satisfactory performance over short distances.

Disadvantages:

• Limited speed and transmission distance.
• Sensitivity to interference.
• Higher maintenance requirements.

Optical Fibers

Advantages:

• Very high transmission speeds.
• Great reliability and stability.
• Ability to transmit over long distances without losses.

Disadvantages:

• Higher initial material and installation cost.
• Requires specialized equipment and technical knowledge for installation.

Conclusion

The choice between copper and optical fibers depends on the user’s needs and budget. While copper remains an affordable and easy solution, optical fibers offer superior performance and reliability, making them the best choice for those seeking high speeds and stability. Personally, I prefer optical fibers for their unparalleled quality and future potential.

Get ready to enter the world of Instagram with confidence and learn the secrets to a successful acquaintance!

Understanding Instagram

Before you start your adventure on Instagram, it's important to understand how this platform works. It's not just about selfies and food – Instagram is a multifaceted space with a variety of opportunities for social networking and personal marketing.

The Alphabet of Instagram

Photos and Stories: The main feature of Instagram is photos. However, don't limit yourself to these alone. Use stories to show more spontaneous moments.

Hashtags and Geotags: Use hashtags and locations to increase your visibility. This helps you reach a broader audience interested in similar topics.

Followers: The number of people you follow and those who follow you plays a role in how others see you. Follow people you like and connect with the community.

How to Stand Out

Uniqueness: Showcase your uniqueness. Be authentic and share things that truly represent you.

Dialogue: It's important to create dialogue. Respond to comments, ask questions in captions, and show interest in others' views.

Understanding User Psychology

Empathy: See beyond the photos. Every person has their own story and concerns.

Emotional Intelligence: By adapting your behavior based on how someone responds, you can build deeper relationships.

Instagram is not just a platform; it's a world filled with people and stories. With the right understanding and approach, you can discover unique opportunities to connect with someone who interests you.

Creating an Attractive Profile

Your Instagram profile is like your digital identity. It's the first thing others will see and gives them a quick picture of you. Therefore, creating an attractive and interesting profile is crucial.

Quality Photos

Personality: Choose photos that show your personality and interests. Don't be afraid to show your true self.

Quality: Use clear, high-quality images. This shows that you pay attention to details.

A Well-Crafted Bio

Information about you: Your bio should be brief but powerful. Talk a little about yourself and what makes you unique.

A well-structured profile is like an open door. It invites others to come in and get to know the real you. In this way, you're not just sharing an image, but a whole story.

Finding the Right Audience

When it comes to meeting a girl on Instagram, it's important to find the right audience. This means you should follow and interact with people who share interests with you.

How to Interact

Comments and Likes: By leaving comments and liking posts, you show interest and approach. Try to make comments that are personal and genuine.

Messages: If you want to advance the acquaintance, you can send a private message. Make sure the message is friendly, respectful, and open.

Safety and Respect

Personal Boundaries: Respect the other person's boundaries. If they do not respond to your message or show interest, do not insist.

Authenticity: Approach with authenticity and honesty. Don't pretend to be something you're not just to gain someone's attention.

By finding the right audience and interacting with respect and interest, you increase your chances of meeting someone who shares your interests and appreciates you for who you truly are.

Communication and Interaction

After you have found the right audience and invested in your profile, the next step is communication and interaction. This can be the most interesting but also the most challenging part of the process.

How to Start a Conversation

Opening: Start with something interesting but simple. An observation about something you saw in her profile or a light question can be ideal.

Naturalness: Try to be natural and avoid cliché phrases or forced jokes. Authenticity is key.

Creating Interest

Common Points: Look for common interests and topics of discussion. This can help you create a more substantial conversation.

Topic Changes: Avoid dwelling on one topic. Changing topics and the pace of the conversation creates a more dynamic discussion.

Maintaining Attention

Interest and Listening: It's important to show interest in her responses and views. Be attentive and show that you really listen.

Personal Space: Do not pressure for personal information or meetings if she does not seem ready or comfortable with it.

Communication on Instagram can be as interesting as it is complex. But with the right approach and respect for the other side, you can make the conversation stand out and be memorable.

Managing Online Acquaintances

Managing online acquaintances is a critical area that requires sensitivity, maturity, and understanding. When it comes to acquaintances on Instagram, there are some basic principles to consider.

Managing Expectations

Realistic Expectations: It's important to have realistic expectations. Not all conversations will lead to a deeper acquaintance or relationship.

Respect for Time: Understand that some people may not be interested or may not have the time to respond immediately. Respecting their time is fundamental.

Online Safety

Personal Details: Be careful with how much personal information you share. Keeping some details private is important for your safety.

Identity Verification: In an era where fake accounts are common, it's important to verify the identity of the person before proceeding to deeper communication.

Building Trust

Honesty: Honesty is essential for building trust. Be genuine in your intentions and words.

Mutual Communication: A healthy relationship is based on mutual communication. Be ready to listen and openly share thoughts and feelings.

By managing expectations, ensuring online safety, and building trust, you can make online acquaintances more satisfying and evolve a relationship to a more mature level.

Conclusion and Communication Beyond Instagram

After a positive exchange of messages on Instagram, you may reach a point where you feel ready to take your acquaintance to the next level. Transitioning from online to the real world is a significant step and should be done with respect and understanding.

Proposing Communication Beyond Instagram

Natural Transition: When the conversation flows smoothly and there seems to be mutual interest, you can suggest switching to a different means of communication such as phone, or even a meeting.

Respect for Boundaries: Offer options and be ready to accept a 'no'. Respecting boundaries is vital.

Communication Beyond Instagram

Phone/Email Communication: Communication via phone or email can add a more personal dimension to your acquaintance.

Personal Meetings: If both sides are comfortable, a personal meeting can be the next step. Choose a public and safe place for the first meeting.

The transition from Instagram to more personal forms of communication requires sensitivity and understanding. With the right approach and respect, you can build an even more significant relationship.

Conclusion

Meeting a girl on Instagram can be an interesting and enjoyable process, but it requires respect, authenticity, and open communication. Through creating an attractive profile, discovering the right audience, communicating, and managing online acquaintances, you have the potential to create a rich and significant dialogue.

Remember that the best acquaintance is one based on honesty and mutual respect. Trust and true connection develop over time, and patience is key in this process.

In closing, Instagram is a powerful platform that offers unique opportunities for acquaintances and relationships. When used with respect and genuineness, it can be a gateway to significant human connections and new experiences.

As we have written many times above, be careful and respectful towards the girl. 'No' means no, and we do not insist or pressure situations.

Good luck!

I'm sure you've heard a computer technician tell you, format your computer, and it will be as good as new. A friend or acquaintance will have told you that your computer needs a Format, to make it like new. So let's go over what a Format is, and how you can do it yourself without having to go to a technician and pay a pretty hefty sum of money.

What is Format?

Format is the formatting of a partition or the entire disc. In the simplest terms and as we call it in the village, Format is the permanent deletion of all files from the computer and reinstallation of the operating system. At this point and before we proceed to Format, it is advisable to keep a backup of all the files and programs we need. After the Format all files and programs will have been permanently deleted. Let's get started doing the Format.

Step 1

First we find the My Computer icon (usually on the desktop).

Then we right click and find the properties option, and from there we see what architecture our Pc is on. Once we have found the architecture of our PC (32 or 64 bit) we continue with step 2.

Step 2

We go to the Microsoft page to download the file we will need to do the Format. I am adding the link for your convenience https://www.microsoft.com/el-gr/software-download/windows10ISO

From the options that Microsoft will show you don't forget to select the correct computer architecture as we saw in step 1.

Step 3

Once you have downloaded the file, run it.

It will bring up 2 options at first. We will choose the 2nd one where it says create installation media for another PC.

We click next and then select language, version and architecture.

And finally and very importantly it will ask us to choose the flash drive where we will install the operating system. Attention here we choose the first option which says USB flash drive. Make sure we have a flash drive of at least 8GB and have it connected to our computer. We press Next.

Step 4

After we have installed the Installation on our flash drive, we reboot our computer.

Here, as soon as the computer opens, we will need to hold down one of the following keys .ESC,F8,F9,F10,F11,F12 Depending on the motherboard we have. Attention each motherboard has its own key to show us the BIOS Menu. Which key we will need to press is usually written down as soon as the computer opens.

Having entered the BIOS MENU we find the BOOT tab

We then choose to have our computer start reading the USB flash drive rather than the hard drive.

After we have selected the media our computer will BOOT to, we press F10 to save our choices.

Step 5

We will be presented with a Windows 10 Setup window. Select the language you want and click Next

The next step will ask us to enter the activation code. Press Skip

Then we accept all the terms.

After we have done all the above actions correctly, we go to the most important step. It will show us 2 options. We to do formatting we will choose the 2nd option where it says Custom Install Windows only.

Next action we will need to do is to delete all the data from the hard drive partitions. We select the partitions one by one and press Delete.

Once we have deleted all the partitions. We will select the hard drive where we want to install Windows 10, and click Next.

That's it, now Windows will do the installation on its own and we'll have to wait a few minutes for it to complete.

Step 6

Now all that remains is to configure Windows as we want. E.g. give it a username, set a password, etc.

ATTENTION!!!! Don't forget after installing Windows 10 to go to BIOS MENU and again select the Hard Disk as the boot media.

You just formatted your computer.

What is WPA3 ?

WPA3 (Wi-Fi Protected Access III) is the latest security standard for wireless networks, developed by the Wi-Fi Alliance. It was introduced as a replacement for WPA2 to address the security weaknesses that were discovered in WPA2. WPA3 provides stronger security by using the latest encryption algorithms, such as Advanced Encryption Standard (AES) in Galois/Counter Mode (GCM) and Elliptic Curve Diffie-Hellman (ECDH) for secure key exchange.

WPA3 also introduces two new security features:

• Simultaneous Authentication of Equals (SAE) for improved protection against offline dictionary attacks.
• Opportunistic Wireless Encryption (OWE) for improved protection against eavesdropping.

WPA3 is backward compatible with WPA2, so devices that support WPA3 can connect to networks that are still using WPA2, but the connection will be made at the lower WPA2 security level.

WPA3 vs WPA2

WPA3 (Wi-Fi Protected Access III) is the latest security standard for wireless networks, and it's developed by the Wi-Fi Alliance as a replacement for WPA2.

WPA2 (Wi-Fi Protected Access II) is the previous security standard for wireless networks, it was introduced in 2004 and it's widely used.

The main differences between WPA3 and WPA2 are:

• Encryption: WPA3 uses the latest encryption algorithms, such as Advanced Encryption Standard (AES) in Galois/Counter Mode (GCM) and Elliptic Curve Diffie-Hellman (ECDH) for secure key exchange, while WPA2 uses AES in Counter Mode with CBC-MAC (CCM) for encryption and Temporal Key Integrity Protocol (TKIP) or AES-based CCMP for integrity.

• Security Features: WPA3 introduces two new security features:

  • Simultaneous Authentication of Equals (SAE) for improved protection against offline dictionary attacks.
  • Opportunistic Wireless Encryption (OWE) for improved protection against eavesdropping.

• Backward compatibility: WPA3 is backward-compatible with WPA2, meaning that devices that support WPA3 can connect to networks that are still using WPA2, but the connection will be made at the lower WPA2 security level.

In summary, WPA3 provides stronger security by using the latest encryption algorithms and introducing new security features. It is recommended to use WPA3 if possible, but WPA2 is still considered to be secure and can be used if WPA3 is not supported.

Simultaneous Authentication of Equals (SAE)

Simultaneous Authentication of Equals (SAE) is a feature of the WPA3 security standard for wireless networks. It is designed to improve the security of wireless networks by providing protection against offline dictionary attacks.

Traditionally, wireless networks use a shared key (or password) to authenticate devices that are trying to connect to the network. This shared key is used to encrypt the data being transmitted over the network, but it can also be used to authenticate devices that are trying to connect. However, if an attacker can obtain the shared key, they can use it to authenticate themselves and gain access to the network.

SAE is a new authentication mechanism that uses a different approach. Instead of using a shared key, SAE uses a cryptographic key exchange algorithm to establish a unique session key between the client and the access point. This session key is used to encrypt the data being transmitted over the network. The key exchange process is designed to be resistant to offline dictionary attacks, which means that an attacker cannot simply try a large number of potential shared keys in order to gain access to the network.

In summary, SAE is a more secure method for wireless authentication that is resistant to offline dictionary attack, and it's one of the key features of WPA3 standard.

Opportunistic Wireless Encryption (OWE)

Opportunistic Wireless Encryption (OWE) is a feature of the WPA3 security standard for wireless networks. It is designed to improve the security of wireless networks by providing protection against eavesdropping.

OWE aims to improve the security of open wireless networks, which are networks that do not use any form of encryption. OWE allows a device to encrypt its wireless communications automatically even when connecting to an open network. By doing so, it makes it more difficult for an attacker to intercept and read the communications of other devices connected to the network.

OWE works by using a Diffie-Hellman key exchange algorithm to establish a unique session key between the client and the access point. This session key is used to encrypt the data being transmitted over the network.

In summary, OWE is a way to add encryption to open wireless networks, this makes it more difficult for an attacker to intercept and read the communications of other devices connected to the network. And it's one of the key features of WPA3 standard.

Advanced Encryption Standard (AES)

Advanced Encryption Standard (AES) is a widely used symmetric encryption algorithm that is considered to be highly secure. It was developed by the U.S. National Institute of Standards and Technology (NIST) and is specified in the Federal Information Processing Standards (FIPS) publication 197. It is used to encrypt sensitive data such as credit card numbers, personal information, and government classified information.

AES uses a fixed block size of 128 bits and supports key sizes of 128, 192, or 256 bits. It operates on a fixed number of rounds, determined by the key size, and uses a complex substitution-permutation network (SPN) structure to encrypt and decrypt data.

AES can be used in different modes of operation such as Electronic Code Book (ECB), Cipher Block Chaining (CBC), Counter (CTR), and Output Feedback (OFB). ECB is the simplest mode, but it has known security weaknesses, for this reason, other modes like CBC and CTR are recommended.

AES is widely supported and implemented in hardware and software, it is used in many applications and protocols such as VPNs, disk encryption software, and Wi-Fi security (WPA3). It is considered to be a robust encryption standard that has stood the test of time and is considered to be highly secure.

Wi-Fi 6 is the latest version of the Wi-Fi standard for wireless local area networks (WLANs). It is also known as 802.11ax, and it is designed to provide faster speeds, greater capacity, and improved performance in dense wireless environments.

Wi-Fi 6 uses a number of new technologies to achieve these goals, including Orthogonal Frequency-Division Multiple Access (OFDMA), Multi-User Multiple Input, Multiple Output (MU-MIMO), and Target Wake Time (TWT). Additionally, Wi-Fi 6 is also more energy-efficient than previous versions, which can help to extend battery life for devices that use it.

Positive aspects of Wi-Fi 6 include:

Faster speeds: Wi-Fi 6 is capable of delivering faster speeds than previous versions, which can be beneficial for activities such as streaming video or playing online games.
Greater capacity: Wi-Fi 6 can handle more devices and traffic than previous versions, which can be beneficial in crowded wireless environments such as airports or stadiums.
Improved performance in dense wireless environments: Wi-Fi 6 uses technologies such as OFDMA and MU-MIMO to improve performance in environments where there are many devices competing for the same wireless spectrum.
More energy-efficient: Wi-Fi 6 is designed to be more energy-efficient than previous versions, which can help to extend battery life for devices that use it.

Negative aspects of Wi-Fi 6 include:

Requires new hardware: To take advantage of Wi-Fi 6, both the wireless router and the devices connecting to it must support the new standard.
Not fully adopted yet: Wi-Fi 6 is a relatively new standard and not all devices and routers currently support it, so you may have to wait for newer devices to be able to fully take advantage of Wi-Fi 6.
Higher costs: Wi-Fi 6 routers and devices tend to be more expensive than those that support older versions of the Wi-Fi standard.
It's worth mentioning that many of the negative aspects will be addressed as the adoption and availability increase and the prices decrease over time.

What is OFDMA

Orthogonal Frequency-Division Multiple Access (OFDMA) is a multiple access technique used in wireless communication systems, such as Wi-Fi 6. It is a type of multi-user version of the popular orthogonal frequency-division multiplexing (OFDM) digital modulation scheme.

In OFDMA, a single channel is divided into multiple subchannels, each with a narrow band of frequencies. These subchannels can then be assigned to different devices, allowing them to communicate simultaneously over the same channel. This is in contrast to traditional multiple access schemes such as Time Division Multiple Access (TDMA), where devices take turns using the channel.

OFDMA can improve the capacity and efficiency of wireless networks by allowing multiple devices to share the same channel simultaneously. It also allows for better management of wireless resources, and it can help to reduce interference between devices.

OFDMA is used in Wi-Fi 6 to increase the number of devices that can be connected to a network at the same time, and also to improve the performance of the network in crowded wireless environments.

What is TWT

Target Wake Time (TWT) is a feature of Wi-Fi 6 (802.11ax) that helps to reduce power consumption on devices that use the standard. TWT allows devices to schedule their wake times so that they can conserve power when not in use.

With TWT, a device can negotiate a schedule with the access point (AP) for when it will wake up to receive data. The device can then enter a power-saving mode when it is not scheduled to wake up, which can help to extend its battery life. The device will then wake up only at the scheduled time to check for new data and then return to power-saving mode.

TWT is particularly useful for IoT devices and other devices that are battery-powered and have low-bandwidth requirements. TWT can be used in conjunction with other Wi-Fi 6 features, such as OFDMA, to further improve the energy efficiency of the network.

It's important to note that TWT support is not required for devices or APs to be Wi-Fi 6 certified, but it can be used as an optional feature to improve energy efficiency.

A few words about WPA3

WPA3 (Wi-Fi Protected Access III) is the latest security standard for wireless networks, developed by the Wi-Fi Alliance. It was introduced as a replacement for WPA2 to address the security weaknesses that were discovered in WPA2. WPA3 provides stronger security by using the latest encryption algorithms, such as Advanced Encryption Standard (AES) in Galois/Counter Mode (GCM) and Elliptic Curve Diffie-Hellman (ECDH) for secure key exchange.

WPA3 also introduces two new security features:

• Simultaneous Authentication of Equals (SAE) for improved protection against offline dictionary attacks.
• Opportunistic Wireless Encryption (OWE) for improved protection against eavesdropping.

WPA3 is backward compatible with WPA2, so devices that support WPA3 can connect to networks that are still using WPA2, but the connection will be made at the lower WPA2 security level.
