VPN is an abbreviation for “Virtual Private Network” or “Virtual Private Network” in English. VPN is an information security technology that allows users to connect through the Internet and communicate securely and privately with each other. The VPN uses an encrypted tunnel between the user’s device and the VPN server, hiding the user’s activity on the Internet and making it difficult for hackers, authorities, and anyone tracking it. VPN users can access the Internet from different countries and countries and have different IPs. VPNs can be used for various purposes, such as internet information security or access to restricted services and sites that censor information. However, it is essential to understand that a VPN is not an absolute solution to protect personal data online and that some risks must be considered.
Your device’s internet connection is run through your VPN’s private server instead of the ISP, the internet service provider. This means that when your data is transferred to the Internet, it comes from the VPN. A VPN acts as an intermediary to help you connect to the Internet, consequently hiding your IP address and protecting your identity online. A VPN creates a secure and private space from the device you use on the Internet to keep your essential data private.
There are several reasons why you should use a VPN: Internet Security: Using a VPN can help protect your data and your online activity from those tracking or “spying” on your online activity. Using VPNs, your data transmitted over the internet will be encrypted and hidden by external parties. Internet access in censored countries: In some countries, internet access is restricted, and some sites are blocked. VPNs can help access these sites and services, making them possible for users there. Privacy Protection: In some cases, devices and apps may track your online activity and collect personal data. Using a VPN can help protect privacy by hiding your IP and making it difficult for them to track your online activity. Secure public Internet browsing: Using the public Internet, such as open Wi-Fi networks in squares, stations, airports, train stations, hospitals, schools, etc. There is a risk of “hacking” your information. Using the VPN helps protect your information from possible hacking and other security breach attacks. However, it is essential to understand that using VPNs is not an absolute solution to protect personal data online and that some limitations and risks must be considered.
Wi-Fi 6 (or 802.11ax) is a new standard of wireless network technology that offers high data transfer speeds and significantly changes previous Wi-Fi standards. This technology provides a higher data transfer speed, reaching up to 9.6 Gbps/sec (gigabit per second) compared to the 3.5 Gbps/sec that the previous Wi-Fi 5 standard (802.11ac) offers. You can stream video and send data faster over the Wi-Fi network. Wi-Fi 6 has other features that make it more efficient and secure. One of the main changes is that it uses OFDMA (Orthogonal Frequency-Division Multiple Access) technology, which allows more devices to connect to wi-fi networks and use separate channels for data transmission. This means that even if many devices use wi-fi networks, they do not affect the network performance and service of one device from the other connected to Wi-Fi. Also, Wi-Fi 6 uses MU-MIMO (Multi-User Multiple-Input Multiple-Output) technology, which helps increase network speed and allows equipment to use separate channels. Under previous Wi-Fi standards, devices could connect to a channel, while with Wi-Fi 6, some devices can use separate channels at the same time. In general, Wi-Fi 6 is a higher-standard wireless network technology that offers higher speeds. These changes make it more efficient and secure, allowing more devices to connect to wi-fi simultaneously.
A proxy server acts as a mediator between clients and other servers on the Internet. Instead of requesting and receiving data directly from the desired server, customers connected to a proxy server send their requests for data through this server. The proxy server intermediates requests and receives data from the desired server, returning the response to the client. There are several reasons why a proxy server is being used. One of the main reasons for this is security, as using a proxy server can help protect the user’s identity and personal data. The proxy server can mask the user’s IP address and hide its activity on the Internet. Another reason to use the proxy server is to increase internet access speed. The proxy server may store copies of the web page and other data in its memory, allowing users to request and receive data faster if their requests are addressed to that server. Similarly, a proxy server can be used to restrict internet access, limiting users’ access to certain web pages. A proxy server can also distribute network load across several servers, allowing a more stable and fast service for users.
A proxy server creates its IP address. When you request access to a site from an internet server, rather than sending that request directly, your proxy server “bugs” it and asks for it for you. Then, you expect the webserver to handle that request and provide the desired data. After that, it collects and sends this data to your computer, allowing you to load the required website. The critical part of this process is that the proxy server can change your request. This includes providing the web server with a different IP address so it does not know where the request originated. It can also encrypt the data you send, ensuring an external source does not read it until it reaches the web server.
Using a proxy server brings several benefits to users on the internet, both in terms of security, performance, and control of internet access. The following are some of the main benefits of the use of a proxy server: Security and Privacy: A proxy server can protect the user’s identity and personal data by hiding its IP address and masking its internet activity from the desired server. This makes it harder for hackers and cybercriminals to steal users’ data. Access restriction: A proxy server can restrict internet access, allowing users to access only certain websites and limiting potentially dangerous ones. This helps protect users from viruses, malware, and those searching for personal data. Performance: Using a proxy server can improve internet access performance by storing copies of websites and other data in its memory. This allows users to search and retrieve this data faster if their requests are addressed to this server. Band restriction: A proxy server can restrict internet access, restrict user data access to specific sites, or allow only access to specific web pages. This helps control the use of internet broadband and can help prevent the usage of internet broadband by apps and other internet services. Network load distribution: A proxy server can distribute network load across several servers, allowing users a more stable and rapid service. This can help avoid service disruption if a server is occupied or malfunctioning.
A local area network (LAN) is a small network of computers and other electronic devices connected in a limited physical space, such as an office, house, or small building. In this network, devices are connected via a cable infrastructure or without cables, such as Ethernet, WiFi, Bluetooth, etc. In a LAN, devices can share and access various sources, such as printers, files, and internet connections, and communicate without using the Internet. LAN can be externally protected using firewalls and other security tools to stop illegal access to the local network. A LAN is often used in business environments, educational institutions, university campuses, or even at home when two or more computers are connected to a network to share resources and information. The WAN is a network that connects many devices in a wide range, such as cities, states, and even countries worldwide.
Lan (Local Area Network) has many advantages, including: Allocation of resources: In a LAN, devices can share resources as diverse as printers, files, and other services, improving the efficiency and productivity of the work. Direct connections between devices in a LAN are much faster and more secure than connections via the Internet. This can help communicate more effectively between members of an organization or a family when working with equipment part of this Lani. Less cost: LAN is cheaper to install and maintain, mainly if the devices are located in the same place. Higher security: In a LAN, the administrator can deploy security measures, including firewalls and other security tools, to protect the network from unauthorized inputs. Easier access: In LAN, it is easier to access various sources of network equipment, including printers, files, and other computers. This can make work more efficient and help increase labor productivity.

Creates opportunities for data flow

Sharing data between connected devices in Lan is a great practical benefit, but it can have a piracy attack breaching the central area to hack your entire Lanin, i.e., the equipment that is part of it. To avoid this, you need to make sure that the security measures are effective and maintained on time.
Geographical limitations
Information can usually not be shared outside the building. This means users must be near the central area of Lan to access resources.

Collisions affect everyone involved 

Because every connected computer and device accesses data from the same central point, the smallest problem can affect all computers’ devices. To avoid major problems, make sure you are doing regular maintenance.

WAN is the acronym for “Wide Area Network,” which means a wide array of appliances over large distances. WAN is a network that connects two or more LANs or other network constructions and devices located at long distances, including distances within one state or several states. In contrast to LAN, which connects devices within a limited physical area, WAN makes it possible to connect devices through various infrastructures, such as telecommunications lines, satellites, cellular networks, etc. WAN is used for internet access and for connecting operators everywhere in the world. For example, a corporation with offices in different countries of the world can use WAN to connect all its offices in a single network. This is how data and services are shared between them, making cooperation and communication between offices more efficient. WAN can also be used to connect data centers, government centers, organizations, economic groups, companies, and universities with several sites, etc.
Here are some advantages of the WAN network: Long-distance connections: WAN enables perfect connections between devices located at long distances. This makes it possible to communicate and collaborate between organizations and individuals in different countries. Access to multiple sources: With WAN, an organization can have access to different sources in different countries of the world. Data sharing between devices: WAN enables data sharing between devices at different distances. This enables the exchange of data and cooperation between individuals and organizations located in different countries of the world in different offices of this network. Efficiency: WAN can serve multiple users at the same time, enabling them to access the organization’s data and services. Flexibility: The WAN may vary depending on the organization’s needs. This makes adapting the WAN network to meet the organization’s specific needs possible. Security: WAN can provide a high degree of protection for data and services located on the network. This is important for organizations that must protect their data from attacks and security threats. These advantages make WANs suitable for organizations operating at the inter-level, between near or far-off countries.
Cost: WAN networks can be so extensive that setting up and maintaining a quick connection between locations can be costly. Maintenance also requires continuous supervision because any unresolved defect or problem can affect multiple business addresses and disrupt all equipment, leaving some offices or persons without work. Security: While transferring information through a WAN provides privacy, operating at multiple locations means there is a risk of data being intercepted by hackers. To improve employee and customer data security, measures are taken to make the network unsafe through the WAN crypto. Speed: Information is distributed over a large geographic area, with many devices sharing access to the same central infrastructure, which can affect speed. A WAN accelerator, which “compresses” data and reduces delay, can address this.
