Computers are becoming an integral part of our lives, not just in the office but also at home too. With the current trend of digitally dependent society, it is important that we stay updated about the latest technology advances and how they can benefit us.
A wired network is a computer network that uses wired connections to connect devices. Wired networks can use either cables or fiber optics to connect devices. Cables are the most common type of connection for wired networks. They are easy to install and are relatively inexpensive. Fiber optics are less common, but they offer a higher bandwidth than cables.
A wireless network is a type of computer network that uses radio waves to communicate between devices. Wireless networks can be used to connect computers, printers, and other devices to each other and to the Internet. Wireless networks are convenient because they do not require cables or other physical connections between devices.
Wireless networks have become increasingly popular in recent years as more and more devices are able to connect to the Internet wirelessly. Many laptops, smartphones, and other portable devices are equipped with wireless networking capabilities, so users can stay connected while on the go. Wireless networks can also be used in homes and businesses to provide Wi-Fi access for devices such as laptops, tablets, and smartphones.
A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall can be hardware- or software-based, and it is often used in conjunction with other security measures, such as antivirus software and encryption.
An intranet network is a type of computer network that allows for communication and data exchange between computers within an organization. This type of network is usually private, and only accessible to authorized users. Intranets can be used to share internal company information, such as employee directories and contact information, as well as provide access to shared resources, such as file servers and printers.
An extranet network is a computer network that is accessible by authorized outsiders. The term is most often used in reference to networks used by organizations, businesses, and other groups.
Extranet networks differ from the more commonly known intranet in that they are not limited to members of a single organization. Instead, an extranet can be made up of multiple organizations or individuals who have been granted access to the network.
One common use for an extranet is to allow business partners access to shared information and applications. For example, two companies who frequently do business together might set up an extranet so that their employees can easily share documents and data.
Another common use for an extranet is to give customers or clients limited access to a company’s internal systems. For example, a bank might set up an extranet that its customers could use to check account balances or transfer money between accounts.
Extranets can be useful for many different purposes, but they all have one thing in common: they allow people who are not part of a single organization to interact and share information with each other over a computer network.
A private network is a computer network that uses private IP address space. The most common type of private network is a home network. A home network usually consists of a router, which connects to the Internet, and a number of computers and other devices, which are connected to the router.
A private network can also be a corporate network. A corporate network is usually much larger than a home network and includes many more computers and devices. The computers and devices on a corporate network are often located in different parts of the world.
Virtual Private Network (VPN)
A VPN is a private network that uses public infrastructure, such as the Internet, to provide secure and encrypted connections for remote users or sites. VPNs are often used by businesses to allow employees to securely connect to their company network from outside the office. They can also be used to securely connect to public Wi-Fi hotspots.
VPNs use a variety of security protocols, or rules, to encrypt data transmissions and protect user privacy. The most common protocols are PPTP, L2TP/IPSec, SSTP, and IKEv2/IPSec. VPNs can also be configured to use other less common protocols, such as OpenVPN and Wire Guard.
Local Area Network (LAN)
A LAN is a computer network that connects devices in a small area, such as a home, office, or school. LANs use Ethernet or Wi-Fi technology to connect devices over short distances. Most LANs are designed to support only a limited number of devices and offer little or no Internet access.
Wide Area Network (WAN)
A WAN is a computer network that spans large geographical areas, such as countries or regions. WANs typically use high-speed leased lines or public broadband Internet connections to connect devices over long distances. Many WANs are designed to support thousands of devices and offer unlimited Internet access.
There are a variety of different types of computer networks that you can have in your home or office. The type of network you choose will depend on your specific needs and requirements. We hope that this article has helped you understand the different types of computer networks that are available and how to choose the right one for your needs.
