Here we will discuss the term Computer Network and 6 types of computer network. So Let’s Begin with the definition of Computer network.
What is a Computer Network?
A computer network is a system of devices, including computers, servers, routers, and switches, that are connected together by communication channels for the purpose of sharing data and resources. Networks can be small, with only a few devices, or large, with thousands of devices.
The 6 Types of Computer Networks:
Chances are, if you’re reading this blog, you probably already know a thing or two about computer networks. But did you know that there are different types of computer networks? In this blog, we’re going to explore the 6 types of computer networks and how they work.
- LAN-Local Area Network
- WAN-Wide Area Network
- MAN-Metropolitan Area Network
- PAN-Personal Area Network
- WLAN-Wireless Local Area Network
- VPN -Virtual Private Network
What is a LAN-Local Area Network?
The most common type of computer network is the Local Area Network (LAN). A LAN is usually created using Ethernet cables and hubs or switches.
A LAN (Local Area Network) is a network that is confined to a relatively small area. Most LANs are limited to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves.
A LAN typically relies mostly on wired connections for increased speed and security, however, wireless connections are often used for convenience or in areas where wired connections are not possible or practical.
What is a WAN-Wide Area Network?
Another common type of computer network is the Wide Area Network (WAN). A WAN is a network that spans a large geographical area, like a city, country, or even the world. WANs are usually created using leased lines or wireless technologies.
A WAN is often used to connect smaller networks, such as local area networks (LANs) or metro area networks (MANs).
A WAN can be either public or private. A public WAN is usually owned and operated by a telecommunications company and is available for use by the general public. A private WAN is usually owned and operated by a business or other organization and is used to connect the different locations of that organization.
WANs can be either point-to-point or multipoint. In a point-to-point WAN, each connection between two sites is dedicated to that connection and is not shared with any other site.
In a multipoint WAN, multiple sites are connected to each other using a shared medium, such as a satellite link or a shared telephone line.
What is the MAN-Metropolitan Area Network?
A Metropolitan Area Network (MAN) is a network that spans a large geographical area, usually a city. A MAN usually consists of two or more Local Area Networks (LANs) that are connected together. A MAN is usually owned and operated by a single organization, such as a school, a business, or a government.
A MAN is usually much larger than a LAN, and it can span an entire city. A MAN can also be smaller than a LAN, and it can span a single building or a campus. A MAN can be as small as a single room, or it can be as large as an entire city.
A MAN can be used to connect two or more LANs together. This can be done using a variety of technologies, such as fiber optic cable, microwave, or satellite.
A MAN can also be used to connect two or more computers together. This can be done using a variety of technologies, such as dial-up, DSL, or cable.
What is a PAN-Personal Area Network?
A PAN, or personal area network, is a computer network organized around an individual person. The most common type of PAN is a wireless LAN (WLAN) connecting a mobile computer to peripherals such as printers and scanners.
Other types of PANs include Bluetooth networks, infrared networks, and wired USB networks.
A PAN typically has a range of about 10 meters (about 33 feet). The range of a Bluetooth network, for example, is about 10 meters (about 33 feet), while the range of an infrared network is only about 1 meter (about 3 feet).
Most PANs are designed to support a small number of devices. A Bluetooth network, for example, can support up to eight devices.
A PAN can be an extension of a larger network, such as a LAN or WAN. For example, a mobile computer with a PAN can connect to a LAN or WAN through a wireless access point.
What is a WLAN-Wireless Local Area Network?
A WLAN is a Wireless Local Area Network that uses radio waves to communicate wirelessly. A WLAN can be used to connect computers to each other, to the Internet, and to other types of devices such as printers and scanners.
WLANs use radio frequencies to communicate wirelessly. A WLAN can be used to connect computers to each other, to the Internet, and to other types of devices such as printers and scanners.
There are many benefits of WLAN, including the following:
- WLANs are very convenient because they allow users to connect to the network without having to use cables.
- WLANs are very flexible because they can be easily added to an existing network.
- WLANs are very cost-effective because they eliminate the need for expensive cables.
What is a VPN -Virtual Private Network?
If you’re looking to keep your online activity private, a Virtual Private Network (VPN) is a great way to do so. A VPN encrypts your internet traffic and routes it through a server in another location, masking your real IP address and location. This makes it difficult for anyone to track your online activity or identify your device.
There are a number of reasons you might want to use a VPN. Perhaps you want to prevent your ISP from tracking your online activity. Or you may be concerned about government surveillance or hackers snooping on your traffic. Whatever your reason, a VPN can help you protect your online privacy.
There are a number of VPN providers to choose from, and not all VPNs are created equal. When selecting a VPN, it’s important to consider factors such as speed, security, and price.
