A computer network shows how one or more computers are linked to each other to share resources. The main aim of a computer network is resource sharing, though there are other objectives related to computer networks. Computer networks can be classified by distance being traveled, topology, and communication equipment used. The popular types of networks based on geographical coverage include Local Area Network, Metropolitan Area Network, Wide Area Network, and Personal Area Network. Computer networks based on topology can either be a star, tree, or bus connection. Personal Area Network is the simplest type of computer network based on geographical coverage.
The typical span of a Personal Area Network is usually ten meters, though it can stretch above ten meters depending on signal strength. This network is called a PAN because it’s usually designed for an individual. In a PAN, two or more computers are connected either employing wired means or wireless. Numerous computers in a PAN can be connected using connecting cables, or a connection can be created using wireless means such as Wi-Fi and Bluetooth. A PAN can’t cover a width that is more than thirty feet. An example of a Personal Area Network is the connection between your phone and your computer or among numerous laptops.
For instance, you can allow your PC to share your mobile phone’s resources using a USB cable or Bluetooth. Types of Personal Area Networks include home, office networks, and the Body Area Network. The network configuration in offices or small buildings is a Local Area Network. LAN connects numerous computers in a building using cables such as coaxial cable or twisted pairs. The major benefit of using a Local Area Network is its transfer speed. Information is relayed between computers at a fast speed. Data security is also provided by this network connection as a third party can’t access your information.
WAN covers a large geographical location than MAN or WAN. It employs wireless technologies like Wi-Fi because it travels a longer distance. A wireless network like Bluetooth can’t be utilized in a WAN because of its poor signal strength. The type of connection employed in interstate networks is a Wide Area Network. WAN can span across numerous countries or even continents without being affected. A mobile phone’s network can be classified as a Wide Area Network as you can use it anywhere you find yourself. A MAN is a network that is employed in large geographical locations such as cities and metropolitans.
