explain different types of computer networks. fast please tomorrow is my exam
Answers
〠 Personal area network
A personal area network or PAN, is a computer network organized around an individual person within a single building.
〠 Local area network
A local area network , or LAN consists of a computer network at a single site, typically an individual office building.
〠 Metropolitan area network
A metropolitan area network, or MAN, consists of a computer network across an entire city, college campus or small region
〠 Wide Area Network
A wide area network, or WAN, occupies a very large area, such as an entire country or the entire world.
〠 Private area network
One of the benefits of networks like PAN and LAN is that they can be kept entirely private by restricting some communications to the connections within the network. This means that those communications never go .
〠 Campus area network
Larger than LANs, but smaller than metropolitan area networks (MANs, explained below), these types of networks are typically seen in universities, large K-12 school districts or small businesses

A computer network can be categorized based on geographical location and characteristic. Based on geographical location, computer networks are outlined below.
LAN (Local Area Network) - A LAN is a computer network which spans over a small geographical area such as home, building, office, etc. In LAN, computers are placed relatively close. Since computers are located within small distance, they do not need special devices and cables to connect with each other.
MAN (Metropolitan area networks) - A MAN is a computer network which connects two or more LAN networks within same city. When due to distance connecting two LANs is not possible, MAN network is used. It is larger than LAN but smaller than WAN. It deploys special devices and cables to connect the LANs.
WAN (Wide Area Network)
WAN is a computer network which spans over a large geographical area such as state, region, country etc. WANs are typically used to connect two or more LANs or MANs which are located relatively very far from each other. To provide connectivity, this network uses special devices, cables and technologies.
PAN (Pearson Area Network)
Same as LAN network, but it is limited to a specific person or location such as home network. This network is usually setup for sharing resources such as internet and printer within personal computers.
CAN (Campus Area Network)
Same as MAN network, but it is limited to a university or an academy. This network is usually setup for educational activities such as classroom updates, practices labs, emails, exams, notifications, polls, etc.
GAN (Global Area Networks)
Same as WAN network, but it covers unlimited geographical area. For example a company has an office in Delhi and another one Washington D.C., connecting these two offices will be considered as a GAN network. In other words, GAN is a computer network which connects two or more WANs. This network is increasingly gaining popularity as many companies are expending their working area beyond their native countries.
