How is PAN different from WAN? Explain with diagram.
Answers
Answer:
Personal Area Network (PAN)
PAN stands for personal area network, and again, it's exactly what it sounds like: a network covering a very small area, usually a small room. The best known wireless PAN network technology is Bluetooth, and the most popular wired PAN is USB. You might not think of your wireless headset, your printer or your smartphones as components in a network, but they are definitely talking with each other. Many peripheral devices are actually computers in their own right. Wi-Fi also serves as a PAN technology, since Wi-Fi is also used over a small area.
WAN
WAN (Wide Area Network), in contrast to a LAN, refers to a wide area network. The name is exactly what it sounds like: a network that covers an area wider than a LAN. Beyond that, the definition is less clear. Distances can range from a network connecting multiple buildings on a corporate or college campus to satellite links connecting offices in different countries. The most popular WAN is the one you're using to read this article: the Internet. It's actually a collection of other networks, including other LANs and WANs - hence, the name.
WANs can be wired, using fiber-optic cable, for example, or wireless. A wireless WAN might use microwave or infrared (IR) transmission technology, or even satellite. Laying fiber may make sense when connecting a campus but becomes more expensive when connecting greater distances. To save money, an organization may opt for wireless technology or lease lines from a third party.
Answer:
Pan-It exists in limited are network for professional use such as house.A network is two or more computers connected together in a way that allows them to share resources. ... These are Personal Area Networks (PANs),
Wan-Whereas is used at a large area like like banks and office. A wide area network is a telecommunications network that extends over a large geographical area for the primary purpose of computer networking. Wide area networks are often established with leased telecommunication circuits
The significant difference between them is the geographical area they cover. When we consider the order, PAN is capable of providing network connection around a person, next comes LAN which covers a smaller area; then comes MAN; it covers an area larger than LAN & WAN is the largest of all.
