What is network? What are the different types of network? Example.

Answer:

Network: A network is a group of two or more computer systems linked together. Examples include local-area networks (LANs) and wide-area networks (WANs).



Different types of network: Computer network can be classified into three classes_
1.      LAN (Local Area Network).
2.      MAN (Metropolitan Area Network).
3.      WAN (Wide Area Network).

LAN (Local Area Network):This is one of the original categories of network, and one of the simplest.  LAN networks connect computers together over relatively small distances, such as within a single building or within a small group of buildings.

MAN (Metropolitan Area Network):This is another of the original categories of network, and slightly more complex in nature. WAN networks connect computers together over large physical distances, remotely connecting them over one huge network and allowing them to communicate even when far apart. The Internet is a WAN, and connects computers all around the world together.


WAN (Wide Area Network):This is a network which is larger than a LAN but smaller than a WAN, and incorporates elements of both. It typically spans a town or city and is owned by a single person or company, such as a local council or a large company.

Differences between positional and non-positional number system?

Answer: Positional Number System: In positional number system, there are only a few symbols called digits, and these symbols represent different values depending on the position they occupy in the number. The value of each digit in such a number is determined by three considerations__ 1.       The digit. 2.       The position of the digit in the number. 3.       The base of the number system.
