Computer Network

A computer network is a set of computers connected together for the purpose of sharing resources. The most common resource shared today is connection to the Internet. Other shared resources can include a printer or a file server.

 A computer network is a system in which multiple computers are connected to each other to share information and resources.
Characteristics of a Computer Network:-
·        Share resources from one computer to another.
·        Create files and store them in one computer, access those files from the other computer(s) connected over the network.
·        Connect a printer, scanner, or a fax machine to one computer within the network and let other computers of the network use the machines available over the network.
A computer network is a set of connected computers. Computers on a network are called nodes. The connection between computers can be done via cabling, most commonly the Ethernet cable, or wireless through radio waves. Connected computers can share resources, like access to the Internet, printers, file servers, and others. A network is a multipurpose connection, which allows a single computer to do more.
Following is the list of hardware's required to set up a computer network.
  • Network Cables
  • Distributors
  • Routers
  • Internal Network Cards
  • External Network Cards
Network and Computer Systems Administrators are responsible for the day-to-day operation of an organization's computer networks. They organize, install, and support an organization's computer systems, including: Local area networks (LANs) Wide area networks (WANs)

Characteristics of Computer:-

Computers of all sizes have common characteristics - speed, arithmetical and logical operations, accuracy, reliability, storage, retrieving data and programs, automation, versatility, communications, diligence, feelings, consistency and precision. Computers are the foundation of business, travel, and leisure life today. Computers provide the processing speed required by all facets of society. The quick service we expect at the bank, at the grocery store, on the stock exchange, and on the Internet are dependent on the speed of computers.    Computers are extremely reliable as well. Most errors are caused by humans, not computers. Computers are capable of storing enormous amounts of data that must be located and retrieved very quickly. The capability to store and retrieve volumes of data is at the core of the Information Age. Now-a-days computer is playing a main role in everyday life it has become the need of people just like television, telephone or other electronic devices ...

Characteristics Of Computer

                        1. SPEED :- Computer is very fast calculating device. It can execute basic operations like substraction,addition,multiplication and division at a few microseconds. It can move and copy data at a speed in the order of billion instruction per second.  2. ACCURACY :- Computer always gives accurate results. The accuracy of Computer does not go down when they are used continuously for hours together. It always gives accurate results.  3. STORAGE CAPACITY :- Computer have a very large storage capacity. A  large volume of information can be stored in the memory of computer and information can be retrieved correctly when desired.  4. VERSATILITY:- The working of computer with different types of data is known as versatillity. That means computer can perform different types of job efficiently. Computer can works with differents type of data and informa...
