Answer:

Information and Resource Sharing: Computer networks allow organizations having units which are placed apart from each other, to share information in a very effective manner. Programs and software in any computer can be accessed by other computers linked to the network. It also allows sharing of hardware equipment, like printers and scanners among varied users.

Retrieving Remote Information: Through computer networks, users can retrieve remote information on a variety of topics. The information is stored in remote databases to which the user gains access through information systems like the World Wide Web.

Speedy Interpersonal Communication: Computer networks have increased the speed and volume of communication like never before. Electronic Mail (email) is extensively used for sending texts, documents, images, and videos across the globe. Online communications have increased by manifold times through social networking services.

E-Commerce: Computer networks have paved way for a variety of business and commercial transactions online, popularly called e-commerce. Users and organizations can pool funds, buy or sell items, pay bills, manage bank accounts, pay taxes, transfer funds and handle investments electronically.

Highly Reliable Systems: Computer networks allow systems to be distributed in nature, by the virtue of which data is stored in multiple sources. This makes the system highly reliable. If a failure occurs in one source, then the system will still continue to function and data will still be available from the other sources.

Cost–Effective Systems: Computer networks have reduced the cost of establishment of computer systems in organizations. Previously, it was imperative for organizations to set up expensive mainframes for computation and storage. With the advent of networks, it is sufficient to set up interconnected personal computers (PCs) for the same purpose.

VoIP: VoIP or Voice over Internet protocol has revolutionized telecommunication systems. Through this, telephone calls are made digitally using Internet Protocols instead of the regular analog phone lines.

Computer network

In basic terms, computer network is a type of network that allows computers to communicate with other computers via medium. There are mainly 3 types of network: WAN , LAN and MAN.

WAN - Wide Area Network

Wide area network is provided for large geographical areas like schools, offices, colleges and institutions. WAN is established with the least telecommunication circuits. WAN is used to transmit data and information at large distance.

Most of the private WAN networks uses 24 Bit block for communication service.

Circuit-switched telephone lines, radio wave transmission, and optical fiber are some of the technologies used in Wide Area Network.

WAN provides us High speed internet upto 400 gigabit. AT&T has successfully launched their broadband WAN service to provide high speed internet.

LAN - Local Area Network

Local Area Network interconnects the computers at small geographical area such as schools and colleges. Ethernet and Wi-Fi are the two common technologies used in Land Area Network. In this type of network, Cabling is a common technology that is used for interconnecting two different computers.

Local Area Network was created in 1960 by the students of university.

LAN provides high speed internet using Ethernet cables. Ethernet cables data is later converted in wireless network using routers.

Wireless media is a common thing nowadays. Today, every smartphone, tablet and desktop have built in wifi connection, which helps to use internet without Ethernet cables wireless.

NetBEUI, IPX/SPX, AppleTalk are the protocols used in Local Area network for data communication.

MAN - Metropolitan Area Network

MAN is a type of network that covers very high Geographical areas like districts, towns and villages. The MAN network is transmitted through the tower in the form of waves, when this waves enters in our smartphone, they are later interrupted by our smartphone and hence we can use it.

Metropolitan Area Network is also called as Wide Area Network (WAN)
MAN network is used since 1994 for data communications.
This network is provided from ISP to city and from towers, this network is later converted into waves.
Business, education and government entities uses Metropolitan Area Network.
