Mailing list

A mailing list is a collection of names and addresses used by an individual or an organization to send material to multiple recipients. On the Internet, mailing lists include each person‚Äôs e-mail address . The term is often extended to include the people subscribed to such a list, so the group of subscribers is referred to as ‚Äúthe mailing list‚ÄĚ, or simply ‚Äúthe list‚ÄĚ.

News Group

Same as forum, it is an on-line discussion group. On the Internet, there are literally thousands of newsgroups covering every conceivable interest.

Newsgroups are discussion groups. To read messages posted to a particular newsgroup, you must first subscribe to the newsgroup.

Newsgroup is an excellent way to share information, to get answers, and to give your opinion to online subjects.


This is a service that searches through Usenet newsgroups to find specific content. Usenet search engines can be used to search for anything. For example, you might search for photos of a famous person (such as Bill Gates)

If you want to search for regular, text-based articles, the easiest way is to use the Google Groups Web site.

1. Mailing list

2. Newsgroup





File Sharing

Network file sharing is the process of copying data files from one computer to another using a live network connection.

Before the Internet and home networks became popular, data files were often shared using floppy disks. Nowadays, some people still use CD-ROM / DVD-ROM disks and USB sticks (Flash drives) for transferring their photos and videos, but networks give you more flexible options.

FTP File Transfers

This is a method of sharing files where a central computer called the FTP server holds all the files to be shared, while remote computers running FTP client software can log in to the server to obtain copies.

P2P ‚Äď Peer to Peer File Sharing

Peer to peer (P2P) file sharing is a popular method for swapping large files on the Internet, particularly music and videos. Unlike FTP, most P2P file sharing systems do not use any central servers but instead allow all computers on the network to function both as a client and a server.



A computer network is a set of computers connected together for the purpose of sharing information and resources. Networks are used to provide easy access to information, thus increasing productivity for users.

Benefits of networking

There are three main benefits of a network

File Sharing

In a computer network, one can view, modify, and copy files stored on a different computer on the network just as easily as if they were stored on your computer.

Resource Sharing

Resources such as printers, fax machines, Storage Devices (HDD, FDD and CD Drives), Webcam, Scanners, Modem and many more devices can be shared in a network.

Program Sharing

One can also share programs on a network. For example programs such as Microsoft Office, can be shared by computers in the network.

Types of Networks

Local Area Networks

Local area network (LANs) is a type of network connected within a very close geographic area, such as a floor of a building.

Metropolitan Area Networks

This is a large computer network which extends to a city or town or a community.

Wide Area Networks

This is a computer network in which the computers connected may be far apart. This network could exist between a city and another city, or even between two countries.


An intranet is basically a network that is local to a company. In other words, users from within this company can find all of their resources without having to go outside of the company.


An extranet is an extended intranet, where certain internal services are made available to known external users or business partners at remote locations.
