E-commerce
E-commerce, short for electronic commerce, is a business transaction that occurs over an electronic network such as the Internet. A customer (consumer) visits an online business through an electronic storefront, which contains product descriptions, images, and a shopping cart. The shopping cart allows the customers to collect purchases. Consumer-to-consumer (C2C) e-commerce occurs when one consumer sells directly to another, such as in an online action.
E-mail
E-mail (electronic mail) is the transmission of messages and files via a computer network. You use an e-mail to create, send, receive, forward, store, print, and delete e-mail messages. Outlook and Window Mail are two popular e-mail programs. An e-mail address is a combination of a user name and a domain name that identifies a user so that he or she can receive Internet e-mail. A user name is a unique combination of characters, such as letters of alphabet and/or numbers that identifies a specific user.
Mailing lists
A mailing list, also called a distribution list, is a group of e-mail names and address given a single name. To add your e-mail name and addresses to a mailing list, you subscribe to it. To remove your name, you unsubscribe from the mailing list.
Instant messaging
Instant messaging (IM) is a real-time Internet communications service that notices you when one or more people are online and then allows you to exchange messages or files or join a private chat room with them.
Chat rooms
A chat is a real-time typed conversation that takes place on a computer. Real time means that you and the people with whom you are conversing are online at the same time.
VoIP
VoIP, (Voice over IP, or Internet protocol) also called Internet telephony, enables users to speak to other users over the Internet. To place an Internet telephone call, you need a high-speed Internet connection (such as DSL or cable modem).
FTP
FTP (File Transfer Protocol) is an Internet standard that permits file uploading and downloading (transferring) with other computers on the Internet. Uploading is the opposite of downloading. An FTP server is a computer that allows users to upload and/or download files using FTTP
Newsgroups and message boards
A newsgroup is an online area in which users have written discussion about a particular subject. To participate in a discussion, a user sends a message to the newsgroup, and other users in the newsgroup read and reply to the message. A popular Web-based type of discussion group that does not require a newsreader is a message board.
