2. Computer Communications A process in which two or more computers or devices transfer’s data, instruction, and information. For successful communications you need the following: A sending device – initiates an instruction to transmit data, instructions, information A communications device – connects the sending device to a communications channel A communication channel – transmission media on which the data, instructions, or information passes. A receiving device – accepts the transmission of data, instruction of information

3. Uses of Computer Communication

4. Internet – a worldwide collection of networks that links millions of businesses, government agencies, educations, and individual Web – worldwide collection of electronic documents on the internet that users access through Web browser. E-Mail – or Electronic Mail, is a type of mail message that is sent through the network. Instant Messaging – A Real-time internet communication service that notifies you when one or more people are online, then allows you to exchange messages, pictures, files, audio and video Chat rooms – a real-time typed in conversation that takes place on a computer connected to a network, that also allows you to exchange messages, pictures, files, audio and video.

Internet telephony – a conversation takes place over the internet using a telephone connected to a desktop computer. FTP or File Transfer Protocol – Internet standard that permits or allows user to upload or download files. Web Folder – Known as HTTP or Hyper Text Transfer Protocol server, allows users to publish documents and other files. Video conferencing – real-time meeting over two person, use the internet to transmit audio and video signal. Fax Machine or Computer fax/modem – transmits and receives documents over the phone line.

6. Network Communications Standard Data is processed in one of two ways: Analog or Digital. A computer, by contrast, is Digital which means it can process data in two discrete states: Positive (ON or 1) Non-Positive (OFF or 0). The 1 and 0 represent the two digits used by the binary number system, this system is at the heart of digital computing.

7. Computer Network A collection of computers and devices connected together via communications devices and transmission media.

8. Classifications of Network Local Area Network (LAN) – A network that connects computers and devices in a limited geographical area such as home, school computer laboratory, office building, or closely positioned group of building. Each computer on the network is called a Node.

9. LOCAL AREA NETWORK (LAN)

10. Wireless Local Area Network (WLAN) – is a LAN that uses no physical wires. Computers and devices that access a wireless LAN must have a built-in wireless capability, or the appropriate wireless network card, PC card, or Flash card. Wireless LAN communicates with wired LAN for access to its resources.

11. WIRELESS LOCAL AREA NETWORK (WLAN)

12. Metropolitan Area Network (MAN) – is a high speed network that connects local area networks in a metropolitan area such as a city or town.

13. METROPOLITAN AREA NETWORK (MAN)

14. Wide Area Network (WAN) – is a network that covers a large geographical area (such as a city, country, or the world) using a communications channel that combines many types of media such as telephone lines, cables and radio waves. The internet is the world’s largest WAN.
