Study Notes
Computer Communication
- Computer communication is the process of transferring data, instructions, and information between computers.
- Earlier, only large computers had communication capabilities, but now even smaller computers and devices can communicate directly with each other.
Components of Computer Communication
- SENDER: a device that initiates sending data, instructions, or information, such as a computer or mobile device.
- COMMUNICATION CHANNEL OR TRANSMISSION MEDIA: a medium through which data travels, such as cables, microwave stations, or satellites.
- RECEIVER: a device that accepts the transmission of data, instructions, or information, such as a computer or mobile device.
- PROTOCOL: a set of rules that outlines characteristics of how two devices communicate, including data format, coding schemes, and sequence of data transfer.
Computer Network
- A computer network is a collection of computers and devices connected by communication channels.
- Networks can be small, connecting two computers, or large, covering different parts of a city or even the whole world.
- Networks allow people to share hardware, software, data, and information, and facilitate communication.
Need for a Network
- Sharing resources saves time and money with the help of a network.
- Resources that can be shared include hardware devices, software programs, data, and information.
Data and Information Sharing
- In a network environment, authorized users can access data and information stored on other computers in the network.
- A large company can store a database of customer information on a server, and authorized users can access it.
Hardware Sharing
- In a network environment, each computer can access and use hardware available on the network.
- Examples include sharing a printer among multiple computers.
Software Sharing
- Network lets people gain access to software programs stored on a central computer.
- Individuals can access and work with these programs using their own computer.
Transfer Funds
- Network allows users to exchange money from one bank account to another via Electronic Fund Transfer (EFT).
- Examples include use of credit and debit cards, direct deposit of funds, online banking, and online bill payment.
Network User
- When a computer is part of a network, users can access local resources, such as files, folders, and computer hardware.
- Examples include accessing a printer attached to another computer.
