Study Notes
- A computer network is a collection of interconnected computers, enabling information sharing and communication between devices.
- Computers in a network can send and receive messages, allowing for resource sharing (printers, scanners, disk drives) and multiple users to communicate and exchange data.
- Data communication consists of a message (information), sender (device initiating transmission), receiver (device receiving the message), and medium (physical path for message transmission).
- Types of computer networks include Local Area Networks (LANs), Wide Area Networks (WANs), Metropolitan Area Networks (MANs), Campus Area Networks (CANs), Intranets, and Personal Area Networks (PANs).
- LANs consist of geographically close computers (computer lab), while WANs connect computers farther apart (telephone lines or radio waves for example).
- Internet is a global network connecting millions of computers, consisting of networks in hundreds of countries and using existing telephone and communication networks for data transfer.
- It is the largest part of the Internet, providing access to news, opinions, and various services like web browsing, email, and file transfer (Gopher, Telnet, FTP).
