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).
Explore the basics of computer networks, including the types of networks like LANs, WANs, MANs, and more. Learn about data communication, resource sharing, and the global network known as the Internet.
