- 4. Definition of Computer Networking Computernetworking is the practice of interconnecting computers and devices to share resources and information. It facilitates communication and includes hardware like routers and software protocols to ensure data is transmitted accurately across various mediums.
- 5. Types of Networks Networktypes include Local Area Networks (LAN), typically covering a small geographic area, Wide Area Networks (WAN) that span larger distances, and Metropolitan Area Networks (MAN) which are larger than LANs but smaller than WANs. Each type serves different networking needs depending on scale and connectivity requirements.
- 6. Components of aNetwork A computer network consists of several key components including computers, servers, switches, routers, and firewalls. Computers are end-user devices that access the network, while servers provide resources. Switches connect devices within a LAN, routers direct data between different networks, and firewalls provide security by controlling incoming and outgoing traffic.

- 8. Introduction to Networking Protocols Networkingprotocols are standardized rules that determine how data is transmitted and received over a network. These protocols define the format of the data, the method of transmission, and the rules for establishing a connection. They ensure compatibility and communication between different network devices.
- 9. TCP/IP Model The TCP/IPmodel, designed by the Department of Defense, describes the protocols used for the Internet. It consists of four layers: the Link layer (physical hardware and connections), the Internet layer (routing and addressing), the Transport layer (data transfer, ensuring reliability through TCP), and the Application layer (application-level protocols).
- 10. Common Network Protocols Commonnetwork protocols include HTTP (Hypertext Transfer Protocol) for web communication, FTP (File Transfer Protocol) for transferring files, SMTP (Simple Mail Transfer Protocol) for email transmission, and DNS (Domain Name System) for resolving domain names. These protocols are essential for various Internet services and applications.
- 11. Conclusions Understanding computer networkingbasics, components, and protocols is essential for effectively managing and utilizing network resources. This knowledge serves as the foundation for studying more advanced networking concepts and technologies.
