Computer Networking Basic
In this course, you will get to know about the basics of computer networking and then will understand the advanced level course step by step. Moreover, we will use a packet tracer for network simulation.
Computer networking basics involve the foundation principles and components necessary for devices to communicate and share resources efficiently. At its core, computer networking facilitates the exchange of data between devices such as computers, servers, printers, and other peripherals.
Key components of computer networking include:
- Devices: This encompasses computers, routers, switches, access points, and other hardware that participate in the network.
- Transmission Media: Networks can utilize various transmission media, including wired (such as Ethernet cables) and wireless (like Wi-Fi or Bluetooth) connections, to transfer data between devices.
- Protocols: Networking protocols define the rules and conventions for communication between devices. Examples include TCP/IP (Transmission Control Protocol/Internet Protocol), which governs data transmission across the Internet, and HTTP (Hypertext Transfer Protocol), used for web browsing.
- IP Addresses: Every device on a network is assigned a unique identifier called an IP (Internet Protocol) address, allowing for accurate routing of data packets.
- Network Topologies: The arrangement of devices and connections in a network is known as its topology. Common topologies include bus, star, ring, and mesh.
Understanding these fundamental concepts is crucial for designing, implementing, and maintaining computer networks. Mastery of networking basics forms the foundation for more advanced topics such as network security, administration, and optimization.
