The fundamentals of IT networking include:
- Network Topology: This refers to the physical or logical layout of a network. There are different types of network topologies such as bus, star, mesh, and ring.
- Network Protocols: Network protocols are a set of rules that govern the communication between devices on a network. Some of the most common protocols include TCP/IP, HTTP, DNS, SMTP, and FTP.
- Network Devices: Network devices are the hardware components that facilitate the communication between devices on a network. These devices include routers, switches, hubs, modems, and firewalls.
- Network Security: This refers to the protection of a network from unauthorized access, theft, or damage. Network security measures include firewalls, antivirus software, and intrusion detection and prevention systems.
- Network Administration: This refers to the management and maintenance of a network. It involves tasks such as network monitoring, troubleshooting, and configuration management.
- Network Services: These are the services that are provided by a network such as email, file sharing, printing, and remote access.
- Network Performance: This refers to the ability of a network to meet the requirements of its users. Network performance is measured in terms of factors such as bandwidth, latency, and throughput.
- Network Standards: These are the agreed-upon rules and guidelines that ensure the interoperability of devices and systems on a network. Standards such as Ethernet, Wi-Fi, and TCP/IP are essential for the proper functioning of a network.
