Networking and Information Technology

Networking: Networking involves the practice of connecting computers and other devices to share resources and information. It forms the backbone of modern communication and data exchange. Here are some fundamental concepts:

Networking Protocols: These are rules and conventions that govern how data is transmitted and received over a network. Examples include TCP/IP (Transmission Control Protocol/Internet Protocol), which is the foundation of the internet.

IP Addressing: IP addresses are unique numerical labels assigned to each device connected to a network. IPv4 (32-bit) and IPv6 (128-bit) are the two main versions of IP addresses.

Subnetting: Subnetting involves dividing a larger network into smaller sub-networks to improve efficiency and security.
