Networking Basics Every IT Professional Should Know
In today’s technology-driven world, networking is a vital skill for IT professionals. Understanding the foundational concepts of networking is essential for anyone seeking to advance their career in Information Technology. This blog will highlight the important networking terms and concepts covered in the Level 4 Diploma in Information Technology – Networking.
What is Networking?
Networking allows devices to connect and communicate with each other. Let’s explore some important terms:
- IP Address: A unique address assigned to every device connected to a network.
- Subnetting: The practice of dividing a network into smaller, manageable pieces.
- Network Topology: The arrangement of different elements (links, nodes, etc.) in a computer network.
Common Networking Devices
Networking is facilitated by several types of devices. Here are a few:
- Modem: Connects a network to the Internet.
- Access Point: Allows wireless devices to connect to the wired network.
- Hub: A basic device that connects multiple computers in a network.
Understanding Networking Models
Networking models are essential for design and implementation. The two primary models include:
- The OSI Model - A conceptual framework used to understand network interactions.
- The TCP/IP Model - A more practical framework that outlines the communication protocols used on the Internet.
