Study Notes

Exploring ICT's Foundation: Networking Basics

Information and Communication Technology (ICT) is a vast field encompassing various disciplines with one of its foundational pillars being networking. In this context, we'll delve into how networks facilitate communication and data exchange—the heartbeat of our increasingly interconnected world.

When discussing networking, it can help to understand several fundamental concepts:

A computer network is a collection of multiple devices connected using cables, wireless signals, or other technologies to enable information sharing between them.
A network topology outlines how computers and devices connect within a given network, such as bus, star, ring, mesh, tree, or hybrid arrangements.
The OSI Model, developed by the International Organization for Standardization (ISO), divides networking tasks into seven layers, including physical, data link, network, transport, session, presentation, and application layers. This model serves as a framework for understanding complex networking protocols.

Now let's explore some specific areas related to ICT networking:

Internetworking

Internetworking refers to connecting two or more separate LANs (Local Area Networks) or WANs (Wide Area Networks) through routers. By bridging these disparate systems, internetwork provides seamless access to resources across large distances.

Routing Protocols

Routing protocols determine the most efficient pathway between nodes over a network. Two common routing methods are Distance Vector Routing (DVR) and Link State Routing (LSR):

Distance Vector Routing: This method uses distance vectors, which specify the next hop and metric to reach each destination, based on the available connections within a single router's perspective.
Link State Routing: Instead of broadcasting entire route tables like DVR does, LSR shares only the state of links directly connected to each router among all participating nodes.

Switching

Network switches increase network efficiency by facilitating traffic flow while avoiding bottlenecks caused by shared bandwidth issues inherent in hub technology. Switches work by examining frames passing along their ports and determining where they need to forward those frames based on MAC addresses. They form interactive learning databases called Content Addressable Memories (CAMS) to manage frame distribution.

In summary, ICT’s networking dimension presents a coherent infrastructure supporting ubiquitous digital communications. Its advancements have allowed us to establish global computer systems from local areas, reshaping human interaction and organizational dynamics worldwide. As new technological innovations emerge, so too will opportunities to refine and extend our present grasp of the fundamentals introduced herein.
