Study Notes
Computer Networks Fundamentals - Lecture 1: Introduction
- Course: NET 110
- Topic: Introduction to Computer Networks
- Lecturer: Dr. Kuljeet Kaur
-
Network Categories:
- Local Area Network (LAN): Covers a small area, typically less than 2 miles, like an office or building.
- Wide Area Network (WAN): Spans large distances, potentially across countries or the world.
- Metropolitan Area Network (MAN): Covers a city or a portion of a city, in between LAN and WAN.
-
LAN Topologies:
- Bus: Data travels along a single cable.
- Ring: Data circulates in a loop.
- Star: Devices connect to a central hub or switch.
-
LAN Characteristics:
- Primarily private networks within a single office, building, or campus.
- Can be simple (two computers and a printer) or complex (including audio-visual peripherals).
- Designed to share resources (printing, audio-visual content) among connected devices.
-
WAN Characteristics:
- Switched WAN: Utilizes switches or routers to route data through the network
- Point-to-Point WAN: Network with a direct connection between two locations or endpoints
-
MAN Characteristics:
- Lies in between LAN and WAN in terms of network size
- Covers the area within a city or part of a city
- Designed for high-speed connectivity to the internet.
Internet
- Impact: Revolutionizes daily life, impacting business and leisure.
- Function: Facilitates communication, provides access to organized information.
-
Topics:
- Brief History
- Internet Today (ISPs)
Protocols and Standards
-
Protocols:
- Rule-based standards for communication processes, including data structure and format (Syntax), bit meaning (Semantics), and sending timing constraints (Timing).
-
Standards:
- Agreed-upon rules set by manufacturers, vendors, government agencies, etc.
Internet Standard
- Definition: A thoroughly tested specification necessary for the Internet.
- Internet draft: A working document undergoing development without official standing; lasting 6 months.
Reading Assignment
- Chapter 1 of the textbook.
Exercises
- Data Communications System Components: List the five core elements of a data communication system.
- Bit Representation: Calculate the maximum number of colours capable of representation with 16-bit pixel values.
- Network Topology: Determine the required cable and port numbers for a mesh topology with 6 devices.
- Network Type: Identify whether a home network with 2 computers connected via an Ethernet hub is a LAN, MAN, or WAN, and justify your answer.
- Connectivity Issues: Analyse the consequences of a network connection failure in various topologies (mesh, star, bus, ring).
