Networking Concepts of Computer

Week 04
Computer Network 
 It is a simply group of interconnected computers. Two or more computers are connected via hardware or software in this system and able to communicate with each other. Example: the internet, ATM, e-banking.

Network Components
 Major components of a computer network are :
-Communication Media
-Interconnecting Devices 
-Computers
-Networking Software
-Applications

Networking Concepts: Basic 

Every computer network functions when having these concepts:
-Topology
-Protocol
-Architecture

Networking Communication Medium 

Some types of link through which the data can be transmitted or transferred from one computer to another.
-Medium may be physical cable, such as twisted air, coaxial.
-Medium may also be wireless
-Physical interface to medium is usually network interface card.

 Types of Network

The basic purpose of network is to enable effective communication,share resources and facilities centralized management of data. Different network serves different purpose for users. There are three types of network:- 
        1. LAN ( local area network)
        2. MAN (metropolitan area network)
        3. WAN (wide area network)
Beside these there are several types of network and they are
         - peer-to-peer network
         - server based network
         - SAN (storage area network) 
         - hybrid network

Reflection

I finished my fourth week in my ICT class. By this week I learned about computer network. I also learned how network is working,its components,its types and its communication channel. This week was important for me.
