Introduction The Concept Of Network
Describe Network Architecture
Network architecture refers to the way network device and services are structured to served the connectivity needs of client devices.
It is mainly focuses on the function of the networks
It is also known as network model or network design
Indentify the types of Cloud Computing
Describe The Types Of Network Topologies (BAS,RING ,MESH,STAR)
In a bus topology, all devices are connected to a single central cable, known as a backboneData is transmitted along the backbone,and devices listen for data addressed to them.If the backbone cable fails,the entire network can be disrupted.
In a ring topology, each device is connected to exactly two other devices, forming a closed loop.Data travels around the ring until it reaches its destination.failure of one device or cable can disrupt the entire network.
In a star topology, all devices are connected to a central hub or switch.If one cable or device fails, it does not affect the entire network.Commonly used in Ethernet LANs.
In a mesh topology,every device is connected to every other device in the network.This redundancy makes the network highly reliable, as data can follow multiple paths.However,it can be expensive to implement due to the numerous connections..
Different between LAN,MAN,WAN
Faster than WAN
Best LAN types used in internet.
cheaper,not too expensive
Hardware focused in sharing resources
Operate peer to peer
More to private
Metropolitan area network
Either private or public
Maintenance of MAN is more difficult than LAN.
The coverage range etween 10 to 100 kilometer
Since MAN is a wider network than LAN, it provides moderate internet speed up to 50 to 100 mb/s
Maintenance of WAN is very difficult
Either private or public
WAN allows the widest distance transmission but provides lesser internet speed in comparison to LAN and WAN less than 100 mb/s
The transfer of the internet from one continent to another via sea is an example of WAN
Explain the concept of network
A network is the combination of two or more computers and their connecting links. A physical network is the hardware (equipment such as adapters, cables, and telephone lines) that makes up the network. The software and the conceptual model make up the logical network.
Computer networking refers to interconnected computing devices that can exchange data and share resources with each other. These networked devices use a system of rules, called communications protocols, to transmit information over physical or wireless technologies.
