CPU A CPU (which is also known as a central processing Unit) is basically the part of the computer of where most of the processing of calculations takes place. some people refer to it as the “brains” of the computer. Processors are used in all types of computers The CPU plugs into something known as a CPU socket which is located on the mother and this socket delivers electrical contact to the microprocessor and to something known as a printed circuit board. In the case of chips with have a big…

that it is easy to install and also easy to troubleshoot when it is not working properly. The disadvantage of the ring topology network is that each computer that is connected to the network relies on each other. This means that if one computer or cable goes down all of the data flow would be interrupted throughout out the network connection. This will cause the network to slow down and eventually the network will collapse until the issue is corrected. Below is an example of what a ring topology…

Morse first noticed it on the transatlantic telegraph cables transmitting messages using dots and dashes and it has not gone way since. He handled it by just slowing down the transmission. Amplitude Time Figure 8 101101 transmitted data Figure 8 shows a data sequence, 1,0,1,1,0, which wish to be sent. This sequence is in form of square pulses. Square pulses are nice as an abstraction…

Task 1 ( P1) Explain how networks communicate. Wired: Used to transfer information over networks some include twisted pair cables, coaxial cables and telephone lines. Wireless: Are used when it is impossible or difficult to install wires or cables it is sends communication signal via microwaves, satellite, infrared signals and so on. Physical Layouts: Ring: Each computer is connected to two other forming a single continuous pathway for signals. Star: Consists of a central switch, hub or…

The World Wide Web is fairly intricate. The World Wide Web was first invented in 1989 by Tim Berners-Lee, at first “he fashioned a kind of “hypertext” notebook. Words in a document could be linked to other files on Berners-Lee’s computer” (128) Berner-Lee’s mind grow and he decide to try and take his finding to the next level by linking other computers to his thus came Hypertext Markup Language (128). Berner-Lee was very intelligent with his invention because he even formed rules for the World…

802.7 IEEE 802.7 is a sub-standard of the IEEE 802 which covers broadband local area networks with a coaxial cable. This standard was developed for cable internet companies. e. 802.11 (a, b, g, n) – Wireless Network Standards 802.11 is the collection of standards setup for wireless networking. They include four different standards including; 802.11a, 802.b, 802.11g and the most…

Q1.Ethernet has become the standard for LAN communications. Give a brief overview of structure of an Ethernet frame. Ethernet and Wi-Fi are the most commonly used technologies to set up Local Area Networks today. It operates by using Carrier Sense Multiple Access Detection (CSMA/CD) to control media access. (Study CCNA, 2016) The structure of an Ethernet Frame is as follows: The Ethernet Frame Structure (Anon., 2013) Explanation: • Preamble: This field is responsible for harmonizing bits…

single one in order to create an image. Cabling: Coaxial: This is the old way of cabling networks. This has now recently started being used in homes, creating broadband services. This cable has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Optical: This is a cable which has a number of optical fibers connected together, these are normally covered in their own protective plastic covers. Optical cables are used for transferring digital and…
