PComputer network A computer network is simply two or more computers connected together so they can exchange information. A small network can be as simple as two computers linked together by a single cable. This course introduces you to the hardware and software needed for a network‚ and explains how a small network is different from larger networks and the Internet. Most networks use hubs to connect computers together. A large network may connect thousands of computers and other devices together

A wireless LAN or WLAN is a wireless local area network‚ which is the linking of two or more computers without using wires. It is the same as LAN‚ but has a wireless interface. WLAN utilizes spread-spectrum technology based on radio waves to enable communication between devices in a limited area‚ also known as the basic service set. This gives users the mobility to move around within a broad coverage area and still be connected to the network. Wireless Local Area networks (WLANs) have been employed

CHAPTER ONE 1.0 SIWES INTRODUCTION The Students Industrial Work Experience Scheme (SIWES) is one of the Federal Government policies established under decree No 47 of 1971 of industrial training fund. It’s also a skill-acquisition programme designed for the tertiary institutions as a complementary programme to the theoretical education and laboratory and workshop practices engaged in by students in tertiary institutions which‚ by industrial standards‚ are inadequate or insufficient to serve the

equipment will be used to build the LANs at the offices. Then the LANs will be connected to the WAN to allow for easier communication and data transfer between the offices. The headquarters in Atlanta‚ Georgia will be home to corporate operations‚ marketing department‚ administrative staff‚ and the accounting department. This branch of the company needs a strong network since it is the center of the company. A fiber optic line will be used as the backbone of the LAN at the Headquarters. Ethernet cables

Web surfing determines what a user can do on company time with company resources. Internet is when the user has access to the internet what types of controls should the organization have on the certain internet sites being accessed.

This paper will also cover routing concepts‚ along with some comparisons including routed vs. routing protocols‚ Classful vs. classless protocols‚ and distance vector vs. link state protocols. Switching The definition of a switch or network switch is a small device that joins multiple computers together‚ working on layer two of the OSI‚ to form a local area network or LAN. Network switches are also known as smart hubs. Rather than

amongst the buildings‚ which means we have to build a backbone to connect all three LANs. Before addressing the connectivity issues amongst the buildings‚ lets first look at the current topologies in each building; 2 Ethernet and token ring. I recommend going with Ethernet‚ it is a simpler topology‚ which has less room for errors. With 100 computers in each building I would recommend 100base-T Switched Ethernet LANs‚ in all three buildings. The type of circuit is dedicated point to point. In order
