Chapter 1 Introduction 1.1 Background of the Study The development of the computer technology and network communication technology makes it possible for human’s society to enter an era of information. But nowadays‚ most of the computer laboratory is still in the primitive stage of manual management. This not only is extremely inconsistent with the development of computer science‚ but also wastes much of manpower and material resources‚ so it has been an emergent question for computer laboratory

TUTORIAL 5 1. List and describe three (3) major LAN topologies? Topologies can define as the layout of a network. There are really three basic types of topologies. They are Star‚ Bus‚ and Ring. In a star topology‚ all computers and devices are connected to a centrally located hub or switch. The hub or switch collects and distributes the flow of data within the network. It’s better to use a switch than a hub because a switch transmits the data to the intended recipient rather

was known as ’Advanced Research Projects Agency Network’ (ARPANET). Since then‚ networking technology and architecture evolved in complexity and sophistication‚ to provide us with the internet. As internet is open to all‚ In order to make document sharing within organizations more secure‚ an intranet is created. Introduction: An intranet is a private computer network that allows access only to authorized users within an organization. Often safeguarded with user IDs and passwords‚ intranets are used

CMCN6103 Deric Law CGS00479903 1. Improving Network Topology Draw the topology of the network that you are currently using. Be sure to include addressing structures‚ network architecture‚ and include devices such as core switches‚ workgroup switches‚ firewalls‚ routers‚ and other network devices. Analyze the security of the topology and then draw a proposed new topology. Be sure to include security detection systems as well as security zones. Kazakhstan International School had implemented

Question 1. Define what is thin‚ fat/thick client. Thin-client is a technology whereby it refers to a computer that has multi-tier client server architecture which the end user (client) do not use any hard disk and the programs run and display via browser. The program is actual execute from main server and not from desktop pc. The client which operates as terminal needs to continuously communicate with the server. Thick or Fat client is a technology whereby it also refers to a computer with multi-tier

Q1. Compare between LAN‚ MAN and WAN? A LAN (local area network) is a group of computers and network devices connected together‚ usually within the same building. By definition‚ the connections must be high speed and relatively inexpensive (e.g.‚ token ring or Ethernet). Most Indiana University Bloomington departments are on LANs. A LAN connection is a high-speed connection to a LAN. On the IUB campus‚ most connections are either Ethernet (10 Mbps) or Fast Ethernet (100 Mbps)‚ and a few locations
