ADWARE A program that downloads on your computer when a user installs a freeware program game or utility Generally adaware enables sponsored advertisements to appear in a section of a browser window or as a pop up ad Also referred to as Malware or Spyware CGS 2100 EXAM 2 STUDY GRID OVERVIEW IMPORTANT TERMS QUESTIONS A code to provide consistent means for representing letters other characters

NETWORKS CLIENT SERVER NETWORKS Client server networks have many of the same components as peer to peer networks as well as some components specific to client server networks including servers a network topology transmission media network adapters network navigation devices network operating system NOS software Each topology has its own advantages disadvantages Topology selection depends on two main factors 1 The network budget and 2 The specific needs of network users such as speed or fair allocation of resources CLIENT SERVER NETWORKS In addition to wireles media three main cable types are used twisted pair cable coaxial cable and fiber opticv cable CLIENT SERVER NETWORKS Twisted pair cable consists of pairs of wires twisted around each other in order to reduce interference CLIENT SERVER NETWORKS Coaxial Cable is the same type of cable used by your cable TV company to rubn a signal into your house CLIENT SERVER NETWORKS CLIENT SERVER NETWORKS Wireless media uses radio waves to send data between nodes on a network CLIENT SERVER NETWORKS Fiber Optic Cable uses bundles of glass or plastic fiber to send signals using light waves It provides the largest bandwidth but is ezxpensive and difficult to install Without a network adapter a computer could not communicate on a network A network adapter provides three critical functions First it takes low power data signals generated by the computer and converts them into higher powered signals that can transverse network media easily Second it breaks the data generated by the computer into packets and packages them for transmission across the network media Last it acts as a gatekeeper to control the flow of data to and from the computer CLIENT SERVER NETWORKS Switches are devices that read the addresses of data packets and retransmit a signal to its destination instead of to every device connected to the switch CLIENT SERVER NETWORKS Bridges are devices used to send data between two different segments collicion domains of the same network CLIENT SERVER NETWORKS Routers are used to route data between two different networks such as between business networks and the Internet CLIENT SERVER NETWORKS Network oprerating system NOS software needs to be installed on each computer and sever connected to a client sever network in order to provide the services necessary
