INSY 3303 Exam 2 Review Questions and Answers 100% Pass Access Layer - Answer- The layer that provides network access. Ex. Local Area Network (LAN) ACK (acknowledgement message) - Answer- the part of the ARQ algorithm that lets the sender know that the package has been correctly received without errors. Address Resolution - Answer- the process of translating the application layer address (or server name) of the destination into a network layer address, and in turn translate that into a data link layer address Server Name Resolution - Answer- translation of application layer addresses into network layer addresses and is done using the Domain Name Service (DNS) (Ex. Website URL to IP address) ARP (Address Resolution Protocol) - Answer- A core protocol in the TCP/IP suite that belongs in the Network layer of the OSI model. ARP obtains the MAC (physical) address of a host, or node, and then creates a local database that maps the MAC address to the host's IP (logical) address. ARQ (Automatic Repeat reQuest) - Answer- when a receiver that detects an error simply asks the sender to retransmit the message until it is received without error. Asychronous Transmission - Answer- often referred to as start-stop transmission because the transmitting computer can transmit a character whenever it is convenient, and the receiving computer will accept that character. Baselining - Answer- when designers must review the list of applications that will use the network and identify the location of each, and the information is added to the emerging network documentation. BGP (Border Gateway Protocol) - Answer- a dynamic distance vector exterior routing protocol used on the Internet to exchange routing information between autonomous systems—that is, large sections of the Internet. What are the disadvantages to using BGP? - Answer- It is large, complex, and often hard to administer. Backbone Network (BN) - Answer- A large network to which many networks within an organization are connected. It usually is a network that interconnects all networks on a single site. Bottleneck - Answer- a circuit that is filled almost to its capacity and is the critical point that determines whether users get good or bad response times. Building-Block Network Design Process - Answer- when networks that use a few standard components throughout the network are cheaper in the long run than networks that use a variety of different components on different parts of the network. What is the goal of the Building-Block Network Design Process? - Answer- a simpler design process and a more easily managed network built with a smaller range of components. What are the three steps that are performed in Building-Block Network Design Process? - Answer- 1. Needs Analysis 2. Technology Design 3. Cost Assessment What is a needs analysis? - Answer- the process of understanding the fundamental current and future network needs of the various users, departments, and applications. What is technology design? - Answer- examining the available technologies and assessing which options will meet the users' needs. What is a cost assessment? - Answer- when the relative costs of the technologies are considered. Circuit Loading - Answer- the amount of data transmitted on a circuit Common Carrier - Answer- private companies such as AT&T, Bell Canada, Sprint, and BellSouth that provide communication services to the public. Core Layer - Answer- The third network architecture component and is also known as the campus backbone. This layer connects all the buildings on one campus. Data Center - Answer- The fourth network architecture component and it contains the organization's servers. DHCP (Dynamic Host Configuration Protocol) - Answer- A network service that provides automatic assignment of IP addresses and other TCP /IP confi
