Insy 3303 Scott Johnson Chapter 4-6 Exam Questions and Answers 100% Pass Access Layer 167 - Answer- Provides access to the network, network designs begins with it, primary wireless LAN. ACK - Answer- Acknowledgement is a signal passed between communicating, processes, computers, or devices to signify acknowledgment . Address Resolution 130 - Answer- to send a message, must be able to translate application layer address of the destination to the network layer address and translate that to the data link layer address ARP 132 - Answer- stands for address resolution protocol, basically translate the subnet to another computer then it is being processed by all computers in the same LAN.. ARQ 100 - Answer- this stands for automatic repeat request. Once error has been detected, it must be corrected. The simplest, most effective, least expensive, And most commonly used method for error correction is retransmission. With retransmission, a receiver that detects an error simply asks the sender to retransmit the message until it is received without error. There's two types, stop and wait and continuous. Asynchronous Transmission - Answer- is 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- Baselining is a method for analyzing computer network performance. The method is marked by comparing current performance to a historical metric, or "baseline". BGP - Answer- is 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. Although BGP is the preferred routing protocol between Internet sections, it is seldomused inside companies because it is large, complex, and often hard to administer. BN - Answer- A backbone network (BN) is a large central network that connects almost everything on a single company site Bottle neck - Answer- a circuit that is filled almost to its capacity and thus is the critical point that determines whether users get good or bad response times. Building Block Design Process - Answer- many other organizations now use a simpler approach to network design that we call the building-block process. The key concept in the building-block process is that 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. Circuit loading - Answer- the amount of data transmitted on a circuit Common Carrier - Answer- Big phone carriers such as at&T Core layer - Answer- The third network architecture component is the campus backbone (sometimes called the core layer), which connects all the buildings on one campus. The campus backbone is usually faster than the backbones we use inside buildings because it typically carriesmore traffic than they do. We use routers or layer 3 switches that do routing when we design the campus backbone. Cost Assessment - Answer- the relative costs of the technologies are considered DHCP - Answer- - The most common standard for dynamic addressing is Dynamic Host Configuration Protocol (DHCP). Data Center - Answer- The fourth network architecture compon
