CMIT-130 Networking Fundamentals (Content) Computer Science Which LAN protocol supports older Microsoft Windows-based operating systems (support ending with Windows XP and Server 2003)? - ANSWER-NetBEUI (NetBIOS Extended User Interface) Which LAN protocol supports older Novell NetWare operating systems? - ANSWERIPX/SPX (Internetwork Packet Exchange/Sequenced Packet Exchange) Which LAN protocol supports older Apple Macintosh operating systems? - ANSWERAppleTalk Which LAN protocol supports UNIX, Linux, newer MS Windows-based operating systems, modern Apple Macintosh systems, and IBM mainframe operating systems? - ANSWER-TCP/IP True of False. One advantage of IPX/SPX (Novell NetWare) is that is can be routed, meaning that it can transport data over multiple networks in an enterprise. - ANSWERTrue T or F. NetBEUI (a LAN protocol) is supported in Windows XP, Windows Server 2003, and higher Windows versions. - ANSWER-False. NetBEUI proved to have some significant drawbacks because this protocol cannot be routed and can cause unnecessary traffic. T or F. AppleTalk (a LAN protocol) is a peer-to-peer network protocol. - ANSWER-True Which version of Mac did AppleTalk become no longer supported? - ANSWER-Mac OS X 10.6, Snow Leopard What is a disadvantage of using AppleTalk? - ANSWER-1. Not as effective as TCP/IP for communicating with non-Macintosh computers 2. AppleTalk is not used on the internet This protocol establishes a communications session and helps to ensure communications are reliable. - ANSWER-TCP This protocol enables data transfer and routing on a network through the use of packet addressing. - ANSWER-IP (internet protocol) When is the UDP protocol used? - ANSWER-UDP is sometimes used with IP instead of TCP when applications require low overhead and communications reliability is of less concern. Typical LAN protocols include (list them). - ANSWER-TCP/IP IPX/SPX NetBEUI AppleTalk List the evolution path of the Windows OS. - ANSWER-1, 2, 3.1 NT, 95, 98, 2000/ME, XP, Vista, 7, 8, 10 (released in 2015) Who created the TCP/IP protocols and why? - ANSWER-The Advanced Research Projects Agency (ARPA) created TCP/IP to improve upon the Network Control Protocol (NCP) for enabling communications across university, research and Department of Defense computers. ___ is a transport protocol (OSI Transport layer or Layer 4) that establishes communications between software application processes initiated by users on a network. - ANSWER-TCP (Transmission Control Protocol) TCP is a ___ protocol that establishes communications between software application processes initiated by users on a network. - ANSWER-transport (OSI Layer 4) T or F. TCP provides for reliable end-to-end delivery of data by monitoring the accurate receipt of frames and by controlling data flow. - ANSWER-True How does TCP provide reliable end-to-end delivery of data? - ANSWER-It accomplishes this by sequencing and acknowledging frames. The number of data bytes transmitted in a frame is called the _____ _____. - ANSWERSliding window What are the main 4 functions of TCP? - ANSWER-Monitor for requests Establish sessions with other TCP nodes Transmit/receive data Close transmission sessions T or F. TCP and UDP ports are not susceptible to computer attackers looking to break into systems. - ANSWER-False, just the opposite. T or F. The TCP header is a minimum of 20 bytes in length. - ANSWER-True The TCP frame contains a _____ and _____ _____ and is called the TCP _____. - ANSWER-header, data payload, segment T or F. TCP and IP ports support full- and half-duplex communications. - ANSWER- Continues...
