True and False questions (two point each): (A > True, B > False) Compression is the ability of number of devices to share a transmission facility Growth in services and growth in traffic capacity go hand in hand. Guided media, also called wireless, provide a physical means for guiding 1. 2. 3. waves through seawater. 4. Thermal noise is also referred to as gray noise 5. Frame relay is a technology widely used in LAN 6. The header for UDP segment is 20 Octets 7. The two commonly used transport level protocols used as part of the TCP/1P protocol suite are TCP and IP 8. Crosstalk is caused by external electromagnetic interferences 9. One of the key features of a protocol is Semantics 10. 10. TCP/IP mode has seven layers, starting from physical and ending with application which is responsible for format of data blocks Data deals with the transmission of signals in a reliable and efficient manner distortion occurs because the velocity of propagation of a signal through a guided medium varies with frequency 13. ATM uses variable-length packets called cells 14. Total number of IP addresses in IPv6 is 23 15. Each protocol provides a set of rules for the exchange of data between systems 16. As each packet leaves the source, it contains header and some portion of the user data. The user data is needed for proper functioning of the network. . The advantages of digital signaling are that it is generally cheaper than analog signaling and is les susceptible to noise interference
