Twisting in a twisted-pair help reduce the Answer length cost noise None of the choices are correct Multiple Choice (Total Point: 1.00) #2 IEEE has defined the specification for wireless which is called Answer IEEE 802.11 IEEE 802.12 IEEE 801.11 IEEE 803.12 Multiple Choice (Total Point: 1.00) #3 Which error detection method uses one's complement arithmetic? Answer O CRC Checksum. Simple parity check. Two dimensional parity check. Multiple Choice (Total Point: 1.00) #5 cable is normally used for setting up a wired network in a single room with each computer having a dedicated link to a hub. Answer Twisted-pair Thin coaxial Fiber optic Thick coaxial Multiple Choice (Total Point: 1.00) #9 In an even parity scheme, what would be the correct parity bit for the binary string Answer 1 1101 0001 0 1101 0011 1 101 0001 1101 0001 1 Multiple Choice (Total Point: 1.00) #1 Circuit switching takes Answer data line physical network transport layer Multiple Choice (Total Point: 1.00) # 11 What is a host? Answer any device that has an IP address any device that has a MAC address any device with an IPv6 address any device at all Multiple Choice (Total Point: 1.00) # 10 How does an ARQ check work? Answer The sender resends the data if it does not receive confirmation after a certain amount of time The sender compares the sent data to the original and sees if an error occurred The receiver checks with the sender to find out whether the data was sent correctly The sender checks whether the receiver has received the data by performing a calculation on a check digit Multiple Choice (Total Point: 1.00) # 12 A Answer O has no filtering capability Repeater Switch Router Firewall Multiple Choice (Total Point: 1.00) # 13 Mr. John is a small businessman who runs Hardware. He has been experiencing problems with his small accounting department, which he depends on to provide sales reports. Mr. John wants to share information between his 7 computer stations and have on central printing area. What type of network would you recommend to Mr. John? Answer MAN LAN WAN SAN Multiple Choice (Total Point: 1.00) #7 Parity bit is Answer O O O O an error-detecting code based on a summation operation performed on the bits to be checked. a check bit appended to an array of binary digits to make the sum of all the binary digits. a code in which each expression conforms to specific rules of construction, so that f certain errors occur in an expression, the resulting expression will not conform to the rules of construction the ratio of the number of data units in error to the total number of data units Multiple Choice (Total Point: 1.00) #6 Refraction happens because Answer the light slows down in a material the light changes color in a material the light speeds up in a material the light stops in a material Multiple Choice (Total Point: 1.00) # 15 The checksum of 1111 and 1111 is Answer 0000 0001 0011 1111 Multiple Choice (Total Point: 1.00) # 14 Which error detection method consists of just one redundant bit per data unit? Answer O Simple parity check Two-dimensional parity check CRC Checksum Multiple Choice (Total Point: 1.00) # 8 Selective repeat ARQ is using sliding windows to control frames transmission. What is the window size for sender and receiver that is used to send frame consists of 4 bits? Answer O O Window size for sender is 8 frames and window size for receiver is 8 frames. Window size for sender is 4 frames and window size for receiver is 4 frames. Window size for sender is 17 frames and window size for receiver is always 1 frame Window size for sender is 8 frames and window size for receiver is always 1 frame.
