In your building, all the computers on the third floor are connected to a switch in a telecommunications closet on the third floor. From this switch, a single fiber optic cable runs down to a switch on the first floor. Three servers and a router connect to this switch. When messages from different connections (conversations) are mixed on the single cable that connects the first and thind floors, this is called: Multiplexing Framing Routing Which of the following is the shortest network link that would be considered a WAN link? The UTP cable I installed in my house that connects the PC in the upstairs bedroom to a switch in the basement.

In a certain network, the source and destination hosts are separated by nine routers that interconnect ten different subnets. When an application on the source host transmits a message to an application on the destination host, how many different data link layer frames will travel through the network? One Two Nine Ten In a certain network, the source and destination hosts are separated by nine routers that interconneet ten differe. subnets. When an application on the source host transmits a message to an application on the destination host, how many different data link layer frames will travel through the network? One Two Nine Ten Five switches separate two hosts on a network. How many physical links are there between the two hosts? (You may want to draw a diagram of this.) Six Five Two One In 1962, AT \&T introduced a modem that transmitted over normal phone lines at 300 bpa. To represent a 0 , a tone of 1070Hz was played. To represent a I, a tone of 1270Hz was played. What is the band rate of this modem? 1070 300 1270 150 Which of the following lerms indicales the weakening of a signal as is passes through media? Propagation Interference Takking Points Attenuation You deeide to move your eomputer from the den to your bedroom. However, when you put the eomputer in your bedroom, the wireless connection to the internet goes down every time your brother turns on his blow dryer. The blow dryer didn't affect the connection when the computer was in the den. Which of the following best describes the reason why the connection works in the den but not in your room?

Aecause your connection is "Ethernet," It transmits through an invisible layer of gas that is destroyed in your bedroom when your brother's hairspray is heated by his blow dryer. You need to kick your brother out of the house. That mullet-head isn't getting a job any lime soon. Light waves can't transmit through walls
