Chapter 3
A user is viewing an HTML document located on a web server. What protocol segments the messages and manages the segments in the individual conversation between the web server and the web client?
TCP
What is the purpose of the FCS field in a frame?
to determine if errors occurred in the transmission and reception The FCS field in a frame is used to detect any errors in the transmission and receipt of a frame.
Which statement is correct about multimode fiber?
C-SC patch cords are used with multimode fiber cables.
What are two characteristics of 802.11 wireless networks?
-They use CSMA/CA technology. -Collisions can exist in the networks.
Which PDU format is used when bits are received from the network medium by the NIC of a host?
frame
Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. Based on the configured network, what IP address would PC1 and PC2 use as their default gateway?
192.168.1.1 he default gateway is a router on a LAN segment that is responsible for sending a packet generated by the host to a remote destination.
Which IEEE standard enables a wireless NIC to connect to a wireless AP that is made by a different manufacturer?
802.11 standard defines how wireless LANs operate
What is one main characteristic of the data link layer?
It shields the upper layer protocol from being aware of the physical medium to be used in the communication. The data link layer receives packets from and directs packets to an upper layer protocol. As a consequence, the upper layer protocol does not have to worry about the media that the communication will use.
Which statement describes signaling at the physical layer?
Sending the signals asynchronously means that they are transmitted without a clock signal.
TCP/IP and OSI models
The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.
If the default gateway is configured incorrectly on the host, what is the impact on communications?
The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks.
As data travels on the media in a stream of 1s and 0s how does a receiving node identify the beginning and end of a frame?
The transmitting node inserts start and stop bits into the frame. When data travels on the media, it is converted into a stream of 1s and 0s.
What is wrong with the displayed termination?
The untwisted length of each wire is too long.
Why are two strands of fiber used for a single fiber optic connection?
They allow for full-duplex connectivity. Light can only travel in one direction down a single strand of fiber. In order to allow for full-duplex communication two strands of fiber must be connected between each device.
user sends an HTTP request to a web server on a remote network. During encapsulation for this request, what information is added to the address field of a frame to indicate the destination?
he MAC address of the default gateway
Bandwidth
indicates the capacity of a medium to carry data and it is typically measured in kilobits per second (kb/s) or megabits per second (Mb/s).
What are proprietary protocols?
protocols developed by organizations who have control over their
