Terms in this set (59)A video-streaming Web site uses 32-bit integers to count the number of times each video has been played. In anticipation of some videos being played more times than can be represented with 32 bits, the Web site is planning to change to 64-bit integers for the counter.

A line between two computers indicates that the computers can communicate directly with each other, Any information sent between two computers that are not directly connected must go through at least one other computer. For example, information can be sent directly between computers A and B, but information sent between computers A and C must go through other computers. 3 Which of the
following statements about security in the network is true? II only Why was IPv6 introduced as the new version of the Internet Protocol? With only 32 bit IP addresses, the older version could not support the large number of devices connecting to the internet.

Two computers are built by different manufacturers. One is running a Web server and the other is running a Web browser. Which of the following best describes the ability of the two computers to communicate with each other across the Internet?

TCP/IP are the only protocols necessary to send and receive information over the Internet. Which of the following statements about packets is FALSE? The packet does not contain information about the sender's IP address. Many networks are set up using a hierarchical architecture to create a "backbone" network. In this system, several connected routers act as the backbone, and many smaller LANs are connected to the backbone.

Which of the following most makes this possible: Hierarchical DNS A new device is given as IP address and added to a network so that it can access the Internet. Large amounts of files are uploaded and downloaded on this new device, but other users who were already online do not experience any difference in performance. Which of the following enables this phenomenon? Redundant routers The figure below represents a network of physically linked computers labeled A though F. Computers with a line between them can communicate directly to each other and if two computers do not have a line connecting them, they must go through at least one other computer to communicate
with each other. 2 Which of the following statements is TRUE regarding Internet protocols? All of the above are false. Which of the following is a primary reason for the use of open protocols on the Internet? Open protocols provide a way to standardize data transmission between different devices. Choose the correct answer. II only Each packet being routed around the internet contains header information about the packet itself, and it also contains part of the file being transferred.
