A) routers
B) Web servers
C) IP servers
D) packet servers

Accepted Answer

Routers are specialized computers that transmit message parcels along available Internet communication paths and on to their destinations. Web servers are computers that store and serve website content. IP servers and packet servers are not commonly used terms in relation to internet communication.

Question 3

The ________ allows a natural language expression,such as Google.com to represent a numeric IP address.
A) uniform resource locator system
B) Internet protocol addressing schema
C) domain name system
D) assigned numbers and names (ANN) system

Accepted Answer

The domain name system (DNS) allows a natural language expression, such as Google.com, to represent a numeric IP address. The uniform resource locator system (URL) is a subset of DNS, which specifies the exact location of a resource on the internet. The Internet protocol addressing schema is the system used for IP addressing and routing of data packets. The assigned numbers and names (ANN) system is the central repository for protocol and port numbers used in many internet protocols.

Question 4

The process of slicing digital messages into parcels,sending them along different communication paths as they become available,and reassembling them at the destination point is called:
A) routing.
B) the Transmission Control Protocol.
C) packet switching.
D) the File Transfer Protocol.

Accepted Answer

This process is called packet switching, where a message is divided into smaller packets and sent through different communication paths before being reassembled at the destination point. Routing is a part of this process, but it only pertains to the selection of the best path for the packets. TCP and FTP are specific protocols used in data transmission, but they do not encompass the entire process of packet switching.

Question 5

Which of the following is not an advantage of client/server computing over centralized mainframe computing?
A) It is easy to expand capacity by adding servers and clients.
B) Each client added to the network increases the network's overall capacity and transmission speeds.
C) Client/server networks are less vulnerable, in part because the processing load is balanced over many powerful smaller computers rather than concentrated in a single huge computer.
D) There is less risk that a system will completely malfunction because backup or mirror servers can pick up the slack if one server goes down.

Accepted Answer

Adding clients to a client/server network does not necessarily increase the overall capacity and transmission speeds of the network. It depends on factors such as the network architecture, server capacity, and network bandwidth.

Question 6

The Internet Layer of TCP/IP is responsible for which of the following?
A) placing packets on and receiving them from the network medium
B) addressing, packaging, and routing messages
C) providing communication with the application by acknowledging and sequencing the packets to and from the application
D) providing a variety of applications with the ability to access the services of the lower layers

Accepted Answer

The Internet Layer of TCP/IP is responsible for addressing, packaging, and routing messages. It is responsible for adding IP addresses to packets and ensuring that packets are correctly routed to their destination. Other layers are responsible for other tasks, such as placing packets on the network medium (Data Link Layer) and communicating with applications (Transport Layer). Option A is more specifically the responsibility of the Data Link Layer, while option C is more specifically the responsibility of the Transport Layer. Option D is not a responsibility of the Internet Layer.

Question 12

The address used by a browser to identify the location of content on the Web is called:
A) a domain name.
B) a uniform resource locator.
C) an IP address.
D) a file path.

Accepted Answer

The address used by a browser to identify the location of content on the Web is called a uniform resource locator (URL). A domain name is part of a URL, but it is not the entire address. An IP address is another type of address used to identify computers on a network, but it is not typically used by browsers to locate Web content. A file path is another type of address used to locate content on a computer's file system, but it is not used by browsers to locate Web content.
