Question 1

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 (TCP).
C)packet switching.
D)the File Transfer Protocol (FT

Accepted Answer

Packet switching is a process of breaking down messages into small units called packets, sending them through different communication paths, and reassembling them at the destination point. This technique is widely used in computer networks to transmit data efficiently. Routing and TCP are related to packet switching, but they are not the exact process of breaking down and reassembling messages. FTP is a protocol used for transferring files, not specifically for breaking down and transmitting messages.

Question 2

________ is used to allow remote login on another computer.
A)Telnet
B)FTP
C)HTTP
D)SSL

Accepted Answer

Telnet is a protocol used to establish a connection with a remote computer over a network, allowing users to access the command-line interface of the remote host as if they were physically present at the machine. FTP is used for file transfer, HTTP is used for web browsing, and SSL is used for secure communication over the internet, but none of them are specifically designed for remote login.

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 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 used to specify the address of a web page, the internet protocol addressing schema (IP address) is a unique identifier for every device connected to the internet, while the assigned numbers and names system is used by the Internet Assigned Numbers Authority (IANA) to assign unique values for protocols and services.

B)FTP
C)TCP/IP
D)packet switching

Accepted Answer

FTP (File Transfer Protocol) is a protocol used for transferring files between servers and clients, it is a specific application used on top of the basic technological foundations of the Internet. The other three options, client/server computing, TCP/IP, and packet switching are foundational technologies that enable the Internet to function.

Question 7

Which of the following statements about cloud computing is not true?
A)A public cloud is typically used by companies with stringent privacy and security requirements.
B)Dropbox is an example of a public cloud.
C)Hybrid clouds offer both public and private cloud options.
D)A private cloud hosted internally or externally.

Accepted Answer

A public cloud is typically used by companies with less stringent privacy and security requirements, as the data is stored on shared infrastructure with other organizations. Private clouds, on the other hand, are used by companies with more stringent security and privacy requirements as they offer more control over the data and infrastructure.

Question 8

________ is a utility program that allows you to check the connection between your client and a TCP/IP network.
A)Ping
B)Telnet
C)Tracert
D)Finger

Accepted Answer

Ping is the utility program that tests the connection between a client and a TCP/IP network. It sends a small packet of data to the network address and waits for a reply to confirm the connection. Telnet is a program that allows remote control of a server or device through a virtual terminal connection. Tracert is a program that traces the route of packets across a network and provides information on each hop. Finger is a program that retrieves information about a user on a remote server, such as their username or login status.

Question 9

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 the necessary addressing information to the packets so that they can be properly routed over the network. It is also responsible for breaking data into packets and reassembling them at the receiving end.

Question 10

Which of the following are specialized computers that transmit message parcels along available Internet communication paths and on to their destinations?
A)routers
B)Web servers
C)IP servers
D)packet servers

Question 13

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 the network does not increase the network's overall capacity and transmission speeds. It may actually slow down the network if there are too many clients and not enough server capacity to handle the requests.

Question 14

Which of the following is the core communications protocol for the Internet?
A)Telnet
B)FTP
C)TCP/IP
D)TLS

Accepted Answer

TCP/IP is the core communications protocol for the Internet, responsible for establishing connectivity between devices and for ensuring data is transmitted correctly between them. Telnet and FTP are protocols that allow for remote access and file transfer, respectively, while TLS is a security protocol for data encryption. However, none of these protocols are as pivotal to the functioning of the Internet as TCP/IP.
