TCP/IP (Transmission Control Protocol/Internet Protocol) is the core communications protocol for the Internet. It is responsible for breaking data into packets and reliably transmitting them across the network. Telnet and FTP are specific applications that use TCP/IP, while TLS (Transport Layer Security) is a protocol that provides secure communication over a network but is not the core communications protocol for the Internet.

Question 2

Where does TLS operate within TCP/IP?
A)between the Internet Layer and the Transport Layer
B)between the Transport Layer and the Application Layer
C)between the Network Interface Layer and the Transport Layer
D)between the Internet Layer and the Application Layer

Accepted Answer

TLS operates between the Transport Layer and the Application Layer. It is a protocol that operates above TCP and provides secure communication between applications.

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 (URL) system is used for identifying resources on the web and includes the protocol, domain name, and specific path to the resource. The Internet protocol (IP) addressing schema is used for assigning unique addresses to devices on a network. The assigned numbers and names (ANN) system is used for assigning numerical identifiers and names to protocols, services, and ports.

Question 4

Question 7

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

Each client added to the network does not necessarily increase the network's overall capacity and transmission speeds. It may increase the processing load on the server, which could potentially slow down the network.
