Question 1

The term ____ refers to the wire cabling, such as coaxial or the more commonly used twisted-pair, that form the connections in most networks.
A) media
B) EMI
C) server
D) node

Accepted Answer

The term "media" refers to the physical cables or wireless signals that are used to transmit data in a network. EMI (electromagnetic interference) refers to a type of signal distortion that can affect network communication, but it is not directly related to the wiring or cabling used. A server is a type of computer that provides resources or services to other devices on a network, while a node is any device that is connected to a network.

Question 2

The seven layers of the OSI reference model communicate with one another via ____ communication.
A) multicast
B) logical
C) peer
D) unicast

Accepted Answer

The seven layers of the OSI reference model communicate with one another via peer-to-peer communication, which means that each layer communicates with the corresponding layer on the other device. This ensures that data is transmitted and received correctly without any alteration or loss. Multicast and unicast refer to specific types of addressing, while logical communication is a general term that does not accurately describe the communication between layers in the OSI model.

Question 3

Computers must use a common protocol to communicate properly.

Accepted Answer

Computers need to use a common language or protocol to communicate with one another. Without a common protocol, they would not understand each other's messages.

Question 4

An intranet is a private network that is only accessible to employees within a company or organization. It is separate from the Internet and is used to share information and resources within the company. LAN (Local Area Network) is a type of computer network that covers a small geographical area within a single building or office. SAN (Storage Area Network) is a specialized high-speed network that provides block-level access to data storage. An extranet is a private network that allows access to authorized external users, such as suppliers or customers.

Question 11

In 1954, the International Organization for Standardization (ISO) presented the Open Systems Interconnection (OSI) model.

Accepted Answer

The OSI model was developed by the International Organization for Standardization (ISO) in 1978, not in 1954.

Question 12

A(n) ____ address is a 48-bit address represented as a 12-digit hexadecimal number given to each network card during production.
A) CRC
B) RPC
C) LLC
D) MAC

Accepted Answer

The MAC address (Media Access Control address) is a unique identifier assigned to network interfaces for communications on the physical network segment. It is a 48-bit address represented as a 12-digit hexadecimal number given to each network card during production. CRC (Cyclic Redundancy Check), RPC (Remote Procedure Call), and LLC (Logical Link Control) are all different networking acronyms and not relevant to describing the MAC address.

Question 13

Because the MAC address is added during the manufacturing process, it is a permanent marking. For this reason, the address is also known as a ____.
A) NIC
B) BIA
C) CRC
D) CSMA/CD

Accepted Answer

The permanent MAC address is also known as the BIA (Burned-In Address). NIC (Network Interface Card) refers to the physical hardware that allows a computer to connect to a network. CRC (Cyclic Redundancy Check) is a method used for error detection in data transmission. CSMA/CD (Carrier Sense Multiple Access with Collision Detection) is a networking protocol used in Ethernet networks.

Question 14

Many LANs and WANs contain several segments. Dividing a network into segments reduces performance.

Accepted Answer

Dividing a network into segments can actually improve performance by reducing congestion and improving network efficiency.

Question 15

The ____ is information that is used to determine whether data was corrupted during transmission.
A) LLC
B) CRC
C) MAC
D) RPC

Accepted Answer

CRC (Cyclic Redundancy Check) is used to verify the integrity of data during transmission. It involves adding a checksum to the data that is sent, and the receiver checks to make sure that the data received matches the checksum. If there is a discrepancy, the data is considered to be corrupted. The other options, LLC (Logical Link Control), MAC (Media Access Control), and RPC (Remote Procedure Call), do not specifically address data corruption during transmission.

Question 16
