What is a computer network?
Correct Answer
B. Interconnected computers on a system
Explanation
A computer network refers to a system where multiple computers are connected and able to communicate with each other. This allows for the sharing of resources, such as files and printers, and enables users to access information and services from other connected devices. Interconnected computers on a system accurately describes the concept of a computer network, as it emphasizes the connection and communication between computers within the system.

What does L.A.N Stand for
Correct Answer
C. Local Area Network
Explanation
LAN stands for Local Area Network. A Local Area Network is a network that connects computers and other devices within a limited area such as a home, office, or building. It allows for the sharing of resources and information between connected devices, such as printers, files, and internet access. LANs are commonly used in homes and businesses to facilitate communication and collaboration between devices and users in a localized environment.
3.
Which of the following is the smallest?
Correct Answer
B. LAN
Explanation
The correct answer is LAN because LAN stands for Local Area Network, which is the smallest network among the options given. LAN typically covers a small geographical area such as a home, office, or building, connecting devices within that limited area. MAN (Metropolitan Area Network) covers a larger area like a city, and WAN (Wide Area Network) covers the largest area, such as multiple cities or even countries. Therefore, LAN is the smallest network among the options provided.
4.
Which Network can be imagined as spreading across the entire world?
Correct Answer
C. WAN
Explanation
A Wide Area Network (WAN) can be imagined as spreading across the entire world because it is a network that connects multiple local area networks (LANs) and metropolitan area networks (MANs) over a large geographic area. Unlike LANs and MANs that are limited to a specific location or region, a WAN can span across countries and continents, providing connectivity on a global scale. Therefore, WAN is the correct answer as it best represents a network that covers the entire world.
5.
What is the minimum number of computers that can be on a network?
Correct Answer
B. 2
Explanation
A network can be formed with a minimum of two computers. This is because a network requires at least two devices to communicate and share resources. With only one computer, there is no other device to connect with, hence a network cannot be established. Therefore, the correct answer is 2.
6.
The computer that connects all the computers is called a node?
Correct Answer
B. False
Explanation
The Node is the computer it self and not the connecting system which is called a hub.
7.
__________________ is the rules and encoding specifications for sending data.
Correct Answer
protocol
Protocol
Explanation
The term "protocol" refers to the set of rules and encoding specifications that are used for sending data. These rules and specifications ensure that data is transmitted and received correctly between different devices or systems. By following the protocol, devices can communicate effectively and understand each other's messages. The use of a standardized protocol allows for interoperability and seamless data exchange between different systems.
8.
The _________________ communication mode has the keyboard communicating with the computer as an example.
Correct Answer
simplex
SIMPLEX
Simplex
Explanation
The term "simplex" refers to a one-way communication mode where information flows in only one direction. In this mode, the keyboard is used to input data into the computer, but there is no feedback or response from the computer to the keyboard. This is a good example of simplex communication because the keyboard is only transmitting data to the computer without receiving any information back. The variations in capitalization (SIMPLEX, Simplex) do not affect the meaning of the term.
9.
The _____________________ communication mode is like a road under construction.
Correct Answer
Half Duplex
half duplex
HALF DUPLEX
Explanation
The comparison made in the question suggests that the communication mode being referred to is similar to a road under construction. This implies that the communication mode is not fully functional or efficient, just like a road that is being worked on and is not yet fully operational. The term "half duplex" refers to a communication mode where data can be transmitted in both directions, but not simultaneously. This fits the description given in the question, making it the correct answer.
