1.
One
purpose of a network is_________________
Correct Answer
A. Sharing software
Explanation
A network allows users to share software applications across multiple devices or computers. This enables collaboration and efficiency as users can access and use the same software simultaneously. By sharing software, users can avoid the need for individual installations and updates on each device, saving time and resources. Additionally, sharing software allows for centralized management and control, ensuring that all users have access to the latest versions and updates.
2.
Which
of the following is NOT used to facilitate communication on the network?
Correct Answer
D. Printing
Explanation
Printing is not used to facilitate communication on the network because it involves physical output of documents or files, rather than transmitting information electronically. E-mail, instant messaging, and chat rooms are all methods of electronic communication that allow individuals to send messages, files, or have real-time conversations over a network. However, printing requires a physical printer and paper to produce hard copies of documents, which is not directly related to network communication.
3.
What
is a network?
Correct Answer
B. A collection of computers and devices connected by communication channels
Explanation
A network refers to a collection of computers and devices that are interconnected through communication channels. These communication channels allow the devices to share information and resources with each other. This can include sharing files, printers, and internet connections. By connecting these devices, users can communicate and collaborate efficiently, making it easier to share information and work together.
4.
Which of the
following allows users to connected to a network and allows the users access
application programs?
Correct Answer
B. Sharing software
Explanation
Sharing software allows users to connect to a network and access application programs. This means that users can share and utilize software applications that are installed on a central server or computer, allowing them to access and use the programs remotely. This is different from sharing files, data, and information, which refers to the sharing of specific files or data between users. Sharing hardware refers to sharing physical devices, such as printers or scanners, while communicating refers to the act of exchanging information or messages between users.
5.
The
smallest type of network is _________________
Correct Answer
D. PAN
Explanation
A PAN (Personal Area Network) is the smallest type of network. It is a network that connects devices within a short range, typically within a person's immediate surroundings such as a home or office. PANs are often created using technologies like Bluetooth or Wi-Fi, allowing devices such as smartphones, laptops, and wearable devices to communicate with each other.
6.
The largest type of network is
Correct Answer
D. WAN
Explanation
A Wide Area Network (WAN) is the largest type of network as it covers a large geographical area, typically spanning multiple cities or even countries. It connects multiple Local Area Networks (LANs) and Metropolitan Area Networks (MANs) together, allowing for communication and data exchange over long distances. Unlike LANs and MANs which are limited to smaller areas, WANs can provide connectivity on a global scale, making it the largest type of network.
7.
PAN
is used in which communication technology?
Correct Answer
A. Blue tooth
Explanation
Bluetooth technology is a wireless communication technology that allows devices to connect and exchange data over short distances. It uses radio waves to transmit and receive data between devices. PAN (Personal Area Network) refers to a network that connects devices within a small area, typically within a person's immediate vicinity. Bluetooth is commonly used in PANs to connect devices such as smartphones, tablets, laptops, and headphones. Therefore, the correct answer is Bluetooth.
8.
Which
of the following is NOT a type of Wireless Media?
Correct Answer
D. Fiber Optic Cable
Explanation
Fiber Optic Cable is not a type of wireless media because it uses light signals to transmit data instead of radio waves or electromagnetic signals. Bluetooth, Satellite, and Microwave are all examples of wireless media because they rely on wireless communication technology to transmit data over long distances without the need for physical cables.
9.
Which
of the following is a type of Physical Media?
Correct Answer
D. Fiber Optic Cable
Explanation
Fiber Optic Cable is a type of Physical Media because it is a medium through which data is transmitted in the form of light pulses. It consists of thin strands of glass or plastic that can carry large amounts of data over long distances at high speeds. Unlike other options listed, such as Bluetooth, Satellite, and Microwave, which are wireless communication technologies, Fiber Optic Cable is a physical medium that requires a physical connection for data transmission.
10.
A ______________ is
type of cable that consists of two Independently insulated wires twisted around
one another.
Correct Answer
A. Coaxial Cable
Explanation
A coaxial cable is a type of cable that consists of two independently insulated wires twisted around one another. This design helps to minimize interference and signal loss, making it ideal for transmitting high-frequency signals. The inner conductor carries the signal, while the outer conductor serves as a shield to protect the signal from external interference. Coaxial cables are commonly used in telecommunications, cable television, and computer networks.
