Local area networks are big enough to cover what area?
- A.
A single campus
- B.
A single house
- C.
A single department
- D.
A single office building
- E.
All of the above
Correct Answer
E. All of the aboveExplanation
Local area networks (LANs) are capable of covering a variety of areas, including a single campus, a single house, a single department, and a single office building. This means that LANs have the capacity to provide network connectivity and communication within these different environments. Therefore, the correct answer is "All of the above."Rate this question:

State whether this statement is TRUE or FALSE:Like the Internet, intranets are used to share information, but are protected from being accessed by a firewall (security software).
- A.
TRUE
- B.
FALSE
Correct Answer
A. TRUEExplanation
An intranet is designed to keep the local users safe from the worldwide intruders on the Internet.Rate this question:
-
- 7.
An advantage of using LAN is that ...?
- A.
The users are at risk for getting a virus.
- B.
All the resources can be shared with the others.
- C.
The network is inexpensive to maintain.
- D.
Well... there is no REAL advantage.
Correct Answer
B. All the resources can be shared with the others.Explanation
Using a local area network (LAN) provides the advantage of being able to share all the resources with others. This means that files, printers, and other devices can be easily accessed and used by multiple users on the network. This promotes collaboration and efficiency as it eliminates the need for each individual to have their own separate resources. Additionally, sharing resources on a LAN can also lead to cost savings as it reduces the need for duplicate equipment and allows for centralized management and maintenance.Rate this question:

Fibre Optic Cables send data not by ______, but by ______.
Correct Answer
electricity light
electricity lasersExplanation
Fibre Optic Cables send data not by electricity, but by light. The cables use pulses of light to transmit information over long distances. The light signals are generated by lasers, which convert electrical signals into light signals. These light signals travel through the fibre optic cables, which are made of thin strands of glass or plastic. The light signals bounce off the walls of the cables, allowing them to travel long distances without losing much of their strength. At the receiving end, the light signals are converted back into electrical signals for the data to be processed.Rate this question:
- 9.
This is the simplest wired transmission cable, since it has no aluminium mesh protection around the two core copper wires.
- A.
Fibre Optic Cable
- B.
Microwave Transmission
- C.
Twisted Pair Cable
- D.
Coaxial Cable
- E.
Ehmm... Wired Transmission??
Correct Answer
C. Twisted Pair CableExplanation
The correct answer is Twisted Pair Cable. This type of cable consists of two copper wires twisted together, without any aluminum mesh protection. It is considered the simplest wired transmission cable because of its basic construction.Rate this question:

Each of the nodes in a network connect through a device called a ___ , so that they can access shared resources.
Correct Answer
modem
network interface card
NICExplanation
Each of the nodes in a network connect through a device called a modem, network interface card (NIC), or NIC so that they can access shared resources. Both modems and network interface cards are commonly used to connect devices to a network. Modems are used to connect devices to the internet, while network interface cards are used to connect devices to a local area network (LAN). Both devices enable communication between nodes and allow them to access shared resources on the network.Rate this question:
- 11.
Microwave transmission is the technology that sends signals by way of a ____ path.
- A.
Geosynchronous orbit
- B.
Line-of-sight
- C.
Bluetooth
- D.
Radio signal
Correct Answer
B. Line-of-sightExplanation
This is a technology for transmitting digital and analog signals between two locations on a line of sight radio path, meaning the wireless link between two twoers (transmitter and receiver) within a visible, unobstructed, straight line distance of eath other.Rate this question:

- 12.
Communication within the computer, moderated by the processor is ____, happening in regular intervals.
- A.
Synchronical
- B.
Asynchronous
- C.
Asymmetrical
- D.
Synchronous
Correct Answer
D. SynchronousExplanation
Communication within the computer, moderated by the processor, is synchronous, happening in regular intervals. In synchronous communication, the sender and receiver are synchronized and operate at the same clock rate. This means that data is transmitted in a consistent and predictable manner, with both parties waiting for each other to complete a task before proceeding. This type of communication is commonly used in systems where timing and coordination are crucial, such as in real-time applications or when multiple devices need to be synchronized.Rate this question:
-
- 13.
Bluetooth is a wireless technology allowing devices to communicate with other devices performing with the same operating system. TRUE OR FALSE
- A.
TRUE
- B.
FALSE
Correct Answer
B. FALSEExplanation
The devices that use bluetooth operate within the same frequencies.Rate this question:

- 14.
Given that they use similar technology, the _____ is preferable to install than the ____ because it is cheaper and more secure.
Correct Answer
intranet, Internet
intranet, internetExplanation
The intranet is smaller that the Internet in physical size and scope, therefore it must be less expensive. It is defined as secure because of its use of a firewall to protect its users and the user data.Rate this question:
- 15.
What is a network?
- A.
A combination of devices working together
- B.
A set of computers linked together
- C.
A set of computers linked together to share resources
- D.
A combination of laptops and desktops connected via some wireless technology
Correct Answer
C. A set of computers linked together to share resourcesExplanation
While the other options describe aspects of networks, such as the devices working together, computers linked together, or a combination of laptops and desktops connected wirelessly, the essence of a network lies in the interconnection of computers to facilitate resource sharing and communication.Rate this question:
