(006) What type of memory is non-volatile, considered permanent, and is also called firmware in reference to the data and instructions stored?
Correct Answer
B. Read-only memory (ROM).
Explanation
Read-only memory (ROM) is a type of memory that is non-volatile, meaning it retains its data even when the power is turned off. It is considered permanent because the data and instructions stored in ROM cannot be easily modified or erased. ROM is also sometimes referred to as firmware because it contains the software instructions that are permanently programmed during manufacturing.
15.
(006) This type of memory is blank and instructions can be placed on it permanently.
Correct Answer
C. Programmable read-only memory (PROM).
Explanation
PROM is a type of memory that allows instructions to be permanently placed on it. Unlike RAM, which can be read from and written to, PROM is non-volatile, meaning its contents are not erased when power is turned off. This makes PROM a suitable choice for storing permanent instructions that should not be changed or modified. ROM and CMOS are not the correct answers because ROM is not programmable and CMOS is not specifically designed for storing instructions.

This is commonly used in computer systems to gather information from hardware devices or to communicate with external systems. Signaling, processing, and multitasking are not accurate descriptions of this action.
20.
(006) What is defined as an asynchronous signal from a computer hardware device indicating the need for attention from a central processing unit (CPU) or a synchronous event indicating the need for a change in execution?
Correct Answer
D. Interrupt.
Explanation
An interrupt is a signal from a computer hardware device that indicates the need for attention from the CPU. It can be either asynchronous, meaning it can occur at any time, or synchronous, meaning it occurs at a specific time or event. Interrupts are used to interrupt the normal execution of a program and transfer control to a specific interrupt handler routine, which handles the event that triggered the interrupt. This allows the CPU to quickly respond to important events and prioritize tasks efficiently.
21.
(006) Which term describes that data is whole or complete?
Correct Answer
C. Data integrity.
Explanation
Data integrity refers to the accuracy, consistency, and reliability of data throughout its lifecycle. It ensures that data is whole or complete, without any errors or inconsistencies. Data integrity is crucial in maintaining the quality and trustworthiness of data, as it ensures that the data remains intact and reliable for its intended use.
22.
(006) Which is a very simple example of an error detecting code?
Correct Answer
B. Parity bit.
Explanation
A parity bit is a very simple example of an error detecting code. It is an extra bit added to a binary code to detect errors during transmission. The parity bit is set to 1 or 0 depending on the number of 1's in the data being transmitted. If the number of 1's is even, the parity bit is set to 0, and if the number of 1's is odd, the parity bit is set to 1. During transmission, the recipient can check the parity bit and compare it with the received data to determine if any errors occurred.
23.
(007) What operating system (OS) task ensures each process and application receives time to function and is used for real work as often as possible?

(010) What type of remote network provides a private tunnel through public clouds (the Internet)?
Correct Answer
A. Virtual private network (VPN).
Explanation
A virtual private network (VPN) is a type of remote network that provides a private tunnel through public clouds (the Internet). This allows users to securely access and transmit data over the Internet by encrypting the data and routing it through a remote server. VPNs are commonly used by businesses to connect remote offices or enable remote workers to access the company's network securely. They provide a secure and private connection, ensuring that data remains protected from unauthorized access or interception.
37.
(010) In a cable Internet, as the distance increases, the speed of the overall transfer rate of data...
Correct Answer
D. Stays the same.
Explanation
In a cable Internet, the speed of the overall transfer rate of data stays the same as the distance increases. This is because cable Internet uses coaxial or fiber optic cables to transmit data, which are not affected by distance in the same way as wireless connections. Unlike wireless signals, which can weaken and degrade over long distances, cable Internet maintains a consistent speed regardless of the distance between the user and the service provider. Therefore, the speed of data transfer remains constant regardless of the distance.
38.
(010) What form of remote network access is often the only choice for rural or remote areas?
Correct Answer
A. Dial-up.
Explanation
Dial-up is often the only choice for rural or remote areas because it uses existing telephone lines to establish a connection. This makes it accessible even in areas where other forms of network access, such as broadband or wireless, may not be available or reliable. Dial-up may have slower speeds compared to other options, but it remains a viable choice in areas with limited infrastructure.
39.
(010) What does Wi-Fi (wireless fidelity) use to carry network signals to the network access point?

(011) What software activates the actual transmission and receipt of data over the network?
Correct Answer
B. Network interface drivers.
Explanation
Network interface drivers are software programs that activate the actual transmission and receipt of data over the network. These drivers allow the network interface card (NIC) to communicate with the operating system and other devices on the network. Without the network interface drivers, the NIC would not be able to send or receive data, making it impossible to transmit information over the network.
44.
(011) Which of these is not defined by network protocols?
Correct Answer
C. Connector interfaces.
Explanation
Network protocols are responsible for defining the rules and procedures for communication within a network. They determine how data is transmitted, received, and processed. Packet sizes, signal timing, and whether acknowledgment is needed are all aspects that are defined by network protocols. However, connector interfaces are not defined by network protocols. Connector interfaces refer to the physical connectors used to connect devices to a network, such as Ethernet cables or USB ports. The specifications for these connectors are determined by hardware standards, not network protocols.
45.
(011) Which information is not required when configuring Transmission Control Protocol/Internet Protocol (TCP/IP)?
Correct Answer
B. Media access control (MAC) address.
Explanation
When configuring TCP/IP, the Media Access Control (MAC) address is not required. The MAC address is a unique identifier assigned to network interfaces, and it is used at the data link layer of the TCP/IP protocol stack. However, when configuring TCP/IP, the focus is on the network layer, which includes the IP address and the domain name system (DNS) server address. The IP address is essential for identifying devices on the network, and the DNS server address is necessary for translating domain names into IP addresses. Administrator access is also not directly related to TCP/IP configuration, as it pertains to user privileges and permissions.
46.
(012) What stores print jobs in a print queue until a printer becomes available?
Correct Answer
C. Print server.
Explanation
A print server is a device or software that stores print jobs in a print queue until a printer becomes available. It manages the printing process by receiving print requests from multiple computers and sending them to the appropriate printer. This allows for efficient printing and prevents print jobs from being lost or delayed if a printer is currently busy or offline.
47.
(013) Which is not a transmission medium for a wireless local area network?
Correct Answer
B. Fiber optics.
Explanation
Fiber optics is not a transmission medium for a wireless local area network because it requires physical cables to transmit data. Wireless local area networks, on the other hand, use radio waves to transmit data without the need for physical cables. Microwaves, radio waves, and light can all be used as transmission mediums for wireless local area networks as they can transmit data wirelessly.
