What type of memory is nonvolatile, considered permanent, and is also called firmware in reference to the data and instructions stored?
- A.
RAM
- B.
ROM
- C.
Cache
- D.
CMOS
Correct Answer
B. ROMExplanation
ROM stands for Read-Only Memory. It is a type of memory that is nonvolatile, meaning it retains its data even when the power is turned off. ROM is considered permanent because the data and instructions stored in it cannot be modified or erased by normal computer operations. It is also called firmware because it contains the essential instructions that are permanently programmed during manufacturing and cannot be changed by the user. Therefore, ROM is the correct answer for the given question.Rate this question:

- B.
RAM
- C.
CMOS
- D.
PROM
Correct Answer
D. PROMExplanation
PROM stands for Programmable Read-Only Memory. It is a type of memory that can be programmed once by the manufacturer or user and the instructions placed on it are permanent. Unlike RAM (Random Access Memory) which is volatile and loses its data when the power is turned off, PROM retains its data even without power. CMOS (Complementary Metal-Oxide-Semiconductor) is a type of technology used in integrated circuits, not a type of memory. Therefore, PROM is the correct answer.Rate this question:

Which type of memory is used to duplicate frequently used information stored elsewhere or computed earlier, because the original data is time consuming to retrieve or to compute?
- A.
RAM
- B.
ROM
- C.
Buffer
- D.
Cache
Correct Answer
D. CacheExplanation
Cache memory is used to duplicate frequently used information stored elsewhere or computed earlier, because the original data is time-consuming to retrieve or compute. Cache memory is a small, high-speed memory that is located closer to the CPU than the main memory (RAM). It stores copies of frequently accessed data from the main memory, allowing the CPU to access it quickly. By duplicating this data in cache memory, the CPU can avoid the delay of retrieving it from the main memory, resulting in improved system performance.Rate this question:

Reading and storing a document on a hard disk or some other storage medium for processing at a more convenient time is called:
- A.
A driver
- B.
Spooling
- C.
An interrupt
- D.
A print queue
Correct Answer
B. SpoolingExplanation
Spooling refers to the process of reading and storing a document on a storage medium, such as a hard disk, for later processing. This allows the computer to handle multiple tasks simultaneously and improves efficiency by separating the input and output processes. By spooling, the document is temporarily stored in a queue, which can be accessed by the appropriate device or program when it is ready to process the document. This helps to prevent delays and ensures smooth execution of tasks.Rate this question:

A spooled print job can be several times larger than the printed document size because of the conversion to the:
- A.
Printer's language
- B.
Driver's language
- C.
Processor's language
- D.
Print server's language
Correct Answer
A. Printer's languageExplanation
When a print job is spooled, it is converted into the language that the printer understands, which is known as the printer's language. This language is specific to the printer model and allows the printer to accurately reproduce the document. The size of the spooled print job can be larger than the original document size because the printer's language may include additional information such as fonts, graphics, and formatting instructions that are necessary for the printer to accurately reproduce the document.Rate this question:

Hypertext transfer protocol
- B.
Printer front panel controls
- C.
Hewlett Packard Jetadmin
- D.
Telnet
Correct Answer
A. Hypertext transfer protocolExplanation
Printer hardware configuration via the web is done through the hypertext transfer protocol (HTTP). HTTP is the protocol used for transmitting hypertext over the internet, allowing users to access and interact with web pages. In the context of printer hardware configuration, HTTP enables users to access the printer's web interface through a web browser, where they can make changes to settings, configure options, and manage the printer remotely. This method provides a convenient and user-friendly way to configure printer hardware settings without the need for physical access to the printer or using specialized software.Rate this question:

- D.
TCP/IP printing
Correct Answer
D. TCP/IP printingExplanation
TCP/IP printing is a type of printer software configuration option that requires a new port to be created. This is because TCP/IP printing allows for printing over a network using the TCP/IP protocol. In order to establish a connection and send print jobs to the printer, a new port needs to be created to facilitate the communication between the computer and the printer. This ensures that the print jobs are properly transmitted and received by the printer over the TCP/IP network.Rate this question:

What is installed on a computer to act as the interface between the computer and network?
- A.
A NIC
- B.
Ethernet
- C.
Transceiver
- D.
Coaxial cable
Correct Answer
A. A NICExplanation
A NIC (Network Interface Card) is installed on a computer to act as the interface between the computer and the network. It allows the computer to connect to a network, sending and receiving data packets. The NIC converts the data from the computer into a format that can be transmitted over the network, and vice versa. It also handles the communication protocols required for network connectivity. Ethernet and transceiver are components related to network connectivity, but they are not specifically responsible for acting as the interface between the computer and the network. Coaxial cable is a type of cable used for network connections, but it is not the component that acts as the interface.Rate this question:

OUI address
- D.
SAS address
Correct Answer
A. MAC addressExplanation
A network interface card (NIC) provides a unique identification number known as a MAC address to a personal computer. MAC stands for Media Access Control, and it is a hardware address assigned to the NIC by the manufacturer. The MAC address is used to identify the NIC on a network and is essential for communication between devices. It consists of six groups of two hexadecimal digits separated by colons or hyphens. The MAC address ensures that each device on a network has a distinct identifier, allowing for efficient and accurate data transmission.Rate this question:
