This simultaneous transfer of data through multiple lines is a characteristic feature of parallel ports.
10.
What term refers to the process of launching an operating system (OS)?
Correct Answer
A. Boot
Explanation
The term "boot" refers to the process of launching an operating system (OS). When a computer is turned on or restarted, it goes through a series of steps known as the boot process. During this process, the computer's hardware is initialized, and the OS is loaded into the computer's memory. The boot process starts with the computer's BIOS, which performs a power-on self-test (POST) and then locates and loads the OS from the computer's storage device, such as a hard drive or solid-state drive. Therefore, "boot" is the correct answer to the question.
11.

14.
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
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 referred to as firmware because it contains the essential instructions needed for the computer system to boot up and initialize hardware components. Unlike RAM, ROM is not directly accessible by the CPU and is used primarily for storing critical system software and firmware. Therefore, ROM is the correct answer to the question.
15.
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 is volatile and loses its data when power is turned off, PROM retains its information even when power is removed. ROM, on the other hand, is not programmable and contains instructions that are permanently embedded during manufacturing. CMOS is a type of technology used in integrated circuits and does not refer to a specific type of memory. Therefore, PROM is the correct answer as it meets the criteria of being programmable and retaining instructions permanently.

A spreadsheet is not considered a utility application because it is primarily used for organizing and analyzing data, performing calculations, and creating charts and graphs. Utility applications, on the other hand, are software programs that perform specific tasks to enhance the functionality of a computer system, such as optimizing performance, managing files, or providing security. Adobe Acrobat reader is used for viewing and editing PDF files, an antivirus program is used for protecting against malware and viruses, and WinZip is used for compressing and decompressing files.
30.
A hard disk is divided into how many byte sectors?
Correct Answer
C. 512
Explanation
A hard disk is divided into 512-byte sectors. This means that each sector on the hard disk can hold 512 bytes of data. The division of a hard disk into sectors allows for efficient storage and retrieval of data, as it allows the computer to easily locate and access specific sections of the disk. By dividing the disk into smaller sectors, it also helps to minimize data loss in case of errors or failures, as only a small portion of data would be affected in such cases.
31.
The first sector at the beginning of a hard drive is called the master
Correct Answer
D. Boot record
Explanation
The first sector at the beginning of a hard drive is called the boot record. This sector contains important information that is necessary for the computer to start up and load the operating system. It includes the initial instructions and code that the computer needs to access the operating system files and initiate the booting process. Without the boot record, the computer would not be able to start up properly.

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 cables to transmit data, which are designed to maintain signal strength over long distances. Unlike other types of Internet connections, such as DSL or fiber optic, cable Internet does not experience significant speed degradation with increased distance. Therefore, regardless of how far the data needs to travel, the speed of the overall transfer rate remains constant.
38.
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. In areas where broadband or wireless networks are not available or reliable, dial-up remains a viable option. Although it offers slower speeds compared to other forms of remote network access, it can still provide basic internet connectivity in areas where other options are limited or unavailable.
