- C.
Cache.
- D.
CMOS.
Correct Answer
A. ROM.Explanation
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 its contents cannot be easily modified or erased. It is also referred to as firmware because it contains the data and instructions that are permanently stored and used by the computer system. Unlike RAM (Random Access Memory) and Cache, which are volatile and temporary, ROM provides long-term storage for essential system information. CMOS (Complementary Metal-Oxide-Semiconductor) is a type of technology used in computer chips and is not directly related to nonvolatile memory.Rate this question:

Bytes are the basic unit of storage in a computer, and the more bytes available, the more memory the computer can hold. This is because each byte represents a certain amount of data that can be stored and accessed by the computer's processor. Therefore, the more bytes available, the larger the memory capacity of the computer.Rate this question:

(003) What system executes the power-on self test?
- A.
The basic input/output system.
- B.
The CMOS.
- C.
The operating system.
- D.
The boot sector.
Correct Answer
A. The basic input/output system.Explanation
The power-on self test (POST) is a diagnostic process that checks the hardware components of a computer system to ensure they are functioning properly. The system responsible for executing this test is the basic input/output system (BIOS). The BIOS is firmware that is stored on a chip on the motherboard and is responsible for initializing and controlling the hardware components of the computer during the boot process. Therefore, the correct answer is the basic input/output system.Rate this question:

(003) What term refers to the process of launching the OS?
- A.
Bootstrap
- B.
Boot camp
- C.
Boot sector
- D.
Boot launcher
Correct Answer
A. BootstrapExplanation
Bootstrap refers to the process of launching the operating system. It is the initial set of instructions that are executed when a computer is turned on or restarted. The bootstrap process initializes the hardware, loads the operating system into memory, and starts the execution of the OS. It is responsible for setting up the system environment and preparing it for the user to interact with the computer. Therefore, bootstrap is the correct term that refers to the process of launching the OS.Rate this question:

(004) What are the types of memory?
- A.
Volatile & nonvolatile.
- B.
ROM & PROM
- C.
RAM & FLASH
- D.
Persistent & Non-Persistent
Correct Answer
A. Volatile & nonvolatile.Explanation
The correct answer is Volatile & nonvolatile. Volatile memory refers to temporary storage that loses its data when power is turned off, such as RAM. Nonvolatile memory, on the other hand, retains data even when power is turned off, such as ROM or flash memory. The other options mentioned, such as ROM & PROM and RAM & FLASH, are not accurate representations of the different types of memory.Rate this question:

(004) What is the type of memory that can be reprogrammed?
- A.
Erasable memory.
- B.
Non-Volatile memory.
- C.
ROM.
- D.
CMOS.
Correct Answer
A. Erasable memory.Explanation
Erasable memory refers to a type of memory that can be reprogrammed or erased, allowing for the storage of new data. This type of memory is often used in devices such as flash drives or EEPROM (Electrically Erasable Programmable Read-Only Memory) chips, where data can be modified or erased electronically. Non-volatile memory, on the other hand, retains data even when power is lost, but it may not necessarily be erasable or reprogrammable. ROM (Read-Only Memory) is a type of memory that cannot be modified or erased. CMOS (Complementary Metal-Oxide-Semiconductor) refers to a type of technology used in manufacturing integrated circuits, but it is not directly related to erasable memory.Rate this question:
