Question 1

Computer users must load instructions onto ROM the first time they use a new computer.

Accepted Answer

Instructions are pre-loaded onto ROM by the manufacturer and are not required to be loaded by the user.

Question 2

RAM temporarily holds data and instructions about to be processed; if the computer's power goes off,everything in RAM is lost.

Accepted Answer

RAM (Random Access Memory) is a type of volatile memory that temporarily stores data and instructions that the CPU (Central Processing Unit) currently needs to access. When the computer's power is turned off, all data and instructions stored in RAM are lost because RAM requires a constant flow of electricity to keep its contents intact.

Question 3

In computer systems,"expansion" and "upgrading" mean the same thing.

Accepted Answer

Expansion refers to adding new hardware or components to a system, whereas upgrading generally refers to replacing existing hardware or components with newer or better ones. While these two concepts are related, they are not interchangeable.

Question 4

Buses transmit bits within the CPU and between the CPU and other components of the motherboard.The number of bits that the bus can handle at one time is the computer's word size.

Accepted Answer

This statement is true. Buses are used to transmit data within the computer's hardware and the capacity of the bus is determined by the computer's word size, which is the number of bits that can be processed at one time.

Question 5

Cache memory uses some free hard-disk space to extend the capacity of RAM.

Accepted Answer

Cache memory is a type of high-speed memory that stores frequently used data and instructions for quick access by the CPU. It is typically built into the CPU or located on a separate chip close to it. Cache memory does not extend the capacity of RAM; rather, it helps to improve the performance of the system by reducing the time taken to access frequently used data.

Question 6

Common expansion cards are graphics card,sound card,and network card.

Accepted Answer

Graphics card, sound card, and network card are common expansion cards used in computers.

Question 7

RAM is read-only memory.

Accepted Answer

RAM stands for random-access memory which is a type of computer memory that allows data to be read and written. It is not read-only memory.

Question 8

Virtual memory also speeds up a computer's operations by extending RAM onto some free hard-disk space.

Accepted Answer

Virtual memory allows the computer to use some space on the hard disk as an extension of physical RAM, thereby improving the computer's performance.

Question 9

Cache is upgradable.

Accepted Answer

The answer of Cache is upgradable....

Question 10

A computer processor handles bits in chunks called word size-for example,a 32-bit word size transfers data within each microprocessor chip in 32-bit,or 4-byte,chunks.A computer that uses 64-bit word size is faster than a 32-bit computer.

Accepted Answer

A 64-bit computer can handle larger amounts of data at once and perform operations more quickly than a 32-bit computer.

Question 11

Most modern microcomputers need more than 2 gigabytes of RAM to run efficiently.

Accepted Answer

As software and applications become more demanding, the need for more RAM increases. Most modern microcomputers require at least 4 gigabytes or more to run efficiently, with some requiring even more depending on the workload.

Question 12

The computer determines what information in RAM is being used frequently and copies that information into cache,a special memory area built into the CPU that can be accessed quickly and thus speeds up processing.

Accepted Answer

This statement is true.

Question 13

Processing chips run faster than RAM chips do,so to help maintain efficiency,faster memory areas are built into the processor chips to speed up processing by bridging the gap between RAM and the CPU.

Accepted Answer

Processing chips do run faster than RAM chips, and there are built-in faster memory areas in the processor to bridge the gap between RAM and CPU for better efficiency.

Question 14

For a computer to communicate wirelessly,it needs a wireless network card attached to the motherboard via an extension slot.

Accepted Answer

A wireless network card is required for wireless communication, but it can also be integrated directly onto the motherboard in some cases.

Question 15

Many PCs offer open architecture,whereas most Apple computers are closed architecture.

Accepted Answer

Open architecture refers to a system that allows third-party components such as expansion cards, memory modules, or peripherals to be added or upgraded easily. Most PCs offer open architecture, while most Apple computers only allow upgrades and modifications through authorized service providers.

Question 16

Expansions bus lines connect the CPU with expansion slots and peripheral devices.

Accepted Answer

Expansions bus lines are used to connect the CPU with expansion slots and peripheral devices, allowing the system to expand its functionality and capabilities.

Question 17

RAM is primary storage and is volatile.

Accepted Answer

RAM (Random Access Memory) is primary storage and is volatile, which means that it loses its data when the power is turned off or interrupted.

Question 18

Buses are high-speed storage areas that temporarily store data during processing.

Accepted Answer

Buses are communication systems that transfer data between components inside a computer, or between computers, not temporary storage areas.

Question 19

Regarding a ROM chip,"read-only" means that the CPU can retrieve programs (such as BIOS)from the ROM chip but cannot modify or add to those programs.

Accepted Answer

"Read-only" means that the content cannot be altered, only read. Therefore, the CPU can retrieve programs from the ROM chip but it cannot modify or add to them.

Question 20

If a chip can be erased and reprogrammed more than once,it is a ROM memory chip.

Accepted Answer

A ROM (Read-Only Memory) chip can only be programmed once, hence the name "read-only." Therefore, if a chip can be erased and reprogrammed multiple times, it is not a ROM chip.
