Computer Memory and storage devices MCQs

RAM stands for Random Access Memory, which is used for temporary data storage and quick access by the CPU.

ROM (Read-Only Memory) is non-volatile memory that retains data even when the power is turned off.

Cache memory stores frequently accessed data for faster retrieval by the CPU, improving processing speed.

ROM (Read-Only Memory) is used for long-term data storage and program storage.

Virtual memory expands available RAM by using a portion of the hard drive to temporarily store data.

RAM (Random Access Memory) is a volatile type of memory, meaning it loses data when the power is turned off.

A hard drive is used for long-term data storage in a computer system.

The primary difference is that RAM is volatile (loses data when powered off), while ROM is non-volatile (retains data when powered off).

Solid-State Drives (SSDs) have no moving parts and use NAND flash memory for storage.

The read/write head in a hard drive is responsible for reading and writing data to and from the hard drive's platters.

Optical drives like CD/DVD drives are used to read and write data to optical discs.

Magnetic tape is known for high data transfer rates and durability but is less common in consumer computers.

A cache hit in cache memory refers to a successful memory access from the cache, which results in faster data retrieval.

The cache controller controls the flow of data between the CPU and cache memory.

Solid-State Drives (SSDs) have the fastest data access times among the options listed.

A cache miss in cache memory refers to a failure in fetching data from the cache, resulting in longer access times.

A CD-ROM is primarily used to read data from a compact disc.

Hard drives use magnetically coated platters for data storage.

The BIOS chip initializes hardware components and starts the boot process when a computer is powered on.

USB Flash Drives are often used for portable data storage and have a USB interface.

The CMOS battery maintains the computer's real-time clock and BIOS settings.

RAID configurations are used to improve data redundancy and performance by combining multiple disks.

Hard drives typically have the highest storage capacity among the options listed.

The memory controller controls the flow of data between the CPU and memory.

Hard drives use magnetic heads to read and write data to rotating platters.

ROM (Read-Only Memory) is used to store the computer's firmware and BIOS.

RAM (Random Access Memory) is used to temporarily store and execute program instructions and data.

Solid-State Drives (SSDs) have no moving parts and are known for their shock resistance.

The CPU cache stores frequently accessed data for faster retrieval by the CPU, improving processing speed.

Optical drives use optical discs for data storage and retrieval.

ROM (Read-Only Memory) stores the computer's firmware and BIOS and is non-volatile.

Solid-State Drives (SSDs) are known for fast data access times but may have lower storage capacity compared to hard drives.

The pagefile expands available RAM by using a portion of the hard drive for temporary data storage.

The cache controller manages memory storage and access in a computer system.

USB flash drives provide portable data storage with a USB interface.

RAM (Random Access Memory) is volatile and loses data when the power is turned off.

CD-RWs are used to create a backup of data and can be rewritten multiple times.

Magnetic tape is commonly used for long-term data backup and archival purposes.

The L1 cache in a CPU is used to execute program instructions quickly.

A memory module is used to expand the computer's memory capacity.

Magnetic tape is known for its high data storage capacity and is used for system backups.

The RAID 0 configuration is used to improve data performance by striping data across multiple disks.

SSDs have no moving parts, which contributes to their durability and fast data access times.

The memory management unit (MMU) in the CPU is responsible for managing memory storage.

The BIOS initializes hardware components and starts the boot process in a computer.

Optical drives use laser technology to read and write data to optical discs.

The memory bus transports data between the CPU and memory.

The instruction cache (I-cache) in the CPU is used to execute program instructions quickly.

Solid-State Drives (SSDs) are known for their high data access times and low power consumption.

DVD-Rs are used to create a backup of data and can be recorded once.
