Data Storage in Information Technology

What is the purpose of storage systems in computers?

• To manage and access digital data

• To process data and programs

• To connect to the internet

• To display images and videos

Which type of storage provides permanent or non-volatile storage?

• Random access memory (RAM)

• Secondary storage

• Cache memory

• Primary storage

What is the difference between random access and sequential access?

• Random access allows data retrieval in any order, while sequential access retrieves data in a specific order

• Random access retrieves data in a specific order, while sequential access allows data retrieval in any order

• Random access and sequential access are the same

• Random access and sequential access are not used in storage systems

Which storage technology uses magnetizing particles on a disk or tape to store data?

• Solid-state storage

• Optical storage

• Magnetic storage

What is the purpose of disk caching?

• To organize data efficiently

• To improve system performance by acting as a temporary high-speed holding area

• To compress files and reduce storage space

• To distribute write and erase cycles evenly across memory cells

Which type of optical disc can be written on once but cannot be erased or rewritten?

• Read-only (ROM) disc

• Write-once (R) disc

• Rewritable (RW) disc

• Double-sided disc

What is the main advantage of solid-state drives (SSDs) over hard disk drives (HDDs)?

• SSDs have no moving parts and are more durable

• HDDs have higher storage capacity

• SSDs are cheaper than HDDs

• HDDs have faster access times

What is the purpose of partitioning a hard drive?

• To organize data efficiently

• To improve system performance

• To increase storage capacity

• To connect multiple hard drives together

Which storage technology uses flash memory chips to store data?

• Magnetic storage

• Optical storage

• Solid-state storage

• Cloud storage

What is the purpose of wear leveling in solid-state drives (SSDs)?

• To extend the lifespan of the SSD

• To improve data integrity

• To increase the performance of the SSD

• To reduce the access time of the SSD
