FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Hard drive is used for permanent storage or long term storage of data. The capacity of RAM is 256 MB to 32 GB. The capacity of hard disk is 500 GB to 8 TB. Thus, hard disk can store more data in comparison to RAM and hence has more capacity.

Detailed explanation-2: -When it comes to memory capacity, the hard disk starts where RAM stops; this means that hard disk size is always bigger than RAM. Currently, RAM size ranges from 256MB to 32GB. The size of the hard drive that is accessible spans from 500GB to 8TB.

Detailed explanation-3: -Computers need some form of non-volatile storage-a place where data can stay even when the computer is turned off, so you don’t have to reload and re-enter everything each time you use the computer. That’s the point of having storage in addition to RAM.

Detailed explanation-4: -As of 2020 SSDs started to compete with HDDs. As of May 2022, the largest hard drive is 26 TB (while SSDs can be much bigger at 100 TB, mainstream consumer SSDs cap at 8 TB). Smaller, 2.5-inch drives, are available at up to 2TB for laptops, and 5TB as external drives.

Detailed explanation-5: -RAM data is volatile and is erased once the computer is switched off. HDD, hard disk, has permanent storage and it is used to store userspecific data and operating system files. HDD data is static and remains in the computer even if computer is switched off.
