Question

5. Which of the following is lowest in memory
hierarchy?​

Answer 1

The full question is "Which of the following is lowest in the memory hierarchy? (A) Cache memory(C) Register (B) Secondary memory  (D) RAM "

The one which is the lowest in the memory hierarchy is Secondary memory (Option B).

• Memory hierarchy refers to how different types of storage on a computer are organized based on how quickly they may be accessed. CPU registers, which are the fastest to read and write to, are the highest performing storage at the very top. The levels are as follows, At level 0 there is CPU registers, then in Level 1 Cache, at level 2 there is Primary memory, then secondary memory, and then tertiary memory.
• The first option Cache memory is at 1st level, so it's not correct. The second one is Register, which is at a higher level. The RAM is itself in primary memory . The secondary memory is the lowest in the memory hierarchy. The Harddisks, USD, USB, Memory card,and SSD are the examples of secondary memory.

Answer 2

Answer:

Secondary memory

The hierarchy of memory places secondary memory is least.

Explanation:

Memory hierarchy is a component of computer system design that aids in organizing memory to cut down on access time. The architecture of the computer system made the use of a processor and an enormous number of memory devices.

Computer memory that is non-volatile, permanent, and not easily accessable by a computer or processors is referred to as secondary memory. Users can save information and files that can be instantly and readily accessed, communicated, and used by apps and other services.

The physical parts of a computer used to temporarily or permanently store programming or data are referred to as memory. It is a group of registrations.

This type of memory is known as secondary memory. Data and applications are kept in secondary memory.

There are numerous uses for secondary memory.

• We are all aware that primary memory simply keeps information whenever the power is on and destroys information when the power is off. As a result, we need a backup memory that can continue to save data even after the power is switched off.
• Secondary memory offers a substantial quantity of storage capacity, enabling us to constantly store massive amounts of data like movies, photos, music files, and other objects.
• The secondary devices could be uninstalled in some cases. Data may be stored and easily transferred from one gadget to a different as a result.
