Which of the following are considered main memory?
The main memory in a computer is called Random Access Memory. It is also known as RAM. This is the part of the computer that stores operating system software, software applications and other information for the central processing unit (CPU) to have fast and direct access when needed to perform tasks.
Which memory is difficult to T interface with processor?
To prevent them, DRAM refreshes periodically so due to refreshment it is difficult to interface with CPU. Since dynamic memory refreshes periodically so due to refreshment it is difficult to interface it.
Which of the following is the slowest in the memory hierarchy Mcq?
secondary memory
Explanation: The secondary memory is the slowest memory device. In the memory hierarchy, as the speed of operation increases the memory size also increases.
Which of the following is not considered as secondary memory?
Ram is random access memory which is used as processing the program bt it cannot be used as secondary storage as it cannot store any file.
Which of the following is not a type of secondary memory *?
Answer. RAM( random access memory) is not a secondary storage unit.
Which of the following is lowest memory hierarchy?
Answer: Memory Hierarchy: Auxiliary Memory. Auxiliary memory is known as the lowest-cost, highest-capacity and slowest-access storage in a computer system.
Which is the lowest memory hierarchy?
hard drive
Most modern computer systems use a hard drive made of magnetic or solid-state storage as the lowest level in the memory hierarchy (see Figure 8.4). Compared with the ideal large, fast, cheap memory, a hard drive is large and cheap but terribly slow.
Which one of the following is a slowest one in memory hierarchy?
Memory Hierarchy
| Speed | Memory |
|---|---|
| Fastest | Cache |
| RAM | |
| Slowest | Disk |
What are the auxiliary memory?
Auxiliary memory holds programs and data for future use, and, because it is nonvolatile (like ROM), it is used to store inactive programs and to archive data. … Since the 1980s, the most common forms of auxiliary storage have been magnetic disks, magnetic tapes, and optical discs.
What is secondary memory?
Secondary memory is also termed as external memory and refers to the various storage media on which a computer can store data and programs. The Secondary storage media can be fixed or removable.
Which is in the top of the memory hierarchy Mcq?
Memory Hierarchy MCQ Question 2 Detailed Solution
The correct answer is RAM. RAM is the fastest to read from and write to than the other kinds of storage in a computer.
What is not a primary memory?
It has a small capacity and we cannot store large amount of data in primary memory. Secondary memory is slower than primary memory but it is very cheap in terms of cost. It can be directly connected to the processor. So in the above question a) DVD is not a primary memory.
What are the 3 types of storage?
There are three main categories of storage devices: optical, magnetic and semiconductor. The earliest of these was the magnetic device. Computer systems began with magnetic storage in the form of tapes (yes, just like a cassette or video tape). These graduated to the hard disk drive and then to a floppy disk.
What are the 3 main types of secondary storage?
There are three main types of secondary storage in a computer system:
- solid state storage devices, such as USB memory sticks.
- optical storage devices, such as CD, DVD and Blu-ray discs.
- magnetic storage devices, such as hard disk drives.
What is the example of secondary memory?
Secondary memory is known as a Backup memory or Additional memory or Auxiliary memory. Hard Drive, SSD, Flash, Optical Drive,USD Drive are some examples of secondary memories in computer.
Is prom a secondary memory?
PROM is also nonvolatile memory.

What is non volatile memory?
Non-volatile memory (NVM) is a type of computer memory that has the capability to hold saved data even if the power is turned off. Unlike volatile memory, NVM does not require its memory data to be periodically refreshed. It is commonly used for secondary storage or long-term consistent storage.
What is a primary and secondary memory?
Computer memory is categorized into primary and secondary memory. While primary memory is the main memory of the computer which is used to store data or information temporarily, whereas secondary memory refers to external storage devices that are used to store data or information permanently.
Is Ram a secondary memory?
Computer memory is of two basic type – Primary memory(RAM and ROM) and Secondary memory(hard drive,CD,etc.). Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory. It is also called as read write memory or the main memory or the primary memory.
