What are the two main types of storage?
There are two types of storage devices used with computers: a primary storage device, such as RAM, and a secondary storage device, such as a hard drive. Secondary storage can be removable, internal, or external. Why is storage needed in a computer?
What type of storage is ROM?
Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device.
Is ROM primary storage?
The two main types of primary storage are ROM, which is non-volatile , and RAM, which is volatile . Non-volatile memory keeps its contents even when the computer is switched off.
Is hard disk primary or secondary storage?
A computer’s internal hard drive is often considered a primary storage device, while external hard drives and other external media are considered secondary storage devices. However, primary and secondary storage may also refer specifically to the components inside the computer.
What are the three 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.
Is SSD primary or secondary storage?
This type of storage technology is known as secondary storage, while a computer’s RAM (Random Access Memory) is known as its primary storage. An SSD is a type of secondary storage, so it’s used for storing personal data, like pictures, videos, music, and documents.
What is the most commonly used secondary storage device?
Answer: The most commonly used secondary storage devices are pendrives , CD’s, ( compact disk) Flash drive, DVDs , sd card, etc.
What is another name for secondary storage?
Also called auxiliary storage, auxiliary memory, external storage, secondary memory .
What are the characteristics of secondary storage media?
Secondary storage devices are non-volatile and are typically high capacity, portable or both….Storage devices
- speed (how quickly data can be accessed)
- cost per storage unit (i.e. price per gigabyte or megabyte)
- durability (toughness)
- portability (how easy it is to move it from one computer to another)
Which of the following is secondary memory?
Secondary memory is where programs and data are kept on a long-term basis. Common secondary storage devices are the hard disk and optical disks. The hard disk has enormous storage capacity compared to main memory. The hard disk is usually contained inside the case of a computer.
What is secondary memory give example?
Secondary memory refers to storage devices, such as hard drives and solid state drives. It may also refer to removable storage media, such as USB flash drives, CDs, and DVDs. Unlike primary memory, secondary memory is not accessed directly by the CPU.
Which of the following is a secondary memory device exam Veda?
Solution(By Examveda Team) Floppy Disk : A floppy disk, also known as a floppy, diskette, or simply disk, is a type of disk storage composed of a disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic enclosure lined with fabric that removes dust particles.
Which of the following is the secondary device?
Answer. Answer: secondary storage device is floppy disk, magnetic tape and flash memory …
Which of the following is not a secondary storage?
RAM( random access memory) is not a secondary storage unit. Secondary storage is non-volatile memory that is not directly accessible by CPU, because it is not accessed via input/output channels.
Which of the following is used as primary storage device?
Random Access Memory (RAM) and cache are both examples of a primary storage device. The image shows three different types of storage for computer data. Primary storage’s key differences from the others are that it is directly accessible by the CPU, it is volatile, and it is non-removable.
Is magnetic drum a primary storage device?
A magnetic drum, also referred to as drum, is a metal cylinder coated with magnetic iron-oxide material on which data and programs can be stored. Magnetic drums were once used as a primary storage device but have since been implemented as auxiliary storage devices.
Is floppy disk a primary storage device?
For more than two decades, the floppy disk was the primary external writable storage device used. Most computing environments before the 1990s were non-networked, and floppy disks were the primary means to transfer data between computers, a method known informally as sneakernet.
Which of the following is primary memory?
Primary memory is computer memory that is accessed directly by the CPU. This includes several types of memory, such as the processor cache and system ROM. However, in most cases, primary memory refers to system RAM.
What is an example of primary storage?
RAM (random access memory) and cache are both examples of a primary storage device. A primary storage device may also be referred to as internal memory, main memory, main storage, and primary memory.
What is primary memory give example?

What is other name of primary memory?
Types of Computer Memory: Primary and Secondary Although many types of memory in a computer exist, the most basic distinction is between primary memory, often called system memory, and secondary memory, which is more commonly called storage. The key difference between primary and secondary memory is speed of access.
