What are the primary storage devices?

There are four types of primary storage:read only memory (ROM)random access memory (RAM)flash memory.cache memory..

What is secondary storage device?

Secondary storage is non-volatile , long-term 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 are the 2 types of primary memory?

There are two key types of primary memory:RAM, or random access memory.ROM, or read-only memory.

Which one of the following is a secondary storage device?

Typical secondary storage devices include magnetic tape drives, magnetic disk drives, compact optical disk drives, and archival storage devices such as disk jukeboxes.

What is primary memory and its type?

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. … Therefore, each time you start up your computer, the operating system must be loaded from secondary memory (such as a hard drive) into the primary memory, or RAM.

Is ROM primary or secondary storage?

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.

What is the difference between primary and secondary industry?

Primary: involves the retrieval and production of raw materials, such as corn, coal, wood and iron. … Secondary: involves the transformation of raw or intermediate materials into goods e.g. manufacturing steel into cars, or textiles into clothing. (A builder and a dressmaker would be workers in the secondary sector.)

What is primary and secondary memory with example?

Primary memory is the main memory of the computer system. Accessing data from primary memory is faster because it is an internal memory of the computer. All secondary storage devices which are capable of storing high volume data is referred to as secondary memory. Types of Primary Memory 1) RAM, 2) ROM.

What are the types of secondary memory?

Depending on whether secondary memory device is part of CPU or not, there are two types of secondary memory – fixed and removable. Let us look at some of the secondary memory devices available.

What is primary storage device and examples?

A primary storage device is a medium that holds memory for short periods of time while a computer is running. … RAM (random access memory) and cache are both examples of a primary storage device. The image shows three different types of storage for computer data.

What is difference between primary and secondary memory?

Primary memory is directly accessible by Processor/CPU. Secondary memory is not directly accessible by the CPU. … The memory devices used for primary memory are semiconductor memories. The secondary memory devices are magnetic and optical memories.

What are the characteristics of secondary storage media?

Answer:Answer:i) High Capacity: Secondary storage devices like external hard drive can have high memory capacity than the primary memory.ii) Portable: Since secondary storage devices are external devices they are portable and can be connected to different computer systems.iii) Durable: highly durable in nature.More items…•

What is the difference between primary and secondary activities?

(i) Primary activities include activities, such as hunting, fishing, mining, agriculture. (i) Secondary activities include manufacturing and constructions. (ii)These activities concerned with are obtaining materials directly from nature. For example, fish from water or wood from trees.

What is secondary memory 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. … For example, a computer may have a one terabyte hard drive, but only 16 gigabytes of RAM.
