What is external memory of computer?

External memory, also called “secondary memory” refers to a storage device that can retain or store data persistently. They could be embedded or removable storage devices. Examples include hard disk or solid state drives, USB flash drives, and compact discs.

What is called external memory?

When computers need to store data for long-term retrieval, they use secondary memory, also known as auxiliary storage or external memory.

What is external memory with example?

Another popular type of external memory is the flash drive, which is a small device that can store and transfer data to and from various other devices. It has plenty of other names such as USB drive, pen drive, thumb drive, and more.

What is Class 4 external memory?

Secondary storage (or external memory) differs from primary storage because they are not directly accessible by the CPU. The computer usually uses its input/ output channels to access secondary storage and then transfers the desired data using an Intermediate area in primary storage. Fill in the blanks: 1.

What are the example of external storage device?

Some of the examples of external storage devices are- Pen drives, CDs, and DVDs. A pen drive is a small self-powered drive that connects to a computer directly through a USB port.

What is the use of external memory?

External storage enables users to store data separately from a computer’s main or primary storage and memory at a relatively low cost. It increases storage capacity without having to open up a system.

Where is external memory?

Typically refers to storage in an external hard drive or on the Internet. The main “memory” in the computer is the computer’s workspace, not its storage facility. See external storage.

Why is external memory important?

What is the example of external storage?

What are the external devices?

Any peripheral device that is not housed inside the computer cabinet. Monitors, keyboards, mice and printers are inherently external devices; however, drives, network adapters and modems may also be external.

What is data in computer for Class 4?

SYNOPSIS: • The words or numbers which have no meaning by themselves is called data. It is the. input given to the computer.

What is a computer answer for Class 4?

Answer: A computer is an electronic device created by the Charles Babbage. Computers can process huge amounts of data very quickly and display accurate results. A computer is made up of three main parts: The Input Unit, The Processing Unit and The Output Unit.

What do you call external memory on a laptop?

External media is also known as auxiliary memory or secondary storage. Hard drives sold with laptops are usually of a comparably low capacity when compared to their desktop counterparts due to size. This means that many people turn to alternative long-term storage devices that complement the internal memory.

How is external storage used in a computer?

External storage is often used as a form of a backup or for transportation of data from one system to another. External storage allows the user to store information, especially data that is not used frequently, outside the computer’s main memory without much additional cost, since the cost per bit…

What’s the difference between internal and external memory?

In computer systems today, there are two types of memory: Internal memory is normally associated with RAM (or random access memory) and is also known as main memory. It’s typically smaller in size but has faster access times. External memory, also known as secondary memory, is separate from main memory.

How does a Microprocessor access external memory?

Whenever the microprocessor accesses external memory, the chip enable signal CE ¯ is active (asserted low); it is thus connected to the CE ¯ pin of the flash memory device. To allow the microprocessor to fetch data from external memory, the corresponding output enable signals OE ¯ (active low) are connected.
