How is data stored on a magnetic hard disk?
A magnetic disk drive consists of a number of platters (disks) coated in a magnetic material. They spin at around 7200 rpm . The data is encoded into bits and written onto the surface as a series of changes in the direction of the magnetisation. The data is read by detecting the changes in direction.

What is the meaning of storage devices?
A storage device is a piece of hardware that is primarily used for storing data. Every desktop computer, laptop, tablet, and smartphone will have some kind of storage device within it, and you can also get standalone, external storage drives that can be used across multiple devices.
What is permanent storage in computer?
Permanent storage, also called persistent storage, is any computer data storage device that retains its data when the device is unpowered. A common example of permanent storage is the computer’s hard drive or SSD. Examples of permanent storage devices.
What 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. RAM, or random access memory, consists of one or more memory modules that temporarily store data while a computer is running.
What is primary memory with example?
2. Secondary Memory / Mass Storage:
| Sr.No. | Primary memory |
|---|---|
| 5. | The memory devices used for primary memory are semiconductor memories. |
| 6. | Primary memory is also known as Main memory or Internal memory. |
| 7. | Examples: RAM, ROM, Cache memory, PROM, EPROM, Registers, etc. |
What is primary memory give example?
An example of Primary memory is RAM and ROM that store programs. These memories are limited in capacity and manufactured by using integrated circuits (IC) or semiconductor device. Its speed of Data accessing is faster than secondary memory.
What are the two types of primary memory?
There are two key types of primary memory:
- RAM, or random access memory.
- ROM, or read-only memory.
What are the main parts of memory?
The three main stages of memory are encoding, storage, and retrieval. Problems can occur at any of these stages. The three main forms of memory storage are sensory memory, short-term memory, and long-term memory.
Is ROM 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.
Is ROM a permanent memory?
RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
Why computers have both main memory and secondary storage?
Because the main memory can quickly let the program access data from any random location, but can easily be erased when the computer is turned off. Secondary storage can help keep some of the lost data and can create a backup for important files or programs regardless of the computer power.
Is an example of secondary memory?
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.
What are the two 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.
What are the two examples of secondary memory?
The hard disk, CD- ROM, DVD are examples of secondary memory devices.
What are the four types of secondary memory?
Secondary memory has four categories like as Magnetic Storage, Optical Storage, Flash storage, and Online Cloud System.
How many types of secondary memory are there in computer?
three
Which is the smallest unit of memory?
Computers work in binary digits, combining 0’s and 1’s in countless patterns. These binary digits are known as bits, and are the smallest possible unit for data storage. When 8 bits are combined, you get a byte.
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.
