The word Memory is derived from the Latin word Memoria, meaning Remembrance. Memory is the faculty of the mind by which information is remembered.
In computer, Memory is a storage area where data and programs are kept while they are not being used. There are three types of Memory in computer:
1. Random Access Memory (RAM)
RAM is a type of Memory that can be accessed randomly; that is, any byte of information in RAM can be accessed without having to read through the preceding bytes. RAM is volatile, meaning that its contents are lost when power is turned off.
2. Read-Only Memory (ROM)
ROM is a type of Memory that can only be read, not written to. ROM is non-volatile, meaning that its contents are not lost when power is turned off.
3. Secondary Storage
Secondary Storage is a type of Memory that is not random access and can only be accessed sequentially. Secondary Storage is non-volatile, meaning that its contents are not lost when power is turned off.

What is memory in a computer?
Computer memory is an electronic device that stores digital information. It is a fundamental component of all computers. Memory is used to store data and programs currently being used by the computer. It is also used to store temporary data that is being processed by the computer.
There are three main types of computer memory: random-access memory (RAM), read-only memory (ROM), and hard disk drive (HDD).
RAM is the main type of memory used by computers. It is a type of volatile memory, which means that the data is lost when the power is turned off. RAM is used to store the operating system, programs, and data that is currently being used by the computer. The more RAM a computer has, the more programs it can run simultaneously.
ROM is a type of nonvolatile memory. It is used to store the basic instructions that allow a computer to start up. ROM is also used to store data that is not currently being used by the computer, such as the BIOS and device drivers.
HDD is a type of permanent storage. It is used to store data that is not currently being used by the computer, such as photos, music, and videos. HDD is also used to store the operating system and programs.
What is computer memory and its types?
Computer memory, also known as RAM (random access memory), is a component of every computer. It stores the data and instructions that the computer is currently working with.
There are three main types of computer memory:
1. Static random access memory (SRAM): This is a fast type of memory that is used for the CPU cache and other high-performance tasks.
2. Dynamic random access memory (DRAM): This is the most common type of memory, and is used for most tasks.
3. Flash memory: This is a type of non-volatile memory that is used for storage devices such as USB drives and memory cards.
Static random access memory is a type of memory that is used for the CPU cache and other high-performance tasks. It is fast and expensive, so it is not used for general-purpose tasks.
Dynamic random access memory is the most common type of memory, and is used for most tasks. It is slower than SRAM, but cheaper.
Flash memory is a type of non-volatile memory that is used for storage devices such as USB drives and memory cards. It is slower than DRAM, but cheaper and has a longer lifespan.
What is computer memory with example?
Computer memory is a fundamental component of a computer system. It is used to store data and programs that are being used by the computer. There are a variety of different types of computer memory, but the most common are RAM and ROM.
RAM is short for random access memory. It is a type of memory that can be accessed randomly. This means that you can access any memory location without having to go through the other locations first. RAM is volatile, which means that it loses its data when the power is turned off.
ROM is short for read only memory. It is a type of memory that can only be read from, not written to. ROM is non-volatile, which means that it retains its data even when the power is turned off.
Both RAM and ROM are important for a computer system. RAM is used to store the data and programs that are being used by the computer at any given time. ROM is used to store the basic instructions that are needed to start up the computer.
Where is memory in computer?
In computing, computer memory refers to the storage locations within a computer where data is kept so that it can be accessed by the processor. The phrase “computer memory” is often used to mean the primary storage of a computer, which is generally composed of dynamic random access memory (DRAM) chips. In older computers, primary storage was often composed of magnetic disk drives.
Primary storage is where data is stored when it is first loaded into memory from a storage device, such as a hard drive. The processor can access data from primary storage much more quickly than it can from other storage devices.
Most of the data in primary storage is kept in the form of bits, with each bit corresponding to a single letter, number, or symbol. The amount of data that can be stored in a bit is called a byte. There are 8 bits in a byte.
When a computer is turned off, the data in primary storage is lost. This is because the power is turned off and there is no way to keep the data in memory without a power supply.
In order to keep data in memory when the computer is turned off, it needs to be saved to a secondary storage device, such as a hard drive. When the computer is turned on, the data can be reloaded from the secondary storage device into primary storage.
Some of the data in primary storage is also kept in the form of pages. A page is a unit of memory that is usually 4,096 bytes long. The amount of data that can be stored in a page depends on the type of data and the type of computer.
Pages are used to store data that is going to be accessed frequently by the processor. The processor can access data from a page much more quickly than it can from bits or bytes.
Pages are also used to store data that is going to be changed frequently. When data is changed, the changes are usually made to the page that contains the data. This helps to ensure that the changes are made as quickly as possible.
The amount of data that can be stored in a computer’s memory depends on the type of computer and the type of memory that is used. The table below shows the approximate maximum amount of data that can be stored in various types of computer memory.
Computer Memory
Maximum Data Capacity
Dynamic random access memory (DRAM)
64 gigabytes
Static random access memory (SRAM)
256 megabytes
Volatile random access memory (VRAM)
128 megabytes
Non-volatile random access memory (NVRAM)

What is memory word?
In computing, a memory word is the fundamental unit of information in a computer’s memory. The size of a memory word is typically 8, 16, 32, or 64 bits.
What is memory device?
A memory device is any physical object that can store digital information. The most common type of memory device is a computer hard drive, but other examples include USB flash drives, memory cards, and external hard drives.
When you save a file on your computer, it’s stored on the hard drive. The hard drive is a type of memory device that uses spinning disks to store data. The faster the disks spin, the faster the computer can access the data.
Other types of memory devices include optical discs, such as CDs and DVDs, and magnetic tapes. Optical discs store data as a series of microscopic bumps on the surface of the disc. Magnetic tapes store data as a series of magnetic particles on a strip of tape.
Most memory devices are portable, meaning you can take them with you wherever you go. This makes them perfect for storing photos, music, and videos.
If you need more storage space than your memory device can provide, you can use an external hard drive. External hard drives are larger than standard memory devices, and they can store more data. They can also be used to back up your computer’s hard drive.
If you’re looking for a memory device that’s easy to use and doesn’t require a computer, consider a USB flash drive. USB flash drives are small, lightweight, and portable. They can also be used to run portable applications and to store files.
Whether you’re looking for extra storage space or a way to take your files with you, there’s a memory device that’s perfect for you.
What are the functions of memory?
Memory is a process that allows an individual to store and recall information. There are several different functions of memory that allow this process to work effectively.
One function of memory is to store information. This can be done through sensory input, such as seeing, hearing, or touching something. The information is then processed by the brain and is stored in the individual’s memory. The information can be recalled later when needed.
Another function of memory is to help individuals learn. When individuals are learning something new, their memory is working to help them retain that information. The memory helps to store the information and also to create associations between different bits of information. This helps the individual to learn and recall information more easily.
A third function of memory is to help individuals remember past events. This function allows individuals to recall details of events that have occurred in the past. This can be helpful in recalling information for tasks such as test taking or in everyday life situations.
Finally, the memory can also be used to plan for the future. This function allows individuals to remember things that they need to do in the future. This can help them to stay organized and to be successful in completing tasks.
All of these functions of memory work together to help individuals learn, remember, and interact with the world around them.
