What is the function of the memory in the computer?

1. Core memory:

It is the main form of random access computer memory. This type of memory is often referred to as core memory, or informally as core memory.

The core uses tiny magnetic rings (rings) that thread to write and read information. Each core represents a bit of information. The core can be done in two different ways (clockwise.

or counterclockwise).

The bits stored in the core are zero or one, depending on the direction of magnetization of the core.

The wiring is laid out in such a way that the individual cores are set to either 1 or 0 and their magnetization is altered by sending an appropriate current pulse to the selected wire. The process of reading the kernel causes the kernel to reset to zero, which erases it. This is called a destructive reading.

When no read or write operations are performed, the kernel retains the last value even if the power is turned off. This makes them non-volatile.

2. Semi-conductor memory

It is a kind of memory and internal memory that uses semiconductor circuits as storage.

It is a semiconductor integrated circuit called a memory chip.

Compose. According to its function, it can be divided into: random access memory.

abbreviated as RAM) and read-only memory.

Read-only ROM). Small size, fast storage speed, high storage density, and logic circuits.

The internal memory of a computer can be divided into ROM according to functionram .cache。

ROM is an abbreviation for Read-Only Memory, which is a type of solid-state semiconductor memory that can only read out previously stored data. It is characterized by the fact that once the information is stored, it cannot be changed or deleted. It is usually used in electronic or computer systems that do not require frequent data changes, and the data does not disappear due to power off.

RAM, also known as main memory, is the internal memory that exchanges data directly with the CPU. It can be read and written at any time (except when refreshed), and it is fast, often as a temporary data storage medium for the operating system or other running programs. When RAM is working, information can be written (deposited) or read (withdrawn) from any specified address at any time.

The biggest difference between it and ROM is the volatility of the data, that is, the data stored in the event of a power failure will be lost. RAM is used in computers and digital systems to temporarily store programs, data, and intermediate results.

Cache uniquely provides three consolidated database technologies that can access the same data concurrently: mature object access, high-performance SQL access, and rich multi-dimensional access. There is no need for mappings between object, relational, and multidimensional data views, which greatly reduces development and run time.

The computer's memory is made up of random access.

Read-only memory, as well as cache.

Three-part composition. Memory is one of the most important components of a computer and is a bridge to communicate with the CPU. The running of all programs in the computer takes place in memory, so the performance of the memory has a very large impact on the computer. Memory is also known as internal memory.

It is used to temporarily store computing data in the CPU and to exchange data with external memory such as hard disks. <

A computer's memory is composed of random access memory (RAM), read-only memory (ROM), and cache.

Memory is one of the most important components of a computer, and it is the bridge that communicates with the CPU. The running of all programs in the computer takes place in memory, so the performance of the memory has a very large impact on the computer. Memory, also known as internal memory, is used to temporarily store computing data in the CPU and to exchange data with external memory such as hard disks.

As long as the computer is running, the CPU will transfer the data that needs to be calculated to the memory for calculation, and when the operation is completed, the CPU will send the result out, and the operation of the memory also determines the stable operation of the computer. Memory is made up of memory chips.

Circuit boards, gold fingers.

and other parts.

A computer's internal memory includes registers, cache memory, and main memory.

As soon as the computer is running, the operating system will transfer the data that needs to be computed from the memory to the CPU for processing. When the computation is complete, the CPU sends the result out.

The operation of memory also determines how fast or slow the computer as a whole runs. A memory module consists of a memory chip, a circuit board, a gold finger, and other parts.

A computer's memory includes both internal and external memory.

Internal memory is referred to as memory, which generally refers to the memory module inserted into the computer motherboard, but also includes the memory on the motherboard, CPU, graphics card, sound card, etc., the memory on these cards is generally faster and is the best memory.

Memory includes RAM and ROM, ROM is generally very small, mainly used to store BIOS and some information (for example, there are some ROMs on the memory module in addition to RAM to store RAM information), but the size of ROM is generally very small and often ignored, so sometimes we talk about memory also refers to RAM, that is, memory.

External memory such as hard disk, floppy disk, zip disk, U disk, magnetic tape, etc., the corresponding drive is also called external memory, and some memory and storage medium are made together, such as hard disk, U disk, etc.

A computer's memory is divided into internal memory and external memory.

A computer's memory can be divided into internal memory and external memory. Internal memory is frequently used by computers during program execution and is directly accessible during an instruction cycle. External memory requires a computer to read information from an external storage device, such as a tape or disk.

The main function of memory is to store programs and data. The program is the basis for the operation of the computer, and the data is the object of the operation of the computer. In order to realize automatic calculation, all kinds of information must be stored somewhere in the computer in advance, and this place is the memory.

The main functions of the memory:

The main function of memory is to read and write, for random access memory, flash memory, first-in-first-out memory and first-in-last-out memory, the main function is to read and write, and for read-only memory, the main function is only read, not written. The memory can be a card or a floppy disk, which can be active or fixed, and can be used to save images.

Memory is categorized by storage medium:

1. Semiconductor memory.

The memory element is composed of semiconductor devices, and the memory of Xunhuai is called semiconductor memory. It has the advantage of small size, low power consumption, and short access time.

2. MOS semiconductor memory.

It has the characteristics of high integration, and is simple to manufacture, low cost, and low power consumption, so the bipolar (dingl) semiconductor memory: has the characteristics of high speed.

3. Magnetic surface memory.

Magnetic surface memory is to coat a layer of magnetic material on the surface of the metal or plastic matrix as a recording medium, and the magnetic layer runs at high speed with the carrier magnet during work, and the magnetic head is used to read and write on the magnetic layer, so it is called magnetic surface memory. Features: Memory is non-volatile.

4. Optical disc memory.

Optical disc memory is a memory that is read and written on the recording medium (magneto-optical material) by applying laser, which is characterized by high disc recording density, good durability, high reliability and strong interchangeability.

1. Internal memory.

It is where the combinator reads and stores the data, and cooperates with the combinator to complete the calculation and control.

Also known as the main memory.

It is divided into random read-write memory (RAM) and read-only memory (ROM).

2. External memory.

External memory is used to store a large amount of data, programs, and can still be saved after power failure.

Common ones are: floppy disks, hard disks, optical discs, USB flash drives, and tape drives.
