What is Memory explain its types?

Memory is the process of taking information from the world around us, acting on it, storing it and later remembering that information, sometimes many years later. Human memory is often compared to a computer memory system or filing cabinet.
                                                                     OR
Memory is just like the human brain. It is used to store data and instructions. Computer memory.
The storage space in the computer where the data is to be processed and the instructions are required.
Processing is stored. Memory is divided into a large number of small parts called cells. each one
Location or cell has a unique address that varies from zero to memory size minus one. of the
For example, if a computer has 64k words, then this memory unit has 64 * 1024 = 65536 memory.
Locations The address of these locations varies from 0 to 65535.
There are basically three types of memory.
  • Cache memory
  • Primary memory / Main memory
  • Secondary memory

What is Cache memory?

Cache memory is a very fast semiconductor memory that can speed up the CPU. It works as one.
Buffer between CPU and main memory. It is used to store data and these parts of the program.
Which are often used by the CPU. Data and program parts are transferred from disk.
To cache memory through the operating system, from where the CPU can access them.

What is primary memory?

Primary storage (also called main memory) is a component of a computer that contains the data, programs, and instructions currently in use. Basic storage is located on the motherboard. As a result, data can be read and written much faster than primary storage.
Example of main memory

 Example of primary memory are  RAM - Random Access Memory. ROM - Read Only Memory.

What is Secondary memory?

Secondary memory is also called external memory and refers to the various storage media on which a computer can store data and programs. Secondary storage media can be fixed or removable. Fixed storage media is an internal storage medium similar to a hard disk that is fixed inside a computer.
Secondary memory consists of all permanent or persistent storage devices, such as read-only memory (ROM), flash drives, hard disk drives (HDD), magnetic tapes and other types of internal/external storage media.

Language translators

 What is language translator? Any program written in high level language is known as source code. However, computers cannot understand the source code. Before running it, the source code must first be translated into a form that the computer understands. Translator is a program that converts source code into machine code. There are generally three types of translators:  compilers Interpretor Assembler What is compilers? The compiler takes the source code as a whole and translates it into machine code at once. Once converted, the object code can be run at any time without assistance. This process is called compilation. Compilers have several advantages: Compiled programs run faster, because they have been translated. A compiled program can be provided as an executable file. An executable file is a file that is ready to be executed. Because an executable file cannot be easily edited, programmers prefer to provide an executable rather than a source code.Developers improve the cod...

What is RAM and ROM?

   What is RAM? RAM stands for Random Access Memory. Practically all computers now Or they rely on memory to perform all their functions. It becomes without RAM. It is impossible to go far after the PC is turned on. Software Applications installed on a computer are largely dependent on RAM. it is Responsible for keeping data while any application is running. Once The application is closed without saving, data is lost.RAM is short for "Random Access Memory" and although it may seem mysterious, RAM is one of the most basic elements of computing. RAM is the fastest and temporary data storage space that a computer needs to access right now or in the next few moments. The difference between Ram and Sam RAM is considered "random access" because it can access any memory cell. This is done directly if the intersection of rows and columns is well known. On the contrary RAM is Serial Access Memory (SAM). SAM stores data as a series of memory cells. Which can only be accessed ...

what is printer and its types?

 What is printer? "A printer is an external output device that takes data from a computer and generates output in the form of graphics / text on a paper".   There are two types of printers.  Impact printer Non-impect printer  What is Impect printer? An impact printer makes contact with the paper. It usually forms the print image by pressing an inked ribbon against the paper using a hammer or pins. Following are some examples of impect printer.  Dot-Matrix Printers: The dot-matrix printer uses print heads containing from 9 to 24 pins. These pins produce The dot-matrix printer uses print heads containing from 9 to 24 pins. These pins produce produces more dots that a 9 pin dot-matrix printer, which results in much better quality and clearer characters. The general rule is: the more pins, the clearer the letters on the paper. The pins strike the ribbon individually as the print mechanism moves across the entire print line in both directions, i-e, from lef...
