What are the three subsystems of a computer system?

What are the three subsystems of a computer system?

We can divide the parts that make up a computer into three broad categories or subsystem: the central processing unit (CPU), the main memory and the input/output subsystem.

What are the 3 types of computer memory explain with examples?

Computer memory is of two basic types – 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.

What are types of memory in computer?

14 types of computer memory

• Internal. Internal memory, also known as primary memory, stores small amounts of data that the computer can access while you’re actively using it.
• RAM. Random access memory (RAM) is the primary internal memory of the central processing unit (CPU).
• DRAM.
• SRAM.
• ROM.
• PROM.
• EPROM.
• EEPROM.

What are four types of memory that are used in computers systems?

Computer memory is a generic term for all of the different types of data storage technology that a computer may use, including RAM, ROM, and flash memory. Some types of computer memory are designed to be very fast, meaning that the central processing unit (CPU) can access data stored there very quickly.

What is the function of the memory subsystem in a computer?

All memory subsystem components are for automatically retrieving operands from and storing results in their associated memory modules. All memory subsystem components have an output data connection and an input data connection.

What is a CPU subsystem?

The processor subsystem consists of one or more processors that operate together to execute application and system programs. The central processor performs logical processing for all programs executed on the system.

Which are the 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 floppy disks. The hard disk is used for long-term storage of programs and data.

What are the two basic types of RAM?

There are two main types of RAM: Dynamic RAM (DRAM) and Static RAM (SRAM).

• DRAM (pronounced DEE-RAM), is widely used as a computer’s main memory.
• SRAM (pronounced ES-RAM) is made up of four to six transistors.

What is the main memory of computer?

Main memory is the primary, internal workspace in the computer, commonly known as RAM (random access memory). Specifications such as 4GB, 8GB, 12GB and 16GB almost always refer to the capacity of RAM. In contrast, disk or solid state storage capacities in a computer are typically 128GB or 256GB and higher.

Is cache a memory?

The cache is a smaller and faster memory which stores copies of the data from frequently used main memory locations. There are various different independent caches in a CPU, which store instructions and data. It is a type of memory in which data is stored and accepted that are immediately stored in CPU.

What is difference between RAM and ROM?

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. Find out more about RAM.

What is a computer subsystem?

A unit or device that is part of a larger system. For example, a disk subsystem is a part of a computer system. A subsystem usually refers to hardware, but it may be used to describe software. However, “module,” “subroutine” and “component” are more typically used to describe parts of software.
