A computer system consists of hardware and software components that work together to perform tasks. The hardware components of a computer system include the central processing unit (CPU), memory, storage devices, and input/output (I/O) devices. The software components include the operating system and application programs.
The CPU, also known as the processor, is the brain of the computer. It executes instructions and performs calculations for the computer. The memory, or main memory, stores data and instructions for the CPU to access and use. There are two types of memory: random access memory (RAM) and read-only memory (ROM). RAM is volatile memory, which means it is erased when the computer is turned off. ROM is non-volatile memory, which means it retains its data even when the power is off.
Storage devices, such as hard drives and solid-state drives, are used to store data and programs permanently. Input devices, such as a keyboard and mouse, allow a user to input data into the computer. Output devices, such as a monitor and printer, allow the computer to display or print the results of its processing.
The operating system is the software that controls the hardware and coordinates the execution of application programs. It provides a user interface, manages the resources of the computer, and performs tasks such as scheduling, input/output operations, and memory management. Application programs are software designed to perform specific tasks, such as word processing, web browsing, or playing games.
In summary, a computer system is made up of hardware and software components that work together to process data and perform tasks. The CPU and memory handle the processing, storage devices store data, and I/O devices allow for interaction with the user. The operating system coordinates the operation of these components and runs application programs.
5 Basic Structure of Computer System
There are four steps that nearly all CPUs use in their operation: fetch, decode, execute, and write back. Scanners allow information such as a photo or text to be input into a computer. These devices display information that has been held or generated within a computer. And lastly, in the fourth section is the computer's storage device s , which contains permanent information such as documents and pictures. The remaining parts of the number usually provide information required for that instruction, such as operands for an addition operation. Drive Motor: A very small spindle motor engages the metal hub at the center of the diskette, spinning it at either 300 or 360 rotations per minute RPM. When the disk is inserted into the disk drive, the drive hooks into those holes to spin the circle.
Computer System Organisation
This kind of memory is located on one or more microchips that are physically close to the microprocessor in your computer. This can be accomplished through the monitor or other graphical display , printer, speakers etc. It is used for permanent storage of data. Track ball looks like a mouse, as the roller is on the top with selection buttons on the side. There are various structure of computer, which are given below. Output units are also known as video cards, graphics cards, display adapters, and monitors. Otherwise, the instruction is an input-output type having bit 1 at position 15.
What are the four basic functions of a computer system?
The central processing acts as the boss in complete computer architecture. If storage was removed, the device we had would be a simple calculator instead of a computer. OUTPUT DEVICES : Output devices display information in a way that you can you can understand. At a fundamental level, computers operate through these four functions: input, output, processing, and storage. The data on the CD is recorded as a series of microscopic pits and lands physically embossed on an aluminum substrate. On the disks, there are many tracks or cylinders. It is sometimes considered better than a mouse, because it requires little arm movement and less desktop space.
