  • System Software


Let's discuss the points above about the computer system and fundamentals of computers related to the topic of "What are the 4 basic parts of a computer?" explanation following below here:


There are four basic parts of the computer system explanation following below here:


Input and output system 

Input and output system is a unit of sending the instructions according to the types of unit system. Such as input devices are used to send the instructions to the computer system and output devices are used to send instructions to the user in the form of the output data when the user needs the output data.

Input unit and output unit is controlled by the control unit and operating system to allow it to connect with the computer system.

Similarly the operating system is also allowed to connect the output device to the computer system. Without the output device the user cannot understand the computer output data from the CPU and input device is also important to send the instructions to the computer to understand in the binary code.


Process system 

Process system is the most important part of the computer because it is the brain of the computer system which is used to process the instructions, data, program etc given by the order of the user.

Process system is used to solve the computing problem of the user such as the logical and calculative problem on the computer system provided through the output device of the computer system that is connected to the CPU. 

The CPU is also known as the brain of the computer system and the CPU is a chip of the computer that is implemented on the motherboard of the computer system. The CPU contains CU and ALU which is known as the control unit as CU and ALU as the arithmetic and logic unit of the central processing unit or CPU.


Memory and management

Memory and its management of the computer system is necessary because the data, instructions and program which is ready for execution on the CPU is stored into the memory which is known as primary memory of the computer system.

The primary memory is a type of the temporary memory of the computer which stores only for a few times when the requirements of the CPU to store the data, instructions and program due to high traffic of execution. The most accessible and fastest memory of the computer system is the register which stores the 1 to 64 bit of data in the memory. The temporary memory also includes RAM, Cache, register and other types of memory which are known as permanent memory of the computer are disc storage, flash memory, memory card, rom etc. These memories are used for a long time to store the data and database.


System Software

System software is software that controls the input output unit, process unit, memory unit using the program techniques that are applied on the peripheral devices of the whole computer system.

The system software interacts between the user and hardware devices of the computer system.

System software interacts with the interface of graphics which is known as graphical user interface that can command to control the input and output units that are hardware devices of the computer system.

System software is used to install on the computer system because the system software or operating system manages the database of the computer system that is stored into the permanent memory of the computer system for a long time for the user and temporary memory is also used by the operating system on the computer system.

Discuss the role played by the various components of the CPU

Q Discuss the roles played by the various components of CPU? The CPU is the brain of the computer system. All major calculations, manipulations and comparisons are made by the CPU. The CPU is also responsible for activating and controlling the operations performed by all other units of the computer system. The major components of the CPU are: a) Arithmetic Logic Unit (A.L.U.) b) Control Unit (CU) c) Primary Memory Arithmetic Logic Unit (A.L.U.): What is ALU Arithmetic logic Unit? ALU is a part of the CPU. It is a part to calculate the logical term in the CPU where the term refers to an operation of logical type. It also calculates the arithmetic terms in the CPU where the term refers to an operation of arithmetic type. It is used to direct access through the processor controller. The ALU connected to the input and output peripheral system through the bus with the different types of bus. Such as control bus, data bus etc. ALU is a part of the CPU that can calculate the input

About the memory and its Classification of the computer Memory

What are the memories in the reference of computer system? What is Computer Memory?:- The memory is the essential for the computer to store the data, instruction and information. Without memory, computers are not be able to store data, instruction etc. The memory is an essential part of a computer system. It is require by the computer system to store information. Memory can be divided into the following two categories types: i) Primary or Main memory ii) Secondary Memory or Permanent memory In this figure I'll show the classification of the memory of computer system peripheral and architecture of organisations Primary Memory or Main memory:- i) Primary memory is the memory which is fastest memory of the computer. ii) It is a small but relatively fast storage unit that stores data and instruction which are used by the CPU (central processing unit). iii) This type or category of a memory is the main memory of the computer.It is a temporary memory and also we

What are the three main purpose of an operating system?

What are the three main purpose of an operating system? There are three main purpose of an operating system. 1. The first main purpose is User interface between hardware and users. 2. The second main purpose is to operate the internal parts of the computer properly and systematically using binary code system in the form of 0 and 1. 3. The third main purpose is to provide an environment for development of an application software and program to uses the hardware resources of the computer and connected to the computer parts which provides output to the user, the output from application software is very useful for users. Interface between user and hardware device  The operating system uses all types of interface such as command line interface, batch command interface and Graphical User Interface to interact with users to hardware peripheral devices through the monitor screen. Monitor has a big role making interface between hardware and users. Monitor visualization of all types of o
