A computer program is a series of instructions that tell a computer how to carry out a task.
Operating system is interface between computer user and computer hardware.
A basic instruction that can be interpreted by a computer generally has an operation code (opcode) that specifies the action to be performed, such as addition or data movement. It may also include operands, which are the data or memory addresses involved in the instruction. Together, these components enable the computer's processor to execute tasks efficiently.

Fetching an instruction refers to the process in which a computer's CPU retrieves an instruction from its memory to execute it. This is the first step in the instruction cycle, where the program counter points to the address of the instruction to be fetched. Once retrieved, the instruction is decoded and executed, allowing the CPU to perform the specified operation. This process is fundamental to how computers execute programs and manage tasks.
The instruction cycle is also known as the fetch-decode-execute cycle. It refers to the process by which a computer retrieves an instruction from memory, interprets it, and then executes it. This cycle is fundamental to the operation of a CPU, enabling it to perform tasks and run programs efficiently.

Writing code is known as programming.
The component that interprets each instruction issued by a program and initiates the corresponding action is known as the Central Processing Unit (CPU). The CPU processes instructions from software, executing tasks by performing calculations, moving data, and controlling other hardware components. It acts as the brain of the computer, coordinating all operations to ensure the program runs smoothly.
It is useful to record the mouse movements on your computer if you carry out a lot of repetitive tasks. By recording the movements you can replay the movements to carry out the action for you. Saving you time and relieving the repetition.
Operating system tools are used to carry out certain tasks on your computer and keep your computer running smoothly. Tools include disk defragmenter, disk scan and disk cleanup.
Its main function is to execute instructions stored in a memory, which allows system to perform various tasks. the cpu retrives instruction from the memory, decodes them and then executes them. this process is known as the fetch decode execute cycle. The cpu is responsible for performing the majority of the calculations and logical operations as required by a computer. it also manages the systems memory, input/output devices and communication with other devices in the system. additionally the cpu also acts as the control center that cordinates and synchronize the activities of other components in the system. in summary the main function of a cpu is to execute instruction of the computer program. in summary the main function of cpu is to execute instruction of the computer program which in turn allows the system to perform various tasks.
