What sets of instructions do computers use to process data? - Computer Programs
Computers nowadays are used in almost every field. Computers can be instructed to perform a variety of individual functions. A set of instructions that tells a computer what to do is called a program. Today, more than 10,000 application programs are available for use on personal computers. They include such popular programs as word processing programs, spreadsheet programs, database programs, and communication programs.
The instructions that computers follow are located in programs. Programs are stored on media such as CDs, DVDs, floppies, USB drives, and hard drives. When a program is loaded, it is copied into RAM, and the CPU executes the instructions inside of the software out of RAM.
n multitasking, only one CPU is involved, but it switches from one program to another so quickly that it gives the appearance of executing all of the programs at the same time.

The programs (instructions) are saved on a computer's hard disk; to actually execute the instructions, they are copied into RAM. From there, they are basically fetched, one instruction at a time, into the CPU, where they are executed.
The more common name for programs or instructions is "software." Software encompasses a wide range of applications and systems that enable computers and devices to perform specific tasks. This includes everything from operating systems to applications and utilities that enhance functionality.
Yes, that is correct. The "programs" or "software" are actually instructions, for the computer to carry out different tasks in a specified way.
When dealing with computers, there are usually specific instructions given to give you an easy time when using certain programs or software. These step by step instructions are normally referred to as tutorials.
A Computer Program (also software, or just a program) is a sequence of instructions written to perform a specified task with a computer. A computer requires programs to function, typically executing the program's instructions in a Central Processor. The program has an executable form that the computer can use directly to execute the instructions. The same program in its human-readable source code form, from which executable programs are derived enables a programmer to study and develop its algorithms.
A CPU (Central Processing Unit) is the main component of a computer that carries out instructions from programs by performing basic arithmetic, logic, control, and input/output operations specified by the instructions. It acts as the brain of the computer, executing tasks and coordinating the operation of various system components.
I'm not sure what you are asking. Third generation computers were the first to have fully functional OSs supplied by the manufacturer. They were also the first to come with supervisor/user modes where some instructions could only be executed by the OS in Supervisor mode, user programs would error out if they executed such instructions directly. This protected the OS and I/O devices from defective user code. To perform any I/O or interact with other programs the user programs had to call OS service routines to coordinate the actions and execute the required Supervisor only instructions.
