A set of instructions or programs and reusable instructions or routines or functions used to program, operate and perform a specific practical task in an electrical machine or computer (including a computer management system or operating system) collectively known as computer software (English): Computer software), called computer instructions or computer hardware. In contrast, the electronic, electrical, magnetic and all other visible and tangible physical parts of a computer are collectively called computer components or computer hardware.

Computer instructions or programs are not written in the normal written form of human spoken language. Rather, they are written in a special type of artificial symbolic (but human-understandable) language, called an instruction-sequence language or programming language. Symbolic instructions written in a programming language are called source code or source code. But machines or computers cannot process this source sign language. So the source code is translated into an artificial language called a machine language by another program called a compiler, and the resulting machine code can be "understood" or processed by a machine or computer and execute the instructions contained in it.

Instruction material or software is usually stored in long-term memory on a hard disk or as a magnetic signal on a hard disk. When an instruction sequence or program needs to be executed, the computer's main processing unit (central processing unit) "reads" it from long-term memory and stores a copy or copies of the instruction sequence in the computer's temporary memory or random access memory (random access memory). ) and execute or "run" the sequence of instructions or program from there. They are deleted from temporary memory when the program ends. However, some instructions reside permanently in a special type of memory called read-only memory. Such instructions are called "fixed instructions" or firmware or hard software.

Software is the amount of data or programs through which a computer is operated. But you can't run a computer without software. Let's not talk more, let's know the software in detail.

Without the software, the computer is completely immobile. Let me explain this to you with an example. Web browser is an application software and this web browser is rhyme, but you could not read my article, that is, without software, you could search, read or download any information on web browser. no Hope you understand how important the software is as a computer component.
