Why do computer need instructions?

Computers need to be programmed to tell them how to make decisions. They have to know what to do in many different situations. They have to make a choice or a ‘selection’. Being able to run different code in different situations is what makes computer programs so powerful and flexible.

What is a instruction in computer?

An instruction is an order given to a computer processor by a computer program. In a computer’s assembler language, each language statement generally corresponds to a single processor instruction.

Can computer work their own?

Computer : is an electronic device that operates (works) under the control of programs stored in its own memory unit. It works on the data using the instructions issued, means that, the computer cannot do any useful job on its own. It can only work as per the set of instructions issued.

Can computer take its own decisions?

Computers cannot take decisions on their own because they do not possess all the essentials of decision-making.

Who can work without instruction?

A computer (specifically the CPU, or central processing unit, within the computer system) needs instructions in order to do even the simplest things. Without instructions, it can’t do anything. Just to boot your computer requires executing many many instructions.

How does computer is able to execute an instruction?

The program which is to be executed is a set of instructions which are stored in memory. The central processing unit (CPU) executes the instructions of the program to complete a task. The major responsibility of the instruction execution is with the CPU. The instruction execution takes place in the CPU registers.

Who gives instructions to a computer?

The instructions given to the computer is given by the human using a keyboard or any other input device. The computer uses a software or OS to interpret these instructions which are also programmed by the human to translate the user commands.

What type of work can a computer do?

A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data. You may already know that you can use a computer to type documents, send email, play games, and browse the Web.

Can a computer make a decision on its own when no instructions are given to it why?

A computer can only make a decision if it has been instructed to do so. In some advanced computer systems, there are computers that have written the instructions themselves, based on other instructions, but unless there is a “decision point”, the computer will not act on its own volition.

What is it called when you work without supervision?

A person who doesn’t need a boss to look over his shoulder is self-motivated. A person who doesn’t need a boss to give instructions for each task is a self-starter. A person who can be or has been trained quickly and thereafter is able to function without supervision is a quick learner.

Is it possible to program without an operating system?

Yes. But you have a lot of work to do. Without an operating system using and enforcing a standard, systematic approach to running the computer, you’re put in the position of writing code (or programs) that must tell the computer exactly what to do.

Is it possible to work on electronics without any software?

If the hardware is non programmable device such as Analog amplifier, filter, flip flop, etc it does work without any software. If you are good in electronic circuits, you can design many circuits for various use cases which doesn’t require any software. I used to play with electronic hobby kits which never required any software.

What can I do in it without a degree?

Here are 10 IT jobs you can get with no degree: Computer support specialist. Junior data analyst. Help desk analyst. Computer Programmer. Web developer. IT manager. Computer software engineer. Cybersecurity specialist.

Is it possible to run your own code on your computer?

It’s also possible to run such code from the network (network boot option). Also it is possible to run code like an extension BIOS, well, in fact CPU juts jumps to user code and neither BIOS nor OS works but user code does. Here are examples of some Russian security PCI boards, which run its own program before any OS can take a control.
