What is a program that tells the computer how do you use a specific device?
Software is a program that enables a computer to perform a specific task, as opposed to the physical components of the system (hardware). Once the software is loaded, the computer is able to execute the software. Computers operate by executing the computer program.
What are the step by step instructions given to the computer regarding a particular job?
Explanation: A set of instructions that directs a computer’s hardware to perform a task is called a program, or software program.
Which of the parts of a computer executes the program instructions?
The CPU. The CPU is the heart of the computer. A program is a sequence of instructions stored in main memory. When a program is run, the CPU fetches the instructions and executes or follows the instructions.
What is instruction and program?
Programs are simply set of instructions or computer code. Instruction are simply order given to computer processor. Programs are collection of software applications especially designed to execute specific task. These are set of machine language instructions that processor understand and perform.
What refers to a computer program?
In imperative programming, a computer program is a sequence of instructions in a programming language that a computer can execute or interpret. In declarative programming, a computer program is a set of instructions. A computer program in its human-readable form is called source code.
How program is executed in computer?
How Does a Program Run? The CPU runs instructions using a “fetch-execute” cycle: the CPU gets the first instruction in the sequence, executes it (adding two numbers or whatever), then fetches the next instruction and executes it, and so on.
What reads Python programs and executes the program instructions?
An interpreter reads a high-level program and executes it, meaning that it does what the program says. It processes the program a little at a time, alternately reading lines and performing computations. A compiler reads the program and translates it completely before the program starts running.
How do computer programs work?
Computer programs work by telling the CPU to access input in a given way, manipulate it in another way, and then present the results as desired. As you type in the words that you wish to, for example, add, the calculator program tells the processor to display them on your computer’s screen.
Which is the first step in programming a computer?
The point is that correct use of the language is the required first step. Then your coded program must be keyed, probably using a terminal or personal computer, in a form the computer can understand.
What do you need to know about computer programming?
You may already have used software, perhaps for word processing or spreadsheets, to solve problems. Perhaps now you are curious to learn how programmers write software. A program is a set of step-by-step instructions that directs the computer to do the tasks you want it to do and produce the results you want.
What’s the difference between software and Ch.1?
(Ch.1) Consists of the step-by-step instructions that tell the computer how to do its work Program Another name for a program. Software Enables the application software to interact with the computer hardware. System Type of computer that is small enough to fit on top of or alongside a desk yet is too big to carry around.
What do you call a set of rules for programming a computer?
Even if you decide that programming is not for you, understanding the process certainly will increase your appreciation of what programmers and computers can do. A set of rules that provides a way of telling a computer what operations to perform is called a programming language.
