Computer uses and functions

Language types Machine and assembly languages A machine language consists of the numeric codes for the operations that a particular computer can execute directly. Machine language instructions typically use some bits to represent operations, such as addition, and some to represent operands, or perhaps the location of the next instruction.

Computer uses and functions

Software Softwarecommonly known as programs or apps, consists of all the instructions that tell the hardware how to perform a task. For example, a program that is designed for the Windows operating system will only work for that specific operating system.

Compatibility of software will vary as the design of the software and the operating system differ. Software is capable of performing many tasks, as opposed to hardware which can only perform mechanical tasks that they are designed for.

Software provides the means for accomplishing many different tasks with the same basic hardware.

Expert Answers

Practical computer systems divide software systems into two major classes: Helps run the computer hardware and computer system itself. System software includes operating systems, device drivers, diagnostic tools and more. System software is almost always pre-installed on your computer.

Allows users to accomplish one or more tasks. It includes word processing, web browsing and almost any other task for which you might install software. Some application software is pre-installed on most computer systems.

Software is generally created written in a high-level programming language, one that is more or less readable by people. These high-level instructions are converted into "machine language" instructions, represented in binary code, before the hardware can "run the code".

When you install software, it is generally already in this machine language, binary, form. System software on right. More system and application software is indicated in the tray at the bottom.A computer port is a connection point or interface between a computer and an external or internal device.

Internal ports may connect such devices as hard drives and CD ROM or DVD drives; external ports may connect modems, printers, mice and other devices. Keyboard is the most common and very popular input device which helps to input data to the computer.

The layout of the keyboard is like that of traditional typewriter, although there are some additional keys provided for performing additional functions. Keyboards are of two sizes 84 keys or / The basic function of computer memory is essentially to store data.

Depending on the type of data it stores and the role it plays in computer operation, however, memory performs several different functions. Although all of these functions involve data storage, RAM, .

Create a program that performs the following functions Uses Create a program that performs the following functions: Uses character arrays to read a users name from standard input. Tells the user how many characters are in his or her name. A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer computers have the ability to follow generalized sets of operations, called programs.

These programs enable computers to perform an .

The system unit is the core of a computer system. Usually it's a rectangular box placed on or underneath your desk. Inside this box are many electronic components that process information.
