#Components of hardware software and peopleware of computer professional#
Nowadays software is becoming more and more user-friendly easy to use even by non-computer professional users. Software controls the hardware, uses it, and forms an interface between the computer and its user. It should be noted that the hardware developments are dependant on well-written and well-formed software. Often programmers in large corporations work in teams, each programmer focusing on a specific problem of a total project. Software is written by computer programmers. Programming of a computer is performed by specialists. When a soft ware is loaded into a computer it automatically programs the computer to perform a specific task. Most modern programs exist independently of the computer. Software is often stored in a computer’s memory. The hardware and software systems of a computer work together. Without a software a computer does not operate. A computer’s operating system is the software. Without a program a computer is nothing but potential. By using several thousand microprocessors the Thinking Machine outperforms many of today’s supercomputers. And there already exists one such design called Thinking machine. But the problem could be solved much more quickly by the use of a great number of processors simultaneously working on the given task. Almost all of today’s computers process information one element at a time. These physical parts and all their physical components are called hardware.Īs for the problem of hardware development, specialists believe that radically new computer designs are absolutely necessary. These four parts are linked by a communication network, or a bus. But in practical usage the term “computer” usually refers to digital computers.Ī digital computer is a complex system of four fundamentally different elements: a central processing unit, input devices, memory-storage, and output devices. In analog computers problems are solved by considering changing data (electric current, voltage, resistance, pressure). There exist also hybrid types of computers that combine some of the properties of both analog and digital computers.

There exist two fundamentally different types of computers: analog and digital ones.
