Concept Of Hardware and Software

Concept Hardware and Software

The concept of hardware and software is very simple in the computer. A computer system is made of two parts- Hardware and Software.

Hardware

All physical parts of the computer can be said as hardware of the computer. For example, all the input and output devices from the parts of the computer.

If we think of computer as a living being, then the hardware would be the body. Since the computer hardware is a part of a machine, it can only understand two basic concepts: 'ON' and 'OFF'. The 'ON' and 'OFF' concepts is called binary. Computer software was developed to tell the computer hardware what to do.

Software

The computer hardware cannot think and make decision on its own. The hardware needs a software to instruct what to be done.

A program is a set of instruction that is arranged in a sequence to guide a computer to find a solution for the given problem. The process of writing a program is called programming.

Cache Memory

Cache Memory Cache memory is an intermediate form of storage between registers and the primary memory. It is used to store instructions and data that are repeatedly required to execute programs thereby improving the overall system speed and increase the performance of the computer. Keeping frequently accessed data and instructions in the cache avoids accessing the slower primary memory. Working of the Cache Memory When a program is being executed and the CPU wants to read data or instructions, then the following steps will be performed: CPU first checks whether the data or instruction is available in cache memory. If it is not present, the CPU reads the data or instructions from the main memory into the processor registers. The CPU also copies it into the cache memory. When the same piece of data/instruction is needed, the CPU reads it from the cache memory instead of the main memory

Generation Of Computers Explain

  Generation Of Computers Generation of computers  can be understood by looking into five generations. With each new generation of computers, there had been advancement in computer technology. The circuitry became smaller with enhanced speed, less consumption of power, and efficient memory Therefore, each generation of computer is characterized by a major technological development that has drastically changed the way in which computers operate First Generation (1942-1955) Hardware Technology-  First generation computers  were manufactured using thousands of vacuum tubes Software Technology-  Programming was done in machine language or assembly language. Used for - Scientific application Exmaples  - ENIAC,EDVAC,EDSAC,UNIVAC I,IBM 701 Highlights They were the fastest calculating device of those times. Computers were too bulky and required a complete roomm for storage. Highly unreliable as vacuum tubes emitted a large amount of heat and burnt frequently. Requi...

Classification of computers software

CLASSIFICATION OF COMPUTER SOFTWARE Computer software is written by programmers using a programming language. The programmer writes a set of instructions (program) using a specific programming language. Such programs are known as the source code. Another computer program called a compiler is then used on the source code, to transform the instructions into a language that the computer can understand. The result is an executable computer program, which is another name for software. Examples of computer software include the following: Driver software, which allows a computer to interact with hardware devices such as printers, scanners, and video cards. Educational software, which includes programs and games that help in teaching and providing drills to help memorize facts. Educational software can be used in diverse areas, from teaching computer-related activities like typing to subjects like chemistry. Media players and media development software, which are specifically designed to play ...
