Integrated circuits An integrated circuit is a circuit in which some transistors are fabricated any single piece of semiconductor material it is a group of electronic components like a transistors resistors and capacitors connected by means of voice it is also called the ship computers are rebuild using two kinds of IC chips they are Logic chips Memory chips

Logic chips Logic chips are used in the arithmetic logic unit where calculations are carried out

Memory chips are used to in the memory to hold data and instructions Things to remember The system unit is the main part of the computer because CPU is placed inside it The motherboard is a printed circuit board or PCB where are all the electrical circuits are printed The power supply unit is a device which converts high voltage current to voltage current required by the components of PC Main memory determine the amount of data that can be stored in the computer as well as the amount of data that it can process

Computer software Computer software is a set of programs that make the hardware perform a set of task in particular order hardware and software are complementary to each other both have to work together to produce mean full results computer software is classified into two broad categories system software and application software . System software System software consists of a group of programs that control the operations of a computer equipment including functions like managing memory managing peripherals loading store in and an interface between the application programs and the computer MS Dos Microsoft disc operating system and also Unix are examples of system software. Software that can perform a specific task for the user such as the word processing accounting budgeting or payroll fall under the category of application software word processor spreadsheets database management system are all examples of general purpose application software.
