The two major innovations of second generation computers are – Use of solid-state device such as transistors in place of Vacuum tubes and Magnetic core memory. Microprocessor is a complete processor constructed on a single chip using VLSI technology. Intel and Motorola are two popular Microprocessors. This unit controls all hardware operations, i.e., those of input- output units, storage and of the processor itself. It fetches the requisite instructions from main storage, stores it in a number of special registers, interprets the instructions and course the instructions to be executed by giving signals to the appropriate hardware devices. * Speed * Accuracy * Storage and Retrieval * Permanent *Repeated Processing Capability * Quick Decision * Secrecy *Time Factor Operating system is a set of program which forms an interface between user and the computer hardware. A spread is a matrix of rows and columns. The intersection areas of rows and columns are called ‘Cells’. The cells of a spreadsheet are used for entering numbers, texts, and user built formula and functions. A database is a collection of interrelated data stored together with controlled redundancy to serve one or more applications in an optional fashion. A program written by a programmer in a high-level language or assembly language, which is to be converted into machine level language, is called a source program. Answer the following questions:3x4=12 Memory – To store temporarily data and program. Storage Devices- A mass storage device to permanently store data. Input Devices – Input devices such as a keyboard and mouse, so you can enter data and instructions into a computer. Output Devices- Output devices such as monitor, printer or other device that lets you see what the computer has accomplished. Central Processing Unit- The part of the computer that executes instructions. Operating System- A program that lets you access the computers contents and that runs programs. Application- Program that accomplish a specific purpose to help you get your work done. 2. Compiler Interpreter 1 Scans the entire program first and translates Translates the program line by line. it into machine code 2 Converts the entire program to machine Each time the program is executed, every line is code; when all the syntax errors are checked for syntax error and then converted to removed, execution takes place equivalent machine code. 3 Debugging is slow Debugging is faster 4 Execution time is less Execution time is more 3. System Software – The software that controls internal computer operations is called as system software. For example, Operating System, Interpreters, Compilers, Assembler, Utility Programs, etc… Application Software- This is the group of programs, which carry out specific application for user. For example, Payroll systems, financial accounting, word processing, etc..
