Answer the following questions:(9x2=18)
A computer is an electronic device, which input data/ instruction, stores and processes it and produces out in the
desired form.
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.

* 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..
