Subject- Introduction to Computer Fundamental and PC Software UNIT-I Introduction A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data. You can use a computer to type documents, send email, and browse the Web. You can also use it to handle spreadsheets, accounting, database management, presentations, games, and more. In World War II, mechanical analog computers were used for specialized military applications. During this time the first electronic digital computers were developed. Computer was developed by CHARLES BABBAGE. He is also known as Father of computers. All types of computers consist of two basic parts: Hardware is any part of your computer that has a physical structure (Tangible), such as the computer monitor or keyboard. Software is any set of instructions that tells the hardware what to do. It is what guides the hardware and tells it how to accomplish each task. Some examples of software include web browsers, games, and word processors such as Microsoft Word. INPUT Processing Unit Output Unit Memory Organization of a Computer Computer can also be defined in terms of functions it can perform. A computer can i) Accept data, ii) Store data, iii) Process data as desired, iv) Retrieve the stored data as and when required and v) Print the result in desired format. Characteristics of computer:- Speed Diligence No Feeling Accuracy Versatility Storage Power of No IQ Remembering Block diagram of Computer:- 45, Anurag Nagar, Behind Press Complex, Indore (M.P.)

Input: this is the process of entering data and programs into the computer system. 2. Control Unit (CU): The process of input, output, Control Unit (CU): The process of input, output, processing and storage is performed under the supervision of a unit called 'Control Unit'. It decides when to start receiving data, when to stop it, where to store data, etc. It takes care of step -by-step processing of all operations inside the computer. 3. Memory Unit: Computer is used to store data and instructions. 4. Arithmetic Logic Unit (ALU): The major operations performed by the ALU are addition, subtraction, multiplication, division, logic and comparison. 5. Output: This is the process of producing results from the data for getting useful information. The ALU and the CU of a computer system are jointly known as the central processing unit (CPU). You may call CPU as the brain of any computer system. Evolution of the Computer : The first counting device was the abacus, originally from Asia. • 1600s : John Napier discovers logarithms. • 1642 : Blaise Pascal, a French mathematician and philosopher, invents the first mechanical digital calculator using gears, called the Pascaline. • 1804 : Joseph Marie Jacquard used punch cards to automate a weaving loom. • 1812 : Charles P. Babbage, the "father of the computer", discovered that many long calculations involved many similar, repeated operations. Therefore, he designed a machine, the difference engine which would be steam-powered, fully automatic and commanded by a fixed instruction program. In 1833, Babbage quit working on this machine to concentrate on the analytical engine. • 1840s: Augusta Ada. "The first programmer" suggested that a binary system should be used for storage rather than a decimal system. • 1906 : The vacuum tube is invented by American physicist Lee De Forest. • 1939 : Dr. John V. Atanasoff and his assistant Clifford Berry build the first electronic digital computer. Their machine, the Atanasoff-Berry-Computer (ABC) provided the foundation for the advances in electronic digital computers. • 1945 : Dr. John von Neumann presented a paper outlining the stored-program concept. • 1947 : The giant ENIAC (Electrical Numerical Integrator and Calculator) machine was developped by John W. Mauchly and J. Presper Eckert, Jr. at the University of Pennsylvania. It used 18, 000 vacuums, punch-card input, weighed thirty tons and occupied a thirty-by-fifty-foot space. • 1949 : Maurice V. Wilkes built the EDSAC (Electronic Delay Storage Automatic Computer), the first stored-program computer. EDVAC (Electronic Discrete Variable Automatic Computer), the second stored-program computer was built by Mauchly, Eckert, and von Neumann. • 1950 : Turing built the ACE, considered by some to be the first programmable digital computer.

Components of the Von Neumann Model 1. Memory: Storage of information (data/program) 2. Processing Unit: Computation/Processing of Information 3. Input: Means of getting information into the computer. e.g. keyboard, mouse 45, Anurag Nagar, Behind Press Complex, Indore (M.P.) Ph.: 4262100, www.rccmindore.com 3 B.Com 1st Sem. Subject- Introduction to Computer Fundamental and PC Software 4. Output: Means of getting information out of the computer. e.g. printer, monitor 5. Control Unit: Makes sure that all the other parts perform their tasks correctly and at the correct time.
