Differentiate between Analog and Digital Computer with suitable examples The difference between Analog and Digital computers are as follow: Analog Computer (1) Information is represented by the magnitude of continuously varying signals (2) They are not accurate as digital computers. (3) Things done in analog computer can be done in digital computer. (4) Analog computer is used for scientific research only and it is rarely used. (5) It needs much mathematical background to use and understand (6) Plesely, Speedometer, thermometer, seismograph etc Digital Computer Information is represented by electronic pulses( "On" or "Off") They are very much accurate Things done in digital computer cannot be done in analog computer Digital computer is widely used even for general purpose There is no need of much mathematical background to use and understand Calculater, video games etc.

Explain about the generation of Programming Language Ans: According to the development and modification in programming language, the generation of programming language can be described as : (i) Machine language: The history of programming language starts with machine language. The only command that computer can understand is the machine code or '0' and '1'. Machine language consists of bits of 0s and 1s that electrically set the switches, where 0 represents off (or low) and 1 represents on (high voltage). Initially the program used to be written using this language. (ii) Assembly language: A programming language developed to replace machine code o and 1 is known as assembly language. It consists of many symbols and abbreviation. The program written using this language is converted into machine code by Assembler. The drawback of this language is that the program written for one computer does not work in another computer and it was a tough job for the programmer to rememb

#) What do you mean by generation of computers? What technology characterizes the 2nd and 3rd generation of computers? How the limitations of 2nd generation computer were addressed by the 3rd generation? Ans: Evolution of computer is divided into five phases (generation) under the development and improvement in different factors is known as generation. and some of the important factors are: Speed , Storage capacity, Reliability, Cost reduction SECOND GENERATION 1959-1964 Used transistors (invented-1947, used in computer-1959, electronic switching device) Transistor=transfer + resistor( Bell Lab-> John Burdeen, Walter Brattain and William Shockley-> Nobel prize 1956 Speed (micro seconds) High level language i.e. COBOL, BASIC Magnetic core memory (as internal storage) Magnetic tapes for secondary storage Input & output devices faster IBM 1400, 400 series, NCR 315, Smaller (How?), cheaper, more reliable Specialized (scientific, non-scientific) THIRD GENERATION 1965-1974 IC( by J

What is System software? Describe the function of it. It is Interface between hardware and Application Software (or User). CPU coordinates with other parts in computer System due to system Software. And the jobs of it are: To load itself in the memory (RAM) and it is called booting. To load User program in the memory To load Data through keyboard to RAM To Interpret the program instructions one at a time To display output (gives instruction to display) on the screen (printer too) To read /write data from/into storage device. To control hardware (activate when needed) To act as a manager To check input/output devices available

#) What is software? Ans: Software is abstract machinery that instructs the computer hardware to perform the activities. It provides an interface or link between computer hardware and user. Software can be treated as soul of computer Software is a module or series of instructions integrated together. A single job assigned by the user can be broken down into .many software instructions. It is a thinking technology. Success of Hardware depends upon the power and capabilities of its supporting software. Types · System software · Application software · Utility software

What are the different stages of software development? Explain with examples why a program development requires systematic methods. What are the initial steps of program design? Why should user be involved throughout the system development life cycle? Can you think of some specific examples of what might happen if the users are not involved? Ans: A set of elements work together for a common goal is known as system i.e. education system, Police Security System, Banking System etc. Raw data is originated, processed / transmitted and received as information and the integration of it is known as information system. To manage the existing information system by using computer is Computerized Information System(CIS). To manage Information System(MIS) we must know the structure of an organization. The structure of an organization can be leveled top to bottom as STRATEGIC --->TACTICAL ---> OPERATIONAL ---> TRANSACTION. And the data/information flow is more structured in lower level of
