Answers
Answer:
1) an electronic machine that can store, find and arrange information, calculate amounts and control other machines.
2) Charles Babbage KH FRS was an English polymath. A mathematician, philosopher, inventor and mechanical engineer, Babbage originated the concept of a digital programmable computer.
3) IPO stands for Input, Output and Process. As the name suggests, IPO cycle is the input and output after process of the data. To get output, u have to first give input and then the input needs to be processed to get your desired result,i.e. Output.
4) RAM and ROM are both types of computer memory. RAM is used to store computer programs and data that CPU needs in real time. RAM data is volatile and is erased once computer is switched off. ROM have prerecorded data and it is used to boot computer.
5) ROM is further classified into 4 types- ROM, PROM, EPROM, and EEPROM.
6) Cache memory is an extremely fast memory type that acts as a buffer between RAM and the CPU. It holds frequently requested data and instructions so that they are immediately available to the CPU when needed. Cache memory is used to reduce the average time to access data from the Main memory.
7) Interpreter translates just one statement of the program at a time into machine code. Compiler scans the entire program and translates the whole of it into machine code at once. An interpreter takes very less time to analyze the source code. However, the overall time to execute the process is much slower.
8) Read-Only Memory (ROM), is a type of electronic storage that comes built in to a device during manufacturing. You'll find ROM chips in computers and many other types of electronic products; VCRs, game consoles, and car radios all use ROM to complete their functions smoothly.
9) The basic difference between analog and digital computers is the type of data they process. ... Digital computer process data which is binary, i.e. in the form of 0 and 1. Analog computers operate on mathematical variables in the form of physical quantities that are continuously varying.
10) System software is used for operating computer hardware. On other hand Application software is used by user to perform specific task. System software are installed on the computer when operating system is installed. On other hand Application software are installed according to user's requirements.
