Difference between data and information.

Data Information Data is a collection of facts Information puts those facts into context. Data are raw and unorganized Information is organized.. Data doesn’t depend on information. Information depends on data. Raw data alone is insufficient for decision making Information is sufficient for decision making Data typically comes in the form of graphs, numbers, figures,…

What are the major operations performed by a computer?

`The basic operations of a computer system include: Controlling and coordinating – Manages all internal computer functions. Accepting data or instructions – Receives input from users. Processing data – Performs calculations and logical operations. Storing data – Saves data for future use. Displaying results – Outputs processed data as information. #ComputerBasics #DataProcessing #Storage #Output #ComputerFunctions…

Aiken, a Harvard graduate student, to solve advanced mathematical physics problems in his research.Aiken’s idea was to use modified commercial technologies, controlled by a central system, to perform complex calculations efficiently. #MarkI #HowardAiken #EarlyComputers #MathematicalComputing #ComputerHistory Are you looking for the Class 9 Computer Science SEBA…

What are the basic differences between the four generations of computers?

`Over the years, many computing devices have been invented to help humans solve various problems. These devices are classified into five generations,representing improvements in size, cost, speed, reliability, and productivity. The evolution of computers includes advancements in both hardware and software technologies.Basic Differences Between the First Four Generations of Computers: Fourth Generation (1971–Present)a) Used Microprocessors…

Write short notes on fifth-generation computers.

`The fifth generation of computers started in 1980 and continues to the present. In this generation, ULSI (Ultra Large Scale Integration) technology replaced VLSI,leading to microprocessor chips with millions of components. These computers use parallel processing and Artificial Intelligence (AI), enabling machines to think like humans.High-level languages like C, C++, Java, and .Net are widely…

What is the purpose of a language processor? Explain the three language processors.

`A language processor (or translator) is a program that converts source code from one programming language to another.It also detects errors during translation. High-level programming languages like C++, Python, and Java require language processors for execution.Types of Language Processors: Example: C, C++, C# Interpreter: Translates and executes the program line by line, immediately running each…

Explain three types of ROM.

`The different types of ROM are: EEPROM (Electrically Erasable Programmable Read-Only Memory): Can be programmed and erased electrically multiple times. PROM (Programmable Read-Only Memory): Can be programmed only once by a user and cannot be erased. EPROM (Erasable Programmable Read-Only Memory): Can be reprogrammed by erasing the stored data using ultraviolet light. #ROM #PROM #EPROM…
