2. Is a machine that manipulates data according to a set of instructions

Analog Clock

Oven Toaster

LCD

Calculator

Computer

A computer is a machine that manipulates data according to a set of instructions. It is capable of processing and storing large amounts of information, performing complex calculations, and executing various tasks. Unlike the other options listed, an analog clock simply displays time, an oven toaster is used for cooking food, an LCD is a type of display technology, and a calculator performs mathematical operations. Only a computer has the ability to process data based on instructions given to it.

3. What ALU stands for?

American Language University

Analytic Logic Unselfished

Arithmetic Language and Union

Arithmetic Logic Unit

Arithmetic Language Unit

The correct answer is Arithmetic Logic Unit. The ALU is a fundamental component of a computer's central processing unit (CPU). It performs arithmetic and logical operations on data, such as addition, subtraction, AND, OR, and NOT. The ALU is responsible for executing the instructions of a computer program and manipulating data within the CPU.

4. Considered as the father of computer

John Atanasoff

Bill Gates

Alan Turing

Charles Babbage

Alan Cooper

Charles Babbage is considered as the father of the computer because he designed and conceptualized the first mechanical computer, known as the Analytical Engine, in the 19th century. Although the Analytical Engine was never fully built during Babbage's lifetime, his ideas and designs laid the foundation for modern computers. Babbage's work introduced concepts such as the use of punched cards for input and output, a memory unit, and the ability to perform complex calculations. His contributions to the field of computing were groundbreaking and have had a lasting impact on the development of computers as we know them today.
