For, While and Do ....While

. 1) What is looping? Describe “for”, “while” and “do-while” loops with appropriate examples. Answer: Looping statements or Iterative Statements 'A loop' is a part of code of a program which is executed repeatedly. A loop is used using condition. The repetition is done until condition becomes condition true. A loop declaration and execution can be done in following ways. • Check condition to start a loop • Initialize loop with declaring a variable. • Executing statements inside loop. • Increment or decrement...

Generation of Computer

GENERATIONS OF COMPUTERS Computer generations classification is mainly based on the basic devices used. Also, the considerations are the architecture, languages, modes of operation,  in different periods of time. Based on the period of development and the features incorporated, the computers are classified into different generations- First generation to Fifth generation. This is called the computer generation. The classification and time periods are given below: 1.) First Generation Computer (1945-1955) First generation computers...

Electronic Computer Era

# Explain the Electronic computer era in details. The Electronic Computer Era The computers of this age are developed by using electronic components like a vacuum tube, transistors IC, VLSI, etc. These computers are smaller, faster and more reliable. The ENIAC (1943-1946) In 1946, John W. Mauchly and J.presper Eckert constructed ENIAC (Electronic Numerical Integrated and Calculator), at the Moore School of Engineering of the University of Pennsylvania. USA ENIAC was the first popular general purpose all electronic digital computers....

Electro-Mechanical Era

2.) Explain The Electro-Mechanical Era in chronological order. The calculator of this age was developed by using mechanical and electronic component vacuum tube. Successful general purpose mechanical computers were built, in the 1930s. Konrad Zuse developed mechanical computer, the Z1, in 1983 in Germany. The Mark I Computer (1937 - 1944) A Professor of Physics, Howard H. Aiken designed a general purpose mechanical computer at Harvard University and IBM Automatic Sequence Controlled Calculator (IBM ASCC). It was the first fully automatic calculating...

Mechanical Era of computer History

1. Describe The Mechanical Era (zeroth generation) of computer history in chronological order. Ancient people lived on the earth for centuries without counting. Then, they started to count their ten fingers. It becomes so difficult to live and to remember anything. These phenomena were gradually replaced by the use of stones, counting notches on sticks or marks on walls. The different generations are described below which has helped the humans for keeping records with the passing of time. 1.) The Mechanical Era (Zeroth generation) The calculator...
