What is the role of Windows Explorer in Windows operating system? The Windows Explorer is a feature of Windows operating system that can be used to view the contents of a computer and network drives in a hierarchical structure. Instead of opening drives and folders in separate windows, Windows Explorer lets one browse through them in a single window. The left side of the Windows Explorer contains the list of drives and folders on the computer and the right side displays the contents of a selected folder. Write a note on all five generations of computers discussing their characteristics. Also give examples of computers belonging to each generation. First Generation Computers (1949-55) The first generation computers used thermionic values (vacuum tubes) and machine language was used for giving instructions. Sd Hack Creator 2 0 Exemption.
PRAVEEN M JIGAJINNI. PGT (Computer Science). MCA, MSc[IT], MTech[IT],MPhil (Comp.Sci), PGDCA, ADCA, Dc. Reference Book. Sumita Arora. DATA REPRESENTATION. Digital technology have found their way into innumerable areas of technology and the far. Which of the two will be appropriate and will derivation from reference books be given marks? I would also like to know the portions deleted from Class XII Computer Sumita Arora textbook. Ajay, Kerala. It is better to use a derivation which is simple and which you follow better. Please refer to the Class XII Computer Science. Write a program to display the following output using a single cout statement: Program = 20. Documentation = 23. Flow Chart = 18 // Program to display newline staements in single cout statement #include iostream.h>void main() { cout = 21 n Flow.
The first generation computers used the concept of ‘stored program’. The computers of this generation were very large size and their programming was a difficult task. Some computers of this generation are being given below: • ENIAC This was the first electronic computer developed in 1946 by a team lead by Prof. Whitesnake Discography Download Kickass there.
Write a short program that asks for your height in centimeters and then convert your height to feet and inches. #include #includeconio.h >void main( ) { clrscr( ); int a,b,c; cout >>a; b = a/30; c = a%30; cout.
Eckert and Mauchly at the University of Pennsylvania in U.S.A. This computer, called Electronic Numerical Integrated And Calculator, used high speed vacuum tube switching devices. Ibert Flute Concerto Program Notes Beethoven.
It has a very small memory and it was used for calculating the trajectories of missiles. It took 200 microseconds for addition and about 2800 microseconds for multiplication. This giant machine was 30X50 feet long, weighed 30 tons, contained 18,000 vacuum tubes, 70,000 resistors, 10,000 capacitors, 6000switches, used 150,000 watts of electricity, and cost S400,000. When ENIAC was built, it was 5000 times faster than the closest competitor, the Harserd MARK-I. • EDVAC The binary arithmetic was used in the construction of a computer called the Electronic Discrete Variable Automatic Computer (EDVAC), completed in 1950. The Von Neumann concept of stored program (in which the machine instructions are stored with data internally) was also applied in EDVAC. With this the operation became faster since the computer could rapidly access both the program and data.
• EDSAC The EDSAC, short for Electronic Delay Storage Automatic Computer was built by Prof. Wilkes at Cambridge University in 1949 and used mercury delayed lines for storage. It also used Neumann concept ‘stored program’. This allowed easy implementation of program loops. • UNIVAC-I Commercial production of stored program electronic computers began in the early 50’s. One such computer was UNIVAC-I built by Univac division of Remington Rand and delivered in 1951. This computer also used vacuum tubes.
