2.5  Harvard Mark 1 – 1943:

Howard Aiken and Grace Hopper designed the MARK series of computers at Harvard University. The MARK series of computers began with the Mark I in 1944. Imagine a giant roomful of noisy, clicking metal parts, 55 feet long and 8 feet high. The 5-ton device contained almost 760,000 separate pieces. Used by the US Navy for gunnery andballistic calculations, the Mark I was in operation until 1959.  The computer, controlled by pre-punched paper tape, could carry out addition, subtraction, multiplication, division and reference to previous results. It had special

subroutines for logarithms and trigonometric functions and used 23 decimal place numbers. Data was stored andcounted mechanically using 3000 decimal storage wheels, 1400 rotary dial switches, and 500 miles of wire. Its electromagnetic relays classified the machine as a relay computer. All output was displayed on an electric typewriter. By today's standards, the Mark I was slow, requiring 3-5 seconds for a multiplication operation

4.4 Servers / Minicomputers A midsized computer. In size and power, minicomputers lie between  workstations and mainframes. In the past decade, the distinction  between large minicomputers and small mainframes has blurred, however, as has the distinction between small minicomputers and workstations. But in general, a minicomputer is a multiprocessing system capable of supporting from 4 to about 200 users simultaneously.(21

Q24 There is a battery on the mother board to: wwwv.vuzs.info

give power to the processor
Save information when computer is OFF
Help the boot process
Save information when computer is ON

ROM 

ROM is "built-in" computer memory containing data that normally can only be read, not 

written to. ROM contains the programming that allows your computer to be "booted 

up" or regenerated each time you turn it on. Unlike a computer's random access memory 

(RAM), the data in ROM is not lost when the computer power is turned off.  

The ROM is sustained by a small long-life battery in your computer

Q33 First computer that could not only manipulate numbers but also text data as well was: 

ENIAC 
EDVAC 
UNIVAC 1 
Attanasoff-Berry Computer 

ENIAC I (Electrical Numerical Integrator And Calculator). The U.S. military sponsored their research; they needed a calculating device for writing artillery-firing tables (the settings used for different weapons under varied conditions for target accuracy). John Mauchly was the chief consultant and J Presper Eckert was the chief engineer.

Eckert was a graduate student studying at the Moore School when he met John Mauchly in 1943. It took the team about one year to design the ENIAC and 18 months and 500,000 tax dollars to build it. The ENIAC contained 17,468 vacuum tubes, along with 70,000 resistors and 10,000 Capacitors.
