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

Q24 There is a battery on the mother board to

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.
