Chapters
- 100:00 - 00:03
Chapter 1
- 200:03 - 00:05
Information technology is the use of any computers, storage, networking and other physical device
- 300:05 - 00:07
infrastructure and processes to create, process, store, secure and exchange all forms of electronic
- 400:07 - 00:09
data. There are 4 main ages that divide up the history of information technology
- 500:09 - 00:13
PRE MECHANICAL AGE
- 600:13 - 00:15
Chapter 6
- 700:15 - 00:18
The pre-mechanical age is the age in which there were no kinds of computer systems.
- 800:18 - 00:20
This was a very long time ago, estimated to be around 3000BC.
- 900:20 - 00:22
*Control of fire 500000 BC *Domestication of animals 12000 BC
- 1000:22 - 00:24
*Domestication of plan 8000 BC *Ceramic 7000 BC
- 1100:24 - 00:26
The first ever calculator – the abacus was invented
- 1200:26 - 00:28
MECHANICAL AGE
- 1300:28 - 00:30
Chapter 13
- 1400:30 - 00:31
The Mechanical age developed between 1450 and 1840, the inventors began to use techniques and tools
- 1500:31 - 00:33
to create machines that will perform some tasks.
- 1600:33 - 00:34
The first general purpose computers
- 1700:34 - 00:36
Johannes Gutenberg was a German goldsmith invented the modern printing press with movable metal-type
- 1800:36 - 00:37
ELECTRO-MECHANICAL AGE
- 1900:37 - 00:39
Chapter 19
- 2000:39 - 00:41
The electromechanical age heralded the beginnings of telecommunications as we know it today.
- 2100:41 - 00:42
The first large-scale automatic digital computer in the United States was the Harvard Mark 1 created
- 2200:42 - 00:44
by IBM in 1944. This 8ft x 50ft x 2ft big computer weighed a whopping five tons and had to be
- 2300:44 - 00:46
programmed using punch cards. Its first use was by the Manhattan Project
- 2400:46 - 00:47
Chapter 24
- 2500:47 - 00:49
The electronic age’ begins with Radio Direction Finding introduced at the start of the 20th century
- 2600:49 - 00:50
with radio beacons established to transmit signals, so that a direction-finding antenna could
- 2700:50 - 00:52
determine a bearing to a known transmitter on shore.
- 2800:52 - 00:53
ENIAC (Electronic Numerical Integrator and Computer) was the first electronic general-purpose
- 2900:53 - 00:55
computer. It could solve a large class of numerical problems through reprogramming.
