Communication types

Copy into Word, then research the code or method of communication used.

Communication Type	What was it?	When was it used?	What did it replace?	What replaced it?
The Pony Express 24 hours...rain or shine! MAP	The Pony Express was a mail and packaging delivery system	1860s	It replaced newspapers being sold by 1 person in the streets	The telegraph made a faster and cheaper method to send information.

ASCII	A type of format for text that is commonly used in computers	1960s	It was a way to display text on the screen	It was replaced by Javascript and coding

This is the Challenge! Copy the code representations for the word Pat.

Alphabet	ASCII Binary	ASCII Octal	Semaphore	Morse Code
P	01010000	020	LH up; RH out	Dot, Dash Dash Dot
A	01000001	001	LH down; RH low	Dot Dash
T	01010100	024	LH up; RH high	Dash

Computing History

The Premechanical Age: 3000 B.C. - 1450 A.D. People Computing Devices Pre-Historic People and Ancient Civilization The Abacus, First recorded computing tool found in china The Mechanical Age: (Before Electricity) 1450 - 1840 People Computing Devices An French Mathimatician The Pascaline, the first mechanical calculator invented by Blaise Pascale The Electromechanical Age: (With Electricity) 1840 - 1940. People Computing Devices Invented by J. Presper Eckert and John Mauchly ENIAC, was the very first computer ever invented. The Electronic Age: 1940 - Present. People Computing Devices Modern People The Modern Computer Part 2:  Page 2 Generations of Computers since 1940  Put an image of the electronic components in the chart Generation Examples of Computer Electronic Components Years Used for? Size Interesting fact about each 1  Vacuum Tubes Invented in 1904 Old Technology like Old Radios As big as 2 fingers They turn on and off 2  Transistors 1926 It is used as a switch for many devices Small Transistors are usually made of silicon or germanium 3  Chips (Integrated Circuits) 1949 they are used in computerrs, they are found inside the motherboard. They are used as timers, microprocessors, memory and many other uses. Small Transistors are already built into the motherboard so you don't have to buy them. 4  Microprocessors Computers on  a chip 1971 they are used as the brain of the computer, they process information and organize them.  Fits in your hand Microprocessors can do alot of things from simple to complex. Like adding two numbers, or copying a series of letters and numbers.  5.  Networking Parallel Computing Fibre Optics Fibre Optics(1790) Parallel Computing (1969) A bunch of computers that work together to preform 1 or more tasks.  Fits in an entire room Parallel Computers are usually used by companies, and are not acessable or affordable to the public.
