Definition of Modern Computer

Inputs, outputs, processes and stores information

Physical: Keyboard, monitor, etc. – are these necessary components?

History of Computers - Long, Long Ago

History of Computers - 19th Century

Joseph Marie Jacquard First stored program -

metal cards Did no computing first computer

Discussion Question

What was the biggest advance that led to modern computers? Electricity Transistor Microchip Data storage

Vacuum Tubes - 1941 - 1956 First Generation Electronic

Computers used Vacuum Tubes Vacuum tubes are glass tubes

with circuits inside. Vacuum tubes have no air inside

of them, which protects the circuitry.

UNIVAC – 1950-51 first fully electronic digital

computer built in the U.S. Created at the University of

Pennsylvania contained 18,000 vacuum

tubes Cost $487,000 ENIAC that preceded it

(late 1940s) weighed 30 tons

Grace Hopper (1906-1992) Programmed UNIVAC Recipient of Computer

Science’s first “Man of the Year Award”

First compiler for a computer programming language, led to COBOL

First Transistor

Used Silicon (semiconductor) developed in 1948 won a Nobel prize on-off switch 2nd Generation Computers

used Transistors, starting in 1956

Second Generation – 1965-1963

1956 – Computers began to incorporate Transistors

Replaced vacuum tubes with Transistors

Integrated Circuits

Third Generation Computers used Integrated Circuits (chips).

Integrated Circuits are transistors, resistors, and capacitors integrated together into a single “chip”

First one made by Texas Instruments in 1958

Operating System

Software – Instructions for Computer ‘Operating system’ is set of instructions

loaded each time a computer is started ‘Program’ is instructions loaded when

needed

Third Generation – 1964-1971

1964-1971 Integrated Circuit Operating System Getting smaller, cheaper

The First Microprocessor – 1971

The 4004 had 2,250 transistors

four-bit chunks (four 1’s or 0’s)

108Khz

Called “Microchip”

What is a Microchip?

Very Large Scale Integrated Circuit (VLSIC) Transistors, resistors, and capacitors

4004 had 2,250 transistors Pentium IV had 42 MILLION transistors

Each transistor 0.13 microns (10-6 meters)

4th Generation – began 1971

MICROCHIPS! Getting smaller and smaller, but we are

still using microchip technology

Birth of Personal Computers - 1975

256 byte memory (not Kilobytes or Megabytes)

2 MHz Intel 8080 chips Just a box with flashing

lights cost $395 kit, $495

assembled.

68000 Microchip processor first commercial computer with

graphical user interface (GUI) and pointing device (mouse)

The first GUI?

XEROX PARC

Today: 2014

Traditionally Intel divides the Core platform into three segments--Core i3 at the low end, Core i5 for the midrange, and Core i7 at the high end.

Following that designation is a model number. You may also see a suffix at the end of the model number: K for unlocked processors, S for “performance-optimized” processors, or T for “power-optimized” processors. The S and T variants are generally for OEM use only--expect to see them in desktops and laptops on retail shelves. An unlocked, higher-end Ivy Bridge CPU, for example, could be named the Intel Core i7-3770K.

1990s: Pentiums and Power Macs

Early 1990s began penetration of computers into every niche: every desk, most homes, etc.

Faster, less expensive computers paved way for this Windows 95 was first decent GUI for “PCs” Macs became more PC compatible - easy file transfers Apple effort at licensing OS (Power Computing) Mac conversion to Intel chip Prices have plummeted

$2000 for entry level to $400-$500 $6000 for top of line to $1000-$1500

21st Century Computing

Great increases in speed, storage, and memory

Increased networking, speed in Internet Broadband growth Netbooks / iPad / tablets Smart Phones Impact of touch technology 3G to 4G (3-5 Mbps / 8-10 Mbps)

What’s next for computers? Use your imagination to come up with what the

coming years hold for computers. What can we expect in two years? What can we expect in twenty years?

Voice interface? Cloud computing growth True ubiquity? Interface to almost all activities?

Developing TechnologiesDeveloping Technologies Bluetooth

Name comes from Harald Bluetooth, king of Denmark in the late 900s

There are lots of different ways that electronic devices can connect to one another--Component cables, Electrical wires, Ethernet cables, WiFi, Infrared signals…

Bluetooth is essentially a networking standard that works at two levels:

It provides agreement at the physical level -- Bluetooth is a radio-frequency standard;

AND, it provides agreement at the protocol level, where products have to agree on when bits are sent, how many will be sent at a time, and how the parties in a conversation can be sure that the message received is the same as the message sent. (cell phone, GPS, PDA--Starfield example)

Allows wireless carriers to offer video content without taking up much needed bandwidth in their cellular network.
