Introduction:

I have been researching

the question: How has technology
that children use evolved through the past fifty years? I chose
this question because I
personally
like using technology and
find it fun and interesting.



Paragraph 1:

The

first electronic computers are invented in the 1
940s:

They were very expensive and bulky, taking up the space of
an entire room.

1963: T
he U.S., Teletype develops the prototype of the first
inkjet printer: the Teletype Inktronic.

The commercial version of this printer had 40 nozzles fixed to
print ASCI
I characters received by 80 columns on a 1200
-
baud connection.

1967: IBM builds the first floppy disk.

May 1978: Intel launches production of its 16
-
bit processor
8086 running at 4.77 MHz.

It consists of 29,000 transistors in
3
-
micron technology and can a
ccess 1 MB of Ram. His power
is 0.33 MIPS and it costs $ 360.





Paragraph 2:

June 1980: Seagate Technologies announces the first
Winchester hard disk format 5 "25.

1981: Shugart Associates and NCR Partner to work together
on a project interface to conne
ct multiple devices (hard
drives and other), and evolution of the SASI bus owners
solutions at NCR. This project will give birth to the famous
SCSI bus.

1982: Phillips and Sony sign agreement to set a standard
compact disc digital laser reading.

1983: The
makers of music
synthesizers to agree on a communication standard for
connecting them and their instruments with computers: the
MIDI standard.




paragraphe 3:

CD ROM

pour ordinateur au prix de 1000 $.

Octobre 1985

:

86DX

tournant à 16 MHz. Il comporte 275000 transistors et peut
2

4 Go de mémoire. Il est vendu 299 $.

Juin 1986

: Commercialisation du premier microprocesseur
RISC
, le
MIPS R2000
, tournant à 8 MHz et développant une
puissance de 5 MIPS.
