• 3000 BC - Invention of the abacus
• 1621 - Slide rule is invented (used until mid
  1970's)
• 1800 - First punch cards for storing data are
  invented by Jacquard.
• 1820s - Difference Engine (Charles Babbage)
• 1943 - First electronic general purpose computer,
  the ENIAC, is invented
• 1944 - First stored program computer is invented,
  the EDVAC
• 1948 - First commercial computer, the UNIVAC,
  created

• 1948 - invention of transistor led to second
  generation of computers
• 1958 - At Texas Instruments, Jack Kilby builds
  the first integrated circuit
• Computers based on the first generation
  integrated circuit technology became known as the
  third generation of computers
• 1970s - Development of the microprocessor
• Fourth Generation of computers (PCs) are based on
  the microprocessors
• late1980s - SMP (symmetric multiprocessing)
  systems use multiple microprocessors - Fifth
  Generation of computers
• late1990s - Standard High-Volume (SHV) server
  motherboard, system design building block
  containing all the components necessary - from
  processors and memory to SMP, and I/O-bus
  hardware

Computer - an electronic device that has the
ability to store, retrieve, and process data, and
can be programmed with instructions that it
remembers.

Keyboard, mouse, Video camera, etc
Printer, speech, etc
Operating System - the main control program of a
computer that schedules tasks, manages storage,
and handles communication with peripherals. The
operating system presents a basic user interface
when no applications are open, and all
applications must communicate with the operating
system.

CPU (Central Processing Unit) controls the
operation of a computer. Units within the CPU
perform arithmetic and logical operations and
decode and execute instructions.
Microprocessor - a computer with its entire CPU
contained on one integrated circuit.
Digital Machine Uses Binary System
CODEC - 1.Coder/decoder. A device that converts
analog signals to digital to be read by a
computer or transmitted over a network, and
converts the digital signals back to
analog. 2.Compression/decompression. A two-step
process used on very large multimedia files.
Files are compressed, then expanded to their
original size in order to play them on the
computer.

Globalisation

• Partnerships
• Alliances
• Mergers

Branches are scattered everywhere

• Decisions are to be made on spot
• Not to wait for the head office
