What is a COMPUTER?

• An electonic device that INPUTS and PROCESS data
  to produce OUTPUT and STORES the information
• Composed of HARDWARE and SOFTWARE to RUN
• It is MULTI TASKING

4
What is an input device?
5
INPUT DEVICES

• Input devices are those devices which are used to
  give instructions to computer.
• All these input devices are use to give
  instructions to a computer.
• Without the help of input devices we will not be
  able to give any instructions to computer thus
  computer cannot process for further processing.
• Thus our work will not done without using an
  input device.

PROCESSING DEVICES

• The data to get from the input stage to the
  output stage, something needs to happen to it.
  The data needs to be processed.

19
CPU (Central Processing Unit)

• The CPU is the brains of the computer. The
  central processing unit has to think through
  every instruction generated by your use of the
  computer. These instructions include having the
  arithmetic logic unit (ALU) performing the
  logarithmic calculations to interpret these
  instructions. The processing is done at a speed
  that is nearly impossible for our brains to
  comprehend, let alone actually perform.
• The speeds are referred to with the term
  hertz.The speeds are actually in the millions
  (mega) or billions (giga) of machine cycles per
  second! Think of it as revolutions per minute in
  an engine but a heck of a lot faster!

20
The CPU analyzes every instruction we input and
performs logarithmic calculations.

LGA Processor (Land Grid Array)

PGA (Pin Grid Array)
23
REMEMBER!!

• The more powerful the processing device, the more
  powerful the computer will be.
• The more cores, the better!

24
RAM (Random Access Memory)

• The path of thinking includes volatile and
  non-volatile memory, or temporary and permanent
  memory, respectively.
• Random-access memory (RAM) is volatile, or
  temporary, memory. It wakes up when you turn on
  your computer and holds the information you are
  working on.
• Think of those different windows being open in
  the programs you're using those sit in RAM when
  you're working on them.
• They're right there up front for easy access and
  processing.

RAM (Computer Memory)

OS Compatibility

• OS 32 bit gt 3.5G usable
• OS 64 bit gt installed RAM is usable
• Only Vista 64, Windows 7 64, Windows 8.1 64 and
• Windows 10 64 have ture 64 bit OS

27
REMINDERS!!

• booting is essentially loading the operating
  system in RAM
• The higher the RAM, the better!!

28
OUTPUT DEVICES

• Output devices are those devices which is used by
  computer to display the results.
•  When we give some instructions to computer it
  process the data and display it to a output
  devices.
• Without the help of a output device we cannot see
  the results.

STORAGE DEVICES

• Once data has been entered into a computer and
  processed, it needs to be stored.
• It may only need to be stored temporarily, i.e.
  while it is being used or it might need to be
  stored permanently so that it is available for
  use at a later date.
• A storage device is any media which is used to
  store data.
