2. Task 1
Learn about computer
• What is IT and IT workshop
• What is Computer and block diagram of Computer
• Identify Internal Computer parts
• Specification for each part of computer
• Specification of desktop computer

3. What is IT and IT workshop
• Information technology is the use of computers to store, retrieve,
transmit, and manipulate data, or information, often in the
context of a business or other enterprise. IT is considered to be a
subset of information and communications technology
• A workshop is building which provides both the area and tools
that may be required for the manufacture or repair of
manufactured goods

4. What is Computer ?
• Computer is an advanced electronic device that takes raw data as
input from the user and processes these data under the control of set
of instructions (called program) and gives the result (output) and
saves output for the future use. It can process both numerical and
non-numerical (arithmetic and logical) calculations

5. Block diagram of Computer

6. Input Device
• Accept(or reads) the raw data
and instructions from the
outside world
• Convert it input of raw data &
instruction that the computer
acceptable form(understand )
• Supply the converted raw data
to the computer system for
further processing

8. Output Device
• Accepts the raw data results
produced by the system, which
are in coded form and hence
• Convert these coded results to
human acceptable (understand
it)
• Supplies the converted results
to outside it like (VDV) etc.

9. Identify Internal & External Computer parts
• PC Case (cabinet)
• CPU Internal Part
• peripheral devices

10. Computer(CPU Internal Device) parts
• Motherboard
• Power supply
• Processors(cpu)
• RAM Modules
• Hard Drive
• Optical Drive
• Etc.

11. Motherboard
• A motherboard is the main printed circuit board (PCB) in a computer.The
motherboard is a computer's central communications backbone connectivity
point, through which all components and external peripherals connect. ...
Additional components can be
added to a motherboard through
its expansion slots
•Processor Socket. ...
•Power Connectors. ...
•Memory Slots. ...
•Video Card Slot. ...
•Expansion Slots. ...
•IDE and SATA Ports. ...
•BIOS Chip and Battery
•Heat sink(Northbridge)

12. Power supply SMPS
• SMPS stands for Switch-Mode-
Power-Supply.They are used in many
places in a computer. In a modern
computer, there is a SMPS that takes
rectified AC input from the wall,
performs power factor correction and
then converts the output into one or
more lower voltage DC outputs

13. Processors(cpu)
• A processor or micro-processor is the 'brains' of a computer system. It is the
processor that controls the working of all of the hardware and software.
• The processor is sometimes referred to as the Central Processing Unit (CPU)
• The Four Primary Functions of the CPU:-
•Fetch Each instruction is stored in
memory and has its own address.
•Decode All programs to be executed are
translated to into Assembly instructions.
•Execute While executing instructions the
CPU can do one of three things: Do
calculations with its ALU, move data from
one memory location to another, or jump
to a different address.
•Store The CPU must give feedback after
executing an instruction and the output
data is written to the memory.

14. Random-Access Memory (RAM)
• RAM devices are used in computer systems as the main memory. RAM is
considered volatile memory, which means that the stored information is lost
when there is no power. So, RAM is used by the central processing unit (CPU)
when a computer is running to store information that it needs to be used very
quickly, but it does not store any information permanently.
•RAM that runs at 1600 MHz, this clock
will run at 800 MHz, and the data will be
transferred at both posedge and negedge
(hence DDR: double data rate, two bits per
clock cycle). So it's fairly straightforward,
higher memory frequency means higher
data bandwidth, and hence a faster system
•DRAM (Dynamic Random Access
Memory)
• SRAM (Static Random Access Memory)

15. Hard disk drive
• A hard disk drive (sometimes abbreviated as hard drive, HD, or HDD) is a
non-volatile memory hardware device that permanently stores and retrieves
data on a computer.A hard drive is a secondary storage device that consists of
one or more platters to which data is written using a magnetic head, all inside
of an air-sealed casing. Internal hard disks reside in a drive bay, connect to the
motherboard using an ATA, SCSI, or SATA cable,
are powered by a connection to the PSU.
•RPM stands for "revolutions per minute". A
standard hard drive has a spinning disc inside
of it - RPM measures how many times that
disc spins in a minute. As RPM increases, the
speed of your hard drive also increases. So a
hard drive with a higher RPM represents a
faster hard drive
•5400 and 7200 will deliver data about 33%
faster

16. Optical Drive
• An optical drive is a type of computer disk drive that reads and writes data
from optical disks through laser beaming technology.
• This type of drive allows a user to retrieve, edit and delete the content from
optical disks such as CDs, DVDs and Blu-ray disks. Optical drives are among
the most common computer components
•Optical drives work by rotating the inserted
disk at a constant speed, calculated in
revolutions per minute (RPM), which
generally range from 1,600- 4,000 RPM,
where speeds provide faster data reading
time
•Optical drives mainly use an Advanced
Technology Attachment (ATA) bus or a Serial
ATA bus, along with Small Computer System
Interface (SCSI) to send and receive data
from the computer.

17. difference between Ram and a processor?
RAM
• Measured in size, type and
access speed (e.g. (16GB DDR 3
@ 1866 MHz) )
• Acts as a storage for
information
• Handles opened programs
(Good for multi-tasking)
• Less expensive
PROCESSOR
• Measured in clock speed, cores, and
cache (Quad-core processor @ 4.0 GHz,
with 8M cache 4)
• Acts as the brain of the system
• Opens programs (Faster execution of
programs)
• More expensive
• Three Major Operations of a Processor
• Fetch, Decode, Execute
