By MUHAMMAD TAUFIK,S.T.,M.T.

2. Digital forensics (sometimes known as digital
forensic science) is a branch of forensic
science encompassing the recovery, investigation,
examination and analysis of material found in digital
devices, often in relation to mobile devices
and computer crime. The term digital forensics was
originally used as a synonym for computer
forensics but has expanded to cover investigation of
all devices capable of storing digital data

3. COMPUTER AND ITS
COMPONENT
 By MUHAMMAD TAUFIK,S.T.,M.T.

4. DESKTOP COMPUTER
LAPTOP COMPUTER VS
Cost
Desktop - There is a wide variety of component options available for desktops,
allowing for a large range of prices, but the starting point is relatively cheap.
Desktops can start as low as $600 and still be a pretty powerful system.
Laptop - Laptops can have a fairly wide variety of component options, but they are
more limited than desktops. To get a more powerful laptop (higher speed, better
graphics, more storage space, etc.), the price can be considerably higher, ranging
up to $1000 or more, depending on the brand.
Bottom line: Desktop wins this category. A desktop computer is always cheaper
than a laptop.

5. DESKTOP COMPUTER
LAPTOP COMPUTER VS
Portability
Desktop - Desktops are large and have a separate monitor. While it's possible to
take a desktop from place to place, it's cumbersome and not the choice for
portability. They are designed to be used in a single location and not moved around
much, if at all.
Laptop - Laptops are very portable due to their compact size. They were designed
to be taken from place to place, carried in a backpack or laptop carrying case. They
are great for on-the-go use.
Bottom line: Laptop wins this category. If you need portability, the laptop is the
answer.

6. DESKTOP COMPUTER
LAPTOP COMPUTER VS
Internal storage
Desktop - Desktop computers may have multiple internal storage drives installed.
Laptop - Laptop computers usually have room for only one internal drive. If more
internal storage is required, the drive must be completely replaced, or storage or a
must be used.
Bottom line: Desktops win this category. Although both computers can
have external drives connected or use cloud storage, desktop computers can have
several internal hard drives and other drives in them.

7. DESKTOP COMPUTER
LAPTOP COMPUTER VS
Processor
Desktop - Desktop processors are larger, but this also means the desktop
processors can be more powerful than laptop processors. New, advanced
processors on the market are often available in desktop computers first.
Laptop - Laptop processors have nearly caught up to desktop processors but are
still limited compared to desktop processors. Gaming laptops can have equal
performance but have a much higher price.
Bottom line: Desktops win this category. Because desktops don't need to worry
about conserving battery life, they'll always have better processors.

8. DESKTOP COMPUTER
LAPTOP COMPUTER VS
Assembly and set up
Desktop - Setting up a desktop takes a bit of extra work to hook everything up,
start it up, and begin to use. It also requires more space to set up. While it's not
difficult to connect everything together, it is still more cumbersome than a laptop.
Laptop - Laptops are built to be easy to use, requiring little time to get running.
Take it out of the box, plug it in, and press the power button. Within minutes, the
laptop is ready to use.
Bottom line: Laptops win this category. A laptop can be up and running within a
few minutes.

9. Computer Parts
 There are many
parts that work
together to make a
computer work.

10. Hardware
 Physical parts of the
computer, including
processor and
memory chips,
input/output
devices, tapes,
disks, modems,
cable, etc.

11. CPU
 The Central
Processing Unit

12. Processor
 The CPU – The chip
or chips that
interpret and
execute program
instructions and
manage the
functions of input,
output, and storage
devices.

13. MOTHERBOARD
is the main printed circuit board (PCB) in general-
purpose computers and other expandable systems.
It holds and allows communication between many
of the crucial electronic components of a system,
such as the central processing unit (CPU)
and memory, and provides connectors for
other peripherals. Unlike a backplane, a
motherboard usually contains significant sub-
systems, such as the central processor,
the chipset's input/output and memory
controllers, interface connectors, and other

15. Computer Case
 Contains the major
components of the
computer. It helps
protect them.

19. POWER SUPPLY UNIT (PSU)
A power supply unit (PSU) converts mains AC to low-
voltage regulated DC power for the internal components
of a computer. Modern personal computers universally
use switched-mode power supplies. Some power
supplies have a manual switch for selecting input
voltage, while others automatically adapt to the mains
voltage.

20. POWER SUPPLY UNIT (PSU)

21. POWER SUPPLY UNIT (PSU)

22. Monitor
 A display screen to
provide “output” to
the user. It is where
you view the
information your are
working on.

23. Video Card
GRAPHIC PROCESSING UNIT(GPU)
 Connects the computer
to the monitor. It is a
circuit board attached
to the motherboard that
contains Graphic
processor, the memory
and other circuits that
necessary to send
information to the
monitor for display on
screen.

24. Vga evolution
Video Graphics Array (VGA) is a video display controller and accompanying de
facto graphics standard, first introduced with the IBM PS/2 line of computers in 1987.
IBM intended to supersede VGA with the Extended Graphics Array (XGA) standard,
but failed. Instead, VGA was adapted into many extended forms by third parties,
collectively known as Super VGA, then gave way to custom graphics processing
units which, in addition to their proprietary interfaces and capabilities, continue to
implement common VGA graphics modes and interfaces to the present day
Unlike the graphics adapters that preceded it (MDA, CGA, EGA and many third-party options)
there was initially no discrete VGA card released by IBM. The first commercial implementation
of VGA was a built-in component of the IBM PS/2, in which it was accompanied by 256KB of
video RAM, and a new DE-15 connector replacing the DE-9 used by previous graphics
adapters.
IBM later released the standalone IBM PS/2 Display Adapter, which utilized the VGA but could
be added to machines that did not have it built in.
The VGA was a single chip implementing the entirety of a video display controller, rather than
the many discrete components and ICs of the graphics adapters that had preceded it. The
term "array" rather than "adapter" in the name denoted that it was not a complete
independent expansion device, but a single component that could be integrated into a
system.
The VGA required only video memory, timing crystals and an external RAMDAC, and its small
part count allowed IBM to include it directly on the PS/2 motherboard, in contrast to prior IBM
PC models – PC, PC/XT, and PC AT – which required a separate display adapter installed in a
slot in order to connect a monitor.
