2. COMPUTER HARDWERE
Computer hardware refers to the physical components that make up a
computer system.
There are many different kinds of hardware that can
be installed inside, and connected to the outside, of a
computer.

Take a tour inside of your desktop PC to learn how all the hardware in a traditional
desktop PC connects together to create a complete computer system like the one you
may be using right now.

3. KEYBOARD
It is the most important input device of a computer. It is
designed to allow you input text, characters, and other
commands into a computer, desktop, tablet, etc. It
comes with different sets of keys to enter numbers,
characters, and perform various other functions like
copy, paste, delete, enter, etc.

4. MOTHERBOARD
Alternatively called the mb, mainboard, mboard, mobo, mobd, backplane
board, base board, main circuit board, planar board, system board, or a logic
board on Apple computers. The motherboard is a printed circuit board and
foundation of a computer that is the biggest board in a computer chassis. It
allocates power and allows communication to and between the CPU, RAM, and
all other computer hardware components.

5. MOUSE
A computer mouse is a handheld hardware input device that controls
a cursor in a GUI (graphical user interface) for pointing, moving and
selecting text, icons, files, and folders on your computer. In addition
to these functions, a mouse can also be used to drag-and-drop objects
and give you access to the right-click menu.

6. WEBCAM
A webcam is a video camera which is designed to record or stream to
a computer or computer network. They are primarily used in
videotelephony, livestreaming and social media, and security.
Webcams can be built-in computer hardware or peripheral devices,
and are commonly connected to a device using USB or wireless

7. VIDEO PROJECTOR
A video projector is an image projector that receives a video signal and projects
the corresponding image on a projection screen using a lens system. Video
projectors use a very bright ultra-high-performance lamp (a special mercury arc
lamp), Xenon arc lamp, LED or solid state blue, RB, RGB or remote fiber optic
RGB lasers to provide the illumination required to project the image, and most
modern ones can correct any curves, blurriness, and other inconsistencies
through manual settings. If a blue laser is used, a phosphor wheel is used to turn
blue light into white light, which is also the case with white LEDs. (White LEDs
do not use lasers.) A wheel is used in order to prolong the lifespan of the
phosphor, as it is degraded by the heat generated by the laser diode. Remote
fiber optic RGB laser racks can be placed far away from the projector, and
several racks can be housed in a single, central room. Each projector can use up
to two racks, and several monochrome lasers are mounted on each rack, the
light of which is mixed and transmitted to the projector booth using optical

8. USB FLASH DRIVE
A USB flash drive is a data storage device that includes flash memory
with an integrated USB interface. It is typically removable,
rewritable and much smaller than an optical disc. Most weigh less
than 30 g. Since first appearing on the market in late 2000, as with
virtually all other computer memory devices, storage capacities have
risen while prices have dropped. As of March 2016, flash drives with
anywhere from 8 to 256 gigabytes were frequently sold, while 512 GB
and 1 terabyte units were less frequent. As of 2018, 2 TB flash drives
were the largest available in terms of storage capacity. Some allow

9. GRAPHICS CARD
A graphics card is a computer expansion card that
generates a feed of graphics output to a display device
such as a monitor. Graphics cards are sometimes called
discrete or dedicated graphics cards to emphasize their
distinction to integrated graphics processor on the
motherboard or the CPU. A graphics processing unit that
