inside of a typical desktop computer.
In this demo, we will be examining components of a typical desktop computer.
A desktop computer is made of many parts referred to typically as hardware.
First, you'll see the exterior of the computer.
This is the case, or also known as a chassis.
Once inside, you'll see the motherboard, which can also be called a main board.
You'll also see Si pues or processors
RAM or memory
the power supply
input devices such as mice and keyboards,
an output devices such as monitors, printers and speakers.
You might also find graphics cards, which are mostly for game enthusiasts, professionals
and for computers with SI pues that cannot perform video calculations on board.
The exterior of the case holds various ports, flaps and buttons.
Let's go over the common ports.
At the top of the case are USB ports
and slots for media card readers
to base for CD. DVD drives are hidden behind these plastic flaps.
De eject buttons are on the side
behind the flap. On the bottom is another USB port,
the microphone in
and headphone out audio ports.
The backside of most computers will have the following major ports.
At the top are more USB ports.
Nearby is a digital audio out port.
To most desktop users, the following is the most important port. The video connector.
This computer has to shown
Devi I digital
VJ Analog in blue.
There's another group of USB ports.
There is a FireWire 400 port
comparable. Tow us be, too,
and on Ethernet port for networking. Usually you need to boot the computer and look in the BIOS or the operating system to determine the speed of the Ethernet port.
Near the bottom is a 5.1 audio cluster.
Light green is typically the color used for front stereo sound. Out.
We're going to build a computer to show you how each of the parts typically fit together, and we will describe what each component does.
The biggest part of a computer is the case.
This is usually made of plastic or metal
and is designed to hold all the internal components of the computer
here, the core components of a computer,
the CPU heat sink with fan attached, which keeps the CPU cool.
The CPU, which does billions of calculations per second man, is considered the brain of the computer.
The thermal paste maximizes the effectiveness of the CPU cooler and is generally considered required
the ram or system memory
and, on bottom, the motherboard.
When placing the CPU in the slot on the motherboard, remember to align the seaview using the visual and physical markers.
Installing the CPU incorrectly can permanently damage the communication pins.
The CPU is now in the slot
time to do the cooling.
Apply thermal pace to the top of the Cebu so the CPU cooler can do its job and pull heat away
while applying the paste. Put enough on there too thinly. Cover the entire surface, but stop just before the edges all the way around.
As the cooler tightens down on top, some of the paste will be pushed to the edges,
and if there is too much, it can leak out and onto the motherboard.
This cooler uses a two point clip, top and bottom too attached to the motherboard.
It might feel like you're squishing the CPU.
However. This process is designed to maximize the thermal transference into the cooler and away from the CPU
difference. Cebu coolers will attach with different brackets, hooks or screws.
The memory will have a notch on the bottom that matches this lot on the motherboard
a line, and see carefully to check if the round fits before pushing down hard
As you push down, the clips on either side will snap into the side. Notches in the ram. Sticks
to ram sticks are installed
now on to putting the motherboard into the case.
With the core items mounted to the motherboard, we insert everything into the case, aligning the ports with the back planes and the holes for the screws underneath.
Once everything is lined up, the screws are inserted and tightened.
Next, installed a CD Rahm drive. To do this, it usually is necessary to remove the front panel.
Newer cases will sometimes come with Tulis bays, which means you do not need screws. Toe hold in the city room. Dr.
Remember to plug in the power and the data cables in the back. If you are installing or replacing the drive
here, you can see the video card is installed, which goes in similar to Ram.
There's only one way it will fit into this lot so carefully a line, and then push down
the power supply and the hard drive have been installed by sliding them in into their appropriate babes and screwing them in similar to the CD room. Dr.
This concludes the look into a typical desktop computer.
