What can I find inside my PC case?
The term CPU, central processing unit, refers to the processor or microchip that you
have in your PC. However, this term has also been used to refer to the PC case, tower, or
cabinet and all of the devices that you can find in its interior. In this article we will describe
the most common elements found in the interior of any CPU.
The motherboard or mainboard is the device on which the various
devices found within the PC are mounted upon. Its functions
include, anchoring the different devices, communication and
connection to external peripherals such as a keyboard, mouse or
All the circuits and connectors that we find on the motherboard is what we call the chipset.
Some motherboard models feature integrated graphics or sound chips. On these models
you can choose to not add additional graphics or sound cards if the integrated ones are
sufficient for your requirements. For example, in office PC’s where graphic requirements
are lower will allow you to save some money by not needing to buy an additional graphics
It is very important when choosing a motherboard to know the maximum amount of RAM
you can add to it, the number and types of external connections that it has, and which
processors are supported.
The memory system of a PC operates in a hierarchical manner. At
the far end lies the hard drive. On this device, programs and data
are stored and waiting for when the processor will use them, even
when the computer isn’t on. However, hard drives are too slow for
continuous access. This is why RAM exists. In this memory,
programs and data are stored while they are being executed or
accessed, but when you turn off the PC this memory is erased,
and therefore cannot be used for storing information permanently.
This memory is thousands of times faster than any hard drive, but
also of lower retention capacity.
The RAM memory must be compatible with your motherboard and processor. These
components incorporate a memory controller that defines the type and maximum speed of
the RAM modules that can be used with them.
This is the brain of the system. It reads the instructions and data that
make up programs and files, and executes them accordingly.
Therefore, its importance for performance is crucial. If it’s slow, it will
drag down the entire PC, delivering an unsmooth performance. The
processor not only works with programs and files, but also with all input
generated via peripherals such as a mouse or keyboard.
When choosing a processor you determine the types of motherboards that are compatible
with it, or vice versa in the case of choosing a motherboard first. For instance an Intel
processor won’t function with an AMD chipset motherboard.
The architecture (x86 or x64), the number of cores, the cache, the functioning frequency,
and power consumption are features that distinguish processors one from another.
The graphics card aids the processor in carrying out graphic
rendering operations that appear on your PC monitor. As
mentioned earlier, sometimes the functionality of a graphics
card is already integrated onto the motherboard and therefore
an additional device is unnecessary.
Any modern graphics card is capable of performing a large number of tasks. Among them
are the creation and rendering of three dimensional worlds that you see in modern video
games or playing high definition video.
This is a device that has transitioned from being separate to being integrated onto the
motherboard and now finally integrated into the processor. Soon it will be a rarity to see a
PC without an integrated graphics card or chip.
Its function is obvious and it has efficiently carried it out since the
very first PC’s appeared. It’s in charge of storing data when the
computer isn’t powered. Therefore its primary features are transfer
speeds and storage capacity.
Unless you work intensely with video processing, the transfer speed
of a hard drive isn’t that important.
The latest developments in relation to these devices are SSD hard drives. Because they
don’t have moving parts, and are composed of solid state memory. They are much faster
and also free from some of the inconveniences that normal hard drives present such as
noise, fragile endurance to impacts (such as dropping them, or hitting them by accident).
Their only downside is their significantly higher cost.
