1.1.3 Internal functioning of a computer
The system unit is the main part and is composed of
microprocessors, memory and support circuits
The microprocessor is the most important part because its
the one that controls everything and makes a computer work
it is calles CPU
The CPU is divided in two the control unit and the arithmetic logic unit
The control unit decides were to send the signals and where information
belongs in the computer
The arithmetic logic unit is the one in charge of all the mathematical
and logical things of the computer
The cache is a very important part of the perforamance of the computer
because it process the information and is between the microprocessor
and the RAM
The cache provides faster data that its not so complicated or that os
frequently used
The flash memory is another very important part because its a writing and reading
memory that its used when the devices are not on so it docent forget some things
and tasks
Other main devices that are need for the use of a computer like a mouse,
keyboard etc.. are connected trough the ports of the computers and it exist many
types like, serial, USB and HDMI
The main advantage of the USB its that it recognizes almost instantly what
device is connected without needing to reboot
Expansion cards are main part of the computer that are installed during the assembly of a computer and it enables access to many things and
have the ports were the inputs can be connected, one of the main uses of a expansion card is to get internet , process graphics, audio and
bluetooth
