- Logical computational thinking
- 1.1.2 Information input, process and output
- Input: is when you enter data in the computer and then its processed and saved turning
it into information useful for the computer
- Processing: in this part all the information that the computer received trough the inputs
are transformed into a digital dialog that is what the computers understand
transforming it into binary system that are 0 and 1
- Only some things can be processed through binary thats is when it comes the ASCII
it process all the data that binary can't like upper lower case letter and,
punctuation
- Also it exists unicode that is used to process alphabets in strange
languages like Chinese, Korean, and Japanese etc..
- Output: when the information is processed then it can be sent
through an output device such as an screen, speakers or a printer

- 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
