   • Logical computational thinking
     • Andres Gutierrez A01066333
       • Sandra Miranda Leal

2. 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

           • Output: when the information is processed then it can be sent through an output device such as an screen, speakers or a printer

3. 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
