WARNING!
HARDWARE GROUPS
1. Feed data = inserire i dati(nel computer)
2. CPU = Central Processing Unit = Processore
3. Keep = conserva, mantiene

4. Consisting of = composto da
FUNCTIONING
5. Interlinked = interconnessi
6. The faster the CPU works, the more powerful the computer is = Più velocemente la CPU lavora(funziona),più potente sarà il computer
The computer system
Hardware groups
There are four important groups that we can distinguish in a computer system:
4 Storing. After processing,this part functions as a memory which keep* data for the future use
3 Output. The equipment which displays the results of the computer's work (Like printer or screen)
2 Processing. The equipment that,with the help of CPU* ,follows the instruction and transform the data in a result
1 Input. The equipment needed to feed data* into the computer
Functioning
All the pieces are interlinked* through a communication network called "bus" where the centre is the motherboard that is controlled by CPU.
The CPU is the most important element of a computer's hardware,it processes the data and in the same time controls the operation of all the other pieces of hardware
The faster the CPU works, the more powerful the computer is*. The speed of CPU is called "clock speed" measured in hertz,where each cycle represents one operation.
Operations
A computer is a complex device consisting of* many
different components.For its functioning it can be divided into four groups:
4.Store the results in its memory
3.Show results of the processing
2.Process data according to the instructions
1.Take in data
