They follow instruccions from the user and from the computer programmer.
Aplications (word processors, video games, etc) are set of instructions]]> 2018-02-19 15:07:31 UTC https://padlet.com/martin_sara1/w0gmr2k8oiaw/wish/232946808 martin_sara1 https://padlet.com/martin_sara1/w0gmr2k8oiaw/wish/232949614 Is the part of the computer that we can touch
The hardware is the components that are interconnected. The computer needs all those components, but the are independent and we can change any of them.
The basic components are the CPU, the memory, the graphics card and the peripherals.]]> 2018-02-19 15:14:28 UTC https://padlet.com/martin_sara1/w0gmr2k8oiaw/wish/232949614 martin_sara1 https://padlet.com/martin_sara1/w0gmr2k8oiaw/wish/232951705 The CPU (Central Processing Unit) is a big green, plastic board with a lot of chips and many other alectronic components mounted on it.
The central processing unit is also called "the processor". It is the "brain" of the computer; it looks at the information and takes decisions based on logic]]> 2018-02-19 15:19:28 UTC https://padlet.com/martin_sara1/w0gmr2k8oiaw/wish/232951705 martin_sara1 https://padlet.com/martin_sara1/w0gmr2k8oiaw/wish/232953873 Memory stores information.

Thee Os defines the internal logic for the functioning of the computer.
To program the OS, we must know which are the components of the hardware and how they are connected.
-When we switch off the computer, the OS decides to first close the applications, then to transfer al data from the RAM to the HD, and finally to switch itself off]]> 2018-02-20 08:43:30 UTC https://padlet.com/martin_sara1/w0gmr2k8oiaw/wish/233163056 martin_sara1 https://padlet.com/martin_sara1/w0gmr2k8oiaw/wish/233164356 It is stored in the hard disc (the aplications)
