The hardware is the components that are interconnectd.
The basic components are the CPU, the memory, the graphics card and the peripherals.]]> 2018-02-06 08:48:00 UTC https://padlet.com/zubimendi_maialen/x7xd0qujwlis/wish/228476889 zubimendi_maialen https://padlet.com/zubimendi_maialen/x7xd0qujwlis/wish/232947761 The CPU is a big, green, plastic board with a lot of chips and many other electronic components mounted on it.]]> 2018-02-19 15:09:44 UTC https://padlet.com/zubimendi_maialen/x7xd0qujwlis/wish/232947761 zubimendi_maialen https://padlet.com/zubimendi_maialen/x7xd0qujwlis/wish/232949481 Memory stores information.
There are various types of memory in the computer:
FIXED MEMORIES
1. Hard disc: Also called "hard drive" , it is a set of rigid disc whit a magnetic surface.
           - Advantages: It can store a large amount of data (today around 1 TB). We can save and erase  the  information when we  want.
           - Disadvantages: It is relatively slow: compared to other types of memory, it takes longer to read and write information.
2. RAM (Random Access Memory): This is a green plastic card with chips. The RAM is installed in a slot on the mother board.
            - Advantages: It stores (write) and retrieves (reads) quickly.
            - Disadvantages: We lose the work if there is an electrical power cut.
PORTABLE MEMORIES
They are easy to connect and disconnect from the computer.
CDs, DVDs: We call them "optical memories" bacause they use light to work.
            - Advantages: Cheap.
            - Disadvantages: Not good to rewite.
Pen drives, memory cards: They store the information in chips.
            - Advantages: Rewritable. Quick.
            - Disadvantages: More expensive than a CD or a DVD.]]> 2018-02-19 15:14:08 UTC https://padlet.com/zubimendi_maialen/x7xd0qujwlis/wish/232949481 zubimendi_maialen https://padlet.com/zubimendi_maialen/x7xd0qujwlis/wish/235405078 The graphics card looks similar to the RAM.

ENTRY PERIPHERALS
Entry peripherals give information to the computer
EXIT PERIPHERALS
The computer uses the exit peripherals to give information to us or to an actuator]]> 2018-03-05 19:45:43 UTC https://padlet.com/zubimendi_maialen/x7xd0qujwlis/wish/238319011 zubimendi_maialen https://padlet.com/zubimendi_maialen/x7xd0qujwlis/wish/238322398 Software is the part of the computer that we can't touch.]]> 2018-03-05 19:50:46 UTC https://padlet.com/zubimendi_maialen/x7xd0qujwlis/wish/238322398 zubimendi_maialen https://padlet.com/zubimendi_maialen/x7xd0qujwlis/wish/238323522 There is one OS per computer; not more, not less.
