This is my new (1) computer that sits on top of a table or desk (I've also got a (2) small computer which can be carried or placed on your knees) . As you can see, there are six main (3) parts to it. The first is the (4) part of the computer that runs it and controls what it does, and this is the most important bit. It carries the (5) part that stores and controls the flow of information , including the (6) round thing that is used for storing information . Mine has a particularly high (7) capacity for storing information , which means that it's much faster than most. It came with its own (8) computer programs package (including (9) writing, checking and changing texts , (10) calculating in columns of figures , and (11) producing texts and pictures for magazines packages). You can also (12) put in other programs using the (13) sliding tray for carrying round, plastic, information-holding things , or the (14) hole for connecting computer parts to one another (into which you can put a (15) small plastic and metal stick which can hold a lot of information ). The other five parts of the computer are the (16) screen that lets you see what your computer is doing, the (17) flat thing with the letters and numbers on it that let you control the computer , the (18) machine that lets you make copies of the documents that you create on your computer , the (19) device for making color copies of photographs and other documents which you can put onto your computer , and last but not least, the (20) device that you hold in your hand and move across your desk to control the cursor .
