2. In computing, a keyboard is a typewriter-stylekeyboard, which uses an arrangement of buttonsor keys, to act as mechanical levers or electronic switches.Following the decline of punch cards and papertape, interaction via teleprinter-style keyboards becamethe main input device for computers. Despite thedevelopment of alternative input devices, such asthe mouse, touch screen, pen devices, characterrecognition and voice recognition, the keyboard remainsthe most commonly used and most versatile device usedfor direct (human) input into computers. 3. First we used the cutter to cut the size of a keyboard fromthe thermocol. Then we wrapped the thermocol with chart paper and itbecame the base of our keyboard. Then for making keys of the keyboard we used thermocoland cut the size of the keys. Then we wrapped them with the white paper. After that we pasted the keys to the base of the keyboardand wrote the numbers and drew the symbols. In this way our Keyboard was ready. 4. Base of keyboard Completed keyboard 5. A computer mouse is used to tell a computer what to do, includingmoving the cursor and choosing things on the screen. It got its namebecause the wire coming out of the end of the first computer micereminded people of the tail of a real mouse. Many mice todayare wireless and use batteries. When Silicon Valley was beingreclaimed in California, Douglas Engelbart, a researcher of Stanfordinstitute, wanted to find a way to make using computers easier. Inthose days, using a computer was very hard because they were largemachines. After studying and designing for a long time, Engelbartsucceeded in inventing an input device which he named XY index.At first, it needed two hands to use, but it was changed so that onlyone hand was needed to use it. This is the mouse that we use today. 6. First we cut the base of the mouse from the thermocol. Then we cut a thermocol piece and curved it. We pasted it on the base. Then we wrapped the mouse. In this way our mouse was complete. 7. The central processing unit (CPU, occasionally central processor unit) is thehardware within a computer system which carries out the instructions ofa computer program by performing the basic arithmetical, logical,and input/output operations of the system. The CPU plays a role somewhatanalogous to the brain in the computer. The term has been in use in the computerindustry at least since the early 1960s. The form, design, and implementation ofCPUs have changed dramatically since the earliest examples, but theirfundamental operation remains much the same. On large machines, CPUs requireone or more printed circuit boards. On personal computers and smallworkstations, the CPU is housed in a single silicon chip called a microprocessor.Since the 1970s the microprocessor class of CPUs has almost completely overtakenall other CPU implementations. Modern CPUs are large scale integrated circuits inpackages typically less than four centimeters square, with hundreds of connectingpins. 8. First we cut the different parts of CPU and wrapped them Then we joined the parts. After that we cut the inside parts of the CPU and pasted the inside it. In this way our CPU was ready. 9. A monitor or display (also called screen or visual display unit) isan electronic visual display for computers. The monitor comprisesthe display device, circuitry, and an enclosure. The display device inmodern monitors is typically a thin film transistor liquid crystaldisplay (TFT-LCD) thin panel, while older monitors use a cathoderay tube about as deep as the screen size.Originally, computer monitors were used for dataprocessing while television receivers were used for entertainment.From the 1980s onwards, computers (and their monitors) have beenused for both data processing and entertainment, while televisionshave implemented some computer functionality. Thecommon aspect ratio of televisions, and then computer monitors,has also changed from 4:3 to 16:9 (and 16:10). 10. First we made the different parts of the monitor wrapped them. Then we joined the different parts of the monitor. We made the holder of the monitor afterwards and joined it to the monitor. In this way our monitor was complete.
