KEYBOARDIn computing, a keyboard is a typewriter-style keyboard, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches. Following the decline of punch cards and paper tape, interaction via teleprinter-style keyboards became the main input device for computers. Despite the development of alternative input devices, such as the mouse, touch screen, pen devices, character recognition and voice recognition, the keyboard remains the most commonly used and most versatile device used for direct (human) input into computers.
First we used the cutter to cut the size of a keyboard from the thermocol.
Then we wrapped the thermocol with chart paper and it became the base of our keyboard.
Then for making keys of the keyboard we used thermocol and 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
keyboard and wrote the numbers and drew the symbols.
In this way our Keyboard was ready.
STEPS USED FOR MAKING MODEL OF
KEYBOARD
MOUSE
A computer mouse is used to tell a computer what to do, including moving the cursor and choosing things on the screen. It got its name because the wire coming out of the end of the first computer mice reminded people of the tail of a real mouse. Many mice today are wireless and use batteries. When Silicon Valley was being reclaimed in California, Douglas Engelbart, a researcher of Stanford institute, wanted to find a way to make using computers easier. In those days, using a computer was very hard because they were large machines. After studying and designing for a long time, Engelbart succeeded in inventing an input device which he named 'XY index'. At first, it needed two hands to use, but it was changed so that only one hand was needed to use it. This is the mouse that we use today.
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.

CPU(CENTRAL PROCESSING UNIT)
The central processing unit (CPU, occasionally central processor unit) is the hardware within a computer system which carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system. The CPU plays a role somewhat analogous to the brain in the computer. The term has been in use in the computer industry at least since the early 1960s. The form, design, and implementation of CPUs have changed dramatically since the earliest examples, but their fundamental operation remains much the same. On large machines, CPUs require one or more printed circuit boards. On personal computers and small workstations, the CPU is housed in a single silicon chip called a microprocessor. Since the 1970s the microprocessor class of CPUs has almost completely overtaken all other CPU implementations. Modern CPUs are large scale integrated circuits in packages typically less than four centimeters square, with hundreds of connecting pins.
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.

MONITORA monitor or display (also called screen or visual display unit) is an electronic visual display for computers. The monitor comprises the display device, circuitry, and an enclosure. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors use a cathode ray tube about as deep as the screen size.Originally, computer monitors were used for data processing while television receivers were used for entertainment. From the 1980s onwards, computers (and their monitors) have been used for both data processing and entertainment, while televisions have implemented some computer functionality. The common aspect ratio of televisions, and then computer monitors, has also changed from 4:3 to 16:9 (and 16:10).
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.
