A gadget is simply any innovative idea or mechanically constructed object. Gadgets can be called gizmos too. Almost every country in the world has produced and markets many different kinds of gadgets. Gadgets can be a useful and entertaining part of a person’s life, or they can ruin your life if you are not careful! If you have ever owned a gadget then you will realize that just about everyone wants one.
Almost all electronic gadgets have some component related to a CPU. The most common and influential of all CPU components is the CPU. The CPU is an essential part of the gadget as it controls the functioning of the entire device.
The main function of the CPU is to perform calculations and to store data. A chip having a CPU and an embedded memory or an SD card is termed an embedded system. There are various kinds of embedded systems available in the market and the most popular type is an open-ended appliance such as a digital camera or a pager. The most important function of the CPU is to process instructions from the program code that is executed by the microprocessor. Instructions for the execution of various commands can be accessed directly from the memory if the necessary internal storage is available.
The main input and output devices that come attached with a gadget are known as the monitor and the keyboard. They control the functioning of the CPU by performing specific tasks. The monitor is basically the image display unit of the gadget. The monitor shows the live action through the built in camera. It is an important component of the GADGET which monitors the functions of the processor.
The GADGET also includes a microcontroller which is similar to the computer’s microprocessor. The microcontroller controls all the other components of the GADGET. It controls the generation of signals to and from the computer to the GADGET. A chip known as microfabricator is used to fabricate the chip that controls the overall functioning of the GADGET.
The microfabricated chip and its attached circuits are made of several types of materials such as silicon, plating, etc. Silicon based chips are used to make a logic control system. Silicon based logic control systems are relatively less expensive than other logic control systems and they have high reliability. The logic control chips are very simple and therefore it requires a low amount of programming. Programming is required to control the operation of the GADGET.
