Atomic number of silicon is 14. So the electronic configuration is 2,8,4. So there are 4 electrons in outermost orbit. So to complete the octet, it has to get 4 electrons causing much electro negativity or to give 4 electrons causing much electro positivity. So it is reluctant to give electrons unless larger force is applied. So for the same reason carbon and germanium having 4 electrons in outer orbit are semiconductors of electricity. So when we add trivalent impurity (like aluminium ) to silicon it promote electrical conductivity and if we add pentavalent impurity ( like phosphorus) we get flow of electricity from trivalent plus silicon to pentavalent plus silicon. This is the basic principle used in electronics.

True or false the first computers to use the integrated circuit were known as third-generation computers?
True. Some of these computers used hybrid integrated circuits (e.g. IBM System/360) and some used monolithic integrated circuits (e.g. Apollo Guidance Computer, Minuteman II Guidance Computer)
Where are printed circuit boards used?
Flexible printed circuits are used so that boards can be conformed to a particular shape. They are often used in computer keyboards, cameras, calculators, and cellular phones.
What holds all the circuits together in a computer?
The circuits in a computer are held together primarily by the motherboard, which serves as the main printed circuit board (PCB) connecting various components such as the CPU, memory, and expansion cards. The motherboard provides pathways for electrical signals and power to flow between these components. Additionally, solder and connectors are used to secure the circuits, ensuring stability and functionality. Together, these elements create a cohesive system that allows the computer to operate efficiently.
What are electronic and mechanical equipment called?
Digital circuits are the most common physical representation of Boolean algebra and are the basis of all digital computers. Computer's industrial processes are constructed of digital circuits.
What 2 elements are used in computer circuits?
they are co md
Where is germanium and silicon located in computer chips?
Germanium is not used in integrated circuits. Silicon is.
What energy trans formations are in a computer?
Electronic circuits, such as the one used in a computer, use electric energy. As it is used up, such energy is converted into heat energy.
What are series circuits used in?
Christmas tree lights and computer cables are also connected in series.
What elements were used to process data in each of the four generations of computers?
The first generation used vacuum tubes, the second used transistors, the third used integrated circuits, and the fourth used integrated circuits on a single computer chip.
What materials were used to build the space station?
Silcon Carbide and other stuff like that
What are most of the circuits located in your house?
Most of the circuits are contained within your computer.
Why is a computer chip called a chip?
Computer chips are built on a slice of silicon. Silicon forms the basis of transistors which make up a complete circuit. The circuit is photo etched onto the silcon forming complex circuits containg transistors, resistors, capacitors and diodes. The silicon is grown as a single crystal. The crystal is then sliced into thin wafers, onto which the circuit is etched. These resemble a sliced potato or CHIP.
Which computer generation used transistor in it?
The Second Generation Computer used transistors
What is the use of computer boards?
A computer circuit board is used to connect the electronic components and circuits inside of a computer. Computer circuit boards are composed of laminates, copper clad laminates, and copper foil.
Silicon is used in computer circuits what special of silicon means that it can be used for this?
It is a semiconductor and therefore can be used to make diodes and transistors for digital circuits which are robust mechanically and electrically. Silicon is inexpensive and widely available, and there is now a well developed industry in handling and manipulating it.
Was the first computer made of electrical circuits?
The first electronic digital computer was.
