How computers Work logic gates?

When a transistor is on, or open, then an electric current can flow through. And when it’s off, then no current flows. When you string a bunch of these transistors together, then you get what’s called a logic gate, which lets you add, subtract, multiply, and divide binary numbers in any way imaginable.

How do electrons make computers work?

An electronic computer computes by moving electrons around, so the physical restrictions of an electron moving through matter determine how fast such computers can run. It is important to realize, however, that information can move about a computer much faster than the electrons themselves.

How does electricity flow through a computer?

When you first press the power button, the computer sends a signal to the computer power supply, which converts the AC (alternating current) to DC (direct current). This power supplies the computer and its components with the proper amount of voltage and electricity.

How does and logic gate work?

An AND gate is a logic gate having two or more inputs and a single output. An AND gate operates on logical multiplication rules. In this gate, if either of the inputs is low (0), then the output is also low. If all of the inputs are high (1), then the output will also be high.

How do computers process the data and complete the tasks?

A computer uses a Central Processing Unit or CPU to do all its decision-making and data processing. The CPU has an internal set of instructions it follows when it receives a command. Programmers use different languages to give the CPU commands. These languages are more human readable than the CPU’s machine language.

How are computers getting faster?

Fundamentally, computers are getting faster because every new generation uses a better technology for transistors, the fundamental building block. This plot shows the trend of the number of transistors used on a CPU chip versus time.

How does a computer turn electrical signals into binary data?

Computers use binary – the digits 0 and 1 – to store data. The circuits in a computer’s processor are made up of billions of transistors . A transistor is a tiny switch that is activated by the electronic signals it receives. The digits 1 and 0 used in binary reflect the on and off states of a transistor.

How is a logic gate made?

“A logic gate in a microchip is made up of a specific arrangement of transistors. For modern microchips, the transistors are of the kind called Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET), and the semiconductor used is silicon. “In a logic-gate arrangement, each of the MOSFETs works like a switch.
