Why are transistors important in computers?

Transistors make excellent electronic switches. They can turn currents on and off billions of times per second. Digital computers use transistors as a basic mechanism for storing and moving data.

How does a transistor work in a computer?

A transistor works when the electrons and the holes start moving across the two junctions between the n-type and p-type silicon. By turning a small input current into a large output current, the transistor acts like an amplifier. But it also acts like a switch at the same time.

What is the computer transistor designed to do?

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. Transistors are one of the basic building blocks of modern electronics. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.

Why is the transistor so important?

The transistor went on to replace bulky vacuum tubes and mechanical relays. The invention revolutionized the world of electronics and became the basic building block upon which all modern computer technology rests.

Why transistors are used?

Transistors are a three terminal semiconductor device used to regulate current, or to amplify an input signal into a greater output signal. Transistors are also used to switch electronic signals. The circulation of electrical current through all types of transistors is adjusted by electron addition.

What is the use of micro transistor in the computer?

The transistor is the primary building block of all microchips, including your CPU (central processing unit). It is what creates the binary 0’s and 1’s (bits) your computer uses to communicate and deal with Boolean logic.

What is transistor and how it works?

A transistor is an electronic component that is used in circuits to either amplify or switch electrical signals or power, allowing it to be used in a wide array of electronic devices. A transistor consists of two PN diodes connected back to back. It has three terminals namely emitter, base and collector.

What are the two main functions of a transistor?

Transistor Function So the two functions provided by transistors are switching of electronic signals and amplifying electronic signals.

How does transistor amplify?

A transistor acts as an amplifier by raising the strength of a weak signal. The DC bias voltage applied to the emitter base junction, makes it remain in forward biased condition. Thus a small input voltage results in a large output voltage, which shows that the transistor works as an amplifier.

How did transistors affect the development of computers?

Transistors transformed the world of electronics and had a huge impact on computer design. Transistors made of semiconductors replaced tubes in the construction of computers. By replacing bulky and unreliable vacuum tubes with transistors, computers could now perform the same functions, using less power and space.

What kind of circuit was there before transistors?

Before transistors, digital circuits were composed of vacuum tubes. The story of ENIAC computer speaks volumes about the disadvantages of vacuum tubes in computers.

How do the transistors in a memory chip work?

This is essentially how all computer chips work. For example, a memory chip contains hundreds of millions or even billions of transistors, each of which can be switched on or off individually. Since each transistor can be in two distinct states, it can store two different numbers, zero and one.

Why did they replace vacuum tubes with transistors?

By replacing bulky and unreliable vacuum tubes with transistors, computers could now perform the same functions, using less power and space. Before transistors, digital circuits were composed of vacuum tubes. The story of ENIAC computer speaks volumes about the disadvantages of vacuum tubes in computers.
