What is the function of microprocessor?
The microprocessor is the central unit of a computer system that performs arithmetic and logic operations, which generally include adding, subtracting, transferring numbers from one area to another, and comparing two numbers. It’s often known simply as a processor, a central processing unit, or as a logic chip.
What is the function of a transistor in a microprocessor?
Without re-writing the book on digital logic and Computer Organization and Design, a transistor implements the function of a switch in the context of microprocessors. They are used to create “switching circuits” typically (e.g. CMOS logic gates).
How is a transistor similar to a switch?
Basically, a transistor is a switch (between two of the pins: the collector and the emitter ) that is operated by having a small current in the third pin called the base. Use the checkboxes below this transistor to understand how applying a voltage to the base of a transistor is equivalent to turning on a switch.
What makes up the base of a transistor?
A transistor is an electronic component with three pins. Basically, a transistor is a switch (between two of the pins: the collector and the emitter ) that is operated by having a small current in the third pin called the base.
What are the functions of a microprocessor in a computer?
The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer’s central processing unit. The integrated circuit is capable of interpreting and executing program instructions and performing arithmetic operations.
