Study Notes
- Transistor is a semiconductor device for amplifying, controlling, and generating electrical signals.
- It was invented at Bell Laboratories in 1947 and the first commercially successful transistor was produced by Texas Instruments in 1954.
- Integrated circuits (IC) are a set of electronic components on a single unit, also called a chip or microchip.
- Microprocessors are computer processors that implement the functions of a CPU on a single IC.
- Moore's Law states that the number of transistors in a dense integrated circuit has doubled approximately every two years.
- A computer system has three basic components: input unit, CPU, and output unit.
- The CPU is responsible for processing data and commands according to instructions provided.
- The Von Neumann architecture is the design upon which many general-purpose computers are based.
- The key elements of Von Neumann architecture are the control unit, arithmetic and logic unit (ALU), and memory unit.
- The control unit is responsible for coordinating tasks between all components of a computer system.
