A transistor is a semiconductor device that transfers a weak signal from low resistance circuit to high resistance circuit. In simple words, what it means is that it regulates and amplifies electrical signals such as voltage or current.
Transistors are special because they allow you to control how much current flows through a circuit. This can be achieved by controlling the voltage across two of the transistor leads. Each transistor has three leads.
A transistor is an influential little invention that changed the course of history for computers and all electronics. A transistor consists of two PN diodes that are connected back to back. It has three terminals that are named emitter, base and collector. John Bardeen, William Shockley, and Walter Brattain were scientists at the Bell Telephone Laboratories. The idea for transistors arose when they were working on an idea that used a field effect to control the current in a semiconductor.

Variables and data types in python as the name suggests are the values that vary. In a programming language, a variable is a memory location where you store a value. The value that you have stored may change in the future according to the specifications.

The functional components of a computer can be categorized as follows:
- Input Devices (All those devices using which instructions/information is fed into the computer) Ex. Keyboard, Mouse, Scanner, Joystick, touchpad, trackball etc.
- Output Device (All those devices through which processed information is presented to the user ) Ex. monitor, printer, speakers etc
- Memory and Storage Device: Its again of two types RAM and ROM. For easier understanding sake, RAM is the one with short term memory loss syndrome. Which means RAM only stores things for a short while, whereas ROM is the one with permanent storage capacity. RAM helps process the data faster and then store it in ROM for future use.
- CPU: CPU is simply put the brain. Its a combination of various chips and circuit boards that help process data and convert it into machine readable format and back.

The main difference between batch processing and multiprogramming is that batch processing allows multiple programs to execute with minimum human interactions while multiprogramming allows multiple programs to execute on a single processor system. Multi-Programmed Batch System: In multiprogramming, multiple programs (or jobs) of different users can be executed simultaneously (i.e. at the same time). The multiple jobs that have to be run simultaneously must be kept in main memory and the operating system must manage them properly. Batch systems can work offline so it makes less stress on processor. Processor consumes good time while processing that mean it knows which job to process next. In real time systems we don't have expectation time of how long the job is and what is estimated time to complete it.
