- 8. COMPUTER | TRANSISTORS q transistor is the basic computing unit of a computer
- 9. COMPUTER | TRANSISTORS q a transistor has 2 (binary) states: on and off q 1 bit is represented by 1 transistor q 8 bits (1 byte) are represented by 8 transistors
- 10. COMPUTER | TRANSISTORS q thousands/millions of tiny transistors are then embedded in microchips/integrated circuits (along with resistors and capacitors)

- 20. COMPUTER PROGRAMMING The processof designing, writing, testing, debugging, and maintaining the source code of computer programs. This source code is written in one or more programming languages (such as Java, C++, C#, Python, etc.)
- 21. COMPUTER PROGRAMMING The purposeis to create a set of instructions that computers use to perform specific operations or to exhibit desired behaviors. Requires expertise in many different subjects, including knowledge of the application domain, specialized algorithms and formal logic.
- 22. COMPUTER PROGRAMMING Application programmerswrite programs to handle a specific job, such as a program to track inventory within an organization. They also may revise existing packaged software or customize generic applications which are frequently purchased from independent software vendors.
- 23. COMPUTER PROGRAMMING Systems programmerswrite programs to maintain and control computer systems software, such as operating systems and database management systems. These workers make changes in the instructions that determine how the network, workstations, and CPU of the system handle the various jobs they have been given and how they communicate with peripheral equipment such as printers and disk drives.

- 60. PYTHON | ENDNOTES q Python is readable, maintainable, beautiful, and elegant. q There are many reusable Python libraries out there. q Not all things are important: q you don’t have to study all the intricacies of a programming language to be productive. q EQ is very important in programming in general: q patience/persistence (never say die attitude) q attention to details (spotting anomalies to the lowest level) q belief/positive thinking (having confidence and an upbeat attitude) q resourcefulness/creativity (combining basic language constructs) q determination (especially when debugging)
