Computer Science notes
What are some misconceptions about computer science ? - Answer-• All about programming
• Building computer (Engineering) /fixing computer ( IT)
• Using computer applications
Algorithm - Answer-well order collections of unambiguous and effectively computable operations
that when executed produces a result in a finite amount of time
What 5 things must a algorithm be? - Answer-• Well ordered- set in a way that you always know
what to do next
• Unambiguous- one interpretations perfectly clear what instructions mean
• Effectively computable - the computing agent knows how to execute the instructions
• Produces a result-
• Finishes in a finite amount of time- set amount of time, ends does not go on forever
What is the single most important skill for a computer scientist ? - Answer-problem solving
What is problem solving? - Answer-Problem solving means the ability to formulate problems,
think creatively about solutions, and express a solution clearly and accurately.
high-level language? - Answer-such as python, high-level languages are portable, meaning that
they can run on different kinds of computers with few or no modifications.
low-level language - Answer-machine languages or assembly languages. Computers can only
execute programs written in low level languages
• Python runs on program called Python Interpreter. There are two ways to use it immediate
mode and script mode. - Answer-...
• In immediate mode, you type Python expressions into the Python Interpreter window, and the
interpreter immediately shows the result: - Answer-...
• The >>> is called the Python prompt. The interpreter uses the prompt to indicate that it is
ready for instructions. - Answer-...
• Script - Answer-when you can write a program in a file and use the interpreter to execute the
contents of the file
program - Answer-a sequence of instructions that specifies how to perform a computation.
input - Answer-Get data from the keyboard, a file, or some other device.
output - Answer-Display data on the screen or send data to a file or other device.
math - Answer-Perform basic mathematical operations like addition and multiplication.
