codio unit 1

strong password

A password that is easy for a user to remember but would be difficult for someone else to guess.

algorithm

A set of instructions that accomplishes a specific task.

abstraction

The process of reducing complexity by focusing on the main idea.

sequencing

The application of each step of an algorithm in the order which the code statements are given.

selection

Determines which parts of an algorithm are executed based on a condition being true or false.

iteration

A repeating portion of an algorithm repeats a specified number of times or until a given condition is met.

encryption

The process of encoding data to prevent unauthorized.

decryption

Is the process of decoding the data.

programming language

The language computers use to communicate.

problem

A general description of a task that can (or cannot) be solved algorithmically.

instance of a problem

A specific task that needs to be solved with specific input.

decision problem

A problem with a yes/no answer.

optimization problem

A problem with the goal of finding the best solution among many.

decidable problem

A problem for which an algorithm can be written to produce a correct output for all inputs.

undecidable problem

A problem in which no algorithm can be constructed that always leads to correct yes-or-no answer .

scalability

The capacity for a system to change in size and scale to meet new demands/data.

efficiency

An estimation of the amount of computational resources used by an algorithm.

linear or sequential search

Algorithms check each element of a list in order until the desired value is found or all elements in the lit have been checked.

binary search

Starts at the middle of a sorted data set of numbers and eliminates half of the data this process repeats until the desired value is found or all elements have been eliminated.

heuristic

An approach to a problem that produces a solution that may not be the best way but its still good.

algorithmic bias

When a system discriminates against certain individuals or groups and creates unfair outcomes for some and better outcomes for others.

high-level language

The languages we can read

low-level language

Computer language ex:binary
