ALGORITHM: Series of instructions or oder steps for performing an activity or solving a problem. Example: technological process
They can be solvedusing computers and programing languages. Program: Transition of an algorithm into a programing language that can be understood and processed by a computer. Exampple: Scratch and bitbloq.
TYPES
Sequencial algorithms
: The instructions are excorted one after the other in the same order as they appear
start
Selecttic algorithm
: The instruction are executed depending on whether or not a condition is net.
Start
Action1
decision
Iterative algorithim
: They have a set of informations that are repeated several times.These instructions are contained in loops that mark the beginning and the end of the repetition
start
CHARACTERISTICS
Finite
Simple and ordered
Specific instructions (no ambiguity)
GRAPHICAL REPRESENTATION
The chart used is called flow chart or flow diagram. It uses symbols coneccted by arrows to show the sequences of the actions.
Information input or output (data or result)
Process actions design and contruct
Decision (yes or no) quetions with 2 options
Terminal start and end
Flow line
: They tell the order of the actions
yes
Action 1
Action 2
Action N
End
No
Action 2
Action 3
End
Action 1
Variable
Decision
Action 2
End
