Lesson 1 Flashcards
It is a way of representing mechanical, electrical, system processes, and other objects and information in a form of symbols
Technical Drawing
A language with which we can store and transmit information
Technical Drawing as a Language
It is a graphical representation of an algorithm and it is composed of symbols
Flowchart
It is a process or a set of rules to be followed in calculations or other problem-solving operations
Algorithm
Theses are the commands or any programming languages to execute a flowchart
Pseudocode
What are the basic flowchart symbols?
Terminal/Terminator (Oval)
Flowlines (Lines)
Input/Output (Paralellogram)
Processing (Rectangle)
Decision (Diamond)
Off-page connector (Upside down Pentagon)
On-page connector (Circle)
It shows controls over document flow through systems
Document flowchart
It is used to show the channels through which data is transmitted rather than the flow of controls
Data flow diagram
It shows the physical or resource level controls, displays the flow of algorithms, and displays the flow of data within a system and the decisions made to control events
System flowchart
It is used to solve particular problems such as a mathematical problem solving and others
Program flowchart
It is a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer
Algorithm
Algorithm takes input data, which can be in various formats, such as numbers, text or images
Input
It processes the input data through a series of logical and mathematical operations, manipulation and transforming it as needed
Process
It is a result, decision, or some other meaningful information
Output
It accomplishes tasks quickly and with minimal resources
Efficiency
