INITIALIZATION
A flowchart symbol that represents a printout, such as a document or a report
INPUT/OUTPUT BOX
A flowchart symbol that indicates some particular operation.
PROCESS BOX
A flowchart symbol that represent the flow of the sequence and direction of a process
FLOW LINES
A flowchart symbol that indicates that the flow continues on a matching symbol containing the same letter somewhere else on the same page
ON-PAGE CONNECTOR/REFERENCE
A flowchart symbol that contains a number inside; indicates that the flow continues on a matching symbol containing the same number somewhere else on a different page

DECISION BOX
informal high-level description of the operating principle of a computer program or other algorithm.
PSEUDOCODE

PROGRAMMING LANGUAGE
3 levels of programming languages
- LOW LEVEL LANGUAGE
- MIDDLE LEVEL LANGUAGE
- HIGH LEVEL LANGUAGE
A level of programming language designed using zeros (0) and ones (1), hence they are critical to understand
LOW LEVEL LANGUAGE (LLL)
A level of programming language designed using some special words known as mnemonic and when we compared it to low level language, machine level is easy to understand.
MIDDLE LEVEL LANGUAGE
A level of programming language designed using simple English like words.
HIGH LEVEL LANGUAGE
What are the 3 types of translators
- COMPILER
- INTERPRETER
- ASSEMBLER
A type of translator that converts the entire source code into object code (machine code) at once; used to convert HLL into Machine code format.
COMPILER
A type of translator that converts source code into object code in line-by-line format; used to convert HLL into understandable machine code.
INTERPRETER
A type of translator that is used to convert assembly level language (low level) into machine level language.
ASSEMBLER
any collection of code, possibly with comments, written using a human-readable programming language, usually as plain text.
