Study Notes

Logic Gates

Logic gates turn ON (1) when a certain condition is true and OFF (0) when the condition is false
They check whether the input information follows a certain rule and output true (ON) or false (OFF)

Binary System

Computers think in terms of ON and OFF, which is equivalent to 1 and 0
Input refers to the information given to a logic gate, and output refers to what it produces

Number Systems Conversion

Binary-to-Decimal conversion method is not specified
Decimal-to-Octal conversion method is the repeated-division method

Microprocessors and Microcomputers

A computer system has three major parts
Pipelining is the simplest form to allow the CPU to fetch and execute instructions at the same time
Fetch and execute times can be different in pipelining
Pipelining is also referred to as copy instructions
Types of data transfer instructions include:
- Move instructions: used to move data between memory locations or between a memory location and a register
