Study Notes
Boolean Algebra and Computers
- George Boole suggested that logical thought could be represented through mathematical equations.
Boolean Algebra Values
- Boolean algebra deals with two values: 0 (false) and 1 (true).
Computers and Boole's Laws of Thought
- Claude Shannon was among the first to see the connection between computers and Boole's Laws of Thought.
Computers in the Mid-20th Century
- In the middle of the twentieth century, computers were perceived as giant calculators.
The Essence of the Machine
- The essence of the machine is that it can process information, make decisions, and provide results.
Address Decoder
- An address decoder with 4 inputs can select 2^4 = 16 memory locations.
Multiplexer
- A multiplexer with 8 inputs needs 3 control lines to select among the inputs.
- A multiplexer is an electronic switch that selects one of several input signals and forwards it to a single output line.
Computer Memory
- The flip-flop is the fundamental circuit of computer memory.
D Flip-Flop
- The output of a D flip-flop changes on the clock edge (rising or falling).
Binary Counter
- At each clock pulse, the low-order bit in a binary counter toggles (changes state).
