Communication Models
Aristotle: Speaker → Message → Listener
Lasswell: Communication + Message + Medium + Audience = Impact
Shannon & Weaver: Information Source → Transmitter → Channel (Noise) → Receiver → Destination
Schramm’s: Encoder/Interpreter/Decoder → Message → D/I/E → Message…
Berlo’s: Source → (E) Message → Channel → (D) Receiver
Proposed: Sender; /\ Life Experience; Message; Noise; X Life Experience; Receiver, Amplified, Accepted; Rejected

Binary to Decimal Conversion
Binary/Decimal:
- List the powers of 2 from right to left, starting with #1. Increment the exponent by 1 for each power. Stop when the amount of elements in the list is equal to the amount of digits in the binary number.
- Only if the digit is a 1, write down its corresponding power of 2.
- Finally, add all the numbers to get the answer.
Bus Speed and Width
Bus Speed: The number of bits or bytes that the bus sends in a unit of time (a second is the most common). For example, a 100

Understanding Electricity: Voltage, Current, Power, and Resistance
Voltage is the potential difference between two points in an electric circuit and the force required to push electrons in a circuit, measured in volts. Current is the flow of electric charge through a circuit, measured in amperes. Power is the rate at which energy is transferred, measured in watts. Resistance is the opposition to the flow of electric current, measured in ohms. Ohm’s law states that the current

Thermodynamics: Systems, Equilibrium, Laws, and Processes
Thermodynamic Systems
A thermodynamic system is a specific portion of matter with a definite boundary on which our attention is focused. The system boundary may be real or imaginary, fixed or deformable.
There are three types of systems:
- Isolated System – An isolated system cannot exchange energy and mass with its surroundings. The universe is considered an isolated system.
- Closed System – Across the boundary of the closed system, the transfer of energy takes place, but the transfer of mass doesn’t

Binary to Decimal Conversion
Here’s how to convert binary numbers to decimal:
- List the powers of two from right to left. Start with the number 1 (which is 20). Increment the exponent by one for each subsequent power. Stop when the number of elements in the list equals the number of digits in the binary number.
- Write down the corresponding power of two only if the binary digit is a 1.
- Add all the numbers from step 2 to get the decimal equivalent.

- Bus Speed: This is the number of
