Q1. Tell me routing consideration for harness
Ans. 
Routing consideration for harness involves planning the path of wires to ensure proper organization and avoid interference.
• Consider the length of wires to minimize signal loss

• Plan for proper separation of power and signal wires to avoid interference

• Avoid sharp bends and tight corners to prevent damage to wires

• Use cable ties or harness tape to secure and organize the wires

• Consider the thermal and mechanical stress on th

Q2. Tell me factors affecting resistance of wire?
Ans. 
Factors affecting resistance of wire include material, length, cross-sectional area, and temperature.
• Material: Different materials have different resistivities, affecting resistance.

• Length: Longer wires have higher resistance due to increased collisions between electrons and atoms.

• Cross-sectional area: Thicker wires have lower resistance as there is more space for electrons to flow.

• Temperature: Resistance increases wit...read more

Q3. Difference between van neuman and harvard architecture
Ans. 
The main difference between von Neumann and Harvard architecture is the separation of data and instruction memory.
• Von Neumann architecture uses a single memory space for both data and instructions, while Harvard architecture uses separate memory spaces for data and instructions.

• Harvard architecture allows for simultaneous access to data and instructions, leading to potentially faster performance.

• Von Neumann architectur...read more
