Computer Networks - Physical and Data Link Layer

Why does the physical layer handle raw bit transmission in a network?

ABecause it sends bits as electrical or light signals without interpreting them

BBecause it encrypts data for security

CBecause it manages user applications

DBecause it controls network routing

Step-by-Step Solution

Solution:

Step 1: Understand the role of the physical layer
The physical layer is responsible for sending raw bits as signals like electrical pulses or light, without changing their meaning.
Step 2: Differentiate from other layers
Other layers interpret data or manage connections, but the physical layer only moves bits between devices.
Final Answer:
Because it sends bits as electrical or light signals without interpreting them -> Option A
Quick Check:
Physical layer = raw bit transmission [OK]

Quick Trick: Physical layer sends raw bits as signals, no data interpretation [OK]
