Q1. OSI model in detail
Ans. 
The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven layers.
• The OSI model stands for Open Systems Interconnection model.

• It consists of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Each layer has specific functions and communicates with the adjacent layers.

• Example: The Physical layer deals with the p...read more

Q1. Explain First angle projection
Ans. 
First angle projection is a method of representing a 3D object in 2D by projecting the object onto a plane from the perspective of the viewer.
• In first angle projection, the object is placed in the first quadrant of the viewing plane.

• The top view is placed above the front view and the side view is placed to the right of the front view.

• This method is commonly used in Europe and Asia.

• It is important to understand the orie...read more

Q2. Earthing types which one preferred based on soil conditions
Ans. 
The preferred earthing type depends on soil conditions, such as resistivity and moisture content.
• Earthing types like plate earthing, rod earthing, and pipe earthing are preferred based on soil resistivity.

• In areas with high moisture content, rod earthing is preferred as it provides better conductivity.

• In areas with low resistivity, plate earthing is preferred as it offers a larger surface area for better grounding.

• Soil...read more

Q2. What is JK flip flop
Ans. 
JK flip flop is a type of sequential logic circuit that has two inputs (J and K) and two outputs (Q and Q').
• JK flip flop is a type of bistable multivibrator circuit.

• It has two inputs - J (set) and K (reset), and two outputs - Q and Q'.

• The outputs of a JK flip flop change state (toggle) based on the inputs and the clock signal.

• It can be used to store one bit of information or as a frequency divider.

• Example: JK flip flop...read more
