The OSI model has seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. Virtual LANs (VLANs) segment networks for better management and security. Quality of Service (QoS) prioritizes network traffic to ensure performance for critical applications. Ad Hoc networks are temporary networks created on-the-fly without a central infrastructure. WiMAX is a wireless communication standard for long-range broadband access, while Wi-Fi is a technology for wireless local area networking.

The four-digit number is 1389.
let the 4 digit number be ABCD.
First Digit is A :
Therefore; according to the question
A=B/3
B=3A
C=A+B=A+3A=4A
D=3B=3(3A)=9A
Since the last Digit is D and it can neither be double-digit nor 0 ;
Therefore ;
A=1;
B=3A=3(1)=3
C=A+B=1+3=4
D=9A=9(1)=9
Therefore, the 4 digit number is 1349.
The age of the new person is 24 years.

The speed of the train is 30 meters per second.
Which means the train will travel 180 m in 6 seconds so
We need to convert this into minutes
6×10 = 60s= 1 minute.
180×10 = 1800 m train will travel 1.8 km in 1 minute.
1.8×60 = 108 kmph
It will become 2.5 times in 10 years at the same rate.

The surface area of the cube is 864 cc.
A Statement of Work (SOW) is a formal document that outlines the specific tasks, deliverables, timelines, and responsibilities for a project or contract.
To determine realistic schedules for a project, I follow these steps:
1. Define project scope and deliverables.
2. Break down tasks into smaller, manageable components (Work Breakdown Structure).
3. Estimate the time required for each task using historical data and expert input.
4. Identify dependencies between tasks to understand the sequence of work.
5. Consider resource availability and constraints.
6. Use project management tools to create a timeline and visualize the schedule.
7. Review and adjust the schedule based on team feedback and potential risks.
8. Monitor progress regularly and be flexible to make adjustments as needed.
B alone can finish the work in 24 days.
The work done by A in 8 days is = 8/ 12 = 2/3
Means A alone completes 2/3 part of work.
Remaining work which is (1–2/3) = 1/3 is completed by B in 8–2 = 6 days
So the complete work done by B in 6/(1/3) = 18 days.
B alone can complete the work in 18 days.
Project selection methods are techniques used to evaluate and choose projects based on their potential value and alignment with organizational goals. Common methods include:
1. **Cost-Benefit Analysis**: Comparing the expected costs and benefits of a project to determine its feasibility.
2. **Scoring Models**: Assigning scores to projects based on predefined criteria to rank them.
3. **Payback Period**: Calculating the time it takes to recover the initial investment from the project's cash flows.
4. **Net Present Value (NPV)**: Assessing the profitability of a project by calculating the difference between the present value of cash inflows and outflows.
5. **Internal Rate of Return (IRR)**: Determining the discount rate that makes the NPV of a project zero, indicating its potential return.
6. **Portfolio Analysis**: Evaluating projects as part of a larger portfolio to balance risk and return.
7. **Expert Judgment**: Relying on the insights of experienced stakeholders
Yes, I understand milestones as key points in a project timeline that signify important achievements. Interdependencies refer to the relationships between tasks where one task relies on the completion of another. Resource allocation involves assigning available resources, such as time, budget, and personnel, to various tasks to ensure project success.
