Concept of FEM and Procedure
Finite Element Method (FEM) is a numerical technique used to solve complex engineering problems by dividing a large system into smaller, simpler parts called finite elements.
Instead of solving the whole structure at once, FEM solves each small element and combines the results to get an approximate solution.
Procedure of FEM:
Design Thinking is a non-linear, iterative process used to understand users, challenge assumptions, re-define problems, and create innovative solutions. To illustrate this, let’s use the example of improving the commute experience for urban cyclists.
1. empathize (finding the problem)
The first stage is about gaining an empathetic understanding of the problem you are trying to solve. This involves observing and engaging with people to understand their experiences and motivations.

E.F. Codd, a pioneer in the field of relational databases, defined 12 rules (numbered 0 to 12) to determine whether a Database Management System (DBMS) can be considered a truly Relational Database Management System (RDBMS).
For a 10-mark answer, here is a breakdown of these rules with examples.
Rule 0: The Foundation Rule
For a system to qualify as an RDBMS, it must use its relational facilities exclusively to manage the database. If a system requires non-relational sub-languages to access data,...

Q1. Difference between AC Supply and DC Supply
AC (Alternating Current) Supply
Alternating current is the type of electrical supply in which the magnitude and direction of current change periodically with time. The waveform of AC is usually sinusoidal. AC is used for power transmission because it can be easily stepped up or stepped down using transformers.
Characteristics of AC
Direction changes periodically
Has frequency (...
A computer network is a system of interconnected devices that communicate and share data using communication protocols.
Node: Any device connected in a network.
Protocol: Rules for communication (TCP/IP, HTTP).
IP Address: Unique number assigned to each device.
DNS: Converts domain names into IP addresses.
Firewall: Protects network from unauthorized access.
PAN: Connects personal devices within short range.
