HTML (HyperText Markup Language) is the standard language used to create the structure of web pages. It is not a programming language; rather, it is a markup language that tells the web browser how to display content like text, images, and links.
It uses a system of tags (keywords enclosed in angle brackets like <html>) to wrap around content and give it meaning.
<h1> to <h6> (Heading Tags)These tags are used to define headings on a page. <h1> is the most important (main
SQL Data Types:- SQL data types specify the type of data that can be stored in a database table. Choosing the correct data type helps in efficient storage, better performance, and data integrity.
1. Numeric Data Types:- These are used to store numbers.
INT / INTEGER – Stores whole numbers
Small int / BIGINT – Stores small or large integers
DECIMAL(p,s) / NUMERIC – Stores fixed-point numbers
FLOAT / REAL – Stores floating-point numbers
2. Character (String) Data Types:- These are used
JavaScript (often abbreviated as JS) is one of the core technologies of the World Wide Web, alongside HTML and CSS. While HTML provides the structure and CSS provides the style, JavaScript provides the interactivity.
It is a high-level, interpreted programming language that allows you to implement complex features on web pages—from updating content dynamically and controlling multimedia to animating images and handling user input.

4 Functions of courts: Due Process, Crime Control, Rehabilitation, Bureaucratic
Jurisdiction (Geographic, Concurrent)
Trial Courts - first level, hears evidence, issues verdict
Appellate Courts - review rulings for legal error, no new evidence
Dual Court System - separate federal and state court systems with shared authority
Jurisdiction of the Supreme Court - original (state/ambassadors), appellate (from lower)
Supreme Court Decisions - Plurality: most votes, not majority, Concurring: agrees, different
Origins & Composition of Life (Ch. 1, L2)
• Earth formed: ~4.54 bya (textbook consensus).
• Prebiotic world: Before life emerged (~4.5–3.5 bya), atmosphere had H₂O, N₂, CO₂, CH₄, NH₃, SO₂, energy from lightning/UV.
• First evidence of life: ~3.5 billion years ago.
Composition of life
• 70% water.
• Major dry weight: C, H, O, N (87%), P, S, K, Ca, Mg.
Functional groups (must know cold):
• Amine (can be + at pH 7).
• Carboxyl (– at pH 7).
• Alcohol (–OH).
• Thiol (–SH)...
Discuss various string operators in python 1)concentration operator : the +operator is used to concentrate 2 or more thing
Python Code str1 = "Hello"
str2 = "World"
print(str1 + " " + str2) Output: Hello World
2)repeational operator : *operator is used to repeat a string a specified no of time
Python Code str1 = "Hello"
print(str1 * 3) # Output: HelloHelloHello
3)indexing operation ([ ]):[ ] operator is used to aceesed a character a specified index at string
Python code :str1 = "Hello"

Modular Programming
Modular programming is a software design technique that divides a program into smaller, independent, and reusable units called modules or functions. Each module performs a specific task, which helps in organizing, testing, and debugging programs more efficiently. By breaking a large problem into manageable pieces, programmers can focus on one module at a time, reducing complexity and improving readability. Modules can be developed, tested, and maintained separately,

Extracting Digits of a Number (Left to Right and Right to Left)
Extracting digits of a number is a fundamental programming task used in various computational problems, such as reversing a number, checking for palindromes, or performing digit-based calculations. There are two main approaches: right-to-left extraction and left-to-right extraction. In right-to-left extraction, the modulus operator (%) is used to obtain the last digit of the number, while integer division (/) removes the last

Problems and Problem Instances
A problem in computer science is a clearly defined task or situation that requires a solution using logical and computational methods. It describes what needs to be achieved without specifying how to achieve it. A problem usually includes input data, required output, and certain constraints that must be satisfied. For example, “finding the maximum number in a list” is a problem statement. A problem instance is a specific example of that problem with actual
