Web Publishing, Hosting, and Development Fundamentals
Once you have designed and built a website on your local computer, it only exists on your local hard drive. Web Publishing is the complete process of preparing, uploading, and maintaining your website files on the internet so the public can access them.
The most critical phase of web publishing is Web Hosting—renting space on a web server that stays active 24/7.
1. The 4 Main Types of Web Hosting
When choosing a server space, you need to pick a structure that matches your website’s traffic volume,

JavaScript Form Object
The Form Object in JavaScript represents an HTML form. It is used to access and control form elements such as text fields, buttons, checkboxes, and radio buttons. Using the form object, developers can handle form data and perform validation easily. Forms are accessed through the document.forms collection.
Syntax
document.forms["formname"]
Example: document.forms["myform"] (Accesses the form named ‘myform’)
Properties
- action: Specifies the URL where form data is sent.
- method: Specifies
C++ Object Oriented Programming: Core Concepts and Features
UNIT–I: Object Oriented Programming Concepts
1. Procedural Language and Object Oriented Approach
Procedural programming is a method in which a program is divided into small procedures or functions. It mainly focuses on the sequence of actions to be performed. Data and functions are treated separately, which may reduce security because global data can be accessed from different parts of the program. Languages like C follow the procedural approach. Object Oriented Programming (OOP), on the other hand,

In C++, the lifecycles of objects are managed automatically or dynamically through two special types of member functions: Constructors and Destructors. They control how memory is allocated, initialized, and cleaned up when an object is created and destroyed.
1. What is a Constructor?
A constructor is a special member function that is automatically called when an object of a class is instantiated. It has the same name as the class and does not have a return type (not even void). Its primary purpose

SQL Injection Attack Types
Direct Attack: An attacker (Eve) sends a malicious request directly to the server (Bank.com).
Cross-Site: Alice has two tabs open: a sensitive site (Bank) and a malicious site (Evil.com). The malicious site tries to influence the sensitive one.
Third-Party: A legitimate site (News.com) loads an advertisement from a malicious domain (EvilAds.com).
Cookie Security and Session Hijacking
Mechanism: HTTP is stateless. To “remember” Alice,

5G Frequency Domain Structure
- Resource Element (RE): Smallest unit = 1 subcarrier × 1 OFDM symbol.
- Resource Block (RB): 12 consecutive subcarriers in the frequency domain. Unlike LTE (2D), 5G RB is 1-dimensional (frequency only).
- Scalable Subcarrier Spacing (Numerology): 15, 30, 60, 120, 240 kHz — selected based on frequency band and use case.
- Bandwidth Parts (BWP): UE can be configured to use only a portion of the total carrier bandwidth, saving battery for IoT devices.
- Maximum Single-Carrier Bandwidth:
