 HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) are fundamental technologies used in web development to create and style web pages. They work together to structure and design the content of a webpage. HTML is the standard markup language for creating the structure and layout of web pages. It uses tags to define elements such as headings, paragraphs, images, links, tables, and forms. HTML provides a hierarchical structure to organize and present content on the web. It is a markup language, meaning it uses tags to define the structure and semantics of the content rather than specifying how it should be visually displayed. CSS, on the other hand, is a style sheet language used to describe the presentation and visual appearance of HTML documents. It separates the content and structure of a webpage from its presentation, allowing developers to control the look and feel of a website. With CSS, you can define styles for elements defined in HTML, including colors, fonts,...

 Installing an operating system on a computer involves a few steps that vary depending on the specific operating system you want to install. Here's a general overview of the installation process: 1. Obtain the installation media: You'll need the installation media for the operating system you want to install. This could be a DVD, a USB flash drive, or a downloaded ISO file. 2. Backup your data: Before proceeding with the installation, it's essential to back up any important data on your computer to prevent data loss. 3. Configure your computer's BIOS/UEFI settings: Access your computer's BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) settings. The method for accessing these settings varies depending on your computer manufacturer. Look for a prompt during the boot process or consult the computer's manual. In the BIOS/UEFI settings, ensure that your computer is set to boot from the installation media (DVD or USB) instead of the ha...

 A hacker is an individual who uses their computer programming and technical skills to gain unauthorized access to computer systems or networks. While the term "hacker" can have both positive and negative connotations, it is commonly associated with individuals engaged in illegal or malicious activities. Hackers can be classified into different types based on their intentions and motivations. Here are some common types of hackers: 1. Black Hat Hackers: Black hat hackers, also known as "crackers," are individuals who engage in malicious activities and unauthorized intrusion into computer systems or networks. Their intentions are typically malicious, and they may steal sensitive data, disrupt systems, distribute malware, or engage in other illegal activities for personal gain or to cause harm. 2. White Hat Hackers: White hat hackers, also known as "ethical hackers" or "security researchers," are individuals who use their hacking skills for construc...

 The CPU (Central Processing Unit) is the primary component of a computer that performs most of the processing tasks. It consists of several key parts that work together to execute instructions and perform calculations. Here are the main components of a CPU: 1. Control Unit (CU): The control unit is responsible for coordinating and controlling the operations of the CPU. It fetches instructions from memory, decodes them, and directs the appropriate data to the arithmetic logic unit (ALU) for processing. It also manages the flow of data between different parts of the CPU and external devices. 2. Arithmetic Logic Unit (ALU): The ALU performs mathematical and logical operations on the data provided by the control unit. It can perform basic arithmetic operations like addition, subtraction, multiplication, and division. Additionally, the ALU can execute logical operations such as AND, OR, and NOT on binary data. 3. Registers: Registers are small, high-speed memory units located within th...
