  The internet, short for "interconnected network," is a global network of computers and other devices that are connected and communicate with each other using a standardized set of protocols. It is a vast network infrastructure that spans the globe and enables the exchange of information and data between computers and users worldwide. The internet allows users to access a wide range of services and resources, including websites, email, online communication tools, file sharing, streaming media, online shopping, social networking, and much more. It provides a platform for global connectivity, enabling individuals, organizations, and governments to connect, collaborate, and share information on a global scale. At its core, the internet is built upon the principles of packet switching and the Internet Protocol (IP). Data is broken down into small packets and routed across the network based on IP addresses. This decentralized and distributed nature of the internet allows for robu

  A computer is an electronic device that is capable of receiving, storing, processing, and outputting data. It is a machine designed to perform various tasks and operations based on instructions provided by a user or pre-programmed software. In simpler terms, a computer is a device that can perform different types of calculations, manipulate data, and execute a wide range of tasks. It consists of hardware components, such as a central processing unit (CPU), memory, storage devices, input/output devices, and a user interface. The CPU, often referred to as the "brain" of the computer, carries out instructions and performs calculations. The memory (RAM) provides temporary storage for data and instructions that the CPU needs to access quickly. Storage devices, such as hard drives or solid-state drives, store data for long-term use. Input devices, such as keyboards and mice, allow users to provide instructions or input data into the computer. Output devices, such as monitors and

  There are several types of IP addresses used in computer networks. Here are the most common types: Public IP Address: A public IP address is assigned to a device directly connected to the internet. It serves as a unique identifier for the device on the global internet. Public IP addresses are provided by Internet Service Providers (ISPs) and are globally routable, allowing communication with devices across the internet. Private IP Address: A private IP address is used within a local network, such as a home or office network. These addresses are not globally unique and are meant for internal use only. Private IP addresses are defined by the Internet Assigned Numbers Authority (IANA) and are reserved for private networks. Common private IP address ranges include: IPv4 Private Addresses: Class A: 10.0.0.0 to 10.255.255.255 Class B: 172.16.0.0 to 172.31.255.255 Class C: 192.168.0.0 to 192.168.255.255 IPv6 Unique Local Addresses (ULA): FC00::/7 range Dynamic IP Address: A dynamic IP addre
