An internetwork connects two or more computer networks like LANs or WANs using devices that configure local addressing schemes. There are two main types of internetworks: extranets and intranets. An extranet restricts access between an organization's network and external users through login credentials, while an intranet only allows internal access among an organization's employees to share information and resources using internet protocols.

A computer network connects computers together to share resources and information. The first major computer network was ARPANET, funded by the US Department of Defense. There are several types of computer networks classified by size: local area networks (LANs) connect computers in a small area like a home or office; wide area networks (WANs) connect LANs over large geographic areas using technologies like phone lines; and metropolitan area networks (MANs) connect organizations in a city using dedicated hardware. An internetwork connects two or more distinct networks, and the Internet is the largest internetwork. Intranets connect computers within an organization, extranets provide limited access to outsiders, and the Internet allows open access to information forInternet and intranet
Internet and intranetSubrata Kumer Paul

The document defines and compares intranets, extranets, and the internet. An intranet allows restricted access within an organization, an extranet expands access to authorized outsiders like suppliers, and the internet provides open access worldwide. It also defines VPNs as using public networks like the internet to connect private networks, and VLANs as logical groupings of devices that appear on the same network despite geographical distribution. The key differences are levels of access and size of the network.01 elements of modern networking by nader elmansi

The document defines and compares Internet, intranet, and extranet. The Internet is a global network of interconnected computers accessible to anyone. An intranet is a private internal network, similar to the Internet, contained within an organization. An extranet extends an organization's intranet to allow access to selected external partners and customers while maintaining security. Types of extranets include public, private, and virtual private networks (VPNs) which use encryption tunnels for secure transmission over public networks.Internet vs intranet vs extranet

The document provides an introduction to the Internet, describing its origins from ARPANET and how it functions as a network of interconnected computer networks that allows users to access data remotely. It discusses that the Internet relies on protocols like TCP/IP to allow different systems to communicate and that no single organization owns or governs the Internet, with responsibilities divided among groups that set standards, discuss technical issues, and provide registration services. It also outlines some basic requirements to connect to the Internet like a modem, ISP, and special programs to control communication of data over hardware components.1 油 油please describe the following and share which you plan to appl.docx

This document discusses computer networks and the internet. It explains that a network connects computers using cables or wireless devices. The most common type of cable used is Ethernet, which connects to the network interface controller (NIC) of each computer. For devices to communicate on a network, they must follow a set of protocols or standards. There are different types of networks including local area networks (LANs), wide area networks (WANs), and internetworks. The internet uses protocols like IP and domain name systems to connect networks on a global scale. Key components that enable internet communication are routers, which direct traffic between networks, and browsers, which are used to access and view web documents and pages on the world wide web.UNIT 1.pdf

A computer network (CN) is a group of devices that share resources over a network, with each device represented as a network node. The devices communicate with each other using standard protocols to send or receive data.
Computers on a network can be linked through cables, radio waves, telephone lines, infrared light beams, or satellites. The network can also include other devices that help in communication, known as network devices.
Here are some types of computer networks:
PAN (Personal Area Network): The smallest and simplest type of network
LAN (Local Area Network): The most frequently used network, connecting computers within a limited area, such as a single office or building
MAN (Metropolitan Area Network): A type of network
WAN (Wide Area Network): An enterprise network spanning cities, buildings, and even countries
Wireless networking is about creating and managing wireless connections, commonly used in Wi-Fi. This involves setting up Wi-Fi routers, securing them with passwords, and allowing devices to connect to a network without using physical cables. Internet, intranet and extranet

The increasing use of Industrial Internet of Things (IIoT) devices has brought about new security vulnerabilities, emphasizing the need to create strong and effective security solutions. This research proposes a two-layered approach to enhance security in IIoT networks by combining lightweight encryption and RNN-based attack detection. The first layer utilizes Improved Elliptic Curve Cryptography (IECC), a novel encryption scheme tailored for IIoT devices with limited computational resources. IECC employs a Modified Windowed Method (MWM) to optimize key generation, reducing computational overhead and enabling efficient secure data transmission between IIoT sensors and gateways. The second layer employs a Recurrent Neural Network (RNN) for real-time attack detection. The RNN model is trained on a comprehensive dataset of IIoT network traffic, including instances of Distributed Denial of Service (DDoS), Man-in-the-Middle (MitM), ransomware attacks, and normal communications. The RNN effectively extracts contextual features from IIoT nodes and accurately predicts and classifies potential attacks. The effectiveness of the proposed two-layered approach is evaluated using three phases. The first phase compares the computational efficiency of IECC to established cryptographic algorithms including RSA, AES, DSA, Diffie-Hellman, SHA-256 and ECDSA. IECC outperforms all competitors in key eneration speed, encryption and decryption time, throughput, memory usage, information loss, and overall processing time. The second phase evaluates the prediction accuracy of the RNN model compared to other AI-based models DNNs, DBNs, RBFNs, and LSTM networks. The proposed RNN achieves the highest overall accuracy of 96.4%, specificity of 96.5%, precision of 95.2%, and recall of 96.8%, and the lowest false positive of 3.2% and false negative rates of 3.1%.

- 2. What is Internetwork and what are the types of Internetwork? An internetwork is defined as two or more computer network LANs or WAN or computer network segments are connected using devices, and they are configured by a local addressing scheme. This process is known as internetworking. An interconnection between public, private, commercial, industrial, or government computer networks can also be defined as internetworking. An internetworking uses the internet protocol. The reference model used for internetworking is Open System Interconnection(OSI).
- 3. Types Of Internetwork: 1. Extranet 2. Intranet 1. Extranet An extranet is a communication network based on the internet protocol such as Transmission Control protocol and internet protocol. It is used for information sharing. The access to the extranet is restricted to only those users who have login credentials. An extranet is the lowest level of internetworking. It can be categorized as MAN, WAN or other computer networks. An extranet cannot have a single LAN, at least it must have one connection to the external network.
- 4. Internetworking 2. Intranet An intranet is a private network based on the internet protocol such as Transmission Control protocol and internet protocol. An intranet belongs to an organization which is only accessible by the organization's employee or members. The main aim of the intranet is to share the information and resources among the organization employees. An intranet provides the facility to work in groups and for teleconferences.
