Subnetting Basics Tutorial
This document provides an introduction to subnetting basics. It begins by covering prerequisite knowledge, including classful network addressing, subnet masks in dotted decimal and prefix length notation, and the default subnet masks for Classes A, B, and C. It then explains how to identify the subnet and host bits when given an IP address and prefix length. The document demonstrates how to calculate the number of subnets and hosts available by using binary math equations. It provides an example of analyzing an IP address of 192.168.32.158/28 to determine its subnet ID and host ID.
TCP/IP Model
The TCP/IP model has four layers: Application layer, Transport layer, Internet layer, and Network Access layer. The Application layer contains protocols that provide services to users like web browsing, email, and file transfers. The Transport layer deals with manipulating data and preparing it for delivery through the network using protocols like TCP and UDP. The Internet layer determines routing and addresses using IP addressing and routing protocols. The Network Access layer is responsible for transmitting bits and bytes across physical network connections using devices like hubs, switches, and network interface cards.
TCP-IP Reference Model
The document discusses the TCP/IP protocol suite and compares it to the OSI model. It describes the layers of the TCP/IP model including the physical, data link, internet, and transport layers. The transport layer uses TCP and UDP, with TCP being connection-oriented and reliable, while UDP is connectionless. The internet layer uses IP to transport datagrams independently. The OSI model has 7 layers while TCP/IP has 5 layers that do not directly correspond to the OSI layers.
Ip address
IP addresses are 32-bit numbers that uniquely identify devices on a network. They allow for file transfers and email communication using the Internet Protocol. There are five classes of IP addresses - A, B, C, D, and E - which are divided into ranges to define large, medium, and small networks. Users can determine the IP address of their own device or other computers and websites using commands like ipconfig and ping.
TCP/IP Presentation
This document discusses the four layers of the TCP/IP model and how they coordinate with each other. It explains the processes of encapsulation and decapsulation as data moves between layers. Encapsulation involves each layer adding a header to data packets as they move down the stack, while decapsulation is the reverse process of removing headers as packets move up the stack at their destination. Figures and references are provided to illustrate these TCP/IP concepts.
Osi model vs TCP/IP
The document compares the OSI model and the TCP/IP model. The OSI model consists of 7 layers and defines a standardized protocol-independent framework. The TCP/IP model has 4 layers and was developed based on the protocols used for the Internet. Key differences are that OSI has stricter layering while TCP/IP layers are more loosely defined, and TCP/IP focuses on the specific protocols used for Internetworking while OSI aims to be protocol-independent.
Ip address and subnetting
IP addressing and subnetting allows networks to be logically organized and divided. The key objectives covered include explaining IP address classes, configuring addresses, subnetting networks, and advanced concepts like CIDR, summarization, and VLSM. Transitioning to IPv6 is also discussed as a way to address the depletion of IPv4 addresses and improve security.
TCP/IP Basics
TCP/IP is a set of communication protocols used to connect devices on the internet. It includes lower level protocols like IP that handle basic transport of data and higher level protocols like TCP that ensure reliable delivery of data between applications. TCP establishes connections between clients and servers that allow for reliable transmission of data streams. UDP provides a simpler transmission model without ensuring delivery but is useful for applications like broadcasting.
TCP/IP Network ppt
The document provides an overview of the TCP/IP model, describing each layer from application to network. The application layer allows programs access to networked services and contains high-level protocols like TCP and UDP. The transport layer handles reliable delivery via protocols like TCP and UDP. The internet layer organizes routing with the IP protocol. The network layer consists of device drivers and network interface cards that communicate with the physical transmission media.
Internet protocol (ip) ppt
IP specifies the format of packets, also called #datagrams, and the addressing scheme. Most networks combine IP with a higher-level protocol called Transmission Control Protocol (TCP), which establishes a virtual connection between a destination and a source.

IP Addressing & subnetting strategy
The document discusses the Internet Protocol (IP) which is the cornerstone of the TCP/IP architecture and allows all computers on the Internet to communicate. There are two main versions of IP - IPv4, the currently used version, and IPv6 which is intended to replace IPv4 and includes improvements like longer addresses. IP addresses are 32-bit for IPv4 and 128-bit for IPv6. Strategies like private addressing and Classless Inter-Domain Routing (CIDR) help conserve the limited number of available IP addresses.

Lecture2
The document discusses the OSI model, which is a standard networking framework that defines 7 layers of communication. It was developed by ISO in 1984 to establish a common way for diverse communication systems to interconnect. Each layer performs a specific task, passing data to the next layer. Data moves down the layers at the source and up at the destination, with each layer adding header information. This layered approach separates functions and makes the network easier to manage and troubleshoot. The TCP/IP model is also discussed as an alternative networking framework.

2. It also discusses common networking terms like hubs, bridges, routers, and gateways and explains how they relate to the OSI model layers.
3. Finally, it briefly introduces the concept of subnet masks and their role in defining the network and host portions of an IP address.
PC 106 PPT-06
The document discusses the OSI model, which defines 7 layers for network communication: Physical, Data Link, Network, Transport, Session, Presentation, and Application. It was developed by ISO to standardize network architectures and allow components from different vendors to communicate. Each layer has a set of well-defined functions and builds upon the layers below it, with standards developed independently for easier introduction and less effect of changes on other layers. This model divides network communication into simpler components and encourages standardization.
unit-1fon (1).pptx
The document discusses computer networks and networking concepts. It defines a computer network as an interconnection of two or more computers that allows users to share information and resources. The document describes two common network models - the peer-to-peer and client/server models. It also explains the seven layer OSI reference model and compares it to the four layer TCP/IP model. Finally, it categorizes different types of networks including LANs, MANs, WANs, PANs, wireless networks, and home networks.
Osi model
The document discusses the OSI model, which is a standard networking framework that defines 7 layers for network communication. Each layer provides services to the layer above it and receives services from the layer below it. The layers are physical, data link, network, transport, session, presentation, and application. The model separates network functions into logical layers to simplify network design, debugging, and management. It allows interoperability between different types of networks and systems.
THE COMPLETE OSI MODEL
The document discusses the OSI reference model, which is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system without regard to their underlying internal structure and technology. The OSI model structures network architecture into 7 layers, with each layer performing a specific set of functions. It defines the protocols used for communication between the layers of networked systems and allows networks to work together. The 7 layers are physical, data link, network, transport, session, presentation, and application layers. Each layer focuses on a specific task and provides services for the layer above it, hiding the details of its own implementation and the layers below it.
layering.ppt
The document discusses layered network models including OSI and TCP/IP. It provides details on the layers of each model, the functions of each layer, and examples of protocols used. Key points covered include how data is encapsulated as it moves through the layers, with each layer adding header information, and how the layers allow for standardization and modularity in network communication.
