This document provides instructions for setting up an internet connection using either a wired or wireless modem. It discusses the purpose of the lesson, which is to familiarize students with the tools used to set up an internet connection. It also defines what an Internet Service Provider (ISP) is and lists some of the leading ISPs in the country. The document outlines the materials needed and steps to set up a wired or wireless internet connection, including plugging the modem into an outlet, connecting an Ethernet cable between the modem and computer, and enabling the network connection on the computer. It includes tasks for students to design a poster of a networked connected to the internet and to present their output through a PowerPoint presentation.
internet protocols
The document discusses several common network protocols including the Internet Protocol which governs communication between computers. It describes protocols like TCP which specifies how packets are exchanged between networks, IPX/SPX originally used by Novell, and HTTP which governs file exchanges on the World Wide Web. The document also covers protocols for file transfer, secure connections, email delivery, and other functions.
Internet Protocols
This presentation provides an overview of several important internet protocols:
- Internet Protocol (IP) delivers data packets from source to destination hosts and defines packet sizes. IPv4 and IPv6 are major versions.
- Transmission Control Protocol/Internet Protocol (TCP/IP) is a suite of protocols that govern how data travels across networks. It has two main components - TCP breaks data into packets and verifies delivery, while IP envelopes and addresses data.
- File Transfer Protocol (FTP) allows file transfers across TCP networks and uses separate control and data connections between clients and servers located on FTP servers.
- Hypertext Transfer Protocol (HTTP) governs web page transfers and uses URLs to identify and locate resources on the network
Internet protocol
The document discusses Internet Protocol (IP) and Transmission Control Protocol (TCP). It explains that IP allows data packets to be addressed and routed through a network without a direct link between sender and receiver. TCP is a set of rules that defines how computers address and send data to each other. The purpose of IP is to define the basic unit of data transfer (datagram) and perform routing functions. Each datagram contains a header and data. IP addresses uniquely identify devices on the internet and are expressed in decimal format for human readability.
Protocols in computer network
Protocols define rules and standards for communication in computer networks. The document discusses several key network protocols including TCP/IP, POP3, SMTP, IMAP, VoIP, RTSP, HTTPS, DHCP, ICMP, UDP, FTP, ARP, Telnet and the OSI model. TCP/IP is the most widely used protocol suite consisting of TCP and IP which were the first networking protocols. Other protocols discussed include those for email (POP3, SMTP, IMAP), streaming media (RTSP), secure communication (HTTPS), network configuration (DHCP), error handling (ICMP), file transfer (FTP), address resolution (ARP), and remote terminal access (Telnet).
Internet Protocols
The document discusses network models and protocols. It introduces the OSI reference model and TCP/IP model. The OSI model has 7 layers from physical to application layer. TCP/IP has 4 layers from network access to application layer. Protocols are conventions that control connection and data transfer between endpoints. Encapsulation involves adding headers to data for routing through the layers. Common protocols and their functions are also described.
internet protocol
The document discusses several internet protocols including Internet Protocol (IP), File Transfer Protocol (FTP), Hypertext Transfer Protocol (HTTP), Secure Sockets Layer (SSL), Telnet, and Gopher. IP is the basic protocol that defines how data is sent between computers on the internet. FTP allows file transfers between systems, HTTP is used for web pages, and HTTPS provides encryption through SSL for secure communication. Telnet allows remote login to systems, and Gopher provides menu-based browsing of internet resources.
internet protocol
The document discusses several internet protocols including:
- IP which delivers data packets between hosts and includes addressing tags through encapsulation.
- TCP/IP which establishes communication between networks and provides host access to the internet.
- Ipv4 and Ipv6 which are internet protocols for carrying data packets with Ipv6 supporting more nodes.
- Early protocols for file retrieval like FTP, Gopher, and Telnet which allowed downloading and using remote files and applications with varying levels of description.

Internet protocol (ip)
There are several types of IP addresses including public, private, static, and dynamic addresses. Public IP addresses are associated with an entire network while private IP addresses uniquely identify devices within a home network. Static IP addresses never change while dynamic IP addresses are temporary and change each time a device connects.
IP addresses are also classified based on version (IPv4 or IPv6), address space (A, B, C, D, E classes), and function (unicast, multicast, broadcast, anycast). Key differences between classes include the number of bits used for network vs. host identification and the total number of possible networks. Specific rules govern how network and host IDs are assigned to ensure unique identification of devices.

"Web Systems and Technologies" refer to the comprehensive landscape of software, protocols, frameworks, and methodologies that collectively power the World Wide Web. This domain encompasses everything from the fundamental building blocks of the internet to the sophisticated web applications and services we interact with on a daily basis. It's a multidisciplinary field that combines computer science, information technology, design, and user experience to create a seamless and interactive online experience.
Key components of Web Systems and Technologies include:
Web Development: This involves the creation of websites and web applications. It includes front-end development (the user interface and interactions), back-end development (server-side logic and databases), and full-stack development (combining both front-end and back-end skills).
Web Standards and Protocols: These are the rules and guidelines that ensure consistency and interoperability on the web. Examples include HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), and HTTP (Hypertext Transfer Protocol).
Web Servers and Hosting: Web servers are computers or software that store and deliver web content to users. Hosting involves providing the infrastructure and services to make websites accessible on the internet.
Client-Side Technologies: These are the technologies that run in a user's browser and provide interactive experiences. JavaScript is the most common language used for this purpose.
Server-Side Technologies: These are technologies that run on the web server and handle tasks like processing user requests, interacting with databases, and generating dynamic content. Common server-side languages include Python, Ruby, PHP, and Node.js.
Web Frameworks: These are pre-built libraries and tools that simplify and expedite the web development process. Examples include React, Angular, Vue.js, Django, Ruby on Rails, and Flask.
Databases: Web applications often rely on databases to store and manage data. Different types of databases include relational databases (e.g., MySQL, PostgreSQL) and NoSQL databases (e.g., MongoDB, Redis).
Web Security: This aspect focuses on protecting user data, preventing unauthorized access, and ensuring the overall security of web applications. Techniques include encryption, authentication, and authorization.
Web Accessibility: This involves designing and developing websites and applications that can be used by people with disabilities. It ensures that the web is inclusive and usable for all users.
Responsive Design: With the diversity of devices accessing the web, responsive design ensures that websites adapt and look good on various screen sizes, from desktops to smartphones.

Network Protocols KS4
KS4 Year 10 MS PowerPoint Presentation on Network Protocols, specifically the Application Layer Protocols.
Internet Protocol(Samyak Jain 25014).pptx
The document discusses Internet Protocol (IP) which specifies the format of data packets and the addressing scheme used on networks. IP allows for addressing and dropping packets in the network system like a postal system, but does not directly connect the source and recipient. Most networks combine IP with Transmission Control Protocol (TCP) to establish a connection between hosts to send messages back and forth. Commonly used internet protocols include TCP/IP, FTP, and HTTP. IP addresses provide a unique global address for network interfaces and encode network and host numbers. While IPV4 is currently used, IPV6 is designed to replace it and provide more addresses and functionality for future internet growth.

Protocols of network in computer science
Network protocols are sets of rules that allow computers to communicate over a network. TCP/IP is a widely used set of protocols that power the internet. TCP/IP was developed in the 1970s-80s and includes protocols like TCP, IP, HTTP, and FTP. Network protocols define data formats, error handling, routing, and other aspects of network communication to ensure reliable data transmission between devices. Common protocols serve functions like file transfer, email delivery, and network management. Protocols provide benefits like increased connectivity and speed for data transmission.
Internet protocol
1. The Internet Protocol (IP) is responsible for addressing hosts and routing packets across networks to allow communication between devices.
2. There are two main versions of IP - IPv4 uses 32-bit addresses and IPv6 uses 128-bit addresses to allow for more devices as the number connected to the internet grows exponentially.
3. TCP and UDP are protocols that operate at a higher layer than IP and provide different functions - TCP enables reliable transmission of data through sequencing and acknowledgment while UDP provides a basic transmission model without these features.

Presentation (1)
Modems convert digital signals to analog signals for transmission over phone lines and vice versa. They are classified by connection type and transmission mode. Functions include data compression, error correction, and flow control. TCP/IP is the standard communication protocol for the Internet and networks. It has application, transport, internet, and link layers. The World Wide Web is a system of interlinked hypertext documents accessed via the Internet using browsers. It allows information sharing through URLs and hyperlinks.
07 - TCP_IP and the DoD Model.ppt
This document provides an overview of the TCP/IP model created by the Department of Defense (DoD) and compares it to the OSI reference model. The DoD model consists of four layers - Process/Application, Host-to-Host, Internet, and Network Access - which correspond to a condensed version of the seven-layer OSI model. The document describes the functions of each layer and some of the key protocols that operate at each layer, such as TCP, IP, ARP, and Ethernet. It also covers topics like IP addressing, private vs public addresses, broadcast vs unicast traffic, and network access technologies.
How does the internet work
The document discusses the key components and protocols that make up the internet. It explains that hardware components like routers, servers, and transmission lines physically connect devices, while protocols like TCP, IP, HTTP allow them to communicate and transfer data. It describes how a browser uses the URL to locate a server via its IP address with help from DNS servers, then loads a webpage by sending HTTP requests and receiving the HTML file from the server.
TCP/IP Modal
The document discusses TCP/IP (Transmission Control Protocol/Internet Protocol), which is a suite of communication protocols used to connect devices on the internet and private networks. It describes the history of TCP/IP's development by DARPA in the 1970s and its use in Unix operating systems. The document outlines the importance, uses, layers, and basic functioning of TCP/IP.
Internet
The internet began in the 1960s as a project of the U.S. Department of Defense to link government and university computers. It has since grown to connect millions of computers worldwide through various connection types like dial-up, broadband, cable and DSL. The internet allows people to communicate via email and chat, access information through websites, and share files using protocols like HTTP, FTP and SMTP. Every device on the internet has a unique IP address or domain name and security risks exist like password sniffing, spoofing and spam.
Comparison of DOD and OSI Model in the Internet Communication
The Internet protocol suite is the computer networking model and set of communications protocols used on the Internet and similar computer networks. It is commonly known as TCP IP, because it's most important protocols, the Transmission Control Protocol TCP and the Internet Protocol IP , were the first networking protocols defined in this standard. Often also called the Internet model, it was originally also known as the DoD model, because the development of the networking model was funded by DARPA, an agency of the United States Department of Defense. TCP IP provides end to end connectivity specifying how data should be packetized, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved. From lowest to highest, the layers are the link layer, containing communication technologies for a single network segment link the internet layer, connecting hosts across independent networks, thus establishing internetworking the transport layer handling host to host communication and the application layer, which provides process to process application data exchange. Our aim is describe operation and models of TCP IP suite in data communication networking.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
