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.

This document discusses common network protocols and their functions. It explains what network protocols are and why they are important for enabling communication across the internet. It then provides descriptions of 12 common network protocols (ARP, BGP, DNS, DHCP, FTP, HTTP, IP, OSPF, SMTP, TCP, UDP, Telnet) and explains their basic functions and purposes. It also mentions some additional related protocols.
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).
TCP - TCP breaks data into manageable packets and tracks information.pdfanjanacottonmills
TCP - TCP breaks data into manageable packets and tracks information such as source and
destination of packets. It is able to reroute packets and is responsible for guaranteed delivery of
the data.
IP - This is a connectionless protocol, which means that a session is not created before sending
data. IP is responsible for addressing and routing of packets between computers. It does not
guarantee delivery and does not give acknowledgement of packets that are lost or sent out of
order as this is the responsibility of higher layer protocols such as TCP.
UDP - A connectionless, datagram service that provides an unreliable, best-effort delivery.
ICMP - Internet Control Message Protocol enables systems on a TCP/IP network to share status
and error information such as with the use of PING and TRACERT utilities.
SMTP - Used to reliably send and receive mail over the Internet.
FTP - File transfer protocol is used for transferring files between remote systems. Must resolve
host name to IP address to establish communication. It is connection oriented (i.e. verifies that
packets reach destination).
TFTP - Same as FTP but not connection oriented.
ARP - provides IP-address to MAC address resolution for IP packets. A MAC address is your
computer\'s unique hardware number and appears in the form 00-A0-F1-27-64-E1 (for example).
Each computer stores an ARP cache of other computers ARP-IP combinations.
POP3 - Post Office Protocol. A POP3 mail server holds mail until the workstation is ready to
receive it.
IMAP - Like POP3, Internet Message Access Protocol is a standard protocol for accessing e-
mail from your local server. IMAP (the latest version is IMAP4) is a client/server protocol in
which e-mail is received and held for you by your Internet server.
TELNET - Provides a virtual terminal or remote login across the network that is connection-
based. The remote server must be running a Telnet service for clients to connect.
HTTP - The Hypertext Transfer Protocol is the set of rules for exchanging files (text, graphic
images, sound, video, and other multimedia files) on the World Wide Web. It is the protocol
controlling the transfer and addressing of HTTP requests and responses.
HTTPS - Signifies that a web page is using the Secure Sockets Layer (SSL) protocol and is
providing a secure connection. This is used for secure internet business transactions.
NTP - Network Time Protocol is a protocol that is used to synchronize computer clock times in
a network of computers.
SNMP - Stands for Simple Network Management Protocol and is used for monitoring and status
information on a network. SNMP can be used to monitor any device that is SNMP capable and
this can include computers, printers, routers, servers, gateways and many more using agents on
the target systems. The agents report information back to the management systems by the use of
“traps” which capture snapshot data of the system. This trap information could be system errors,
resource information, or other info.
Protocols define the rules and format for how computers exchange information over a network. The key features of protocols include syntax, semantics, and timing. There are two main protocol models - the TCP/IP model and OSI reference model. TCP/IP is comprised of four layers including network access, internet, host-to-host transport, and application layers. The OSI model has seven layers and provides a framework for developing networking standards. Common protocols like TCP, IP, UDP, HTTP, FTP and SMTP control how different aspects of networking like file transfers, email, and web browsing function.
The document summarizes several key networking protocols. It begins with an overview of protocols in general and the two main protocol models: TCP/IP and OSI. It then describes some of the most widely used protocols for various functions: SNMP for network management, HTTP and HTTPS for web communication, DNS for domain name resolution, DHCP for dynamic IP address assignment, SMTP for email transmission, FTP for file transfer, TCP and UDP for transport layer functions, IP for network layer packet delivery, and ICMP for reporting network errors. The document provides details on the purpose and basic operation of each protocol.

It also defines MAC addresses.
The document provides an introduction to TCP/IP networking and the Internet. It explains that the Internet is a global network of interconnected computers that allows users to access documents, images, videos, and more from anywhere in the world. It describes how the Internet works using TCP/IP, which breaks files into packets that are routed through networks and reassembled at their destination. The document contrasts TCP, which provides reliable connections, and UDP, which sends independent data packets without guarantees of delivery.
Lesson4.9 d u4l3 hierarchy of open protocolsLexume1
This document explains the hierarchy of protocols that manages the complexity of the internet. It discusses how there are multiple layers of abstraction, with the highest being the application layer which turns binary into visible content through protocols like HTTP and DNS. Lower layers include the transport layer which manages packet transmission through protocols like TCP and UDP, the internet layer which handles routing through IP addresses, and the link layer which connects hardware through technologies like Ethernet and WiFi. The use of open standards across these layers allows for widespread interoperability between different devices and networks on the internet.
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.

This document provides an overview of key components of networking infrastructure:
- IP (Internet Protocol) is the standard that governs how devices connect to networks and the internet and includes assigning each device an IP address.
- TCP (Transmission Control Protocol) works with IP to ensure reliable transmission of data packets across networks.
- HTTP (Hypertext Transfer Protocol) is the foundation of the World Wide Web and is used to load web pages.
- HTML (Hypertext Markup Language) is the code that web developers use to structure and present content on websites.
Protocols are sets of rules that allow computing devices to communicate. They define data formats, flow control, routing, error handling and other aspects of communication. Some key protocols include TCP, HTTP, FTP, SMTP, UDP and ICMP. Protocols ensure smooth functioning between systems by establishing predetermined understandings for data transmission, addressing, and error handling. The TCP/IP protocol suite defines widely used standards for exchanging packets of information between computers over networks.
The document discusses several internet protocols including the Internet Protocol (IP) which defines how data is sent between computers, Ethernet which describes how networked devices can format and transmit data on the same network, and Transmission Control Protocol (TCP) which establishes and maintains network conversations for exchanging data between application programs. It also summarizes the Domain Name System (DNS) which maps domain names to IP addresses, User Datagram Protocol (UDP) which is used to establish low latency connections, File Transfer Protocol (FTP) for transferring files between client and server, and Dynamic Host Configuration Protocol (DHCP) which automatically provides hosts with IP addresses and configuration information.
IP resides at the network layer of the OSI model and provides logical addressing that allows systems on different logical networks to communicate. IP packets contain source and destination addresses as well as other fields. Transport protocols like UDP and TCP run on top of IP, with UDP being connectionless and used for real-time voice traffic in VoIP due to its simplicity and lower latency compared to TCP, which provides reliability but higher latency through mechanisms like acknowledgments and retransmissions. RTP runs on top of UDP to provide additional timestamping and sequencing information important for applications like voice calling.

Machining is a material removal process that uses sharp cutting tools to shape a workpiece. The three main machining processes are turning, drilling, and milling. Turning is done on a lathe and involves a single-point cutting tool removing material from a rotating workpiece to create cylindrical shapes. Drilling uses a rotating multi-point tool to create round holes. Milling employs a rotating cutting tool with multiple edges that is moved across the workpiece to cut planes and straight surfaces. Other important topics covered include cutting conditions, tooling, chip formation, forces, and temperatures in machining as well as different lathe and machine operations.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
An improved modulation technique suitable for a three level flying capacitor ...IJECEIAES
This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.

Internet protocols and smart devices for better living.pptx
1. What are - Internet Protocols, a long list of Protocols
Internet Protocols are like a set of rules that devices use to communicate with each
other over the internet. Just like how people follow certain rules when having a
conversation, devices follow these protocols to ensure they understand each other and
can exchange information smoothly.
Here's a list of some common Internet Protocols and what they do:
1.Internet Protocol (IP): This is the main protocol that gives devices unique addresses
so they can find each other on the internet. It's like the postal system we talked about
earlier.
2.Transmission Control Protocol (TCP): TCP helps to break down the data sent over
the internet into smaller packets and ensures they arrive in the correct order. It's like
making sure all the pieces of a puzzle arrive and fit together perfectly.
3.User Datagram Protocol (UDP): UDP is similar to TCP but it's faster and doesn't
guarantee that all packets will arrive or be in order. It's commonly used for things like
live video streaming where a slight delay is acceptable.
4.Hypertext Transfer Protocol (HTTP): HTTP is the protocol used for transferring web
pages from servers to your web browser. When you type a web address into your
browser, it uses HTTP to request the page from the server.
5.Hypertext Transfer Protocol Secure (HTTPS): This is a more secure version of
HTTP. It encrypts the data sent between your browser and the server, making it harder
for hackers to intercept and read.
2. Internet Protocols, a long list of Protocols
6. File Transfer Protocol (FTP): FTP is used for transferring files between
computers on a network. It's commonly used by web developers to upload files
to a website's server.
7. Simple Mail Transfer Protocol (SMTP): SMTP is used for sending email
messages between servers. When you hit "send" on an email, your email client
uses SMTP to send the message to the recipient's email server.
8. Post Office Protocol (POP): POP is used by email clients to retrieve
messages from an email server. It allows you to download your emails onto your
device so you can read them offline.
9. Internet Message Access Protocol (IMAP): Similar to POP, IMAP is used by
email clients to access messages on an email server. However, unlike POP, it
allows you to keep your messages stored on the server so you can access them
from multiple devices.
These are just a few examples of the many Internet Protocols that make the
internet work! Each one plays a specific role in ensuring that data is
transmitted efficiently and securely across the vast network of the internet.
3. What are - Internet Protocols, a long list of Protocols
10.Domain Name System (DNS): DNS translates human-readable domain names (like
google.com) into IP addresses that computers can understand. It's like a phonebook for
the internet, helping your browser find the correct web server when you enter a website
address.
11.Dynamic Host Configuration Protocol (DHCP): DHCP automatically assigns IP
addresses to devices on a network when they connect. It's like a host at a party handing
out name tags to guests as they arrive, ensuring everyone gets a unique identifier
without conflicts.
12.Internet Control Message Protocol (ICMP): ICMP is used for diagnostics and error
reporting in network communication. It helps devices communicate status and
troubleshoot issues, like when a server is unreachable.
13.Border Gateway Protocol (BGP): BGP is used by internet routers to exchange
routing information and make decisions on how to forward data between autonomous
systems (like internet service providers). It's like a network of road signs directing traffic
on the internet's highways.
14.Simple Network Management Protocol (SNMP): SNMP allows network
administrators to monitor and manage network devices remotely. It provides a
standardized way to collect information about devices and detect and resolve issues.
15.Internet Protocol Security (IPsec): IPsec provides security features for IP packets,
such as encryption and authentication, to protect data as it travels over the internet. It's
like putting your data in a secure envelope with a lock and key before sending it out.
4. What are - Internet Protocols, a long list of Protocols
16. File Transfer Protocol Secure (FTPS): FTPS is a secure version of FTP
that adds encryption to protect file transfers from eavesdropping and
unauthorized access.
17. Secure Shell (SSH): SSH provides secure remote access to computers and
servers over an unsecured network. It encrypts the communication between the
client and server, preventing eavesdropping and tampering.
18. Simple Object Access Protocol (SOAP): SOAP is a protocol for
exchanging structured information in web services. It defines how messages are
formatted and transmitted between applications over the internet.
19. WebSocket: WebSocket is a communication protocol that provides full-
duplex communication channels over a single TCP connection. It's commonly
used for real-time web applications, like chat and gaming, where low latency and
high throughput are crucial.
These protocols, among many others, work together to make the internet a
functional and reliable global network, enabling communication, data exchange,
and collaboration on an unprecedented scale.

long list of Protocols
20.Simple Network Time Protocol (SNTP): SNTP is used to synchronize the
clocks of devices on a network to a coordinated universal time reference. It
ensures that all devices have accurate timestamps for events, which is crucial for
tasks like logging and coordination across distributed systems.
21.Trivial File Transfer Protocol (TFTP): TFTP is a simplified version of FTP
used primarily for transferring files between devices in a local network. It's
lightweight and doesn't require user authentication, making it suitable for tasks
like updating firmware on network devices.
22.Voice over Internet Protocol (VoIP): VoIP enables voice communication
over the internet by converting analog voice signals into digital data packets.
Services like Skype and Zoom use VoIP to facilitate voice and video calls,
offering cost-effective and flexible communication options.
23. Session Initiation Protocol (SIP): SIP is a signaling protocol used for
initiating, maintaining, and terminating multimedia sessions, including voice and
video calls over IP networks. It's widely used in VoIP systems and other real-time
communication applications.
6. Internet Protocols, contd…
20.Real-time Transport Protocol (RTP): RTP is used in conjunction with SIP for
delivering audio and video streams over IP networks. It provides mechanisms for
packetization, timestamping, and delivery monitoring, ensuring smooth and
synchronized media playback.
21.Internet Group Management Protocol (IGMP): IGMP is used by multicast routers
to manage membership in multicast groups on a network. It enables hosts to join and
leave multicast groups dynamically, facilitating efficient distribution of multimedia content
to multiple recipients.
22.Simple Mail Transfer Protocol Secure (SMTPS): SMTPS is a secure version of
SMTP that adds encryption to protect email communication between clients and
servers. It uses SSL or TLS to encrypt the data transmitted over the network,
safeguarding sensitive information from interception.
23.Network Time Protocol (NTP): NTP is an updated and more robust version of
SNTP, used for synchronizing the clocks of devices on a network. It employs more
sophisticated algorithms and mechanisms for clock adjustment, offering higher accuracy
and reliability.
7. What are - Internet Protocols, a long list of Protocols
24. Internet Control Protocol (ICP): ICP is a caching protocol used in web proxy servers
to improve performance by storing and serving frequently accessed web content locally.
It reduces latency and bandwidth usage by retrieving content from the cache instead of
fetching it from the origin server every time.
25. Border Gateway Protocol 4 (BGP-4): BGP-4 is an enhanced version of BGP used in
large-scale networks, such as the internet backbone. It includes features for route
aggregation, policy-based routing, and traffic engineering, enabling efficient and flexible
management of network traffic flows.
These protocols, with their specific functions and capabilities, form the foundation of
the modern internet, enabling a wide range of applications and services that we rely on
every day.
