TCP Port Service Multiplexer (TCPMUX) allows contacting any one of several available TCP services on a single port. Remote Job Entry (RJE) sends processing job requests to mainframe computers from remote workstations. Simple Mail Transfer Protocol (SMTP) establishes electronic mail (email) transmission over port 25. Domain Name System (DNS) is a hierarchical distributed naming system that resolves domain names to IP addresses using port 53.
Overview of the TELNET protocol.
TELNET is a protocol providing platform independent, bi-directional byte-oriented communication between hosts (unlike rlogin which is Unix based).
Most often TELNET is used for remote login to hosts on the Internet.
TELNET is basically a TCP connection with interspersed TELNET control information.
TELNET may use option negotiation for providing additional services such as character echoing back to the sender.
TELNET does not provide any authentication and therefore should not be used in unsecure environments anymore. SSH (Secure SHell) should be used instead.
This presentation outlines the core functions of TCP - Transmission Control Protocol.
These comprise TCP Connection Control, TCP Flow Control, TCP Error Control, TCP Congestion Control, TCP Options and TCP Timers.
TCP/IP is the Internet core protocol that provides reliable, connection-oriented and stream-based communication service. Most of Internet traffic is carried in TCP connections, so scalability and reliability are crucial for a stable network on a global scale.

ISBR's students took part in HR Showcase 2015 , a mega event organised by NHRD, Bangalore at White Feather on 11th September. Here students got the opportunity to interact with few of the best coporates in the industry. They benefitted by some of the eminent speakers from the industry who mentioned the emerging HR technologies and practices to shape the future business and society. It was a great learning experience for students soon to be employed.
This tutorial gives very good understanding on Computer Networks protocols After completing this tutorial, You will find yourself at a moderate level of expertise in knowing Advance Networking protocols (, from where you can take yourself to next levels.
Transport Layer Port or TCP/IP & UDP PortNetwax Lab
A port is an application-specific or process-specific software construct serving as a communications
endpoint in a computer's host operating system. The purpose of ports is to uniquely identify different
applications or processes running on a single computer and thereby enable them to share a single
physical connection to a packet-switched network like the Internet. In the context of the Internet
Protocol, a port is associated with an IP address of the host, as well as the type of protocol used for
communication.

Discuss the purpose of subnetting. What does CIDR stand for and mean?
Discuss the use of ARP, TCP, UDP, FTP, HTTP, and Telnet.
How does TCP ensure reliable delivery? Name a few TCP protocols. What is TCP's "counterpart" that does not ensure reliable delivery? Name a few of these protocols.
Discuss the purpose of subnetting.
In a subnet, the hosts may be on different physical networks but share a single network number. Each host in the subnet is configured with an IP address and Subnet mask.
Discuss the use of ARP, TCP, UDP, FTP, HTTP, and Telnet.
The Application layer consists of protocols that focus on process-to-process communication across an IP network and provides a firm communication interface and end-user services. These services are sub protocols with specific goals.
ARP (Address Resolution Protocol) is responsible for resolving internet addresses into link layer addresses. It is also used for mapping a network address to a physical address.
TCP (Transmission Control Protocol) is connection-oriented, reliable communications service responsible for the establishment of a TCP connection, the sequencing and acknowledgement of packets sent, and the recovery of packets lost during transmission.
UDP (User Datagram Protocol) is used when the amount of data to be transferred is small, or when the applications or upper layer protocols provide reliable delivery.
FTP (File Transfer Protocol) allows files to be transferred between computers
HTTP (Hypertext Transfer Protocol) is used to transfer web pages to end-users.
Telnet is a bi-directional text communication via a terminal application; it’s used for logging on remotely to network hosts.
How does TCP ensure reliable delivery?
The TCP provides reliable communications services by providing sequencing services to the packets sent as well as an acknowledgment service. When the correct response is not received, TCP process the packet again to assure the requested transfer happens.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

A Strategic Approach: GenAI in EducationPeter Windle
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.
