Selective Repeat is part of the automatic repeat-request (ARQ). With selective repeat, the sender sends a number of frames specified by a window size even without the need to wait for individual ACK from the receiver as in Go-Back-N ARQ. The receiver may selectively reject a single frame, which may be retransmitted alone; this contrasts with other forms of ARQ, which must send every frame from that point again. The receiver accepts out-of-order frames and buffers them. The sender individually retransmits frames that have timed out. ....etc

Introduction
With online business more important now than in yesteryears, importance of securing
data present on the systems accessible from the Internet is also increasing. If a
system is compromised for even a small time, it could lead to huge losses to the organization.
Everyday new tools and techiniques are devised to stop these malicious
attempts to access or corrupt data.
Traditionally firewall have been used to stop the intrusion attempts by an
attacker. But firewalls have static configurations that bloc ....etc

TCP Connection Termination
each side terminates its end of the connection by sending a special message with the FIN (finish) bit set.This bit serves as a connection termination request to the other device. Both the sides have to finished the shut down procedure to end the connection completely. Thus connection termination is is a pair of two-way handshakes. . the TCP on the device receiving the initial termination request must inform its application process and wait for a signal that the process is ready to proceed.

Comparison and Contrast between the OSI and TCP/IP Model



Introduction

This presentation would discuss some comparison and contrast between the 2 main reference models which uses the concept of protocol layering.

Open System Interconnection Model (OSI)
Transport Control Protocol /Internet Protocol (TCP/IP)

The Session Layer

The Session layer permits two parties to hold ongoing communications called a session across a network.

In any analysis of innovation, 802.11 is truly a prime number. This evolving standard, better known as Wi-Fi, is the it protocol that s won the same spectacular hype as (whisper it softly) the Internet itself. Oh, the good old days. I miss them.

But while Wi-Fi undeniably inspires that intoxicating blend of expectation and excitement that leads to entrepreneurial excess, it s also the kind of technological platform that invites the best ideas. Wi-Fi s combination of well-crafted technical standard and regulation-free deployment offers a ....etc
