Network Allocation Vector How do other stations defer sending their data if one station acquires access? In other words, how is the collision avoidance aspect of this protocol accomplished ? The key is a feature called NAV. When a station sends an RTS frame, it includes the duration of time that it needs to occupy the channel. The stations that are affected by this transmission create a timer called a network allocation vector (NAV) that shows how much time must pass before these stations are allowed to check the channel for idleness. Each time a station accesses the system and sends an RTS frame, other stations start their NAV. In other words, each station, before sensing the PHYSICAL MEDIUM to see if it is idle, first checks its NAV to see if it has expired.
Collision During Handshaking What happens if there is collision during the time when RTS or CTS control frames are in transition, often called the handshaking period? Two or more stations may try to send RTS frames at the same time. These control frames may collide. However, because there is no mechanism for collision detection, the sender assumes there has been a collision if it has not received a CTS frame from the receiver. The back-off strategy is employed, and the sender tries again.
There are4 octets in an IP address as shown below:Octet1.Octet2.Octet3.Octet4Every IP class has different allocation of network and host ID.For class A, the network and host IDs' allocation is as follows:Network.Host.Host.HostFor class B, the network and host IDs' allocation is as follows:Network.Network.Host.HostFor class C, the network and host IDs' allocation is as follows:Network.Network.Network.HostYou may go to the following link get more info on IP address classes and their IDs:www.iphow.x10hosting.com

Distance vector routing is used when the network is simple and has no hierarchical design. Examples of distance vector routing protocols are RIP and IGRP.
Vector marketing includes news, company profile, people, products, and programs. Vector marketing is a very good program and I suggest that you get into it.
The vector's push_back() member inserts one or more new elements at the end -- the back -- of the vector. If there are insufficient unused elements available, the underlying array is reallocated with a larger reserve and the existing elements moved to the new allocation, after which the new elements are appended. All iterators into the vector are rendered invalid after a reallocation.
The techniques include End-system flow control, Network congestion control, Network based congestion avoidance and Resource allocation.
The purpose of vector Java is to make more Java possibilities for mobile and uniformed devices. The makers of Java said that they wanted to "revolutionize" the way that Java works and helps around the globe.
