MEMRISTOR-The 4th fundamental circuit Element.


We all know that there are only 3 fundamental circuit elements capacitor,resistor and the inductor.but there is also a new circuit element discovered called the memristor.Firsty i would tell u wat is the functioning iof the memristor.The Memristor is the contraction of Memory Resistor because that is exactly its function.It remembers the past.
Coming to the uses it is predicted that the memristor when combined wid transistors can help in the construction a new circuits which function like our brain.
A memristor is a 2 terminal device whose resistence depends on the magnitude and the polarity of the voltage applied to it and length of time that voltage is applied.when we turn off the voltage the memristor remembers its most recent resistence until the next time it is turned on,whether that happens a day later or a year later.
I think by reading this you have already gussed that memristor can be used in the field of computers . think about it. i will give u the answer in my next post .
Happy NEW YEAR 2009

Car Talk


Enough of computer stuff!!let us talk some thing bout some fun....
jst imagine ur car while driving on the road talking with other cars in order to drive safely!!!
is it not wonderful?This idea is being worked upon by the scientists of Europe...
the basic mechanism is this...when a car moves on the road it creats a connectionless  connection i.e a UDP connection is established ....and then it goes on sending packets to the cars around a give range.u might be wondering how the ip adddress of one car is known to other...dont worrry about that...the technique that is likely to be used is "Flooding" and so the packets are just sent... to all cars in the range..... and this the way in which the cars talk.. on the roads....after reading this article in the ieee magazine i just got another idea... why cant we store data in air?? think on this and if u have any way of doin it  let mw know

Wireshark


Ah,finally i speak abot a topic of my fav subject networks......
wireshark is a tool which helps in capturing packets that flow to and from ur computer to the network and also if correct packet filter is selected it can also capture packets from other routers..... 
so my basic aim is to give a detailed discussion of wireshark and its uses.....u can see the packets that u sent to ur friend in yahoo messenger while chatting.. and also track his/her                                     ip address....and one more thing wireshark with ip tracking tools becomes a very powerful tool to hack.. many other things......so have u need to have a profound knowledge of wire sharkto become a network administrator.... .. more coming up with screen shots in my nxt post......

CYGWIN

My first post contains info 'bout cygwin which is a collection of unix tools for windows operating system.For example u don't want to run linux(unix)operating systems but still want to use tools such as "vi editor" for writing and executing ur unix programs use cygwin.Its that sipmple!!!! 
for downloadin cygwin jst check this link.
I will be updating more information on how to use cygwin.
But i will request u to move slowly from windows to linux operating system
