Jac, life and all that..

i m starting this blog with one old memory of my B.E.

i was in 7th sem. and enjoying some of the last days in my college.
each saturday we have some "extra" work to do besides academics
i was meeting some of my juniors who were in 1st/3rd semester
around 40 dainty students were interested in me.
and i have to explain them how internet/web/html/network/servers works
after some "funda" abt 20-25 mins abt all above,
i asked them to throw questions from thier minds
some questions were silly,some intelligent,some were out of my range also
for exa.
-how to change password in yahoo?
-why cybercafe dont have modem?
-why our college's website is slow?
-how google works?
-why my id is *@yahoo.com and some other's *@yahoo.co.in?
-why mobile internet aceess is limited?

i asnwered some
some bluffed..

but one question was really good..
-how yahoo earns after providing free email to us?
i told it earns through advertisement..
it sells our email id to 3rd party and so on..
then he asked its quite limited advertisement
i said "its true.."

some days ago
i came back to window after 6 month for some wireless scanning s/w
it gave me chance to see pure yahoo..
after so long time

some changes in six month
-better voice conversation
-yahoo avatar..

i went for avatar
cool..
make ur own identity
javascript at work..
lot of scripts..
and lot of options..
cloths,hair,background,skin,accessories and some others also
so questions remains same
how yahoo/any other web-based org earns?
and its one of best employer prefered..after google
huge package in IIT's campus placement..

i will figure it out someday..
atleast after going to some company atleast..
enough for avataar..
chalo
bye

got some time to blog after long time
i completed end sem exam
luckily passed all the courses
and CPI of 7.84/10
not so good in IIT but i m quite happy with it
now in december,
just for our work in timbaktu,
i was measuring signal strength of Access Point and antena attached to it.
it was gr8 learning experience
i was working with real wireless devices first time
and that too, i have to configure/use/debug it.
D-link is famous brand around and we are also using same.

D-link provides web interface for configuring APs
so platform independent
that also means that it is running some web-server kind of utility
nice huh?
it also has its DHCP
and SNMP also
now u got idea ? why APs cost much?

i wud like make to write some important technical aspect of it
APs has some important attributes like:
1. IP
2. MAC
3. datarates(mbps)
4.channel
5.SSID
6.DHCP range
7.connectivity to LAN
8.default gateways and DNS
9.direction of antena
10.range (meter)
11. signal (db)
12.SNR(signal to noise ratio)

i m still finding some difficulty in associating with perticuler SSID and n/w
but its not a problem of AP/D-link
its windows' bug for roaming
but now problem is solved largely as i have centrino based laptop
the previos one was with external WiFi card
and gave lot of trouble to me in my intial work
thats guru mantra of today
its late night now
i must go to canteen for food
otherwise it will be closed also
bye for now
