About Sim card

Now a days many sim cards avaiable in market . But so many doesn't know ABBREVATION of SIM card and how it operates. SIM->SUBSCRIBER IDENTITY MODULE. it works as follows...When the Mobile starts up, it obtains the IMSI from the SIM card, and passes this to the mobile operator requesting access and authentication. The Mobile Equipment may have to pass a PIN to the SIM card before the SIM card will reveal this information.The operator network searches its database for the incoming IMSI and its associated Ki. The operator network then generates a Random Number (RAND) and signs it with the Ki associated with the IMSI (and stored on the SIM card), computing another number known as Signed Response (SRES_1). The operator network then sends the RAND to the Mobile Equipment, which passes it to the SIM card. The SIM card signs it with its Ki, producing SRES_2 which it gives to the Mobile Equipment along with encryption key Kc. The Mobile Equipment passes SRES_2 on to the operator network.The operator network then compares its computed SRES_1 with the computed SRES_2 that the Mobile Equipment returned. If the two numbers match the SIM is authenticated and the Mobile Equipment is granted access to the operator's network. Kc is used to encrypt all further communications between the Mobile Equipment and the network. IN THIS WAY SIM CARD WILL BE ACTIVATED.

C-language

The basic language to learn for an engineer. And for computer students it is a simple language when they interact with more object oriented languages. C is an structured oriented language. Which was developed by Dennis ritchie in 1972. This is the first statement we will learn when we say about C. We should reveal the secrets of c to learn more about it.

btech Completed

when i am leaving the college at last exam i feel sad and i dont know what happening. when i thought, me and my friends cant meet again and enjoy the days i cant bare . Excellent life in college. we spended very happily and we make lot of rubbish things. when we retrospect the things every one will get tears ... Hats off to college days..

Exams

In b-tech life i was bored with exams.. studying subjects, remembering and again revealing them in the exam hall became daily habit for us.. i got bored with them and cant gain good marks. A exam should have a theoretical parallel y practical then only we can assess the student.. the most better thing is objective questions.

operating system

The excellent software which will manage different softwares and provide interaction to the user.this may be different definition but if we watch the OS the whole work done by it is to manage the softwares and provide output. not only softwares it also manage memory for efficient work. and different resources.. when computer reboots first of all processor takes the control and makes runs its files and initializes boot strap loader to run which in turn runs the operating system and makes the other software to work.

songs

I prefer melodious songs, and instrumental songs.... in melodious songs also i like the songs which give meaning full lyrics.. and which touches my heart. favorite songs MANCHI MANASULU ---> "jabili kosam akasamale vechanu ne raka ki " i like very much so much of meaning is there in that song.. next "swathi mutyapu jalulalo..... "(no idea about title).. Arya-->"EDHO priya ragam"... and more.......

favourite game

In video games i like CONTRA because it is the first game i played . it was a adventure game . next i like tekken . It is a play station game. my favorite worrier YOSHIMITSU . i will play many games but no game gave much satisfaction as above games. After wards my second vote to Mario in video games. which was also little bit adventure game. coming to computer games i like races. favorite race game is NFS.

Best moments in engg

my best moments are when i entered in to engineering college for the first time, when my batch performed a skit on engineers day in 2-1. when i fail for the first time in first year and when i score highest marks in that failed subject, vi zag tour with my friends for the first time, when i cried a lot for some one, when i created my first date program, when i got selected in wipro and again failed to get selected at the time of reassessment. when i failed to select in accenture , and selected in ACCORD which was memorable moment and great success to me.

materials for different languages

The best ever site i have ever seen for different types of computer languages materials and to learn different computer language softwares is Click here to view . i like that site very much.. it contains lot of information. it contains materials to provide brief description for languages.

Books

i don't like book reading . i know its a good habit but i cant sit for a half an hour and read the book. i like practical proving . Most of the books have theoretical explanation but when we observe them practically it is very much easy to remember and we can place more attention to that book.. i am saying about subject books.. but coming to novels and magazines ..oops... i cant ... up to know i didn't read a book completely not even half ...this is my opinion about books.......
