This is a part of lecture presented by Ms.Rashmi Sharma Asst. professor of biyani girls college.The video is about Queue Data Structure. In queue data structure insertion takes place on rear end and deletion takes place on front end. It is FIFO(first-in-first-out )structure. The video is helpful for BCA, MCA, M.Sc.(IT) Students.

Ms. Shivangi Gupta, B.Tech Student, Biyani Institute Engineering & Technology explained about research work done in JAIST ,Japan on the topic Wireless Sensor Network. www.gurukpo.com, www.biyanicolleges.org

Ms. Pooja Sharma, MCA Student, Biyani Institute of Science and Management explained about research work done in JAIST ,Japan on the topic Software Verification Process by using set solver. www.gurukpo.com, www.biyanicolleges.org

Fibonacci series , 0 , 1 , 1 , 2 , 3 , 5 , 8 , 13 , 21 , 34 ………Fibonacci sequence are the numbers in the following integer sequence 0 , 1 , 1 , 2 , 3 , 5 , 8 , 13 , 21 , 34 ……… By definition, the first two numbers in the Fibonacci sequence are 0 and 1, and each subsequent number is the sum of the previous two.

It is part of lecturer provided by Mrs. Rashmi Sharma, Asst. Prof. in Biyani Group of
colleges on behalf of gurukpo.This lecturer is about RSA algorithm which is more secure cryptographic algorithm. It is more secure Asymmetric key algorithm. It is 70 times more secure then Symmetric key algorithm (e.g. DES)

Process is a program in execution. Process is dynamic and active and it resides in Main memory. Process is a data structure which has attributes as well as process states. Attributes are like process id, state, GPR, program counter, list of open files and devices etc. Process states are: ready, running, block, suspended etc. There are 3 types of schedulers namely: long term (new to ready ), short term(ready to run) and medium term(for swapping)

Compiler is a program which coverts High Level Language (source code) into assembly level language (executable code). Compiler works fast as compared to interpreter. Compiler comprises of following:
1. Lexical Analyzer (Generates Tokens),
2. Syntax analyzer (generates parser),
3. Semantic Analyzer (type checking),
4. Intermediate Code Generation (3-address code),
5.Code Optimization, and 6. Target code generation.

This topic s related with the subject microprocessor & micro controller. 8255 is known as the programmable peripheral interface use to taking extra input & outputs. It is 40 pin IC & have 24 pins for input & output peripheral. It work in various modes that’s simple i/o mode, i/o with hand shaking, bidirectional i/o with handshaking.

This is a part of lecture presented by Ms.Rashmi Sharma Asst. professor of Biyani Girls College. This video is about Selection Sort. This algorithm sorts the data in ascending order. In Selection sort element at position 0 compared with all other element in the array. If the element found greater from other element then interchanged. The video is helpful for BCA, MCA, M.Sc. (IT) Students.
