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.

If you want to know error detection techniques then this video will solve your query.

This is a part of lecture presented by Ms.Rashmi Sharma Asst. Professor of Biyani Girls College. The video is about Stack Data Structure. Stack data structure is one of the most useful concepts in computer science. Stack is a data storage structure (Abstract data type). Unlike, arrays access of elements in a stack is restricted. It has two basic operations push and pop for insertion of an element and deletion of an element. The video is helpful for BCA, MCA, and M.Sc. (IT) Students.
