A8-R4 : BASICS OF OS, UNIX AND SHELL PROGRAMMING Syllabus

Objective of the Course

The objective of the course is to make students aware of the functioning of a multi-user operating

system. This course will serve as a foundation course for the higher level course in Unix. The
students are expected to learn the commands while doing practical and emphasis should be
given to those switches/options and flags, which are most frequently used in real life.

After completion of the course students will be able to:

   • Understand Operating System concepts.
   • Use System calls and memory management.
   • Use Unix commands and editors.
   • Carry out Unix File management and shell programming in Unix.
   • Do Network configuration and security management in Unix.

Save Image In Access and Retrieve in Datagridview Using VB.net

This small project will help you to understand how can you handle image processing in your VB.net Window Application. There are many times when we want to save images in our project software for instance  in school software Saving student image. So you can achieved this through following approach

1. Saving Image into database
2. Saving image into a folder

First approach is not so much popular because image get more size than normal data  So your database saved thousands of byte for an image which lead decline in record retrieval. if you want to follow this approach click on Following Link

Save Image into MS Access  database

This post deal with second approach because its good practice to save information into database and image in a folder . you can save image name into database or rename uploaded image as your table  ID (PK) field value. I am saving image name into database which is easy to implement but renaming image is more suitable because its decrease  database storage.

Dennis Ritchie Computer Scientist

Dennis was an American computer scientist. He created the C programming language and, his colleague Ken Thompson, the Unix operating system. Ritchie and Thompson received the Turing Award from the ACM in 1983, the Hamming Medal from the IEEE in 1990 and the National Medal of Technology from President Clinton in 1999. Ritchie was the head of Lucent Technologies System

Martin Richards (computer scientist)

Martin Richards (born 21 July 1940) is a British computer scientist known for his development of the BCPL programming language which is both part of early research into portable software, and the ancestor of the B programming language invented by Ken Thompson in early versions of Unix and which Dennis Ritchie in turn used as the basis of his widely used C programming language.
