CAS stands for “CSIT Active Society” CAS is a small private group which was created for group

learning or doing group project but hearing demand of other people CAS decided to be public and fulfill all demands that have been lacked by OSAC we are somewhat like brothers OSAC group so we decided to train people from the base.

It indicates the unity among every CSIT team in every college in IT field

Our motto is to teach and learn together from base to the top regarding any new technology and to make every IT student skilled as they should be being IT student and to unleash the technological potential of the student.

Our slogan we believe in doing practically rather then wasting time in discussing

CAS is a social group for all the beginner, intermediate and expert people.

TO LEARN FROM BASE IT IS SMALL GROUP WHICH INSPIRES EVERYONE TO LEARN

TOGETHER AND SHARE TOGETHER CAS IS A GROUP OF PEOPLE WHO MUST BE EQUALLY

TRAINNED N WILL BECOME EXPERT IN WHAT THEY DO. CAS WILL NOT CHANGE ITS TOPIC EVERY DAY THEY WILL BE

TRAINNED FROME BASE TO TOP NO MATTER HOW MANY DAYS IT TAKES.

CAS HAVE BIG PLANS FOR FUTURE WITH ITS MEMBER. IT DOES NOT ONLY TRAIN ASCOL PEOPLE, IT WILL ALSO TRAIN OTHER COLLEGES WHEN TIME COMES. THIS GROUP IS FORMED TO DO BIG PROJECT FOR CAS WHEN AS MANY MEMBER ARE WELL TRAINED.

CAS DON'T BELIEVE IN SINGLE PERSON LEADERSHIP IT ALWAYS BELIEVE IN GROUP DECISION FOR ITS GOOD.

CAS BELIEVE IN DOING THINGS PRACTICALLY RATHER THEN WASTING TIME IN DISCUSSION.

CAS PROVIDES BETTER OPPORTUNITIES FOR THOSE PEOPLE WHO ARE WELL SKILLED AND READY TO BE KEPT IN FIELD.

CAS BELIEVES IN UNITING ALL THOSE MEMBER WHO THINKS THAT THEY ARE NOT GOOD IN TECHNOLOGICAL FIELD AND DOES NOT ATTEMPT ANY PRESENTATION . E.G WE HAVE 60 STUDENT IN OUR CLASS AND 40 STUDENT IN 4TH SEMESTER AND MANY MORE IN OTHER SEMESTER BUT WHEN WE ATTEMPT ANY PRESENTATION WHERE ARE THOSE MEMBER????

CAS IS A NEW HOPE FOR THOSE PEOPLE WHO THINKS THEY HAVE ALREADY BEEN LEFT BEHIND IN CASE OF KNOWLEDGE.

HEALTHY COMPETITION

WE DON’T BELIEVE IN DOMINATING ANY GROUP OR ORGANISATION IF SOME ORGANISATION FEELS SO THEN LETS HAVE HEALTHY COMPETITION IN LEARNING AND PRESENTING PROCESS WHICH WILL HELP BOTH THE GROUPS AND BOTH GROUPS MEMBER.

THE CAS MEMBER NEVER SHOULD HASITATE IN SAYING WE ARE OSACIAN AS WELL. WE ARE FIGHTING FOR KNOWLEDGE. WE WILL VISIT AND SUPPORT EVERY ORGANISATION AND GROUPS WHICH WILL PROVIDE GOOD KNOWLEDGE SO WE SUPPORT OSAC FOR WHAT THEY ARE NOW. EVERY MEMBER OF CAS SHOULD ATTEMPT EVERY PRESENTATION OF OSAC AND OSAC GROUP IS EQUALLY INVITED IN OUR PRESENTATION.

CAS WILL NEVER ACCEPT THE WAR FOR GROUP, IT WILL ALWAYS ACCEPT THE WAR FOR KNOWLEDGE.

History of Operating System(OS)

What is OS and its Importance

X86(32-bit) and X64(64-bit) OS

Some Tricks

DOS

Windows 3.1

Windows 95

Windows 98

Windows 2000 Windows 2000 server

Windows xp Windows 2003 server

Windows vista

Windows 7 Windows 2008 server

Windows 8 Windows 8(2012) server

Windows Operating System needs money whereas there

are many other OS which is free i.e. we can simply

download the OS from the internet and install it in our

Computer System. E.g.

Unix

Linux

Ubuntu

Obuntu (Customized by our Osac Group)

Mac

Before, In Linux OS, to do anything we need to program

i.e. it was command based OS but now it has also

modified to GUI mode for creating better User Friendly

Environment.

Operating system is simply a very complex computer program yet

most important program in a computer system.

It acts as a interface between the user and the computer hardware.

It provides the operational environment to the users and the

application program.

The language that user uses is different from that of the hardware

as user prefers natural language or near natural language for

interaction whereas the hardware uses machine language.

It is the OS that does the necessary translation back and forth and

lets the user interact with the hardware.

Without OS, hardware of a computer system is just an inactive

electronic machine, possessing great power, but doing nothing for

the user.

32-bit OS means that 32 bit of data is transferred at a time

and same goes for 64-bit OS.

The Programs that are supported by 32-bit OS may not be

supported by 64-bit OS. E.g. device drivers of 32-bit OS

does not run in 64-bit OS.

Incase of 64-bit OS, programs that are made to run in 64-bit

OS does not run in 32-bit OS.
