One of the greatest advantages of using a 64-bit version of Windows is the ability to access physical memory (RAM) that is above the 4-gigabyte (GB) range. This physical memory is not addressable by 32-bit versions .
Depending on the version of Windows that is installed, a 64-bit version of Windows supports from 1 GB of RAM to more than 128 GB of RAM. The ability to address more physical memory lets Windows minimize the time that is required to swap processes in and out of physical memory. Therefore, Windows can manage processes more efficiently. This memory management feature helps improve the overall performance of Windows .

When Amarjeet Sir announced in the class that no one from group 2 had volunteered for leading lab session 5, we rushed to give our names, to get rid of the burden of leading lab session at a later stage.
Like Nishant said that on the day of training when we initially saw the questions we were puzzled but slowly as the lab progressed we started to get the concepts of grep, sed and awk ,and were at a little ease.After the training we understood most of things, but were not confident on how we would be going to teach these things to our peers.
Iniitially we were expected to lead the lab on 24th august, but due to Raksha Bandhan it was postponed till 27,we were happy as we got some extra time to prepare,but lab was postponed again to 31 august,at that time we were really frustrated,we wanted to finish this task as early as possible but it kept on extending.
Finally the day of leading the lab session came , we were little nervous ,whether we would be able to explain the things to our peers and clear their doubts.We started by explaining some basic linux commands like ps, top, kill etc. and asked the students to try them out .After that we initiated our main task of teaching the commands grep ,sed and awk and their application.After telling them the working of the commands we asked them to solve the problems using the above commands.We tried our best to clear their doubts. Most of the students were very cooperative even when we took some 10-15 min extra.
Just want to sum up by saying that we enjoyed leading the lab session very much and want to thank Amarjeet Sir, TA's and the students for their support.

On the training day, when I saw the questions in the handout , they seemed really tough.But after some time, after we got used to the commands and a bit of help from our T.A. and google ;) , we were able to solve most of the problems. But it took a lot of time , about 5 hours(although we spent 1 hour playing table-tennis).
And now , the "D-day" (as coined by some of my peers) arrived. We were kinda nervous on that day, because we weren't sure if we would be able to explain everything.We started after everyone was on their seats and had a terminal. I started off with the basic commands and then went over to explain basic usage of sed, grep and awk commands.Then Nikhil took over and gave the class the questions to solve . We tried to and hopefully clarified the doubts of everyone.Everyone surprisingly co-operated with us even when we had exceeded the usual time limit of the lab. I was impressed by the enthusiasm shown by some of my friends in learning the usage of commands.
Overall , it was a very good experience and we got to learn a lot from it.Plus , I didn't had to study extra for my lab exam;)

The topic that we were allotted was not only tough but also challenging enough to be taught. Besides that it was also boring as well.
Our training for the lab session that was taken by a MTech student was not up to the mark as she herself had not prepared well. So before the day when I had to lead the lab session ,we had to refer to various sites to enhance my knowledge as well as clear my doubts .
On the day that I had to lead the session , I had viral fever which made the things worse for me. During the lab session as it was boring topic to be taught it was difficult to gather the interest of the students. Clearing many of their doubts as well as teaching them a difficult topic was a challenging task. However many students helped us a lot by leaving the class well before time.
But at the end of the day it was a satisfying experience after I got good reviews from my peers regarding the lab session.
We would first like to tell everyone what we felt about this idea of students leading Lab sessions.It was not a surprise as coming from Amarjeer sir,we do expect some interesting ideas that structure his teaching style.Though we would want to mention that he has his boundations. We all were soo happy that SM course would not have a theory exam,but then there are some college rules(and we all hate them). So,finally SM has it's theory exam.But about the part that SM is focussed about i.e. PRACTICALS , we can just say that students acting as LAB INSTRUCTORS not just gets in a sense of responsibility in us but also it gets us into the instructor's shoes and have the experience,know what an instructor has to go through before and during the session,the hardwork that is put into it. And for sure,now we actually know that it's not just about those 2 hours in the lab..it's much MORE..
And we can bet.. Once one goes through the experience,the training by Arjun bhaiya and Samy sir,feels the heat for 5-6 long hours,and then the practice and structuring of the lab session at home.., he can understand that it is not an easy job.It automatically makes you respect ur peers too when it's their chance to lead the lab session when it's their chance.
We got our chance ,finally, in the 4th lab session that was about
utilities in Linux and windows.Well,at first look,anyone would find the windows part pretty boring,because we've been doing it all these years,though the LINUX part was new to us.
Once Samy sir started,we were a little amazed,both of us never knew that a tast manager could do soo much in windows,or may how can we utilize a task scheduler,it was fun then.However,the LINUX part was much more intensely taught,most of those things that we never knew.It was too not even 2 hours that all of us got so tired that we asked sir for a pool break,we played some pool and then we were back in form.haha..3 more hours after that and we all went back,it was raining and all of us really enjoyed the trip back to our homes.
Well we had almost a week to prepare the lab session as group I used to have it's lab session a week later than every other group. So,the week just went by,and it was weekend already,we called each other up and structurised the whole lab session,we decided that I would do the LINUX part and Apoorv ,the WINDOWS part.We also decided how much time we would spend on each topic and we were done.It took us almost 2 hours to structure that and then another 4-6 hours for getting into the details of each command.Also,we just revised everything we wanted to do the next day.
Finally,It was the D day,23rd August,Lab session 4,Computer Lab -1.We had almost full strength that day and it was really funny when each of them wished us ALL THE BEST before getting into the lab.We started on a very DHAMKI-BHARA note that "Please co-operate with us and grade us whole heartedly,and remember,you will also be standing here sooner or later"..hehe..
We started and felt it was going very smooth,with I and Apoorv doing all the topics together regardless of it was of WINDOWS or LINUX because we were now thorough we all the topics and all the utilities.It was annoying to have Akshit asking funny questions but we never let our emotions let go,it was also making us nervous when Amol or Adway would ask a technical question,but then we could answer all the doubts without fail and it felt really awesome..It was a fulfilling experience to see everyone learning,enjoying and we were the instructors(The best part)..Well,this was something that the two of us would never forget as it was us,who were teaching our peer group,helping them as if we were the bonds of those utilities..
All we can do now,is thank Amarjeet Sir for giving us the opportunity,the chance to experience what he luckily experiences each day.
Arjun and Apoorv
I arrived late for the training sesssion but still managed to understand just enough so as to be able to understand the language in which the previous handout was written...
We were nervous on D'day but still managed to get through with it somehow...
There were a few hiccups...
We didn't remember the command used in QEMU, some computers weren't working and most importantly, (and i remember this distinctly)it was a very hot day and the AC wasn't working!!!
But overall everything went well. Almost everyone was able to install Ubuntu as dual-boot and also using virtual box(we didn't get to try out vmware tough).
I'm glad we chose to do that lab session as consequent sessions seem to be getting harder and I have no idea how the other group leaders manage.
I would also like to thank everyone in group 4 for being understanding and patient.:)

During the lab,i was really scared about amol and arjun asking tricky questions but it went along fine during the lab.. although there were few computers in which the commands weren't responding but we eventually gave our best shot..the lab timings also got extended till 4:45pm,me and akshit eventually got pretty exhausted by the end of the lab!!..and that day i really understood the effort our faculty puts in to teach us.. hats off to our faculties!!!...
overall it was a nice experience and learning one too!!!
Comments are always welcome :)

Even though I didn't have a very challenging topic (Installing Multiple OS), it was very difficult to prepare enough to make sure that I could explain the topic to other students. It took me about 2 hours to prepare for the lab session (I didn't attend the training session), but I didn't know that we weren't going to cover all the methods of installation.
The lab session turned to be surprisingly easy to handle. The teaching assistants occassionally gave some input to us about how we should handle the class. The class didn't misbehave much (mainly because they were afraid of us giving them a bad evaluation when it was their turn to lead :P), and the lab session went along smoothly.
It was great using QEMU and VirtualBox, but I found myself wishing that we could use VMWare Player too. It would also have been nice to have been able to install a version of Windows as a virtual machine.
Personally, I thought that Lab Session 3 was one of the most useful lab sessions because almost everyone used the knowledge they gained during the session later, installing a Linux - based operating system.
I along with my partner Manik turned up for the training on 14th Aug 2010. I was actually late for it because the previous day we had our Freshers Party and that had left me completely tired. Samy sir took our training that day. And I must say he was pretty well prepared for it. He knew almost all the questions that I asked him. We were actually present in the lab for 4 hours barring a 5 mins break in between. And our training wasn't even complete then. We only managed to cover the Windows part. The Linux part was yet to be covered. At the end of the training there was one thing of which I was sure of, 'A huge task lay ahead of me!'.
I sat down with Manik on monday and divided the sub-topics between us. We took alternative topics so that none of us would be speaking for a longer time. We researched a bit 'Wikipedia' and noted down the things that we felt important and should be told to the class. We decided that while one of us would be explaining the topic to the class, the other would be going personally to everyone, asking them their doubts and clarifying if any. So that no one feels left out and everyone is happy with our performance. :P
The main problem that we faced was how to finish a lab session in 1.5 hrs when the training itself took 4 hours. Samy sir had told us that he would be teaching Linux to the class in the last 0.5 hr.
The day eventually came. And I can't even tell you how nervous I was before it. I had butterflies in my stomach and my face completely reflected the state of my mind at that time. The group 2 people can actually vouch for this! But somehow I suppose, I did manage it. ;)
I started off with proceedings and Manik took on from me really well. It didn't go as planned. Well now I have actually started to believe that nothing in life goes according to plan! But it still went pretty well, I suppose. :P
We started off as we had decided. The process was quite smooth except for a few hiccups! We did face a few problems, but we dealt with them with ease. The group 2 people were really helpful. They weren't asking much tricky questions. Well, I guess that was due to the fact that their turn was yet to come. But on the whole, they were quite understanding and sympathetic with me! :P
And before we knew it, we were over with it! :D
They basically had 2 complaints from us. Firstly that we weren't able to finish the lab before 4 p.m.! And secondly that this was the most boring lab session! The first one I accept was in our hands. But the second wasn't! :P
At the end of the session, I actually felt that I was a bit less prepared. I couldn't answer a few questions that my friends asked. I had to eventually say that I didn't know that and I would have to look that up. And I didn't at all like saying that. :|
To conclude, I would like to say that leading the lab session was good experience. You don't really get to step into your teacher's shoes everyday. I thoroughly enjoyed the leading part, although not the training and the part before it! :P
But it was nevertheless a good experience. Something which I would surely like to experience again! :)
Let me start with the training part. We reached for training on Saturday around 2:30 pm. And it continued till 6:30 in evening. For the first 2 hours, we were just staring at Arjun (our TA) trying to figure out what he was doing! Finally when we started doing on our own, we got it.
I was so tensed before the lab session. What all are my group mates going to ask? What if I cant answer? And after the lab session was over, i was laughing at whatever happened. It was a mixed experience. On one hand, I felt everything became chaotic. We (me n my partner, Monika) had to go to each table since everyone had reached to different steps. Plus, I felt we should have been a bit more prepared. On the other hand, was happy to see that ultimately everyone had installed linux natively and using virtual machines.
Lab finished in around 1.5 hrs. But that was for others. We had to stay back to uninstall linux now so that other groups can perform lab next day. So we stayed back till around 6:30 pm.
I learnt a very important thing through this process, that its easy to learn something. But to teach that to others, is really tough. But overall a very nice & enriching experience!! :)

Finally, wednesday came (the day I had to lead). We (I and my partner) were prepared but were nervous to think what questions would be asked by our group members (though most of our doubts were clarified by samy sir beforehand). the lab started at about 1pm. We started with the task manager and somehow ended in 1hour30min ending with task manager in linux (we were promised of good grades by the group if we end early, but it was not the actual reason why lab ended so early). The lab ended early because many of the windows utilities were known to the group except the utilities from sysinternals.com. After completing the interesting (especially the diskmon and rammap of sysinternals) windows utilities, when we decided to shift to linux utilities, passwords for most of the computers were unknown(blame the last lab group for that), so we had to show the linux utilities on 1 or 2 computers only(where fortunately login got possible).
When we ended before time , the whole group was happy(this is what their faces told) and even we were happy as a big chunk of tension was over(my mindset about that is still the same). I don't know the grades i got but it was a different experience of acting as a teacher and trying to order someone(i tried once after i was told by arjun sir that i can do that). Initially, even i was not interested but once you try well, you somehow succeed. All that starts well, ends well.

If I can describe this experience in two words, I will say it was an enjoyable 'labmare'.Weird it might seem,but indeed, it was a sort of problematic challenge that ended quite well...
The idea of conducting a lab seemed interesting.We were very eager to try it out as early as possible, but got a chance only this past week.We were called for training on Saturday at 10 am, and as some of you might have anticipated, I was late yet again, and so I missed quite a bit of the explanation part...:-)
Soumya, then helped me out.I tried to understand everything that I had missed and simultaneously made an attempt to keep track of what was going on(Multi-tasking I may say).Unfortunately,it didn't help much, I could not understand what was going on.Thankfully, at that very instant,when matters seemed to be getting out of hand, Madhuri ma'am gave us a break...We went to play TT.We had a great,refreshing one hour.Then we returned to business.
The scene was quite different now, I seemed to understand things better now.Soumya and I tried our hands out on the questions along with our friends from the other sub-groups.We all put our heads together, and finally things seemed to be in place.An exciting day,I must say.
Then began the difficult part.Understanding the things, was easy, but explaining them to others was not going to be.So we put in our efforts,tried to understand the concepts, practiced a little more.And got ready for the day.
(Oh boy!!it was tiring...)
With little confidence,I started the lab session.My mantra "tension kis baat ki hai" really helped.Though, my confidence was low, but I managed to bring conviction in my voice :-).
The lab went on quite well.We were able to help our mates out.They had no complains(at least this was what I felt).Moreover, we got to learn a lot from our group mates, who came up with doubts, that needed some on the spot research.(I was ready for it and so I was carrying a book on LINUX commands :-D).
So on the whole, it ended pretty well.But the effort that went into it made me realise one thing-"Teachers ko toh bohot jyada mehnat karni padti hogi!!"
Thank you sir, for this opportunity, but I would not like to do it again.
Being on the receiving end is much easier... :-D

It was apparent that you guys had put in effort preparing for it. Thank you for preparing the wonderful performances. I hope you continue putting in efforts not just in this course but in your education all through.
Those of you who took the videos and photographs, can you please share them on the blog or wherever you feel comfortable. And the group working on video editing as their project should see if they can create some good video about this course out of these videos.
