This article totally deals with how to get access to root user in UBUNTU? So going in to topic, by default Ubuntu will not allow us to log in to root user because root user is super user and we can do any thing if we have root access.Actually be default in Ubuntu root user is disable(means there is root user without password set). So if we try to login to root user it will not allow us because there is no password set to that user.So the solution to this problem is to set the password to root user so how to do that? A question arises? Ans : In order to change the root password we have to log in to run level1.if you are new to this run level concept you can get that one here. In order to go to run level.Step1 : Reboot your Ubuntu system if it’s on other wise start your ubuntuStep2 : Brake the timer when it’s displaying OS choice at the boot time. To brake the timer press any key. So now we will get 3 lines like below. ubuntu, kernel 2.6.18-genericubuntu,kernel 2.6.18-generic(recovery mode)ubuntu,MeM test86+Like this you will find at the display. Select the first line by up/down arrows and then press “e” to edit that line. And here again you will get some 3 to 4 lines. Select the...Read More

1950 : The history of computer operating systems starts in this year, with simple schemes for running batch programs(running programs in groups these prog will not interact with user) efficiently, minimizing idle time between programs. 1960’s : Interactive use of systems started to gain ground. Not only interactive use, but having several people use the same computer at the same time(noting but multi user), from different terminals. Such systems were called time-sharing systems and were quite a challenge to implement compared to the batch systems. 1965’s : There were many attempts at building good time-sharing systems. Some of these were university research projects, others were commercial ones. One such project was Multics, which was quite innovative at the time. It had, for example, a hierarchical file system, something taken for granted in modern operating systems. This multics was the project of combined effort of Bell Lab’s, MIT,GE. The Multics project did not, however, progress very well. It took years longer to complete the anticipated and never got a significant share of the operating system market. One of the participants, Bell Labs, withdrew from the project. The Bell Labs people who were involved then made their own operating system and called it as Unix. 1969 : First UNIX 1 was released. 1970-1989 : So many flavers of unix came at this time depending on the lack of feature’s in the...Read More
