The user can click on any of the categories to find out the lab of his preference. The user can also search for the virtual labs on the home page itself. There are two search options:-

1. Search by the name of the Virtual Lab: Here the user can type-in the name of the virtual lab of his preference from any institute or Discipline.
2. Search by Discipline: Here the user can choose discipline of his preference from the drop down menu. After searching the desired Virtual lab, the user has to make a single click on the link, which would take him to that particular Lab-specific home page. This method of accessing the virtual lab is common to all the Labs available on the vlab.co.in homepage.

Simulation Based Virtual Labs:  In these Virtual Labs, the experiments are modeled using mathematical equations.  The simulations are carried out remotely at a high end server, and the results are communicated to the student over the internet.  This class of Virtual Labs, at best, mimics the real-world scenarios/experiments.  Simulation based Virtual Labs are scalable and can cater to a large number of simultaneous users.

Remote Triggered Virtual Labs: In these Virtual Labs, the actual experiments are triggered remotely.  The output of the experiment (being conducted remotely) is communicated back to the student over the internet.  This class of Virtual Labs, gives the student the output of real-time experiments.  Remote Triggered Virtual Labs are difficult to scale and can cater to a limited number of users.  Typically, time-slots are booked before conducting such experiments.

1. Simulation based Labs: Many of the simulation based labs do not require registration. You can directly perform the experiment without registering yourself. On the other hand, some of the simulation virtual labs require registration for which the user can go to the respective website do a one-time registration.
   
   
2. Remote Triggered Labs: To access a remote triggered lab, a user has to book a slot. For booking a slot, you have to register yourself first and then book a slot from the slot chart. All the available /booked slots can be viewed on this chart. Once a request for slot-booking is made, all the information regarding the user id, password and the slot booked will be sent to the user’s email address provided by the user at the time of registration. Once registered, a user can login using the same credentials every time. This registration has to be done by the user separately for each of the remote triggered virtual labs.
