              Dial up connection is the more popular and conventional mode of connecting to your ISP.  At present VSNL is the predominant ISP in India, though many other ISPs are gaining recognition.  VSNL provides this service through its 'Gateway internet Access Service' (GIAS)  Two types of accounts are at present offered by VSNL shell account and TCP/IP account.
              The shell account is cheaper but it is restricted to text based internet access only.  That means,  you will not be able to see pictures,  graphics,  images etc.  This account is good for e-mail services and for beginners to get initiated into internet.  Access to the net is faster in shell account. The TCP/IP account is more expensive but allows you to access text,  graphics,  images,  video,  etc. That is available a plenty on internet. Access is slower as compared to shell account.
