What do the different groups on NSE and BSE mean

Stocks are classified in NSE and BSE in different groups or series based on some qualitative and quantitative parameters. These parameters include market capitalization, settlement cycle, trading liquidity, etc. Stocks are categorized into different segments to distinguish them from each other. This categorization enables traders to know the risk they have undertaken by investing in these stocks.
