How many active internet website there is on internet?

Hi, thanks for your question. I think the case is essentially testing your ability to segment a massive concept like 'internet websites' to its components. Below is my answer for this case:

Assume one website represents one particular entity (e.g. LinkedIn is one website and not multiple web pages)

No. of active internet website = [No. of government websites (e.g. US Department of Justice, Ukraine's Telecommunications Commission etc.) + No. of Private Sector websites (e.g. Facebook, McKinsey, UBER etc.) + No. of NGO websites (e.g. Oxfam, Red Cross etc.)] x 1.1 (10% for others that don't fall into this category like random personal websites you're developing out of interest, school work, pilot project etc.)

No. of government websites = No. of countries x Average no. of industries per country

No. of Private Sector websites = Average no. of companies x No. of industries

• If more detail is required, average no. of companies can be broken down to family businesses, SMEs, and large corporations. I would advise you to size based on a medium-sized country and just use that to multiply by the total number of countries

No. of NGO websites - Similar as No. of Private Sector websites

Hope this helps in any way and happy to get comments/feedback on this - thanks!
