    Salesforce runs on a multitenant environment which means resources (Storage, CPU, Memory) are shared with other companies on the Salesforce platform. This means limits must be in place to ensure that all companies using the Salesforce architecture abide by certain rules and don’t let their code or processes monopolize shared resources. A few examples of Governor Limits are:

    Total number of records retrieved by a SOQL query – 50,000
    Total number of SOQL queries issued – 100 (Synchronous) 200 (Asynchronous)
    Total number of DML statements issued – 150
    Total number of callouts (HTTP requests or Web services calls) in a transaction – 100
    Maximum CPU time on the Salesforce servers – 10,000ms (Synchronous) 60,000ms (Asynchronous)

    Adding some points:

    In a SOQL query with parent-child relationship sub-queries, each parent-child relationship counts as an additional query. These types of queries have a limit of three times the number for top-level queries.

    The row counts from these relationship queries contribute to the row counts of the overall code execution.

    In addition to static SOQL statements, calls to the following methods count against the number of SOQL statements issued in a request.

    Database.countQuery
    Database.getQueryLocator
    Database.query
    From above statement i can clarify one point:

    For example your org contain  only 2 Account and each have 10 Contacts.

    If you execute this with sub Query like below

    Select Id, Name, (Select Id, Name from Contacts) From Account

    Then the total number of Query rows will be 22 (2+10+10).

    From above analogy we can understand like this

    If your org contain 40M accounts and each have 1 contact.

    Then in this scenario you can use sub query up to 25M only.

    Like this Select Id, Name, (Select Id, Name from Contacts) From Account limit 25M

    Thanks
