Using the notation exemplified in following question , list a set of tables and attributes (and identify keys) to represent the
following data:
In a very simple school database, students have a student ID and a name. Each student has only one advisor (who has an ID and a name). Each advisor advises many students. Students take many courses. Each course has an ID, a name, and the number of credits. The database also stores when a student took a course (the semester/year) and his/her final grade for that course (on that semester).

Answer:
6 hosts can have IP addresses on the LAN attached to the router interface
Explanation:
Given IP address
=> 192.168.192.10/29
It has a subnet mask of /29 which means it has 3 host bits. This is calculated by subtracting 29 from 32(number of bits in an IPV4)
Since there are 3 host bits, the total number of possible addresses is given by
=> = 8 possible addresses.
Out of these 8 possible addresses, the first address will be the subnet id and the last address will be the broadcast address.
Therefore, there are only 6 addresses available for the hosts.
