Does Linux expose this information in some file that I can read in to get this information?
What are some good resources to read about such linux internals?

1. Number of CPU Cores
2. Number of CPU Sockets
3. Number of Disks
4. If it's a 4 socket processor then which 2 sockets are adjacent to each other
Yes, information about CPUs and Disks is available in Linux.
/proc/cpuinfo contains detailed information about the CPU.
e.g. cat /proc/cpuinfo
The command sudo fdisk -l provides a listing of disks and their related information.
This link provides some specifics regarding /proc/cpuinfo.
This link explains the usage and output of sudo fdisk -l.
lsblk is a better option for that. Where to look for info? tldp, google, /usr/share/doc
