I doubt a newbie knows the difference between a thread and a process.

Threads share all memory and global variabls.  They can communicate
with each other through global variables.

Processes are completely isolated from each other and much communicate
with each other through mechanisms provided by the OS (e.g. sockets,
mailboxes, pipes, files).
