What is CPU cores in Linux?
Physical cores are just that, physical cores within the CPU. Logical cores are the abilities of a single core to do 2 or more things simultaneously (through the use of hyper-threading) We can get the number of physical and logical CPU cores using lscpu command in Linux as follows.

How many CPU cores do I have Unix?
You can use one of the following methods to determine the number of physical CPU cores. Count the number of unique core ids (roughly equivalent to grep -P ‘^core id\t’ /proc/cpuinfo | sort -u | wc -l ). Multiply the number of ‘cores per socket’ by the number of sockets.
How do I know how many virtual processors I have?
The amount of virtual processors available are determined by the number of cores available on the hardware. So as an example, if you have a 4 socket server where each processor has 8 cores, this will present 32 logical processors.
