lscpu output looks like-

Architecture:          x86_64
CPU op-mode(s):        32-bit, 64-bit
Byte Order:            Little Endian
CPU(s):                4
On-line CPU(s) list:   0-3
Thread(s) per core:    2
Core(s) per socket:    2
Socket(s):             1
NUMA node(s):          1
Vendor ID:             GenuineIntel
CPU family:            6
Model:                 69
Stepping:              1
CPU MHz:               1200.093
BogoMIPS:              3392.08
Virtualization:        VT-x
L1d cache:             32K
L1i cache:             32K
L2 cache:              256K
L3 cache:              3072K
NUMA node0 CPU(s):     0-3

The output shows the pc has 1 socket and 2 cores per socket. Probably this socket is not networking socket.

You’re right! The socket in lscpu’s output refers to the physical socket which the processor package sits in, on the motherboard; a networking socket typically refers to BSD sockets.


lscpu does not list networking sockets. As per the above output there is 1 socket and it has 2 cores and each core has 2 CPUs.
