lshw is a command line tool that displays detailed information about hardware components on a system. This tool can display details about CPU, RAM, network interfaces, USB controllers, and much more.
This tutorial explains how to install lshw on Raspberry Pi and run some commands.
sudo apt update sudo apt install -y lshw
In order to get detailed information about all hardware components, run the lshw without any arguments:
sudo lshw
You can use -short option to retrieve brief information about the hardware components:
sudo lshw -short
Here is what I saw running this
user@raspberrypi:~ $ sudo lshw -short

Display only memory information
To display information about the memory, specify the memory class
$ sudo lshw -short -class memory
Display processor information
With class processor, lshw would display information about the cpu. It is better to not use the short option and get full details about the processor.
$ sudo lshw -class processor
Disk drives
Display the disk drives with the disk class.
$ sudo lshw -short -class disk
Network adapter information
Use the network class to display information about the network adapter/interface. Omitting the short option is a good idea to get detailed information about it.
$ sudo lshw -class network
Display address details with businfo
With the businfo option lshw would output the address details of pci, usb, scsi and ide devices
$ sudo lshw -businfo
