Sysinfo (system information) covers the ways to query the state of hardware and the operating system on Linux. The kernel provides overall statistics such as uptime, load average, and memory and swap usage through the sysinfo() system call, and exposes per-device details in /proc and /sys. On the command line you check them with individual tools such as lsusb, lspci, and lscpu, and in a graphical environment with programs like hardinfo that gather various information on a single screen.
