Just like Windows, iOS, and Mac OS, Linux is an operating system. In fact, one of the most popular platforms on the planet, Android, is powered by the Linux operating system. An operating system is software that manages all of the hardware resources associated with your desktop or laptop. To put it simply, the operating system manages the communication between your software and your hardware. Without the operating system (OS), the software wouldn?t function.
Linux is the best-known and most-used open source operating system. As an operating system, Linux is software that sits underneath all of the other software on a computer, receiving requests from those programs and relaying these requests to the computer’s hardware.
For the purposes of this page, we use the term “Linux” to refer to the Linux kernel, but also the set of programs, tools, and services that are typically bundled together with the Linux kernel to provide all of the necessary components of a fully functional operating system. Some people, particularly members of the Free Software Foundation, refer to this collection as GNU/Linux, because many of the tools included are GNU components. However, not all Linux installations use GNU components as a part of their operating system. Android, for example, uses a Linux kernel but relies very little on GNU tools.
Every version of the Linux operating system manages hardware resources, launches and handles applications, and provides some form of user interface. The enormous development community and wide range of distributions means that a Linux version is available for almost any task, and Linux has penetrated many areas of computing.
There are many utilities available to check Linux system hardware information. Some commands report altogether like CPU, Processor, memory, storage, disk, etc,. and the rest will cover only specific hardware components like CPU or processor or memory, etc,.
lspci command shows what your systems have got internally. The command is a combination of ls, the standard command to list files and PCI that is for the peripheral connection. You can also expect your results to include AGP and onboard components like your USB chipset.
lspci stands for list PCI devices. lspci command is used to display information about PCI buses in the system and hardware devices that are connected to PCI and PCI bus.
It will display information about model number/chip details for devices like PCI bridge, VGA controller, Ethernet controller, USB controller, Audio device, IDE interface, etc,.,
The command is much helpful in diagnosing bugs related to PCI devices. Using -t option of lspci command you can see PCI layout in a tree format.
lshw (Hardware Lister) is a small tool to provide detailed information on the hardware configuration of the machine. It can report exact memory configuration, firmware version, mainboard configuration, CPU version and speed, cache configuration, bus speed, etc. on DMI-capable x86 or EFI (IA-64) systems and on some PowerPC machines.
