A system administrator is trying to find out what devices are connected to a Linux system. Which of the following commands can be used to do this?0.5 Marksfdisk -llsblk lsmoddmesg

The command "lsblk" can be used to find out what devices are connected to a Linux system. This command lists out all the storage blocks, which includes disk partitions and optical drives. Here is how you can use it:

1. Open a terminal window. This is usually done by searching for "terminal" in your system's main menu.

2. Type in the command "lsblk" and press Enter.

3. The terminal will then display a list of all connected devices. This includes the name of the device, its size, and the type of device it is.

The other commands have different uses. "fdisk -l" lists out disk partitions, "lsmod" shows the status of modules in the Linux Kernel, and "dmesg" displays the message buffer of the kernel. While these can give information about the system, they do not directly show what devices are connected like "lsblk" does.
