How do I check system specifications?

I am total noob in Linux. I wanna know what is the equivalent of "My Computer" in Ubuntu 11.04. I want to check my computer specs such as Processor Speed, Memory, and etc.

Whenever I check properties in Home Folder it only gives me the HD capacity. I also tried looking at System Settings but I can't find it there. Please help.

Hit Super (Start button in windows) , Type and and open System Monitor.

For full details system information use HardInfo : Click to install.

HardInfo can display information about both your system's hardware and operating system.

for command line solutions, you can use the command lshw.

Install it if needed:

sudo apt-get install lshw

then run something like

sudo lshw -html > mySpecs.html

then check the html file.
