Machine Specs

Are you a gamer? If yes, then you should be familiar with this term, computer specs, basically if you ask about specs, the common things that will be stated is its computer processor, word size and its screen resolution.
Well if you are an RTS or Real-Time Strategy gamer then you should have at least a minimum of 3gHz processor and a 1024 by 768 screen resolution.
Word size doesn't matter too much when it's speaking of computer specs.
They are just commonly 32 or 64 bit but commonly computers have 32-bit computer.
OS(Operating System) is another term that you should be common with.
An OS has backward compatibility which means you can play a Windows XP game on a Windows 8 computer.
But you cannot play Assassin's Creed on Windows 98 or simply you cannot play a game with a newer operating system requirement on an older version of an OS.
Well, I hope that this helped... =)
