Building my new rig

CPU is the brain chip, the most important chip in the computer. It stands for Central Processing Unit. The number after "Intel" in this case is a model number. and "4.0" is just a newer version. Just like software Windows goes from Vista, to Windows 10. You can think of a CPU like a CEO of a company or a store manager, the top thinker of the computer, the coach of the team, the general of the army.

The 4.0 in this case is actually the speed of the processor in teterms of how many decisions or tasks it can cycle per second. This processor has 4 cores (quad core), each running at 4 GigaHertz, or billion cycles per second.

HDD is the Hard Drive, much like you write things on paper and keep it in a notebook binder.

SSD is simply another type of drive, accept it connects from the outside of your computer to a port.

Almost right. HDD stands for Hard Disk Drive, which is essentially a at stack of spinning metal disks sandwiched together, which store non volatile memory, stuff like documents and images that need to be stored and retrieved at will.

SSD is a solid state drive. It serves the exact same function, non volatile memory, except it uses flash memory, (like a USB stick) no spinning disks. It can be external, yes, but it can also be internal. In this case, this SSD is inside the computer case, connected directly to the motherboard. It is called m.2, and it uses a lightning fast connector which makes it good for installing your Operating System(s) on it, and leaving the HDD for all if your files. This way, your computer will boot in seconds rather than minutes, and grabbing system files uses very little RAM and no disk power.
