ATX: The 'standard' size.
micro-ATX: Smaller than ATX.
mini-ITX: Even smaller still.
where the virtualization occurs at the firmware level
where the virtualization is done by a software program
that runs on an operating system
kind of connector that the CPU processor has
responsible for moving data btw components
The internal operating unit or "brain" of a computer.

the smallest unit of data in a computer
All data in a computer system is made up of bits:
1 byte is 8 bits.
1 kilobyte (kB) is 1000 bytes. Bits
1 megabyte (MB) is 1000 kilobytes.
1 gigabyte (GB) is 1000 megabytes.
1 terabyte (TB) is 1000 gigabytes.
Oh, and 4 bits (half a byte) is called a nibble...
1 byte is 8 bits.
1 kibibyte (KiB) is 1024 bytes.
1 mebibyte (MiB) is 1024 kibibytes. 1024 Byte
1 gibibyte (GiB) is 1024 mebibytes.
1 tebibyte (TiB) is 1024 gibibytes.
