4 generations of computers.
Next generation of computers.
Now theres some history!
1st generation!
It is the Bendix G-15 General Purpose Digital Computer, a First Generation computer introduced in 1956.
2nd generation!
3rd generation!
The Fourth Generation.
Inputs and outputs!
An input is data that a computer receives. An output is data that a computer sends.
Computers only work with digital information. Any input that a computer receives must be digitised.
Often data has to be converted back to an analogue format when it's output, for example the sound from a computer's speakers. An input device is something you connect to a computer that sends information into the computer. An output device is something you connect to a computer that has information sent to it.
Hard Drives!
Monitors!
Most monitor windows will also have buttons that allow you to add in and out points to select a segment from within a larger video clip.
CPU!
Central Processing Unit.
RAM/ROM!
RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers.
Once data has been written onto a ROM chip, it cannot be removed and can only be read. Unlike main memory (RAM), ROM retains its contents even when the computer is turned off. ROM is referred to as being nonvolatile, whereas RAM is volatile.

Motherboards!
A motherboard (sometimes alternatively known as the mainboard, system board, planar board or logic board, or colloquially, a mobo) is the main printed circuit board (PCB) found in computers and other expandable systems. Alternatively referred to as the mb, mainboard, mobo, mobd, backplane board,base board, main circuit board, planar board, system board, or a logic boardon Apple computers. The motherboard is a printed circuit board that is the foundation of a computer, located at the bottom of the computer case. It allocates power to the CPU, RAM, and all other computer hard ware components. Most importantly, the motherboard allows hardware components to communicate with one another.
