Traditionally, films were made up of images printed on to acetate negatives which was the celluloid material back then. After splicing and sticking the frames together, the film was made up of roughly 24 frames per second.
The Moviola was invented in 1924 by Iwan Serrurier. It was the first device created that could allow a person to edit the film and view it at the same time and was also the first machine that was used for feature-length motion picture editing.
Video Editing
Before digital technologies became available for editing movie clips easily, magnetic tapes were used to store the information, instead of hard drives. These magnetic tapes are hardly used nowadays, if they even are anymore, due to them not being able to hold a lot of data on them and how easy it is to edit clips stored on hard drives now. The magnetic tapes are called VHS and VHSC tapes. The machine mechanically put clips together to form a sequence and everything had to be done in a linear fashion: meaning that you couldn't add a clip in near the end of the movie then go back to the start to add something else, everything was done from beginning to end in order. This type of editing is called linear editing.
Digital Editing
Digital media is a form of electronic media where is stored in digital form (opposed to analogue, digital is stored as bits, or binary, 1's and 0's which tell the computer what everything is, what everything looks like and how that thing is supposed to work).
Digital editing is the use of computers to manipulate the digital data stored on the hard drive. Compared to previous methods of editing movie clips, digital editing is the best, fastest and most efficient way of editing. Editing in any order, which is what digital editing allows you to do, is called non-linear editing. Programs that allow you to edit videos on a computer include Adobe Premiere Pro, After Effects, Sony Vegas Pro, Final Cut and many many others.
