CHANGES IN SIZE
Early computer systems were very bulky in nature as a result of their high metallic component. Internal hardware such as transistors were often times larger and heavier than the modern computer. Even though they are now in the minority, there are still some computers that are bulky in structure but are relatively easier to handle. In the past, the Central Processing Units (C.P.U.s) used to lay flat, which had its advantages as monitors could be placed on top for space efficiency. Monitors today are flat and easier on the eyes for display purposes as they can be positioned on almost any surface without the bulky back section that previously existed.
CHANGES IN INTERFACE
In the early stages of this industry for each action to be performed, a series of commands would have to be entered. These manually entered commands were know as Disk Operating Systems(D.O.S.s). With the creation of G.U.I.(Graphic User Interface), users of computer systems have the choice of simply pointing, clicking, and or dragging to do an action. Now, to become computer literate is an easy process that can be self- taught.
CHANGES IN SPEED
The type of interface in which each computer system operates on is an important factor in determining how much time it takes for an output to be generated. For example, a graphical user interface is less time consuming to select and execute commands than a disk operating system. More time-efficient input speeds consequently reduces the execution time as commands are simple and faster internal processing components are available. Hence, the creation of the G.U.I. has significantly increased the overall speed of present day computer systems.
CHANGES IN EXTERNAL STORAGE

In the past, there were only a limited number of storage devices. Information either had to be stored on the computer or on a floppy disk. Floppies were problematic as they were easily ruined and offered a very limited amount of storage space. Thanks to changes in technology, today there are a numerous amount of ways by which information can be stored. These include CD's, flash drives, Ipads, external hard drives and even cellular phones.
CHANGES IN INTERNAL STORAGE

As seen in the table above, there has been a continuous reduction of prices and a simultaneous increase in the storage capacities that are available.
