7.1 Development of Multimedia Technology


Multimedia has been around for longer than we think.
The first ever existence of some sort of multimedia took place thousands of years ago in the shape of
cave paintings painted by cavemen (see Figure 7.1 for an example).
Cave paintings were thought to be painted for communication purposes.
Cavemen used paintings to communicate with one another.
Such ancient multimedia content proved also useful in communicating with generations to come.
Thousands of years after, up to this day, multimedia is still being used as a way to interact and
communicate between people.
Computers have played a huge part in developing and enhancing the multimedia experience.
They have developed a great deal throughout the years since they were first made in 1939.

In 1939, the first automated digital computer was made by John Atanasoff and Clifford Berry.
It was called the 'ABC computer' (Atanasoff Berry Computer). In terms of multimedia, the ABC
computer did not offer much as it was only designed to solve mathematical (linear) equations.
It was however, the building blocks of all computers from then after as it implemented three ideas
that are still being used in computers today:
Used binary digits to represent all numbers and data.

The use of electronics to perform calculations instead of wheels of mechanical switches.
Separation of computation and storage.
Computers from the 1930s up to the 1950s were developed to calculate and solve mathematical
equations or break codes (Colossus), see Figure 7.2.
They were called the first generation computers.
They used vacuum tubes and magnetic drums and were enormous in size.
From the 1950s to 1960s, second generation computers were created.
Vacuum tubes were replaced by transistors which made the computer a lot smaller and faster
in terms of processing data.
Third generation computers 1960s to 1970s were developed using integrated circuits.
The transistors used for the second generation computers were miniaturized and placed on
semiconductors silicon chips.
This also made the computers more efficient and faster.
For the first time in computer history, keyboards and monitors were produced and used with
computers instead of punch cards.

In the 1970s, computers were being produced for the home user (fourth generation computers).
They came with a monitor, keyboard and an addition to third generation computers, a floppy disk.
Up till now, computers were only used for word processing and calculations, which were now being
carried out using spreadsheets.
As well as this, computers were command driven which meant that the user had to type in
instructions for the computer to execute.
In the 1980s, computers were further developed to accommodate a GUI (Graphic User Interface) and
the mouse was introduced.

This made computers a lot more user friendly and interactive as they were no longer command
driven.
In the 1990s, the CD-ROM drive was developed and CD-ROMs were extensively used by computer
users. CD-ROMs paved the way for the use of multimedia in computers.
Vast numbers of applications were installed on CD-ROMs that were used on computers.
Video games were a major hit as video and sound cards were widely available for users.
Word processing and spreadsheet packages were greatly developed as well to make them as
straightforward and easy to use as possible.
Monitor, speaker, keyboard and mouse are hardware components that were and still are a major
factor in enhancing the multimedia experience one receives.
They were greatly developed in the 1990s and as a result developed the text, audio and video the
user received from the computer, see Figure 7.3.

The widespread use of the internet at the beginning of this century has proved to be a revolution for
multimedia use and the sharing of multimedia between individuals.
Also, the advancement in software technology has aided in the production and enriching of multimedia
which is shared and viewed across the Internet.
Websites such as 'Youtube' and 'Facebook' accommodate different types of multimedia use and
are used by millions of users across the globe.
