Hypertext • Hypertext is a system of storing images,
text, and other computer files that allows direct links to related text, images, sound, and other data.

Hypertext• Hypertext is the main basis of operation
for the web.• The term "hypertext" was coined by TED

Hypertext
Hypertext is the presentation of information as a liked network of nodes which readers are free to navigate in a non-linear fashion. It allows for multiple authors, a blurring of the author and reader functions, extended works with diffuse boundaries, and multiple reading paths
Hypertext links called hyperlinks create a complex virtual web of connections for users.
Hypertext, at its most basic level, is a DBMS that lets you connect screens of information using associative links
Hypertext is a software environment for collaborative work, communication, and knowledge acquisition. Hypertext products mimic the brain's ability to store and retrieve information by referential links for quick and intuitive access

Hypermedia
Hypermedia is a style of building systems for organising, structuring and accessing information around a network of multimedia nodes connected together by links.

Hypermedia
We can distinguish hypermedia systems in two generations
First generation hypertext systems were mainframe based, text-only systems for augmenting the performance of information processing environments, storing the whole world's literature or for supporting traditional writing and reading.
Transition from hypertext to hypermedia took place with the Second Generation Systems.
