Before 1990, the technologies available to internet users were quite limited compared to what we have today. Here's a brief overview of the options you mentioned:
-
File Sharing: Early forms of file sharing existed, primarily through protocols like FTP (File Transfer Protocol), which allowed users to upload and download files from servers. However, this was not widespread in the way we think of file sharing today.
-
Online Shopping: While the concept of online shopping began to emerge with early e-commerce platforms and services, it was very rudimentary before 1990. The first secure online transaction is often attributed to the late 1990s, so actual online shopping as we know it was not prevalent.
-
Streaming Video: Streaming video technology was not available before 1990. Video streaming requires significant bandwidth and compression technologies that were not developed until later.
-
Cloud Computing: The idea behind cloud computing began to take shape in the 1990s, but before 1990, there was no real cloud computing in the modern sense. Most computing was done on local machines or within local networks.
In summary, before 1990, file sharing (via FTP) was the only technology somewhat usable, while online shopping, streaming video, and cloud computing were not established technologies at that time.
