FACTS
Technology Facts
Learn how everyday digital systems work, from web pages and data to networks and software.
A URL can identify more than a web page.
URLs can point to many kinds of network resources, depending on the scheme and server.
Databases are designed for structured data.
Database systems provide ways to store, organize, query, and update information rather than treating every item as an unrelated file.
Source code is not the same as a finished program.
Source code is the human-readable instructions developers write; software can then be compiled, interpreted, or otherwise executed.
Passwords are not ideal as the only security factor.
A second factor can reduce the impact of a stolen password by requiring additional evidence of access.
HTML and CSS have different jobs.
HTML provides document structure, while CSS describes presentation and layout.
Cloud computing uses remote infrastructure.
Cloud services let users access computing resources over networks instead of requiring every workload to run on a local machine.
Backups are different from synchronization.
A backup preserves a recoverable copy, while synchronization is primarily about keeping versions of data aligned across locations.
Compression can reduce file size.
Lossless compression can restore the original data exactly, while lossy methods trade some information for greater size reduction.
Search engines use automated systems to discover pages.
Crawlers can fetch publicly accessible pages, after which search systems process and index information according to their own systems.

Frequently Asked Questions
Are these facts meant to be memorized?
They can be used for quick learning, but understanding the explanation is more useful than memorizing isolated sentences.
Can a fact have exceptions?
Yes. Scientific and technical statements often depend on conditions. The explanations here use the ordinary context stated by each fact.
