20. FAX
FAX is described by Rouse (2006) as “the telephonic transmission of
scanned-in printed material (text or images), usually to a telephone
number associated with a printer or other output device.
The original document is scanned with a fax machine, which treats the
contents (text or images) as a single fixed graphic image, converting it into
a bitmap.
In this digital form, the information is transmitted as electrical signals
through the telephone system. The receiving fax machine reconverts the
coded image and prints a paper copy of the document”. This technology
helps us for providing various services, such as to send official letter,
communicate with the vendors, etc.
It is used in some academic libraries for document delivery and other
scholarly communications. It is a method of converting an image into
electronic signals that can be transmitted over a communication link and
converted back into an image at the receiving end.

One of the most important aspects of website authentication is
the focus on the user and human-to-computer interactions. As a
result, user authentication is crucial to understand when creating or
improving your website’s login procedure.
Authentication is important because it enables organizations to
keep their networks secure by permitting only authenticated users (or
processes) to access its protected resources, which may include
computer systems, networks, databases, websites and other
network-based applications or services.
31. CON….
User authentication is a security process that covers all of the
human-to-computer interactions that require the user to register
and log in
user authentication has three tasks:
Manage the connection between the human (user) and
the website’s server (computer).
Verify users’ identities.
Approve (or decline) the authentication so the system
can move to authorizing the user.
