PDF Full Form Name
Full Form of PDF:
Portable Document Format
PDF Full Form is Portable
Document Format. PDF is a file format that is designed to display documents
in a manner that they do not depend on upon the kind of operating system,
hardware, or software. One feature of PDF documents is that they have the
property to encapsulate details of a fixed layout flat document, along with all
the necessary texts, graphics, fonts, and other details necessary for display.
It was a system called Camelot, which developed into a PDF.
The world has become a
more convenient place to live, as far as the technological innovations are
concerned. The digitalization of the world has given way to a different
standard of lifestyle that functions on gadgets and the internet. Without these
gadgets, it is difficult to imagine working in a conventional manner. From
marketing to paperwork, everything is on the system. All you need to do is
purchase some minimum gadgets, which together give you access to the universe
of quick and convenience facilities.
Paperwork is a
cumbersome task, considering the fact that it is tedious to maintain. This is
due to its accumulating nature and vulnerability to damages or worse complete
destruction. Moreover, it is impossible to recover the lost paperwork and you
have to start anew. All of this has been significantly done away with by
computer technology. Computer technology is now a big role player in the field
of global change and with the help of its large variety of software and
hardware; it has become an essential part of private and professional life.
PDF is an amazing
platform that has greatly helped in the reduction of paperwork and improvement
in the digital access of files. It has replaced traditional file formats and is
becoming an excessively used format in the contemporary period. PDF has many
utilities that have changed the manner in which we use digital files. Inclusive
of independence, PDF provides to the users a much-wanted convenience in the use
of digital files by making them portable. Some of the utilities of PDF are as
follows:
History of PDF:
Technological
innovations are premised upon needs and improvement. Because the world is
driven towards a fast-paced, convenient lifestyle, computer scientists have
started to dwell on the possible way of improving the existing computer
services. It is the need and desired requirement of having a portable file
format that caused the invention of PDF, which now is one of the most popular
file formats.
The history of PDF can
be traced back to 1990s when other competing file formats like Envoy, Common
Digital Ground Paper, Farallon Replica, and PostScript format have entered the
market. People have slowly adapted to the usages of PDFs because earlier, Adobe
was not providing software for creating of PDF files free and in fact, the
earlier versions of PDF creating software lacked a reasonable number of
utilities. There were problems associated with such versions like slow download
speed of PDF files, poor reading capabilities of PDF files, etc.
Later, Adobe started
marketing its Acrobat Reader, which is now known as Adobe Reader, free of
charge since the launch of version 2.0. Since then many developments have been
made in the Portable Document Format and many versions of PDF creating and
reading softwares have come up.
Security issues with PDF
files:
One of the most
important questions raised in respect of PDF files is security. The digital
world is becoming exceedingly susceptible to security breaches, causing data
and information stored open to thefts. Thus, the question regarding security
inputs in PDF files is important.
A PDF file can have a
digital signature for authentication or encryption. Let us take up security
standards provided by Acrobat Reader, which is one of the most commonly used PDF
software in the world. The standard security provided by Acrobat has two
different methods and passwords. The two passwords are user password and office
password. The former deals with encryption of files so that they cannot be
opened without permission whereas the latter restricts specific operations,
where access to documents is restricted even though the documents concerned are
not encrypted. In the user password, password cracking is needed in accessing
the file. Therefore, it is advised that the password is rather difficult and
its strength is strong.
Changes in PDF features and
specifications:
PDF specifications
have been changed consistently to improve their overall performance and
utility. Some of the changes made in the Adobe’s PDF specifications have been
listed below:
§ In the first revised
version, encryption facilities like passwords were added.
§ In the second version
launched in the year 2000, new features like digital signatures; enhanced page
numbering; new annotation types, masked images, DeviceN color spaces, Web
capture, capturing information from the World Wide Web, etc were added.
§ In the third version,
RC4 encryption key with length more than 40 bits; improvements to Forms Data
Format; accessibility to persons with disability; a facility that allows import
of information from one PDF file into another, etc. were added.
§ In the year 2004, the
fifth version was launched with features like 3D artwork; AES encryption; Open
Type font embedding; NChannel Color Spaces, document sections for layered
artwork; facilities pertaining multi-language documents; assistance to rich
text elements, the introduction of PKCS#7 etc were added among many other
features.
§ In the year 2008,
features like 256 bit AES encryption, locale set typefaces, etc were added
among many other features.
Technical issues involved in
the use of PDF documents:
Although PDF is a
great format, there are issues attached with it that pose questions to its
utility. Some of the restrictions or issues with the use of PDF documents are
enumerated below:
§ When a PDF is
generated on scanning a hard copy document, then the so generated PDF document
will not have the same structural display as the PDF files of the same document
generated directly. The file size will vary and the facility to search within
the content of a PDF file will not be available in this case. Thus, such
documents cannot be used like other typical PDF documents.
§ Another problem with
PDF documents revolves around accessibility. A PDF document is capable of
having three different views, which may possibly be conflicting with each
other. The three views are Physical, the Tags, and Content.
§ Despite having been
designed to suit the needs of persons with disability, there are certain
aspects of PDF documents that still remain inaccessible to these persons like
tags and reflowing.
§ PDF documents are
susceptible to viruses and this was first discovered in the year 2001. The
virus was referred to as OUTLOOK
PDFWorm or Peachy. Soon after, many other viruses were discovered in PDF
documents that raised serious concerns among the computer scientists and users.
The problem with PDF documents is that where a webpage contains a PDF file with
viruses, it can take advantage of the PDF reader, which will, in turn, affect
the information stored in the database.
§ A technical issue with
display settings is also there, which up until today, remains unresolved. PDF
documents can save display settings and because of that, it has the tendency to
override the user’s settings. What is problematic is that there is no way to
change these settings.
PDF Software:
Currently, there are
many softwares circulating in the market that generally provide for free
creation and reading of PDF files. Some of the options available for the users
are LibreOffice, WordPerfect 9, Scribus, Adobe InDesign, Adobe Illustrator,
Google Docs, the pdfTe typesetting system, Ghostscript, etc.
Processors known as
Raster Image Processors (RIPs) are used in the conversion of PDF files into
raster image format. A raster format makes imaging suitable for paper, printer,
presses, etc. The whole process is called rasterisation.
As far as editing of
PDF files is concerned, there are a few software available in the market that
provides this facility. A little problem with this software is that they are
comparatively expensive. Some of such software are Inkscape, SerifPagePlus,
Enfocus PitSop Pro, Dochub, etc. This software are limited in number so users
have little choices to choose from.
Annotation is a
popular feature commonly found in developed PDF softwares, like Adobe. Adobe is
one example that facilitates a user to highlight, annotate, and add notes on
the PDF documents. Another software is XJournal that allows users to annotate
and highlight in different colors and shades, adding interactive features to
its software. It also allows features for underlining the text.
What is interesting
about annotations in XJournal is that they can be moved, copied, or pasted.
Then we have Freeware Foxit Reader, which allows annotations and is available
for Microsoft Windows, OS X, and Linux. Another software is Qiqqa, which offers
a summary of annotations made in the PDF document.
There are also
softwares available for annotations in PDF documents saved in mobiles. Some of
these softwares are iAnnotatePDF, GoodReader, etc. These provide the ease of
annotation as well as summary reporting of annotations done throughout the PDF
document.
There is PDF software
that available online like on the website Scribd for the purposes of viewing
and storage; Zamzar, which is another website that hosts PDF software for the
conversion of files into the PDF format; Pdfvue is another website that uses
PDF software to allow editing of the PDF documents online.

forces for its protection from outside attacks. The composition and character
of these forces differ from one planet to another, primarily because of the distinct
cultural norms existing in every one of these planets.
The military skills
and weaponry strength of the PDFs depend upon the overall performance of the
planet in the game. It is upon the government of each planet to oversee the
training of corps and implementation of improvement measures in their
