All about Adobe PDF

What Is a PDF?

Short for Portable Document Format, PDF is a file format developed by Adobe Systems. PDF captures formatting information from a variety of desktop publishing applications making it possible to send documents and have them appear on the recipient's monitor (or printer) as they were intended to be viewed. A properly prepared PDF will maintain the original fonts, images, graphics as well as the exact layout of the file. A PDF file can be shared, viewed, and printed by anyone using the free Adobe Reader software regardless of the operating system, original design application or fonts.
Originally PDF was mostly used by graphic artists, designers and publishers for producing color page proofs. With its evolving technology, however, today PDF is used for virtually any data that needs to be exchanged among applications and users. It is an open file format specification and PDF is available to anyone who wants to develop tools to create, view or manipulate PDF documents.

The Evolution of PDF

While the idea behind the format was tossed around as early as 1984, it wasn't until 1993 that Adobe launched its Acrobat 1.0 (and PDF 1.0) product line. Those first Acrobat products were touted as being "a PostScript-based file format that can describe documents in a completely device and resolution independent manner." Initially ideas of CD-based books and magazines surfaced. Imagine being able to walk into a bookstore and read a portion of a book on PDF before purchasing.
PDF and the Acrobat software was a new type of product that addressed some of the big problems in the publishing industry. PDF and Acrobat allowed you to send your document across networks (and different platforms) while preserving the fonts and document formatting. In 1993 bandwidth and bottlenecks were a huge issue (four years before the 28,800 kbps modem became the standard in fact), Acrobat products offered a way to transfer documents without having to attach multiple fonts. Additionally, the documents could be sent without designers needing to worry about application specific usage agreements.
With so much promise and industry buzz about this new format and associated products, it is surprising that Acrobat didn't take off like a rocket. Some industry watchers attribute its slower success to that fact that users needed to pay for the PDF reader, while others just didn't think outside the box and see the endless possibilities associated with PDF. In 1994 (with much ado), Adobe announced that its Acrobat Reader software would be available for free through online services and Internet server locations. In addition to an evolving distribution method, the products themselves evolved from simply allowing you to view and print a document to providing a way to extract specific selections of text or images from the file, password-protect areas of the document, and much more.
Over time Adobe's PDF format and Adobe Reader broke through its initial slump. Today Adobe PDF has achieved widespread use and is now a streamlined format for exchanging documents. It is now, in fact, the standard format for the electronic submission of drug approvals to the U.S. Food and Drug Administration (FDA) and for electronic case filings in U.S. federal courts. Over half-a-billion copies have been distributed since it's initial version 1.0 release.
From an initial set of three products in 1993, the Adobe Acrobat family of products has grown into an offering of nine products, designed to suit individuals as well as enterprise users who need to create, view, and share PDF files.

The Adobe Acrobat Family - All You Need to Create, Manipulate, and Read PDF

Adobe Reader

To view a file in PDF format, you need Adobe Reader, which is a free application distributed by Adobe Systems. The free reader allows you to share your PDF documents with anyone and allow the end user to view or print the document on any system. It's available for Windows, Mac, Unix, Linux, AIX, HP/UX and Solaris operating systems. Adobe Reader is also available for mobile devices running Palm OS, Pocket PC, or for Symbian OS. Users can freely download Adobe Reader from the Adobe Web site.

Adobe Acrobat & Adobe Elements

To create PDF files for distribution, you'll need to have Adobe Acrobat (available in Professional or standard versions). While specific features between these products differ, any will allow you to both create a PDF document from any application that prints and to manage specialized content from other applications. All three support Microsoft Office (while the Acrobat standard and Professional versions support additional applications). These products also allow you to protect documents with passwords and apply restrictions on printing, copying, and alterations. You can also use them to view, print, and search Adobe PDF files.

The standard version of Acrobat offers features such as support for applications like Microsoft Outlook, Internet Explorer, Access and Publisher. You can also digitally sign and certify documents, and Combine application files into a single Adobe PDF document. Naturally the Professional version of Adobe Acrobat offers even more features.  Some applications needed to design and create PDF files are available as free 30-day trial versions from the Adobe Web site.

Create Adobe PDF Online

This subscription-based offering allows you to create Adobe PDF Online. You can create and publish reports, spreadsheets and resumes for distribution. You can also archive Web sites for easy reference and research, or turn scanned paper documents into searchable Adobe PDF files. Create Adobe PDF Online offers a free trial where you can create your first five Adobe PDF files for free, after which the service is available through a monthly or yearly subscription fee.

Sharing, Serving & Dealing With Large Volumes

Adobe also offers products that can assist you in deploying PDF distribution across your network or enterprise. Some of these products include the following:

Adobe Acrobat Elements Server allows organizations to centrally deploy and manage Adobe PDF file creation capabilities across the enterprise.

Adobe Acrobat Distiller Server allows workgroups to convert Adobe PostScript files to compact, reliable and more secure Adobe Portable Document Format (PDF) files over a network.

Adobe Acrobat Messenger software is combined with a scanner or digital copier to transform paper documents into electronic files that you can deliver via e-mail, Web, fax and and so on.
Adobe Acrobat Capture software is a professional production tool that teams with your scanner to convert volumes of paper documents into searchable PDF files. Acrobat Capture is designed to provide accurate OCR, advanced page and content recognition, and powerful cleanup tools let you turn all your important paper-based information into electronic documents.

How PDF is Used Today

It is becoming increasingly easy to create PDF files as the process is almost as simple as printing. Essentially, anything that can be done with a sheet of paper can be done with a PDF. PDF technology is being used more frequently to produce offset printed documents.
Adding to mainstream adoption, of course, is the fact that many applications allow users to save, import or export a document as a PDF (including popular publishing programs like QuarkXPress and CorelDraw), and you can also find a variety of third-party PDF conversion software tools available. With the capability to embed metadata (data about data) in a PDF file, along with the use of security options and electronic signatures PDF is also becoming a standard for data archiving. It may have taken a few years to perfect — and years of dedication by the development team at Adobe, but today more and more people are turning to PDF as the solution for something not even thought of in 1993.

Did You Know... "In 1993 the initial Adobe Acrobat Product Line was composed of three different products: Acrobat Reader, Acrobat Exchange and Acrobat Distiller. At this time, these products were only available for a fee."

What is the Difference Between RAM and ROM?

RAM (Random Access Memory) and ROM (Read Only Memory) are types of computer memory that provide users with access to information stored on a computer. Here are the top five differences between the two types of memory:

RAM is Random Access Memory. 
ROM is Read Only Memory.
RAM is the memory available for the operating system, programs and processes to use when the computer is running.
ROM is the memory that comes with your computer that is pre-written to hold the instructions for booting-up the computer.
RAM requires a flow of electricity to retain data (e.g. the computer powered on).
ROM will retain data without the flow of electricity (e.g. when computer is powered off).
RAM is a type of volatile memory. Data in RAM is not permanently written. When you power off your computer the data stored in RAM is deleted.
ROM is a type of non- volatile memory. Data in ROM is permanently written and is not erased when you power off your computer.
There are different types of RAM, including DRAM (Dynamic Random Access Memory) and SRAM (Static Random Access Memory).
There are different types of ROM, including PROM (programmable read-only memory) that is manufactured as blank memory (e.g. a CD-ROM) and EPROM (erasable programmable read-only memory).
There are many differences between RAM and ROM memory but there are also a couple similarities (and these are very easy to remember).  Both types of memory used by a computer, and they are both required for your computer to operate properly and efficiently.

Windows 7 Blue Screen Problems and How To Fix This Error

The blue screen error — also known as Blue Screen of Death (BSOD) — is pretty common on all versions of Windows, be it the oldest or even the newest one. This error can get really annoying. It can even block users from logging onto their Windows operating system. As a result, the system is seemingly impossible to use at all. But what PC users should keep in mind is that they are not the only people to experience this particular problem. It has been pretty common and, fortunately, people have found out some workaround methods that may prove to be quite effective in solving the BSOD.

                     

BSOD Triggers

However, it is important to understand what may have triggered the BSOD. Most of the time, BSOD can be triggered by a recent change in either the computer’s hardware or software. For example, a newly installed hardware will most likely need proper driver files in order to work properly. Although it is true that the drivers are normally provided with the hardware, there are times when the driver files may happen to be corrupted. Another possibility is that one or more of the applications or software installed on the system encounters conflicts. Also, taking into accounts that drivers are software as well, they may just as well trigger the conflicts.

Yet, if the problem is not on the software, chances are there is something wrong with the hardware. It may have been damaged or installed improperly. In this case, it is always a good idea to try using the hardware in question on another computer to see if it works.

How to Solve BSOD

There are several ways that may well solve the blue screen error. The first way is to uninstall the drivers and try to install the latest drivers from the website of the hardware vendor. Secondly, it is worth trying to uninstall the device using the Device Manager utility. Last but not least, System Restore utility built into Windows may also be pretty helpful.

However, some people may wonder how they can run all these utilities if they cannot even log onto Windows. Well, the Safe Mode provided with each version of Windows is normally the answer to this. When the computer is trying to boot after passing the self diagnosis process, constantly hitting the F8 key will usually display a list of advanced Windows options, one of which is the Safe Mode. Choosing it will enable users to log onto the system yet with limited capabilities. However, it is enough to solve the BSOD.

                    


So, at this stage, it is possible to use any of the 3 possible methods mentioned earlier. The first is to uninstall the drivers. Yet, one thing that is important to keep in mind that Windows tends to leave junks behind after some things are uninstalled. Therefore, it may be necessary to launch the Registry Cleaners to clean up the rest of the troublesome drivers. Manual registry edition is not advisable for newbies because Windows Registry it`s such delicate thing that, you can easily damage Windows functionality if you’re not know what are you doing!

The second method is to uninstall the device using Device Management utility. This utility can be launched by typing “devmgmt.msc” in the command line. Once the utility window shows up, simply right click on the troublesome device and choose Uninstall.

Lastly, there is System Restore. However, this method won’t be useful unless this feature is kept active all the time. Some advanced PC users may disable it to save spaces and processing time of applications. System Restore can be accessed by clicking the Start button and then choosing Programs followed by Accessories and System Tools. Users simply need to choose a date before they install the new conflicting hardware or software and Windows will revert everything to that date. As a result, the operating system should now be working normally again.

1. Go to Start → Programs → Accessories → System Tools → System Restore
