Adobe Reader is a computer program developed by Adobe Systems ("the parent" of the PDF file format) that allows the viewing of PDF files. It is available from the Adobe web site and it can be used free of charge.
The owner of a website(s) that chooses to promote a owner’s products and/or services. Affiliates agree to place owner’s promotions on their website(s) in the form of graphic banners or text links for the purpose of selling a owner’s goods and/or services. In return, the affiliate(s) earns a commission, which vary by merchant (e.g. for novaPDF the affiliate commission is up to 40% (or more), a very big commission considering that the normal one is 20%), on click-through’s, leads, or purchases made through the links on their site(s).
The percentage paid by a merchant to their affiliates for the promoting services performed. Usually a percentage of the sale price (normally around 20%), however other methods of determining the amount of money are frequently used, depending on the affiliate program used (pay-per-action, pay-per-performance, pay-per-lead, pay-per-click etc.).
Partnership under which owners of one website (for instance, a website about PDF software) send users to another website (such as novapdf.com) to purchase related items (the software product in this case, novaPDF). The owner of the target site shares its profits from the sales with the owner of the referring site.
A bug is an error in a computer program that affects it from working properly or returns an incorrect result. Bugs appear as a result of a mistake or error made by the software developers either in designing the application’s interface or in defining the proper algorithms used by the program. One of the final steps in writing a computer application is to debug it, meaning searching and repairing any errors that appear in the test phase. If bugs are discovered after the launch of the program, these are usually corrected by releasing an update, patch, or fix for that application.
Click-through is generated when a visitor clicks on an advertiser’s banner/graphic ad in order to visit the advertiser’s website. A click-through is often calculated (before the advertising placement is sold) as a percentage of page impressions. For example, if 1,000 Internet users view an advertiser’s message, and 10 click on the message to view the advertiser’s information, the click-through rate is 1%. This click-through rate is also referred as CTR (rates can vary a lot, from 1-2% to more than 10%).
Co-branding often means two Web sites or Web site sections or software application displaying their logos (and thus their brands) together so that the viewer considers the site or feature to be a joint enterprise.
The conversion ratio is determined by dividing the number of sales or leads generated as a result of an action (click-through on a banner/link, downloads, phone promotion etc.) and the number of actions performed. For example, having 100 downloads for an application and only one sale, means a conversion ratio of 1%. In this case, the higher the better.
Application made according to the specifications of an individual. This doesn’t mean that the entire application is re-written, it rather means that the program contains extra features or its design is changed according to the requests.
Encryption is the process of converting viewable data into "unviewable code" so that unauthorized people cannot understand the content. Encryption may be used to store private data (documents) in a secure manner(e.g., encrypting the data from an office hard drive), or to allow secure document sharing. Encryption is sometimes described as the process of transforming plain text into "ciphered text". To decrypt the message, the receiver of the encrypted document must have the proper decryption key. There are different types of encryption, depending on the size of the key used for encryption (both methods presented below are supported by novaPDF): 40-bit encryption is a key size for symmetric encryption representing a low-level of security where the key is forty bits in length. 40-bits can represent a total of possible keys. Although this is a large number (about a trillion possible combinations), it is possible to break documents using this encryption method by utilizing high computing power in a brute force attack (trying out each possible key in turn). 128-bit encryption provides a significantly greater amount of cryptographic protection than 40-bit encryption. In terms of what the numbers represent, "128" and "40" bit encryption refer to the size of the key used to encrypt the message. Roughly speaking, 128-bit encryption is 309,485,009,821,345,068,724,781,056 times stronger than 40-bit encryption. Presently, 40-bit encryption is not considered "strong" security in the cryptographic community. However, even taking into account Moore’s Law (computing power that doubles about every 18 months), 128-bit encryption represents a very strong method of encryption not only for now, but for the future too.
This is an option in various applications that allows the fonts used in the creation of a document to be included in that document, ensuring that a user will see the documents exactly as the creator intended them to be seen. Font embedding in PDF documents is one of the features supported by novaPDF too.
Ghostscript is a computer program based on the interpreter of the Adobe PostScript and the PDF page description languages. It used by some PDF creators as a file format converter (among others), such as PostScript to PDF converter, in order to generate the PDF files. novaPDF does not use GhostScript thus users don’t have to download and install additional programs to generate their PDF files.
A compression method that uses a specific algorithm to remove repetitive data within a image or video file in order to decrease the size of the resulting file. JPEG compression allows different levels of compression resulting in different file sizes with different quality levels. It can compress about 20:1 before image quality significantly deteriorates. novaPDF uses JPEG compression to decrease the size of a PDF file that contains images (if a user chooses to use compression).
OpenType is a computer font format initially developed by Microsoft, later joined by Adobe Systems that uses the general structure of a TrueType font, but adds some important features, like for instance the encoding based on Unicode (supporting this way any language). As of late 2004, there are over 6,000 fonts available in OpenType format. novaPDF supports OpenType fonts too, being able this way to generate pdf files from documents written in any language.
Also known as Page impressions or simply Impressions, represents the estimated number of visited pages within a Web site. For example, if a Web site contains 10 pages and an estimated 100 unique visitors per month that visit each page of the website, the site receives approximately 1000 monthly page views (10X100=1000).
A voluntary agreement between two or more competent persons to place their money, effects, labor and skill, or some or all of them, in lawful commerce or business with the understanding that there shall be a proportional sharing of the profits and losses.
Acronym for Portable Document Format. PDF is the de-facto standard for the secure and reliable distribution and exchange of electronic documents around the world. PDF is a universal file format that preserves the fonts, images, graphics, and layout of any source document, regardless of the application and platform used to create it. Adobe PDF files are compact and complete, and can be shared, viewed, edited, annotated and printed by anyone with PDF related software. One of the most known viewer/reader of PDF files is Adobe Reader (free). To create pdf files additional software is required, such as novaPDF, a PDF printer driver.
Converting a document from its original format to a PDF file using novaPDF. The term "print" is used to specify the fact that the conversion is done by selecting the File->Print option from the original application and choosing novaPDF as the printer. The resulting file will be a PDF document.
A program installed on a computer that serves as the communication link between applications and printers. It controls printing and sets options such as print quality and paper size for a particular printer. A PDF printer driver allows users to print directly to a PDF file instead of printing to a printer. For example, using novaPDF, when a user will give the command "Print" from any Windows compatible application, a PDF file will be generated instead of physically printing the content on paper using a standard printer.
RAR is a proprietary file format for data compression and archiving developed by Eugene Roshal (this is where RAR name comes from too, Roshal ARchive) and the native format of the very popular WinRAR archiver. We provide novaPDF in a .rar format as a mirror download.
SDK is an acronym for Software Development Kit, a set of development tools that allows a software developer to create programs (for a certain software and/or hardware platform, computer system, operating system) or to include a certain functionality in an existing application. For example the novaPDF SDK allows developers to include in their programs the ability to generate PDF files.
A font standard developed by Apple. The TrueType fonts are represented as geometric shapes and can be easily scaled to many different sizes and still maintain quality. An advantage of TrueType fonts is that they can be drawn in low-resolution on a monitor while still printing smooth characters on a printer. novaPDF has support for TrueType fonts.
A type of compression that decreases the total size of a file and allows larger amounts of data to be stored in fewer bytes. novaPDF uses ZIP compression to decrease the size of a PDF file that contains text (if a user chooses to use compression).
