In todays world, where businesses depend on technology, saving information and other important data has become a very serious concern. Because personal information of clients and companys valuable data are kept within their computers, hosting an online data backup has become a successful and profitable business.Online data backup services work because they provide businesses with a way to save all their important information. This is accomplished by uploading the data via the Internet into a secured, online database. Because of this, businesses will never have to worry about loss of information, struggle with backup software, or lose money when their database of clients is erased.Due to the popularity of this simple concept, and the development of numerous companies hosting online data backup, it is important to consider several factors before choosing a company to host your data. For instance, ask about the companys security in terms of their offsite storage, time required to upload and backup information, and duration of storage and restoration before inquiring about service charges.Choosing an Online Data Backup CompanySmall businesses often benefit from online data backup services because they dont have the money hire people to backup their data every day. Although backing up your data online may be an effective solution to store important information, it is important to understand that of all the hundreds of companies offering online data backup, half of them provide excellent services, while the other half should be avoided.In terms of performance, be aware that several factors will influence how well a company can upload and store your data. These include your internet connection, number and size of the data that you need to backup, duration of uploading and restoring, as well as the technology used by the online data backup provider. For this reason, it is a good idea to ask the company how long it would take for you to backup and restore a certain amount of data, for instance, two or five gigabytes.The items you wish to backup will affect the duration of uploading and restoring. Some companies only backup their documents from the main server once a week. If this is your case, it will only take a few minutes to backup. However, if you want to backup all your servers, workstations and databases every day, then you will spend more time in the backup process. In this instance, you should ask the provider about the protection or security of their online data backup services.Costs of online data backup services will vary depending on your preferences, such as the amount of data to backup, the level of performance you require, the services you select and other packages you wish to subscribe to.

By now, you've likely heard about this hot new technology called GPS. Handheld GPS receivers are popular items that are being used by everyone from outdoors enthusiasts to average drivers. But, how many of us really understand the technology behind these modern-day marvels?There is a whole lot of power and capability packed into a GPS receiver. They are linked to complex satellite systems in outer space, providing a reliable navigational system to users on earth. Many new cars have GPS receivers included as standard equipment. Hikers use them to find their destinations, and treasure hunters rely on them for Geocaching excursions.Simply, a GPS is an electronic device that can determine one's precise location on earth. The entire system is anything but simple; and the GPS receiver is but a single and minute part of this immense network. GPS is the short form of Global Positioning System. This very large navigation system was developed and implemented by the United States' Department of Defense (DOD). The system is composed of a network of 27 satellites, various ground stations located at points throughout the world and individual GPS receivers. Most of the 27 satellites in the GPS are active, and continuously send radio signals. GPS receivers use these signals to determine their geographical location.FunctionThe primary function of a GPS receiver is to pinpoint its actual location on earth using the signals it intercepts from GPS satellites. To do this, the GPS receiver must be able to locate and intercept signals from three or more GPS satellites. After intercepting the signals, GPS receivers use basic principles of mathematics called triangulation or trilateration to compute its actual position. Before any triangulation calculation can be implemented, however, the GPS receiver must verify two points:1- The positions of at least 3 satellites2- The distance between each satellite and the receiver.GPS receivers decode the signals in order to determine the locations of at least three GPS satellites. The signals transmitted by GPS satellites are radio signals, and each contains three different bits of information: ephemeris data, almanac data and a pseudorandom code. The ephemeris data is the information that the GPS receiver needs to be able to determine the actual position of the satellite transmitting the signal.The distance of a GPS receiver to a satellite is measured using the signal's speed, or the time delay from the initial transmission of the signal, to its reception by the GPS. From this speed or time difference, the GPS receiver calculates the satellite's distance.With information about the location of at least three or four satellites, along with their individual distances, a GPS receiver utilizes the basic principle of triangulation to calculate its actual position in terms of altitude, latitude and longitude.AccuracyGPS receivers are incredibly accurate, usually to within twenty meters of radius. It is possible, however, to increase this accuracy level using supplemental technologies. Some GPS receivers using multiple parallel channels can achieve an accuracy level to within fifteen meters. More complex systems such as DGPS (Differential GPS) and WAAS (Wide Area Augmentation System) can reduce this range to an impressive three meters.Despite the use of these supplemental technologies, there are still many factors that can cause even the best GPS receivers to broadcast inaccurate locations. Among these factors are:* Number of visible satellites* Radio signal delays caused by the passage through the ionosphere and troposphere* Signal multipath (bouncing of the signal as it hits an object)* Inaccuracy of GPS receiver clocks* Ephemeris errors (inaccuracy of the satellites' reported locations)* Poor positioning of satellites (i.e.: satellites in a linear position, or in a tight grouping)Some, but not all, of the GPS errors caused by these factors can be remedied by the software that is packaged with personal GPS receivers. If you are having difficulty with the accuracy of your GPS receiver, check your user guide or refer to the software to see if the problem can be fixed.Technology has given us wonderful gifts and powers beyond imagination. A GPS receiver is one technological wonder that is so accessible, many people use them on a daily basis. If you travel locally or across country, or enjoy exploring the great outdoors, pick up a GPS receiver and you'll always be able to find your way home.
DRM stands for Digital Rights Management, or as some people call it, Digital Restrictions Management. Put simply, DRM consists of various restrictions applied in music or video files, so their use (such as playback) can be controlled by a third party, usually the company holding the copyright for a song or movie. DRM is not just a copyright protection technique but a whole set of technologies that aim to implement the DRM strategy each distributor of digital content specifies. As an example, DRM can verify that the user that bought an audio file is actually the same user playing the file. DRM technology can also be used to limit the number of PCs a file can be played on. The major disadvantage of DRM is that these restrictions are not always clear when a user buys a digital product.Which Multimedia Formats Support DRM?If you're expecting to see MP3 in this list, guess again. Due to it's open nature, the MP3 standard is unable to support DRM. Furthermore, there is no centralized coordination in the development and evolution of the MP3 format so don't expect digital music stores to offer songs in the MP3 format.Advanced Audio Coding: The AAC format, used by iTunes and iPod, is based on Apple's QuickTime. It was originally designed as a replacement of the MP3, and can actually compress files better than the MP3 format can.Windows Media Audio: WMA is a closed-source standard of digital music. It was designed to compete with the MP3 but in reality, it's actually AAC's main competitor, especially with regards to DRM support and buying music online. The latest version of WMA offers similar quality to that of AAC and better than that of MP3 files. This means that much smaller files can have CD quality. WMA is based on the ADvanced System Format (ASF) which can integrate different streams of audio and video as long as they belong to the Windows Media family.RealNetworks & Sony: Both of these companies offer music download services. Real mostly uses the AAC format with the Helix DRM system, while Sony uses the OpenMG DRM system on ATRAC3 files. It is expected that Sony will support other music formats in the future.Limitations of iTunes and iPodFinally, here are certain things that you should know about iTunes DRM:1. Music you buy from iTunes can only be played on an iPod.2. Files from iTunes can be played on an unlimited number of iPods.3. iTunes allows you to download each song you buy only once and of course, you're not allowed to re-sell that song.4. An iPod can also store and play non-DRM music files.5. Any certified .m4p files can only be copied/played on 5 authorized computers.6. Music you buy from iTunes can be copied to a CD without any DRM limitations.7. A playlist consisting of songs you bought from iTunes can only be turned into a CD 7 times (you can make 7 CD copies of the list).8. You are not allowed to convert a song to a different music format.
A Type Library is a software file that describes software interfaces in an operating system, typically Windows. It also describes co-classes, and other resources in a Common Object Model server. A type library file created by Visual Basic will always have a .TLB extension. The .TLB file is required by a client to connect to a server.A type library can be thought of as a binary version of an IDL (interface Definition Language) file. Visual basic creates a type library when you create a VB server object, thus eliminating the need for an IDL file. A C-like language used to define interfaces and co-classes for COM. Ole View is a COM utility that reverse-engineers a type library into a readable form of IDL. IDL is used to provide language-independence for COM interfaces so that identical interfaces defined in VB, C++, and Java look the same in IDL even though they look different in the language used for implementation.Other Types of Type LibraryThere is also the type library in the system that is used to display the type or font on the screen and printed document. This type or font library is located in the systems registry. Every time a program calls upon the type library top to display the font, the type library looks up the registry to locate the type that has to be displayed. If the type is not present in the library the page displays the default of the closest matching font for that type.So What Is The System Registry?The operating system must have the knowledge as to where to find certain files when the programs call on them for some function. This information was initially stored in the information folder denoted as INF in earlier versions of Windows primarily 95 and 98 first edition. Microsoft introduced the registry in windows 98 Second Edition to speed things up while loading and locating programs. But this can also slow the system down drastically. This Registry is a database used to store settings and options for the 32 bit versions of Microsoft Windows including Windows ME and NT/2000. The Registry contains information and settings for all the hardware, software, users, and preferences of the PC. This registry is constantly growing and updating itself. There will come a time when it will need to be cleaned. This can be done with one of the free XP registry cleaner if you are using XP or any other Microsoft free "registry cleaner" .The physical files that make up the registry are stored differently depending on your version of Windows; under Windows 95 & 98 it is contained in two hidden files in your Windows directory, called USER.DAT and SYSTEM.DAT, for Windows Me there is an additional CLASSES.DAT file, while under Windows NT/2000 the files are contained separately in the SystemRootSystem32Config directory. You cannot edit these files directly, you must use a tool commonly known as a registry cleaner to make any changes in the Registry. It is in fact, advisable never to fool around with the Registry unless you have a trusted registry windows cleaner such as the PC registry cleaner or the Eusing free Registry cleaner which are available on many download sites free.
