Transcript

  • 1. By: Esteban Muñeton, Camilo Pacini, David Silva y Freddy Cabrera. Colegio Britanico 11b
  • 2. Content. Introduction. Objective. Development of the topic. Conclusion. References.
  • 3. Introduction On this presentation we´re going to talk about the data security and data transfer, and why is it important to know about it. Then we will talk about the different types of data file types, translating between file types, standard file types and rapid transfer of data.
  • 4. Objective. To understand better about data security and data transfer. To know about more about translating between file types. And to have a clear idea about Standard File Types and Rapid Transfer of Data.
  • 5. Data Security. Data Security means protecting a database from destructive forces and the unwanted actions of unauthorized users.
  • 6. Data Transfer Data transmission, digital transmission, or digital communications is the physical transfer of data (a digital bit stream) over a point-to-point or point-to- multipoint communication channel. Examples of such channels are copper wires, optical fibres, wireless communication channels, and storage media. The data are represented as an electromagnetic signal, such as an electrical voltage, radiowave, microwave, or infrared signal.
  • 7. Data File Types Quake 3 archive (.pk3) – (See note on Doom³) Doom³ archive (.pk4) – (Opens similarly to a zip archive.) RAR Rar Archive (.rar) – for multiple file archive (rar to .r01-.r99 to s01 and so on) RAG / RAGS game file, a game playable in the RAGS game-engine, a free program which both allows people to create games, and play games, games created have the file format "RAG game file" SEN Scifer Archive (.sen) – Scifer Internal Archive Type sit/sitx – StuffIt (Macintosh) SKB – Google Sketchup Backup File tar .tar.gz, .tgz – gzipped tar file TB (.tb) – Tabbery Virtual Desktop Tab file TIB (.tib) – Acronis True Image backup uha – Ultra High Archive Compression VIV – Archive format used to compress data for several video games, including Need For Speed: High Stakes. VOL – unknown archive VSA – Altiris Virtual Software Archive WAX – Wavexpress – A ZIP alternative optimized for packages containing video, allowing multiple packaged files to be all-or-none delivered with near-instantaneous unpacking via NTFS file system manipulation. Z – Unix compress file zoo zip
  • 8.  .?Q? – files compressed by the SQ program. 7z – 7-Zip compressed file AAC- Advanced Audio Coding ace – ACE compressed file ALZ – ALZip compressed file APK – Applications installable on Android AT3 – Sonys UMD Data compression .bke – BackupEarth.com Data compression ARC ARJ – ARJ compressed file BA – Scifer Archive (.ba), Scifer External Archive Type big – Special file compression format used by Electronic Arts for compressing the data for many of EAs games BIK (.bik) – Bink Video file. A video compression system developed by RAD Game Tools BKF (.bkf) – Microsoft backup created by NTBACKUP.EXE bzip2 – (.bz2) bmp – (paint) c4 – JEDMICS image files, a DOD system cab – Microsoft Cabinet cals – JEDMICS image files, a DOD system cpt/sea – Compact Pro (Macintosh) DAA – Closed-format, Windows-only compressed disk image deb – Debian Linux install package DMG – an Apple compressed/encrypted format DDZ-file, a file which can only be used by the "daydreamer engine" created by "fever-dreamer", a program similar to RAGS, its mainly used to make somewhat short games.
  • 9.  EEA – An encrypted CAB, ostensibly for protecting email attachments .egg – Alzip Egg Edition compressed file EGT (.egt) – EGT Universal Document also used to create compressed cabinet files replaces .ecab ECAB (.ECAB, .ezip) – EGT Compressed Folder used in advanced systems to compress entire system folders, replaced by EGT Universal Document ESS (.ess) – EGT SmartSense File, detects files compressed using the EGT compression system. GHO (.gho, .ghs) – Norton Ghost gzip (.gz) – Compressed file IPG (.ipg) – Format in which Apple Inc. packages their iPod games. can be extracted through Winrar jar – ZIP file with manifest for use with Java applications. LBR – Library file LQR – LBR Library file compressed by the SQ program. LHA (.lzh) – Lempel, Ziv, Huffman lzip (.lz) – Compressed file lzo lzma LZX (algorithm) MBRWizard archive (.mbw) MPQ Archives (.mpq) – Used by Blizzard games MacBinary (.bin) NTH (.nth) – Nokia Theme Used by Nokia Series 40 Cellphones PAK – Enhanced type of .ARC archive Parchive (.par, .par2)
  • 10. Translating between file Types Data conversion is the conversion of computer data from one format to another. Throughout a computer environment, data is encoded in a variety of ways.
  • 11. Standard File Types The need to import and export data files has led to the development of several standard file types that many applications can understand. Examples are jpg andgif files for images, and mp3 files for sound; but there are also standard file types for text, movies, and spreadsheet data. Often an application of a different type can import data, for example, a word processor may be able to import a spreadsheet file.
  • 12. Rapid Transfer of Data Files can be easily transferred and shared across the globe using the Internet. A file could be: emailed as an attachment sent over instant messenger downloaded from a website/web server accessed over a private network Documents, eg a spreadsheet, can be stored on a web server and then accessed via any computer with an Internet connection and a web browser. Collaborative working is possible too, where multiple people contribute to the same document.
