المعلومات هي البيانات ذات معنى . و تحتاج المنظمة إلى المعلومات كي تتمكن من ربط أجزائها المختلفة لتحقيق أهدافها و حتى تتمكن من التكيف مع البيئة المحيطة بنجاح . و تكون المعلومات ذات قيمة للمنظمة كلما كانت فائدتها أكبر في اتخاذ القرارات و العمليات و هنا ك خمس صفات أساسية للمعلومات حتى تكون ذات قيمة للمنظمة و هي : ملاءمة المعلومات للتكنولوجيا المستخدمة في المنظمة، و دقة هذه المعلومات، و كميتها، و توقيتها، و سهولة الحصول عليها .
The process of transfer a speech signal by high confidentially and as quickly as possible through the Internet needs to develop compression and encryption technology for a speech signal, so as, to reduce its size and make it understandable to persons not authorized to listen to. A system was designed to encrypt the voice over Internet Protocol (VoIP) and use compression technique for the purpose of reducing the size of data and send it over the network, (A_law PCM) algorithm was used the to compress audio data. Then algorithms of Triple Data Encryption Standard (TDES) and Advanced. Encryption Standard (AES) were applied. A new encryption algorithm was proposed based in its work on the block cipher encryption system called the Direct and Reverse algorithm, which based on three basic steps, firstly expand the initial key, secondly direct the encryption of each round in one direction, and finally substitute (Bytes) as used in the Compensation Box in AES algorithm by making it moving. In general compression ratio was calculated and it was (50%) and the results of the correlation coefficient for the proposed algorithm was compared with the results of (AES, TDES) algorithms.
This research aims at the definition and importance of corporate governance including its principles, objectives, and their role in increasing the performance of state enterprises. As there is no agreement on the concept of governance, there is an ag reement that applying governance enhances the performance of an enterprise undertaking and its ability to face any financial crisis may be the importance of governance as an effective tool of control in the governmental corporations through several internal and external mechanisms.
