Reliability+&+Integrity

= __RELIABILITY & INTEGRITY __ - By:Jonny Edmondson =

=Reliability= //ITGS Definition:// Reliability refers to the operation of hardware, the design of software, the accuracy of data or the correspondence of data with the real world. Data may be unreliable if it is entered incorrectly or if it becomes outdated. For example, a medical record that becomes dissociated from the patient it refers to becomes unreliable. The reliability of machines, software and data determines our confidence in their value.

__Un-Reliable Products:__

Recent news presents the famous Xbox 360 as an extremely un-relaible product. Despite the huge sales turnover and fan database that is associated with the Xbox many fans are left let down once again by the failure of Microsoft. Statistics show that over 33% of Xbox 360's nowadays are suffering from the infamous "Red Ring of Death" resulting in the death of their beloved Xbox. The "Red Ring of Death" is shown by a ring of red lights replacing the previous green lights on the Xbox, which basically means that the Xbox's motherboard has unfortunately snapped leading to no more gaming days for the player until the Xbox is replaced at their own expense. I ask myself the question why would people buy an Xbox when they could spend a little bit more money to buy a similar, yet supirior gaming sysyemcalled the PS3 which is evidently more reliable, as the ps3 has been on the market for just over 3 years now and is still today the only games console which has not been hacked.

**Integrity** //ITGS Definition:// Refers to safe guarding the accuracy and completeness of stored data. Data lacks integrity when it has been changed accidently or tampered with. Examples of data losing integrity are where information is duplicated in a relational database and only one copy is updated or where data entries have been maliciously altered.

__Breach of Inegrity:__

Jailbreaking is a process that allows iPad, iPhone and iPod Touch users to install homebrew applications on their devices by unlocking the operating system and allowing the user root access. Once jailbroken, iPhone users are able to download many extensions and themes previously unavailable through the App Store via unofficial installers such as Cydia. A jailbroken iPad, iPhone or iPod Touch is still able to use the App Store and iTunes. Data integrity is the assurance that information can only be accessed or modified by those authorized to do so, therefore the process of jailbreaking your Apple product is a breach of integrity as it allows the user to be able to access and modify files which should only be accessible to authorized personnel.
