NFTS,exfs2,extfs3 - Article Example NTFS, on the other hand, is very useful in the event where file systems are needed in sharing files with newer Windows systems. Journaling improves data integrity and recovery, especially after unclean system shutdowns. This avoids file system checks which take so long during the next reboot following an unintended shutdown. This is because the changes that occurred since the most recent write to disk are saved and ready to be restored. Journaled file systems guarantee fast crash recovery. The journaled file system also makes it faster to scan a partition and restore a system once the system has failed, unlike non-journaled file systems that take so long. Journaled file system also ensures better performance. A journaled file system is faster due to its codes that are highly optimized (Negus & Caen, 2008). Journaled file systems are usually slower than other file systems. The slowdown is a result of the many operations that have to be performed on the journal every time there is a file system change (EMC Education Services, 2012). Journaled file systems such as Ext.3 have become important especially in Linux distributions, and knowledge of the file system is applied in recovering evidence such as deleted files and file activity. A forensic investigator will, therefore, use the first mode, called the journal to obtain the information pertaining to the activity of the file system. This facilitates the recovery of file content, with an added advantage of recovering metadata activity on the file system (Easttom, 2011). In conclusion, journaling of file systems has proved to offer more advantages, thus the suitability in forensics and investigations. Its suitability in the restoration of systems after unintended shutdowns has been a great

Community and public health nursing - Case Study Example Apparently, the prevalence rates increases with age where U.S children aged between 15 and 17 years recorded the highest prevalence rate of 16.5 %. However, the highest prevalence rate in DC manifests among children aged between 5 and 9 years who had 21.6 %. Subject to these prevalence rates, I would target U.S children in the age group 15-17 for intervention since the condition is most common in this age group. The age group has the highest prevalence percent, 16.5 % in U.S. In DC, I would target children in the age group 5-9 for intervention. The age group has the highest prevalence percent, 21.6 % in DC. These interventions will reduce Asthma mortality rate among children. Moreover, subject to these prevalence rates, I would target black children in America and DC for intervention since the condition is most common in this race. The race has the highest prevalence percent, 21.0 % in U.S, and 20.4 % in DC. Indeed, the prevalence rate is higher among African Americans compared to whites and others. The intervention will reduce Asthma mortality rate among black
