Journaling File Systems due: Journaling File Systems Journaling file systems areinspired by techniques applied in the design of a database that preserve database consistency. In a journaling file system, the storage device is treated as an unbound linear array of blocks. In the array of blocks, a journal is kept that records information about every update to the file system. The update information is sufficient for replaying each update, and ensures that the update is complete resulting in a consistent file system. File system such as ext3 contains journaling features which guarantee the safety of data after unexpected shutdowns. NTFS, on the other hand, is very useful in the event where file systems are needed in sharing files with newer Windows systems.
Advantages of journaling
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).
Disadvantages
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).
Application in forensics
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 success.

Identify the Impact of Pathophysiology, Psychology and Sociology in Determining the Physical and Mental Health Status of the Ind

...with cognitive, behavioural, social and emotional changes, Lucinda should receive psychological and social intervention to make her understand and be emotionally prepared for other serious physical and mental health changes as the Alzheimer’s diseases progresses to a more advance stage. To identify the presence of brain damage, either MRI or PET scan can be used. In general, the pathophysiology of Alzheimer’s disease is characterized by the presence of plaques and tangles in the brain. Common among the aging individuals, the presence of ?-amyloid plagues, neurofibrillary tangles (NFTs), and the neuronal cell death are among the main factors that can cause the patients to undergo a neurodegenerative process (Kumer et al.,...

Stage 2 shows symptoms like requiring assistance in performing daily tasks, forgetting recent happenings, mixing up distant past with recent past, having language problems, depression, insomnia and eating troubles. Stage 3 has symptoms like being unable to feed one, control bowel and urinary movements, speak, or recognize members of the family. Memory vanishes away (American Health Assistance Foundation, 2010). Objective Findings Objective findings include: Neurofibrillary tangles (NFTs) which are unusual clumps or tangles of a protein, known as tau, and are present within neurons...

Windows File Systems

...with the windows XP version of Microsoft windows (Carrier, 22). However, there is a contrast among theses file systems. To start with, while the FAT file system can be used with all versions of the Microsoft windows, it is not the case for the FAT 32 and the NFTS file systems. FAT 32-file system is limited to few versions of these windows such as windows95, windows 98, windows XP, and windows 2000. On the other hand, NFTS file system is limited to application with some versions of Microsoft windows such as windows XP, windows 2000 and windows 4NT, while applied with service pack 4 (Mendel, 54). Another contrast as depicted by theses file systems is that, the NFTS file system is more...

Pathological Processes in the CNS and the Rest of the Body

...on the frequency of islet amyloid. There is close resemlbace in pathology in the brain of a person suffering from alzheimer’s disease and that of a person suffering from Type 2 diabetes. The similarity is attributed to amyloid deposits with gradual reduction in the number of cells of proteins. Amyloid deposits are cytotoxic and may lead to disruption of protein cell membranes in both diseases. NFTs and Hyperphosphorylated Tau Protein Tau protein abnormalities is said to initiate the Alzheimer’s disease process. A hyperphosphorated tau pairs with other tau threads. Eventually, they form neurofibrillary tangles (NFT) inside nerve cell bodies (Julien, et al., 2010). This leads to disintegration of micro...

...neurodegenerative disorders (Gavett et al. 2011b). 3. Diagnosis The fundamental neuropathologic feature of CTE is the presence of sparse, moderate, or frequent band-shaped, flameshaped, small globose, and large globose NFTs in the brain accompanied by sparse, moderate, or frequent neuritic threads (NTs). For CTE diagnosis, the quantitative classification of NFT and NT topographic sparse, moderate, and frequent distribution are based on the CERAD plaque density scoring system.14 Ghost tangles may accompany NFTs and NTs in different regions of the brain. NFTs and NTs are differentially and topographically distributed in the neocortex, subcortical nuclei/ basal ganglia,...

The Pathophysiological Treatments of Alzheimer's Disease

...entity. Pathophysiology The core findings of the neuropathology of the disease have led to the discovery of certain changes in the extracellular amyloidal plaques, neuronal death, synaptic deterioration, and intracellular NFTs (Thies and Bleiler, 2011: 208). Upon the examination of tissues, it is easy to see the granulovacuolar degeneration in the patient’s hippocampus and the amyloidal deposition within the blood vessels. Research also revealed that the increased interference of synaptic activity by the amyloidal plaque initiates a series of downstream effects that lead to further increase in intraneuronal dysfunction, and this leads to the death of cells (Hardy, 2009: 1129). Pathological Mechanisms in AD One of the...
