Computer Forensics - Portfolio - Case Study Example Digital evidences are regarded as different types of electronic information and are considered as vital proofs for evaluating any criminal incidence. This type of information is stored, received and shared by electronic devices. Digital evidences can exist in several formats such as text, graphics, audio and video among others. The digital evidence has been acquired when the electronic devices are seized. The digital evidence that has been found in the crime scene was WDD hard disk, USB flash drive, compact disk (CDs) and central processing units (CPUs) (see fig 1). Hard Disk. Hard disk is basically a read/write storage media which is used for collecting, storing, retrieving and accessing information. It is regarded as vital source of proof for the crime because the system files and other operating files are stored in hard disk. Hence, in order to investigate the crime conducted by Mr. Didit, the hard disk has been sized (see fig 2), as it probably provide certain valuable proof (Mukasey et al., 2008). CD. CD is regarded as the other important digital information source. It is basically a replicate of the original information and is used as permanent storage media. Thus, the information in CD is believed to be of highly important for Mr. Didit to be stored and thus, has been acquired for the purpose of digital evidence (see fig b3) (Mukasey et al., 2008). USB Flash Drive. USB flash drive is a small portable and high capacity electronic storage media. Unlike hard disk, USB drives connect to the computer through Universal Serial Bus port. USB flash drive has gained much popularity because of its storage capability and rapid access of data. The USB flash drive can also store information regarding any works and therefore regarded as valuable evidence for this criminal case (Mukasey et al., 2008). CPU. CPU is a case that contains electronic elements such as memory, processor and hard drive among

CLIMATE CHANGE AN OUTCOME OF ANTHROPOGENIC FACTORS Essay

CLIMATE CHANGE AN OUTCOME OF ANTHROPOGENIC FACTORS - Essay Example The Intergovernmental panel on climate change at the Kyoto protocol determined in 2007 that â€Å"most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations† [2]. Furthermore, based on the assumption that significant anthropogenic warming has taken place over the past 50 years over each continent except Antartica, it has been concluded that anthropogenic climate change is having a significant impact on physical and bilogical systems globally [3]. Climate change is occuring on all continents and in most oceans. Changes in the natural system since 1970 have been occuring where temperature increase has taken place. These changes cannot be explained by natural climate variations alone. This implies that climate change is primarily attributable to anthropogenic factors. The Intergovernmental Panel on Climate Change (IPCC) conclude that the earth is warming and tha t humans are probably the cause. Technologies to decrease greenhouse gas emissions and strategies for carbon sequestraion have been found to be essential as species extinction has been found to be related to climate warming [4].
