Antibiotics and disinfectants are both used to kill and prevent the growth of bacteria. Antibiotics come from the fungi family and are commonly used to kill bacteria. While each antibiotic works differently for particular bacterias, all of them either target physiological pathways to enable the disruption and killing of bacteria or it inhibits of cell growth ((of prokaryotic cells)). The physiological pathways are genetic and biochemical (act in converting to mediate bacterial response to an…

1. Maintains an exact replica of one disk on another offering 100% fault tolerance. 2. Data redundancy - If one disk fails, data can be recovered from the other. 3. Fault tolerance - Even when one disk fails, the other one can continue functioning and the system continues to function. 4. Quick recreating data when a disk is replaced 1. Reduced data storage capacity a Raid 1 disks capacity is half the physical disk capacity. 2. Raid 1 is slower as it does not improve read or write speeds. 1.…

can be hidden in the form of images. They also discussed the terrifying prospect that information that you believe to have been erased may in fact be lurking somewhere on your disk. We cannot possibly see all the information stored on our computers. In fact, normally we don’t need to know all the hidden information. However, when sending redacted messages it is important to make sure that the information that…

Ultrasound Technicians, also known as diagnostic medical sonographers, use equipment that makes sound waves to produce or record a picture of the internal organs. Sonography is an important medical field because it allows technicians and physicians to see and diagnose a patient’s condition in a minimally intrusive way. What once may have required exploratory surgery now is a quick outpatient procedure with minimal patient discomfort. Ultrasound works by using a high rate of sound waves and…

Sound Card - This component provides audio signals, both input and output, of a compute program; it is typically attached to the motherboard via the PCI bus. Internal Optical Disk Drive (ODD) - A slot to insert optical disks, which will then write or read data to or from the disks. Solid State Drive (SSD) - A form of hardware that stores data persistently on flash memory chips, which is roughly 500 times faster at storing and retrieving data than the magnetic storage method…

Fluoroscope, is an x-ray device that allows physicians to view live images inside the human body that are projected onto a viewing monitor during a diagnostic and intraoperative procedures. This machine uses X-rays to give real-time video images on the area of interest making it possible to see internal organs in motion such as blood flow and catheter insertion. A Fluoroscopy captures these X-rays with a device called an image intensifier and converts the X-rays into light. The light is soon…

A long time ago (3.9 billion years to be exact) in a galaxy far, far away, a deadly black hole ripped a star to pieces. In 2011, evidence of this was finally detected by NASA's Swift satellite. Within days, scientists around the world were able to identify the cause of the outburst. While their description has more to do with tidal disruption, one never knows when evil aliens could be to blame. NASA HOPES TO UNDERSTAND VIOLENT BLACK HOLE NASA doesn't quite understand what caused the X-ray…

Case Study #3 The main goal of a computer forensic investigator is to conduct investigations through the application of evidence gathered from digital data. As a forensic investigator, it’s important to have a strong understanding of the different types of evidence that maybe encountered and the appropriate steps for retrieving and preserving it. The information that is collected during an investigation is extremely fragile and must be properly processed. In order to accomplish this, forensic…

suspect’s disk then both the string of character and the string from the cloning drive must match and if the match this produces an exact bit-by-bit match.(Knetzger&Muraski,2008). Here’s an example of an MD5 valve for a single file; b017e028a96ca4fbb536e30f1cb834f8. The fourth concept Forensic Analysis is the process when all evidence is turned over to the forensic specialist who will then capture clones, recovers and analyzes all the data that has been seized from the suspect’s hard disk or any…

Safeback, Expert witness, & Snapback, & one of these tools will be used to complete a bit-stream backup that will be performed on the device. Once the drive is backed up, the drive information will then be saved on write optical disks & began a case file. Two back up disks will be created for in case something were to happen to one of them. Sometimes it can be difficult completing the backups due to the age of the system, format of the drive, double spaced, & new high capacity devices, & if the…
