Question
1) USB 3.0. What are some of the improvements to USB 3.0? Find some devices that will benefit greatly from those improvements (that is to say, if you are going to buy that device, it is better to buy the USB 3.0 version than the USB 2.0 version, even though the 3.0 will be more expensive). Explain your answer (why the benefits of the 3.0 features outweigh the additional cost). 2) Biometric. What are some of the biometric devices in use today? Do you think they are effective in securing your computing environment? What are some of the down sides of using Biometric? Is there a way to bypass the Device (in other words, is there a backdoor to the system)?Explanation / Answer
situations are USB drives. They're small and speedier than other methods, and are compatible with nearly every computing device. There are problems with USB, those of which hopefully improve with USB 3.0. The final specs of 3.0 have been announced , and with them, products which look to expand the market. The first thing you should know about USB 3.0 is that in technical terms, it's called: SuperSpeed USB. I think that sounds silly though, and while I can appreciate wanting to differentiate it from 2.0 -- doesn't 3.0 do good enough job with that? I have a feeling that less tech savvy crowds will be confused by the new terminology and will be left with many unnecessary questions going forward. Since storage capacity is something which continually grows, whether or not a device is 2.0 or 3.0 doesn't matter. So, you can throw out notions that USB 3.0 will bring about a great boon in storage capacity. Instead, the largest improvement found with 3.0 is transfer speeds. While USB storage isn't the slowest method of transferring data to a portable source, it is far from the fastest. With USB 3.0 this looks to change with a 10x improvement in bandwidth. USB 2.0 models had maximum speeds of 480Mbps, while the 3.0 will see speeds of 4.8Gbps. Biometrics allow people to be identified based on unique characteristics. Examples include fingerprint scans, iris scans, and voice recognition. Biometric devices utilize technology to capture and process this type of information. Such devices may be found at airports, government buildings, and law enforcement agencies. Biometric devices normally capture information about a person the first time she uses it. That information is linked to her and other information may be linked it, creating a file. For example, a person may need to enter a premises that grants access upon fingerprint verification. The first time, the person’s fingerprint will be recorded and attached to her name and photo. It is also possible that other information, such as the make, model, and registration number of her vehicle, can be linked to that fingerprint. The two primary uses for biometric devices are identification and verification. These may sound as if they are the same but they can actually be very different. A facial recognition device may be used to identify a person who enters a building and is granted an access pass. The captured information may only be useful thereafter if it is necessary to identify who the access pass was given to. If that person ever returns, he may be subjected to the same process again.
