Explain 2 solutions. all nov 28 kuni

The most common causes of data loss and downtime are hardware failure, power outage and software malfunction. One solution is to regularly back up data (daily) and make sure that the computer has a recovery system enabled. The second solution is to plug every computer into a UPS (uninterruptable power supply) in case of power outage.

The device is designed to absorb and feed on micro droplets of water. However if someone were to step in a large puddle of water the device could be over loaded and burnout. Also with the problem of how to transfer the energy a cable would work the best because if you use wifi or Bluetooth other devices could pick up that signal and steal the energy supply for their own use. A solution to the way power is generated it to do something similar to the Japanese train station and make the pad in the shoe absorb shockwaves from each step instead of the micro water molecules also if it were shock absorbent it could be but into a waterproof case so that it can withstand rain and puddles.

Agree Agree to some extent. Internet freedom can be sacrificed only to a certain extent to fight piracy. Getting rid of internet freedom is basically the same thing as shutting out the communication lines of the world. The source of the reason why piracy is done is mainly due to the fact that people can't afford the items that they wish to use, or need to use, because they are ridiculously overpriced. These industries don't think that way because they want profit, however, if piracy was stopped, then no one will buy their products anyways because they still can't afford it. Popularity of the product will decrease, and the marketing of the product basically just failed. We need to compromise something so that piracy is decreased until there is no more. But suddenly stopping everything in one shot with something like SOPA isn't the way to go. Disagree I disagree. The internet should be free and open. We need to educate people not to download pirated software, movies and music. Doing so is the same as stealing from a shop, which most people would not do. Most people would be prepared to pay small amount for the right to download these things. If governments try to remove websites, it is the same as censorship which sometimes happens in dictatorships but should not happen in free societies. We really need freedom for the internet, so that we can easily share our own ideas, and thoughts. Unlike China, where people can't even talk gossip about governments, which is a basic human right. But China is still very famous for internet piracy. The United States should not have the power to prevent freedom of internet because they are not the world's police force. They should not have the power to dictate what happens in the rest of the world. That's why internet freedom should not be sacrificed.

Explain: As microprocessors become more powerful, mobile phones are changing into hand-held computers. As a result, most of their value is now in software and data services. This is where America, in particular Silicon Valley, is hard to beat. Companies like Apple and Google know how to build overarching technology platforms. And the Valley boasts an unparalleled ecosystem of entrepreneurs, venture capitalists and software developers who regularly spawn innovative services. march 29 cream

It is all about microprocessor and how powerful it is. According to this article, it concerns with Nokia mobile phones as the company develop so much on hardware, which lack in software nowadays. In the other hand, Apple provides a really good with software, because they are mostly useful and impressive. So, now it is quite hard for Nokia to fight against this advance of Apple.

manned aircraft couldn't provide. Also, UAS could be used to fly in to observe or take samples after a chemical or biological attack. Any missions too dangerous for manned aircraft will be taken care of by the UAV. UAV have other advantages over manned aircraft as they have more detailed information about their targets, their strikes are more accurate and cause fewer civilian casualties. They are also cheaper and smaller. Since they have no pilot, the space could be used for fuel and thus they can fly much longer than manned aircraft. Without the need to accommodate crew, drone can be given radar-cheating stealthy shapes and can maneuver better. There are however a problem afflicting the drones as they depend on two-way satellite communications. If the datalink is broken the remote pilot will lose control of the aircraft. For missions requiring constant oversight, the vulnerability to electronic jamming or a direct attack on a communications satellite is a huge problem. Another problem is that the dones has a slight delay between the remote pilot and the aircraft. To reduce latency, small, solar, or laser powered ultra long endurance drones can form a chain in the sky along which satellite signals can be bounced. To reduce the workload on pilots, big UAV can take off and land automatically. The US Air Force plans to have a pilot operating up to four drones at a time. Civil liberty advocacy groups have raised concerns about targeted killings by drones. Bus as long as a UAS pilot can trust data from remote sensors, he or she should be able to make a proper assessment the same ways as the pilot of a manned aircraft. UAS pilot will be in a better position to do so since he or she will have more time to assess the situation accurately and not be exhausted b the physical battering of flying a jet.

Allowing the UAV to fire a weapon based entirely on its own data analysis raises a lot of ethical problems. Using UAV to kill enemies thousands of miles away is like a cowardly action of a bully sheltering behind superior technology. There are fears that UAS will lower the political threshold for fighting and an essential of restraint will be removed. Drones make leaders fonder of war.

Most smart appliances have an accompanying application. Those applications are available on iOS and android. (Samsung's washer and dryer application is working on only iOS and Samsung's Galaxy mobile devices, not the rest of the Android devices.) There are some examples of using iOS to control the smart appliances 1. LG Smart ThinQ LFX31995ST LG Smart ThinQ app will tell you the internal temperatures of both the refrigerator and freezer, and whether it's on energy-saving mode or not. You can make grocery lists and automatically update your inventory once you've checked an item off the list. Also, you can search for recipes on the fridge based on what your fridge has in stock. 2. Whirlpool WRL767SIAM Side-by-Side Refrigerator with 6th Sense Live it transmits information directly to the free app on your smart device. Whirlpool's app can let you know, if the refrigerator door is open or if there has been a power outage. Whirlpool has also enabled this refrigerator to connect to the smart grid if it's available in your area, which will let you monitor energy usage through its app. 3. GE Profile PT9550SFSS Built-In Double Convection Wall Oven The game-change app turns your phone into a remote control for the oven. You can set the temperature, mode, and time for both ovens independently and turn them on with app. 4. LG Smart ThinQ LRE3027ST oven Smart ThinQ app will allow you to search for recipes and then cue up the cook time and temperature accordingly, but you still have to manually press start on the oven itself.

To what extent do you think social media opens the door to freedom? march 1

If passed, it would "accelerate" the net down a path that could lead to governments everywhere sanitising online content so citizens only get what those in power think they should see... What does this mean? may 19 nat

This means that once the bill passes, the government will have control, and block any sites that they think people should not see, and this quote is saying that the people will only be able to see what the government approves of, leaving them with no freedom on the internet.

Describe the steps for removing malware. All September 2 Champ

- First, you must know that your computer is really having malware. If your computer slow down, maybe it just doesn't have enough RAM. You can check by using system cleaning tool called CCleaner, it is a best known for cleaning out files, cookies, and also can clean your hard drive. After using CCleaner, you should restart your computer. - run the Anti-Virus scan and try to restore your system. By doing so, you will need system backup, to save your important documents. If you did not back up, you can use Malwarebyte's Anti- Malware and try deep scan. If the scan still doen't work, you might have to spend sometime uninstalling things that you doesn't want but it is not so affective because most of them are not able to uninstall. It is more effective to use free virus scan. - Use Virus Scanning Tools 1. Kaspersky- it will tell you the infection. It takes about two hour depending on your software. 2. Norton Power Eraser- It will scan and clean your computer for free. 3.Trend Micro HijackThis- It can generate log and you can post these log in forum such as Bleepingcomputer.com or Geekstogo.com where experts can view your post and they might give you some advices you.
