When Your Home PC Needs a Repair?
Computers are becoming as commonplace in homes as television sets. Many people use their home PC for many reasons. If your PC begins to lose performance or stops working altogether, then you may need to take it to a pc repair shop.
Make sure you backup all of your personal files before taking your computer into a pc repair shop. This is assuming that your PC is still working. By making a backup, you already have your important files. If the technician backsups your harddrive, then it is likely to cost you more money. Save his time and your money by doing your own backup.
Find the most reasonable pc repair shop by getting quotes. You will know the prices of the pc repair shop you select are fair. Doing a little homework about the costs of fixing your computer can ensure a good deal. If you know someone who has had their computer repaired, then ask them for a referral.
Ask the technician to diagnose your problem but not to replace any parts without your approval. You do not want a surprise on the bill. The pc tech should be able to give you an estimate of the cost to replace the component. You may opt to not have the part replaced. If the cost is too steep, then a new computer might be your best bet. If you are not afraid to open up your computer case, then you might want to replace the part.
Home pc repair can save you money and can be relatively simple. It all depends on what hardware needs to be replaced. Power supplies and memory sticks are the easiest components to replace. Physically replacing a harddrive is not that difficult but loading all of you software will take some time. Replacing the motherboard and CPU can be expensive and difficult.
If your pc needs to be repaired, then check into all of your options. If your computer is still under warranty, then get in contact with the manufacturer. Should you decide to take a technician, do some homework to find the best quote. Fixing your own pc might be a daunting task but with the right support can be the least inexpensive way to get your computer running properly.
Not in the sense that humans do. However computers can be programmed to develop their abilities and broaden their range of tasks. On the internet there are examples, like intelligent routers. Over a period of time they will build a database of other computers and routers that communicate with them. They can then become more efficient at sending data across the internet, by sending it to a router that it will know can pass it on a shorter or quicker route. This is just one of many examples of how computers can learn. But they have to be designed to do so, so the ultimate control still remains with those that design the hardware and software.

What is a negative way of using a computer?
Negative ways to use the computer include anything that is illegal, fraudulent, hateful, harasses others, goes out of the way to annoy others, or invades the rights or privacy of others. Here are some of the examples:
Cyberbullying - This involves directing towards any person, any persistent or organized online pattern of harassment, name-calling, threats, admonitions to commit suicide, organizing to physically attack another, organizing to destroy property, defamation (ie., libel and slander), invasion of privacy, and/or hacking. It is still considered cyberbullying if such things are done via a phone rather than a computer. Hacking in the context of cyberbullying would be done to steal photos to be used against the person, snoop through their email or text messages to look for gossip, plant incriminating evidence on someone (such as illegal pornography or terrorist threats), or just to vandalize. Cyberbullies might steal sexting photos or embarrassing photos and distribute them. Or they may steal innocent photos and use Photoshop to turn them into something horrible, then distribute them. Even unlawful surveillance can be considered cyberbullying, such as the college students who filmed a gay student having sex and who drove the student to commit suicide.
Fraud, identity theft and Phishing - Fraud is any activity that involves trying to cheat another person or steal their property or money. For instance, someone sends you an email saying that you won millions of dollars, but that you have to send them money as a claim fee to get it. It should be obvious that if you really won, they can deduct any fees from the winnings. If they really have money to give you, they won't need to ask you for any.
Identity theft is related to fraud in that while they want to steal your identity, the purpose of doing so is to steal money or commit other crimes. For instance, someone may say in an email that they are giving you money. They will say that they lost rich relatives, that you are the only one they can trust, that the government cheated them out of what is theirs but that they have a lawyer who can help them if you also help them, and that they will give you a cut of their lost money when they reclaim it. However, they will request that you give them copies of all of your official documents, usually to steal your identity and run up debts in your name, but this same setup can be used to commit fraud/theft. Instead of asking for your documents, they just want your name, email address, home address, and phone number. In that variation, it is fraud, since they will mail you a bad check to cash and tell you to send most of the money back to them. Since the check is bad, they just tricked you into robbing your own bank. The bank will soon be aware that the money is bad and guess who will have to pay it all back? Not the thieves who were behind it all.
Phishing is related to identity theft and fraud as it is a technique for doing either. What they do is pretend to be someone you likely trust. Some do this to get your passwords. They will pretend to be your bank or an online store (eg., Amazon) or auction house (eg., eBay). If you have an account with them and don't read the email carefully, you may click a link to a fake site that looks like your trusted site, where you give them your login details to the real site. Or they may pretend to be a trusted site, and rather than get your password, they are simply demanding payment. The IRS director once received an email claiming to be from the IRS, saying he owed them several hundred dollars. While he admitted he was impressed by the graphics of the fake site, he said he knew right away that it was fake, since the IRS never does business by email. They do business by mail mainly, though in some cases, you may have to meet with them in person.
General crimes - Criminals may use computers for the purpose of running gangs, selling drugs, selling fake documents, selling weapons, distributing illegal pornography, running scams, illegal gambling, prostitution, committing fraud, threatening others, putting out hit contracts, or trying to locate people they intend to assault or murder. So the Internet and phone technology can be used to commit the same types of crimes that are done offline, or to facilitate offline crimes.
Illegal hacking - This is done with the purpose of vandalizing, stealing data or information, snooping, harassing others, spreading malware, interfering with Web traffic, spying on people, or even stealing money. This differs from ethical hacking where companies hire hackers to attack their system so they can find out what needs fixed to prevent that.
