Computers

No offense, but DUH!! Wouldn't you need alot of knowledge for fixing a computer, unless your have some kind of miracle gift or what not. I think there is alot of education required for this type of career.

No offense but there is almost no level of education required to be a computer technician. In fact, I have a friend that went to school at Oxford. She has a Doctorate in English Grammar and Composition. She was an editor of computer manuals for both IBM and MICROSOFT. She said the the manuals were notoriously boorish not written well, and grammatically incorrect. She once told me that most of the computer "greats," have no formal education at all. Some of them attended private schools in England and Wales. Some of them went on to college, but not all. There is no national accreditation in the USA or in Europe. As a techie no one knows what you are doing and you can claim anything. My Doctor (LIT) friend moved to the USA and it was no different. Many techies claim college, but when you begin asking them if they took Calculus or Differential Equations, they start getting all Smokey and begin stuttering and stammering. Of course some of the ones that have college degrees in Computer Engineering of went to college. Then the question is how many times were they

allowed to take each of their courses like linear algebra, circuit engineering , and systems analysis, and so forth? Did they attend prep school or private school where they were spoon fed the answers? Did they have tutors and what college did they go to Georgia Tech, MIT or Princeton?

We are living in a digital world, were computers are not just an ordinary thing anymore but a "necessity" to our everyday lives. Most of us only knew a little about computer security threats, the most common were "virus" and "worm".

But did you know that there are 34 different types of Computer Security Threats?

Spam

Spam, or unsolicited commercial e-mail, may seem like the least of Internet security threats, but it really robs people of their time in having to constantly clean out the junk in their in-boxes. The other serious problem with spam is that it brings in viruses through attachments and tricks people into going to malicious websites. Spam can be a gateway to more severe threats.

Viruses

Viruses can come from email, websites, discs and other computers. Viruses come in many types and strengths. A virus can be a program that simply causes your computer to slow down, or it can totally wreak havoc on your computer system, forcing you to reformat your computer. The best way to avoid viruses is to avoid downloading software that you are unsure about. Viruses can work to immediately disable or control your computer, or they may wait for a certain date to activate. Most antivirus software can prevent viruses quite easily.

Adware/Malware

Malware means malicious software. It is code that installs itself on your computer without your ever knowing how you got it or where it came from. Malware may simply slow your computer down by reporting to other websites what you are doing, such as which websites you are visiting, or it can cause unending pop-up ads. Malware can be used to steal personal information, or it can completely take over your computer. Many programs are aimed at stopping and removing malware, similar to the way antivirus software works.

DOS Attacks

Denial-of-service attacks are among the most serious Internet threats. Remote computers will take control of many computers on the Internet through viruses or malware and direct all of those computers' resources toward using all the resources of a website or database or an organization's infrastructure. The draw all at once on a system makes it come to a stop.

Information Theft

The silent security threat of the Internet is information theft. Many people already know that identity theft is a serious problem, but identity theft is done easily online. Criminals hack in to large databases of consumer information to steal your identity, but individual information can also be stolen from your computer when you get infected with a virus or malware. Your bank account number and passwords can be stolen from you as they are transmitted online.

Boot Sector Viruses

Boot sector viruses spread by modifying the program that enables your

computer to start up.

When you switch on a computer, the hardware looks for the boot sector program -

which is usually on the hard disk, but can be on a floppy disk or CD - and runs it. This

program then loads the rest of the operating system into memory.

A boot sector virus replaces the original boot sector with its own, modified version (and

usually hides the original somewhere else on the hard disk). When you next start up,

the infected boot sector is used and the virus becomes active.

You can only become infected if you boot up your computer from an infected disk, e.g.

a floppy disk that has an infected boot sector.

Boot sector viruses were the first type of virus to appear, and they are mostly quite old.

They are rarely encountered today.

Bluesnarfing

Bluesnarfing is the theft of data from a Bluetooth phone.

Like Bluejacking, Bluesnarfing depends on the ability of Bluetooth-enabled devices to

detect and contact others nearby.

In theory, a Bluetooth user running the right software on their laptop can discover a

nearby phone, connect to it without your confirmation, and download your phonebook,

pictures of contacts and calendar.

Your mobile phone's serial number can also be downloaded and used to clone the

phone.You should turn off Bluetooth or set it to "undiscoverable". The undiscoverable setting

allows you to continue using Bluetooth products like headsets, but means that your

phone is not visible to others.

backdoor Trojan

A backdoor Trojan allows someone to take control of another user's

computer via the internet without their permission.

A backdoor Trojan may pose as legitimate software, just as other Trojan horse programs

do, so that users run it. Alternatively - as is now increasingly common - users may

allow Trojans onto their computer by following a link in spam mail.

Once the Trojan is run, it adds itself to the computer's startup routine. It can then

monitor the computer until the user is connected to the internet. When the computer

goes online, the person who sent the Trojan can perform many actions - for example,

run programs on the infected computer, access personal files, modify and upload files,

track the user's keystrokes, or send out spam mail.

I'm not exactly sure what you are asking, but here are some possible answers:

• If you are wondering how to put pictures on your computer from your camera, get a cord that connects the camera to the computer, and if you have a mac, wait for the pictures to pop up, or if you have a PC, wait for a window to pop up asking you what you want to do, and select which program you want to open your pictures with or where you want to save them. You can do it digitally like that, or you can just take the SD card out of the camera and put it into the SD card slot on the computer.
• If you want to know how to find images on the Internet search for something on google images, right click on the picture, and save it where you want to save it on your computer (usually My Pictures)
• If you want to find pictures you already saved, either open up Microsoft Picture Manager for a PC, or iPhoto for a Mac and then choose which pictures you want to open. You can also find and open a picture by opening the folder you saved it in (My Pictures, or Karen's Folder are some examples). Then double click on the image to open it.
