What is a Computer Virus?

Computer viruses can be small or large applications that contaminate files inside your computer and are capable of transferring from one computer to another. They can do one of many things that include gaining access to information or to corrupt information within a computer system. Some computer viruses can actually be fairly harmless which may include Pop Ups but can also be crippling to a computer and can even wipe, copy and steal your files and personal data. Like other software programs, someone must create and write a computer virus and once they are created, viruses can duplicate themselves to anything that is attached to the infected computer.

What is Spyware?

Spyware, adware, and malware can be software put onto your computer usually without your consent. Spyware gathers internet user information without their knowledge for advertising purposes.

Processor / CPU

A Processor otherwise known as a Central Processing Unit or CPU is the heart of your PC or computer. Most devices including tablets like the Apple's iPad or mobile phones like the iPhone have a processor of some sort in the device. In regards to a computer or Laptop the processor can be a cheap upgrade for any user who wants to get that little more power out of their PC.

Harddrive

The Hardrive is what we call the brain of the PC or Laptop. This is where all Data is stored which includes pictures, videos, documents and even the operating system itself for example Microsoft Windows. The amount of data that can be stored on a harddrive depends on the size of the device which can vary quite dramatically. This is usally the most important part of a PC because for most people all their personal data is stored on this fragile device.

Computer Memory / RAM

Computer Memory otherwise known as RAM (Random Access Memory) is a static storage component that stores data on a temporary basis. People often confuse memory with Hard Drive memory which are actually completely different components. These can be an effective way of upgrading your computer's performance by increasing the amount of memory in your computer or laptop..
