In the not to distance past, antivirus firewall software did not exist. You would have to purchase antivirus software, firewall software and spyware all separately. There was not an all in one package containing all three together in the same suite like there is today. Software manufacturers are now making software in combination packages that are a perfect fit for small business owners and home computer use too.

Antivirus Firewall Software comprises three parts. One is the antivirus portion that keeps viruses from attacking your system and can remove those already on your system. Another part of the system is the Firewall software that prevents any information from your computer or to your computer without your permission in the prescribed code written into the software. The third part of the software would be the Spyware Software to prevent and remove Spyware from your system.

Why do you need all this protection you ask? Antivirus Software is to prevent and remove viruses from your computer. Firewall software is to prevent hackers and hacking software from accessing your personal information like bank account numbers or your identity. Spyware software is to prevent and remove Spyware from your system. Spyware tracks your movement on the Internet for reasons that can be good or bad. The good is depositing cookies on your computer to recognize you when you revisit a site. Banks use this type of cookie to help keep other people from accessing your information for example. Some sites use cookies for advertising purposes. Some of these are harmless and some are not.

How does each of these work you ask? Antivirus Software scans all incoming data from email, Internet downloads and file sharing you may have with other people. Any good Antivirus program updates itself often to keep up with all the new known codes viruses are written with. Without keeping current the software can not know which codes to exclude. New viruses are written constantly in very large numbers. Virus codes can be very complex and creative but are written in code just like beneficial software. Keeping up to date is critical for good protection.

All computers talk to each other using data packets. This is where Firewall Software comes in. It is the job of the Firewall Software to monitor this data for corrupted or altered packets of info. It will not allow any data to enter your system if it notes any packets that are not written into the software to accept. The software can even pop up a box to ask if you want to accept this type of data if it is not recognized. Good Firewall Software is needed to keep your system safe.

The third part of this software suite is Antispyware Software. Spyware programs are not designed to crash your operating system but are designed to spy on all your activity on the Internet as well as files on your computer and gather that data for someone else’s benefit. Antispyware Software is to keep this software from attaching to your computer system and to remove any of this software already on your system. Spyware can cripple your system performance over time if it allowed on your system. I have seen computers with hundreds of spyware cookies on the system and the computer was so slow it was unusable. After the spyware was removed the computer operated at normal speed.

My advice is to purchase good Antivirus Firewall Software and keep it updated. With this type of software loaded on your system you can enjoy your computer for surfing the Internet and for file sharing with your friends or for business purposes.

Same thing with 1GB = 1024MB, 1TB = 1024GB, etc.

Answer:
Because computers work with electricity. Computers function by sending tiny pulses of electricity along their circuts. In each clock cycle, if the processor recieved no flash, then it gets a 0. If it did, it gets a 1. This is how computer use numbers. Computers can deal with 1′s and 0′s very easily. But using only 1 and 0 isn’t very useful on its own. So computers employ a method of counting known as binary. Each digit (or clock cycle result) of binary corresponds to a power of 2, in order from right to left. to write the number 1 in binary is 1. 2 = 10. 3=11, 4=100, 5=101, 6=110, 7=111, 8=1000 and so on. So the nth digit from the right of a binary number is 2^n-1. The totals of each digit are then added to produce the final value of the number. So, 19 = 10011. Usually, binary numbers are also broken up into sets of four digits, to make it easier to read (like commas in decimal, i.e. 1,234,765), with incomplete groups filled up with 0′s. So usually, 19 would look like 0001 0011. If you write the number 1000 out in binary, you get 0011 1110 1000, which is fairly awkward. Plus, each digit couts as a bit, with 8 bits in one byte. Because of this, each level is rounded te the next nearest power of 2. So 1000=0011 1110 1000 becomes the easier (and technically correct) 1024=0100 0000 0000, which is 2^11.
