Binary Fun!

Binary is a code made up of 1's and 0's. These values are used either by themselves or in combination to represent negatives (0), positives (1), entire numbers, and even alphabets. Computers use the binary system because it is more natural for them, since computers read information as either the presence or lack of an electrical charge. The 1 would stand for a charge and the 0 would stand for the lack of a charge. 

The binary system is based on the power of two. Binary is divided into columns:

Binary can be translated by using these columns:

To translate the binary number (01101010) into a decimal number (which is what we humans use), you would add

64+32+8+2. The ones represent a number and the zeros do not. So the binary number 01101010 would be the decimal number 106!

This form of binary code is known as 8-bit since it contains 8 numbers. Bit is short for binary digit. An 8 bit binary is also known as a byte. There are other bits including 4, 16, 32, and 64.

It is also quite simple to convert a decimal value into binary. You simply divide your decimal number by 2, and write down the remainder, repeating the process until you can longer divide by 2.

Lets use the random number 321 as an example:

321\2=160 with a remainder of 1

  160\2=80 with a remainder of 0

    80\2=40 with a remainder of 0

    40\2=20 with a remainder of 0

    20\2=10 with a remainder of 0

      10\2=5 with a remainder of 0

        5\2=2 with a remainder of 1

        2\2=1 with a remainder of 0

So, the number 321 is represented in binary form by 10000010.  Binary is actually very simple and fun once you get the hang of it.  It's also a great way to impress folks ;).

CCleaner: Your PC Wants It

CCleaner is an amazing little program (about 2.7 Mbs installed) that helps keep your computer fresh and clean. It is simple to use, and Piriform (the company that makes it) works hard to keep CCleaner up to date.  I have personally been using CCleaner for well over a year. It has helped keep my PC running like new.
CCleaner cleans out your browsers cookies, history, temporary files and more. You are able to customize what you would like cleaned and what you would like left alone by placing checkmarks in boxes next to the cleaning options.

CCleaner also has a registry cleaning feature. You are able to scan for issues and then fix selected issues. You can save a backup of your registry before fixing, as well. CCleaner has many other useful features, such as add/remove programs, and the ability to view and delete old restore points.

Piriform supports CCleaner and its other applications through donations and the inclusions of the Yahoo toolbar in its installers. If you do not need the Yahoo toolbar, be sure to uncheck the option when installing CCleaner.

All in all, I highly recommend CCleaner. It is a versatile, highly customizable, and easy to use program with many helpful features. Plus you can't beat the free price tag!

What is Malware?

Malware is a broad term used to describe any number of different types of infections your computer can get. Malware is any kind of malicious software, including viruses, trojans, spyware, adware, and worms.  While some malware can simply be an annoyance, other forms of malware can severely damage your computer causing programs to crash or even stopping them from running. There are also forms of malware intended to steal personal information or to prevent an internet site from providing its services to customers and members (Distributed Denial of Service attack or DDoS).
Trojans (aka Trojan Horses) are some of the most prevalent forms of malware in my experience. Trojans are so named because they often come disguised as a legitimate program such as a game hack or even an antivirus software!
Spyware is a form of malware that can track and collect a users personal information. Often spyware can be hidden in something legitimate such a music download. Adware is quite a bit like spyware, except that its main purpose is to present various advertisements to a PC user.
A worm is a self-replicating program that can send copies of itself to other computer users over a network. Most worms were designed to simply spread themselves and their payloads(i.e. the worm's "cargo").
A virus is a malicious program that can infect computers when its "host" program is run. It can infect other programs and spread to other computers by being passed on in an infected program. Computer viruses are very much similar to a human virus.
These are broad definitions of a few types of common malware. There are other types of malware in existence, which I will go over at a later date.
Remember, one of the first steps to prevention is with knowledge
