Solving Crime with Computer Forensics


Computer Forensics is the scientific study of computers or computer related data in relation to an investigation by a law enforcement agency for use in a court of law. While this technology may be as old as computers themselves, the advances in technology are constantly revising the science of computer forensics.

In the technological old days, computer forensics was mostly related to data dumps, printing out every keystroke that had been logged on a computer in a series of eight digits, all of them zeroes and ones. Literally cases of paper would be used for the printing of the materials. Systems analysts would then have to convert all of the data into hex and then translate the value into whatever the actual keystroke was. In this way, it was possible to go over all of the data and figure out at what point the computer and the corresponding program crashed. Like computers and technology, Computer forensics has evolved by leaps and bounds since those days of old.

While all computer language still ultimately boils down to ones and zeroes or binary and then hex, the means by which programs are created, run and utilized has changed drastically. Computer forensics has done well to keep up with the task at hand. Now hard drives can be wiped clean. However, without an unconditional format (and in rare cases, even with the unconditional switch) the data can still be retrieved. It takes an expert in computer forensics however. It takes someone who is familiar with the technology of the computer and the science of computer forensics to reconstruct all of the data that has been wiped off of the hard drive.

Computer forensics can be used to track emails, instant messaging and just about any other form of computer related communications. This can be necessary, especially in the world today. Computer forensics experts have even advanced the technology to the point that they can track data real time, or while it is actually being sent and received. This is a mind-numbing task when you think about the billions of communications going on around the globe at any given time, but the science of computer forensics is constantly advancing every bit as quickly or sometimes even faster than the technology they are responsible for investigating.

Computer forensics is an interesting aspect of technology that is often overlooked. Computer forensics have been used to solve many crimes and should be considered a viable tool in many ways. The study of computer forensics is constantly growing along with technology.

History Of The Computerflip-Flops - A Basic Counter


Flip-Flops - A basic counter



We looked at the Binary system, and basic computer logic elements, in previous articles, "It's a binary world - how computers count" and "How computers add - a logical approach".



Now we can combine two parts of these articles to look at a counter. Another common logic element in a computer is a counter or timer. This can b to count items going past a sensor on an assembly line, or possibly a count-down timer. For example, if you have a late model washing machine it will have a simple computer using a count down timer to give 10 minute wash cycle, etc.



There are several types of counter, nearly all of which use a basic element of electronics, the Flip-Flop. And you thought they were rubber shoes English people wear to the shower or the beach. (At this point Australians say "I thought they were called thongs").



OK back on topic. The flip-flop is as old as electronics, and is a classic example of the binary system. It has two possible stable states, A or B, and can be 'toggled' from one state to the other, just like a 'push-on, push-off' switch. It was originally made with two vacuum tubes (or one, for example a double triode).



It normally has two outputs, one being the complement of the other. That is,if one output(A) is a logic 0, the other(B) is a logic 1, and vice-versa. The input, or Toggle(T) is at logic 0 until a pulse from a sensor, for example, comes along. This pulse takes the logic state to 1, then back to 0. The toggle effect, causing the Flip-Flop to flip, is actually the CHANGE from 0 to 1.



In logic terms the flip-flop is made up using AND and OR gates, in logic cicuitry it is just a 'black box' labelled FF. Several FFs may be grouped into yet another black box, a counter, timer, or multivibrator.



We can make up a Truth Table, which we have used before. If you recall, a truth table tells you what the Output will be for all possible Inputs.



TRUTH TABLE for Flip Flop - Toggle (C)hange,- Outputs A and B.



INITIAL STATE

T B A

0 1 0 'A' output is 0



PULSE #1

T B A

C 0 1 'A' output is 1



PULSE #2

T B A

C 1 0 'A' output is 0



Now we string some flip-flops together to make a counter. Say we have a sensor on a beer bottling machine, which has to count 5 bottles before switching the feed, we need to count up to 5, or 101 in Binary. We will need 3 flip-flops, for binary bits 0,1 and 2, corresponding to decimal bit value of 1,2 and 4.



We will take the A output of the 3 flip-flops to a decoder black box, which we can use to detect when we get to 5, then switch the feed. The B output of flip-flop 0 is passed to the toggle input of flip-flop 1 via an AND gate, so the next pulse from the sensor (which goes to all 3 flip-flops) at this AND gate will toggle the flip-flop, depending on the value of the B output, 0 or 1. Similarly the B output of flip-flop 1 goes to the toggle of flip-flop 3 via an AND gate.



Our 3 Flip-Flops now come up with a truth table like this:-



INITIAL STATE

FF2 FF1 FF0

TBA TBA TBA

010 010 010 'A' outputs 000 - 0



PULSE #1

FF2 FF1 FF0

TBA TBA TBA

C10 C10 C01 'A' outputs 001 - 1



[The (C)hange flips FF0 (always). FF1 & FF2 are blocked by the AND gate which needs a 0 input from the previous FF 'B' output AND the pulse change.]



PULSE #2

FF2 FF1 FF0

TBA TBA TBA

C10 C01 C10 'A' outputs 010 - 2



[The (C)hange flips FF0 (always). FF1 flips beacause the 'B' output from FF0 is a 0 when the Pulse arrives. FF2 is blocked as before.]



PULSE #3

FF2 FF1 FF0

TBA TBA TBA

C10 C01 C01 'A' outputs 011 - 3



[FF0 flips, FF1 is blocked again,as is FF2.]



PULSE #4

FF2 FF1 FF0

TBA TBA TBA

C01 C10 C10 'A' outputs 100 - 4



(FF0 flips, FF1 flips, FF2 flips.)



PULSE #5

FF2 FF1 FF0

TBA TBA TBA

C01 C10 C01 'A' outputs 101 - 5 count complete!



[FF0 flips, FF1 and FF2 are blocked.]



This counter can count up to 111, 7 decimal, it then resets to 0. A couple of interesting points to note are:-



1. FF0 flips every pulse. FF1 flips every 2 pulses. FF2 flips every 4 pulses etc. These facts can be used to make up a divider, which can be cascaded. For example the 4 pulse output can go to a second counter which also gives a 4 pulse output, totalling 16. This can be expanded to make up a decadic counter by decoding a count of 1010 (10 decimal) and using this to toggle the next counter, etc. What about 60 and 12 for your digital watch?



2. Look at the 'B' outputs from the counter. In sequence the values are:- 111, 110, 101, 100, 011, 010 (7,6,5,4,3,2 decimal). See the pattern? That's right - a countdown timer! We'll be using this in a later article.

Computer Repair Basics for Beginners


Is it possible for regular Joe's to fix their own computer without needing to call a specialist in to do the computer repair? Yes! You can do it easy, and you can learn these computer repair techniques easy in the article I have written. You will be told exactly what you need to do and know, in order to get your computer repaired and working how you want it!

There is always the option of calling upon a company like Geek Squad, from Best Buy, if you have the extra $350 to repair your computer. Let's also state here their idea of computer repair is not what you need at all, unless you are looking for someone to come to your home with the intention of selling you software you don't need, instead of repairing your computer. Later I will indulge all of you reading, my experience with this company, and how it brought amusement into my world

Going through only the computer repairing techniques we need to know, I will not waste your time with confusing nonsense about how a computer works, or how did the computer get broken in the first place where it is in need of computer repair? Who cares right? What's done is done, lets just fix the darn thing.

I will show you how to do computer repair the easiest, most simplest way possible. We care about making our current computer situation better as it exists at this exact moment, ridding it of needing computer repair.

The computer repair basics presented here and the articles that follow will be more than enough to eradicate 90% of your home computer repair problems, completely resolving them all so you don't have to search the internet anymore for "computer repair" and how to fix your computer problems.

You could be thinking, as I at one time did when I knew very little about computers or repairing them, that it will be near impossible to understand these square mysterious beeping towers or how they work none the less. It is a lot easier then you might think! You just need to know the what information is important about computer repair, discarding all the unnecessary stuff that most computer repair companies say in order to confuse you so you hire them. We do not need them! We have ourselves and by gosh darn it, we have this helpful article to guide you thought basic computer repair.

Computer repair steps are all the same.

Let's repeat, computer repairing steps are all the same, no matter if it is you doing it or a computer engineer doing it. The computer engineer goes though the basic steps while repairing a computer system, the same steps we are going to go over in this article. He might know what to do in that chance of 10% when a computer is more damaged then normal, but we are not going to worry ourselves with that odd chance.

There are not hundreds of computer gurus that develop new and innovative ways to repair computers. Computer repair techniques have already been mapped out for us, and proven, so lets just utilize other peoples work and findings about computer repair, after all its free and legal!. Think of the same situation where you look up a recipe online to cook a fancy meal, it is the same idea!

Now, I have been prepping you for too long telling you why I think you can do it. You know you can do it, you just need to believe in yourself and take computer repair one step at a time. I cannot stress that enough. Computer repair has to be done in steps...1) before 2). Yes it sounds obvious but be strict on yourself about his, especially while learning how to do computer repair, you will make it easy on yourself.

Usually when we fix something in life we have identify the problem.. blah blah. Skip identifying the problem! (not how you learned it in school huh?) Lets not even try to pinpoint a problem that needs repairing with our computer yet!

We are going to first do a few very easy computer repair basics that will solve almost all computer issues (shhh overpriced Geek Squad doesn't want you or anyone to know this).

First Guide in Computer Repair

1) Click the Start Menu, a button that is visible while hovering over the start menu is the "run" button. Click the run button and a small window in the bottom left of your screen comes up.

2) Type "msconfig" (with no quotation marks) in the box that is within the window.

3) Another window comes up, now go to the tab to the right called "start up"

4) Near the bottom of the window is a button called "disable all" click that button

5) Then click the "apply" button just below the "disable all" button.

6) X out of the window (close the window) and another window pops up. Click the "restart now" option.

And there you have it! You just taught yourself how to do a very easy computer repair technique which will solve alot of your computer repair issues.

I'm a regular guy who has recently taken interest in the computer repair field, and learned some things that can help others with their everyday interaction with computers. I remember about two years ago I knew nothing about computers, that gives me the mind set to explain in layman's terms how to help the masses who think they don't know enough to fix their home computer issues.



90% Of Personal Computers Are Infected With Spyware Or Adware Programs, Is Your Computer One?


Latest estimates suggest that up to 90% of personal computers are infected with some form of spyware or adware program. It's important to stay alert and watch for signs of infection on your computer, because some of these programs can do some serious damage to your computer. Let's take a look at some of the main malicious software (malware) warning signs to watch for.

When you open up your browser, has your home page changed? If you go back in and change the settings back to your original choice, you may find that next time you open the browser it's changed again, usually to a different page from the last time. This is probably one of the most common indicators that you have spyware on your computer, so if this happens, get your system cleaned immediately.

Pop-ups are an annoying part of life on the Internet, but if you start getting pop-ups appearing that have your own name on them, be wary. If the pop-ups appear even when you're not connected to the Internet, or your browser is closed, then you definitely need to get your system checked.

Spyware often installs a new toolbar onto your computer system. So if a different browser or search toolbar suddenly appears, and you can't seem to get rid of it, you're most likely dealing with some form of malware at work. Even if you manage to get rid of it, chances are it will keep coming back unless you know exactly how to remove all of its files.

Perhaps you've just discovered that your Favorites list has been 'tampered' with. It may be that some new items have appeared that you don't recognize, or perhaps others have disappeared. If you delete them and they come back again, it's probably a spyware infection.

An infection of malware can often make your computer run really slowly. If you find that your system seems to run constantly at 100%, even when you have very processes operating on your computer, then it's likely your computer has been infected by spyware. Computer programs require a certain amount of free space to operate properly, so when spyware is chewing up all your resources, your computer may run at a frustratingly slow speed.

If you find you enter something into an Internet search bar, and instead of going where you expect you end up at an entirely different search engine, then it's likely malware has taken a hand.

Check your modem if you can, and see what the lights are doing when you're not actually using the Internet. If there are lights blinking, or something on your screen suggests that data transfers are occurring, be suspicious. Malware is probably sending or receiving information without your knowledge.

Unfortunately, there are also varieties of adware and spyware that don't alert you to their presence at all. So you need to check your system as a matter of routine, even if you don't observe any warnings signs of infection beforehand.

Don't let your computer become infected with spyware by visiting PC-Security-Guide.info where you will find helpful information and resources on email security, spam scams, spyware, adware and pc virus recovery tips that will keep your personal computer running virus free.
