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 this science.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. This new science 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 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. 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.It 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 and the study of this subject is constantly growing along with technology.
Gone are the days of the messy and chalky blackboard, both in the classroom and in conference centers. The blackboard has been replaced by the whiteboard. Users write with dry-wipe pens instead of chalk. The pens come in about eight colors.Dry wipe pens leave marks that can simply be erased using a duster or clean board duster. The pens do leave a powdery residue when the board is wiped clean. Using dry wipe pens is considerably more expensive than chalk, but much less messy.Whiteboards also make excellent additions to home offices, kitchens and garages. Jot your notes, to do tasks and phone messages on the whiteboard and they will never be lost, as pieces of paper will be.A whiteboard will allow you to prioritise all the tasks associated with running a business from home. Planning is made much easier, too. My Internet business revolves around my white-boards.Whiteboards come in a wide range of sizes, though the common sizes are 3 feet by 4 feet and 6 feet by 4 feet. Buy the biggest one you can fit on your wall space, because you will manage to fill it much faster than you think. You may have to buy from a specialist office supplier, like Viking Direct, because high street stores are often limited in the stock they carry.Interactive whiteboards are another ball game entirely. An interactive board will cost hundreds of dollars, as opposed to a dry wipe plastic board that only has a cost of thirty dollars or so.An interactive board allows users to use special non-marking pens that appear to write on the surface, but the board clears when the computer attached to the whiteboard is switched off.The interactive board comes into its own when it is used with specially designed software that allows users to project spreadsheets onto the board, then draw on the board with special "pens", that leave a colored mark on the board, which disappears when the PC is turned off. There is really no mark there at all.
If you own a computer and in todays world who doesnt sooner or later, you will want to have access to the Internet.The Internet for some is the Holy Grail of the modern age, and not having access to it is seen in some quarters as sacrilege.But how do you connect to this Holy Grail the Internet?You need an Internet Service Provider or ISP who will give you access and you need to decide between dial-up service which uses a regular telephone line, and broadband service which, very often comes in the form of Cable, Digital Subscriber Line (DSL), Satellite or T1 connections.Do not get thrown off by all the computer talk. The option really is yours to decide on the type of service you need especially if you are working within a budget.You must first determine what you will be using the Internet to do. If you will be checking email and accessing the Internet occasionally, then, you may need to consider dial-up service. Dial-up service is cheap with a couple of disadvantages. It uses a telephone line to dial-in to the ISPs network and when the connection is made, you are not able to take or make calls.With dial-up service, you need to make sure that the ISP offers local numbers where you are located because you do not want to incur any long distance charges which can be expensive and unnecessary.Additionally for dial-up, you will need to ensure that you have the right hardware to interface with the ISPs network. You will need a modem for this service and these are not very expensive today.If you have determined that dial-up service is not for you, then your choice is going to be one of the following: Cable, Satellite, DSL or T1.Cable can be a good option because of its speed and the fact that you can receive a bundle of services at discounted rates depending on the provider you choose.Some cable providers will have special pricing packages on Internet service if you sign-up for regular cable TV service as well. They will even give you, free of charge, antivirus software to protect you computer from being infected by viruses.For a cable connection to work, you will need a network card and a cable modem. If you have a modern computer, a network card may already be installed as these are now being included as standard components in computer systems in recent years. You can buy a cable modem or your ISP may include one with the plan you choose.Another option, DSL uses a telephone line for Internet access. Your local telephone company may offer this service or you may be able to obtain service from an independent provider who does not offer regular telephone service. Just check with providers in your area to see what is available.DSL, like cable, is faster than dial-up, and like cable, actual connection speeds will vary depending on your location and how many persons are actually connected at the same time. You may want to verify how many persons in your area are being serviced by the same ISP to assist you in your decision making as to which provider to choose.Satellite and T1 connections can be expensive but may be the option available to you depending on where you are located.If you have to use a satellite connection, bear in mind that you will need satellite equipment for the system to work and you must have an unobstructed view of the southern sky.One very important point to consider if you will be using a broadband connection is that your computer will always be connected to the Internet unless you turn your system off. You will therefore need to protect your system by installing a firewall and antivirus software.Ultimately, the final decision is yours. The good thing is you have choices so do some research before you buy.
