The idea is not quite as crazy as it might sound, though you may wish to limber up your mind before delving deeper. It’s based on the same principle as that of quantum entanglement — the notion that two particles on opposite sides of the universe can be linked through their quantum states such that one cannot be adequately described without the other. That is, an action on one particle instantaneously influences its counterpart, even if they are separated by light years.

This quantum non-local phenomenon cannot transmit information faster than the speed of light, but according to Volkmar Putz and Karl Svozil at the Vienna University of Technology there’s no reason we can’t process information at superluminal speeds as long as doing so doesn’t create any time travel paradoxes.

All we need to do is create a medium conducive to the kind of pair formation and recombination described by entanglement. Such a material would have a refractive index of less than one. Then you simply build an optical computer around all of this controlled quantum mayhem, and presto: a computer that processes faster than the speed of light (in theory, anyhow).

We can’t move information faster than the speed of light, but it’s nice to know we could potentially process data at that speed. And supposedly a hypercomputer of this nature could digest and compute functions that are otherwise non-computable. But even so, the bright minds over at Technology Review can’t figure out exactly what to do with such a hypercomputer, and frankly neither can we. But if it can keep more than ten tabs in Firefox open simultaneously without crashing, we’ll take a dozen.

Considerations when buying a computer

Processor – Type, Brand and Speed- Ask what processor is in the machine. The most common processor manufacturer of all time is Intel who came up with the popular Pentium series. Other competitors are AMD and Cyrix to mention the top three. I will not use this as a platform to advertise any particular manufacturer. Get your supplier to explain the various processor types and merits of each one. There is not enough space to exhaust the comparison. In the Central Processing Unit,(processor), that is where processing takes place. The processor works on millions and billions of instruction cycles person commonly referred as Megahertz (MHz) or Gigahertz (GHz). The more the faster. On desktops it can be possible to change the processor without having to change a whole unit. See upgrades below. This is one important aspect to look at in comparing one machine to the next. You are able to check the processor speed on the computer’s properties. Ask to be shown the speed of the processor. I have seen people duped to believe the machine is 2.4GHz only to realize it was actually 1.4GHz.

Permanent Storage space – Hard disk drive capacity. All storage is in bytes. Commonly referred to as Megabytes (MB), Gigabytes (GB) or Terabytes (TB) meaning millions, billions and trillions of bytes. Depending on user’s needs a 40GB Hard drive may be adequate for home use but not proper for a graphic designer with advertising agency. Consider this, a 40GB Hard drive can only contain 9 DVD movies.

Temporary Storage – Commonly referred to as memory. It is also technically called RAM (Random Access Memory). This is where programs and data are stored temporarily as the computer processes. It is the equivalent of your workbench in the office. When you bring files from permanent storage (cabinet) to the desk to work on them, when you open many files and folders and leave them on desk. This tends to slow the computer just the same way it confuses you when you open several files and folders at the same time. The more RAM you have the faster your machine can be. This however combines with the processor speed and free space on Hard drive as well.

Optical Storage Drive – Compact Disk (CD) or Digital Video (DVD). Some optical drives simply read information off disk or DVD but will not write. Some read DVD and will only write CD (normally called CD/DVD Combo). In general choose a DVD Writer which can not only write DVDs but CDs as well. Most software is installed from the optical drive. If this does not work you can connect an external USB DVD drive for the same purpose

Monitor type – A monitor is a screen where your information is displayed. LCD (liquid crystal display) is recent technology compared to CRT (cathode ray tube). CRT is obsolete, take more power and occupies more space. The wider the screen the better it is to view graphics, gaming etc. It is measures in inches or cm just like the television set.

Portability / Mobility – This is a consideration in terms of whether you want to be able to access computing facilities away from The office or home. If you need that kind of flexibility then you need to invest in a Laptop or palmtop or The latest mobile phones which have PC functionality instead of buying a desktop which can not be taken around and used anywhere else other than in office or home.

Durability – This is where you check whether The computer is a clone or branded – Clones are not expected to be as durable as branded machines. Clones are literally made of parts from various manufacturers that are put together sometimes in a hurry whereas branded machines are tried and tested in laboratories. They carry warranties and guarantees. They are higher in quality than clones. Clones are for situations where budget for IT is low and you want a quick solution for The season you are in as a business. I recommend clones for home use and Small to Medium Enterprises (SMEs). If you are serious about information security, good value for money then go for branded machines. Common brands are HP, Dell, IBM, Apple, Toshiba etc. Still on durability, consider the age of the computer as you buy. A 2001 desktop will not give you much mileage, in fact you should ensure tou backup your data as all components on the computer have a life span. A new computer should give you a minimum of 3 to 4 years of excellent output. Branded machines can go beyond that time.

Cost Element – Cheap is sometimes expensive. As a college student, one does not need a high powered 300GB Hard drive machine etc. A simple 40GB Hard drive laptop with 512MB RAM is adequate. This is as of 2010. It is certain that in a few years this will have changed somehow. Cost plays a pivotal role in decision making. Realize that the lower the budget the lower the quality of computer you expect to buy except where the buyer is desperate for cash. Cost should not be the only determining factor on which computer you eventually buy. Rather wait, save more then buy something that will last you three to four years than rush it.

Purpose for purchasing – You ask yourself “Is this PC for Home or business use?” If you are using it in the business, which area? Mission critical situations require robust high capacity computers whereas a home computer needs no sophistication as it is usually for basic computing, printing etc. Businesses get fooled with cheaper new computers not realizing that they are meant for basic home use. In no time they flood the company with computers that will soon be overtaken by the needs of The organization

Possibility of upgrade – Consider this if you are someone that follows newer versions of software. In that case you need a computer whose hardware you can easily upgrade. Laptops are not as easy to upgrade as desktops. Sometimes the compartments where RAM is installed require technical knowledge. Do not attempt to open laptops and desktops without adequate training. It may cost you the entire machine. Give it to the experts who can advise you.

Most computers are OK as long a they still run on the same software that was loaded when they were bought. The problem comes when you want to always look at software upgrades each time a new products comes along without realizing that The newer software packages have increased demand on the hardware you may have in place. Wise buying is what I desire from you from this day forward.

The Multi-Touch surface is able to determine multiple touch points at any location on the surface. Used in a musical application, this makes it very easy to play a chord by touching three or more keys simultaneously in a graphical representation of a keyboard.

By using pinching motions on the Multi-Touch screen, you can increase or decrease the size of a web page displayed on an IPod Touch. By using a sweeping motion up or down along the side of the screen, you can rapidly scroll through web pages.

Larger Multi-Touch screens can be built within a reasonable budget. There are many examples of this from hobbyists on the internet.

A number of companies have invested in and released advanced computers with Multi-Touch capabilities. One example is the 15.6-inch Acer Aspire 5738 PG laptop. At less than $800.00, it seems a good buy, but some glitches in the screen have been reported.

Microsoft has developed a computer in a table top which incorporates a large Multi-Touch screen. Dubbed ‘Microsoft Surface’, it became available for use by AT&T customers in 2008. Though still too expensive for the general public, analysts predict wide spread use of such devices in the next few years.

Called ‘The Magic Touch’, the Dell SX2210T 21.5 inch Multi-Touch Monitor brings this technology home. This is a high definition monitor providing 1920 by 1080 pixels of resolution. It is 16:9 widescreen for use on any Windows 7 based home computer. With Dell behind it and at a price of $469, this is sure to become a very commonly used technology in the next few years.

When these tablets came out, they were even more basic than they are now. One of the contemporary ones was put out into the market around the year 1957. This one just did the basics; recognizing signatures, kind of like those that are seen at the cash registers when a person signs for a credit card transaction. The first ones made did not connect to computers as they do now.

Other names that people have given these tablets are digitizers, pen pads, digitizing tablets, or graphics tablets. In the beginning of the ones for computers, there was one called KoalaPad. The Apple ll was the computer that it was actually designed for.

As one point with making these graphics tablets for computers, companies began to put the different types of them into categories. Some categories are passive tablets, active tablets, optical tablets, acoustic tablets, electromagnetic tablets, and capacitive tablets.

When the text or images are drawn on the basic tablets, the images or data will be seen on the computer monitor, not on the tablets. There are ones with higher technology where a person can view anything that is drawn right on the tablets. These higher technology ones have a mini computer screen on them.

Some of the basic graphics tablets do allow a person to use them in replacement of their computer mouse. One accessory that comes with the tablets is what is called a puck. It works like a computer mouse works, only it has bit more technology for navigating. Whether it is basic technology or a higher level of technology one is looking for, these graphics tablets for computers can be quite useful. They serve many functions for each person and their computer needs.

Instructors

When you are working on your certification means that you will come across questions where you will need to speak with the instructor for further assistance. Before you sign up for any kind of certification program you want to find out when instructors are available and at what times. One way to do this is to read the different profiles of the professors to see if you can interact with them through email or a forum.

Training

One of the most important elements that you should consider when working on your certification is the overall amount of computer forensics training that you receive. This is important because the more hands on training that you receive during your certification program the better prepared that you will be for the different challenges that you will be facing in the real world. To determine this you want to see what private corporations or business the school has partnerships with, this is how you can be able to gain actual real world experience when you are working on your certification.

Clearly obtaining a Computer Forensics certification can be very challenging. However by considering the above factors when selecting a certification program will help you to select one that will work well for you. This means that once you have received your certificate you are more marketable to employers because of the education and real world experience that you received as part of the program.

Computer forensics training provides a framework for conducting computer-based investigations. Who has the legal right to access a computer, network, or digital media for the purpose of recovering data or information for potential use in legal matters (computer forensics) or to enforce policy? Training covers the use of forensic software on a hard drives, thumb drives, cell phones or in Random Access Memory (RAM). Computer forensics education includes a discussion of relevant laws. Training is usually provided on the use of software for maintaining log files, pin traps, video surveillance, cracking passwords, and sniffers or key loggers.

Increasingly, computer forensic investigative techniques are employed by law enforcement, businesses, information technology professionals, and individuals to support criminal case development, employee termination or discipline for policy violations, and family law cases. Demand for computer forensic specialists is high. Since computer forensics is a relatively new field, legal and ethical issues may not be well-defined. This is an especially tricky area for the information technology professional who may be required to perform these investigations without the benefit of having specialized training in computer forensics.

Many people usually only have an Anti-Virus program on their computer. Most of the Anti-Virus programs will detect and remove spyware, but not all of them do, and not all of these programs for viruses will offer Anti Spyware support options.

Some people used to think that Spyware only affected how a computer ran, but they soon found out that this stuff is a program, or software, that gets into your computer and can follow your every move. It tracks where you go on the Internet. Ultimately, Spyware can end up being a great annoyance. These little programs are not so little. These can enable someone to control your computer and steal information of yours right from your computer.

There are other things that can get onto your computer and affect its security, configurations, browsers, and its speed. There are viruses, Adware, and then there is Spyware. Some of the Anti Spyware programs can detect viruses and Adware, as well as Spyware. It is a good idea to make sure you cover all your tracks with your computer.

Your computer is your own and it can have some very personal information on it. Having a program that has Anti Spyware Support Options is very important. You want to be able to get help whenever you need to and not have to go out and spend lots of money paying computer technicians to do this for you. This help can be available to you right online, from your computer.
