A Short History of the Modern Computer

First programmable computer

The Z1 originally created by Germany's Konrad Zuse in his parents living room in 1936 to 1938 is considered to be the first electrical binary programmable computer

The first digital computer

Short for Atanasoff-Berry Computer, the ABC started being developed by Professor John Vincent Atanasoff and graduate student Cliff Berry in 1937 and continued to be developed until 1942 at the Iowa State College (now Iowa State University). On October 19, 1973, US Federal Judge Earl R. Larson signed his decision that the ENIAC patent by Eckert and Mauchly was invalid and named Atanasoff the inventor of the electronic digital computer.

The ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and began construction in 1943 and was not completed until 1946. It occupied about 1,800 square feet and used about 18,000 vacuum tubes, weighing almost 50 tons. Although the Judge ruled that the ABC computer was the first digital computer many still consider the ENIAC to be the first digital computer.

Because of the Judge ruling and because the case was never appealed like most we consider the ABC to be the first digital computer. However, because the ABC was never fully functional we consider the first functional digital computer to be the ENIAC.

The first stored program computer

The early British computer known as the EDSAC is considered to be the first stored program electronic computer. The computer performed its first calculation on May 6, 1949 and was the computer that ran the first graphical computer game

The first personal computer

In 1975 Ed Roberts coined the term personal computer when he introduced the Altair 8800. Although the first personal computer is considered to be the Kenback-1, which was first introduced for $750 in 1971. The computer relied on a series of switches for inputting data and output data by turning on and off a series of lights.

The Micral is considered the be the first commercial non-assembly computer. The computer used the Intel 8008 processor and sold for $1,750 in 1973.

The first workstation

Although never sold the first workstation is considered to be the Xerox Alto, introduced in 1974. The computer was revolutionary for its time and included a fully functional computer, display, and mouse. The computer operated like many computers today utilizing windows, menus and icons as an interface to its operating system.

The first PC (IBM compatible) computer

In 1953 IBM shipped its first electric computer, the 701. Later IBM introduced its first personal computer called the "IBM PC" in 1981. The computer was code named and still sometimes referred to as the "Acorn" and had a 8088 processor, 16 KB of memory, which was expandable to 256 and utilizing MS-DOS.

The first PC clone

The first PC clone was developed by Compaq, the "Compaq Portable" was release in March 1983 and was 100% compatible with IBM computers and software that ran on IBM computers.

How a Computer Consulting Business Can Help Your Company

While many small companies only call in a local computer consulting business when something computer-related breaks, there's a lot to be gained by forging a proactive, long-term relationship with a local computer consulting business in your area.

Consider Getting Advice from a Computer Consulting Business

If you need to get advice once-in-a-while on how your computers can be better utilized, or you have a specific computer-related problem that needs to be solved, a computer consulting business is generally the way to go.

However, if computer-systems and information technology (IT) are really important to your industry and your company, outsourcing your computer-related service needs to a local computer consulting business is often a much better solution than just piecemeal, ad-hoc usage of a computer consulting business.

Hiring a Computer Consultant

Many computer consulting businesses choose to specialize and end up becoming extremely valuable to their particular area or niche. In many cases, these kinds of computer consulting businesses can know almost as much about your industry and competitive challenges as you do.

So to help your company grow and to make sure it's not being short-sighted with its computer-related needs, consider getting advice from a computer consulting business.

Wear Lots of "Hats" is Fine... But Don't Let These Hats" Blind-Sight You

Sometimes small companies already have an idea of what their computer-related needs are when they enlist the help of an outside computer consulting business.

There are several advantages to bringing in an outside computer consulting business, as opposed to trying to limp along with someone internally who just wears the "hat" of the occasional computer person.

One of the most important reasons to bring in a computer consulting business though is that a computer consultant is someone who is an expert in his or her field. This means you can have access to an expert for a fraction of the cost it would take to hire that caliber of professional on a full time basis.

In almost all cases, a computer consultant like this can troubleshoot problem much faster and much more effectively than your internal employees.

A Fresh Computer Consultant Perspective

A computer consultant or computer consulting business can also being in a fresh perspective to your company.

It's often really helpful to have a fresh set of eyes to look at your company and its IT infrastructure. Over time, non-technical small business owners and managers have a tendency to see the same things within their own companies. A good computer consultant or computer consulting business brings a new and fresh perspective into your situation and can help you truly visualize the forest through the trees.

How Computer Consulting Businesses Help

A good computer consulting business or computer consultant is prepared to do any number of things to help your company make the most out of any business or technology challenge it faces. This may include personal coaching, training for small and large groups of employees, and leading strategy-planning meetings with key people... almost as if that computer consultant were your part-time chief information officer (CIO).

The best computer consultants will not enter into your company with a preset plan, but rather will tailor a plan according to the specific needs of your company. A good computer consulting business will have computer consultants on their staff who can quickly find out what the needs of your company are and then come up with cost-effective solutions.

Computer Security, Viruses And Threats

Today, many people rely on computers to do homework, work, and create or store useful information. Therefore, it is important for the information on the computer to be stored and kept properly. It is also extremely important for people on computers to protect their computer from data loss, misuse, and abuse.

For example, it is crucial for businesses to keep information they have secure so that hackers can't access the information. Home users also need to take means to make sure that their credit card numbers are secure when they are participating in online transactions. A computer security risk is any action that could cause loss of information, software, data, processing incompatibilities, or cause damage to computer hardware, a lot of these are planned to do damage. An intentional breach in computer security is known as a computer crime which is slightly different from a cybercrime. A cybercrime is known as illegal acts based on the internet and is one of the FBI's top priorities. There are several distinct categories for people that cause cybercrimes, and they are refereed to as hacker, cracker, cyberterrorist, cyberextortionist, unethical employee, script kiddie and corporate spy.

*The Hacker.

The term hacker was actually known as a good word but now it has a very negative view. A hacker is defined as someone who accesses a computer or computer network unlawfully. They often claim that they do this to find leaks in the security of a network.

*The Cracker.

The term cracker has never been associated with something positive this refers to someone how intentionally access a computer or computer network for evil reasons. It's basically an evil hacker. They access it with the intent of destroying, or stealing information. Both crackers and hackers are very advanced with network skills.

*The Cyberterrorist.

A cyberterrorist is someone who uses a computer network or the internet to destroy computers for political reasons. It's just like a regular terrorist attack because it requires highly skilled individuals, millions of dollars to implement, and years of planning.

*The Cyberextortionist.

The term cyberextortionist refers to someone who uses emails as an offensive force. They would usually send a company a very threatening email stating that they will release some confidential information, exploit a security leak, or launch an attack that will harm a companies network. They will request a paid sum of money to prevent the threat from being carried out, a bit like black mailing.

*The Unethical Employee.

An unethical employee is an employee that illegally accesses their company's network for numerous reasons. One could be the money they can get from selling top secret information, or some may be bitter and want revenge.

*The Script Kiddie.

A script kiddie is someone who is like a cracker because they may have the intentions of doing harm, but they usually lack the technical skills. They are usually silly teenagers that use prewritten hacking and cracking programs. *The Corporate Spy.
A corporate spy has extremely high computer and network skills and is hired to break into a specific computer or computer network to steal or delete data and information. Shady companies hire these type people in a practice known as corporate espionage. They do this to gain an advantage over their competition an illegal practice.

Business and home users must do their best to protect or safeguard their computers from security risks. The next part of this article will give some pointers to help protect your computer. However, one must remember that there is no one hundred percent guarantee way to protect your computer so becoming more knowledgeable about them is a must during these days.

When you transfer information over a network it has a high security risk compared to information transmitted in a business network because the administrators usually take some extreme measures to help protect against security risks. Over the internet there is no powerful administrator which makes the risk a lot higher. If your not sure if your computer is vulnerable to a computer risk than you can always use some-type of online security service which is a website that checks your computer for email and Internet vulnerabilities. The company will then give some pointers on how to correct these vulnerabilities. The Computer Emergency Response Team Coordination Center is a place that can do this. The typical network attacks that puts computers at risk includes viruses, worms, spoofing, Trojan horses, and denial of service attacks. Every unprotected computer is vulnerable to a computer virus which is a potentially harming computer program that infects a computer negatively and altering the way the computer operates without the user's consent. Once the virus is in the computer it can spread throughout infecting other files and potentially damaging the operating system itself. It's similar to a bacteria virus that infects humans because it gets into the body through small openings and can spread to other parts of the body and can cause some damage. The similarity is, the best way to avoid is preparation. A computer worm is a program that repeatedly copies itself and is very similar to a computer virus. However the difference is that a virus needs to attach itself to an executable file and become a part of it. A computer worm doesn't need to do that, it copies itself to other networks and eats up a lot of bandwidth.

A Trojan Horse named after the famous Greek myth and is used to describe a program that secretly hides and actually looks like a legitimate program but is a fake. A certain action usually triggers the Trojan horse, and unlike viruses and worms it will not replicate itself. Computer viruses, worms, and Trojan horses are all classified as malicious-logic programs which are just programs that deliberately harm a computer. Although these are the common three there are many more variations and it would be almost impossible to list them. You know when a computer is infected by a virus, worm, or Trojan horse if your computer displays one or more of these things:

* Screen shots of weird messages or pictures appear.

* You have less available memory than you expected.

* Music or sounds plays randomly.

* Files get corrupted.

* Programs are files don't work properly.

* Unknown files or programs randomly appear.

* System properties fluctuate.

Computer viruses, worms, and Trojan horses deliver their payload or instructions through three common ways.

1 - When an individual runs an infected program so if you download a lot of things you should always scan the files before executing, especially executable files.

2 - When an individual boots a computer with an infected drive, so that is why it's important to not leave removable media in your computer when you shut it down.

3 - When an unprotected computer connects to a network. Today, a very common way that people get a computer virus, worm, or Trojan horse is when they open up an infected file through an email attachment.

There are literally thousands of malicious logic programs and new ones come out by the numbers so that's why it's important to keep up to date with new ones that come out each day. Many websites keep track of this. There is no known method for providing 100% protection for any computer or computer network from computer viruses, worms, and Trojan horses, but people can take several precautions to significantly reduce their chances of being infected by one of those malicious programs. Whenever you start a computer you should have no removable media in the drives. This goes for CD, DVD, and floppy disks. When the computer starts up it tries to execute a boot sector on the drives and even if it's unsuccessful any given virus on the boot sector can infect the computer's hard disk. If you must start the computer using removable media for any reason, such as when the hard disk fails and you are trying to reformat the drive make sure that the disk is not infected.

How can you protect your computer?

The best way to protect your computer from any of the above is by using good quality internet securities software. Purchasing this from a reputable security company is recommended to ensure that your software is kept up to date with the most recent virus signatures. If you are not up to date an unrecognized virus will not be stopped by the software. A full security package will protect you from viruses, Worms, Trojan horses, key loggers and will detect when a hacker is attempting to hack into your computer and prevent them from gaining access when you are online or connected to a network. It is not advisable to use a free anti virus service as these do not provide adequate protection and are a false economy. Recommended internet security software companies are:- Norton, McAfee and others.
