Computer Technology Diversified Field

history of the Computer and tecnology

The technology of computer science and its development mirrors the growing number of newer fields and many sub disciplines. Generally computer science deals with anything that has to do with computers. However, due to the ultra fast, technical development and rapid growth within the last couple of decades, computer science today covers many more subjects than just computers. There are so many sub fields involved like, general computer science, media informatics, technical computer sciences, networking, internet and such like.

Schools abound that can give you the hands-on training in some of the fastest growing technologies of computer networking and network security, help-desk and technical support, and in computer and network systems administration. Two-year programs may be all that is necessary for some computer technology positions. If Network Security Specialist is your dream job, a degree in computer science can help you ensure that networks are secure from security threats.

If Help Desk Technician is your oyster, a computer technology school can teach all the ins and outs of consulting and customer support. Most computers at this time were termed "mainframes" due to the fact that many computers were linked together to perform a given function. The United States was attributed the title of pioneering the computer. This resulted in newer components and smaller sized computers. Prices dropped dramatically and computers became more affordable to the average household.

Many people say that the predecessor to the computer was the typewriter. Children are being taught basic computer skills in the classroom in order to prepare them for the future evolution of the computer age.

CD DVD Scratch Repair

Many of us by now have probably managed to amass rather large and impressive collections CDs, DVDs and game discs. As these collections age questions of maintenance and recovery from scratch damage arise.

Many scratched DVD discs or other discs can simply be replaced at minimal cost and this holds true for CDs and game discs as well.

However the same can't be said for scratched discs that are original recordings of your own personal memories such as home movies and digital photos stored on discs. Also you may possess scratched games discs, scratched DVDs or scratched CDs that you can't buy any more.

The obvious answer to this is to create backups and copies of these discs before they are subjected to "wear and tear" but sometimes we forget to do that until it is too late!

So what can you do to recover the data from a scratched CD, game disc or DVD?

There are 3 main ways you can approach this problem.

The first and safest method is by using a software solution to the problem.

There are a number of specialist software products available that have DVD error correction capabilities built-in or have been specifically designed for this purpose.

Whether you are successful or not with this method depends on the degree of scratch damage the disc has sustained but it is the best because it doesn't interfere with the surface." Win or lose with this method the scratched disc is exactly the same as it was when you began.

Your second choice is to attempt to repair the CD DVD scratches by hand yourself.

There are many "do it yourself" websites and on-line videos that will show you how to use home products to repair scratched DVDs. You can use toothpaste, Brasso or even Pledge!

There is always the possible problem here of it going wrong in which case things are now worse than when you commenced! Of course if you get it right… you look like a genius!

I look at it this way: If you are the kind of person who can read instructions and follow them TO THE LETTER to get the desired result and also "conceptually" understand WHY it is done that way then you should be fine.

If you have the slightest doubt this is definitely not for you!
The final method of handling CD and DVD scratch repair is by using a CD DVD scratch repair machine.
If the software method or the "do it yourself" method haven't worked then try this final way!
Unfortunately this subject is not a simple as it appears. CD DVD scratch repair devices must perform a pretty difficult job. They are all trying to re-surface a piece of clear polycarbonate plastic to a very high standard so that a laser beam can pass through uninterrupted.
There are lots of inexpensive CD DVD disc repair machines available thet really are a waste of your time and your money.
There are three tiers of machine separated by price range and the truth is that you get what you pay for.
This doesn't mean you have to fork out over $1000 to buy an effective repair machine, but on the other hand obtaining perfect results from a $20 machine is not going to happen!
By far the most effective CD DVD disc repair machines for the home user come in at just over the $120 mark and for that price you can get a very good machine that will handle your discs well.

When Did You Last Test Your Company Data Backup?

Imagine the effect on your business. The IT system fails and everything is lost. Every single document on your network has seemingly gone up in a proverbial puff of smoke and the company is left with nothing – no records of orders, contracts, invoices, vital contacts, staff details, and payroll. Even the emails have simply vanished.

Your IT infrastructure forms the very core of most businesses I this day and age and this does not only apply to multi-national corporations but even the local home office user as well. And if you have not taken sufficient steps to cope with potential data losses then the reality is you could be putting the existence of your business at peril.

Any IT solution should not be restricted to the basics like computer support , but should also take into account business continuity planning.

Danger lurks around many corners ranging from mechanical and electronic failures, human error, to the more sinister employee sabotage and data theft. Even more unpredictable disasters can occur. Many businesses are still reeling from the devastating floods of 2007 – the type of Act of God that can hit any unprotected business.

There is a lot more interest being taken in the topic of business continuity recently, but the implementation of disaster recovery solutions has been pretty hit and miss for many companies and businesses, many of which still rely on aging tape back up technology. One of the biggest failings is testing the system that has been put in place and many companies have felt the pain of the backup simply not being available in their hour of need.

This then leads to the need for far more expensive data recovery or raid data recovery as a method of hopefully retrieving vital data.

Many companies are now investing in remote data backup models as part of their business continuity strategy as these have a number of significant advantages.

For example, remote backup does not rely on restoration from tape devices, but instead lost data can be accessed almost immediately directly from a secure location regardless of the time of day or even where you are trying to access the data from. So there is no worry that the backup did not work or the tape was possibly faulty, or even that the backup device has failed and you can’t get a model that can read your tapes.

If you have not yet implemented a disaster recovery plan for your business then you should put this high on your business agenda. Could your business survive if it were to lose all the client records on your CRM system or financial data from your accounts package. Don’t forget the cost is not purely the loss of data but also the lost business that may ensue as well as the time and resource to get things back on track.

And of course on a final note, once you have implemented a business continuity plan make sure you test it to make sure the plan is robust in a real environment.

The Conficker virus is the latest of major threat viruses to computer security.

Computer viruses can cause all types of havoc, including destruction of vital processes and data.
Rootkits

Rootkits are very dangerous because they can hide from innefective virus software and the user. Rootkits create stealth program codes that run at a lower level than the user can see with most below average anti virus software.

Since not all anti virus programs are capable of protecting against rootkits it is important to look for such protection when considering a computer security suite.
