What Our Clients Say

  • Saved my WEDDING!
    Residential Client

    This past year I have been planning my wedding, and I have a ton of spreadsheets and documents on my computer pertaining to the “big day”.  I saved everything on an external hard drive just in case. One day I went to get one of the documents off of the hard drive and of course there were no documents in the file. My computer is very old so I have worried about it crashing. I have no clue where to take it to find out what went wrong. I was telling my cousin Steve Turner about it and he suggested Decatur Computers. I took it in, I was only there for about 10 minutes, they had great customer service, said that they would call me in a few days to let me know what they were able to do. I got a call that week, they not only retrieved everything on the hard drive but they also increased the speed of my computer so we were able to wait a bit longer to buy a new one. I would definitely recommend anyone to Decatur computers.

  • These guys do a great job!
    Residential Client

    "These guys do a great job! I took my computer in to be updated and they not only did that but they got rid of all the bugs and viruses and it runs much faster. Then when I got home with the upgrade my printer wouldn’t connect. I called them up and they connected to my computer from their location and within half hour they had me back in service!  It was also kind of funny watching them move the mouse and different things going on the screen while I was sitting here not moving a thing. :)"

  • Excellent service

    Decatur Computers has given us excellent service in our computer needs. The staff provides professional, immediate service.

Encrypt and Protect Your Data with a VPN

There is fortunately a relatively simple means of doing so, through a virtual private network. You may have heard of virtual private networks, or VPNs, during the debate on net neutrality and the Federal Communications Commission’s verdict. Many plan to thwart the FCC’s plans to give Internet Service Providers the power to sell their users’ browsing habits to advertisers through the use of VPNs. In addition to defying the loss of net neutrality, VPNs can play a key role in your business and its security.

A VPN works by encrypting data as it is sent to and from important assets on a given network, including the Internet. The data is jumbled while in transit, so if it is intercepted, all the interceptor would see would be a jumbled mess of letters, numbers, and symbols. This renders the stolen data effectively useless to the thief, as the time it would take to manually decrypt the data makes it no longer worth it. With a VPN installed on your device, both the data you send and the data you receive is protected by military-grade encryption.

It might be helpful to picture the data you send as a letter, but instead of just sending your letter unprotected and vulnerable, you’ve locked it in a special box. This box can only be opened by another with the key, so if the box were to be intercepted in transit, the thief wouldn’t be able to open it. As a result, your letter to your friend is still safe.

It is for this reason that a VPN can help protect a business from data loss of any size. A word of warning, however: you will want to utilize a VPN that is suitable for use by an enterprise, capable of securing each device on your network. Decatur Computers Inc. can help set your business up with a VPN that suits your needs. To get started, call 217-475-0226.

Tech Term: HTML vs Plain Text

Hyper Text Markup Language (HTML)
HTML is the language used by most web browsers. Basically, it’s the accepted standard for web content. HTML was initially developed by CERN, the European Organization for Nuclear Research, back in the 1980s by Sir Tim Berners-Lee. HTML is the standard by which a browser displays a web page’s content, using tags to determine what exactly is being displayed.

In fact, HTML is the reason why this sentence can be displayed as its own paragraph, separate from the rest of the page.

A web browser looks at the HTML code and translates it into a layout that can easily be read by whoever visits the page. HTML allows for a lot of text customization, including the bold, italic, and underlined text that you might see all over the place. Hyperlinks are just HTML tags that lead to other pages online, as well. You could say that the Internet as we know it today was built off of the concept of HTML.

Plain Text
You can think of plain text as the opposite of HTML. It’s what you get when you get rid of any and all formatting. Punctuation and paragraphing are preserved, but styling is removed, more or less.

HTML is used to create fancy text that is designed to capture attention, whereas plain text is quite simple. Plain text websites barely even exist anymore on the modern Internet, and chances are that they haven’t been updated in years if you ever run into one. They were commonly used over a decade ago when the primary reason to be running them was to embrace slow dial-up Internet connections.

Email Uses
HTML and plain text both have their own specific uses in web design, but they can also both be used in various ways for your email messages. It all depends on what kind of message you want to send. You can use HTML to create something that catches the eye of a potential client or recipient, or you can use plain text to build something simple.

Both HTML and plain text have distinct advantages and disadvantages. HTML can tell a dynamic and visually appealing story, which is great for email campaigns and branding. HTML can also help you track who opens which email, and how often. Despite these great features, HTML messages are also more likely to be flagged as spam or sorted into the wrong folder.

On the other end of things, plain text emails are easy to write, and formatting has never been simpler. These messages can be read on any device, and they rarely run into deliverability problems. However, plain text isn’t as appealing, which makes them easier to set aside and forget about. Plain text also can’t easily be tracked, which means that you aren’t going to know how successful these messages are or how often they reach the intended audience.

Hopefully we have cleared up some of the confusion surrounding these two tech terms. Do you have any that you would like to learn a little more about? Let us know below in the comments.

Email Malware is the New Schrӧdinger’s Cat

Schrӧdinger devised the thought experiment to combat the Copenhagen interpretation of quantum mechanics, which posited that, when unobserved, an object can exist in all states, and reverts to one if observed. In Schrӧdinger’s thought experiment, a cat was hypothetically shut in a box with a small enough amount of radioactive material to only have a 50/50 chance of being detected by a Geiger counter. If it was, a hammer would break open a container of poison, killing the cat. The premise was that, if the Copenhagen interpretation was correct, the cat could be assumed to be both alive and dead simultaneously until it was observed to be one or the other.

While Schrӧdinger’s cat was meant to discredit the Copenhagen interpretation, there is a modern version of this thought experiment that businesses should be concerned about. This version focuses on email, and the attachments that often come with it.

It is no secret that email is a very popular way for cybercriminals and other online mischief-makers to deliver their tools. If we treat emails the way that Schrodinger’s cat was approached, any email could feasibly contain a malicious threat, as well as no threats at all. The thing is, while determining if Schrӧdinger’s cat was alive or dead would be a relatively harmless activity (except potentially for the cat), finding out whether or not an email attachment is infected could cause quite a bit of damage to your system.

Fortunately, there are ways to protect yourself and your system against threats like email malware and phishing attempts. Antivirus and anti-malware scanners can catch many threats on their way in, and a spam blocker can help keep out many more.

If you’d rather know for sure that your inbox doesn’t contain any threats (or dead cats), let Decatur Computers Inc. suggest a few solutions. Give us a call at 217-475-0226.
