The Past, Present, and Future of Wi-Fi

If you’re like most people, who have at least one device that uses Wi-Fi to connect to the Internet. We’re well past the days when getting online meant using a phone cable and hearing the screeching sound of a modem whenever you got started. Nowadays, people use Wi-Fi for everything fr om casual Internet use to business networking. Where has Wi-Fi been and wh ere will it be going in the future? This article will explore its past and present as well as things still to come.

A History of Wi-Fi

Wi-Fi was born in 1985 when the Federal Communications Commission (FCC) designated a specific radio frequency for industrial, scientific, and medical use. This frequency was later used by AT&T for cashier systems, allowing stores to tap into their databases through the radio frequency without having to have an actual connection. In Australia, a scientific research project designed to detect exploding mini black holes ended in failure, but the byproduct was a breakthrough in Wi-Fi technology. The Commonwealth Scientific and Industrial Research Organization (CISRO) obtained patents to clear up garbled radio signals from the experiment, and a broader online application was discovered in the process.


Technology: Are You Trying to Outsmart The Recruiter?

This is a guest post by Nancy Anderson at

A technology recruiter can be your biggest ally during your job search, but you must build a good rapport and avoid damaging it with any of the common mistakes made by job applicants. When applying for tech jobs, it is important to make yourself look like the best candidate, but it is also crucial that you don't resort to tricks and unsavory tactics. Avoid using these tactics in your job search, as they could hurt your chances of landing the job you really want.

Resumes with inaccurate information are red flags for a technology recruiter, as inflating past job titles and making your duties sound more important than they really are makes it look like you are lying to get the job. Chris Fields once saw a resume with the title "Senior-Junior IT Associate," which was a red flag because it didn't make any sense. You can use action verbs and strong writing to convince a technology recruiter to interview you, but you should never use fake job titles or exaggerate the importance of the duties you performed in past positions.


Telecommuting: When and How to Use It

Have you ever wanted to work from home? These days, it’s much easier and more common than you might thing. Telecommuting is an arrangement that your company might make with certain employees in which the employee does not physically travel to a specific office but instead works remotely. Telecommuting should be handled carefully, however, as some issues can crop up. The best way to handle this is outlined below.

Pros and Cons of Telecommuting

Telecommuting is a very good way to maximize the productivity of certain employees. Rather than pay somebody for the hours they spend at a desk, a worker instead receives payment based on work that gets done. It can also be very useful for employees who need to balance their work with a complex family life or difficult schedule caused by illness and treatment. On the other hand, the negatives of telecommuting include a loss of routine, since the remote user isn’t necessarily available at all times during the business day. Remote users also get less interaction with colleagues, which can negatively impact those whose positions require a constant flow of discussion and exchange of ideas.


A Complete Overview of Network Address Translation

Did you know that there is a way to convert your entire network to only one IP address? This method is known as network address translation, or NAT. That is only one use of the technology, however. It can also increase security and provide a smoother overall browsing experience depending on how it is used. This article will discuss the history of NAT and both the advantages and drawbacks of using it for your business network.

The History of NAT

NAT originated as a result of how the Internet in general and IPs specifically work. Any computer that accesses the Internet needs to have an IP address in order to do so. Because IP addresses have a limited number of digits, there are only so many of those addresses to go around. While this wasn't an issue in the early days of the Internet, it became an issue later on. As a workaround for this problem, NATs were born. Using an NAT means that your entire network has one IP address, through which many different computers can access the Internet. This limits the number of existing IP addresses that get used and can also have several security benefits when implemented properly.


Backing up Data on a Small Network: Dos and Don’ts

Backing up your data is important, and handling data on a small network presents unique challenges. Rather than try to handle a small network in a way that isn’t custom tailored to your needs, it’s better to put together a customized protocol. When you’re planning out the data backup on your small network, keep the follows dos and don’ts in mind. This advice will help save you a lot of headaches in the long run.

Do: Thoroughly Analyze your Network

Before you get started, you first need to analyze your network and decide exactly where the important data is. You should identify what data is important enough to be backed up, which computers create the most important data, and where this data is stored. This will allow you to quickly identify what areas need to be backed up regularly and what areas you can leave under the supervision of individual employees. Many small businesses try making a backup of everything on the network and either run out of space or wind up with a situation where they can't quickly identify the most important files that they need access to. Analyzing the network beforehand will avoid this problem.


Performance Problems and how to Overcome Them

There are many performance pitfalls out there that can slow down your network. Fr om poor hardware configurations to incompatible software, these items can make even the most modern computer feel like it's stuck in quicksand. Below you'll find a listing of the most common slowdown problems that networks face and what you can do to prevent them. With a few simple steps, you can make sure that your network remains running optimally at all times.

Hard Drive Usage

Your computer's hard drive has a limited number of space, and even the largest of hard drives can fill up very quickly. If you have more than 80% of your hard drive filled with data, your computer and thus other computers on the network it is linked to will have trouble accessing that data. This will cause severe slowdown. Downloading files from the Internet also takes up more temporary space than the actual program itself, meaning that even if you think you are under this lim it you might be causing temporary slowdown by accessing large files. Avoid this problem by storing data on network drives instead of individual computers that have less space, and expand your network space regularly to keep free space.
