Technology classes will prove to students that some hardware and software packages, such as those Cisco creates, are not so easy in learning. Cisco has created some of the best routers, switches, and programs in the world- but learning how to use them has proved to be a task.

Having a poster in your room or home office is a great way to become familiar with Cisco products. When you are looking at the poster a little bit each day, its contents are eventually going to “rub off” on you. Find a Cisco poster that covers different hardware models, or maybe one that lists the different commands found in the Cisco IOS and software programs they have.

Cisco also has great software utilities that can guide you through the process of learning how networks operate. Packet Tracer is their flagship software suite, which is only offered to those who are either in the Cisco Academy or have been in the past. This free program is a godsend for teachers, who are able to easily create labs and print them off for students.

Every work station and student computer should have a copy of a Cisco dictionary on it. This software outlines all of the Cisco software commands, yet also explains what they do and gives examples of usage. It’s an invaluable tool that is free for everyone. It only takes a minute to do a quick search in the dictionary for a term you need, research it, and implement it into your network.

Books are another route to go. Books are the best option for when you just want to sit down and study, but aren’t so good for when you need a quick answer. Students find that books are the better choice, as they are able to go into detail on explaining how Cisco products work in different conditions. For the workplace they are fine to have around, but are often less easy to use than the Cisco dictionary software programs available.

If all you need is a quick reference, consider using the help tool in the Cisco IOS. This help tool will quickly show you different commands that you are able to use, show how to use them, and give a brief description. It will not teach you how to use the commands in detail, so you will need to consult an expert or book for that. The in-program help feature is best suited for someone who might have forgotten a simple command.

Closing Comments

Cisco runs a complicated business, and those who work with Cisco products need to know how to operate within the Cisco software and hardware suites. Keep these tips in Cisco reference materials in mind so you won’t be at a loss next time you are in need of help.

Electronics have evolved quite a bit since the 1980’s, when electronics displays really started to make their mark on the world. It’s interesting to see the hardware and electronics behind each evolution, as we can use it to better understand where the industry came from and where it’s going.

The liquid crystal display, or LCD, has been around for decades. Even in the 1970’s, there were innovative electronics devices that made use of monochrome colors to display basic data. As the industry was still relatively new to the consumer market, most of the displays were only put into the likes of calculators and other basic objects.

The high end televisions of today use plasma technology. It’s funny to think that this technology was one of the first innovations in display technologies- and was around back when computers could only display one color! The technology may not have been as advanced back then, as the computers that used them might only display the color green or orange. Today plasma screens can use millions of different colors.

Recent energy-efficient movements have made the LED quite popular. The light-emitting diode is a display that is incredibly energy efficient, but is limited in what it can be used for. The average LED is used in basic light operations- perhaps for an electronic banner or for a light bulb. LED lights are only recently becoming popular with consumers, who like the energy they save and enjoy the longer life span that the lights have as a result of being more efficient.

The cathode ray tube, or CRT, is what fueled much of the evolution of computer displays and television displays. The CRT allowed for great resolution, it was affordable, and it could support a very wide range of colors seemingly in an instant. Even today, the CRT monitor is still in use since they are so inexpensive and can often be found second-hand at garage sales. They may be more bulky than newer technologies, but they work just the same for the average user.

At this point, the industry is looking more at innovation than a way to make current technologies smaller and more efficient. Focus has been put on technologies such as touch capability- which has exploded into the retail market. It has also been used dominantly in the mobile phone market, that has been able to create many innovative mobile phone designs as a result of trends in touch screen displays.

Final Thoughts

Displays will continue to evolve until we see something that can fit all needs. New displays will be more energy efficient, less expensive, support a wider range of functions, and give way to a more exciting time of innovation and inventions that will spur the technology industry completely.

Anyone that owns a website understands the perils of losing a web hosting plan that they have attached to their domains. A web host is absolutely necessary for any domain name to remain hosted on the Internet, so it is crucial that they stay active in order to maintain the website.

Before committing to any hosting plan you should be extra careful when reading the terms of service and privacy policies. If you break those rules set in place by the company, you are at high risk for having your service terminated. This can be potentially dangerous if you run a business or have already built up a strong website. Do yourself a favor, and read the terms of service to avoid being canceled on.

You should also be prepared for the pricing. Sometimes signing up for a discount can be tempting, and you actually get that low price offer. You should also try to get an idea of whether or not you can afford the payments each month after the trial or discount offer ends. Hosting plans will not last unless you cough up the cash for them.

Auto-renewal is also an issue. If the web hosting company cannot auto-renew and you don’t take five minutes out of your day to update credit card or billing information, then your sites are in danger. Sometimes it’s easy for the renewals to slip your mind – especially if you have more than a few websites. If this is a recurring problem for you then it would be best to write down your information and have it on your desk.

If you don’t want to deal with the hassle of an auto-renewal then you can go the route of buying in advanced. Be aware that buying in advanced has its own problems, and you should be prepared for those if they do arise. Advance purchasing can save you a lot of money and time – especially if it prevents you from losing your hosting on your website.

Your last option would be to always have a back up plan. Regularly manually backing up websites and using back up hosting options can prevent you from losing your hard work to a simple error or flaw in the system. Web hosting companies are ran by people that make mistakes – so protect yourself by getting back up options installed and ready to kick in if your site loses its hosting package unexpectedly.

In Conclusion

Even though web hosting isn’t terribly expensive, it isn’t great to lose out on your hosting because of a mistake. Most of the time the above errors do not allow you to get a refund, and if you are eligible for one it will be quite difficult.

Packet Tracer is a wonderful development program put out by Cisco: a leader in computer networking hardware. Creating a basic network can be tough going, but it’s necessary in learning in order to qualify for the CCNA certification exam.

One of the most basic computer networks that you can create involves two computers and a router. Although it would seem simple in connecting the two computers to a router and calling it quits, configuring the Cisco IOS settings actually takes a bit of work. It’s quite unlike a commercial router that is widely available to consumers for home usage.

The running configuration of the router can be accessed by using a console cable and setting up a connection from one of the desktop machines. The console cable isn’t necessary for Packet Tracer, but if you plan on programming a real router you will definitely need one. You will also need a crossover cable so that you may connect the desktop machines to the router’s individual Ethernet ports.

The first step in completing the network is to assign IP addresses to each computer and Ethernet interface on the router. You should have two separate networks: one for each computer and interface. The interface and computer for each network should have different IP addresses, giving you a total of four IP addresses to assign. The Ethernet interfaces are assigned in the Cisco Command Line Interface, while the desktops must be configured separately.

After configuring the IP addresses, you will need to configure what is called a gateway address. The gateway address is simply the IP address of the Ethernet port that a computer is connected to. The gateway tells a computer where to send and receive information that comes across the network. This address is edited on the desktop in the IP address settings. Without it, information would never reach its target destination.

Last, we get to test the network we just created. By sending a packet of data through a ping, we can verify that one computer can contact another computer on a completely different network. From one computer, type in the ping command and the IP address of the separated computer. If the result times out, it means you have either configured the router improperly or have faulty cables. You will find that most often it’s a problem regarding cables and network topology.

Closing Comments

The small network described is functional, and is even used in real world applications. Using Packet Tracer will simplify the process of designing the network so that you can save time in the overall process, and put more time into troubleshooting and problems that arise during the course of the implementation.

The CCNA course offered by Cisco is one of the toughest courses a college student can take. It demands mastery of hardware and software that the student may not have outside of the classroom. As a result, students are looking towards Cisco network emulation software more now than ever, so that they may make the grade.

An expensive yet thorough solution is with Boson’s software packaged named Netsim. Netsim ranges in value, from $200 to $500, depending on the licensing and options needed. Netsim is the best bet for instructors, as it comes loaded with plenty of extras such as activities and grading programs. Perhaps less affordable for students, who are usually on a tight budget.

Open source programs should receive the attention of students since they are free to download and use. Dynagen is one such program, of which is built with the Dynamips simulator. Dynagen is one of two software packages that currently works with Dynamips, and is often described as being the less friendly of the two. Documentation is also lacking for those with questions.

Another open source program that works based on Dynamips is GNS-3. This program package is more user friendly than Dynagen, and it also has a more supportive user base. One can easily browse the forum associated with the website and get instant support. GNS-3 is free to download and use, so students should at least give the program a try when deciding on which network simulation software to use. Paid programs have free demos to help judge which is best.

Packet Tracer is known to be the king of the industry. Cisco created this software for its own students in the CCNA course. It has the best tutorials, design, and functionality of all the programs listed. The only problem is that if you aren’t a Cisco student, alumni, or instructor- you won’t be able to get your hands on it. You couldn’t get it even if you offered them money; Cisco is strict on only allowing students to get their hands on this fine software. It’s at least worth considering a Cisco class to obtain.

There are several web-based programs used with Macromedia Flash and text-based applications that one can look at. These range from free to pricey, just as standalone programs do. Web-based applications can be just as useful, but keep in mind you’ll have to have a constant connection to the Internet to use most of them. Often times it’s just better to get a desktop application for ease of use.

Final Thoughts

You won’t find a much better network simulation package than Cisco’s Packet Tracer. If you can, find a way to get the program either by enrolling in the Cisco Academy or finding other means of getting it. It’s currently the best there is for learning advanced course materials.

An extended vehicle warranty is a way of protecting your investment in a vehicle. If it were to break down, you wouldn’t have to foot the bill of repairing it. It’s a nice feeling to feel secure, but for some, the trade off of paying a monthly premium may not be worth the security.

New cars already come with a warranty, but auto dealerships like to offer an extended warranty to get more money out of car buyers. If you plan on using the amount of miles allowed under the warranty in a quick time period, the extended warranty wouldn’t be such a bad option. Otherwise the factory warranty tends to last a few years at least.

When buying a used car, you won’t get a warranty with it, unless it is still on the factory warranty. Instead you will be presented with the option to buy an extended warranty in which to secure your car. If the car has many miles on it, it is worth the money in most cases. A car make or model that tends to break down more than others will also warrant the need for it.

The smart thing to do before even looking at cars is to research which ones are dependable. A car salesman will lie in order to make a sale, so you should pull your information from the Internet and experiences of people you know. Try to stay with vehicles that have been proven to last a long time, and be efficient for the amount of money that is paid upfront.

Used cars are tough to gauge when deciding if you should get an extended auto warranty. Theoretically, and old car that was not in your possession could break down at any time because you don’t know how it was handled with the previous owners. You can have a mechanic look the car over fairly well before deciding to buy the car or the warranty if you don’t have the expertise to judge the car yourself.

It’s easy to determine an area of time in which a vehicle might break down from natural causes. After the initial factory warranty wears off, there is a prime time thereafter in which the car is likely susceptible to breaking down. It is recommended that through your research, you develop a statistics table of information to help formulate when a good time would be to get an extended warranty.

In Conclusion

Extended car warranties are a great investment if you are tired of worrying about your car breaking down. If you sign on with a good company, you can enjoy having your car taken care of for many years to come without a care in the world.

If a potential client couldn’t locate your business, it’s likely you will be losing out on lost profits. Creating or obtaining a vector based map illustration can make your business location easier to find, and it saves potential clients the time and hassle of obtaining a real map.

The legend is the most important part of your map. Without it, you wouldn’t be able to have a map in the first place! The legend details what the symbols and various shapes you use in the illustration actually mean. That way you don’t have to make your illustration messy with labels and other captioning. A short and to the point legend always makes for a great map.

Contrast is very important when designing your illustration. A viewer should be able to look at a map and depict which colors are assigned to which objects on your map without a second thought. The color design, thus, is just as important as the legend in that respect. Carefully pick our colors, yet also don’t try to use too many colors to represent different things- otherwise you could confuse visitors.

Your map illustration should be seen as a method of branding your business- so also investigate options in creating some form of logo or mascot to include on the map. The ideal logo would be set apart from any other logos or mascots you have seen. Including your logo in the legend as a symbol is another great way to show off your branding while also being discrete about it.

Maps become quickly outdated as new roads are built, buildings are destroyed, and environments change to reflect the construction of cities. It wouldn’t be uncommon to see a map only stay accurate for ten years or so. At that point in time when the map becomes obsolete, you can easily make changes to the map if your designer has provided you an editable map file. Ask what options you would have in making alterations so you can keep current.

Map illustrations do well on a website, where any random Internet user can view a map illustration and find your business. Also put the money forward to get map illustrations out in print- such as in a brochure. An effective brochure will act a lot like a business card, and actually bring you repeat business in many cases. Provide contact information and some business information as well, and you essentially have set yourself up for repeat business.

Closing Comments

There are many steps to go through when developing your own map illustration. Start by finding a designer that can appease your request, whether in your area or through the Internet. Many talented artists can be found using the Internet, and at affordable prices.

A framework is a truly great tool that web developers can use to cut down on the time it takes to create an application, or even an entire website. Frameworks are available for most languages commonly used today, so you won’t have to stray too far from a familiar path.

Just starting out in a framework isn’t easy, but Ruby on Rails has made the process a lot more simple. The Ruby on Rails framework is built on the Ruby language, although it isn’t difficult to understand and pick up if you don’t have prior experience. You will have to do some initial configuration, but if you are a web developer, you should be able to handle it without a problem.

PHP frameworks are numerous. You could spend time learning quite a few PHP frameworks and end up with something you like. One of the most popular PHP frameworks would be CakePHP, which already has books out in local stores such as Barnes and Noble. Amazon also stocks a large inventory of CakePHP books, so getting started wouldn’t be hard at all. CakePHP is better for PHP fans that want a framework that is similar to something they already have experience with.

Saving time is one of the goals of frameworks, but in the case of Django, the framework was created for the sole purpose of meeting deadlines. A lot of time has passed since then, and Django has become one of the most respected frameworks available, and certainly so for the Python language it is built on. Django is an excellent choice if you want a framework that will withstand the tests of time.

Technology will continue to expand in the future years to come. Don’t get stuck with a framework that has ceased to keep up to date on such technologies. Odds are you will have a safe bet with open source frameworks, since they are run by a community and not just a proprietary business. By going for an up to date framework, you won’t have to completely re-haul your website applications once the framework starts to become out of date for a newer age.

Don’t forget that a framework can save you a lot of time. Even if you don’t think you have time to learn a new framework, you would be surprised on how easy you can get started. Setting up the basic configuration for the server and learning new syntax can take as little as a day, depending on the framework you are using. If nothing else, buy a good book and read it in your downtime.

In Conclusion

Web development frameworks can take some time in learning. You should try out a few you think you would like, do a few test applications, and then make an educated decision on which web framework you would like to pursue.

Ad-Aware Pro 2009 is the latest addition to the family of security products that Lavasoft creates. Ad-Aware has a long history of shielding computers from obscene hackers and programs that could cause irreversible damage to both one’s computer and their very identity or life in the process.

Price is the first factor that a computer owner is going to look at. When we can get a free lunch, we take it so long as it is on comparable terms to competitor products. Unfortunately Ad-Aware is considered to be in the upper bracket of security software when it comes to price. As of now, the price is solid at around $40 for a year of coverage and updates. Discounts can be obtained by getting a longer license period.

Unlike some competitors, Ad-Aware Pro 2009 comes with a pop-up blocker. It’s nice to have when browsing Internet websites that believe that the best way to sell a product is to annoy the very Internet users they are trying to convince. Fortunately for you, the pop-up blocker is able to eliminate the majority of such advertisements without blocking legitimate pop-up actions.

The major selling point of Ad-Aware 2009 is the fact that it can stop malware from installing itself before it even gets a chance to infect a computer. This functionality, known as real time protection, can help save your computer against malware that would otherwise cause havoc and potentially ruin your computer. Best yet, the protection gets stronger every day as more types of malware are identified and blocked against.

It shouldn’t be too surprising that a large company like Lavasoft has a lot of questions to answer on a periodical basis. The response time in technical support should, thus, not be considered to be instantaneous. At the same time customers of Lavasoft have voiced their concerns that the response times in recent times has been unacceptable. If you need technical support, you had also better have a fair amount of patience as well.

There are other programs to consider in your purchase decision. You will notice in your comparison that Ad-Aware is of the higher priced programs. It also is more geared towards the technical-savvy in some applications. The extra benefits the program provides the user is worth the price to some, but only if the lack of support isn’t something that isn’t going to bother you. You are able to try it for free among some download mirrors.

Final Thoughts

$40 can be a lot of money for a year of protection, but then again it’s better to pay $40 than to replace a computer that cost over twenty times that amount. Find other programs to compare it to so you make the right decision.

With the costs of cable and digital television going up each year, can you really afford to pay for entertainment that you might not even have the time each day to enjoy? One alternative you have as an educated consumer is to simply watch television shows from your very own computer.

The majority of services that offer online television streaming will operate based on supplying you with a computer program. This software will connect to different resources, pull information on television shows, and allow you to watch them instantly. The software usually comes as a one-time fee, so you will essentially be paying for the software once and enjoy the entertainment for a lifetime.

In addition to saving money on a subscription you would otherwise pay, you will also not have to pay for hardware that you have to buy with digital or cable services. Some pieces of hardware, such as a digital video recorder, can cost several hundred dollars if it has to be replaced or bought outright. Skip the fees and instead use your computer’s own hardware to do so.

You don’t have to stay immobile with your television shows. By all means, put the program on your laptop and take it everywhere with you! So long as you have access to a wireless acess point or satellite Internet, you will be able to watch television shows anywhere you want. Long trips in the car can now suddenly become much more entertaining with the software.

When you switch to online television from your normal provider, don’t start thinking for a moment that you will have to get rid of your television. Instead, just hook your computer up to your TV so that you can transfer the video signal and watch it just like you would any other instance. You must make sure your television and computer has the right inputs and outputs, but most televisions and computers that were made in the past five years should indeed have them.

Buying the computer software you need to watch television on your PC is the next step. The good news is there are quite a few websites offering the service. All you need to do is view their offers, determine which has the best price for what you would like to obtain, and make a purchase. Also consider reading reviews of a service before buying the program.

Final Thoughts

Television shouldn’t be so expensive. After all, we aren’t always able to watch television a lot when our schedules get filled up. Instead you should go the more sensible route and opt for an online television service that doesn’t require a subscription for the television shows you want to watch.
