Cisco NAC-enabled routers

The recently released Cisco router NAT module enforces NAC at the remote branch locations or ancillary buildings of a campus. Apart from that, the NAC router module also improves the overall security of the network by making sure that all incoming users and devices comply with security policies.

Additionally, the Cisco NAC router module (part # NME-NAC-K9) brings the capabilities of Cisco NAC Appliance Server to Cisco 2800 and 3800 Series Integrated Services Routers. This module helps network administrators by not having to deploy NAC appliances across the board and it helps to consolidate the administrative tasks into fewer boxes.

Amazingly, this module is actually a 1 GHz Intel Celeron PC, with 512 MB RAM, 64 MB of Compact Flash, and an 80 GB SATA hard drive. All that fits onto a single 1 pound module that slides into a router and enforces your security policies. This module requires a 2800 or 3800 series router running IOS 12.4(11)T or later.

Computer Repair

Owing a computer is almost essential in today’s world. With the introduction of the internet and the convenience of email as a method of communication, it’s easy to see why most people want to have a computer in their home or office.

Computers are like anything else and there are times when they don’t operate as planned. It’s frustrating to be sitting at your desk ready to play a game or work on a document only to find that your computer isn’t being cooperative.

When it comes to computer repair it’s often wise to seek out professional help. A computer technician is specially trained to evaluate the problem and offer the best possible solution.

There are certain types of computer repair that you might want to undertake yourself. These are usually minor fixes that can be handled with a bit of instruction and attention to detail.

A computer repair that you might be able to take care of yourself is the replacement of the computer’s battery or fan. Every desktop computer has a fan inside of it. This fan is used to keep the computer’s components cool. It’s essential that the fan operates efficiently to ensure that the computer doesn’t become overheated.

The first sign that your computer’s fan might not be operating properly is that you’ll notice a different sound when you start or run your computer. Instead of immediately taking it to a computer repair shop, take a moment to test the fan.

Computers typically have two fans. One is used to cool the power supply and the other is used to cool the CPU. Open the cover of the computer and listen. If the sound does appear to be coming from the fan that cools the CPU you’ll want to replace it.

If the computer is still under warranty than this type of computer repair will be done free of charge. Follow the instructions you were given for repairs at the time of purchase. If the warranty period has elapsed you can either take it to a computer repair shop or do it yourself.

The very first and most important step when doing any computer repair is to unplug the computer from the electrical outlet. You’ll then need to examine the fan to see how it’s connected. It will probably be attached by a few small screws. Once these are loosened you’ll need to disconnect the fan from its power supply. This will be one or two small clips. Then take the fan to your computer repair shop and purchase a new one.

After replacing it, reattach the cover and plug the machine in. The fan should operate perfectly now and the noise that you were hearing will have disappeared.

Sometimes a computer will make noises because a piece of hardware isn’t attached properly. One of the likely culprits is the CD-Rom or DVD drive. Again for this type of computer repair, you’ll want to carefully remove the cover and listen for the source of the noise. After tightening the screws that hold the hardware in place and reattaching the cover, plug the machine in and listen if the offending noise is gone.

When it comes to computer repair it’s important to be safe and thorough. Computers are an expensive investment and keeping them running efficiently is crucial. If you are comfortable handling a small computer repair yourself, give it a try. If you’re not comfortable, take the machine to a local computer repair shop and allow the experts to do their job.

The Truth About Computer Rental

Computer rental is sometimes necessary for people with serious business or personal obligations. When you are on to an important project, responsible for speaking at a business meeting, or perhaps making a presentation, you may suddenly need computer equipment that you do not normally have.

There are many ways to obtain a computer if you need one, and one of the most common ways to do so without having to fork out cash in full is to try a computer rental. Acquiring a computer this way has a lot of benefits, that you might be unaware of, so check out why it is a good idea to use a computer rental, even if it’s not your first time owning one.

Many places online as well as stores in your local hometown area have the option for computer rental. In fact you can also rent other utilities for your house, apartment or dorm pretty much like furniture or even household appliances like a washing machine, dryer and dishwasher. The advantages for doing this are numerous, and most people are surprised to learn that computer rental is so commonly adopted by many. In fact, you should scout and shop around for the best deals each store has to offer, given the competitive market.

Almost all stores have incentives to use their electronics rental service. One of the best is that if you’ve got a few credit problems, or if you’re trying to establish credit, then this is ideal. There are no credit checks, and you don’t even have to put up collateral to obtain it. All you need is a couple of personal references, and you must be currently employed in order to qualify for a computer rental. 90 days same as cash is an option. Interest is not added because payments are not required; all you’ll be paying for is the tax on your purchase.

The payment period is usually pretty flexible. Stores will work out a set payment plan that is ideal for you. Monthly, weekly, or even every other week is a viable payback time period. Hidden fees are not included because they’re typically figured into the payment plan.

Another benefit is that you will get the computer the day you order it. Also, stores today don’t carry off the wall brands that don’t work half the time, if at all. All reputable stores offer a guaranteed satisfaction, or you’ll get your money back on the payments for the computer rental you’ve made. Make sure to look at how long the offer is for your particular purchase.

The key benefit of getting a home or office computer this manner is that you can always give a go at the policy of trying it before you decide to buy it. With a computer rental you can choose a particular model, try it out for a while, and if you think it’s for you, you can always purchase it. It is definitely a better option compared to buying one outright, and then finding out that it’s not what you really need or want. A computer rental is a win-win option, whatever way you look at it.

Types of Computer Software

Way back in 1946, a German engineer by the name of Konrad Zues developed the world’s first computer programming language called Plankalkül while hiding in the Bavarian Alps waiting for the war to end. Among other uses, Konrad used this table and data structure on his Z3 computer as a chess opponent. You can’t help but wonder if Konrad would feel at ease today with all of the different types of computer software available, or would he go back up into the mountains, play chess and hide from the world.

No matter what your goals, no matter what you’re trying or want to do with your computer (or what you want your computer to do for you), it’s almost certain that there are a variety of different computer software programs to get your project done. One of the most popular software categories of the day is the type that protects your computer from viruses, as just the thought of a virus attacking and impairing your computer from use is enough to make anyone cringe. Anti-Virus software comes in all different shapes, sizes and price points, each offering protection from a vast array of worms, spyware, Trojan horses, as well as the latest in the virus spectrum.
