    Most broadband Internet connections stay "always on" - keeping you online at all times. Home network owners often leave their router, broadband modems and other gear powered up and operating constantly, even when not using them for long periods of time, for the sake of convenience. But is it really a good idea to keep home network equipment always connected? Consider the pros and cons. Advantages of Powering Down Home Networks Security: Powering off your gear when not using it improves your network security. When network devices are offline, hackers and Wi-Fi wardrivers cannot target them. Other security measures like firewalls help and are necessary but not bulletproof. Savings on utility bills: Powering down computers, routers and modems saves money. In some countries, the savings is low, but in other parts of the world, utility costs are significant. Surge protection: Unplugging network devices prevents them from being damaged by electric power surges. Surge protectors can

    Leave your computer on all the time, or shut it off when it's not in use; does it really make a difference? If you've been asking yourself this question, then you'll be happy to hear that you can choose whichever way you want. You just need to understand the ramifications of your choice, and take a few precautions to ensure you get the longest life you can from your computer. The most important precaution is to add a UPS (Uninterruptible Power Supply), no matter which method you choose.  A UPS can protect your computer from many of the dangers it's likely to face. The Things That Can Harm Your Computer All of the parts that make up your computer have a limited lifetime. The processor, RAM, and graphics cards all experience aging caused by, among other things, heat and temperature. Additional failure modes come from the stress of cycling a

    As outlined in the Adobe Support Lifecycle Policy, Adobe provides five years of product support from the general availability date of Adobe Acrobat and Adobe Reader. In line with that policy, support for Adobe Acrobat 11.x and Adobe Reader 11.x will end on October 15, 2017. What does End of Support mean? End of support means that Adobe no longer provides technical support, including product and/or security updates, for all derivatives of a product or product version (e.g., localized versions, minor upgrades, operating systems, dot and double-dot releases, and connector products). What should I do now? You may continue to use Acrobat XI and Reader XI, but Adobe will no longer provide any updates or address any existing bugs or security issues in the software. Because of this, it is strongly recommended that you update to the latest versions of Adobe Acrobat DC and Adobe Acrobat Reader DC. This will ensure that you benefit

    The latency of a network connection represents the amount of time required for data to travel between the sender and receiver. While all computer networks possess some inherent amount of latency, the amount varies and can suddenly increase for various reasons. People perceive these unexpected time delays as lag. The Speed of Light On a Computer Network No network traffic can travel faster than the speed of light. On a home or local area network, the distance between devices is so small that light speed does not matter, but for Internet connections, it becomes a factor. Under perfect conditions, light requires roughly 5 ms to travel 1,000 miles (about 1,600 kilometers). Furthermore, most long-distance Internet traffic travels over cables, which cannot carry signals as fast as light due to a principle of physics called refraction. Data over a fiber optic cable, for example, requires at least 7.5 ms to travel 1,000 miles. Typical Internet Connection

    Whether you're a home PC user or a network administrator, you always need a plan for when the unexpected happens to your computers and/or network. A Disaster Recovery Plan (DRP) is essential in helping to ensure that you don't get fired after a server gets fried in a fire, or in the case of the home user, that you don't get kicked out of the house when mamma discovers you've just lost years worth of irreplaceable digital baby photos. A DRP doesn't have to be overly complicated. You just need to cover the basic things that it will take to get back up and running again if something bad happens. Here are some items that should be in every good disaster recovery plan: 1. Backups, Backups, Backups! Most of us think about backups right after we've lost everything in a fire, flood, or burglary. We think to ourselves, "I sure hope I
