For server administrators, patch management can be a way of life. But for home users, patch management is a distant thought in most home computer users. Knowing when to patch products and how often patches need to be applied are some of the questions that most home users never think about. Knowing what to patch and when can make a difference in the security of your home computer or network.Automating Patch ManagementMore and more programs are now offering auto update of their software. Applying patches every time the program needs to be updated. Although these updates dont always mean it is for the sake of security, a security patch may be issued along with the update. Microsoft Windows now offers windows updates automatically. So updating windows is easier than ever when users choose this option.Problems with PatchesOne problem with patching software is breaking other programs. This is usually only the case with updates from larger programs that other programs hang on. Such as operating systems, anti virus software, etc... Smaller programs that other programs dont rely on are usually immune from this. During automated patch management, this may happen and you dont realize it has happened. The problem can be combated with manual patches, but knowing when and what to patch may be a hassle for home users.What to patchAny program that acts as server, accesses the internet are all avenues for attack. These programs need to be patched if one is available. Smaller programs that dont access the internet or dont have any real threat outside the current working environment may not need to be patched, as most of these programs will not have patches available. Programs like email, internet explorer, firefox, etc. need to be patched if one is available. These programs that access the internet need patches as new vulnerabilities arise for these programs regularly.Smaller programs like solitaire or notepad that dont have internet access will not need to be updated. Although they may be updated when another patch is available for larger programs such as an Operating System patch. Usually when this happens, the patch to fix a problem with the larger program breaks the smaller program. And a patch must be applied to it to fix potential problems.When to Patch?It's a good idea to check for patches to your software products at least once per month. If you use your computer on a daily basis, or the computer stays online constantly, such as with high speed connections, you may need to opt for a stricter schedule on patches. Such as weekly or bi weekly. Of course, using automated patch management software can eliminate this need for such time consuming tasks.As mentioned, automating patch management can save much time and energy. Check with your software vendor for information on when patches are usually available. And also check if the program offers automatic updates to its software. This mundane task can be handled with little user intervention and may be possible to run at times when the computer is idle or late at night when it is not in use and doesnt restrict your browsing bandwidth.So keep your programs running smoothly and updated often. Remember the saying, an once of prevention is worth a pound of cure. This applies to computer security and patch management also. Dont let your program cause problems just because you forgot to install the latest patch. You'll be glad you did.
In recent years, laptop computers have become much more popular than desktops, especially among students. It is estimated that well over 90% of college students that own a computer will buy a laptop instead of a desktop. The advantages of portability and the growing number of available wireless internet hubs make this an easy choice.The downside of buying laptops is that they are generally much more expensive than desktop computers that have the same amount of power and memory.Fortunately, this is one area where college students can easily save a lot of money. Many laptop computer manufacturers, such as Dell, HP, and Gateway, all have a wide selection of used laptop computers which are refurbished and resold at prices much lower than you would pay for a brand new notebook. Although they are used, they have been refitted and re-inspected by the manufacturer and even given a warranty that usually covers the first 90 days after purchase.At todays prices, its hard to find a new laptop computer for less than $750, and even then you are buying the cheapest model with the smallest screen size and minimum amount of power. To get a bigger screen, more memory, and more processing speed, you can easily end up paying from $1,000 to $2,000 or more for a new laptop.With a used laptop, you can get the same power and screen size of the pricier new laptops without paying the higher price. The lower-priced used laptops can range from $300 to $800, and these arent weak little Celerons or Semprons. At this price range, you could be getting a Pentium M, Centrino, Core Duo, or Turion 64 with 512MB to 1GB of memory and at least a 14 screen. Used laptops in the $300 to $800 price range also typically have a hard drive with 30 to 120 gigabytes of space, plus a preloaded operating system, such as Windows XP or Vista. Brand new laptops with the same specifications would easily cost two or three times the price of a similarly-equipped refurbished model.So, if youre looking for areas to save money as you head off to college, start by buying a refurbished used laptop instead of a brand new one. Youll be walking around campus with a very capable computer for your college studies, except youll have a few hundred extra dollars left over for other expenses.

Digital sensor is an important matter of consideration for a digital camera owner. The quality of the photography depends on the size of the sensor. The larger the sensor the better will be the quality of the photograph. This fact plays a vital role in choosing the perfect "digital camera" .The size of the sensor affects digital photographyThe final image is an outcome of the various pixels that are arranged by the sensor of the camera. Soon after clicking on the shutter button, the pixels start to accumulate the photons in a cavity. After completion of exposure, camera confines those pixels and find out the number of photons that are attached to each other. Now these photons are compiled in accordance with the levels of intensity. But all these can only give you a colorless image. There are some filters on the cavities that release the specific color of light into those cavities. All the contemporary digital cameras are unable to capture all the three primary colors. Only one of the three primary colors gets into each cavity. Thus the camera needs to estimate the remaining two colors to get the adequate information about all the three colors at every pixel.Bayer array is one of the commonest color filters used in digital cameras and passes on all the information about different primary colors to each pixel. Higher or lower resolution of photograph depends on the array.In a very precise meaning a sensor is a silicon semiconductor meant for acquiring photons and converting them into electron. The size of the sensor is, perhaps, the second most important thing just after the quantity of mega pixels. Though the size of the sensor has a huge range, generally it is of two basic categories. The sensor of DSLRs comes under the range of 24x16mm to 36x24mm, but it remains of the range of 8x6mm in the case of a consumer camera. The size of the sensor affects the performance of the camera and decides the intensity of sensor produced noise. Noise, actually, worsen the images of digital camera. If the sensor is smaller than actual requirement, then the camera is unable to capture the full view of the image. Fisheye lens can actually compensate this to some extent. But one, who really does not want to compromise with the quality of the image, should only go for the camera having adequate size of sensor. In case the sensor is small, centre of the lens captures the image. Since maximum portion of the image passes through the centre of the lens, quality of the lens becomes very important factor to consider. The quantity of light that reaches into the pixel is very less. Therefore useful image is only available after proper enlargement of the same.There is a relation between sensor and crop factor. In this case, because of limited size, while using 35mm lens, the sensor crop out the inferior quality portion of the image. This is simply because the fact that the image passes through the centre of the lens in case of smaller sensor and the image remains sharpest at that position. The use of lens becomes a meaningless practice if the sensor of the camera is undersized. But a 2/3 or even size can give optimum output if it is used with a 35mm lens.In upshot, it can be concluded that finding out a pixel pitch of a given sensor, while buying a digital camera can be tricky. However, one can seek the help of certain review sites that provide the information about recent models including their sensors.
