About Cheap Computer Motherboards

Motherboards that have various peripherals built into them are very popular these days and are a good buy. If you are not a high end gamer or you are not going to be setting up a sound studio, onboard audio is a good way to save a few bucks. The same goes for an onboard modem if you need a dial-up internet connection and onboard ethernet if you need networking for LAN.

In my personal and professional experience, motherboards that have most peripherals built into them work very well even for gamers unless you need a special feature. The exception to this rule is onboard is video. Even the famous ATI Radeon and nVidia Geforce GPUs (Graphics Processing Unit) that are built onboard perform poorly.

If you use your computer mostly to surf the net and use office applications, onboard video is the way to go. If you are an avid gamer or you create video intensive media, you will want to use a faster, more powerful, add-in video card. You know who you are.

Warning: Be careful when buying a cheap motherboard like Biosta... I strongly advise purchasing a name brand motherboard. A cheaply built motherboard is not cheap; it will cost you later in frustration, heartaches, headaches and maybe even replacing it. An inferior motherboard can cause unexplainable system crashes, driver problems, the Windows "Blue Screen of Death" and a worthless warranty. Remember, the motherboard is the heart of your system and if you look around you can find a good name brand motherboard with all the bells and whistles for $100 or less.

My top 5 motherboard manufacturers are: ABIT, AOpen, ASUS, Gigabyte and MSI. Not necessarily in that order. Choose your motherboard for features first and brand second. This is by no means a definitive list there many good motherboard manufactures.

POWER

Mobile phones are generally obtaining power from batteries which can be recharged from mains power source. previously, the most common form of mobile phone batteries were nickel metal-hydride, as they have a low size and weight. Sometimes lithium-Ion batteries are used, as they are lighter and do not have the voltage depression that nickel metal-hydride batteries do. Many mobile phone manufacturers have now changed to using lithium-Polymer batteries as to oppose the older Lithium-Ion, the main advantages of this being even lower weight and the possibility to make the battery a shape other than strict cuboid. Mobile phone manufacturers have been experimenting with alternate power sources, including solar cells etc….

In addition to the battery, most cellphones require a small microchip, called a SIM Card, to operate.. Approximately the size of a one-cent postage stamp, the SIM Card is installed underneath the battery in the rear of the unit, and stores the phone's configuration data, and information about the phone itself, such as which calling plan the subscriber is using. When the subscriber removes the SIM Card, it can be re-inserted into another phone and used as normal this can be done easily..

Each SIM Card is activated by a unique numerical identifier ; once activated, that identifier is locked down and the card is permanently locked in to the activating network. Sim cards plays a major role in the mobile phones….
