System board or motherboard is the PCB that connects all the system components together. In today's computers, motherboard is a crucial part of the system and it holds many important components required for the functioning of the system.
A lot of components are soldered in to the motherboard during manufacturing. These components include video cards, bios, controllers and many others. A motherboard like a backplane provides electrical connection for the system devices to communicate with each other.
The motherboard also contains expansion slots or pci slots which can be used to enhance and increase the functionality of the system. The motherboard in computers manufactured by apple are called logic boards. Some computer systems are single boarded with no external connections. Such systems include kiosks, industrial control interface etc. They do not have any slots or do not support slots for expansion. These single board computers cannot be customized once manufactured.

Computer RAM Memory and Its Significance
Computer RAM or random-access memory is one kind of computer memory that can be used indiscriminately. It acts as the main memory of the computer system. It allows accessing any byte without the interference to its prior bytes. It is mostly the common type of memory used in computer systems and sometimes in printers. Generally, two types of RAM are available, namely- DRAM or Dynamic random-access memory, and the other is SRAM or Static random-access memory.
DRAM is widely used because of its availability and cheap cost, while SRAM is relatively expensive but faster than DRAM. For DRAM, it is necessary to refresh the system continuously whereas, SRAM doesn’t require any refreshing. Moreover, the data transfer rate is faster in SRAM rather than DRAM. However, you should pick your desired RAM according to your budget.

Plasma TV's Better Than LED TV's?
LED TV’s are in trend and have greater demand from buyers compared to Plasma TV but what they do not know is some characteristics of Plasma are vastly greater than LED. One is the quality of color being produced. LED TV uses LED backlight arrayed for a brighter color of the image seen on the screen but the downside of it is the dimming color which gives a grayish shade in a supposedly black colored portion of the image but Plasma almost perfectly gives the right shade of blackness in the image to provide a more accurate view and scene. Another characteristic is the Plasma’s price. It is less expensive than LED and not all people can afford a very expensive appliance.By: Sarah A.

Linksys Router Power Adapters
If you lost your Linksys router power adapter, there are a few options available to get your router back on working.
You can go to numerous electronic outlets, as well as exhaustive searches on the net, and don’t forget contacting Linksys directly. But first, you should see the manual to know the proper amount of voltage and current need by your router. Suppose its 12 volt DC 1 amp (12VDC 1 A). Then you can search for the one you need with this configuration. If you can’t find one, then you can search for 12 V 1000m amp as 1 amp is 1000 m amp (mill amperes). You can also have a universal plug connector. But you have to find the connector with matching rating and put it on the wire.

NVIDIA Graphics Cards
To run graphics intensive applications and play games, you need graphics cards that are capable of doing these things. These cards come in two ways, integrated in your motherboard and as extra add-in cards. Built-in motherboard graphics cards have very limited processing power compared to extra cards and they also share a considerable amount of RAM making it less than what you have. So, you need an extra graphics card that has enough processing capability and a memory of its own to do its job perfectly.
NVIDIA Graphics cards are one of two main types of graphics cards that are available today. These cards come with a wide number of GPUs with various range of processing power to cater to the needs of users of all levels. With a large amount of memory, these cards provide necessary power to run applications and games available today.
