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.
