Graphics cards with bigger RAMs perform better. This theory is not true. RAMs are employed on the graphics cards to store data and allow for features that are needed to run games. More RAM doesn't always make a difference because the amount of RAM doesn’t have a direct influence on graphics cards performance. But bandwidth of the RAM has.
Clock rate and interface width are the two factors that affect bandwidth of a graphics card RAM. Clock rate is measured in MHz whereas width of an interface is measured in bits. Greater bandwidth means more data transfer at a time which increases the performance. 200 MHz memory transfers data faster than 100 MHz memory and 256 or 128 bit interface is always quicker than 64 bit interface.

Computer System Upgrades
Upgrades mean to change or replace an older version of any kind of hardware, software or program with a newer version. This term is generally used for computer systems and other consumer electronics. In the case of computers, upgrades include RAM replacement or addition, adding multiple hard drives, processor upgrade, graphics cards, sound cards, replacing the existing CRT monitor with an LCD or LED, installing high-performance software and other applications, etc.
However, you should keep in mind that not all the upgrades work swiftly with the existing system. So, it is recommended that don’t purchase any upgrades without trial and authentication. You should upgrade your system with the high-quality products from various renowned brands like SONICWALL, Compaq, IBM, etc.

EDO Memory
EDO Memory, the short form of Extended Data-Out memory is a memory chip technology that helps in improving the memory performance up to 10-15 percent if attached to an equivalent and compatible device.The DRAM is structured based on the matrix bits and thus; due to time restriction, the capability of higher performance is limited by the memory controller. On the other hand, an EDO memory permits the controller to start a new column address when performing at the present address. So, the total operating performance increases significantly.
Generally, the exterior of an EDO memory is similar to a SIMM memory, but the designs of the chips are different.
Use of DIMM memory modules in computers
DIMM means Dual In Memory Module. DIMM chips are DRAM chips connected in series. They are used widely in personal computers. DIMM chips have a printed circuit board which connects the different DRAM chips in series so that they can be used in a computer.
DIMM memory modules have a 64 bit memory path and they began to get popular with Intel based P5 systems. There are different types of DIMM cards according to the number of pins on each card. DDR DIMMs are popular in present day computing technology with DDR3 DIMM in the top. DDR2 and DDR3 each have a different notch positions in their DIMM cards to prevent accidental entry of one card in to a slot allotted for other type of card.
Most of the DIMM memory modules are built with x4 or x8 DRAM memory chips with 9 memory chips per side. The speeds increase as the type of DRAM in DIMM chips differs. DDR3 stands at the top in speed with DDR2, DDR and SDRAM DIMM in order.

PCBA Printed Circuit Board Assembly
The PCBA stands for Printed Circuit Board Assembly. As we all know that computer system works with the integration and combination of various components so, it is necessary to connect all the required components and devices via printed circuit board and there lies the significance of PCBA.
It is used to connect the electronically attached components by means of mechanical support. The PCBA consists of different pathways with internal copper wiring, and a laminate, which is electrically neutral or non-conductive.
The main advantage of a PCBA is, it is reliable and can be designed according to the desired size and shape. However, the initial cost is a bit higher, but they are very much affordable and faster for bulk production and distribution. Moreover, the production and joining of PCBA can be done by automated equipments without any hassle.

Sound Cards
Whenever we listen to music and watch movies on our computer, it gives us lots of pleasure. This great opportunity is provided by a computer chip known as sound card. Sound cards are internal computer expansion cards that are provided with both input and output audio signals facilities from and to the computer by means of some computer programs.
The general use of sound cards includes multimedia applications such as video editing, music composition, watching videos, presentations, educations, etc. It is also used to hear the notification alert of the computer system while running different programs.
The reputed brands of sound cards include Creative, IBM, Dell, Compaq, Ncr, Gateway, NEC and many more. If you want to hear the surround sound to your music and movies, you can purchase a 5.1 or 7.1 sound card to fulfill your demand quite easily.

SDRAM and its significance
SDRAM stands for Synchronous dynamic random access memory. SDRAM devices are synchronised to system bus and it waits to sync with system bus before responding to the input controls. This enables SDRAM to function at higher speeds than DRAM. SDRAM cards are widely used in computers.
DDR, DDR2 and DDR3 are generations of memory modules than have been developed from SDRAM. SDRAM has auto refresh feature which allows refresh the data without physically removing the device from the computer. SDRAM also has a low power mode. SDRAM is relatively a slower version than DDR as the SDRAM chip only transmits single word of data per clock cycle.
The initial SDRAM was also called Single Data Rate SDRAM also known as SDR SDRAM. A double data interface was developed for SDRAM modules which enable to transfer two data words in a single clock cycle so that the device can perform with high speed transfers. This was named as DDR SDRAM.

PC Card-What Are They Used For?
A PC Card is identified as the structure-aspect of a secondary interface usually meant for notebook computers. The PC card was known as PCMCIA card earlier.The size of a pc card is similar to the size of a credit card. This type of card was primarily used as the storage device. However, later with the advancement of technology and further applicability for notebooks, this car is used as the communication modems for the laptop and notebook computers.
The PC Card is available in 16 bit and 32 bit mode. Depending upon the thickness and types of this card, other uses of it includes, ATA drives, memory, LAN, sound, SCSIs, etc.
