chip on board

  The term Chip on Board (COB) which is sometimes referred to as System in Package (SIP) refers to the semiconductor assembly technology wherein the microchip or die is directly mounted on and electrically interconnected to its final circuit board, instead of undergoing traditional assembly or packaging as an individual IC. The elimination of conventional device packaging from COB assemblies simplifies the over-all process of designing and manufacturing the final product, as well as improves its performance as a result of the shorter interconnection paths.


SD High Capacity (SDHC™) card is the new SD™ memory card based on the SDA 2.00 specification, introduced by the SD Card Association. This new SDA 2.00 specification enables SD cards to reach higher capacities - 4GB-32GB*. 

Because SDHC works differently than standard SD cards, this new format is not backwards compatible with legacy SD format host devices. 4GB* SDHC cards can only work with SDHC compatible host devices, such as digital cameras and camcorders. To ensure compatibility, look for the SDHC logo on cards and host devices. 

What is Class Speed Rating?
The SD Association has created and defined 3 speed classes to help you identify speed and performance capabilities/minimum requirements of SD/SDHC cards and the host products. The SD Speed Class Ratings specify a minimum sustained write speed for SDHC cards. 

The Speed Classes are:
Class 2 - 2MB*/second
Class 4 - 4MB*/second
Class 6 - 6MB*/second 
    Look for these logos to identify
your class rating:


*Please note: For Flash Media Devices, 1 megabyte = 1 million bytes; 1 gigabyte = 1 billion bytes. Actual usable capacity may vary. Some of the listed capacity is used for formatting and other functions, and thus is not available for data storage.


Windows® ReadyBoost™ improves system responsiveness and boosts performance. Windows® Vista™ introduces Windows® ReadyBoost™, a new concept in adding memory to a system. You can use non-volatile flash memory, such as that on a universal serial bus (USB) flash drive, to improve performance without having to add additional system memory "under the hood”.


Encryption is the conversion of data into a form, called a ciphertext, that cannot be easily understood by unauthorized people. Basically is it protection for your data.


A revolutionary approach to scalability—combining multiple graphics cards in a PC to scale performance—NVIDIA® SLI™ technology takes advantage of the increased bandwidth of the PCI Express™ bus architecture, and features intelligent hardware and software solutions that allow multiple NVIDIA GPUs to efficiently work together to deliver earth-shattering performance.


Hybrid SLI technology, based on NVIDIA's industry-leading SLI technology, delivers multi-GPU benefits when a NVIDIA motherboard GPU is combined with a NVIDIA discrete GPU.


The Enthusiast System Architecture (ESA) is the industry’s first open-standard PC monitoring and control protocol for real-time communication and control of system thermal, electrical, acoustic and operating characteristics.

NVIDIA PureVideo

NVIDIA PureVideo™ technology is a combination of the GeForce 6, 7 and 8 Series GPUs’ high-definition video processor and NVIDIA video decode software that delivers unprecedented picture clarity, smooth video, accurate color, and precise image scaling for all video content on any display.

PCI Express

PCI Express is a new Intel PC bus architecture that doubles the bandwidth of the AGP 8X bus, delivering over 4GB per second in both upstream and downstream data transfers. The graphics processing unit (GPU) has the largest bandwidth appetite of all PC subsystems, and from the start NVIDIA has been a key contributor to the PCI Express architecture, as a developer, a supporter, and as a provider of PCI Express graphics solutions.

Windows Vista

Continuing its commitment to develop innovative products that enhance the end-user experience, NVIDIA has been working with Microsoft in preparation for the highly anticipated, next-generation Windows® operating system (OS)-Windows Vista™ (formerly Windows code name "Longhorn").

Extreme HD

Go beyond standard high definition (HD) and experience Extreme High Definition (XHD), the ultimate widescreen, ultra-high-resolution PC experience made possible by NVIDIA® GeForce® graphics processing units (GPUs). XHD has over 4x the picture clarity of native 1080i HD televisions and 2x the picture clarity of 1080p HD televisions on today’s hottest PC games.


Bluetooth is a specification for the use of low-power radio communications to wirelessly link phones, computers and other network devices over short distances. The name "Bluetooth" is borrowed from Harald Bluetooth, who was a king in Denmark more than 1,000 years ago. 

Bluetooth technology was designed primarily to support simple wireless networking of personal consumer devices and peripherals, including cell phones, PDAs, and wireless headsets. The wireless signals transmitted in Bluetooth reach over short distances, typically up to 30 feet (10 meters). Bluetooth devices generally communicate at less than 1 Mbps.


GSM phones require a small electronic chip, called a SIM card, to be inserted into a slot in the handset. This international SIM card is the "heart" of your phone - it contains your cell phone number, your phone book, and all of your registration information. Most companies with GSM service provide you access to over 320 GSM networks in over 140 countries. 

What are Unlocked GSM Phones?
Unlocked GSM phones are either (a) phones which are directly from the manufacturer which were locked, or (b) phones from a carrier which have been modified to openly work on any network.


Serial ATA (Serial Advanced Technology Attachment or SATA) is a new standard for connecting hard drives into computer systems. As its name implies, SATA is based on serial signaling technology, unlike current IDE (Integrated Drive Electronics) hard drives that use parallel signaling. 

SATA has several practical advantages over the parallel signaling (also called Parallel ATA or PATA) that has been used in hard drives since the 1980s. SATA cables are more flexible, thinner, and less massive than the ribbon cables required for conventional PATA hard drives. SATA cables can be considerably longer than PATA ribbon cables, allowing the designer more latitude in the physical layout of a system. Because there are fewer conductors (only 7 in SATA as compared with 40 in PATA), crosstalk and electromagnetic interference (EMI) are less likely to be troublesome. The signal voltage is much lower as well (250 mV for SATA as compared with 5 V for PATA).


NVIDIA CUDA is a programming platform. CUDA enabled products can help accelerate the most demanding tasks—from gaming , to video and audio encoding to oil and gas exploration, product design, medical imaging, and scientific research.
