SD (Secure Digital) card is about the size of a postage stamp and weights approximately two grams. SD card looks similar in size to a Multi Media Card but is smaller than older memory card types such as the Smart Media card and the Compact Flash card. SD cards are available with storage capacities as high as 4 gigabytes. The SD card was jointly developed by Matsushita, SanDisk, and Toshiba. The SD technology is used by more than 400 brands across dozens of product categories and more than 8,000 models, and is considered the de-facto industry standard. SD cards are more rugged than traditional storage medias. SD adapters allow the physical conversion of smaller SD cards to work in a larger physical slot, and basically are passive devices that connect the pins from the smaller SD card to the pins of the larger SD adapter.

 

WiFi, Wireless-N USB Adapter

Every one is cutting the wires. You see this with how we have WiFi every where. It is in our laptop computers, desktop computers and especially in our cell phones or internet phones. You see less voice calling and more online tasks being completed using wireless internet (WiFi) connections.

In many cases our desktop computers or laptops with standard PCI or Mini PCI wireless cards do not provide a stable connection for the reason of low wireless reception. To increase the reception we use external antennas.

But we have an other option which is more versatile,  that is having a Wireless USB Adapter in ones gadget kit.  In short, by using an USB wireless adapter, you can have around 60% better performance over the built-in WiFi that you find in laptops and desktops.

Secure Digital Card or SD card

Secure Digital card or SD card is a flash memory card that provides storage for portable various electronic devices like eBooks, digital cameras, PDAs, audio players, video recorders and mobile phones music players, camcorders and personal computers. SD cards are small in size, weighs approximately two grams and robust and have higher data transfer rates and low power consumption of primary energy, and mobile devices. It uses flash memory to provide non-volatile storage, which means that power is not necessary to retain stored data.
Secure Digital card is the size of postage stamp  It 'the same size as the MMC, but smaller than previous memory card types including Smart Media cards elderly and Compact Flash cards. Both MMC and SD cards can be encryption capabilities for protected content to ensure the secure distribution of copyrighted material, such as digital music, videos and books. SD cards are available with storage capacities up to 4 gigabytes.
Both MMC and SD card use metal connector contacts instead of the traditional pins and connectors, are therefore not subject to damage during handling

SD Card

Secure Digital (SD) is a flash (non-volatile) memory card format developed by Matsushita, SanDisk and Toshiba for use in portable devices, including digital cameras, handheld computers, PDAs and GPS units. As of 2007, SD card capacities range from 8 MB to 16 GB. Several companies have announced SD cards with 32 GB.

Cards with 4-32 GB are considered high-capacity. The format has proven to be very popular. However, compatibility issues between older devices and the newer 4 GB and larger cards and the SDHC format have caused considerable confusion for consumers.
SD cards are based on the older MultiMediaCard (MMC) format, but have a number of differences: ?The SD card is asymmetrically shaped in order not to be inserted upside down, while an MMC would go in most of the way but not make contact if inverted. SD cards typically have higher data transfer rates, but this is always changing, particularly in light of recent improvements to the MMC standard. Devices with SD slots can use the thinner MMCs, but the standard SD cards will not fit into the thinner MMC slots. SD cards can be used in CompactFlash or PC card slots with an adapter. miniSD and microSD cards can be used directly in SD slots with a physical interface adapter.There are some SD cards with a USB connector for dual-purpose use, and there are card readers which allow SD cards to be accessed via many connectivity ports such as USB, FireWire, and the parallel printer port. SD cards can also be accessed via a floppy disk drive with a FlashPath adapter.
