Gbps (Gb/s, Gbit/s) is the speed with which information is transmitted. It is normally used to measure the speed information in the ADSL/fiber addresses transmitted.

• 1 Gb/s is equivalent to 1,000,000,000 b/s.
• 1 Gb/s is equivalent to 1000000 kb/s.
• 1Gb/s equals 1000 Mb/s.

A RAID consider an array of independent drives, but where all data is stored simultaneously on each disk independently, this means that in the case of any failure, the others continue to operate normally. A RAID typically consists of 2 or more hard drives. The RAID also has an important feature, since the discs can be balanced and avoid bottlenecks that are oftencause when there are problems.

ExpressCard is a hardware standard replacing the PCMCIA/PC Card/CardBus cards, both developed by the Personal Computer Memory Card International Association. The host device supports PCI-Express and USB 2.0 connectivity in the ExpressCard slot, and each card uses the mode of connectivity the designer considers more appropriate for the task. The cards can connect to the computer on without RESETiarlo (support Hot swap or hot plug). It is an open standard of the ITU-T and its definition can be obtained from the official website of ExpressCard. You can connect to this bus, different types of peripherals such as Wi-Fi cards, Bluetooth, TV cards, FireWire, etc.

A Peripheral Component Interconnect (PCI, "Peripheral Component Interconnect") is a bus (picture 2) computer standard for connecting peripheral devices directly to your motherboard. Dimensions of the cards - PCI (standard) 107 mm x 312 mm (picture 1) - PCI Low Profile Height: 36.07 mm x 64.41 mm Depth: 119.91 mm to 167.64 mm - Mini PCI Mini PCI cards have a Maximum consumption2W.

Serial ATA or SATA (acronym for Serial Advanced Technology Attachment) is a data transfer interface between the motherboard and some storage devices such as hard disk, regrabadores readers and CD/DVD/BR, SSDs or other high performance devices are still being developed. SATA I Frequency: 1500 MHz Bits: 1. Bits 8 Real Speed: 150 MB/s. SATA II. Frequency: 3000 MHz Bits: 1 bits 8 Real Speed: 300 MB/s. SATA III Frequency: 6000 MHz Bits: 1. Bits 8 Real Speed: 600 MB/s eSATA. SATA type connector for connection of external peripherals.
