3D sound card

the time it takes a storage device to locate its stored data
the number of bits a video card uses to store data about each pixel on the monitor
a type of high-speed memory that a processor can access more rapidly than main memory
In a CPU, the speed at which it can potentially execute instructions, measured in millions of cycles per second—megahertz (MHz)—or billions of cycles per second—gigahertz (GHz). (1)
a complete processing section from a CPU embedded into one physical chip
measurements used to compare performance between processors
the percentage of time that your CPU is working
CPU usage graph
records your COY usage for the past several seconds
The latest PCMCIA standard for notebook I/O cards that uses the PCI Express and USB 2.0 data transfer standards. Two types of Express-Cards are ExpressCard/34 (34mm wide) and ExpressCard/54 (54mm wide).
external SATA (eSATA)
A standard for external drives based on SATA that uses a special external shielded SATA cable up to 2 meters long. eSATA is up to six times faster than USB or FireWire.
front side bus (FSB)
connects the processor (CPU) in your computer to the system memory. Think of it as a highway on which data tavels between the CPU and RAM.
graphics double data rate 5 (GDDR5)
a standard of video memory
computer hardware that holds and spins a magnetic or optical disk and reads and writes information on it
(computer science) a crash of a read/write head in a hard disk drive (usually caused by contact of the head with the surface of the magnetic disk)
A technology that permits quicker processing of information by enabling a new set of instructions to start executing before the previous set has finished.
the memory that the computer's operating system uses.
latency (rotational delay)
the process that occurs after the read/write head of the hard drive locates the correct track, and then waits for the correct sector to spin to the read/write head
memory module (memory card)
a small circuit board that holds a series of random access memory (RAM) chips
The premise that the power of microprocessor technology doubles and its cost of production drops in half every 18 months
computer storage that is not lost when the power is turned off
A type of media used to store data which is read by a laser, such as a CD or DVD.
the amount of RAM that is actually sitting on memory modules in your computer
a thin, round, metallics storage plate stacked onto the hard drive spindle
Random Access Memory (RAM)
Temporary memory a computer uses to store information while it is processing.
A sealed, magnetic coil device that moves across the surface of a disk either reading data from or writing data to the disk.
redundant array of independent disks (RAID)
Two or more disks combined into one large drive in several configurations for special needs. Some RAID systems are designed for redundancy to ensure continuous operations if one disk fails. Another configuration spreads data across several disks to improve access speeds for reads and writes.
A section of a hard drive platter, wedge-shaped from the center of the platter of the edge
(computer science) the time it takes for a read/write head to move to a specific data track
Serial Advanced Technology Attachment (SATA)
a type of hard drive that uses much thinner cables, and can transfer data more quickly, than IDE drives.
Solid-State drive (SSD)
a drive that uses the same kind of memory that flash drives use, but can reach data in only a tenth of the time a flash drive requires
an expansion board that enables a computer to manipulate and output sounds
a memory-management technique used by windows 7. monitors the applications you use the most and preloads them into your system memory so that they'll be ready to go
a type of audio processing that makes the listener experience sound as if it were coming from all directions
the process of looking at a computer's subsystems, what they do, and how they perform to determine whether the computer system has the right hardware components to do what the user ultimately wants it to do
a concentric circle that serves as a storage area on a hard drive platter
video card (video adapter)
An expansion card that is installed inside a system unit to translate binary data (the 1s and 0s the computer uses) into the images viewed on the monitor.
RAM that is included as part of a video card
computer storage that is erased when the power is turned off
