Dvorak Keyboard Definition The Dvorak keyboard is a keyboard layout named after its designer, Dr. August Dvorak. He designed the keyboard as alternative to the standard QWERTY keyboard layout, with the goal of improving typing ergonomics. Dvorak developed the new keyboard layout after studying common typing patterns. He determined the QWERTY layout, which was designed for telegraph operators and early ..

Video Card Definition Most of the processing done on a computer is done via the computer’s central processing unit, or CPU. So in order to give the CPU a break and help it run more efficiently, a video card can be used to process the graphics portion of the processing load. Because most of today’s programs ..
PCB Definition Stands for “Printed Circuit Board.” A PCB is a thin board made of fiberglass, composite epoxy, or other laminate material. Conductive pathways are etched or “printed” onto board, connecting different components on the PCB, such as transistors, resistors, and integrated circuits. PCBs are used in both desktop and laptop computers. They serve as the ..
Motherboard Definition The motherboard is the main circuit board of your computer and is also known as the mainboard or logic board. If you ever open your computer, the biggest piece of silicon you see is the motherboard. Attached to the motherboard, you’ll find the CPU, ROM, memory RAM expansion slots, PCI slots, and USB ports. It also includes controllers for devices like the hard drive, ..
Hardware Definition Computer hardware refers to the physical parts of a computer and related devices. Internal hardware devices include motherboards, hard drives, and RAM. External hardware devices include monitors, keyboards, mice, printers, and scanners. The internal hardware parts of a computer are often referred to as components, while external hardware devices are usually called peripherals. Together, they all fall under the ..
DVR Definition Stands for “Digital Video Recorder.” A DVR is basically a VCR that uses a hard drive instead of video tapes. It can be used to record, save, and play back television programs.

Hm… Actually, a workstation is a place where work gets done. It refers to a computer (and often the surrounding area) that has been configured to perform ..
ECC Definition Stands for “Error Correction Code.” ECC is used to verify data transmissions by locating and correcting transmission errors. It is commonly used by RAM chips that include forward error correction (FEC), which ensures all the data being sent to and from the RAM is transmitted correctly. ECC RAM or memory is similar to parity RAM, which includes ..
DIMM Definition Stands for “Dual In-Line Memory Module.” It is a type of computer memory. A DIMM is a small circuit board that holds memory chips. It uses a 64-bit bus to the memory, whereas a single in-line memory module (SIMM) only has a 32-bit path. This allows DIMMs to transfer more data at once. ..
RAM Definition Stands for “Random Access Memory” and is pronounced “ram.” RAM is a common hardware component found in electronic devices, including desktop computers, laptops, tablets, and smartphones. In computers, RAM may be installed as memory modules, such as DIMMs or (SO-DIMMs sodimm). In tablets and smartphones, RAM is typically integrated into the device and cannot be removed. The amount of RAM in a ..
