|
|
|
What are Audio Ports?
|
are electrical connectors for carrying audio signalsof either analog or digital format. Analog A/V connectors often use Shielded cable to inhibit radio frequency interference (RFI) and noise.
|
|
|
What is Bluetooth?
|
wireless technology enables communication between Bluetooth-compatible devices. It is used for short-range connections between desktop and laptop computers, PDAs (like the Palm Pilot or Handspring Visor), digital cameras, scanners, cellular phones, and printers.
|
|
|
What is a Cache?
|
- Pronounced like "cash" A cache stores recently-used information in a place where it can be accessed extremely fast. For example, a Web browser like Internet Explorer uses a cache to store the pages, images, and URLs of recently visted Web sites on your hard drive
|
|
|
What is DIMM?
|
"Dual In-Line Memory Module." It is a type of computer memory. A DIMM is a small circuit board that holds memory chips.
|
|
|
What is DRAM?
|
"Dynamic Random Access Memory." DRAM is a type of RAM that stores each bit of data on a separate capacitor. This is an efficient way to store data in memory, because it requires less physical space.
|
|
|
What is EEPROM?
|
Electrically Erasable Programmable Read-Only Memory and is a type of non-volatile memory used in computers and other electronic devices to store small amounts of data that must be saved when power is removed, e.g., calibration tables or device configuration.
|
|
|
What is EPROM?
|
Erasable Programmable ROM) A rewritable memory chip that holds its content without power..
|
|
|
What is Ethernet?
|
Ethernet is the most common type of connection computers use in a local area network (LAN). An Ethernet port looks much like a regular phone jack, but it is slightly wider. This port can be used to connect your computer to another computer, a local network, or an external DSL or cable modem.
|
|
|
What is Fire Wire?
|
- This high-speed interface can be used to connect devices such as digital video cameras, hard drives, audio interfaces, and MP3 players, such as the Apple iPod, to your computer. A standard Firewire connection can transfer data at 400 Mbps ( Megabits Per Second), which is roughly 30 times faster than a USB.
|
|
|
What is a Hard Drive?
|
- Hard drive is what stores all your data. It houses the hard disk, where all your files and folders are physically located.
|
|
|
What is IEC?
|
the common name for a main electricity cable.
|
|
|
What is IRDA?
|
IrDA interfaces are used in medical instrumentation, test and measurement equipment, palmtop computers, mobile phones, and laptop computers (most laptops and phones also offer Bluetooth but it is now becoming more common for Bluetooth to simply replace IrDA in new versions of products).
|
|
|
What is Memory?
|
A byte is a set of 8 bits that represent a single character in the computer's memory.
|
|
|
What is MIDI?
|
pronounced /ˈmɪdi/) is an industry-standard protocol defined in 1982[1] that enables electronic musical instruments such as keyboard controllers, computers, and other electronic equipment to communicate, control, and synchronize with each other. MIDI allows computers, synthesizers, MIDI controllers, sound cards, samplers and drum machines to control one another, and to exchange system data.
|
|
|
What is Parallel?
|
- A parallel port is a type of interface found on computers (personal and otherwise) for connecting various peripherals. In computing, a parallel port is a parallel communication physical interface. It is also known as a printer port.
|
|
|
What are Ports?
|
'port' serves as an interface between the computer and other computers or peripheral devices.
|
|
|
What is PROM?
|
"Programmable Read-Only Memory," . Standard PROM can only be programmed once. This is because PROM chips are manufactured with a series of fuses. The chip is programmed by burning fuses, which is an irreversible process. The open fuses are read as ones, while the burned fuses are read as zeros.
