PORTS & PC COMPONENTS
b: provided on many video cards, computer monitors, laptop computers, projectors, and high definition television sets.
c:On laptop computers or other small devices, a mini-VGA port was sometimes used in place of the full-sized VGA connector.
-
b:data was transferred through serial ports to devices such as modems, terminals, and various peripherals.
c:such interfaces as Ethernet, FireWire, and USB all send data as a serial stream, the term "serial port" usually identifies hardware more or less compliant to the RS-232 standard, intended to interface with a modem or with a similar communication device.
-
b: send multiple bits of data at once, in parallel communication, as opposed to serial interfaces that send bits one at a time
-
a:an industry standard that establishes specifications for cables, connectors and protocols for connection, communication, and power supply between personal computers and their peripheral devices
b:designed to standardize the connection of peripherals like keyboards, pointing devices, digital still and video cameras, printers, portable media players, disk drives and network adapters
a:an interface standard for a serial bus for high-speed communications and synchronous real-time data transfer
-
c: Power is also carried over this cable, allowing devices with moderate power requirements to operate without a separate power supply.
b:a family of computer networking technologies commonly used in (LAN), (MAN) and (WAN).
-
a: the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output
b:the term "CPU" refers to a processor,
c:Most modern CPUs are microprocessors, meaning they are contained on a single integrated circuit (IC) chip
b: Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially.
-
a:an electromechanical data storage device that uses magnetic storage to store and retrieve digital information
