USB PORTS
USB PORTS USB ports and devices come in three versions—1.0, 2.0, and 3.0. Version 1.0 supported speeds of 1.5Mbps and 12Mbps. Version 2.0 increased the supported speed to 480Mbps; and Version 3.0 supports speeds up to 5Gbps.
SOUND CARD PORT
SOUND CARD PORT A sound card converts digital computer signals to sound and sound to digital computer signals. A sound card is sometimes called an audio card and can be integrated into the motherboard or an adapter that contains several ports. The most common ports include a port for a microphone, one or more ports for speakers, and an input port for a joystick or MIDI (musical instrument digital interface) device.
NETWORK PORTS
NETWORK PORTS
Network ports are used to connect a computer to other computers, including a network server. Ethernet adapters are the most common type of NIC (network interface card/controller). They can have a BNC, an RJ-45, a 15-pin female D-shell connector, or a combination of these on the same adapter. The BNC connector attaches to thin coax cable. The 15-pin D-shell connector connects to thick coax cable. The RJ-45 connector connects to UTP (unshielded twisted-pair) cable and is the most common Ethernet port used.
