The 6-conductor and 4-conductor alpha FireWire 400 socket A 9-pin FireWire 800 connector The alternative Ethernet-style cabling used by 1394c 4-conductor (left) and 6-conductor (right) FireWire 400 alpha connectors A PCI expansion card that contains four FireWire 400 connectors. FireWire is Apple's name for the IEEE 1394 High Speed Serial Bus.
Examples of computer connector sockets on various laptops Ports on the back of the Apple Mac Mini (2005) A computer port is a hardware piece on a computer where an electrical connector can be plugged to link the device to external devices, such as another computer, a peripheral device or network equipment. [1] This is a non-standard term.
In computer networking, a firewall pinhole is a port that is not protected by a firewall to allow a particular application to gain access to a service on a host in the network protected by the firewall. [1] [2] Leaving ports open in firewall configurations exposes the protected system to potentially malicious abuse.
ExpressCards can connect a variety of devices to a computer including mobile broadband modems (sometimes called connect cards), IEEE 1394 (FireWire) connectors, USB connectors, Ethernet network ports, Serial ATA storage devices, solid-state drives, external enclosures for desktop-size PCI Express graphics cards and other peripheral devices ...
Windows Firewall settings in Windows XP Service Pack 2.. Windows Firewall was first introduced as part of Windows XP Service Pack 2. Every type of network connection, whether it is wired, wireless, VPN, or even FireWire, has the firewall enabled by default, with some built-in exceptions to allow connections from machines on the local network.
An IEEE 1284 36-pin female on a circuit board. In the 1970s, Centronics developed the now-familiar printer parallel port that soon became a de facto standard.Centronics had introduced the first successful low-cost seven-wire print head [citation needed], which used a series of solenoids to pull the individual metal pins to strike a ribbon and the paper.
Some other computer architectures use different modules with a different bus width. In a single-channel configuration, only one module at a time can transfer information to the CPU. In multi-channel configurations, multiple modules can transfer information to the CPU at the same time, in parallel.
SCSI-1 card with an external Centronics port which requires a terminator, from an Acorn computer. Old Macintosh DB-25 SCSI port (narrow) Apple used DB-25 connectors, which, having only 25 pins rather than 50, were smaller and less expensive to make, but decreased signal integrity (increasing crosstalk ) [ citation needed ] and cannot be used ...
