...Edgar Pixtun NT1110 Ports and Connectors There are many ports and connectors to a computer. The ports are; Serial, Parallel, and Game Ports. A serial port transfers 1 bit of data at a time and is a male port that has 9 or 25 pins, where as a parallel port transfers 8 bits at a time and is a female port with 25 pins, and a game port is a female port as well that has 15 pins laid out in 2 rows. Most computers have now replaced these with USB ports. There are two different USB (Universal Serial Bus) ports. USB port 1, transfers 12 Mbps and is 3 meters wide. USB port 2, transfers 480Mbps and is 5 meters wide. USB connectors come in two sizes, A-connector, and a B-connector, which is the smaller connector. A mouse and keyboard both use a PS/2 port but are now using a USB port wireless. USB can have a limit of 127 devices plugged in at the same time. NIC (Network Interface Card) converts parallel communication to serial and uses an RJ-45 connector. A Modem connects to the phone line but is the slowest way to connect to the internet. It has a transfer speed of 56kbps but V.92 is quicker and it converts analog into digital. The Modem uses a RJ-11 connector. Computers come with two input/ output connections, VGA that has an analog interface that is a D-type connector that has 15 pins laid out in 3 rows, a DVI that is a digital visual interface, and a S-video that connects to the T.V. and that is round with 4 or 7 pins. An SCSI has 2 different connectors narrow and wide. The...

...What is a Motherboard? The Motherboard is the main circuit board inside the PC. It holds the CPU and memory, provides expansion slots for peripherals, and, whether directly or indirectly, connects to every part of the PC. The essential motherboard make-up includes the chipset (known as the “glue logic”), some code in ROM and the various wired interconnections between the components know as buses. The chipset is fundamental, and controls how the motherboard interacts with everything else in the system. A good chipset can be more important than the power of CPU or the amount of RAM. The ROM code includes the BIOS, which has user-changeable options for how the motherboard operates with integral and connected devices. The buses are the electrical wires that connect everything together. Motherboard designs use many different buses to link their various components. For instance, wide, high-speed buses are difficult and expensive to produce. The signals travel at such a rate that even distances of just a few centimetres cause timing problems, while the metal tracks on the circuit board act as miniature radio antennae, transmitting electromagnetic noise that introduces interference with signals elsewhere in the system. For these reasons, design engineers try to keep the fastest buses confined to the smallest area of the motherboard and use slower, more robust buses for other parts. Types of Slots on a Motherboard Motherboards are the backbone of a computer, holding different...

...For Task 1: Identify the Ports On my personal laptop, I have 4 USB connectors and a RS232 connector. There was a diagram given on the assignment where I need to identify the ports and adapters labeled in the diagram. I will start at the top left and work clockwise around the diagram to properly identify each one. The first one contains a SPDIF optical digital audio port and 5 1/8-inch mini-jack audio ports. Next we have USB ports then a USB micro socket. Next is the blue colored port which is called a serial port. The last one on the top is mini USB ports. Now continuing to go clockwise but moving to the bottom the PS/2 mouse and/or keyboard adaptor is located. The biggest connector is the parallel port and finally is the Ethernet port. For Task 2: Identify Memory Slots Task 3: Identify the Configuration The configuration shown is SCSI controller which stands for small computer systems interface which is generally used for mass storage. The need of a SCSI connector would be to hook up additional peripheral. A SCSI adaptor allow you to install multiple harddrives, disk drives, scanners, printers, and etc. through one port on your motherboard.

...A port expander is computer hardware that allows more than one device to connect to a single port on a computer. A port expander can be any device to which one existing or onboard port becomes two or more. There are two basic forms of port expander, internal and external. An internal expander has a connection inside the computer, typically on the motherboard, and the only part the user sees is the expansion plate containing multiple ports. An external device plugs into the existing port and then has multiple places to connect. When not part of a computer system, these devices are commonly known as splitters. Port expanders have several different types of ports available on the expander hardware. Below I have listed each type of port, picture of the port and its definition: * Ethernet is a family of computer networking technologies for local area networks. * IEEE 1394 interface is a serial bus interface standard for high-speed communications and isochronous real-time data transfer. * Parallel port is a type of interface found on computers for connecting peripherals. * PS/2 connector is a 6-pin Mini-DIN connector used for connecting some keyboards and mice to a PC compatible computer system. * Serial port is a serial communication physical interface through which information transfers in or out one bit at a time. * Universal Serial Bus (USB) is an industry standard developed in the mid-1990s that defines the cables, connectors and communications...

...Port connectors may be male or female, but female connectors are much more common. Bent pins are easier to replace on a cable than on a connector attached to a computer, so it was common to use female connectors for the fixed side of an interface. Computer ports in common use cover a wide variety of shapes such as round (PS/2, etc.), rectangular (FireWire, etc.), square (Telephone plug), trapezoidal (D-Sub — the old printer port was a DB-25), etc. There is some standardization to physical properties and function. For instance, most computers have a keyboard port (currently a Universal Serial Bus USB-like outlet referred to as USB Port), into which the keyboard is connected. Physically identical connectors may be used for widely different standards, especially on older personal computer systems, or systems not generally designed according to the current Microsoft Windows compatibility guides. For example, a female 9-pin D-subminiature connector on the original IBM PC could have been used for monochrome video, color analog video (in two incompatible standards), a joystick interface, or for a MIDI musical instrument digital control interface. The original IBM PC also had two identical 5 pin DIN connectors, one used for the keyboard, the second for a cassette recorder interface; the two were not interchangeable. The smaller mini-DIN connector has been variously used for the keyboard and two different kinds of mouse; older Macintosh family computers used the mini-DIN for a serial...

...what exactly is a port expander ,the author of this essay asks? A port expander is basically a device, that can be connected internal through the motherboard or an external connector, witch allows you to connect multiple devices to a single port. The way the port expanders works is it literally act as an add on for other devices. Think of a port expander like a modern surge protector. A surge protector has a single prong on the end of it to plug into one outlet but the surge protector also has several connector points on its other end to expands the one electrical unit to about several different units. This is the same idea for a port expander. The port expander has on connector port that goes into the receiving computer port and on the other end of that connector port are about several ports that can be used with the single connector port. Port expanders are very much so universal, simply because the ports themselves are universal so there aren't any specific expanders, or another that port expanders are called is a hub, for specific computers and they are generic devices that will work with any computer. So with ports there are some good reasons or advantages for them but just as there is good you also have the bad or disadvantages for them as well. One disadvantage or the major disadvantage would be because that one port is be shared with so many devices it will definitely cause slower connection speed between transmitting information between the ports. To offset that disadvantage...
