It was invented by an israeli company called "M-Systems" and the brand is called "Disk on key" If you are wondering about USB the Technology: USB was first released in 1995 by a number of companies including Copmaq, DEC, Microsoft, Intel, NEC and Nortel. If you are wondering about USB flas…h drives: Many companies claim to have invented the USB storage device bit M-Systems was the one to get the patent in 2000. Trek Technology and IBM began selling the first USB flash drives commercially in 2000. All Wrong... the M-systems comment is likely talking about the USB Flash Drive commonly known as the USB Thumb Drive. From my research the Universal Serial Bus USB was known about as early as 1994. The only fact about this is that a number of companies teamed up in its creation, Microsoft, Intel, etc. It was officially released January 1996 and put into production February 1996. USB 1.0 was likely invented sometime in 1995. ( Full Answer )
A serial port is any port that transmits and receives data serially , or one piece at a time. This is as opposed to a parallel port, which can transmit and receive data along multiple paths at the same time. RS-232, USB, FireWire, PS/2, and ADB are all examples of serial ports. In common usage, the… term "serial port" is usually used to refer to RS-232 ports. ( Full Answer )

Many computers do not include a serial port these days, and no modern peripherals use it. If you do not know if you need one or not, you most likely don't.
The serial port is mostly used to connect Modems. However, there are many devices that can connect to the serial port. Some of these are, mouses, trackballs, scanners, Ham radio equipment, cash registers and many many more.
A standard/typical serial port features 25 pins (d-sub) or 9 pins.However, some special serial ports like USB and PS/2, areconfigured differently.
A serial port is a side socket in which electrical current can beconnected. A bus is a electrical device allowing connection and thetransfer of information.
serial and parallel are legacy network ports, from way back when before eathernet and usb were adopted as standard. they were both used extensively for printer interfaces, but have since been superseded by usb. in the pre-usb days, specialist hardware such as detectors or motor controls would connec…t to the parallel port, and if two computers required direct networking they would be connected on serial.

Many older laptops (2005 and prior( include at least one serialport. It is not specific to any particular model or brand; theywere at one time ubiquitous. The last model that dell made was the D830 latitude. It had serialport built in. we bought some from laptopoutlet.com.
Based on the definitions at the associated links, a bus is an electronic connection which allows the transfer of information, whereas a port is a socket in the side of a computer which allows a matching plug to connect to that computer.
The universal serial bus (USB) is a communication device, however it can communicate just about anything that the computer knows about. There are currently available many USB devices available to which the computer can send digital data for storage, including but not limited to: . USB memory sti…cks . USB disk drive adapters which convert the signals to/from an external disk drive to simple communication signals. . USB communication to cameras, then the computer just treats the camera as another disk drive. . USB audio devices. Songs are stored as digital files on the device. . But USB devices are not limited to storage ( Full Answer )
A serial port is a type of port which sends and receives data one bit at a time, as opposed to parallel ports which can send and receive in multiple streams. A COM port is a type of serial port.

You need to purchase an adapter for this conversion. Just google and you will find many on the net.
USB ( Universal Serial Bus) serves both purposes...both output and input....when we copy something into a pen drive it serves as an output and when we view something from a pen drive it serves as an Input.
In serial bus, if there are multiple masters, then multiple master decides whether it acquires the bus or not using data pattern. In case where master needs to drive 0, it would drive other wise it would release. Master would always figure out whehter it has acquired the bus or not by checking the b…us being equal to 1 when it is not driving. If it is driven as 0, then it would understand that it is occupied by other master. So it would release the bus. ( Full Answer )

A bus is just a collection of wires or a means to carry data. The term came from the old days when the main board only had traces and sockets, and no real components. The backplane resembled the "bus bars" in a telephone system. Now, a bus is generally traces on a motherboard or a type of interface.… Serial here refers to data being sent end-wise, one bit at a time. If it were parallel, at least one byte would be sent at a time. ( Full Answer )

USB stands for Universal Serial Bus. USB's purpose is to provide a Universal method of transferring information to and from the computer. USB supports a variety of input and output devices: printers, keyboards, mice, portable hard drives, flash drives, scanners, music players, GPS, WiFi adapte…rs, barcode scanners, credit card swipers, just to name some. The protocol is universal, as well as the 'plug' into the computer. Previous input/output methods were specialized to the type of device: parallel for printers, special ports for keyboards, mice, serial ports for modems and mice and other serial devices, SCSI for scanners & external hard drives. Macs and PC's had different types of adapters and protocols and were not compatible with each other. There are different speeds. 1, 2, 3. Nearly all computers have USB Speed 2. New ones have USB 3.

A serial port is a 9 pin, RS-232 connection usually used for Terminal connections and older modems as well as some mice and older keyboards for example. It has lost much of it's popularity and is uncommon on modern computers, usually must be emulated via USB or another port. Usually it's low spee…d with a asynchronous connection. A parallel port is usually a 25 pin connection used primarily for printers, some times external devices such as Hard drives or CD-ROM drives, even scanners and modems. It is able to send more then one bit at a time. It is also becoming more obsolete and is less and less common on modern computers. Hope that helps. ( Full Answer )

USB is an abbreviation of Universal Serial Bus. In other words, we don't call USB the universal serial bus, we call the universal serial bus USB. As to why it's actually called the universal serial bus in the first place, prior to the USB interface, computer hardware devices were limited to using t…he standard serial port (RS-232) or parallel port (IEEE 1284). Other interfaces, such as SCSI, were also available, but manufacturer's quite often provided proprietary interfaces via peripheral expansion cards. This was usually because the existing standard interfaces were too slow. The upshot was that every time you bought a new device you had to be sure you had an interface available for it, or at least a spare expansion slot that could accommodate a new interface. If you had more than one device sharing the same interface, you often had to unplug one in order to use the other. Hot-swapping was rarely an option so this often meant you also had to reboot the system. The ability to daisy-chain devices together on a single port also wasn't always possible as most devices didn't provide a secondary port. Even those that did provide secondary ports weren't guaranteed to work well with the existing hardware. And if you decided to upgrade your computer, you had to be sure it had all the required interfaces for your existing peripheral devices. And certain combinations of hardware became impossible because expansion options weren't always possible. Thus the industry decided to come up with a new standardised interface that all manufacturers could comply with, and that allowed interconnectivity between those devices via a single port. Thus USB, the universal serial bus, was born. The name is somewhat conceited as it's really just a global serial bus, however the universal nature is limited to the universe of computer hardware devices, not The Universe itself! It should be noted that by the time USB was fully developed (in 1996), Apple had already developed it's proprietary FireWire standard (in 1995) which was intended to address the same problems as USB. FireWire was standardised as IEEE 1394 and can still be found on many non-Apple products today. However, the industry, as a whole, including Apple, has fully-embraced the USB standard. Proprietary interfaces are largely a thing of the past now that the industry works together to improve the USB interface without rendering older USB devices (legacy devices) completely obsolete. As well as providing two-way communication between interconnected devices, USB also provides low-voltage power to those devices. Large devices such as printers and scanners still require their own independent power supplies, but the low-voltage can provide enough power to allow connected devices to communicate with each other even when they are not fully-powered, while smaller devices, such as solid-state storage devices, can be powered via USB alone. Devices can also be hot-swapped. Some devices require complex driver software that may require a reboot to be fully-installed, however once the drivers are installed the device can be hot-swapped normally. Most computers provide at least one hub (with at least one port) that allows several devices to be connected at once (the low-voltage power is shared amongst all devices). Additional ports can be made available by adding more hubs, or by daisy-chaining hubs together. Each hub has its own independent power supply shared amongst all its ports. Many devices also provide their own hubs, thus allowing independent devices to be daisy-chained together. For instance, many computers have a USB printer attached, but the printer may provide its own USB hub for attaching a camera. The images on the camera can be transferred to the computer (perhaps even saved on another USB device, such as an external hard-drive) or they can be printed directly on the printer. USB interfaces are not the be-all-and-end-all to the interface problems we faced prior to USB. It is constantly being reviewed and improved so there will inevitably be some problems connecting newer USB devices to older USB interfaces. The standard is backwardly compatible, but this may still mean losing certain features within the new hardware -- most notably the speed of data transfers. However, the connection itself (the Type A plug) hasn't changed since it was originally developed. Not all devices support the Type A due to its large size, however adapters are available to switch between all the various USB standards, including Type B, Mini-A, Mini-B, Micro-A and Micro-B. While there are still some companies that continue to use proprietary interfaces, such as the 30-pin Apple iPhone connector, even they have seen the sense in providing adapter's to convert those interfaces to a compliant USB interface. Even devices that were never intended as USB devices can be converted to use a USB interface. For instance, hard-drives typically use a SCSI, SATA or IDE interface, but they can be converted to USB by installing them in a suitable USB housing. The housing includes all the hardware necessary to convert between the two interfaces. And although the hard-drives are typically capable of far higher data transfer rates via their intended interfaces, the added flexibility of hot-swapping these devices between computers is often the primary reason for converting them to USB in the first place.

A com port was originally intended for communications. Back during that time period, it referred to modems and crude networking. Serial means that the data is sent "end-wise" one bit at a time. That is opposed to parallel which means one or more entire bytes are sent at a time.
