true.
Universal Serial Bus
it contains a small amount of memory, or RAM, enough to configuration or setup information about the computer. This chip is responsible for remembering the current date and time, which hard drives and floppy drives are present, how the serial and parallel are configured and so forth. When the computer is first turned on, it looks to this CMOS chip to find out what hardware it should expect to find.
one bit at a time vs. a group of several bits at a time.
Universal Serial Bus [USB]
well it depends on the communication between computers. may be its electrical,optic or wireless. In electrical its may be in serial or parallel or encoded or decoded by TCP/IP method based on Ethernet medium. in optics its same phenomena but at end its converted light form and that data travels in fiber. and in wireless the mostly based on RF wave. :P
Serial and parallel.
Neither. A computer case is just a box to hold the parts of a computer. It provides no form of communication itself.
no,they connect devices via a serial pattern
Most serial adapters can be found on computers and they connect the monitor/screen to the actual computer itself. A serial adapter may also be used to connect your television to your laptop. In this case, you would connect the usb part to your television port where it is marked USB and the serial adapter part to your computer.
The RS 232 interface is one of the standards used in serial communications. It uses serial signals (as opposed to parallel) to connect computers to devices like printers and modems.
Well, the USB (universal serial bus) is a type of bus, but everything doesn't connect with one.There is also serial ports, sound jacks, and all that other fun stuff.
Serial port is by far the fastest port. It is so fast that it is used in modern computer to connect hard drive to motherboard. Current generation of serial port is SATA 6Gpbs.
The PS/2 ports connect a mouse and keyboard, while the game port connects game controllers. Parallel and serial ports connect older printers and PDA devices. Most current input devices use the USB port, of which there are usually several available on a modern computer. Firewire ports connect high-speed devices, including DV cameras and Firewire hard drives. Another high-speed hard drive connector is the eSATA port.
A SCSI (Small Computer System Interface) cable is a type of data cable used to connect various peripheral devices, such as hard drives, scanners, and printers, to a computer. It facilitates communication between the computer and these devices, allowing for data transfer and command execution. SCSI cables can support multiple devices on a single connection and come in various forms, including parallel and serial types. Although less common today, SCSI was widely used in older computer systems for high-speed data transfer.
One of the major advantages of USB over Serial/Parallel ports is the increase of speed between the device and your computer. Also, USB devices can be chained together so one USB port can be used by many devices. Lastly, USB is considered "hot swappable" - therefore your computer can easily disconnect one device and discover a new one that you have plugged in.
A "serial to parallel" converter converts a serial data connection to a parallel data connection. For example, in computer storage, there are controller chipsets that convert SATA (Serial ATA) to PATA (Parallel ATA, also called IDE or EIDE).
Parallel port devices are those devices which are connected to the computer via parallel ports. An example is Printer which is connected to the parallel port LPTx (Line Printer Terminal) eg: LPT1, LPT2, LPT3. Parallel ports were originally developed by IBM as a way to connect a printer to your PC. When a PC sends data to a printer or other device using a parallel port, it sends 8 bits of data (1 byte) at a time. These 8 bits are transmitted parallel to each other, as opposed to the same eight bits being transmitted serially (all in a single row) through a serial port. The standard parallel port is capable of sending 50 to 100 kilobytes of data per second.Answer-- A parallel port is a type of interface found on computers (personal and otherwise) for connecting various peripherals. It is also known as a printer port or Centronics port. The IEEE 1284 standard defines the bi-directional version of the port.
