Generally, no; modern computers have several USB (Universal Serial Bus) ports rather than the RS-232 serial ports, Centronics parallel (printer) ports, joystick/game ports or PS2 ports of older machines.
In addition, newer machines may have FireWire ports or eSATA ports. The newest computers will usually have USB3 ports rather than the older USB2; USB3 is several times faster than USB2.
What else can I help you with?
How could you recognize parallel and serial port of computer?
Parallel ports typically have 25 or 36 pin ports. Serial ports, by contrast, have only 9 pins. Both type of ports have two rows of pins.
Is a USB port and COM1 the same thing?
No. Both COM ports and USB ports are serial interfaces, but the COM interfaces are driven by single device UARTs.
What type of connector is typically used for the RS-232 Serial Ports on PCs?
Serial ports typically use a DE-9 (sometimes mistakenly called "DB-9") connector. This is a connector with 9 male pins protruding from the computer. They are part of a group of connectors called "D-sub" connectors, both because of their shape, resembling a "D", and their size which was rather small at the time they were introduced.
When would you disable the serial port?
In the past, both the serial and parallel port were the most common means of data transfer and communication used by PCs. Serial ports were used for devices such as modems, mice, and serial port printers. However, in newer PCs, both the serial and parallel ports have been replaced by the use of USB ports. You should only disable serial port(s) if you are absolutely certain that auxiliary devices such as modems; printers; mice; etc.. are USB based and that your PC has enough USB ports to accommodate all of your auxiliary devices. Note: If at some point in the immediate future, you plan to sell your PC, it might be wise to leave the serial port as is.
What is a quadrilateral both pairs of opossite sides are parellel?
square, rectangle, rhombus...
Where is the USB port?
This depends on the computer or other device. Older computers have no USB ports. Many desktops have them on both the front and the back, while some only have the sockets in the back. Laptops tend to have USB ports on either or both sides. Peripherals tend to have their USB ports on the back or one of the ends.
What do el paso and Laredo have in common?
they are both ports of entry.
What is a IO Panel?
An Input/Output Panel, which can be found on either the front or back of your computer. This panel usually contains USB Ports and both audio- and microphone ports. In some cases there is a Firewire and/or eSATA connector as well.
What ports are available on desktop computers?
Ports are something where you can connect output devices and other devices. Here is a list of different ports you can have: USB ports SD card reader port SATA ports (located on the motherboard)
How are series circuits and parellel circuits alike?
Both take current and energy from the power supply and dissipate power.
What are the advantages and disadvantages of a serial port?
Having a serial port allows you to plug more stuff in you computer. i think The serial technology and the parallel technology are now old technology because of hardware like USB and Firewire. They are ports on the back of your computer. Serial ports transfers bits one at a time in a single file one bit at a time. Parallel ports transfers data 8 bits are a time across 8 wires. There are still serial ports on your computer, a serial port comes in 9 and 15 pins and is a male. Things that used to and sometimes still do connect to them are mice, external modems, PDAs and cameras. Parallel ports have 25 pins and is female. Most the time printers used to connect to parallel ports.The serial technology and the parallel technology are now old technology because of hardware like USB and Firewire.

How does USB work?
A USB port allows you to plug in a variety devices to a computer. The USB port is one of the most popular options when it comes to connectivity and most computer come with one or more of these ports. USB ports work by sending signals through a USB cable. There are four conductors in a USB cable. The outer contacts provide power at 5 volts at up to 250mA, quarter of an Amp. Some add on devices just use the power outlet properties, such as fans, lamps and chargers. The two inner ones send the serial data, both ways. The format and syntax of the serial data is a bit too involved for this posting.
