You have already learned that all the components of a computer tie into the computer's CPU by way of the bus. When you need to add a new piece of hardware to your computer, you need to know how to connect it to the bus. In some cases, you can plug the device into an existing socket, or port, on the back of the computer. Most computers have several types of ports, each with different capabilities and uses. Older computers feature only three or four distinct types of ports, but new systems provide a wide array of specialized ports. When a port is not available, you need to install a circuit board that includes the port you need.

All modern computers come with the same basic set of ports. These allow you to connect common devices to your computer. Without these ports, your computer would not boot properly and if it did, you would be unable to interact with the software on the system.

The back of a new computer

It contains several color-coded ports. At first glance, it can be overwhelming. However remember that most plugs only fit where they belong and a mistake is never catastrophic. The most commonly used ports are

Mouse and Keyboard Ports

Accepts the keyboard and mouse plugs. The mouse is always the top port. If you make a mistake and plug the mouse into the keyboard port, the computer will not boot properly.

Two USB ports

These accept any number of devices including cameras and joysticks.

Serial Port

Serial ports are connected to external modems

Parallel Port

Most common uses are to connect older printers to the computer.

Audio Ports

There are typically three audio ports on modern computers. The green speaker port is for your headphones or desktop speakers. The pink microphone port is for a small microphone. The yellow speaker out is designed for serious audiophiles to connect their computer to a home stereo system. Intense gamers or PC movie viewers may employ this option

Network Port

This port allows your computer to plug into a network or use a high-speed Internet connection. You will learn more about networking in Chapter 7, "Networks."

Modem Port

It connects your computer to a phone line. The most com mon use for a modem is Internet access. You learned more about the Inter- net in Chapter 2, "Presenting the Internet."

Monitor Port

Most monitors connect to the three-row port on the right side of the image. This can be found either by the serial port or with the expansion cards. Other monitor options may include connections to a TV.

A PC's internal components communicate through the data bus, which consists of parallel wires. Similarly, a parallel interface is a connection of eight or more wires through which data bits can flow simultaneously. Most computer buses transfer 32 bits simultaneously. However, the standard parallel interface for external devices such as printers usually transfers eight bits (one byte) at a time over eight separate wires.

With a serial interface, data bits are transmitted one at a time through a single wire (however, the interface includes additional wires for the bits that control the flow of data). Inside the computer, a chip called a universal asynchronous receiver-transmitter (UART) converts parallel data from the bus into serial data that flows through a serial cable. How data flows through ninepin serial interface.

As you would expect, a parallel interface can handle a higher volume of data than a serial interface because more than one bit can be transmitted through a parallel interface simultaneously. how data moves through a parallel interface.

• Is A SSD the same as a SCSI?
• Which is better NFS or iSCSI?

The Small Computer System Interface (SCSI, pronounced scuzzy) takes a different approach from standard parallel or serial ports. Instead of forcing the user to plug multiple cards into the computer's expansion slots, a single SCSI adapter extends the bus outside the computer by way of a cable. Thus, SCSI is like an extension cord for the data bus. Like plugging one extension cord into another to lengthen a circuit, you can plug one SCSI device into another to form a chain, as shown in Figure 4B.11. When devices are connected together this way and plugged into a single port, they are called a "daisy chain." Many devices use the SCSI interface. Fast, high-end hard disk drives often have SCSI interfaces, as do scanners, tape drives, and optical storage devices such as CD-ROM drive.

The Universal Serial Bus (USB) has become the most popular external connection for PCs-both IBM-com- Computer patible and Macintosh systems. USB has several features that have led to its popularity First, USB is a hot swappable bus. This means that users can switch USB devices without rebooting the PC. A second feature is its ease of use. Simply plugging the device in makes it ready to run. Finally, USB supports 127 daisy-chained devices. Today, most new computers feature at least four USB ports, with two often in the front of the PPCs both IEEE

• Is FireWire still useful?
• Can I connect FireWire to USB C?

Like the USB standard, the IEEE 1394 (FireWire) standard extends the computer's bus to many peripheral devices through a single port. Because IEEE 1394-compliant technology is so expensive, however, it is not expected to become the dominant bus technology, al though it may gain wide acceptance as a standard for plugging video and other high-data-throughput devices to the system .

The Musical instrument Digital Imperfect (MIDI) has been in use since the early 1980s, when a group of musical incumbent manufacturers developed the technology to enable electronic musical instruments to communicate. Since then, MIDI has been adapted to the personal computer. Many sound cards are MIDI- compliant and feature a special MIDI port. Using a MIDI port, you can plug a wide variety of musical instruments and other MIDI-controlled devices into the computer MIDI systems are widely used in recording and performing music to control settings for electronic synthesizers, drum machines, light systems, amplification, and more.

• What are the 5 type of expansion slot?
• What are the 3 different expansion slots on a motherboard?
• How many expansion slots are on the motherboard?
• What is the most common expansion slot?

PCs are designed so that users can adapt, or configure, the machines to their own particular needs. PC motherboards have two or more empty expansion slots, which are extensions of the computer's bus that provide a way to add new components to the computer. The slots accept expansion boards, also called cards, adapters, or sometimes just boards. Figure 4B 12 shows a PC expansion board being installed. The board is being attached to the motherboard-the main system board to which the CPU, memory, and other components are attached.

Adapters that serve input and output purposes provide a port to which devices can be attached and act as translators between the bus and the device itself. Some adapters also do a significant amount of data processing. For example, a video controller is a of the PC into which you card that provides a port on the back can plug the monitor. It also contains and manages the video memory and does the processing required to display images on the monitor. Similar devices include sound cards, internal modems or fax/modems, and network interface cards.

Another type of expansion card is the PC Card (initially called a Personal Computer Memory Card International Association, or PCMCIA, card). It is a small device about the size of a credit card. This device was designed initially for use in notebook computers and other computers that are too small to accept a standard expansion card. A PC Card tits into a slot on the back or side of the notebook computer. PC Card adapters are also the back for desktop computers, enabling them to accept PC Cards. Even some trues of digital cameras accept PC Cards that store digital photographs. PC Cards are used for a wide variety of purposes and can house modems, network cards, memory, and even fully functioning hard disk drives.

There are three categories of PC Card technologies: Type I, Type II, and Type III The different types are typically defined by purpose. For example, Type 1 cards usually contain memory, Type II cards are used for network adapters, and Type III cards usually house tiny hard drives. Type I PC Cards are the thinnest available and have the fewest uses. Type III card age the thickest and enable de velopers to fit disk storage devices into the card-size shell. Some PC Card adapters can hold multiple cards, greatly expanding the capabilities of the small computer.

With the introduction of Windows 95, Intel-based PCs began supporting the Play and Play standard, making it easier to install hardware via an existing port or expansion slot. Using hardware that complies with Windows' Plug and Play stan dard, the operating system can detect a new component automatically, check for existing driver programs that will run the new device, and load necessary files. In some cases, Windows will prompt you to install the needed files from a disk Depending on how the new device is connected, this process may require restart- ing the system for the new hardware's settings to take effect. Still, this process is much simpler than the one required prior to Plug and Play technology, which usually forced the user to manually resolve conflicts between the new hardware and other components.

(Sell Computer Processing Power) Summary:

• Most of the processors used in personal computers are based on complex instruction set computing (CISC) technology. PowerPC processors, and processors used in many other types of computers, are based on reduced instruction set computing (RISC) technology. Because they contain a smaller instruction set, RISC processors can run faster than CISC processors.

• A parallel processing system harnesses the power of multiple processors in a single system, enabling them to share processing tasks. In a massively parallel processor (MPP) system, many processors are used. Some MPP systems use thou sands of processors at one time.

• External devices, such as those used for input and output, are connected to the system by ports on the back or front of the computer.

• Most computers come with a serial port and a parallel port. A serial port transmits one bit of data at a time; a parallel port transmits one byte (eight bits) of data at a time.

• If the computer does not have the right type of port for an external device (or if all the existing ports are in use), an expansion board can be installed into one of the PCs empty expansion slots. Bus technologies such as Small Computer System Interface (SCSI), Universal Serial Bus (USB), and IEEE 1394 (FireWire) enable the user to connect many devices through a single port.
