|
What are and what do the storage devices do?
|
A storage drive reads or writes information to magnetic or optical storage media. The drive can be used to store data permanently or to retrieve information from a media disk.
Storage drives can be installed inside the computer case, such as a hard drive. For portability, some storage drives can connect to the computer using a USB port, a FireWire port, or an SCSI port. These portable storage drives are sometimes referred to as removable drives and can be used on multiple computers. |
|
|
Common types of storage devices?
|
* Floppy drive
* Hard drive * Optical drive * Flash drive * Network drive |
|
|
Floppy Drive
|
is a storage device that uses removable 3.5-inch floppy disks.
These magnetic floppy disks can store 720 KB or 1.44 MB of data. In a computer, the floppy drive is usually configured as the A: drive. |
|
|
Hard Drive
|
The hard drive is used as permanent storage for data.
In a computer, the hard drive is usually configured as the C: drive and contains the operating system and applications. The storage capacity of a hard drive is measured in billions of bytes, or gigabytes (GB). The speed of a hard drive is measured in revolutions per minute (RPM). Multiple hard drives can be added to increase storage capacity. |
|
|
Optical Drive
2 Types |
An optical drive is a storage device that uses lasers to read data on the optical media.
2 Types * Compact disc (CD) * Digital versatile disc (DVD) CD and DVD media can be pre-recorded (read-only), recordable (write once), or re-recordable (read and write multiple times). CDs have a data storage capacity of approximately 700 MB. DVDs have a data storage capacity of approximately 8.5 GB on one side of the disc. |

|
Different types of optical media
(7)` |
CD-ROM – CD read-only memory media that is pre-recorded.
CD-R –CD-recordable media that can be recorded once. CD-RW – CD-rewritable media that can be recorded, erased, and re-recorded. DVD-ROM – DVD read-only memory media that is pre-recorded. DVD-RAM – DVD-random access memory media that can be recorded, erased, and re-recorded. DVD+/-R – DVD-recordable media that can be recorded once. DVD+/-RW – DVD-rewritable media that can be recorded, erased, and re-recorded. |
|
|
Flash Drive
|
A flash drive, also known as a thumb drive, is a removable storage device that connects to a USB port. A flash drive uses a special type of memory that requires no power to maintain the data.
|
|
|
Drivers require what?
|
Drives require both a power cable and a data cable.
A power supply will have a SATA power connector for SATA drives, a Molex power connector for PATA drives, and a Berg 4-pin connector for floppy drives. The buttons and the LED lights on the front of the case connect to the motherboard with the front panel cables. |
|
|
Data cables do what?
|
Connect drives to the drive controller on the motherboard.
|
|
|
Random Fact
|
NOTE: A colored stripe on a cable identifies Pin 1 on the cable. When installing a data cable, always ensure that Pin 1 on the cable aligns with Pin 1 on the drive or drive controller. Some cables may be keyed and therefore they can only be connected one way to the drive and drive controller.
|
|
|
Input/Output ports (I/O) do what?
Common cables and ports? |
Connect peripheral devices, such as printers, scanners, and portable drives.
* Serial * USB * FireWire * Parallel * SCSI * Network * PS/2 * Audio * Video |
|
|
Serial Ports and Cables
|
Serial ports transmit one bit of data at a time.
Ex of Serial Devies - Modem or Printer |
|
|
USB ports and Cables
Can be found where? Support up to how many devices? Can it power devices eliminating the need for an external power source? |
Users can connect and disconnect the devices while the computer is powered on.
A USB hub is used to connect multiple USB devices. A single USB port in a computer can support up to 127 separate devices with the use of multiple USB hubs. Some devices can also be powered through the USB port, eliminating the need for an external power source. |
|
|
What is Firewire?
Support up to how many devices? |
FireWire is a high-speed, hot-swappable interface that connects peripheral devices to a computer.
Supports up to 63 devices. Some devices can also be powered through the FireWire port, eliminating the need for an external power source. |
|
|
What is a paralel port?
|
A parallel port on a computer is a standard Type A DB-25 female connector.
The parallel connector on a printer is a standard Type B 36-pin Centronics connector. Some newer printers may use a Type C high-density 36-pin connector. Parallel ports can transmit 8 bits of data at one time and use the IEEE 1284 standard. To connect a parallel device, such as a printer, a parallel cable must be used. A parallel cable has a maximum length of 15 feet |
|
|
PS/2 Port?
|
Connects a keyboard or a mouse to a computer. The PS/2 port is a 6-pin mini-DIN female connector.
The connectors for the keyboard and mouse are often colored differently. |
|
|
Audio Ports?
Different types? (4) |
An audio port connects audio devices to the computer.
Line In – Connects to an external source, such as a stereo system Microphone – Connects to a microphone Line Out – Connects to speakers or headphones Gameport/MIDI – Connects to a joystick or MIDI-interfaced device |
|
|
Video ports?
5 Types? |
A video port connects a monitor cable to a computer.
Video Graphics Array (VGA) – Provides analog output to a monitor. Digital Visual Interface DVI provides a compressed digital output to a monitor. DVI-I provides both analog and digital signals. DVI-D provides digital signals only. High-Definition Multimedia Interface HDMi provides digital video and digital audio signals. S-Video provides analog video signals. RGB- has three shielded cables (red, green, blue) with RCA jacks and provides analog video signals. |
