1.
PS/2 mouse port- It is used to connect a computer mouse or keyboard to an IBM compatible
computer.
2. PS/2 keyboard port - This port is for a PS/2 keyboard
3. S/PDIF Out port- is an audio transfer format interface. It transfers digital audio signals from one
device to another without the need to first convert to an analog signal, which can degrade audio
quality.
4. HDMI connector- HDMI is a digital interface for transmitting audio and video data in a single
cable. It is supported by most HDTVs and related components, such as DVD and Blu-ray players,
cable boxes, and video game systems.
5. DVI connector- It is used to send digital information from a computer to a digital display, such as a
flat-panel LCD monitor.
6. VGA port- VGA cables carry an analog signal as opposed to a digital signal (ones and zeroes). Using
higher frequencies, it's possible to reach a relatively high range of video resolutions. However, video
quality directly responds to cable quality, and doubly so on higher resolutions. Due to this, the
quality of a VGA image can variate notable across different makes of cables.
7. IEEE 1394a (FireWire) port- this port is used to connect to any firewire device. FireWire has largely
been supplanted by USB. Some professional audio hardware still uses FireWire, though; you may
also occasionally find higher-speed IEEE 1394b headers, but they are even rarer.
8. eSATA port- It is an external interface for SATA technologies. It competes with FireWire 400 and
universal serial bus (USB) 2.0 to provide fast data transfer speeds for external storage devices.
9. USB ports- allow USB devices to be connected to each other with and transfer digital data over
USB cables. They can also supply electric power across the cable to devices that need it.
10. RJ45 port- This port allows connection to a Local Area Network (LAN) through a network hub
using a RJ-45 cable.
11. Audio Ports
a. line in (light blue)- enabling users to connect an external audio device. These devices include
CD players, audio mixers, musical instruments, and microphones. They're used to record, play,
and modify the incoming audio.
b. line out (lime)- It allows external speakers, headphones, or other output devices to connect
to the computer, transferring computer generated audio to the devices so that it can be heard
c. microphone (pink)- Plugging a microphone into a jack enables it to send its sound into the
computer or other device
d. side speaker out (gray)- an output port on your audio device where speakers can be
connected to. However, speaker out ports transmits speaker-level audio signals instead of line-
level audio signals. Audio signals transmitted from the speaker-out ports are amplified and are
stronger than line-out signals
e. rear speaker out (black)- this port is used for rear speakers
f. center/subwoofer (yellow orange)- this port is used for loudspeaker designated to reproduce
a low-pitched audio frequencies known as bass and sub-bass , lower in frequency than those
which can be (optimally) generated by a woofer.
12. PCI-E x16 slot- the most common slot for Graphics cards, the PCI Express 16x slots provides 16
separate lanes or data transfer. These are the 16x speed versions, which are currently the fastest.
PCI-E16x allows up to 4 GB/s of peak bandwidth per direction, and up to 8 GB/s concurrent
bandwidth.
13. PCI-E x4 slot- it has have four data lanes. PCI has its own dedicated serial data connections
(lanes) to the host. This allows each card connection to achieve a bandwidth independent of other
cards that may be active in the system. The number of lanes are indicated by the suffix of the PCIe
protocol (×1, ×4, ×8, ×16, ×32).
14. PCI slots- PCI slots are used to Insert or install Add-on cards, such as LAN cards, Sound cards,
Capture cards and TV tuner cards.
15. Super I/O- integrated circuit on a computer motherboard that handles the slower and less
prominent input/output devices.
16. Print Header- is a female connector, or port, on the back of a computer that allows it to interact
with a printer. These ports enable users to send documents and pictures to a printer.
17. COM port- I/O interface that enables the connection of a serial device to a computer. You may
also hear COM ports referred to as serial ports. Most modern computers are not equipped with
COM ports, but there are many serial port devices still in use that use the interface.
18. USB header- physical connectors found on the motherboard for connecting the extra USB ports
found on the PC case.
19. 5 SATA2 connectors- used as an interface for connecting a host bus adapter to a mass storage
device or optical drive. This connector was designed to replace the older connectors, 34-pin, 40-pin,
etc.
20. IDE connector- IDE refers to the types of cables and ports used to connect some hard drives and
optical drives to each other and to the motherboard.
21. 4 DDR3 DIMM Memory Slot- Double Data Rate Type 3." DDR3 is a type of SDRAM that is used
for system memory. It has the ability to transfer data at twice the rate (eight times the speed of its
internal memory arrays), enabling higher bandwidth or peak data rates
22. CPU- responsible for all data processing operations. It saves information such as data,
intermediate results, and instructions (program). It directs the operation of all computer
components.
