Transcript of Demystifying Mac Pro

Power Supply
The power supply supplies and regulates the electrical load in the computer system.
Central Processing Unit (CPU)
This is the hardware inside the computer that performs the input/output (I/O), mathematical, and logical operations of the system which enable computer programs to run.
Logic Board
The term “logic board” refers to Apple-brand motherboards. A motherboard is the main printed circuit board in the computer which holds many of the most important components in the system. The CPU, memory, and connectors for other peripherals are located on the logic board.
Monitor Port
The monitor port, or display port, is the interface used to connect the video output of the computer system to a display device, such as a monitor. This connection can also be used to carry audio, USB, and other forms of data.
Network Port
A network port enables a computer to connect to the internet through an ethernet connection. It serves as a communication endpoint in the user's computer system, and allows for communication with an Internet Service Provider (ISP) and access to the World Wide Web.

Mac Pro

Drive Bay
A drive bay inside a computer case is a standard-sized space for adding additional hardware to a computer.
Hard Disk Drive (HDD)
A hard disk drive is the place where digital information is stored and retrieved from in a formatted order by a moving actuator arm. Mac Pro uses the NTFS (New Technology Film System).
The HDD contains platters (rotating disks) coated with magnetic material, and is able to hold onto its data even when it is powered off.
Backup Battery
A backup battery, also known as a clock battery or PRAM (parameter RAM) battery, provides power to the computer when the primary power source is unavailable. This allows small packets of data to remain available for critical startup operations.
Expansion Slots
Expansion slots are areas on the logic board, or other main circuit boards, where additional smaller circuit boards called expansion cards can be inserted to add additional capabilities to the computer hardware.
Device Power Connector
These connectors supply power from the logic board to additional installed hardware throughout the computer system.
Random Access Memory (RAM)
RAM is a form of data storage that allows said data to be accessed in any random order, allowing for efficient computing.
Optical Drive
An optical disc drive uses laser light as part of the reading or writing processes to or from optical discs, such as DVDs and CDs.

Firewire Port
Firewire is a term coined by Apple for the IEEE 1394 interface. Firewire is a serial bus interface standard for high-speed sequential data transfer. It is commonly used with audiovisual components, both for communication and control.
In the top picture, there are two Firewire 800 ports. In the diagram below it, there are both Firewire 400 and Firewire 800 ports. Firewire 800 is twice as fast as Firewire 400, and more powerful over longer cable distances.
USB Port
Universal Serial Bus (USB) is an industry standard for connections, communications, and power supply between computers and peripheral electronic devices. USB indicates a sequential transfer of data.
This Mac Pro has several USB ports, including two on the front of the tower, three on the back of the tower, and three on the back of the monitor displayed.
Power Switch
The power switch, in this case, is a button that powers on the computer system. It may also be used to power down the system.
First Up -->> Internal Hardware
The power switch plugs directly into the computer's logic board.
