1. What does 'ignore volume ownership' do in the Finder?
This ignores any ownership rules and will grant any logged-on user unlimited access to the contents of the volume.
The loginwindow process logs all users out and then tells the kernel to quit all remaining system processes.
Locally connected volumes are fully accessible to any logged in user.
Interface is any channel through which networks data can flow. Hardware network interfaces are defined by physical network connections - while virtual network connections are logical network connections on top of hardware connections. Protocol is a s

2. What are the min sys req for BootCamp?

System launchd is responsible for starting every single system process. It manages system initialization and launches loginwindow.
Absolute always start at the root of the filesystem - whereas relative paths start where the user is current at
Standard - Admin - Guest - Sharing-Only - Root
Client software is used to access services provided by a server

13. How does network service order affect network connectivity?
IP addresses identify the location of a specific network device. Subnet masks are used by network devices to identify their local network range. IPv4 addresses are a 32-bit number represented in 4 groups of four octets separated by periods. 0-255.

Devices providing network services broadcast their existence and Mac OS X picks up on these broadcasts and provides a list of services.

19. What is a device driver? What three primary types of device drivers are there?
The network service operates or broadcasts on a network port.
A driver is a piece of software designed to facilitate the communication between Mac OS X and the peripheral. There are kernel extensions - framework plug-ins - or stand-alone applications.
It starts with a full copy of the system and then it records any changes made to the system and only copies those changes. It creates a simulation of the entire system using hard links for files that didn't change.
