Network Essentials Chapter 1
Windows Domain
When Windows Server controls network access to a group of computers
Network
A group of computers and other devices (such as printers) that are connected by and can exchange data via some type of transmission media, such as a cable, a wire, or the atmosphere
Client-Server Network Model
A network where resources are managed by the NOS via a centralized directory database
Server
Any computer or program that provides a service, such as data or other resources, to other devices
Layers of OSI Model
Application Presentation Session Transport Network Data Link Physical
Layers of TCP/IP Model
Application Transport Internet Link
Logical Topology
Has to do with software, how access to the network is controlled, including how users and programs initially gain access to the network, and how specific resources, such as applications and databases are shared on the network
Physical Topology
Mostly refers to a network's hardware and how computers, other devices, and cable fit together to form the physical network
NOS
Network Operation System Used for Client-Server network model

Open Systems Interconnection
Peer-to-Peer (P2P) Network Model
The operating system of each computer on the network is responsible for controlling access to its resources without centralized control
TCP/IP Definition
Transmission Control Protocol/Internet Protocol
