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

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

Transmission Control Protocol/Internet Protocol
