Master the P2P Network Models

Computer Networks

• A computer or program that provides a service, such as data or other resources, to other devices is called a server.

File Server

• The purpose of a file server is to provide a central location for storing and sharing files among multiple users.
• In a given scenario, a folder created on the file server is called a shared folder.
• Four user accounts are created on the file server in the given scenario.

User Accounts

• The usernames and passwords must match between the user accounts on the workstations and the file server.

Windows Server

• When Windows Server controls network access to a group of computers, it is called a domain.
• The centralized directory database that contains user account information and security for a group of computers is called Active Directory.
• The process of a user signing on to the network and accessing resources allowed by Active Directory is called authentication.

Client-Server Network

• A computer making a request from another computer is called a client.
• Clients on a client-server network access resources on another computer by sending requests to the server, which then provides the requested resources.

Network Models

• A peer-to-peer network is a type of network model that is responsible for controlling access to its resources without centralized control.
• In a peer-to-peer network, the computers are called peers.
• Operating systems that might be installed on computers in a peer-to-peer network include Windows, macOS, and Linux.

Advantages and Disadvantages of Peer-to-Peer Networks

• An advantage of using peer-to-peer networks is that they are relatively easy to set up and manage.
• A disadvantage of using traditional peer-to-peer networks is that they can become difficult to manage as the number of users increases.
• A client-server network is more expensive to set up and maintain compared to a peer-to-peer network.
• As a peer-to-peer network grows larger, it becomes increasingly difficult to manage and maintain.
• Traditional peer-to-peer networks are not necessarily secure.
• The recommended number of computers for a peer-to-peer network is 10 or fewer.
• An example of a mobile operating system that might be installed on devices in a peer-to-peer network is Android.
