Peer-to-Peer Networking: Setup, Configuration, and Benefits

Point-to-Point Topology

A type of topology that facilitates communication between two nodes, where one acts as the sender and the other as the receiver. It is the simplest communication between two nodes

Peer-to-Peer (P2P) networking

An IT infrastructure that allows two or more computer systems to connect and share resources without needing a separate server or server software.

By physically connecting computers into a linked system or creating a virtual network.

How can workplaces set up a P2P network?

What resources can be shared in a P2P network?

Files, printers, storage, bandwidth, and processing power.

How is access controlled in a P2P network?

Access is controlled by setting sharing permissions on each computer and can be restricted further by assigning passwords to specific resources.

Easy file sharing

Advantages of Peer-to-Peer Networking

It allows for quick file sharing over large distances, enabling users to access files anytime with minimal delay.

Reduced costs

Advantages of Peer-to-Peer Networking

It eliminates the need for a dedicated server or network operating system and reduces the need for a full-time system administrator.

Adaptability

Advantages of Peer-to-Peer Networking

They allow for easy expansion by adding new clients, making them more flexible than traditional client-server networks, and grow with minimal disruptions.

Reliability

Advantages of Peer-to-Peer Networking

In contrast to client-server networks, which rely on a central server, peer-to-peer networks continue to function even if one computer goes down, spreading traffic across multiple devices to prevent bottlenecks.

High performance

Advantages of Peer-to-Peer Networking

The network's performance often improves as each client acts as a server, contributing resources.

Efficiency

Advantages of Peer-to-Peer Networking

They are designed for efficient collaboration between devices with varying resources, enhancing overall performance and resource utilization.

What materials are needed to set up a Point-to-Point network?

Two workstations (laptop or desktop), two network interface cards (NIC), and an Ethernet crossover cable.

What is the role of network interface cards (NIC) in a P2P network?

They enable computers to connect to the network and communicate with each other.

What is the benefit of having each client act as a server in a P2P network?

It ensures that the system scales efficiently as usage increases.

What is the main advantage of P2P networks over traditional client-server networks?

P2P networks are more flexible, cost-effective, and resilient to failures.

What should be the naming convention for the workgroups on both computers?

Both computers' workgroups should be named exactly the same.

What is an example of a unique computer name for network identification?

Examples include PC1 and PC2.

What should be done after assigning computer names and workgroups?

Reboot both computer systems.

How do you access the properties to change the IP address on a computer?

Go to Start > Control Panel > Network and Sharing Center > Change Adapter Settings.

What should you do after selecting your Local Area Connection properties?

Scroll to Internet Protocol Version 4 (TCP/IP), click it, and select Properties.

What is the default gateway for PC1?

The default gateway for PC1 should be the IP address of PC2, which is 192.168.0.2 and vice versa.

What should be done to the network discovery settings for both computers?

Network discovery should be turned on for both computers.

What is the purpose of enabling file and printer sharing?

It allows files and printers shared from one computer to be accessed by others on the network.

What should you do after entering the IP address and subnet mask on the second computer?

Repeat the steps for configuring the network card as done for the first computer.

What should be done with the public folder sharing settings?

Public folder sharing should be enabled.

What is the significance of network profiles in Windows?

Windows creates a separate network profile for each network you use, allowing specific options for each profile.

What is the purpose of the 'Validate settings upon exit' option?

It checks the settings for errors when you exit the configuration window.

What should you do to ensure both computers can see each other on the network?

Turn on network discovery on both computers.

How can you check if the network is successful on a Windows computer?

Open Windows Explorer and click on Network.

What command can you use in the command prompt to test network connectivity?

Type 'ping 192.168.1.1' and press [Enter].
