Local Area Network

When choosing the type of LAN, consider factors such as the size of the network, bandwidth requirements, cost, scalability, security needs, and the physical layout of the network environment. Additionally, consider the types of devices that will be connected to the LAN and the available expertise for managing and maintaining the network.

Assuming the single core cable forms part of a three phase circuit (i.e. you are clamping three single core cables) it is best to install the three cables close togther in what is called "trefoil" formation. This harmonises the Eddy currents of each phase.

There isn't one! Believe it or not, the internet is a conglomerate of 'volunteers' across the world. Yes, there are governing bodies in most countries that maintain and track the domain names. Governments in some countries try to restrict or control access. But ISPs provide servers and some connectivity, the government provides some of the DNS servers and connectiviity, Universities provide some of it, as well as various telecommunications companies. Businesses and other organizations provide parts to meet their needs. It really is amazing that it all works!

In computer networks, a hub is a basic networking device that connects multiple devices in a local area network (LAN). It's often considered a layer 1 (physical layer) device because it operates at the lowest level of the OSI (Open Systems Interconnection) model.

A hub receives data packets from one device connected to it and then broadcasts the packets out to all other devices connected to the hub. It doesn't perform any processing or filtering of the data; it simply repeats the incoming data to all connected devices. This broadcasting method is known as "collision domain" networking, where all devices share the same communication channel.

There are primarily two types of hubs:

1. **Passive Hub**: A passive hub simply amplifies and rebroadcasts the signals it receives without any form of signal regeneration or data processing. It doesn't require any power source and is simply a physical connector for network devices.

2. **Active Hub (or Powered Hub)**: An active hub, on the other hand, requires power and has the ability to regenerate signals. It typically includes additional features like signal regeneration and sometimes includes basic error detection.

Hubs have largely been replaced by more advanced networking devices like switches, which offer improved performance and efficiency by selectively forwarding data packets only to the intended destination device rather than broadcasting to all devices on the network. However, hubs are still occasionally used in very simple network setups or for specific purposes where their characteristics are advantageous.

Im going to assume you mean p2p file sharing on a network like Limewire and not a workgroup your part off.

Its a good way for small bands / artists / video makers etc.. to get exposure

Its a good way for people to share files on the internet

You open yourself up to viruses/spyware/adware/rootkits and lots of other 'malware'

Its generally used to by peadophiles to distribute child porn (on the assumption its harder to trace, than just putting it on a website)

There is lots of music available which is in breach of copyright, which adds to p2p's already bad image

It eats up alot of bandwidth, which you will only fully understand when you get your ISP bill at the end of the month

Cut-through switches cannot detect corrupt packets as they do not perform error checking before forwarding the packets. They simply read the packet header and quickly forward the packet to the destination without performing any packet integrity checks. This means that corrupted packets may potentially be forwarded without detection.

In terms of linguistics, there are typically around 50 common prefixes used in English. These prefixes are added to the beginning of words to change their meaning.

Coworkers . You can also call them your partners? i guss!?

Here are a few scenarios:

Single Device: If you have a very small network consisting of only one device that needs to communicate with the internet, such as a home computer or a small office server, then only one public IP address is typically needed.

Small LAN (Local Area Network): For a small LAN with multiple devices but minimal external connectivity requirements, such as a home network with several computers, smartphones, and smart devices, a single public IP address can be used with NAT to allow all devices to access the internet through the router's single public IP address.

Multiple Servers or Services: If your small network includes multiple servers or services that need to be accessible directly from the internet (such as web servers, email servers, or remote access services), you may need additional public IP addresses to assign to each server/service. However, it's also common to use port forwarding and/or reverse proxy setups to route traffic to these services using a single public IP address.

VPN (Virtual Private Network): If your small network requires VPN access for remote users or branch offices, you may need additional public IP addresses to support VPN connections, depending on the VPN configuration and requirements.

This is very tuff to find wat is vpn hard token, kindly discuss if some 1 knows better

A vpn is used anywhere that information must be protected because it is confidential.

An example of a VPN is when you connect to your work email inbox from a laptop or a PDA decice acrooss the internet.

A client is the requesting program or user in a client/server relationship. For example, the user of a Web browser is effectively making client requests for pages from servers all over the Web. The browser itself is a client in its relationship with the computer that is getting and returning the requested HTML file. The computer handling the request and sending back the HTML file is a server.

802.11 and OSI are two different things. The 802.11 committee is responsible for setting the wireless standards for wireless communication. The OSI model is not a standard at all, but a theoretical model of how communications work and utilizes many standards in that process.

The 802.11 standards are incorporated in the OSI model, at layer 1 and layer 2 of the model.

Wired networks require wires! so they must be run through walls, floors and have the potential of being damaged or loosened thereby shutting down the network and requiring the problem to be located.

You connect two or more computers with a switch. You will need a device to act as a DHCP server and probably a DNS server. If that all sounds over your head, you should probably call someone.

A home router will function as both DHCP and DNS server, and would set up the lan connection for you.

4 pairs of wires.

Ethernet is one of the most widespread local area network technologies currently in use. It is extremely useful for any small networks where cost, reliability, and ease of setup is of high importance. Ethernet is used to cover wide area networks. And the main advantage of connecting your business with Ethernet is Simplicity, Flexibility and Pricing.

Ethernet currently utilized with DSL modems is 10BASE-T. This provides transmission speeds of up to 10Mbps, which is significantly faster than the fastest DSL line speed.
