Local Area Network

Yes, G652D is a standard for single-mode optical fiber cables. It is commonly used in telecommunication networks due to its low attenuation and reliable performance for long-distance communication.

It is a technically challenging field that provides valuable products to society. It also pays very well and job security and growth are strong and projected to stay strong. Generally you study it if you liked math (calculus), chemistry, and physics in high school and want to apply this, and more complex technical knowledge to the real world.

While mechanical engineers often deal mostly with water, steam, and air, chemical engineers have the opportunity to deal with any chemical in existence, which can make the behavior very interesting sometimes. It is also important to distinguish chemical engineers from chemists: chemists are concerned with the possibility of making new chemicals and figuring out the chemical pathway to achieve this goal on a laboratory scale. A chemical engineer is concerned with the industrial scale production and the processes, equipment, and economics used in carrying this out.

RTK stands for Real Time Kinematic (GPS). Briefly, it is a way of using two (or more) earth based GPS units to solve the inherent ambiguities in the GPS system, to arrive at a submeter (usually 5cm or less) position solution.

It is difficult to take the same size pace every time, especially over rough ground.

It is hard to walk in a straight line. Also there is a chance for error in measuring the length of your paces even if they are all the same size. A small error here would compound if you take a lot of paces.

To add servers to a LAN for optimal performance, follow these key steps:

Network Topology and Design:

Assess the current network layout and use a hierarchical star topology.

Segment the network using VLANs for reduced broadcast traffic and improved security.

Switches and Routers:

Invest in high-performance, low-latency switches with features like QoS and link aggregation.

Configure QoS to prioritize critical traffic.

Network Cabling and Ports:

Use high-quality Ethernet cables (Cat6a or Cat7).

Ensure sufficient Gigabit or 10 Gigabit Ethernet ports for new servers.

Server Configuration:

Equip servers with high-performance NICs and consider NIC teaming for increased throughput and redundancy.

Implement load balancing to distribute workloads evenly.

IP Addressing and DNS:

Use a structured IP address scheme and consider DHCP for dynamic IP allocation.

Ensure correct DNS configuration for efficient name resolution.

Security Measures:

Implement firewalls, ACLs, and IDPS to protect servers.

Keep systems updated with the latest security patches.

Performance Monitoring and Optimization:

Use network monitoring tools to track performance metrics.

Conduct regular performance audits and adjust configurations as needed.

Scalability and Redundancy:

Design the network for scalability and future growth.

Implement redundant links and hardware for high availability and resilience.

Following these steps will help you integrate new servers into your LAN efficiently, ensuring high performance and reliability.

Generally speaking, UTP of Cat5, Cat5e, or Cat 6 is physically terminated with either an RJ-45 plug or RJ-45 jack.

The wiring pattern depends on whether you are using 568A or 568B as your cable standard.

The major benefit of a switch over a hub is the increase in the amount of collision domains. This allows a switched network to benefit from full duplex transmissions, negating the need for CSMA/CD, and doubling the potential throughput for each network segment. Switches typically operate at layer 2 of the OSI model, using destination MAC addresses within the Ethernet frame to intelligently filter or forward packets.

Total internal reflection explains how fiber optics can transmit light pulses over large distances with minimal loss in signal strength. Light pulses undergo multiple reflections within the fiber core due to the core being made of a material with a higher refractive index than the cladding, ensuring that the light remains confined within the core and travels long distances without significant loss.

Hi I believe you are talking about DNA transfer of genes and I believe it's a transfer of different gene coding which are not Identical. If A is on X chromosome and B is on Y then through recombination A will be on Y and B will be on Y.

It can range very widely. They can go from 5 mega bits per second to 50 giga bits per second. (with different types of cabling.) In Sept 2009, in their lab, Alcatel-Lucent achieved a speed of 2 Peta bits per second over 7,000KM. That's over 100 million Giga bits per second.

Yes, you can convert a Chapter 13 bankruptcy to a Chapter 7 bankruptcy, but you'll need to meet the eligibility requirements for Chapter 7, such as passing the means test. You'll also need to file a motion with the bankruptcy court requesting the conversion and provide documentation to support your request. An attorney can help guide you through this process.

Answer I had the exact problem with a former girlfriend and it really pissed me off. I asked her what was the idea of introducing me as her friend and not her boyfriend and she replied that she wasn't ready to introduce me that wasy so my advice to her was when you are ready to recognise me for who I am then call me and until then don't bother. The next day she called and appoligised saying she was wrong and could we put this behind us. We did and it worked out well. You do as you wish, but if it were me I'd take affirmative action and not let him get away with that nonsense.

Anemometers are useful today for measuring wind speed and direction, which is valuable for a range of applications including weather forecasting, aviation, and assessing environmental conditions for activities like wind energy generation. They provide real-time data that helps in making informed decisions related to safety, operations, and planning.

Fiber optics offer higher bandwidth and longer transmission distances compared to copper cabling. Fiber is also immune to electromagnetic interference and is more secure due to its low signal loss and difficulty in tapping. Additionally, fiber is lighter and smaller in diameter, making it easier to install and maintain in large interbuilding networks.

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.
