It is true that a PC can work as the network server. It is also true that lot many people turn their old computers in to the home servers. But it is wrong to say that PC can replace the real server. The needs of the home or the small organizations might be too small and hence they can use the desk top PC as a server. The first point is that a server has to function for 24 hours a day and 7 days a week. For this you need a special device. There are lot many features that you will find only in the server for your network and not in the desktop PC. Your server will have duel processors. It can have hot swappable components. This means you can change them while the work of the unit is going on simultaneously without any harm.

The other important features that you can find in the network server example will be redundant hard drives and power supplies. It will be scalable and it will not only meet the present demands but will meet the future demands also. The server will process data faster and more efficiently. You can take any network server example and get these parameters confirmed.

We are considering the file server as the network server example. The most important work that it does is protecting and keeping the files secure the access to the files is fast. Suppose that one work station fails then you can go to another work station and can access the files easily. In any company there are different levels of managements. You do not want all sorts of people to view all types of files. This is possible in this type of file server. Each person can have his personal folder to store files at his level. These files will also get all the back up of this server system.

There is always increased reliability in this type of file server. If one power supply fails, then another back up will start immediately. There will not be loss of data and the productive time. This same thing also applies to the hard drives. If a hard drive gets corrupt, the work does not stop and there is no loss of data also. The hard drives in this server are of hot swappable type. This means you do not have to shut the whole server down to replace the corrupt hard drive. The virus management in the server will be of top quality. There is always centralized back up system in this type of network file server. I hope I have explained well the concept of the server with the help of this network sever example.

Ethernet is the term coined by Robert Metcalfe of PARC for the system he developed to power the new laser print in his office building. In the early 1970's this was new challenge, as the Xerox printer was connected to a large number of computers with the building. These computers formed a local area network or LAN. The system of cabling that Metcalfe developed to send pages to the printers where christened Ethernet. The term was chosen because it was once believed that ether, an unseen material, connected all things in the universe.

Ethernet is now the most common method of connecting a local network of computers. It differs from the internet as the Ethernet tends to connect machines within a predefined network and often within a set location; it is not open to public access. The network will be built around a system of cables and switches and not the public telephone system which powers the internet. If you work in large company then more than likely your intranet will be part of an Ethernet network. Network terminals, normally computers are connected together in order to share information quickly and securely.

Standard Ethernet is able to provide fast and constant connections. A standard Ethernet cable can handle about 10,000,000 bits per second and can be used with almost any kind of computer. The problem is that with the increase in file size and the ever increasing demand for data there is increasing pressure for a system that provides a fast Ethernet network to match the needs of users.

The result of this is that the standard speed limit of 10 megabits per second has rocketed to 100Mbps for fast Ethernet network's and 1000Mpbs for Gigabit Ethernet networks. This development has resulted in super fast networks that can carry and process massive amount of data. The development from a network for a single printer is one of the wonders of the modern age.

In the present scenario, technology has made enormous amends, as well as played an imperative role in changing yesterday's world into the most recent high-tech world. It is a fact that the high speed internet has made world come closer and made the communication easier, as it provides soothing communication with the improvement of cost-effectiveness. You can even do a lot more on your computer and laptop without any hassle, as the broadband offers very high speed to surf the internet.

Due to higher advancement, broadband internet is distinct as the high speed internet. And this offers the users to access information through the internet at a quick speed compared to the dial-up access over the modem. There are many broadband deals in the market and the users can avail them as per their needs and pockets.

As a result, it becomes more popular among the users for accessing the web and it is used to activate information on the desktop or laptop computer extremely easily. This latest technology touches the user's operations with a speed ranging from 64 bits to 1.0M bits. It makes flawless high-speed connection with immense outcomes. But the high speed internet is only achievable, when the users use with a built-in high-speed modem.

In a choice of forms, the users can gain the broadband internet connection such as DSL, cable or satellite. That means DSL stands for digital subscriber line, which allows spreading a high quantity of data, voice, images and videos very speedily. However, the most important thing is to search for the best broadband deals in the market. It means you will hit upon relatively perplexed about the deal to select from the huge market.

There are some broadband deals, which regularly propose additional features, such as virus protection. While some are free, others are added for an extra charge. It is very obligatory for you to confirm the small print of the deal whether the free offer is only available for a trial period or may be you can get the extra feature cheaper as a separate package. You can go through various online to avail the best and profitable broadband deals.

When dialup refuses to receive any data, even though your browser or other program is trying to send data, it can be frustrating, especially with a deadline. The following short series of steps can keep your dialup receiving data without a delay.

1. If you don't have a browser that can refresh the page, get one. Opera works well for me, and it's faster than Internet Explorer in the first place.

2. Load a page such as Wikipedia.org (Not the homepage). It is large enough so that it doesn't completely reload from the cache when it refreshes, but small enough that your dialup doesn't just "give up" on the page.

3. Set the page to reload every second. In Opera, right click anywhere in the window and select "Reload Every". Select "Custom", then enter 1 second in the dialogue box that follows. Make sure to click "Enable", then click OK.

I suggest locking the Wikipedia tab so you don't accidentally close it and allow the connection to stop transferring data. Also note that this will use bandwidth, so expect a tiny drop in your speed on other pages. Finally, 1 second might be more frequently than you need, so adjust the time accordingly.

This does not seem to work for connections that disconnect, but is for connections that seem to go dormant. Sometimes this will not work, and your only other option is to disconnect and reconnect. If your connection seems dormant on your third connection, disconnect and try dialing your ISP from a phone and listen for any abnormalities.

A simplified summary of the specs for the most common categories in use today can help you determine what is right for you.

FREQUENCY-DISTANCE
Category 5-100 mbps-100 meters (328 feet)
Category 5e-1 Gigabit/sec-100 meters (328 feet)
Category 6- 3 Gigabit/sec-100 meters (328 feet)
Category 6A- 10 Gigabit/sec-100 meters (328 feet)

If you have very short runs, you may be able to use the cable at a lower rating than officially required. For example, on a 10 Gigabit application it is usually possible to go up to 35 meters on a Category 6 cable. Another possible application is a 30 foot run at 3 Gigabit on a Cat 5e cable which should work correctly because its such a short run. If you have the luxury of trying out short applications you may be able to operate with cable rated at one lower category than the 100 meter rated cable for the required speed.

There are also considerations when the cable runs near power lines or fluorescent lights where there is a possibility of increased crosstalk, that may have to be dealt with. In a well designed Data Center cable layout, there are often 4 separate layers of cables including copper cables, fiber cables, power cables, and ground lines. Certain cable layouts have crosstalk considerations that can indicate the use of (ScTP) overall shielded pairs, or (STP) shielded pairs and overall shielding rather than (UTP) unshielded twisted pair cable.

Installation is also very important to make sure that the system supplies the standards that the components are designed to. Sloppy punch downs on the 110 Patch Panels may effect the system operation.

Also a Cat5E Jumper put serially into a system of Cat 6 cable components will bring the entire Cat 6 run down to a Cat 5e level or less.

Finally it is important to design the data system with the future requirements in mind. If the system will have to be upgraded in the foreseeable future to handle higher frequencies or longer runs or a combination of both, it is usually much more costly when the labor charges are taken into consideration to have to make any major changes. Therefore the level of cable should include the increased capability required in the future, on the initial installation.

A new breed of internet business enterprises was born with the growth of the internet as the most preferred medium for communication and business activities. These new pioneers mushroomed across the globe, anticipating a spectacular rise in the number of clients wanting access to the Internet and related services. The new class of business enterprises, popularly known as Internet Service Providers were engaged in fulfilling the needs of the millions of internet users by providing them secure and speedy access to the Internet.

In strict technical terms, an ISP is an enterprise that offers users access to the Internet and related services. They provide services such as Internet transit domain name registration and hosting, dial-up access leased line access and collocation . Typically an ISP charges a monthly access fee to the consumer based on either internet usage hours.The client then has access to the Internet, although the speed at which this data is transferred varies widely depending on the technology used. They usually have infrastructures like communication setups, high-end servers and is connected to the national internet backbone through gateways with great bandwidth and reliable security protocols.

To understand the Internet Service Provider we must understand Internet connection methods. The internet data transfer speed can generally be divided into two categories, namely dialup and broadband. Dialup connections require the use of a phone line, and usually have connection speeds of 56KBPS or less. Broadband on the other hand, can be either ISDN Broadband wireless access, Cable modem DSL Satellite or Ethernet. Broadband provides always-on internet access and varies in speed between 64KBPS and 20MBPS. With the increasing popularity of file sharing and downloading music and the general demand for faster page loads, higher bandwidth connections are becoming more popular and the internet service providers are under pressure to upgrade to the latest trends in order to keep pace with the growing customer demands.
The ISP's role is to provide any services beyond just Internet connectivity, such as e-mail, web hosting, and technical support. The ISP must perform all authentication and accounting functions necessary to provide access and then bill their users for it. ISPs have several multiple tier set-ups involving smaller ISPs to increase returns on investment and to efficiently manage a geographically large, high capacity network. Such a model with a network of smaller ISPs as customers of the larger ISP can be deployed to serve customers in locations where internet access could not have been provided by a single ISP.

The Internet Service Providers have survived through some testing times with governments taking their own sweet time in taking vital decisions relating to bandwidth and other internet-related matters. Commercial use of the Internet began in the early 90s. Connecting to the Internet in the beginning proved to be quite a challenge. Users had to figure out how to create dial-up connection on their own using Windows early versions. As the Internet gained momentum the technology began to evolve. Faster connections and easier software became available. V.90 which brought download speeds up to 56k or 56,000bps developed in 1998. Larger companies, began to offer Internet services.

Technologies changed fast and newer ones appeared on the internet scenario with monotonous regularity.Broadband, DSL, Cable Modems, Ethernet, you name it , the technology was there. Pricing, technology, and market share drove the Internet economy and the Internet Service Providers had to survive some fierce competition. Many small ISPs began using wireless technology to provide broadband access. Use of wireless technology fueled the way for wireless networks that are in common use today.Internet became fast and furious and ISPs were seen struggling to stay ahead as best possible. The Internet market seemed to settle and ISPs began to move forward. Broadband today has become the connection of choice. DSL and cable modem are the most popular broadband connections. Wireless Internet is still offered but has become more popular on mobile hand-held devices.

With the initial wobbles and shaky starts overcome, Internet Service Providers have today become the stable and secure manner of access to the internet. Encryption technologies, Secured Socket Layers and other accepted forms of internet security together with leap-frogging connection speeds have established these ISPs eliminating the threat of another dot.com crash and bringing great economic viability into this new breed of web enterprise. The debacles of the past could now be swept under the carpet.

Revolutionary technologies, brave new thrust areas and a great new will for survival have brought the ISPs to a crucial turning point in their existence. Today it is not a question of mere existence but one of qualitative existence. Bottom lines are crucial as they always were,but a new meaning has come in where the emphasis is on technology and quality rather than mere run-of-the mill services. The Internet Service Provider has truly entered an era of exciting new range of services apart from providing quality internet access through innovative new technologies.

Broadband is now the most common type of internet in households. It's is now actually pretty hard to find somebody using a dial up modem for their connection. Most broadband providers also supply a wireless router either for free of for a very cheap price, and with most laptops having an integrated router inside them as standard, broadband just keeps getting easier and easier.

Wireless broadband sends signals from your router through your house and beyond. Most household routers have a dependency range of around 45 meters, so the signal can be easily picked up by surrounding households if it is not protected.

If somebody is able to access your broadband connection you risk several things. There is of course the risk that by connecting to the network they can access your files and place viruses on your PC and therefore damage your machine. This is a practice that is on the rise in the united kingdom, with many people getting a kick out of being able to crack peoples passwords just for fun.

However, they can also affect you negatively in less malicious, but still harmful ways.

For example, if somebody logs onto your network and begins to download a large video file, they will slow down your internet's speed and performance by a huge amount. The longer they can get away with this, the worse off you are. Many broadband companies have a "bandwidth" or "download limit", and if somebody else is using it up for their own means, you lose out entirely.

Apart from direct attacks on your machine, there is also the risk of them looking at your history and possibly getting hold of your passwords and usernames meaning they could access highly personal information. Never store your banking details, credit card numbers or contact information on your PC.

If they take part in illegal activity such as phishing schemes, downloading music and movies illegally, or worse dealing in highly illegal products such as drugs and pornography, using your internet is a perfect way for them to shift the blame, as all of the connections are under your name. It is also very hard to prove who has accessed your network if you are in a densely populated area.

So for these reasons it is really very important that you limit who can access your broadband. It is usually a simple process to protect yourself, and nowadays broadband providers often supply you with the correct tools and software.

Make sure you have a good look at what you have been supplied with and use it to the best benefit that you can.

So, now you've got your broadband package and you are raring to go! But first, make sure you are secure and safe to do so without being prayed upon by the evils of the online world.
If you bought a "package" with a broadband company there is most likely a CD-ROM in the box your other pieces arrived in. You should check it to see if it includes a "firewall".

Installing firewall software stops people online and in your area accessing your files, removing and adding to them. There is usually a free trail period on these before you need to begin paying, but be aware that there are plenty of free virus protection programs available online, such as Avast!, which is just as good.

Once you set up your router and broadband, you will be able to access the settings via software on your PC. Do this right away so as not to allow people to access your computer files before you finalise your settings.

The first thing to do is to check if there is an option for the network to be public. This is often on "allow". Change this immediately, and then remove the default passwords and usernames and change them to something completely different.
Try to use a password that is at least 8 characters long, with numbers, letters AND symbols if your program allows it. You must remember that hackers enjoy a challenge, so you need to make the passwords as personal and private as you can - so no birth dates or street names!

When you are on your router set up menu, there should be an option for you to enter an IP code that you can enter onto all the machines you wish to be able to access the network. Change this from the default as soon as possible. It may be advisable to update this every couple of months, just so you can ensure nobody is going to come close to working out what it is.

There will be express instructions with your router on how to secure it, and you should try to implement as many of them as you can.

Unfortunately, every time the broadband and internet businesses bring out more ways to help keep customers safe and secure, the internet criminals are developing more ways to barge through the barriers. Hacking is becoming more popular than ever due to more people being online. Try to keep as hidden and protected as possible.

With Ofcom revealing that over half of all households in Britain have Broadband, compared to just 39 per cent a couple of years ago and then a seven-fold increase over the last five years, it is no wonder that there is now a more widely spread concern that people are not getting the broadband speed that they have been promised.

This is one of the reasons why communications regulator, Ofcom, have decided to take action.

The organisation has said that they will launch a voluntary code which will mean that internet providers will have to publish their broadband speeds accurately.

This code is being put in practice in an attempt to make all broadband speeds clear to customers. There are a total of 32 providers who have agreed to reveal their accurate broadband speeds to enable customers to spot which offers who be best for them.

Ofcom have said that this idea has been put in place to make sure that people are clear between the speeds that they think they will be getting and the speeds that they will actually get.

With this new code in place there will be 90 percent of UK broadband customers catered for. This code will also mean that service providers will have to resolve any technical issues that people may experience and also allow their customers to change to a cheaper deal if the one they were on was not completely accurate.

O2 have said that they completely approve this code and have commented that it could help reduce any frustration that their broadband customers may feel if they do not have the full information.

If people aren't sure what speed their broadband is then it is possible to find out by conducting a broadband speed test that is available from many websites.

New Anti-DDOS Technology resulting from left of field thinking about how to defend against a "Distributed Denial of Services Attack". Initially it was thought that a software solution, might by itself be able to eradicate the problem. Current mainstream defense utilize mainly hardware solutions like "The Planets" Cisco Guard.

Any Hosting Company would know that the cost to host companies begins at ~ $90,000 US.D. just for the base equipment, and then increase that to ~ $150,000 and one is getting close to a state of the art hardware solution.

Other less expensive solutions involve combined tri-plex solutions utilizing part hardware, software, and staff intrusion management. (i.e. some one must get out of bed and flick a switch)

These tri-plex models can be automated to some degree, but still require personal system manager monitoring.

Anti-DDOS engineers know that for most small businesses and domestic server web sites, the costs of either of these solutions is prohibitive, and that many such clients have been forced right out of business.

The New Hi-Tech solution deploys a carefully thought through means of identifying the point of ddos exploitation and approaching the problem that way, as apposed to identifying the type of threat. DDOSBOTS specifically target certain hardware, and software weaknesses in existing systems. Symntec Intel shields these weaknesses utilizing its advanced tailored design to accommodate these weaknesses, denying DDOS access to exploitive areas. As this technology is literally just off the shelf, the nature and scope of the design and system can not yet be revealed.

If plans considered by ministers go through, people who download illegal music or films could be cut off from their internet.

This comes after talk that internet service providers (ISPs) could be legally obliged to crack down on their customers who are accessing illegal, pirated material.

This action would take the form of a "three strikes and you're out" policy, whereby they would first receive an email warning them to stop, then a suspension and if the illegal downloading continued their contract with the broadband company would be terminated.

Those broadband firms who do not take action and don't enforce the rules could end up being prosecuted and then the details of the suspected customers made accessible to the courts.

There are around 6 million people in the UK who are expected of downloading pirated files and this is costing the film and music industry billions as a result of lost takings.

As a result of many people file-sharing it becomes clear why our internet has to work hard to keep up with the demands put on it. When a 30 minute TV programme is downloaded, it is equivalent of receiving 200 e-mails every day for a year. This is why when you compare broadband speeds, they are all relatively low. However, with broadband speeds from some European countries being much faster, there seems no reason why the UK speeds can't improve.

Some of the major ISPs have discussed a voluntary scheme for policing pirate downloads. However, some difficulties could include how to prove who was using the internet for file-sharing.

The Internet Service Providers Association has said that the best cure for this problem is self-regulation.
