Dedicated server hosting is a kind of internet hosting in which a client leases an entire server to one customer only. In other words, in dedicated server hosting website owner takes an entire server on rent form the hosting service provider. This is different from the shared server hosting, where a number of client s use the same service, hence the bandwidth and space is very less.

Many website owners start with shared server when the number of visitors is less. This is the most economical option for hosting the website as overall cost of server maintenance is shared by many people. Moreover the service provider ascertains you with support, security and maintenance. However, in shared hosting, your website faces many problems when there is a sudden surge in the traffic.

Today, more than ever, home networks are easier and less expensive to set up. At times, however, the knowledge needed for building a network is not accompanied by any guidelines on how to secure them.  In some cases, the guidelines are simply ignored. No matter what the case, that is a data disaster just waiting to happen.

You may have a thing about being paranoid about security. That is an excessive amount of concern that should be tempered. However, you should have a certain amount of caution. Security is much like medical insurance. You may not need it very often, but when you do need it, chances are you need it badly. If you don’t have it you may face dire consequences.

Wireless home networks are becoming increasingly popular due to their lower cost and flexibility.  However, the wireless network is particularly prone to security issues. In theory, someone that has a wireless enabled laptop can just drive by your house, get into your space and tap into your network. It’s not too much of a problem if all they do is steal a little bandwidth. However, if they happen to be malicious and clever, they will be able to implant a virus into your home network without you even knowing it!

Using the Internet has similar risks. However, in a case like that you usually have to download an attachment from someone you don’t even know to get infected. This scenario is easy to avoid. As a rule of thumb, if you do not know who it is from, do NOT open it. It could be a hacker with a virus. However, in the case of a wireless home network, you do not have to take any action to get infected. Even though you may be following good Internet file sharing practices, you are still vulnerable.

Even if you have a cabled network, it is possible for someone to break in while you are away. Most of these incidents will revolve around stealing property. But by infecting a computer a disgruntled employee, an angry person or a party to a lawsuit may use this as a way of getting revenge. What a better way to get revenge than to have your computer crash!

The solution is typically the same in either type of network. Practice the same good habits you use for Internet data sharing and magnify them. You must make sure that each computer on the network has a password that is required in order to gain access to the system. Leaving a system unprotected to just save a few seconds of inconvenience at home will expose your entire network to unnecessary risk.

One thing you want to do is change the password on your router often. The defaults for most of the popular vendors’ products are known by just about everyone who has the necessary skills to do harm.  Make it harder for them to inflict damage by following this simple step. Configure your wireless router according to the manufacturers’ instructions in order to prevent unauthorized access. Today, all wireless routers use WAP to prevent drive-by’s from accessing your system.

Most adults today would be astounded by the amount of computer knowledge a teenager has. Most are well meaning, but some young people have not yet learned how to use a home network securely. Some young people can master the techniques, but they do not yet have the common sense or the wisdom to know how to put these techniques into practice.

Treat your home network in much the same way as you would treat your credit cards. You wouldn’t just hand you credit card out to a stranger would you? Moreover, you wouldn’t tell that stranger your password would you? You would be broke in no time! Do not provide physical access or pass out information to anyone that you do not want to have access to it. This is often a short step from having them access your money. It is an even shorter step to your valuable home network as well as your data!

Electronic imaging consumes large amounts of bandwidth and data. Current connections to the home consist primarily of modems running at 33.6 Kpbs or 56 Kpbs. For those users who deal with still images and video, these speeds are not acceptable. The home needs fatter pipes in order to proliferate any kind of imaging services or if someone is trying to sell different types of imaging appliances that intend to use the Internet infrastructure. 

The home user has to contract with an ISP for a flat-rate monthly fee. The ISP usually provides a dial-up line that the consumer uses with s standard modem. The cost of  a dial-up line is usually under $20 a month. Many new technologies have been developed with the consumer in mind in order to increase the amount of bandwidth that will be available to a home computer.

The first hurdle you have to pass is to become more familiar with many of the letters and names. One the terminology is learned, the rest is just common sense and being able to carefully follow directions. One of the very first terms you will encounter, is the word ‘protocol’. The technical definition of the word as well as the acronyms can be very complex. However, for your purpose it is quite straightforward.

A protocol is a set of rules that have been adopted as a means for devices to communicate. For instance, the HTTP protocol used by Internet browsers specifies a detailed list of methods for passing Internet data back and forth. TCP/IP or Transmission Control Protocol/Internet Protocol is a method that dictates how packets get defined and transported on a TCP/IP based network.

Note that there are a variety of ways, involving other protocols, to establish networks and their rules. In days past IBM was one of the earliest with its SNA network philosophy. This was widely used in business for decades. Though it has now been replaced by TCP/IP, it is still in use throughout the world. These are not the only two that have been adopted at one time or another. While the details are only of interest to computer geeks and professionals, there are aspects that affect how a home network builder has to proceed. If you happen to know some of them, you will be able to choose your equipment and design your network intelligently.

For instance, if one of the central parts of the home network gear is the router. However, router come in a variety of types and each one is associated with a certain protocol. Wireless routers may use the 802.11b or 802.11g protocol. It is not important to know the technical definition, but you much know that the first is rated at 11 Mb versus 54Mb throughput impacts your network.

Even though the first is rated at 11 Mb, that is the rate under ideal conditions. The real throughput is approximately 6-7 Mb.  Also keep in mind that there are 8 bits per byte. That is equal to one character of data. So the actual rate is only just about 1/8th of what you actually tend to think of when you go to transfer files. Faster gear that follows the 802.11 standard running at 100Mb should soon be available.

However, most people do not have any reason to care about the details of Ethernet protocol. The standard protocol used in Ethernet networks is 802.3. This helps to do away with some of the strangeness from another cryptic number. It is also helpful to know that 10BaseT is like a synonym for wired Ethernet networks that run at 10 megabits per second. 100BaseT is the standard for cabled Ethernet networks that use equipment running at 100 Mbps.

Every week there will be a new acronym created as well as a new unfamiliar set of numbers. Network designers are among the geekiest in the business! However, if you familiarize yourself with a few of these protocols and related items, you will soon be barking them out with the best of them.
