For most website owners, a dedicated or shared server is always needed as well as other connectivity services like IP transit. Cheap dedicated servers are steadily becoming popular for web hosting needs. Those in this industry long enough know these terms by heart but for those who are just starting out, all this technical jargon can be confusing. In an effort to make these terms easier, here are the main differences between dedicated and shared servers.
A shared server, as the name implies, is a shared resource among multiple users. On a shared server, a website sits in its own partition that ultimately detaches it from other websites on the same server. Many opt to put their websites on a shared server as this is the most economical in terms of cost. However, this is only a good solution for beginners, individuals, small businesses and organisations that have sites that expect little traffic, require low bandwidth and disk space. Services such as maintenance, security updates and software installation, just to name a few are provided by the website host.
A dedicated server on the other hand is one that solely serves one client. There are two kinds of dedicated servers namely managed and unmanaged servers. Unmanaged servers are configured and managed by the client. Managed servers on the other hand normally include a wide range of services such as operating system and application updates, various system monitoring packages and so on.
Let us breakdown where the two really vary so one who is confused between the two can make an informed decision whether a shared or dedicated server is what he or she needs.
Traffic issues can be a problem on a shared server. When another website on the same server gets a huge amount of traffic, your website can experience slow response time or even downtime. This does not happen on a dedicated server. However, if you really do not expect a lot of traffic to come your way, a shared server is a good option.
Cost can also be a deciding factor. Obviously, shared server costs are a lot more affordable than that of a dedicated server as the costs can be ten times more expensive than shared server costs.
Disk space and bandwidth are important factors. This makes a lot of difference if you expect your website to grow. With dedicated servers you will have all the disk space and bandwidth you can possibly need unlike on shared servers. It is easy to run out of space when you have a growing website. In this scenario, you will have to keep adding space and bandwidth to accommodate your needs.
Security is always going to be an issue. On a shared server, the IP address is also shared. This only means that once one of the sites on the same IP address is banned, yours can get banned too. Websites are usually banned through the IP address instead of their domain name. Also, a website on a shared server can get hacked into by other webmasters. This simply does not happen on a dedicated server.
Preference for operating systems and software can also be a deciding factor. On a dedicated server, you have the option of using your operating system of choice. This can be anything from Windows to Mac to Linux. Of course you will want to choose the operating system that your people will most be comfortable with. This goes the same for applications. On a shared server, these are aspects that you will have to adjust to.
So, depending on the factors above, you can now make an informed decision as to which is it that you really need. It is really up to personal preference and your computing needs whether shared servers or dedicated servers are the choices you should make. If you do want to use a dedicated server but are afraid of the expense, there are reputable providers that offer cheap dedicated servers and also other services like IP transit at an affordable rate. It is all a matter of knowing where to find them.

Chat rooms or “chats” are one of the most interactive
areas on the Internet and they are regularly visited by children and teenagers. Putting it plainly and simply, a chat room is a place on the Internet where people meet to talk about various subjects. Conversation is simultaneous,synchronous and written. A user writes a message onto the computer and the message is immediately displayed on another computer. From a teacher’s point of view, chat rooms may turn out to be one of the best places to engage our students in real and meaningful language practice. From a student’s point of view, chats are an exciting means of communication and an enriching opportunity to communicate with native or non-native speakers in English.
Generally speaking, chat rooms provide students with a stress-free and uninhibited language practice but most importantly they foment linguistic interaction. Much has already been said and written about the utter importance of interaction in the learning and acquisition of a second language. It has already been proved that the more the student (meaningfully) interacts, the more opportunities he/she will have to learn language and the more language the student learns, more input can he/she can solicit in order to learn more language
So, in order to increase students’s interaction in the English language, we can include chat rooms in our lessons. Students’s active participation will allow them to experience and experiment language as a real thing. This type of interaction, although written and not face-to-face, will prove more authentic than a conversation with the teacher, especially because in a chat
room language is no longer a goal but an instrument to pursue other (real) goals
Precautions
However, despite the inherent advantages of using chat rooms for educational purposes, one must be conscious of some dangers:
Students often have a difficult time using computers, which might endanger the activity. A good solution is to provide students with the basic computer skills (using the keyboard, reading from the screen) Chat rooms users often use acronyms and slang that students may fail to understand. A good way to solve this problem is to introduce students to those particular expressions (for instance, prepare a lesson based on Netiquette, which includes specific vocabulary items used on the Internet). Students may be confronted with harassment situations and/or verbal confrontations. This is why it is of utter importance to develop your activities in a moderated chat room and to create your own chat room. A chat room for educational purposes should have published a list of main topics and subjects currently under discussion.
Activities
As an activity, the use of chat rooms has to be considered fluency work; thus, the teacher should only intervene if the students’ mistakes jeopardise communication. It is also necessary to keep in mind that the teacher should only act (during the activity) as a prompter and a resource, in order to allow real interaction.
Activity 1: Who’s who?
Objectives: By the end of the lesson, students should have:
acquired the necessary knowledge about the basic functioning of a chat room (log in, write and read a message, log out); used the English language in a communicative way; demonstrated the necessary skills to make and answer questions; demonstrated their understanding of the dialogue; reflected on their use of the English language.
Procedure:
Students will be told that they will dialog with their classmates in a chat room and that they will play a game called “Who’s who?”. Each student will have a nickname, e.g., a fake identity, and that the objective of the game is to guess the true identity behind the nick. Students must also be instructed to keep their nicknames secret. Students will then be told the address of the chat room they’ll be accessing and, individually, their nicknames. The teacher should help students to log in and make sure everyone is able to send, read and write messages. Students should then approach their colleagues and try to find out who is behind the nicknames. In the end, students will be asked to come to the blackboard and write down the names behind the nicks. It is also very interesting to print and hand out the transcript of one or two dialogues and lead a brief reflection on how students used the English language.
Human Growth Hormone is prescribed by injection and is prohibitively expensive for most Americans. The therapy is not covered by insurance and can easily cost over $1000 per month; who can afford that. So, it shouldn’t come as a surprise that HGH supplements have begun to hit the market. A few pills or a nasal spray are a lot cheaper than thousands of dollars a month for injections.
FDA guidelines state that any product containing less than 2 micrograms of HGH are not considered drugs and therefore do not need FDA approval. So that means any legal supplement of HGH contains less than 2 micrograms of HGH. Most research on HGH has been done based on dosages up to 49,000 micrograms. So you would need to take something like 25,000 doses to equal one injection. Clearly this is not a significant amount of HGH.
So, is it really possible to raise HGH levels through the use of legal HGH supplements? Not significantly, but we can also raise HGH levels by stimulating our pituitary gland to produce more natural HGH. This is a much more effective way to increase HGH and get the benefits it provides. These supplements are HGH enhancers and can be more effective at raising HGH levels in our bodies.
The thing is you need to find a supplement that causes the pituitary to secrete more HGH. Some researchers tell us that certain amino acids can be used to increase HGH production in the body. Specifically arginine, glutamine and lysine have been claimed to increase HGH production in humans. Since some of these cannot be taken in pill form your best bet is to mix the powders yourself and then add them to your usual post workout protein drink. Since HGH is released mostly when we sleep a good solution is to take the aminos prior to bedtime.
There are also a line of homeopathic supplements that are available. The goal of these supplements is to enhance your HGH production as well. By introducing HGH into your body the claim is that it also stimulates additional HGH production. While this does make some sense it has not been proven yet by research.
There’s no doubt that increased HGH levels provide great anti-aging benefits, even turning back the clock to some extent. The question is how do we get sufficient amounts of HGH into our bodies. The supplements available today do some good in boosting normal HGH levels and they are safe. Take the time to research any HGH boosting product you are considering to make sure that it lives up to it’s claims.
