Overview of Linux Dedicated Servers

Filed under: Nerd's Lair, School of Technology, University of Hardware — admin at 10:22 am on Friday, October 2, 2009

When it comes to web hosting solutions, the most common choices are the shared hosting plans and web hosting that is exclusive to a single platform - i.e. Linux or Windows based.

Shared hosting is more popular primarily because it is shared. This means that there are only a few users within the pipeline. In some cases, there are even a few hundred or as many as a few thousand users who are using the same server bandwidth.
This is a good setup if you’re just using the server more for leisure but if you’re using the internet as an extension of your business, you will want to go for a dedicated server. This article will take a look at the Linux-based dedicated server and why it can be a suitable solution for both business and personal web hosting needs.

Shared hosting is cost effective mainly because it uses only one server in a location that is designed to host several different websites from all over the world. Costs go down because of the volume. The problem with shared hosting is that it also includes shared bandwidth so you might experience slowdowns. Dedicated Linux servers, on the other hand, will guarantee you larger bandwidth along with your own personal online space. Your website is going to be hosted on a single dedicated server. And since resources are focused only on keeping your website up, reliability level is higher as compared to shared hosting.
The equipment used for dedicated servers is usually the best. High end servers are common to Linux-based dedicated server which is why they make for a suitable choice. You don’t want to find yourself relying on inferior technology servers that are unable to deliver the speed and power that your site and your business requires. Linux servers assure that you’re getting pre-configured and cutting edge facilities.

3 Follows O2 to Post Revenue Growth for the First Six Months of the Year

Filed under: Buyers + Consumers, Life Of Telecommunication, School of Technology — admin at 4:56 am on Tuesday, August 25, 2009

The recent half yearly financial results of the mobile broadband service provider 3 show that the number of its customers has gone up to around 3.8 million. This is almost a 170% increase in the number of its customers.

Hutchison Whampoa, the parent company of 3 mobile, has released the above data. The company also said that 3 has seen an increase in its revenues in the half year ending on June 30. This has brought the half yearly revenue of the company to £784 million. While the increase in its revenue has been only 2%, it is much better than other companies which have suffered declines. O2 is the only other company to have registered an increase in revenues. T- Mobile, for instance, has seen a drop of more than 4% as compared to its sales in the previous year.

However, all is not well yet, as the average revenue per customer has been going down. The chairman of Hutchison Whampoa believes that this is due to price competition. He said rates for roaming and termination charges have come down, which has caused further reduction in revenue. The growth in subscriber base for 3’s mobile broadband service has also ironically become a drag on the company’s revenues.

New BT Regulations Cause Unrest among Customers

Filed under: Buyers + Consumers, Life Of Telecommunication, School of Technology — admin at 7:15 am on Monday, July 20, 2009

An Edinburgh based PC Pro reader recently got in touch with the magazine after finding out that BT had increased its cease fee to £25 from the earlier £18.11. According to the reader, BT had not promoted this fact actively to its users who were mostly still unaware of the charge hike.

As per BT’s new rules and regulations, even if the customers have seen through their minimum contract period, they will have to adhere to the new procedure. The new procedure states that whenever existing users plan to end their broadband services, they must request a migration authorisation code (MAC) to change their service provider. If they fail to do so, a fee of £25.00 will be charged. BT put this to effect from 12 June 2009 and the only escape from this charge is if the user moves to an address where the services of BT are not available. Click on broadband deals for reviews and price data for all the leading broadband service providers.

A BT spokesperson clarified that this charge was to act as a reminder for customers to persuade them to follow the right migration procedures and cover the expenditure that the company incurred due to technical aspects.

BT also said that the charge that they were levying on their customers was the actual cost that it incurred in case of termination of services, in terms of retrieving equipment or altering their records.

Survey Shows T-Mobile is Still the Best

Filed under: Buyers + Consumers, Life Of Telecommunication, School of Technology — admin at 8:45 am on Friday, June 12, 2009

The results of a mobile broadband service provider survey conducted by independent testing house, P3 Solutions are in, and the winner is, not surprisingly, T-Mobile. The study was also sponsored by the same company and this is the third consecutive quarter in which T-Mobile has emerged on top.

The company scored well in many areas which are part and parcel of internet usage, such as the speed of web browsing, email sending and receiving, downloads, and overall reliability. Even upload speeds were 44% higher than that of its nearest rival. The survey also used applications which are popular among customers to check the quality of service provided. Click mobile broadband best offers for reviews and price data for all the leading broadband service providers.

Commenting on the results, chief technology officer at T-Mobile UK, Emin Gurdenli, said that the company was only reaping the rewards of a sound business strategy as customers of T-Mobile services were beneficiaries of good network coverage and reliable company support. This is supported by the fact that T-Mobile has seen an escalation in the number of subscribers to its services, which has contributed to a 300% increase in the flow of internet data traffic through its network since late 2007.

An earlier independent YouGov survey also agrees with the findings of P3 on mobile network operators, as it had shown T-Mobile to be the best in 6 out of 13 categories. Most significantly the provider had come out on top in terms of coverage and customer support.

Manchester City Council to Begin FTTP Installation

Filed under: Buyers + Consumers, Life Of Telecommunication, School of Technology — admin at 7:41 am on Tuesday, March 24, 2009

The city of Manchester will soon enjoy a major broadband speed upgrade. The Manchester city council has declared that the Fibre to the Premises or FTTP broadband network that was under planning for one year is now ready to be installed. Work is scheduled to begin at the end of this month with the Oxford Road area in Manchester.

Even though claims are being made about the service being up to 1,000 times faster than current services, it probably will not be. A look at other such networks from around the world shows that actual speeds will not be more than 100Mbps, which will be about 50 times faster than the 2Mb speed that most people currently get.

Councillor Neil Swannick said that this is what a modern city needs for rapid economic development - a lightning fast and affordable broadband connection. According to him, it will do good things to the economy because businesses and other users need an extremely fast and reliable connection. He enthused about the possibilities of the advanced fixed line network and harnessing the potential of wireless broadband connections.

However, Mr. Swannick did agree that other European cities had it better than people in the UK. Cities like Amsterdam and Paris are providing fibre optic and other kinds of fast broadband connections to homes and business at rates that are much lower than here.

According to the action plan of the council, the foundations of the new network would be laid in first and the focus would then shift to expanding the area covered. The expansion would start with the development of a new Internet Hub in the Central Park area, with simultaneous work happening in the East Manchester Area.

Free Laptop with Broadband

Filed under: Buyers + Consumers, Life Of Telecommunication, School of Technology — admin at 8:58 am on Monday, December 1, 2008

A person really is spoilt for choice now with all the laptop for free deals around at the moment. All the mobile internet service providers are coming out with “free laptops” this and “free laptop” that, it’s enough to make your head spin.

The Samsung NC10 Netbook is the latest edition to the range of free laptops offered with mobile broadband. Now I’m not very tall, what I would say is petite, but what some might call short; so I’m happy to wave a flag for the smaller things in life. For those of us who like our laptops small but perfectly formed, this is one mini laptop that stands out for me. Its simple design features partnered with some impressive specs make this laptop one of the most enticing for me. For such a small device it comes loaded with a massive 160GB hard disk storage, 1GB of memory and an impressive 7.5 hours battery life.

So I’ve narrowed down my search for a free laptop with broadband deal, this is certainly one of the most appealing. You can get the Samsung NC10 Netbook free with a USB modem when you subscribe to a mobile broadband deal from a UK mobile internet provider.

Where Will VoIP Go from Here?

Filed under: Life Of Telecommunication, School of Technology — admin at 9:55 pm on Friday, October 3, 2008

It seems that nothing can stop the ongoing development of VoIP. Driven by lower cost faster internet connections VoIP has become one of the fastest-growing applications on the web. But apart from cheap calls, there are other factors which have contributed to this success story. There is clearly a trend toward more innovative and more mobile services and this looks likely to ensure that demand for Voice over IP continues to increase. It is estimated that there are already around four million VoIP users in the UK, not counting business subscriptions.
Key figures in the industry point to the advent of ADSL broadband connections that do not require line rental for a standard phone line (naked ADSL), and number portability between conventional and IP phone services as the two key things that will bring raise the profile of VoIP to new levels.

In fact such has been the impact of VoIP that some have suggested that it may not be long before users can dispense with their traditional landline telephones completely in favour of a internet phone.

Taking a more practical view, there are problems that will need to be addressed before that can happen. In the UK Internet telephony providers like Vonage or VoIPTalk will have to look closely at both security and ease of use, as well as continue to deliver a convenient and financially viable service. They certainly offer cheap calls already but, what else do they need to do to ensure a bright future for VoIP?
As the Internet is a huge public space the VoIP traffic is no more immune from attack than any other data. Security is a worry for many users, particularly in the business community and the means to increase protection for users would be a welcome step in securing the long-term future of VoIP.

The ease of use issue may not remain a hindrance to progress now that handsets that work on mobile networks and, via WiFi or Bluetooth links, over VoIP are now making an appearance in the shops. This raises the prospect of using low-cost VoIP services at home, in the office or at a WiFi hotspot, but still retaining the flexibility of mobile coverage when out and about.

Some VoIP providers are now selling these handsets, and have set up joint arrangements with wireless hotspots so that their subscribers can make and receive calls in public places without the need for a computer.

It’s likely that some of the restrictions of such handsets i.e. difficulties in hotspots that use web pages for authentication to be addressed any time now.

The advance of newer networking technologies will further decrease the gap between fixed, mobile and VoIP services. Wireless broadband services, in particular WiMax, could create city-wide wireless hotspots, making it possible to make mobile VoIP calls in much wider areas.

Increased Gaming Laptop Saturation Good for Customers

Filed under: School of Technology — admin at 1:35 am on Wednesday, August 13, 2008

Until recently, gaming laptops were normally built to order by boutique manufacturers. Regardless of the fact they weren’t good sellers they did have good mark ups. Everybody desired this kind of laptop, but at the price they were going for it was simply not affordable. They the the most revolutionary technology and basically the best laptops. Even though they did get everyone excited I don’t think they sold well because not many people actually buy laptops that are overpriced. As larger brands see the potential in the gaming notebook market, things appears to have shifted.

In my point of view they could get off by retailing them at a greater price if they desired. With notebooks becoming like consumer electronics this is a good profit source for them. They can also use their massive marketing spend to induce buyers further into spending their cash or getting out the charge cards to buy laptops like these ones. Could this be the downfall of the small retailers? Now customers will have greater options it makes it troublesome for the small retailers. I think the uneducated automatically feel safe by buying from a manufacturer they are aware of.

The buzz being generated regarding the new brand name gaming notebooks is making potential purchasers perceive them to be the best laptops in history. This will give some encouragement to the local system builders. Consumers like the service to customise because they can select what’s most important to them. Buyers of this sort are generally extremely educated in regards to the technology involved, and hence can carry out spec for spec comparisons. More often than not the specs hold more importance than the design for these kinds of buyers. All game players concur that its a favourable change. As this forces down the prices even further, new technology will become even more affordable to the customer. Things change so quick in this business that I can’t precisely produce any assured statements. I’m not sure if the overall price of notebooks will come down but new notebooks are normally at high prices. The well known brands have already launched their own gaming notebook range, so all we can do now is sit back and watch.

Transceivers: A Primer

Filed under: Life Of Telecommunication, School of Technology — admin at 6:08 pm on Thursday, July 24, 2008

Transceivers: A Primer

A transceiver serves two function; it is both a receiver and a transmitter which are combined together to form one unit and operate using the same circuitry. In some cases the circuitry will not be shared; in this case it is called a transmitter-receiver which was originally invented in the 1920s. Transceivers must combine a large portion of the handling circuitry that the transmitter and receiver share in order to be considered a transceiver and not a transmitter-receiver. If you are reading from an IEEE 802.3 document, then you will often see transceivers referred to as medium attachment units, or MAUs.

Medium attachment units can convert signals over either an Ethernet cable or an AUI signal. For the original 10base5 Ethernet, the medium attachment unit was often clamped directly to the Ethernet cable itself. Standards changed however with the advent of the 10base2. At this point the medium attachment unit was simply integrated within the card. Then in an effort to keep costs low, which was demanded by their consumer base, the entire Ethernet controller device was simply shrunken down into a single chip. Similar to a hub, a medium attachment unit shares much of the same characteristics, expect for the fact that an MAU allows a token to pass between the devices of different networks, even if the network utilizes physical Star topology. In modern Ethernet systems that are either hubbed or switch-based, the MAU and AUI devices are not used, except for in certain unordinary circumstances. They are replaced by the CAT5 cable. This cable connects directly into the Ethernet socket which can be found on the host or the router. Backwards capability exists with certain equipment which utilizes an external AUI interface. Medium attachment units can still be found on units with 10base2 and 10baseT connections.

Transceivers exist in various devices. They are most often used in computers, telephony, and radios. Computers often use transceivers in the guise of the previously discussed medium attachment units. These are often fiber-optic gigabit and 10 gigabit transceivers which are also known as: GBIC, SFP, XAUI, and XFP. Radio technology has made use of transceivers for a long time, although they will often be separate as transmitter-receivers. The Ham radio is a great example and they can be built using the operator’s own equipment. Finally, there is telephony, which uses transceivers via a wired phone or a headset. One such example is the common cellular phone which is, in itself, a transceiver.

Why The Frogs No Longer Sing - A Case Study on The Survival of A Freshwater Lake

Filed under: School of Technology — admin at 11:33 pm on Monday, June 9, 2008

I was disturbed to read today that the frogs from the Tasek Chini lake were no longer singing. They have practically disappeared. This may not seemed strange to you, in fact, you may not have any idea where Tasek Chini is. After all, it “was” a beautiful large mass of freshwater lake in the tropical forests of Malaysia. It “was” because it now no longer is beautiful as it was, with pollution levels reportedly 56 times higher than is considered healthy, and worse, this is right inside the tropical jungle.

The frogs are not the only ones disappearing. The fishes, cobras, pythons are also diminishing in numbers. Weeds called the “Cat’s Tail” have proliferated, snuffing out important sunlight that would allow organisms to grow.

This is worrying enough for some concrete action to be taken to revive the ecosystem. In retrospect, how can action be taken to protect the environment, or a delicate ecosystem such as Tasek Chini, or any other lake in the world?

Here at Tasek Chini I read about the Sustainable Development Network or SUSDEN which is running the Save Tasik Chini Campaign since August 2004, and these are remedial steps taken by the authorities and the Non Government organisations in concert to stop the decline:

1. Collect and remove fallen trees and weeds that choke the lake

2. reduce the pollution that comes from newly developed training camps for National Service that have been built near the lake

3. reduce the industrial pollution from nearby oil palm estates that bring fertilisers and pesticides into the lake

4. stop illegal logging activities near the lake

5. disallow opening of land within the forest near the lake

6. introducing programs to empower the aborigines called Jakun living in the surrounding areas of the lakes so that they continue to live there with their traditional resources that are linked to biodiversity conservation.

Most important of all is education to children on the importance of the lake and introduce them to the lifestyle of the aborgines living off the land surrounding the lake. These aborigines lived in harmony with the animals, plants and environment and they ensure the survival of the lake.

Now if you do have a lake in your area where you are living, ensure that the frogs still sing. Frogs are a good barometer of the environment. Frogs are declining due to habitat destruction, contamination, predation and genetic pollution. Will the frogs sing again at Tasek Cini? We do not know yet, but there is one thing we do know. Irregardless of where we are, if we save the frogs, we may be able to save our lives too.

Peter Lim is a Certified Financial Planner who loves the outdoors. Now, where it is not possible to go to enjoy the great outdoors and the lakes everyday, we can still enjoy the fresh air and scenery right in front of our own homes during summer with our patio chairs.
