Hard disk is the important storage device of computer. It cannot be replaced by a semiconductor storage device like a semiconductor memory such as the pen drives that we use today. This is because the dynamic locating of memory on semiconductor is not possible. Sequential memory allocation is the only possible way to access semiconductor memory. But in case of a magnetical storage device like hard disk it can be accessed dynamically by moving the read/write head to the corresponding position. But one problem seriously affecting the magnetical storage devices is that the data storing capacity cannot be made so large. Researches for developing larger sized hard disks are going on different multinational industries like IBM, Motorola etc.
I am going to tell about one outcome of these researches made by IBM. This new technology can be named as Pixel Dust. In the last five years hard disk capacity has been doubled by the use of double layered disks. But according to the IBM this new technology will push back that limit. IBM is planning to revolutionize the hard disk production by the use of this new technology. For users this new data density will give a transition of home entertainment from analog to the digital interactive formats.
When telling about the new technology it is a modification of the hard disk material that we use for data storage. The new material called the ruthenium is used for this purpose. This metal is precious like platinum. This metal will be sandwiched between two magnetic layers. This new material is expected to store data of about one million bits per square inch of the disk. That means 100 GB of data can be stored in one square inch. Current hard disk is capable of storing about 20 GB of data per square inch. This new method will quadruple the storage capacity.
Technically this anti ferromagnetically coupled (AFC) or pixel dust technology will be powering the hard disk in the future. The advantage of using this type of hard disks is that it can handle large amount of data with less power. As the size of drives increases the problem affecting the data read and write is that it can corrupt the data present in the drives. In order to avoid this Super paramagnetic (SPE) effect has to be used. Also these will enables faster data read and write in the hard disks. Another advantage of using this AFC media for data storage is that the life AFC media is more than current hard disks that we use now.
Our communication field has developed to an extent that we can access Internet on our mobile phones. But the technology used for this is GPRS/EDGE. The new technology called the third generation or 3G will be providing faster Internet when compared to GPRS or EDGE. 3G technology came into existence in the near days. The next footstep of communication field will be to provide Wi-Fi access for mobile phones. For this the mobile towers is to be provided with the necessary devices for Wi-Fi communication and also to use it the mobile phones should have Wi-Fi access and necessary protocols.
Wi-Fi has different modes of communication based on their speed and range of propagation. New methods are developing by the researchers for getting larger distance of communication for the Wi-Fi. In this article I am going to mention about one such footstep. This new technology is called Wi-max or 4G. According to IEEE this new service is named as 802.16. This technology will be providing wireless access of Internet in the Metropolitan cities in the future. This technology can provide a range of 50 km for fixed stations and 15 km for mobile terminals.
In the future Wi-max will find application in almost many of the fields like traffic, medical, weather and many more.
Smart Grid in power distribution
With smarter ways of power consumption we can avoid the energy wastage and unwanted use. By the use of Wi-max technology the rapid analysis and checking of power usage helps to track the household and industrial consumption of electricity and we can adjust the energy production to meet the necessity. Also if there is unwanted wastage of energy the consumer can be alerted to stop that.
TV Broadcasts
In the future the TV broadcasting towers will be replaced by the Wi-max transmission methods. With this new technology live broadcast of TV programmes will be possible in a faster rate than that we use now. A simple device attached to the camera is the only device needed for this technology. It will link the camera to the broadcasting antenna and the broadcasting satellite. Transmission takes place in real time and can be accessed and processed in the studio with satellite receivers and dishes.
Video tracking
This technology will provide video tracking of the streets and localities and will help to monitor the situations of important places. Moreover that it can be used for security purposes and it can be accessed remotely by the officials. Efficient traffic monitoring and control is possible with this technology. The density of traffic can be monitored and signals can be automated based on this.
Safer driving using Wi-max
The transportation system will become intelligent upon the implementation of Wi-max. The driver will be alerted about the traffic situations and blocks in their route and they can decide their path of journey. The advantage of Wi-max is that since it is wireless there is no difficulty for the driver to access it. He can operate his device from anywhere there is a Wi-max hotspot like in W-Fi. Indirectly it will ease the traffic management for the traffic control officers.
Tracking of routes
Like GPS tracking devices Wi-max will also provide an option for tracking of routes in a region. One of the advantages when compared to the GPS is that the tracking by using Wi-max will be real time and it will be more efficient than GPS.
Medical Field
In medical field wireless technology is widely using for various operations like patient monitoring etc. With the introduction of Wi-max this will become more efficient than the previous systems. For example if a person suffering from Hypertension is to be monitored then a sensor attached to his blood vessel will monitor the pressure and will inform the doctors when the pressure goes below or rise.
Reminder Services
With Wi-max we can set reminders for taking medicine or drugs on particular time. If the patient doesn’t opens the bottle of drug the sensor attached to the bottle will monitor this and will inform the patient to take the drug. This will be very helpful for those who don’t have enough time to spend for remembering this in his busy daily activities.
SEO is an signifier for "Search Engine Optimization" is Technology based on the process of enhancing the volume or increasing the quality of traffic heading towards a particular website from search engines via "natural" or un-paid search results as contradicted to search engine marketing (SEM) technology dealing with cellular inclusion. Typically, the earlier (or higher) a site appears in the search results list, it increases the chances of visiting it's site by more users. The SEO studies the technology behind the working of search engines and what the users are searching repeatedly.
SEO is an industry of advisers which analyze the technology of carrying out optimization projects on place of clients,and by employees that do SEO services from their homes. These days technology has changed and also the client's interests have deviated towards Google, Yahoo, AOL and MSN. This restricts many database we have to work with. Thus,differentiating the technology and making the SEO work a bit difficult and frustrating too.
Earlier it was not very difficult to upgrade your rank unlike today. Also, the clients have become much more particular while demanding new technology for SEO as they are exhausted now and don't wish to spend huge money anymore on PPC ad campaigns. undoubtedly, the client expectations will tend to degrade in the coming years. The technology for optimizing for longer phrases, there's a good chance you're going to have to buy them through ads. The exiting news is that prior to the difficulty in attaining high ranking, a lot many SEOs are also concentrating on other technology aspects like clients' Web sites.
The reasons for adopting this technology deviation is twofold. Firstly, despite og gaining higher ranks due to extremely competitive keywords that deviate tons of targeted traffic, if your Web sites sucks, you will fail in making any money. Secondly, when your are required to focus on less general phrases, it forces you to really take a hard look at your site, and make sure it's truly working for you. Keeping this aspect aside, a dim future for traditional SEO in many senses can be visioned. The Reason, Degradation in technology. Some years back, only some of the Web sites had even a fundamental bit of optimization done to them. This technology used to facilitate any one having only little SEO knowledge, even in triangle amount to come in and obtain some decent results.
There are hundreds of stories about ambitious people who quit their job to start business in their garages, worked 80-hours weeks, sold their companies and wound up rich. This isn't of them. Instead, this is about the growing number of average people who are spending their leisure hours selling hobbies and services on home computers and the internet. With full-time salaries stretched thin and the cost of necessities rising, more people are looking for low-risk to earn extra income.
"The Web is a great place to shop and spend money, but it's pretty great for making money too," says Joanne Pratt, a Dallas-based adviser to the Small Business Administration on at-home commerce. More than half of all small businesses are based at home, according to the SBA. "Computers, Internet access, cell-phone technology and simplified web-page design software have all become cheaper and faster in recent years, making it easier to lunch some type of at-home enterprise without sinking a lot of money into it," says Simon Yates, senior analyst at Forrester Research. Most people who run at home businesses use a laptop computer, connect to the internet and live in a household where the average annual income is $65000, reports Forrester.
To manage the extra cash, many entrepreneurs are using accounting software programs for small businesses, such as Intuit's QuickBooks line, which generated revenue of $654 million last year--a jump of nearly 100 percent since 2000. "If you're the slightest bit entrepreneurial, you can reach large numbers of consumers instantly over the internet, while keywords searches at Google let consumers reach you just as quickly," says Pratt. "The Web is an amazing marketplace." How can you turn your PC into a cash money ?
