Text 1. Modern Computer Technology

Technology is not only the light of the darkness way of our life but also the solution key of any problems and the improvement of our success. The touch of technology in the computer field is the surprising invention beyond our thinking. Today's gift of the technology is amazing to us and it will be backdated tomorrow for the exponential improvement of technology. Computer technology is not only being improved by the year to year but also improving day to day and for that reason the real invention of present was limited in thinking in the yesterday and today's imagination will also be real tomorrow. As computer is formed by the synchronized accumulation of its two fields like hardware and software, the technology is also keeping his contribution significantly in these two fields for also making the computer as the great performer.

With the advancement of computer technology the size of the computer is becoming smaller and more effective than the before. The data storage capability of the computer is now limited to the megabyte and usually it extends to the gigabyte to terabyte and in this way modern computer is the world within a world. Hard disc, DVD discs and removal discs are such kinds of memory storage device those are now small in size and more capable than the before.

Instructions executor of computer are known as the computer processor which is more powerful now because of the invention of modern technology. Modern computer technology has now combined two, four, eight or more core in a single processor to get the extreme performance and these kinds of processor are known as the dual core, core-2-dua, core-2-quad and core-2-extreme in the market. These types of processor are 2, 4, 8 and even 16 times fasted to process data. The cash memory and the bus speed are also not limited to the kilobyte and it is extended to the megabyte now. With these basic elements, the other component of the computer is becoming greater performer and effective those were only in imagination a few days ago.

The period has gone away to use bulky part and overweighed tools for the setup of your computer. LCD monitor has solved these kinds of problems and it is comfortable to our eye for the filter technology that filters the harmful ray emitting from the monitor. The most advantageous gift of the modern computer technology is the laptop computer which is small in size and flexible to use it. The producer of this product have also tried to accumulate the advantages of the modern technology like Bluetooth, web came and such as such.

The modern processor, monitor and the overall computer are low power consuming and more effective. The RAM of the computer is the helper of processor which is used as the primary memory for analyzing code instruction or software and the memory size of RAM now exceeds to single gigabyte. Software, usually open source software are being improved too rapidly which give us the new features day by day. Popular and user friendly operating system like Windows operating system is updating with great features to satisfy the requirements of the users. Open source software and operating system like Linux give you the update time to time and you can add features as you like. For these great features computer is said to be the wonder of science and modern computer technology is the successor of that wonders.

Text 2 How Does Mobile Wireless Broadband Work?

Access

Mobile wireless broadband is a form of broadband that uses radio waves to set up a wireless networking area. Unlike wireless broadband which can set up in the home, mobile wireless broadband tends to mean the private and public service found outside the home. Accessing mobile wireless broadband services from Internet cafes, parks, airports and hotels usually requires a service provider have a tower nearby.

Broadband Technology

Mobile wireless broadband technology lets users access the Internet via radio waves emitted from a tower. Service providers use these to service the area within the tower’s limit, sometimes only 100 meters. Building them in every neighborhood and apartment complex would allow anyone to access them, but this would be too costly. This limit is why towers are more commonly found in hot spots like airports and parks.

In order for a laptop or computing device to access mobile wireless broadband, a wireless networking card or USB device must be plugged into the laptop or device. Most laptops have internal wireless capability. Some networks require an access fee, while others can be public and free. Wi-Fi is a form of networking that uses short-range radio waves, accessed via base towers.

3G Technology

In Australia, 3G mobile wireless broadband uses 3G mobile phone services to provide Internet access. These networks are being installed and have ranges up to 10 kilometers and more. It uses a licensed part of the electromagnet spectrum usually for mobile phones. These vast ranges of communication allow wider coverage, but also give advantages to users operating from moving services, like trains and buses.

WiMAX is another type of mobile wireless broadband that has ranges able to compete with 3G technology. In Australia, the service is available only in major cities. The problems facing WiMAX include licensing parts of the electromagnetic spectrum and competing against other global telecommunications.

In China, 3G wireless broadband is run by China Telecom, which opened its first 3G services in Beijing in April 2009. The ability to transfer data like videos, movies and music at high speeds attracted more than 10,000 customers before the service even launched. Any customers in range of Beijing Telecom’s broadcasting towers can access the wireless broadband network. In China, 3G mobile wireless broadband has a greater audience than the 3G mobile phone services set to launch in May of 2009.
