MRAM will lead to the instant switching on and off of computers as fast as a light switch. IBM is going to present its high speed 128 K bit MRAM core. The interesting fact of this MRAM is that it is fabricated with 0.18 micron logic based process technology. This feature enabled IBM to make the smallest size of MRAM.

Just imagine the size of the MRAM is about 1.4 square microns this size is 20 million times smaller than the average pencil eraser top. You will wonder that how such a small size will be unable too store memory. This problem is over come by accurately patterning the magnetic structure within this small cell. This enables the MRAM to control, memory reading and writing operations.

MRAM uses magnetic charges to store information rather than the electronic signals. So it is able to store more data. It is undoubted that MRAM will significantly improve the portable computing products. This will happen in the following ways they will store data faster, access the data faster and use less battery power obviously.

The combinations which this MRAM has are as follows low cost of Dynamic RAM [DRAM], High speed of static RAM [SRAM] and importantly the non volatility of flash memory. The most important advantage of MRAM is that it retains information even when the power is turned off. This enables the Personal Computer to start immediately without the waiting for soft ware to “Boot Up”.

MRAM will be the universal technology of the future it will alter the entire memory market in few years time. MRAM has nonvolatile memory technology lifestyle solutions. This application will save power as well as time. Since after shutting of the computer MRAM will directly take the users to the settings which they have left. So computers will be able to function like television or radio in that respect only. [tags] The features of RAM of IBM, Current changes in RAM, About MRAM [/tags]

Troubleshooting is actually the form of solving a problem in your system. It involves systematical scanning of your computer and the n finding a solution for the problem.

The following article gives information about the Troubleshooting software for IBM ThinkPad.

Troubleshooting the Windows media player 10 on your ThinkPad.

One of the most common problems is related to the codec. The codec is software that is used in the process of the compression and the decompression of a file that is run on the windows media player. For e.g. a song or a video. The creators of the data use the codec because the compressed data occupies less space. The compressed file can be transferred more economically and smoothly. The windows media player on your ThinkPad uses the codec in order to decompress the data and play it.

The codec is made up of two parts namely the encoder and the decoder. The encoder compresses the data during its manufacture, and the decoder decompresses the data so that it can be played on the Windows media player. However the genuine problem in the working is that some codecs include only one part of the components. When you install a DVD playback on your ThinkPad the program most probably will, install a codec that includes a MPEG 2 decoder. Due to this the DVD is played in the ThinkPad however you would not be able to create your own DVD using the decoder.

If you wish to find the appropriate codec for a given piece of data, the most convenient web site that you can use is the WMPlugins.com. In case of the ThinkPad’s it another web site that is recommended is the Microsoft.com. However there is a possibility that codec that you are looking for is non compatible with the windows media player, hence you will not be use the player for that specific piece of data.

In order to protect your ThinkPad do not use the codec the is not listed on the WMplugins.com and the Microsoft.com.

In case you want to troubleshoot any other system on your ThinkPad you can always consult the reputed sites on the web.

Processing Speed settings

The processing speed of PC300 of type 6563, 6564, 6574, and Aptiva type 2178/2198 computers are fixed and its speed is depend upon processor ‘s speed.

Working

We know that the speed of computer depends upon the speed of processor and the speed of chipsets of motherboard determine the flow of information between devices

The speed of RAM which is connected to the processor determines how fast the computer responds to the programs and therefore it has very important effects on memory. The general rule of is that the more RAM the computer has, the more.

Speed we will get.

Much of memory is available in the form of dual data rate which is also called DDR rate this also means that it will doubled the transfer rate of data between devices which make memory much more faster.

There are other computer video connectors that you may find on your laptop. Most of these can be adapted with the VGA cable in the room. One of these is DVI that sends the video in digital form from the computer to the display. Most laptops with a DVI port supports analog over DVI or DVI-I to use an economical adapter to convert this port to VGA.

Now, IBM has provided VGA connection on its laptops. Hence, here information about how to install and use this feature is given. The order in which you do things with computers and projectors is very important. When turned on, some laptops examine all the ports and connectors to see what’s hooked up. If the projector is not connected during startup, the laptop may not activate the external video connector. Hence, it is advised to follow the following steps.

1) First you have to physically connect the two devices using a standard VGA cable. Some laptops like the Sony Vaio, the Apple iBook and new G4 Powerbooks do not have VGA monitor connectors. You have to make sure that you have the adapters or docking ports with you that are needed to connect to a VGA cable.

2) Then, turn on the projector, allow it to warm up and choose the proper computer input using the projector’s remote control.

3) Then, you have to turn on your computer. It is recommended to have your AC power adapter for your laptop and keep it plugged in during the presentation or else, the laptop may go into sleep mode during your presentation.

4) The last step is to set your laptop to the proper resolution. Most projectors will range almost any resolution to fit the screen, but the image clarity will be best when the projector is at its native resolution.

They contain the polarizing sheets and the cells of the liquid crystal, which is a matrix of a thin film transistor for making a TFT LCD. With these devices, you can store the electrical state of each of the pixels, while the other pixel’s updating is going on. As result of using this method, we can get a very bright and sharper display than we would have got with the help of the passive matrix of the similar size. Nevertheless, the most important feature of these screens is the viewing angle.

The manufacturers manufacture them from the film transistors. In addition to this, the other components the manufacturers user are the diodes. As in the transistors, during the switching action, the desired pixel receives charges and it acts like the capacitor for holding the charge, until the next refresh cycle begins. The active matrix technology has an improved image quality over the passive matrix. In active matrix, technology there is an array of simple LCD cells. One cell per monochrome pixel is present and generally, there is a one thin film transistor for each cell. By applying the proper voltage to the select line that connects the TFT gates of that row, you can select a row of pixels. On the selection of a row of pixels, we can apply a voltage that we desire. You must ensure that you apply the voltage is applied only to the selected pixel. The TFT is an array of ideal switches.

There are a number of active matrix displays, which are available in the market. Each of them has a characteristic physical display resolution. These signify the number of the dots and the pixels that are present on the entire screen. For more resolution, higher number of dots must be present on the screen. The total number of dots that a screen has is the same for all the types. For example, the QVGA has a resolution of 320 X 240.
