Increase your RAM and so system speed

Increase your RAM and so system speed


1). Start any application, say Word. Open some large documents.


2). Press CTRL+SHIFT+ESC to open Windows Task Manager and click Processes tab and sort the list in descending order on Mem Usage. You will notice that WINWORD.EXE will be somewhere at the top, using multiple MBs of memory.


3). Now switch to Word and simply minimize it. (Don't use the Minimize All Windows option of the task bar).



4). Now go back to the Windows Task Manager and see where WINWORD.EXE is listed. Most probably you will not find it at the top. You will typically have to scroll to the bottom of the list to find Word. Now check out the amount of RAM it is using. Surprised? The memory utilization has reduced by a huge amount

5). Minimize each application that you are currently not working on by clicking on the Minimize button & you can increase the amount of available RAM by a substantial margin. Depending upon the number and type of applications you use together, the difference can be as much as 50 percent of extra RAM.



In any multitasking system, minimizing an application means that it won't be utilized by the user right now. Therefore, the OS automatically makes the application use virtual memory & keeps bare minimum amounts of the code in physical RAM.

Myspace Facts

MySpace was founded by former Friendster members Chris Dewolfe and Tom Anderson in 2003. They saw opportunity to beat Friendster with more options and less restrictions for social network users. MySpace was purchased in 2005 for $580 million by Rupert Murdoch creator of a media empire that includes 20th Century Fox and the Fox television stations. MySpace has more than 40 billion page views a month. Google paid $900 million to be MySpace's search provider. MySpace runs on Microsoft .NET Framework, operating under Windows 2003 server and applications written in C# for ASP.NET.

History of Amazon.com
Jeff Bezon coined the term Amazon.com from the earlier name Cadabra.com. It was the excellent way to present large volume online bookstore. But did he have hidden intentions? It is hard to believe but in the early Internet days, when Yahoo was dominant search engine, results on one page were listed alphabetically. Amazon would always appear above its competition for a specific keywords. This could be a breaking point for Jeff to expand and became what it is today.

What Is Google?
Google, the Internet search company founded in September 1998. by Larry Page & Sergey Brin, got it's name from the word Googol, which represents number 1 followed with hundred zeros after it.

What Is Yahoo!?
Yahoo the complex internet organism has complicated name. Word "Yahoo" is shortcut for "Yet Another Hierarchical Officious Oracle". It was coined by PhD candidates at Stanford University: David Filo and Jerry Yang.

Differences of GSM, GPRS, UMTS and HSDPA

Differences of GSM, GPRS, UMTS and HSDPA <====
1. GSM: 2G Europian standard and the first digital mobile system. It offers only
circuit-switched traffic (i.e voice calls,
SMS...etc) and data transfer at very low
bitrates 9.6kbps.

2. GPRS: also reffered to as phase 2+. It offered packet-switched traffic with
new network components integrated
over the existant GSM core network.
This allowed data bitrates to increase
to 171kbps. It is also considered as the
first step towards 3G networks.

3. EDGE: It was made to cover the delay of delivery of 3G/UMTS network.
It supported data rates upto 384kbps.

4. UMTS: the first 3G Europian standard network. It is the optimal solution for
GSM operators to support 3G services.
The Air interface technique used for
this network is WCDMA. This technique
allowed data rates to reach 2Mbps.

5. HSDPA: It is actually a software upgrade to the UMTS network using
the same air interface technique used
in UMTS (WCDMA) and supporting data
rates upto 10Mbps.

Q: Why is my internet connection intermittent despite full HSDPA signal?
A: The service that you receive on your connection depends partly on how
busy the network is. Voice and text
users take priority over dongle (data)
users, so when the network is
particularly busy, data speeds may be
slow even though signal strength is high. Conversely when the network is
not busy, you may get fast data speeds
although you barely have a signal.
Unfortunately you can only influence
this aspect of service by connecting at
less sociable hours

Mobile phone tracking

Mobile phone tracking tracks the current position of a mobile phone even on the move. To locate the phone, it must emit at least the roaming signal to contact the next nearby antenna tower, but the process does not require an active call. GSM localisation is then done by multilateration based on the signal strength to nearby antenna masts
Mobile positioning, i.e. location based service that discloses the actual coordinates of a mobile phone bearer, is a technology used by telecommunication companies to approximate where a mobile phone, and thereby also its user (bearer), temporarily resides. The more properly applied term locating refers to the purpose rather than a positioning process. Such service is offered as an option of the class of location-based services (LBS).
Technology

The technology of locating is based on measuring power levels and antenna patterns and uses the concept that a mobile phone always communicates wirelessly with one of the closest base stations, so if you know which base station the phone communicates with, you know that the phone is close to the respective base station.

Advanced systems determine the sector in which the mobile phone resides and roughly estimate also the distance to the base station. Further approximation can be done by interpolating signals between adjacent antenna towers. Qualified services may achieve a precision of down to 50 meters in urban areas where mobile traffic and density of antenna towers (base stations) is sufficiently high. Rural and desolate areas may see miles between base stations and therefore determine locations less precisely.

GSM localization is the use of multilateration to determine the location of GSM mobile phones, usually with the intent to locate the user .

Localization-Based Systems can be broadly divided into:
Network based
Handset based
Hybrid

Network Based

Network-based techniques utilize the service provider's network infrastructure to identify the location of the handset. The advantage of network-based techniques (from mobile operator's point of view) is that they can be implemented non-intrusively, without affecting the handsets.

The accuracy of network-based techniques varies, with cell identification as the least accurate and triangulation as the most accurate. The accuracy of network-based techniques is closely dependent on the concentration of base station cells, with urban environments achieving the highest possible accuracy.

One of the key challenges of network-based techniques is the requirement to work closely with the service provider, as it entails the installation of hardware and software within the operator's infrastructure. Often, a legislative framework, such as E911, would need to be in place to compel the cooperation of the service provider as well as to safeguard the privacy of the information.

Handset Based

Handset-based technology requires the installation of client software on the handset to determine its location. This technique determines the location of the handset by computing its location by cell identification, signal strengths of the home and neighboring cells or the latitude and longitude, if the handset is equipped with a GPS module. The calculated location is then sent from the handset to a location server.

The key disadvantage of this technique (from mobile operator's point of view) is the necessity of installing software on the handset. It requires the active cooperation of the mobile subscriber as well as software that must be able to handle the different operating systems of the handsets. Typically, smart phones, such as one based on Symbian,Windows Mobile, iPhone / iPhone OS, or Android, would be able to run such software.

One proposed work-around is the installation of embedded hardware or software on the handset by the manufacturers. This avenue has not made significant headway, due to the difficulty of convincing different manufacturers to cooperate on a common mechanism and to address the cost issue. Another difficulty would be to address the issue of foreign handsets that are roaming in the network.

Well, let us find an example to demonstrate the Network based location tracking algorithm: According to global GSM structure and ETSI, the GSM service providers information flows through the control channel and the control channel is free to access. Interestingly, all the present GSM modem/mobiles (Telit, SIMCOM, HTC, Nokia etc.) are coming with some extra feature to monitor the neighbouring cells and its RSSI value. Theoretically you should get 1+6=7 cell information (1 home cell ID, 7 BCCH info+ 7 RSSI). If you know the location of 7 cells, it is possible to get a mobile phone location with very high accuracy (<100 meters).

hybrid

Hybrid positioning systems use a combination of network-based and handset-based technologies for location determination. One example would be Assisted GPS, which uses both GPS and network information to compute the location. Hybrid-based techniques give the best accuracy of the three but inherit the limitations and challenges of network-based and handset-based technologies.

Examples of LBS technologies
Cell Identification - The accuracy of this method can be as good as a few hundred meters in urban areas, but as poor as 35 km[4] in suburban areas and rural zones. The accuracy depends on the known range of the particular network base station serving the handset at the time of positioning.
Enhanced Cell Identification - With this method, one can get a precision similar to Cell Identification, but for rural areas, with circular sectors of 550 meters.
U-TDOA - Uplink-Time difference of arrival - The network determines the time difference and therefore the distance from each base station to the mobile phone.
TOA - Time of arrival - Same as U-TDOA, but this technology uses the absolute time of arrival at a certain base station rather than the difference between two stations.
AOA - Angle of arrival - AOA mechanism locates the mobile phone at the point where the lines along the angles from each base station intersect.
E-OTD - E-OTD is similar to U-TDOA, but the position is estimated by the mobile phone, not by the base station. The precision of this method depends on the number of available LMUs in the networks, varying from 50 to 200 m.
Assisted-GPS - A largely GPS-based technology, which uses an operator-maintained ground station to correct for GPS errors caused by the atmosphere/topography. Assisted-GPS positioning technology typically falls back to cell-based positioning methods when indoors or in an urban canyon environment.
Hybrid - As mentioned above, hybrid positioning systems use different methods depending on which signals are locally available.
