TERADATA

Teradata is a relational database management system (RDBMS) that is produced by the Teradata Corporation. Teradata database is fully scalable and Teradata database is mostly used in managing data warehousing projects. Teradata database management system uses symmetric multiprocessing technology along with communication networking to form huge parallel processing systems.

Teradata database management system is capable of accepting more concurrent requests from more than one client application. Few important features about teradata are full scalability, parallel efficiency, efficient load distribution and ability to execute complex queries framed using maximum of up to 256 joins.

Teradata database management system establishes data communication management with the help of components namely call level interface, open database connectivity, and teradata director program

What is GPS?

The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil and commercial users around the world. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver. The GPS project was developed in 1973 to overcome the limitations of previous navigation systems.

Bradford Parkinson, Roger L. Easton, and Ivan A. Getting are credited with inventing it. The design of GPS is based partly on similar ground-based radio-navigation systems, such as LORAN and the Decca Navigator, developed in the early 1940s and used by the British Royal Navy during World War II.

In addition to GPS, other systems are in use or under development. The Russian Global Navigation Satellite System (GLONASS) was developed contemporaneously with GPS, but suffered from incomplete coverage of the globe until the mid-2000s. There are also the planned European Union Galileo positioning system, India's Indian Regional Navigational Satellite System and Chinese Compass navigation system.


The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. GPS works in any weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or setup charges to use GPS.

The GPS satellite system

The 24 satellites that make up the GPS space segment are orbiting the earth about 12,000 miles above us. They are constantly moving, making two complete orbits in less than 24 hours. These satellites are travelling at speeds of roughly 7,000 miles an hour.

GPS satellites are powered by solar energy. They have backup batteries onboard to keep them running in the event of a solar eclipse, when there's no solar power. Small rocket boosters on each satellite keep them flying in the correct path.
Here are some other interesting facts about the GPS satellites (also called NAVSTAR, the official U.S. Department of Defense name for GPS):

• The first GPS satellite was launched in 1978.
• A full constellation of 24 satellites was achieved in 1994.
• Each satellite is built to last about 10 years. Replacements are constantly being built and launched into orbit.
• A GPS satellite weighs approximately 2,000 pounds and is about 17 feet across with the solar panels extended.
• Transmitter power is only 50 watts or less.

What's the signal?

GPS satellites transmit two low power radio signals, designated L1 and L2. Civilian GPS uses the L1 frequency of 1575.42 MHz in the UHF band. The signals travel by line of sight, meaning they will pass through clouds, glass and plastic but will not go through most solid objects such as buildings and mountains.

A GPS signal contains three different bits of information - a pseudorandom code, ephemeris data and almanac data. The pseudorandom code is simply an I.D. code that identifies which satellite is transmitting information. You can view this number on your Garmin GPS unit's satellite page, as it identifies which satellites it's receiving.

Ephemeris data, which is constantly transmitted by each satellite, contains important information about the status of the satellite (healthy or unhealthy), current date and time. This part of the signal is essential for determining a position.

The almanac data tells the GPS receiver where each GPS satellite should be at any time throughout the day. Each satellite transmits almanac data showing the orbital information for that satellite and for every other satellite in the system.

TRANSCEIVERS

A transceiver concerns the wide-ranging electronic products that are designed to act as a transmitter and receiver. They also share many circuitry components that are able to function when either transmitting or receiving. Transceivers appear in a variety of types which makes it possible to create a diverse range of merchandise.

Different Types of Transceivers

1. Walkie-talkie Radio
A simple product to incorporate the transceiver includes the two-way radio. A two-way radio comes in a choice of two configurations. This includes either the General Mobile Radio Service (GMRS) or Family Radio Service (FRS). The GMRS walkie-talkie is at the higher end of the scale and power rating. They can include up to 22 channels. The FRS is less powerful and operates with 14 channels (7 GMRS channels and 7 FRS channels). A walkie-talkie offers the ability to communicate between two hand-held devices within a set limit. The communication range can vary. This is often impacted by the number of obstructions that appear between the two hand-held units. A large open area (desserts, fields, plans, etc) with minimal line-of-sight obstructions is certain to offer a greater range compared to those attempting to use the two-way radios in built-up urban areas. Any walkie-talkie within a set range is able to pick up transmissions sent from another device using the same frequency channel.


2. Mobile Phones
A more complex type of transceiver includes the mobile phone. By relying on communication towers and satellites, the mobile phone is capable of sending and receiving data at higher speeds and across greater distance compared to the walkie-talkie radios. They are also able to send and receive data in several different ways. This can relate to streaming data over the internet, multimedia messages (video and photo) and text messages.


3. Rescue Devices
Beyond the standard communication devices, the transceivers are able to help create many other types of devices. A common type of product relates to the search aids, such as the avalanche transceiver. This is highly beneficial for helping those who get caught up in difficulties on the mountains. A device like this is attached to the body to make sure it provides a direct signal to the person experiencing the problems. Each rescue device has two modes, which includes a trigger for receiving and sending an electronic signal. When a person is out on an avalanche-prone area, the rescue device is worn and set to the send mode. A rescuer also has access to a transceiver in receive mode, which makes it possible to find the distressed person.

Facts About Email

•        160 billion emails are sent daily, 97% of them are spam.

•        Ray Tomlinson was first person to hit send on a network e-mail message.

•        It was also his idea to use the @ sign to separate the name of the user from            the name of the computer.

•        “123456″ is the all-time most popular choice for protecting our precious                  online correspondence.

•        Spammer get 1 response to every 12 million emails they send (yet it still                makes them a small profit).

•        Queen Elizabeth of Britain sent her first email in 1976.

•        Some 190 billion emails are sent daily – more than 2 million per second – by           1,2 billion email senders.

•        About 70% (133 billion emails) are spam and viruses.
