Essay on Nanotechnology - 1050 Words

Nanotechnology is the engineering of functional systems on molecular scale. In its original sense, 'nanotechnology' has been interpreted for the INS AT fleet in the classroom, including 24 C-band transponders, six extended C-band transponders, two S-band broadcast satellite service transponders and mobile satellite service transponders. . Satellite beams commercial television signal to customers in India.

After this, an Ariane 5 rocket took the Indian-made satellite INSAT-3A from the Kuoru to the space on April 9, 2003. 3,000-lb The satellite took charge of communications, weather imaging and search-and-rescue wages. It measured 9 to 6.5 feet by 6 feet, while its solar panels were spread over 43 feet.

Resource-1 launched on October 17, 2003, was the tenth satellite of ISRO in the IRS series. Its purpose was to continue not only to provide remote sensing data services provided by the IRS-1C and IRS-1D, both of which addressed the life of their design mission, but also increased the quality of the data. Is of Its mission was five years of life.

GSAT-3, known as EDUSAT, was launched on September 20, 2004. As the first dedicated academic satellite, it provided two types of satellite based communications in the classroom room to distribute the country to satellite materials. This geo-synchronous satellite was developed on the bus of I-2 and was co-located with METSAT and INSAT-3C at 74 degrees east longitude.

Cartosh-1, the first class remote sensing satellite is capable of providing in-class stereo images, was launched on May 5, 2005. Images are used for cartographic applications that meet the global requirements. The camera of this satellite has a resolution of 2.5 meters and even a small car can make a difference. Provides necessary stereo pairs for generating digital height models, Ortho image products, and value-added products for various applications of Satellite Geographic Information System (GIS).

INSAT-4A provides services in the first series Q & C band frequency band in INSAT-4 satellites. Q transponders cover the Indian mainland while the C-band transponders cover an extended area. This space shuttle was placed on December 22, 2005 at 83 dog bay with INSAT-2E and INSAT-3B by Ariane Launch Vehicle (Aryan-5V169). The life of this satellite is estimated to be twelve years.

ISRO organized Space Capsule Recovery Experiment (SRE-1) to demonstrate the technique of a classroom platform to experiment in microbiology conditions. The SRE-1 mission provided a valuable experience in areas such as navigation, guidance and control during the re-entry phase, the development of hypersonic aero thermodynamic, reusable thermal protection system (TPS), through repetition.

The first Indian satellite to be placed in space was Aryabhata, which was held on April 19, 1975. After this, on October 7, 1979, Bhaskar-1, an Earth observation satellite was launched. Although these two satellites were launched outside India, India launched its satellite for the first time on July 18, 1980. This Rohini-1 satellite was high on the Satellite Launch Vehicle (SLV) rocket from the Sriharikota island launch site. Since then, India has invested a great deal of its space development work in complex app satellites.

India has two main interest satellites for remote sensing and communication. They are used for feeds for weather images, disaster warnings and on the ground 552 television and 164 radio stations. By the end of 1985, Rohini -3 communication satellite, which started in August 1983, increased television coverage across the country from 20 percent to 70 percent. Today it is about 90 percent.

One of the satellites in India's stretch Rohini Satellite Series, SROSS-C, was launched on 20th May 1992 on an increased Satellite Launch Vehicle (ASLV). It was India's first astrophysicist. 235-lb. A gamma ray blast detector made of high-voltage scintillation detectors centered on the southern sky in the satellite was the detector. Unfortunately, satellites fell from the orbit only after 55 days. The replacement was launched on SROSS-C2, May 4, 1994.

On April 18, 2001, one of the Geo-synchronous Satellite Launch Vehicle (GSLV) rockets of India, from Sriharikota Island Launch site, has 1.5 ton experimental communication satellite named GSAT-1 in the geological orbit of 22,300 miles away from Earth. GSAT-1 was a communications satellite with a digital satellite, data and video transmission, in which two S-band, one high power c-band and two indigenous C-band transponders were used.

On October 22, 2001, India launched its Technology Experiment Satellite (TES) on a Polar Satellite Launch Vehicle (PSLV-C3) from Sriharikota to a 350-mile-high grade. 2,440-lb. Satellite took a pancromatic camera for earth-imaging and tested new payload technologies ranging from communication to remote sensing. The satellite was monitored by ISRO's Spacecraft Control Center (SCC) Telemetry Tracking and Command Network (Istcrack) in Bangalore with its small network of tracking stations in Lucknow, Mauritius and Russia.

Indian National Satellite, ISRAT-3C, was designed and manufactured by ISRO on January 24, 2002 on a European space agency Aryan-4 rocket. Satellite added more communication capability using e-mail filters. Firewalls are programs that protect users from unauthorized access attacks on a network. They only provide access to known users, or users who allow.

The advent of multi-user systems depends on the security of the password. It is important that the password of sensitive data be kept safe. Therefore, not only do they need to change frequently, but they must be kept complicated enough. In addition, safe surfing should be followed by all users on the network. Keeping people in the email address private, not chatting on open systems, who do not have sufficient security methods, by visiting secure sites, accepting data from known users only, downloading carefully and being included only from known sites Includes.

Typically employed method for preventing cyber attack is the continuous detection of someone's computer for viruses and worms. In the form of floppy disks and CD-ROMs, any external media should always check the virus before running. For people using e-mail, they should employ e-mail filters, which monitor the flow of mail in the inbox and automatically remove any suspicious or useless mail, thus, the bombing Or reduce the chances of getting spoofed.

Due to the high speed at which the information highway is entering our homes, we are increasing the risk of all cyber crime being affected. Since everything about our lives is influenced by the computer, it is a long time that we understand that cyber crime is not only the problem of those people who use computers, but this is everybody's problem.
