  • IMPORTANT COMPUTER TERMINOLOGIES AT A GLANCE

    Virus, Spyware, Trojan, Worm, Malware

    These terms are often confused, although they have distinct meanings.

    A virus is a piece of software that can copy itself and which attaches itself to some other program in order to survive and replicate. It may have some malicious intent or it may exist simply to reproduce. A worm is similar but it can exist independently; it doesn’t need to attach to a separate program. A Trojan – or Trojan Horse – is a piece of software that gains access to a computer by pretending to be benign or by hiding within some innocent-looking application. The name is obviously derived from the wooden horse employed by the Greek army during the Trojan Wars. Spyware is software that secretly monitors computer activity, attempting to gain private information without the computer user knowing.

     

    By and large, all of the above will have some malicious intent – to harm data, spy on computer activity and so forth. Malware is a general term for all such programs – it simply means any software, of whatever sort, written with a malicious intent. Viruses are generally malware but there is more to malware than just viruses.

  • Sculptures of Gupta Period

    The Gupta period saw the mighty upsurge of national art. This period is popularly known as the Golden Age in the history of India. The famous Gupta emperors were Samudra Gupta who ruled in 325-375 CE, Chandragupta Vikramaditya 376 -413 CE, and Kumara Gupta 413 - 455 CE. Indian literature, religion, art and literature attained the great height of their glory. The Gupta art and culture not only spread to every nook and corner of India but also reached the Himalayan region and Central Asia. This cultural phase extended towards the south-east across the ocean into the islands of Indonesia or what was known at that time as Dvipantara. This cultural development was due to economic prosperity. This had a direct relation on the spirituality, which India had not seen before.

  • Cotton Industry UPSC

    The word "cotton" has Arabic origins, derived from the Arabic word qutn or qutun. Cotton is arguably the world's most important nonfood crop. It supplies about 80 percent of the world's natural fibers and continues to be primary material in half the world's textiles despite competition from synthetic fibers. Cotton is ideal for making cloth because its fibers bond and interlock when spun into long strands that can be is easily dyed.

    Cotton accounts for 40 percent of the fiber used today. About 20 million farmers in 80 countries produce 44 million metric tons of cotton a year. Cotton was rightly called white gold once.
