Question: Denial of service attacks are designed to make a machine or network resource unavailable to its intended users. Attackers can deny service to individual victims, such as by deliberately entering a wrong password enough consecutive times to cause the victim account to be locked, or they may overload the capabilities of a machine or network and block all users at once. While a network attack from a single IP address can be blocked by adding a new firewall rule, many forms of Distributed denial of service (DDoS) attacks are possible, where the attack comes from a large number of points and defending is much more difficult. Such attacks can originate from the zombie computers of a botnet, but a range of other techniques are possible including reflection and amplification attacks, where innocent systems are fooled into sending traffic to the victim.

Answer: Distributed denial of service
Question: Throughout their history, the Liberals have been in electoral terms largely the party of the middle class (whom Menzies, in the era of the party's formation called "The forgotten people"), though such class-based voting patterns are no longer as clear as they once were. In the 1970s a left-wing middle class emerged that no longer voted Liberal.[citation needed] One effect of this was the success of a breakaway party, the Australian Democrats, founded in 1977 by former Liberal minister Don Chipp and members of minor liberal parties; other members of the left-leaning section of the middle-class became Labor supporters.[citation needed] On the other hand, the Liberals have done increasingly well in recent years among socially conservative working-class voters.[citation needed]However the Liberal Party's key support base remains the upper-middle classes; 16 of the 20 richest federal electorates are held by the Liberals, most of which are safe seats. In country areas they either compete with or have a truce with the Nationals, depending on various factors.

Question: In the 19th century, musical institutions emerged from the control of wealthy patrons, as composers and musicians could construct lives independent of the nobility. Increasing interest in music by the growing middle classes throughout western Europe spurred the creation of organizations for the teaching, performance, and preservation of music. The piano, which achieved its modern construction in this era (in part due to industrial advances in metallurgy) became widely popular with the middle class, whose demands for the instrument spurred a large number of piano builders. Many symphony orchestras date their founding to this era. Some musicians and composers were the stars of the day; some, like Franz Liszt and Niccolo Paganini, fulfilled both roles.
Try to answer this question if possible: Composers and musicians began to construct lives independent of what in the 19th century?
Answer: the nobility
Question: One of the most important events of the 19th century was the rise of Indian nationalism, leading Indians to seek first "self-rule" and later "complete independence". However, historians are divided over the causes of its rise. Probable reasons include a "clash of interests of the Indian people with British interests", "racial discriminations", "the revelation of India's past", "inter-linking of the new social groups in different regions", and Indians coming in close contact with "European education".
