Abstract

A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations automatically. Modern computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a "complete" computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for "full" operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, which links hundreds of millions of other computers and users. Early computers were meant to be used only for calculations. Simple manual instruments like the abacus have aided people in doing calculations since ancient times. Early in the Industrial Revolution, some mechanical devices were built to automate long tedious tasks, such as guiding patterns for looms. More sophisticated electrical machines did specialized analog calculations in the early 20th century. The first digital electronic calculating machines were developed during World War II. The first semiconductor transistors in the late 1940s were followed by the silicon-based MOSFET (MOS transistor) and monolithic integrated circuit (IC) chip technologies in the late 1950s, leading to the microprocessor and the microcomputer revolution in the 1970s. The speed, power and versatility of computers have been increasing dramatically ever since then, with transistor counts increasing at a rapid pace (as predicted by Moore's law), leading to the Digital Revolution during the late 20th to early 21st centuries. Conventionally, a modern computer consists of at least one processing element, typically a central processing unit (CPU) in the form of a microprocessor, along with some type of computer memory, typically semiconductor memory chips. The processing element carries out arithmetic and logical operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices include input devices (keyboards, mice, joystick, etc.), output devices (monitor screens, printers, etc.), and input/output devices that perform both functions (e.g., the 2000s-era touchscreen). Peripheral devices allow information to be retrieved from an external source and they enable the result of operations to be saved and retrieved.Piracy is an act of robbery or criminal violence by ship or boat-borne attackers upon another ship or a coastal area, typically with the goal of stealing cargo and other valuable goods. Those who conduct acts of piracy are called pirates, while the dedicated ships that pirates use are called pirate ships. The earliest documented instances of piracy were in the 14th century BC, when the Sea Peoples, a group of ocean raiders, attacked the ships of the Aegean and Mediterranean civilizations. Narrow channels which funnel shipping into predictable routes have long created opportunities for piracy, as well as for privateering and commerce raiding. Historic examples include the waters of Gibraltar, the Strait of Malacca, Madagascar, the Gulf of Aden, and the English Channel, whose geographic structures facilitated pirate attacks. A land-based parallel is the ambushing of travelers by bandits and brigands in highways and mountain passes. Privateering uses similar methods to piracy, but the captain acts under orders of the state authorizing the capture of merchant ships belonging to an enemy nation, making it a legitimate form of war-like activity by non-state actors.While the term can include acts committed in the air, on land (especially across national borders or in connection with taking over and robbing a car or train), or in other major bodies of water or on a shore, in cyberspace, as well as the fictional possibility of space piracy, it generally refers to maritime piracy. It does not normally include crimes committed against people traveling on the same vessel as the perpetrator (e.g. one passenger stealing from others on the same vessel). Piracy or pirating is the name of a specific crime under customary international law and also the name of a number of crimes under the municipal law of a number of states. In the early 21st century, seaborne piracy against transport vessels remains a significant issue (with estimated worldwide losses of US$16 billion per year in 2004), particularly in the waters between the Red Sea and Indian Ocean, off the Somali coast, and also in the Strait of Malacca and Singapore. Today, pirates armed with automatic weapons, such as assault rifles, and machine guns, grenades and rocket propelled grenades use small motorboats to attack and board ships, a tactic that takes advantage of the small number of crew members on modern cargo vessels and transport ships. They also use larger vessels, known as "mother ships", to supply the smaller motorboats. The international community is facing many challenges in bringing modern pirates to justice, as these attacks often occur in international waters. Some nations have used their naval forces to protect private ships from pirate attacks and to pursue pirates, and some private vessels use armed security guards, high-pressure water cannons, or sound cannons to repel boarders, and use radar to avoid potential threats.Copy may refer to: Copying or the product of copying (including the plural "copies"); the duplication of information or an artifact Cut, copy and paste, a method of reproducing text or other data in computing File copying Photocopying, a process which makes paper copies of documents and other visual images Fax, a telecommunications technology used to transfer copies of documents, especially over the telephone network Facsimile, a copy or reproduction that is as true to the original source as possible Replica, a copy closely resembling the original concerning its shape and appearance Term of art in U.S. copyright law meaning a material object in which a work of authorship has been embodied, such as a book Copy (command), a shell command on DOS and Windows systems Copy (written), written content in publications, in contrast to photographs or other elements of layout Copy (album), the debut album of the electronica artist Mitsuki Aira Copy (musician), the Portland-based electronic music artist "Copy", a procedure word or response indicating a satisfactory receipt of the last radio transmission COPY, a COBOL keyword
