Italy (ⁱ/ˈɪtəli/; Italian: Italia [iˈtaːlja]), officially the Italian Republic (Italian: Repubblica Italiana), is a unitary parliamentary republic in Europe. Italy covers an area of 301,338 km² (116,347 sq mi) and has a largely Mediterranean and temperate climate; due to its shape, it is often referred to in Italy as lo Stivale (the Boot). With 61 million inhabitants, it is the 4th most populous EU member state. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino and Vatican City.

Since ancient times, Greeks, Etruscans and Celts have inhabited the south, centre and north of the Italian Peninsula respectively. Rome ultimately emerged as the dominant power, conquering much of the ancient world and becoming the leading cultural, political, and religious centre of Western civilisation. The legacy of the Roman Empire is widespread and can be observed in the global distribution of civilian law, Republican governments, Christianity and the latin script.

Roman Italy

Roman Italy was created officially by the Roman Emperor Augustus with the Latin name Italia. It was the first time in history that the Italian peninsula (from the Alps to the Ionian Sea) was united under the same name. In the year 292, the three islands of Corsica, Sardinia and Sicily were added to Roman Italy by Emperor Diocletianus.

Characteristics

Italy (Italia in Latin and Italian) was the name of the administrative division of the Italian peninsula during the Roman era. It was not a province, but became the territory of the city of Rome, thus having a special status. Following the end of the Social War (91–88 BC), Rome had allowed its Italian allies (socii) full rights in Roman society and granted the Roman citizenship to all the Italic peoples.

After having been for centuries the heart of the Empire, from the 3rd century the government and the cultural center began to move eastward: first the Edict of Caracalla in 212 AD extended Roman citizenship to all free men within the imperial boundaries, then during Constantine's reign (306–337) the seat of the Empire was moved to Constantinople in 330 AD.

Driver circuit

In electronics, a driver is an electrical circuit or other electronic component used to control another circuit or component, such as a high-power transistor, liquid crystal display (LCD), and numerous others.

They are usually used to regulate current flowing through a circuit or is used to control the other factors such as other components, some devices in the circuit. The term is often used, for example, for a specialized integrated circuit that controls high-power switches in switched-mode power converters. An amplifier can also be considered a driver for loudspeakers, or a constant voltage circuit that keeps an attached component operating within a broad range of input voltages.

Typically the driver stage(s) of a circuit requires different characteristics to other circuit stages. For example in a transistor power amplifier, typically the driver circuit requires current gain, often the ability to discharge the following transistor bases rapidly, and low output impedance to avoid or minimize distortion.

Device driver

In computing, a device driver (commonly referred to as a driver) is a computer program that operates or controls a particular type of device that is attached to a computer. A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details of the hardware being used.

A driver communicates with the device through the computer bus or communications subsystem to which the hardware connects. When a calling program invokes a routine in the driver, the driver issues commands to the device. Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface.

Purpose

Device drivers simplify programming by acting as translator between a hardware device and the applications or operating systems that use it. Programmers can write the higher-level application code independently of whatever specific hardware the end-user is using.

Driving

Driving most often refers to the controlled operation and movement of a motorized vehicle, such as a car, truck, or bus.

Etymology

The origin of the term driver, as recorded from the 15th century, refers to the occupation of driving working animals, especially pack horses or draft horses. The verb ' to drive ' in origin means "to force to move, to impel by physical force". It is first recorded of electric railway drivers in 1889 and of a motor-car driver in 1896. Early alternatives were motorneer,motor-man, motor-driver or motorist. French favors "conducteur" (the English equivalent, "conductor", being used —from the 1830s— not of the driver but of the person in charge of passengers and collecting fares), while German influenced areas adopted Fahrer (used of coach-drivers in the 18th century, but shortened about 1900 from the compound Kraftwagenfahrer), and the verbs führen, lenken, steuern —all with a meaning "steer, guide, navigate"— translating to conduire.
