Question: Information: - Instrumental rock is rock music that emphasizes musical instruments and features very little or no singing. Examples of instrumental rock can be found in practically every subgenre of rock, often from musicians who specialize in the style. Instrumental rock was most popular from the mid-1950s to mid-1960s, with artists such as Bill Doggett Combo, Jimmy Reed, Earl Bostic, The Fireballs, The Shadows, and The Ventures. Surf music had many instrumental songs. Many instrumental hits came from the R&B world. Funk and disco produced several instrumental hit singles during the 1970s. The Allman Brothers Band have many instrumentals. Jeff Beck also recorded two instrumental albums in the 1970s. Progressive rock and art rock performers of the 1960s and 1970s did many virtuosic instrumental performances. - Jazz is a music genre that originated amongst African Americans in New Orleans, United States, in the late 19th and early 20th centuries. Since the 1920s jazz age, jazz has become recognized as a major form of musical expression. It emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African American and European American musical parentage with a performance orientation. Jazz is characterized by swing and blue notes, call and response vocals, polyrhythms and improvisation. Jazz has roots in West African cultural and musical expression, and in African-American music traditions including blues and ragtime, as well as European military band music. Although the foundation of jazz is deeply rooted within the Black experience of the United States, different cultures have contributed their own experience and styles to the art form as well. Intellectuals around the world have hailed jazz as "one of America's original art forms". - Out of the Shadows is a 1962 rock album by British group The Shadows . It was their second album . - A ballad is a form of verse, often a narrative set to music. Ballads derive from the medieval French "chanson balladee" or "ballade", which were originally "danced songs". Ballads were particularly characteristic of the popular poetry and song of the British Isles from the later medieval period until the 19th century. They were widely used across Europe, and later in the Americas, Australia and North Africa. Ballads are 13 lines with an ABABBCBC form, consisting of couplets (two lines) of rhymed verse, each of 14 syllables. - The Shadows are a British instrumental rock group, and Cliff Richard's backing band, with 69 UK chart singles from the 1950s to the 2000s, 35 credited to the Shadows and 34 to Cliff Richard and the Shadows. The group, who were in the forefront of the UK beat-group boom, were the first backing band to emerge as stars. As pioneers of the four-member instrumental format, the band consisted of lead guitar, rhythm guitar, bass guitar and drums. Their range covers pop, rock, surf rock and ballads with a jazz influence. - Sir Cliff Richard (born Harry Rodger Webb, 14 October 1940) is a British pop singer, musician, performer, actor and philanthropist.

Question: Information: - 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 typically 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 . - A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. The ability of computers to follow a sequence of operations, called a "program", make computers very flexible and useful. Such computers are used as control systems for a very wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones. The Internet is run on computers and it connects millions of other computers. - An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. All computer programs, excluding firmware, require an operating system to function. - A computer program is a collection of instructions that performs a specific task when executed by a computer. A computer requires programs to function, and typically executes the program's instructions in a central processing unit. - A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. The computer industry has used the term "central processing unit" at least since the early 1960s. Traditionally, the term "CPU" refers to a processor, more specifically to its processing unit and control unit (CU), distinguishing these core elements of a computer from external components such as main memory and I/O circuitry.
