Are rock songs and discos the same?

Disco is short for discotheque, which originally meant record dance, and began as a reference to the music of black people dancing to recordings in nightclubs, becoming a catch-all term for virtually any current dance music in the 1970s. Compared to rock, it is characterized by a strong, non-discriminatory, metronome-like 4/4 beat and simple lyrics and tunes, and was first introduced in the United States in 1977 with the film recording Weekend Fever by the Australian pop group the Bee Gees. Disco was often synthesized and recorded in studios, but was gradually replaced in the early 1980s by other, less rhythmic, slower popular dance music due to its monotonous tempo and similarity in style

Rock and roll is a style of popular music that originated in the United States in the 1940s and 1950s. Originally, rock and roll was a combination of black blues, gospel music, jazz and country. Elements of rock 'n' roll can be traced back to the blues of the 1920s and the country of the 1930s, but it was only in the 1950s that it began to gain popularity as a separate style of music. "Rock and roll is a broader concept that encompasses the range of ideas and cultural movements that accompanied the birth of rock and roll, and is rooted in rock and roll, but is not limited to rock and roll as a musical style. For example, the hippies of the 60s and 70s (love and peace, one of the most influential social movements in rock music), punk and No-Wave in the late 70s, New Wave after punk (which also appeared in other arts such as literature), and the UK's Sharp Dance Culture in the early 90s (a youth movement that used electro music as a major vehicle for its political involvement, which is also considered a branch of rock culture). (also seen as a branch of rock culture).
