Manual pages sections

Almost all UNIX operating systems have voluminous documentation known as manual pages. Every page is a document. If one wants to read a page then the command man at a shell prompt will show the manual, for example, "man ftp". Pages are referred by using the notation "name(manual-section)", for example time(1).
