Alienware assembles desktops, notebooks, workstations, and PC gaming consoles. Unix operating systems are widely used in modern servers, workstations, and mobile devices. GPUs are used in embedded systems, mobile phones, personal computers, workstations, and game consoles. SCSI is popular on high-performance workstations, servers, and storage appliances. Tools typically used are keyboards, drum machines, softsynths and digital audio workstations. It is intended for use in supercomputers, servers, and high-end workstations. They are usually integrated using hardware (samplers) or software such as digital audio workstations. SMFs are created as an export format of software sequencers or hardware workstations. RS/6000 was originally a line of workstations and servers. They were used in high-end workstations and servers by SGI, among others. Intel's first Itanium workstations and servers, released in 2000, implemented EFI 1.02. These include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. Sequencers used for audio recording are called digital audio workstations (or DAWs). It permits users to share SECRET REL information from their national C2 system workstations. The later IRIS 2000 and 3000 models developed into full UNIX workstations.
