The ABC pioneered important elements of modern computing, including binary arithmetic and electronic switching elements, [5] but its special-purpose nature and lack of a changeable, stored program distinguish it from modern computers. The computer was designated an IEEE Milestone in 1990. [6]

The Blue Gene/P supercomputer "Intrepid" at Argonne National Laboratory (pictured 2007) runs 164,000 processor cores using normal data center air conditioning, grouped in 40 racks/cabinets connected ...
Special-purpose computer languages have always existed in the computer age, but the term "domain-specific language" has become more popular due to the rise of domain-specific modeling. Simpler DSLs, particularly ones used by a single application, are sometimes informally called mini-languages.
An embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. [1] [2] It is embedded as part of a complete device often including electrical or electronic hardware and mechanical parts.
The U.S. military's SAGE system was the first large-scale example of such a system, which led to a number of special-purpose commercial systems such as Sabre. [140] In the 1970s, computer engineers at research institutions throughout the United States began to link their computers together using telecommunications technology.
It meets most definitions of "mini" in terms of power and size, but was designed and built to be used as an instrumentation system in labs, not as a general-purpose computer. [11] Many similar examples of small special-purpose machines exist from the early 1960s, including the UK Ferranti Argus and Soviet UM-1NKh.
A workstation is a special computer designed for technical or scientific applications. [2] Intended primarily to be used by a single user, [2] they are commonly connected to a local area network and run multi-user operating systems.
A bastion host is a special-purpose computer on a network specifically designed and configured to withstand attacks, so named by analogy to the bastion, a military fortification. The computer generally hosts a single application or process, for example, a proxy server or load balancer , and all other services are removed or limited to reduce ...
