The Analytical Engine incorporated an arithmetic logic unit, control flow in the form of conditional branching and loops, and integrated memory, making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete.

Two typical components of a CPU are the arithmetic logic unit ( ALU ), which performs arithmetic and logical operations, and the control unit ( CU ), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.

The control unit must communicate with both the arithmetic / logic unit and memory.

The fundamental components of a general-purpose computer are arithmetic logic unit | arithmetic and logic unit, control unit | control circuitry, storage space, and input / output devices.

" But if conspiracies exist, they rarely move history ; they make a difference at the margins from time to time, but with the unforeseen consequences of a logic outside the control of their authors: and this is what is wrong with ' conspiracy theory.

Hardwired control units are implemented through use of sequential logic units, featuring a finite number of gates that can generate specific results based on the instructions that were used to invoke those responses.

The hardwired approach has become less popular as computers have evolved as at one time, control units for CPUs were ad-hoc logic, and they were difficult to design.

Some computers were built using " writable microcode " — rather than storing the microcode in ROM or hard-wired logic, the microcode was stored in a RAM called a writable control store or WCS.

The compare and compute functions are completed within the controller which may be completed electronically through a Proportional Control, PI Controller, PID Controller, Bistable, Hysteretic control or Programmable logic controller.

* Use control logic implementation techniques ( logic synthesis using CAD tools ) to implement the other components-datapaths, register files, clocks

Computers, electronic clocks, and programmable logic controllers ( used to control industrial processes ) are constructed of digital circuits.

One of Icon's key concepts is that control structures are based on the " success " or " failure " of expressions, rather than on boolean logic, as in most other programming languages.

It meant that European ( and North American and Japanese ) capitalists were forced by the internal logic of their competitive system to seek abroad in less developed countries opportunities to control raw material, to find markets, and to find profitable fields of investment.

Microcode was originally developed as a simpler method of developing the control logic for a computer.

No known computer program can produce optimal logic, but even pretty good logic can vastly reduce the number of transistors from the number required for a ROM control store.

After it is assembled, the microprogram is then loaded to a control store to become part of the logic of a CPU's control unit.

The 6809's state machine and control logic, unlike many processors of the day, was mostly implemented using a large PLA and asynchronous random logic ( a trait of early designs and, partly, of RISC ) rather than microcoded.

The superior colliculus, which plays a major role in visual control of behavior in most vertebrates, shrinks to a small size in mammals, and many of its functions are taken over by visual areas of the cerebral cortex.

The BIOS provides a small library of basic input / output functions used to operate and control the peripherals ( such as the keyboard, text display functions and so forth ), and these software library functions are callable by external software.

* There is a basic form of modularity: files can be compiled separately and linked together, with control over which functions and data objects are visible to other files via and attributes.

Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions.

The gubernatorial and oblast-type Chekas retained in relationship to the transportation sections only control and investigative functions.

The primary functions of chromatin are: to package DNA into a smaller volume to fit in the cell, to strengthen the DNA to allow mitosis and meiosis and prevent DNA damage, and to control gene expression and DNA replication.

Some content-control software includes time control functions that empowers parents to set the amount of time that child may spend accessing the Internet or playing games or other computer activities.

Configuration APIs provide programmatic control of administrative functions of the call centre platform which are typically accessed by a human administrator through a Graphical User Interface ( GUI ).

He can also telepathically take away or control people's natural bodily functions and senses, such as sight, hearing, smell, taste, or even mutant powers.

Dedicated digital synthesizers frequently have the advantage of onboard accessibility, with switchable front panel controls to peruse their functions, whereas software synthesizers trump their dedicated counterparts with their additional functionality, against the handicap of a mouse-driven control system.

Ecosystems sustain life-supporting functions and produce natural capital through the regulation of continental climates, global biogeochemical cycles, water filtration, soils, food, fibres, medicines, erosion control, and many other natural features of scientific, historical, economic, or intrinsic value.

Common modifications include value changes in capacitors or resistors, adding true-bypass so that the effect's circuitry is no longer in the signal path, substituting higher-quality components, replacing the unit's original operational amplifiers ( op-amps ), or adding functions to the device such as allowing additional control of some factor or adding an additional output jack.

The ritual and religious treatment of meditation functions so that the individual learns to take the practice with seriousness ; learning to gradually control their degree of relaxation such that undesired and harmful schisms do not occur to the psyche.

Such higher order functions play a role analogous to built-in control structures such as loops in imperative languages.

This institution is charged with representing the Government of Spain on the island, and managing all the functions that are not under control of the Canarian Government.

The Airbus series of airliners used full-authority FBW controls beginning with their A320 series, see A320 flight control ( though some limited FBW functions existed on A310 ).

However, in the brain ( part of the central nervous system ), the " basal ganglia " is a group of nuclei interconnected with the cerebral cortex, thalamus and brainstem, associated with a variety of functions: motor control, cognition, emotions, and learning.

Now let us imagine a wing of B-52's, on alert near their `` positive control ( or fail-safe ) points '', the spots on the map, many miles from Soviet territory, beyond which they are forbidden to fly without specific orders to proceed to their targets.

So in these pages the term `` technology '' is used to include any and all means which could amplify, project, or augment man's control over himself and over other men.

and for this human beings must be firmly in control of the economics on which our society rests.

In secret he also acted as a member of the prisoners' Central Committee, which plotted sabotage, planned a few escapes, and maintained a hidden control over the wretched French slave-laborers.

William Wimsatt and Cleanth Brooks, it seems to me, have a penetrating insight into the way in which this control is effected: `` For if we say poetry is to talk of beauty and love ( and yet not aim at exciting erotic emotion or even an emotion of Platonic esteem ) and if it is to talk of anger and murder ( and yet not aim at arousing anger and indignation ) -- then it may be that the poetic way of dealing with these emotions will not be any kind of intensification, compounding, or magnification, or any direct assault upon the affections at all.

The novel, which is not merely dystopian but also brilliantly satiric, describes a future America where one-sixteenth of the population, the men who run advertising agencies and big corporations, control the rest of the people, the submerged fifteen-sixteenths who are the workers and consumers, with the government being no more than `` a clearing house for pressures ''.

The problem in the policy officer's mind thus begins to take shape as a galaxy of utterly complicated factors -- political, military, economic, financial, legal, legislative, procedural, administrative -- to be sorted out and handled within a political system which moves by consent in relation to an external environment which cannot be under control.
