In the years 1945, John Von Neumann defined the architecture of so-called stored-program computers. These computers are distinguished from their predecessors by the fact that they have a program composed of instructions which must be placed in a memory. Each instruction defines an action to be performed on data, for example an addition between two numbers. Previously, the first computers were not programmable. They were running only one program hardwired into the computer. Each run of a new program required rewiring the computer. ENIC  ( Electronic Numerical Integrator and Computer ), one of the first electronic computers completed in 1946, is the typical example of this type of machine. It occupied an area of ​​167 m 2 and consumed 150 kilowatts. On this machine, a multiplication was performed in 0.001 seconds; nowadays, such an operation takes 30 nanoseconds.

In order to gain a better understanding of this function and of the way in which the main components of the computer interact to execute a program, it is necessary to analyze in some detail the elements of the execution of a program. The simplest view is to view instruction processing as consisting of two steps. The processor (1) fetches the instructions from memory, one at a time, and (2) executes each instruction. The execution of a program consists of the repetition of this process of reading and executing the instruction. The execution of the instruction may involve several operations and depends on the nature of the instruction.

The architecture of stored-program computers includes the following elements:

  • A central unit responsible for executing the instructions of a program;
  • A central memory which contains the instructions of a program;
  • Input-output units supporting the exchange of information between the central processing unit-central memory pair and the exterior of the computer, via peripherals such as the keyboard, the mouse, the screen, etc.

The basic task that a computer performs is the execution of programs. The program to be executed consists of a set of instructions stored in memory. The processor carries out the work, executing the instructions specified in the program.

Where is a computer program stored?
The hard disk is one of the main components of a computer. Its role is to store computer data: it is therefore its memory. The hard disk contains the Windows system, your installed programs as well as your personal data.

What is a sequence of instructions in a program called?

A computer instruction is a step in a computer program. An instruction tells the computer the necessary action it must take before proceeding to the next instruction. A computer program is made up of a series of instructions.

Where are the instructions that make up the program being executed?
The Instruction Register (RI): this register contains the instruction being executed by the processor.

Where is the accumulator register located?
In computing, an accumulator is a special register, incorporated in some processor architectures, where the intermediate results of the ALU, or ALU in English (arithmetic logical unit), are poured

What is stored in RAM?
Computer memory, or random access memory, or RAM, is the short-term storage medium for your data. It stores the information your computer is using so it can be accessed quickly.

Where is the data stored?

The hard disk is one of the main components of a computer. Its role is to store computer data: it is therefore its memory.

What is in training?
Action to instruct someone, a group, to give them knowledge… instructions nf pl. Orders, explanations for the conduct of a business, a company.

What is the instruction?
The instruction is the stage of a criminal investigation which precedes the judgment and which is carried out by the examining magistrate. It is the action of a judge who gathers all the facts allowing to decide if it is necessary, according to the law, to prosecute people for an offense.

What are the different phases of an instruction?
reading instruction. decoding. operand search. execution. write result.

What do you call a sequence of instructions allowing you to obtain a result?

An algorithm is a sequence of detailed instructions which, if correctly executed, leads to a given result.

What is the role of cache memory? A Program Is A Sequence Of Instructions Stored In:
Cache memory temporarily stores information, data, and programs that are regularly used by your processor. When this data is required, the processor will automatically turn to cache memory in search of faster access to this data.

How are program instructions executed on a processor?
To execute the instruction, the processor looks for the input data (they may be in memory) it applies the operation. It then generates a result, which it stores, for example, in memory. It can also store it in special little slots in the processor called “registers”.

What is the role of the instruction register?
The instruction register (IR) contains the instruction being executed. This register is loaded at the start of the execution cycle by the instruction whose address is given by the program counter PC.

What is an instruction code?

1) What is an instruction code? An instruction is the basic operation that the processor can perform. Instructions are stored in main memory for processing by the processor.

What is the role of the ordinal counter?
In a processor, the ordinal counter or instruction pointer (in English: instruction pointer or program counter) is the register (often called PC) which contains the memory address of the instruction being executed or soon to be executed (it depends on the architecture).

Where is the ROM memory located?
Your desktop computer has a hard disk, which houses your operating system and all your data: software, files, photos, videos, etc. The ROM (Read-Only Memory ) is your computer’s hard drive.

What is local disk?
Your hard drive is listed in the “Computer” icon in Windows. The icon representing your main hard drive is labeled “C:” This is where Windows is installed. If your computer has a second hard drive, you will see a “Local Disk (D:)” icon.

What is the difference between ROM and RAM?

The Rom (Read Only Memory) stores data in a more or less large space; Ram (Random Access Memory) is a process that allows access to information. This is why the first is called read-only memory, and the second, living memory.

How is information stored in computers?
Existing storage hardware solutions Several data storage technologies exist: hard disks, optical disks, flash memory disks and the cloud. In current technologies, data is represented using binary code, i.e. only 0s and 1s. 09-Jun-2020

How is a file stored?
Data storage on traditional hard disk For the reading of these files, the writing or the modification of the bytes saved on a hard disk, reading heads shave the surface of the platters in order to transform the changes of polarity into interpretable data for your computer.

How is the data stored?
Finally, there is the simplest solution: storing your data in the cloud. There are a plethora of services, free in their version, paying in their advanced version (with larger storage capacities). The best known: Box, DropBox, OneDrive, Google Drive, iCloud, Oodrive.

What is the synonym of education?

  1. Action of instructing someone. Synonym: edification, education, teaching, fashioning, fashioning, training, lesson.
  2. How to open an instruction?
  3. A judicial investigation may be opened at the request of the prosecution or the victim. The examining magistrate can only inform by virtue of an indictment from the public prosecutor taken against a named or unnamed person (article 80 of the Code of Criminal Procedure).

In some cases, it is desirable to allow I/O exchanges to occur directly with memory. In such a case, the processor will give an I/O module authority to read or write memory, so that the I/O transfer occurs without hampering the processor. During the transfer, the I/O module issues read or write commands to memory, freeing the processor from responsibilities in the exchange. This operation is known as direct memory access (DMA ) .

As we have seen, the central processing unit and the central memory are the two components that have a fundamental role in the process of running programs. The central memory contains the instructions and data of the programs in the addressable words which compose it. The central unit or processor executes these instructions one after the other, like an automaton which sequences the steps of FETCH, search for operands and execution of the operation.

In 50 years, the power of processors and its ability to execute ever more instructions in a reduced time has continued to increase and continues to constitute an important issue given the ever greater volumes of data to be processed and the the expansion of automated processing. Cache memory, pipeline, increase in processor frequency, multi-core architecture contribute to fulfilling this objective by acting according to three principles:
