基本参数:DSQC639 3HACO25097-001/13 ABB  核算机操控机组模块

核算机体系由**“硬件”和“软件”两部分组成**。

硬件是指看得见摸得着的各种电子元器件。如主机、键盘、鼠标等。

软件毛不见摸不着，但在逻辑上，咱们确实可以感和到它的存在，它由人们事前编制的具有某种功用的程序组成。比方操作体系、编程言语等。核算机的软件一般又分为:体系软件和运用软件。

体系软件:又称为体系程序，首要用来处理整个核算机体系，监督服务，使体系资源得到合理调度。它包括:操作体系、言语处理程序、数据库处理体系、网络软件、服务程序等。

运用软件:又称为运用程序，它是用户根据需要事前编制的程序。比方QQ、微信等。1.2核算机的分类

核算机的品种许多，从不同的角度看，有不同的分类。

1.按照核算机的处理信息的方式，可以分为数字核算机和模仿核算机。

数字核算机:经过信号的两种不同状态(1和0)来标明信息，可以方便地对数字信号进行算术和逻辑运算，具有速度快、精度高、便于存储等优点。一般讲的核算机一般是指数字核算机。

模仿核算机:一般只能处理模仿信号，如接连改动地电压、电流和温度等。这类核算机运用邻域有限，通用性不强。1.按照核算机通用性地差异，核算机可以分为专用核算机和通用核算机。

专用核算机:专门为某一问题而规划的核算机。功翰比较单一，对运用环境坨适应性很差。例做核算导郸单道的专用核算机。

通用核算机:各行业和各种环境都能徳用的核算机，一般具有较高的运算速度、较大的内存容量。咱们平常运用的个人台式核算机都属于通用核算机。

1.按照核算机体系的规划和处理才能，通用核算机可以分为以下几类:微型机

核算机的诞生与展开2.1冯·诺依曼体系

19454年，被称为“核算机之父”的美籍匈牙利科学家冯·诺依曼在研讨EDVAC时提出了“存储程序”的概念。以此概念为基础的各类核算机称为冯·诺依曼机。它的特色可以归驶口下:

核算机的结构应由五大部分组成:运算器、操控器、存储器、输入设备、输出设备。指令和数据以平等位置寄存在存储器内，并可按地址寻访。

指令和数据均用二进制数标明。

指令由操作码和地址码组成，操作码用来标明操作码的性质，地址码用来标明操作数在存储器中的方位。指令在存储器内按顺京寄存

Product introduction

Basic parameters :DSQC639 3HACO25097-001/13 ABB computer control unit module

A computer system consists of two parts: hardware and software.

Hardware refers to the various electronic components that can be seen and touched. Such as host, keyboard, mouse, etc.

Software is invisible, but logically we can feel its existence, it is composed of people in advance to have a certain function of the program. Such as operating systems, programming languages, etc. Computer software is usually divided into system software and application software.

System software: also known as system program, mainly used to manage the entire computer system, monitor services, so that system resources are reasonably scheduled. It includes: operating system, language processing program, database management system, network software, service program, etc.

Application software: also known as application program, it is the user according to the needs of the program prepared in advance. Such as QQ, wechat and so on. 1.2 Classification of computers

There are many kinds of computers, and from different perspectives, there are different classifications.

1. According to the way computers process information, they can be divided into digital computers and analog computers.

Digital computer: through two different states of the signal (1 and 0) to represent the information, you can easily perform arithmetic and logic operations on the digital signal, with the advantages of fast speed, high precision, easy storage and so on. Generally speaking, the computer is generally an exponential computer.

Analog computer: Generally can only process analog signals, such as continuously changing voltage, current and temperature. The application area of this kind of computer is limited, and the universality is not strong. 1. According to the differences in the universality of computers, computers can be divided into special computers and general computers.

Dedicated computer: A computer designed specifically for a particular problem. Gong Han is relatively simple, and the adaptability to the application environment is very poor. An example of a calculation guide to a single special computer.

General-purpose computer: a computer that can be used in various industries and environments, generally having high computing speed and large memory capacity. The personal desktop computers we use are all general-purpose computers.

1. According to the scale and processing power of the computer system, general-purpose computers can be divided into the following categories: microcomputers

Minicomputer mainframe supercomputer

The birth and development of computers 2.1 Von Neumann System

In 19454, the Hungarian-American scientist von Neumann, known as the "father of the computer", proposed the concept of "stored program" while studying the EDVAC. The various types of computers based on this concept are called von Neumann machines. Its characteristics can be returned to the port under:

The structure of the computer should be composed of five parts: arithmetic, controller, memory, input device, output device. Instructions and data are stored in memory on an equal footing and can be accessed by address.

Instructions and data are represented in binary numbers.

The instruction is composed of an opcode and an address code, the opcode is used to represent the properties of the opcode, and the address code is used to represent the location of the operand in the memory. Instructions are stored in the memory as sequential
