基本參數(shù):DSQC639 3HACO25097-001/13 ABB 計(jì)算機(jī)控制機(jī)組模塊
計(jì)算機(jī)系統(tǒng)由**“硬件”和“軟件”兩部分組成**。
硬件是指看得見(jiàn)摸得著的各種電子元器件。如主機(jī)、鍵盤、鼠標(biāo)等。
軟件毛不見(jiàn)摸不著，但在邏輯上，我們確實(shí)可以感和到它的存在，它由人們事先編制的具有某種功能的程序組成。比如操作系統(tǒng)、編程語(yǔ)言等。計(jì)算機(jī)的軟件通常又分為:系統(tǒng)軟件和應(yīng)用軟件。
系統(tǒng)軟件:又稱為系統(tǒng)程序，主要用來(lái)管理整個(gè)計(jì)算機(jī)系統(tǒng)，監(jiān)視服務(wù)，使系統(tǒng)資源得到合理調(diào)度。它包括:操作系統(tǒng)、語(yǔ)言處理程序、數(shù)據(jù)庫(kù)管理系統(tǒng)、網(wǎng)絡(luò)軟件、服務(wù)程序等。
應(yīng)用軟件:又稱為應(yīng)用程序，它是用戶根據(jù)需要事先編制的程序。比如QQ、微信等。1.2計(jì)算機(jī)的分類
計(jì)算機(jī)的種類很多，從不同的角度看，有不同的分類。
1.按照計(jì)算機(jī)的處理信息的方式，可以分為數(shù)字計(jì)算機(jī)和模擬計(jì)算機(jī)。
數(shù)字計(jì)算機(jī):通過(guò)信號(hào)的兩種不同狀態(tài)(1和0)來(lái)表示信息，可以方便地對(duì)數(shù)字信號(hào)進(jìn)行算術(shù)和邏輯運(yùn)算，具有速度快、精度高、便于存儲(chǔ)等優(yōu)點(diǎn)。通常講的計(jì)算機(jī)一般是指數(shù)字計(jì)算機(jī)。
模擬計(jì)算機(jī):一般只能處理模擬信號(hào)，如連續(xù)變化地電壓、電流和溫度等。這類計(jì)算機(jī)應(yīng)用鄰域有限，通用性不強(qiáng)。1.按照計(jì)算機(jī)通用性地差異，計(jì)算機(jī)可以分為專用計(jì)算機(jī)和通用計(jì)算機(jī)。
專用計(jì)算機(jī):專門為某一問(wèn)題而設(shè)計(jì)的計(jì)算機(jī)。功翰比較單一，對(duì)應(yīng)用環(huán)境坨適應(yīng)性很差。例做計(jì)算導(dǎo)鄲單道的專用計(jì)算機(jī)。
通用計(jì)算機(jī):各行業(yè)和各種環(huán)境都能徳用的計(jì)算機(jī)，一般具有較高的運(yùn)算速度、較大的內(nèi)存容量。我們平常使用的個(gè)人臺(tái)式計(jì)算機(jī)都屬于通用計(jì)算機(jī)。
1.按照計(jì)算機(jī)系統(tǒng)的規(guī)模和處理能力，通用計(jì)算機(jī)可以分為以下幾類:微型機(jī)
小型機(jī)大型機(jī)超級(jí)計(jì)算機(jī)
計(jì)算機(jī)的誕生與發(fā)展2.1馮·諾依曼體系
19454年，被稱為“計(jì)算機(jī)之父”的美籍匈牙利科學(xué)家馮·諾依曼在研究EDVAC時(shí)提出了“存儲(chǔ)程序”的概念。以此概念為基礎(chǔ)的各類計(jì)算機(jī)稱為馮·諾依曼機(jī)。它的特點(diǎn)可以歸駛口下:
計(jì)算機(jī)的結(jié)構(gòu)應(yīng)由五大部分組成:運(yùn)算器、控制器、存儲(chǔ)器、輸入設(shè)備、輸出設(shè)備。指令和數(shù)據(jù)以同等地位存放在存儲(chǔ)器內(nèi)，并可按地址尋訪。
指令和數(shù)據(jù)均用二進(jìn)制數(shù)表示。
指令由操作碼和地址碼組成，操作碼用來(lái)表示操作碼的性質(zhì)，地址碼用來(lái)表示操作數(shù)在存儲(chǔ)器中的位置。指令在存儲(chǔ)器內(nèi)按順京存放
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
