U.S. computer to the computer classification of materials in general using two classification criteria: According to the main circuit to points, the computer is divided into the first generation of vacuum tube computers, computers and other second-generation transistors ... ... this is actually the history of development of mainframe; by hardware sub-divided into supercomputer, mainframe, mid-sized machine, minicomputer, microcomputer, etc., this classification method is also old too old, because some of the performance of the server than in the past but also strong mainframe. In view of this, the above classifications and unreasonable, in the network is becoming increasingly popular today. We should re-examine the computer's classification criteria.
Reclassified according to age
1. Reclassified according to age
Reclassified according to age, you can put the computer is divided into:
(1) mainframe stage, the 20th century, 40-50 years, are the first generation of vacuum tube computers. Experienced a tube digital computer, transistor digital computers, integrated circuits, digital computers and large-scale integrated circuits the development process of digital computers, computer technology has gradually matured. ;
(2) Small Computer stages 60-70 during the 20th century, are of large host the first "narrow" and to meet the small and medium-sized units of information processing requirements, lower cost, the price may be accepted;
(3) micro-computer stage, the 20th century, 70-80 years, are of large mainframe second "narrow" and the United States in 1976 Apple was established in 1977 launched a AppleII on computer, great success. 1981 IBM launched IBM-PC, since then it has undergone a number of generations of evolution, the occupation of the personal computer market, making personal computers has been a great deal of popularity;
(4) client / server phase, the C / S stage. With the 1964 IBM and American Airlines established the first global on-line booking system, put the United States at the time of booking more than 2000 terminals using telephone lines to connect together, marking the computer into the client / server stage model is still widely used. In client / server network, servers are the core of the network, and client networks are the basis for the client to rely on the server to obtain the required network resources, while the server for the client must provide network resources. C / S structure are able to give full play to the advantages of client PC's processing capability, a lot of work on the client and then submitted to deal with servers, greatly reduces the pressure on server;
(5) Internet stage, also known as the Internet, Internet, Internet stage. That is, the Internet WAN, LAN and stand-alone communication protocol in accordance with certain of the international computer network. Internet began in 1969, are in the ARPA (the U.S. Department of Defense Research Projects Agency) under an agreement to develop the southwestern United States universities (UCLA (University of California, Los Angeles Campus), StanfordResearchInstitute (Stanford University Research Institute), UCSB ( University of California) and UniversityofUtah (University of Utah)) of the four major computer linking. Since then experienced a text to picture, and now voice, video and other stage, the bandwidth getting faster and faster growing function. The characteristics of the Internet are: global, mass sex, anonymous sex, interactive sex, growth, and flat, and real-time, multimedia, and addiction, sexual hubbub. The significance of the Internet should not be underestimated. It is a human into a solid step in the global village;
(6) Cloud Computing era, from 2008, Cloud Computing (Cloud Computing) concept of progressive pop up, it is becoming a popular and mass (Popular) terms. Cloud computing as "a revolutionary computing model", as it allows super-computing power via the Internet free flow became possible. Enterprises and individual users no longer need to purchase expensive hardware investment costs, is only required to purchase the lease through the Internet computing power, users only the functionality necessary for themselves to pay, while the elimination of traditional software in the hardware, software, the cost of professional skills. Cloud computing allows users from the technical and deployment on the complexity of the applications received. Cloud computing encompasses the development, architecture, load balancing and business models and so on, are the software industry in the future model. It is based on Web services to Internet-centric.
2. Why must it be so classified
According to this classification, you can more fully reflect the rapid development of information technology, not just the first generation of mainframe development stage. In fact, from the first generation of mainframe use of ultra-large-scale integrated circuits to the present, all the computers are used in almost all the ultra-large-scale integrated circuits. This classification, there was no requirement at all stages of the specific start time, because their development is not simply Tandem relationship, but parallel development. That is to say, which is not in the specific point in time, all the mainframe into a minicomputer, and Minicomputer also did not completely replace the mainframe, they are co-exist. But one thing must be noted, mainframe, mini-computers and high-grade micro-computer in the server field of the main job (the following should be mentioned).
Reclassified according to the hardware
In addition, there are the people classified by the size of the hardware, put the computer into a giant computer, large computers, medium-sized computers, mini computers, micro-computers. Some sounds reasonable, but this classification is defined in 1989, after 20 years of development, this classification clearly has become obsolete, because the majority of the 80's server has been eliminated, and now some of the server than then the function of large-scale computer still strong, but much smaller. Therefore, it is by someone the computer hardware to re-classification, divided into: servers, workstations, desktops, notebook computers, handheld devices five categories.
(1) server: server, called the English Server, refers specifically to certain high-performance computers, through the network, external provision of services. Compared to ordinary computer, the stability, security, performance, etc. are more demanding, so in the CPU, chipset, memory, disk systems, networks and general computer hardware is different. Servers are network nodes, storage, 80 percent deal with network data,Information, in the network play a decisive role. They are for the client computer provides a variety of services, high-performance computers, mainly reflected in its high-performance high-speed computing power, a long period of reliable operation, a strong external data handling capacity and so on. Server components and general computer similar, but also have the processor, hard disk, memory, system bus, but because it is a specific web application specifically designed, so server and PC in the treatment capacity, stability, reliability, security , scalability, manageability and so very different;
(2) workstations: workstations English called Workstation, is a personal computer and distributed network computing as the foundation, mainly for professional applications, with powerful data computing and graphics, image processing capabilities, to meet the engineering design, animation production, scientific research, software development, financial management, information services, simulation and other specialized areas of design and development of high-performance computers. It belongs to a high-end computer, the general has a larger screen display and large-capacity memory and hard drive, also has a strong information processing capabilities and high-performance graphics, image processing functions and networking functions;
(3) desktop: desktop, called the English Desktop, also known as desktop machines, for the now very popular micro-computer, the majority of people at home and companies are used in desktop machines. The performance desktop laptop relatively strong;
(4) Laptop: Laptop English called Notebook Computer (referred to as NB) or Laptop, also known as hand-held computer or laptop (Hong Kong and Taiwan are known as notebook computer), is a small, portable personal computers, typically 1-3 kilograms of weight. It is similar to desktop architecture, but with better portability: including liquid crystal displays, which the smaller, lighter weight. Laptop except the keyboard, it also provided touchpad (TouchPad), or touch points (Pointing Stick), to provide a better positioning and input capabilities. Laptop can be broadly divided into 4 categories: business type, fashion-based, multimedia applications, special purpose. Business-based laptop in general can be summed up as mobile and strong, long battery life, many commercial software; fashion-type appearance of the main fashion for women; multimedia application-oriented laptop has a stronger graphics, image processing and multimedia capabilities, in particular are playing capability, for the enjoyment of products. Moreover, many multimedia laptop has a relatively strong independent graphics and sound card (both support high-definition), and has a larger screen; special purpose laptop are serving professionals in the heat, cold, low pressure, war harsh environment such as the use of models, some of the more bulky, such as pre-Olympic Games in the "base camp of Mount Qomolangma ASUS IT Service Area" Asus laptop used;
(5) handheld devices: handheld device, called the English Handheld, type more, such as PDA, SmartPhone, Smart mobile phone, 3G mobile phone, Netbook, EeePC, etc., which is characterized by small size. As the 3G era, handheld devices will be given a greater development, and its function will become increasingly strong.
Change the truth are the same, with the changing times, some really need to abandon the concept, and some re-definition of the standard required. Today, we come to re-examine the classification of computer standards, will help us better understand the computer and the use of computers.

With the computer to redefine the classification standards
computers, the second generation of computers tube etc... this transistor computer is the development history of the mainframe, According to the hardware, divided into giant computer mainframe, medium, machine, etc, this year, minicomputers classification method and old old, because some server performance than mainframes. In view of the above, the classification method is reasonable, in the Internet is becoming more and more popular today. We should rethink the classification standard of computer.
According to the classification 1. According to the classification According to the classification, the computer can be divided into: (1) mainframes stage, the 20th century 40-50, is the first generation of computer. Tube, The digital computer, tube through digital computer and integrated circuit transistor digital computer and large scale integrated circuit of digital computer development course, computer technology gradually mature. , (2) small computer stage, 20 centuries 60-70, is to mainframes first "shrink", and can satisfy the small and medium-sized enterprises and institutions information processing requirements, low cost, the price can be accepted, (3) microcomputer stage, 20th century 70-80s, is on the second mainframes "narrow" in 1976, America, 1977 founded apple computer, AppleII released great success. IBM launched in 1981, PC IBM - has undergone several generations of evolution, occupied the PC market, make the personal computer greatly. (4) to the client/server stages, namely, C/S. In 1964, with IBM and American airlines established the first global online booking system, the United States was more than 2000 book with the terminal line connected to the computer, marks into the client/server stage, this model is still in use. In the client/server network, server is the core, and client network is based on network, server to the client and server's network resources for clients, providing a network of resources to. C/S structure is that can give full play to the client, many PC handling ability in the client can be processed to submit to the server, significantly reducing the pressure of servers, (5), also known as the Internet stage, the Internet, the Internet network stage. The Internet is single LAN and wan, according to certain communication protocols of international computer network. In 1969, the Internet started in ARPA (the U.S. defense department of research program) under the agreement will of the southwestern United States university (UCLA (university of California, Los Angeles, Stan StanfordResearchInstitute (Stanford university and research institute), UCSB (university of California university of Utah UniversityofUtah) and (4) the main computer. After the text to pictures and experience to voice and video stage, bandwidth and faster, function stronger. The Internet is characterized global, mass, anonymity, interactivity, growth and flat, real-time, multimedia, addiction, noise. The significance of the Internet should not be underestimated. It is the global solid step towards human, (6) Cloud calculative era, from 2008, Computing clouds Cloud (Computing), it gradually Popular concept is to become a Popular and popularization of Popular (). Cloud calculative is regarded as a "revolutionary calculation model", because it makes the supercomputing power through the Internet freely. Enterprise and individual users need to purchase cost into expensive hardware, need only through the Internet to purchase, lease calculation for the needs of the user only pay, and eliminate function of traditional software in hardware, software, and professional skills. Cloud calculative let users from technology and deployment of complexity and application. Cloud calculative include development, structure, load balancing and commercial mode, the future is software pattern. It is based on Web services to the Internet for the center. 2 why it should be classified According to this, can reflect the information technology development by leaps and bounds, and is not only the first generation of mainframes stage of development. In fact, from the generation mainframes using large scale integrated circuit began to now, all the computer USES is almost every large scale integrated circuit. This classification, and not at all stages of the specific chronologically, because of their development is not simply a series of parallel development relationship, but. Namely, not in time, all of which has become the mainframe, minicomputers and marketing without completely replace the mainframe, they are. But must pay attention, mainframes, small computer and high-grade microcomputer mainly work in the server (below to mention).
According to the hardware In addition, there is a man of hardware, the size of the computer, the computer into giant mainframe computers, medium-sized computers, small computer, microcomputer. Sounds reasonable, but this classification is defined in 1989, after 20 years of development, the classification method has become obsolete, because apparently 1980s server most were out, but now some server than large computer functions to be stronger, but much less. Therefore, some now will the computer hardware, according to classified into: server, workstations, desktop and notebook computers, handheld devices five categories. Server: (1) the Server, called Server shows some English, computer, through the network performance, providing services. Compared with ordinary computers, stability, security, performance requirements, etc in higher CPU, memory and disk chipsets, network system, hardware and ordinary computers vary. Server nodes on the network, storage, processing of data and information, 80% in network plays a pivotal role. They are for the client computer providing various kinds of service of high performance computer, its main performance at high speed of operation ability, long and reliable operation, strong external data throughput capacity, etc. The server computer and ordinary, also have processor, hard disk, memory, and the system bus, but because it is according to specific network applications, specifically in handling capacity and microcomputer server, stability, reliability, security, expansibility, managerial etc exist differences, (2) Workstation: Workstation, English is a Workstation, personal computers and distributed computing basis, mainly for professional fields of application, with a powerful data and graph, image processing capacity to meet engineering design, animation, scientific research, software development, financial management, information service, professional field simulation and design of high performance computer. It belongs to a kind of high-grade computer screen display, generally have larger and larger amounts of memory and disk, also have strong information processing function and high-performance graphics, image processing function and networking, (3) : the English name Desktop Desktop thing, also called Desktop machine, is now very popular, the majority of micro computer at home and company with machines are desktops. Desktop notebook computer is relatively better performance, (4) Laptop: laptops English Notebook Computer, or Laptop NB (hereinafter referred to as Laptop computers, also called or Laptop (HongKong is called the Laptop computers), is a small, portable PC, usually heavy 1-3 kilograms. It and desktop framework, but provides a better portability: including LCD, smaller and lighter weight what. Notebook computer keyboard, but also provides the touch panel (TouchPad) or touch points (what), Pointing to offer better positioning and input function. Notebook computers can roughly divided into 4 categories: business model, fashion, multimedia applications, special purpose. Business laptops generally can be summarized as mobile, batteries, commercial software 3000ibs more, Fashionable vogue female type mainly aimed at the appearance, Multimedia application laptop computers have strong ability of graphics, image processing and multimedia capability, especially for the ability to play, XiangShouXing products. But, multimedia notebook computer has many strong independent graphics and sound card (hd), and support large screen, Special purpose is to serve the notebook computer professionals, can be in heat, cold, depression and war harsh environment, some is the use of the Olympic Games, such as heavy HuaShuo Everest base IT on "service" use HuaShuo notebook computer, (5) hand-held devices: hand-held devices in English, kinds, called Handheld PDA, SmartPhone, such as mobile phone, 3G phones, intelligent Netbook EeePC, etc, they feature is small. With the arrival of the era of 3G, handheld devices will gain greater development, its function will become stronger and stronger. Change is unchanging truth, as the changes of The Times, some ideas need to abandon, some standard redefined. Today we re-examine the classification standard, computer us to better understand the computer, and using the computers.
