First-generation computers of historic significance, such as UNIVAC, introduced in the early 1950s, were based on vacuum tubes. Second-generation computers, appearing in the early 1960s, were those in which transistors replaced vacuum tubes. In third-generation computers, dating from the 1960s, integrated circuits replaced transistors. In fourth-generation computers such as microcomputers, which first appeared in the mid-1970s, large-scale integration enabled thousands of circuits to be incorporated on one chip. Fifth-generation computers are expected to combine very-large-scale integration with sophisticated approaches to computing, including artificial intelligence and true distributed processing.IV(Translate the following passage from English into Chinese.A computer system includes a computer, peripheral(外围的)devices, and software.

Computer hardware in and of itself does not provide a particularly useful mind tool. To be useful, a computer requires a set of instructions, called software or a computer program, which tells the computer how to perform a particular task.

Unit 1 Text AExercisesI. Answer the following questions according to the text.1. The Internet of Things refers to uniquely identifiable objects (things) and their virtual representations in an Internet-like structure. The term Internet of Things was first used by Kevin Ashton in 1999.2. It stands for Radio-frequency identification. It is often seen as a prerequisite for the Internet of Things.3. Casagras is a global network infrastructure, linking physical and virtual objects through the exploitation of data capture and communication capabilities. This infrastructure includes existing and evolving Internet and network developments.4. In the IoT, physical and virtual ‘things’ have identities, physical attributes, and virtual personalities.5. The original idea of the Auto-ID Center is based on RFID-tags and unique identification through the Electronic Product Code.6. The next generation of Internet applications which use Internet Protocol Version 6 would be able to communicate with devices attached to virtually all human-made objects because of the extremely large address space of IPv6.7. In the future the Internet of Things may be a nondeterministic and open network in which auto-organized or intelligent entities (Web services, SOA components), virtual objects will be interoperable and able to act independently (pursuing their own objectives or shared ones) depending on the context, circumstances or environments. 8. Embedded intelligence can be more clearly defined as: leveraging the capacity to collect and analyze the digital traces left by people when interacting with widely deployed smart things to discover the knowledge about human life, environmentinteraction, as well as social connection/behavior.9. In an Internet of Things, the precise geographic location of a thing — and also the precise geographic dimensions of a thing — will be critical.10. Currently, Internet of Things frameworks seem to focus on real time data logging solutions like Pachube: offering some basis to work with many "things" and have them interact. Future developments might lead to specific software development environments to create the software to work with the hardware used in the Internet of Things.II.
