A clean water source, water is not contaminated. To have a reliable power supply, not only to maintain normal lighting,Ever since the advent of computers, there have been constant changes. 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. Computers become even more effective when connected to other computers in a network so users can share information.计算机系统包括计算机、外围设备和软件。

计算机英语实用教程第三版课后练习题含答案

计算机英语实用教程第三版课后练习题含答案第一章练习题答案1. What is the difference between a CPU and a GPU?A CPU (Central Processing Unit) is a general-purpose processor that performs tasks that require complex arithmetic and logical operations. A GPU (Graphics Processing Unit), on the other hand, is a specialized processor that is designed to handle tasks that involve highly parallelizable computations, such as those required for rendering graphics.2. What is the difference between RAM and ROM?RAM (Random Access Memory) is a type of memory that stores data temporarily while the computer is running. RAM is volatile, meaning that its contents are erased when the computer is turned off. ROM (Read-Only Memory), on the other hand, is a type of memory that stores data permanently, even when the computer is turned off. ROM is non-volatile, meaning that its contents are retned even when there is no power.3. What is the difference between a bit and a byte?A bit is the smallest unit of digital information, represented by a binary digit (0 or 1). A byte, on the other hand, is a unit of digital information that consists of eight bits. Bytes are commonly used to represent characters, such as letters and numbers.4. What is the purpose of an operating system?An operating system (OS) is a software program that manages the resources of a computer, including the CPU, memory, storage, and devices such as printers and displays. The purpose of an operating system is to provide an environment in which applications can run and interact with the hardware without directly accessing the underlying hardware.5. What is the difference between a compiler and an interpreter?A compiler is a program that translates the source code of a program into executable code that can be run on a specific computer platform. The resulting executable code can be run multiple times without the need for recompilation. An interpreter, on the other hand, is a program that reads and executes source code instructions one at a time. Interpreted code is typically slower than compiled code, but does not require the extra step of compilation before it can be run.第二章练习题答案1. What is the difference between a LAN and a WAN?A LAN (Local Area Network) is a network that connects computers and other devices that are located in the same physical location, such as an office building or a home. A WAN (Wide Area Network), on the other hand, is a network that connects computers and other devices that are located in different physical locations, often separated by vast distances.2. What is a router and how does it work?A router is a device that connects two or more networks together and forwards data between them. Routers use routing tables to determine thebest path for data to take between networks, and use protocols such as TCP/IP to communicate with other devices on the network.3. What is the difference between TCP and UDP?TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are both protocols used for transmitting data over the internet. TCP is a connection-oriented protocol, which means that it establishes avirtual circuit between two endpoints over which data can be transmitted. TCP uses error correction and flow control to ensure that data arrivesat its destination correctly and in the correct order. UDP, on the other hand, is a connectionless protocol that does not establish a virtual circuit between endpoints. UDP does not provide error correction or flow control, but is often used in situations where speed and simplicity are more important than reliability.4. What is a DNS server?A DNS (Domn Name System) server is a special type of server that translates domn names into IP addresses. When a user enters a domn name into their web browser, the browser sends a request to a DNS server to find the corresponding IP address for that domn name. The DNS serverthen returns the IP address to the browser, which can then connect tothe website.5. What is a firewall and how does it work?A firewall is a security device that is used to protect a networkfrom unauthorized access. Firewalls can be implemented as hardware or software, and typically work by examining incoming and outgoing network traffic and blocking any traffic that does not meet a set of predefinedrules. Firewalls can be configured to block specific types of traffic, such as traffic from certn IP addresses or traffic that uses a certn protocol. Firewalls can also be configured to allow or deny access to specific network resources based on user or device credentials.。

The system must first authenticate（验证）a user seeking access. Typically the authemiccition function determines whether the user is permitted to access the system at all. Then the access control function determines if the specific requested access by this user is permitted. A security administrator maintains an authorization（授权）d-sbase that specifies what type of access to which resources is allowed for this user. The access control function consults this database to detemine whether to grant access. An auditing function monitors and keeps a record of user accesses to system resources.In practice, a number of com—cmetus may cooperatively share the access control function.

Part3 Listening and SpeakingListening Comprehension1. B2. A3. DOriginalRoadrunnerOn the current TOP 500 list of worldwide supercomputers released in June 2008, Roadrunner, IBM's new super computer, is rated No.1, exceeding IBM Blue Gene, the former No.1 on the list. IBM calls Roadrunner the world’s first “hybrid” supercomputer. It combines 12,960 IBM Cell chips, which power Sony's PlayStation 3 video game machine, with 6,948 dual-core AMD Opteron chips and 80 terabytes of memory. It runs Red Hat Linux.Roadrunner is billed at the fastest in the world, operating at one petaflop or one thousand trillion calculations per second. So, exactly how fast is the supercomputer? IBM said the speed is roughly equivalent to the combined computing power of 100,000 of today's fastest laptop computers - users would need a stack of laptops 1.5 miles high to match Roadrunner's performance. It would also take the entire population of the earth - about 6 billion people - each working a handheld calculator at the rate of 1 second per calculation more than 46 years to do what Roadrunner can doin one day.IBM said that in the past 10 years, supercomputer power has increased about 1,000 times. Today, just three of Roadrunner's 3,456 tri-blade units have the same power as the 1998 fastest computer. Now, a complex physics calculation that will take Roadrunner one week to complete would have taken the 1998 machine 20 years to finish.Dictation1. twentieth century2. citizen3. mathematical4. early development5. career6. stored7. memory8. operate9. electronic 10. calculation 11. memories 12. manner 13. control unit 14. calculating unit 15. control unit 16. a piece of data 17. accordingly 18. advancement 19. architecture 20. majorityUnit 2Part1 Reading and TranslatingSection AⅠ. 1.

Fill in each of the blanks with one of the words given in the following list, making changes if necessary:We can define a computer as a device that accepts input, processes data, stores data, and produces output. According to the mode of processing, computers are either analog or digital. They can also be classified as mainframes, minicomputers, workstations, or microcomputers. All else (for example, the age of the machine) being equal, this categorization provides some indication of the computer’s speed, size, cost, and abilities.Ever since the advent of computers, there have been constant changes. First-generation computers of historic significance, such as UNIVAC (通用自动计算机), 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-scaleintegration 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: 计算机将变得更加先进，也将变得更加容易使用。
