Computer programs have undergone many changes during this time in response to user need and advances in technology. Newer ideas in computing such as parallel computing, distributed computing, and artificial intelligence, have radically altered the traditional concepts that once determined program form and function. In parallelcomputing parts of a problem are worked on simultaneously by different processors, and this speed up the solution of the problem. Another type of parallel computing called distributed computing use CPUs from many interconnected computers to solve problems. Research into artificial intelligence (AI) has led to several other new styles of programming.2.High-level languages are commonly classified asprocedure-oriented, functional, objected-oriented, logic languages. The most common high-level languages today are procedure-oriented languages. In these languages, one or more related blocks of statements that perform some complete function are grouped together into a program module, or procedure, and given a name such as “procedure A”. If the same sequence of operations is needed elsewhere in the program, a simple statement can be used to refer back to the procedure. In essence, a procedure is just a mini-program. A large program can be constructed by grouping together procedures that perform different tasks.四、汉译英题（20分）最著名的互联网例子是因特网。

计算机专业英语作业
计算机专业英语作业：1、请将视频“什么是电脑硬件”中所述内容用英文表示。
2、请将以下英文翻译为中文。
1）Plug and Play, sometimes, abbreviated PnP, is a catchy phrase used to describe devices that work with a computer system as soon as they are connected. The user does not have to manually install drivers for the device or even tell the computer that a new device has been added. Instead the computer automatically recognizes the device, loads new drivers for the hardware if needed, and begins to work with the newly connected device.For example, if you connect a Plug-and-Play mouse to the USB port on your computer, it will begin to work within a few seconds of being plugged in. A non plug-and-play device would require you to go through several steps of installing drivers and setting up the device before it would work.While Plug and Play usually refers to computer peripheral devices, such as keyboards and mice, it can also be used to describe internal hardware. For example, a video card or hard drive may be a Plug and Play device, meaning the computer will recognize it as soon as it is installed. The only difference is that internal components usually require the computer to be turned off when they are installed, while external devices can typically be installed while the computer is running.2）What are some examples of computer peripheral devices?Answer:⏹ A computer peripheral, or peripheral device, is an external object that provides input and output for the computer.⏹Some common input devices include: keyboard, mouse, joystick, pen tablet, MIDI keyboard (musical instrument digital interface数码音响), scanner, digital camera, video camera, microphone.⏹Some common output devices include: monitor, projector, TV screen, printer, plotter, speakers.⏹There are also devices that function as both input and output devices, such as: external hard drives, media card readers, digital camcorders, digital mixers, MIDI equipment.⏹While these are some of the more common peripherals, there are many other kinds as well. Just remember that any external device that provides input to the computer or receives output from the computer is considered a peripheral.3）Binary is a two-digit (Base-2) numerical system, which computers use to store data and compute functions. The reason computers use the binary system is because digital switches inside the computer can only be set to either on or off, which are represented by a 1 or 0. Though the binary system consists of only ones and zeros, the two digits can be used to represent any number.4）There are many types of compact disks. One format is called CD-RWs. They can be recorded on and re-recorded on (rewritten on) as you would do with a floppy disk. Another format is the CD-ROM. The technology for recording on these disks is different form other CDs.5）Stands for "Read-Only Memory." Please do not confuse this term with RAM or a hard drive, as many people already do. ROM is memory containing hardwired instructions that the computer uses when it boots up, before the system software loads. In PCs, the instructions are read from a small program in the ROM, called the BIOS (Basic Input/Output System).6）disk driveA machine that reads data from and writes data onto a disk. A disk drive rotates the disk very fast and has one or more heads that read and write data. There are different types of disk drives for different types of disks. For example, a hard disk drive (HDD) reads and writes hard disks, and a floppy drive (FDD) accesses floppy disks. A magnetic disk drive reads magnetic disks, and an optical drive reads optical disks. Disk drives can be either internal (housed within the computer) or external (housed in a separate box that connects to the computer). Disk drives can be either internal (housed within the computer) or external (housed in a separate box that connects to the computer).7）removable disktype of disk drive in which hard disks are enclosed in plastic or metal cartridges so that they can be removed like floppy disks. Removable disk drives combine the best aspects of hard and floppy disks. They are nearly as capacious and fast as hard disks and have the portability of floppy disks. Their biggest drawback is that they're relatively expensive.8）serial portA port, or interface, that can be used for serial communication, in which only 1 bit is transmitted at a time. A serial port is a general-purpose interface that can be used for almost any type of device, including modems, mice, and printers (although most printers are connected to a parallel port).9）parallel portA parallel interface for connecting an external device such as a printer. Most personalcomputers have both a parallel port and at least one serial port.10）Pseudocode (derived from pseudo and code) is a compact and informal high-level description of a computer programming algorithm that uses the structural conventions of some programming language, but typically omits details that are not essential for the understanding of the algorithm, such as subroutines, variable declarations and system-specific code.11）2.5 Using Function KeysYour computer has 12 function keys, F1 through F12. The functions assigned to these keys differ for each application. You should refer to you software documentation to find out how these keys are used.The [FN] key provides extended functions for the notebook and is always used inconjunction with another key.Fn+F1 SleepThis function will put the E1245 notebook into sleep mode. The LCD will switch off and devices will switch to lower power mode.Fn+F2 Fan ControlThis function will enable or disable the Silent Fan function . This will enable the user to put the fan into quiet mode if the user needs the notebook o be quieter.Fn+F3 Mute V olumeThis function will mute the volume control in Windows and all sound output from the speakers will stop. Pressing this combination again will enable sound output.Fn+F4 LCD/Display-Out SwitchThis function will switch the display configuration for the E1425 -It will cycle between 3 modes depending on operation system settings. These 3 Modes are:LCD Only-Image on the E1425 LCDDisplay Only-Image on external monitorLCD+Display-Image on LCD and external monitor12）课本P89 EX.5 把下列短文翻译成中文。

The term coder is used to describe . 4. In order to solve a computational problem, you can let a person or a to do it. Passage C The Internet, then known as ARPANET, was brought online in 1969, which initially connected four major computers at universities in the southwestern US . The early Internet was used by computer experts , engineers, scientists, and librarians. There was nothing friendly about it. There were no home or office personal computers in those days, and anyone who used whether a computer professional or an engineer or scientist or librarian, had to learn to use a very complex system. The Internet matured in the 1970's as a result of the TCP/IP architecture. As the commands for E-mail, FTP , and te were standardized, it became a lot easier for non-technical people to learn to use the nets. It was not easy by today' s standa by any means, but it did open up use of the Internet to many more people in universities in particular. Other departments besides the libraries, computer, physics, and engineering departments found ways to make good use of the nets -- to communicate with colleagues around the world and to share files and resources. In 1991, the first really friendly interface to the Internet was developed at the University of Minnesota. The University wanted to develop a simple menu system to access files and information on campus through their local network. Since the Internet was initially funded by the government, it was originally limited to research, education, and governme uses. Commercial uses were prohibited unless they directly served the goals of research and education. This policy continued until the early 1990's, when independent commercial networks began to grow.

DNS stands for Domain Name ___________.答案: System3. 简答题1. What is the difference between TCP and UDP?答案: TCP (Transmission Control Protocol) is a connection-oriented protocol, which means it establishes a connection between the sender and receiver before transferring data. It ensures that all packets are received in the correct order and provides error checking. UDP (User Datagram Protocol), on the other hand, is a connectionless protocol that does not establish a direct connection before transmitting data. It does not guarantee packet delivery or order but is faster and more efficient for time-sensitive applications.2. What is the purpose of an operating system?答案: An operating system (OS) is a software that manages computer hardware and software resources and provides common services forcomputer programs. Its primary purpose is to enable the user to interact with the computer and provide a platform for running applications. It manages memory, file systems, input/output devices, and multitasking. The OS also handles system security and resource allocation to ensure optimal performance.4. 解答题请参考下文并给出自己的解答。

In fact, if you can see their internals of computers, You will find that they all have the basic parts,the haddwares,do large part of the works in the computers.to explan,let’s look at some things you know ,like a house.what a great thing in the house is you have full space to put all the iterms.in fact ,many houses have basements.The basement is a good place to store debris.Basement, the more you can store.The same principle applies to computers.We need not boxes and bicycles, but photos, music, documents and plete this task in the computer hard drive rather than in the basement, a computer hard drive, holds all your files will be used later, like basements, like the larger hard drive, the more things you can store. Basement is not perfect, going to the basement to take the things you need to spend much time, maybe put a cupboard on the ground floor can help you solve this problem, you can quickly get the items you want, although the cabinet can not put too many items, at least you do not always go to the basement, in the computer too, The computer can not quickly access to the data stored in the hard disk, because the computer go a long way to gain access to the hard disk data. In the computer memory (RAM) is like a cupboard, RAM's full name is called [random access memory], which allows the computer to access data more quickly and, of course, it also means that the operation of RAM to make your computer faster , but this cupboard (RAM) has a drawback, the memory will be cleared of stored data When every time you restart, of course, to make the house a variety of household appliances can operate at the appropriate time, you must have an Explorer to help you manage these appliances, if the weather is too hot , you maybe need to open the air conditioner to adjust the temperature, when it is dark, you need to turn on the lights. Computers, too, must have a bit Explorer to ensure that all other parts are functioning properly, the Explorer is the processor (CPU), small size of the processor, like a computer exclusive (in charge), it will send and receive information and to assist the software to complete the work. The faster the processor, the faster execution speed of the computer would be, so, let us revisit. Hard drive, like a basement, it can store the information you need. Memory, like a cupboard, which can increase data access speed. Processor, like the Field Explorer, always able to complete the work that we deliver, but also to ensure the normal operation of the various parts. Next time, when you use the computer, think about plain English in the host computer's computer hardware what happened, the various parts of computer hardware complement each other, to help you do all the things I Common Craft's Lee LeFever, "Computer hardware of Plaining English "The film recorded by me, if you need a higher quality video, or need to use the authorization of the film, please contact me website.2、请将以下英文翻译为中文。

网址一：/hub/save-computer-from-Hackers网址二：/hub/What-is-Phishing姓名：**学号：************分校：通州（一）原文1.What is Computer Hacking?Computer hacking is a malicious act, so it is important for your computer and data to protect from Hacking. Computer Hacking refers to the process of making malicious modifications to a software or hardware to accomplish an aim outside the original creator's objective. Hackers are usually expert programmers who usually see hacking as a real life application of their skills.Hacking has become a nuisance in recent times and the protection from hacking has become more complex. Infact, the hackers have become so good that even the software giants are feeling a headache. Nintendo recently reported a loss of $975 million due to privacy and Microsoft has lost an estimated $900 million in five years.Well, the Giants are not the only targets of these hackers, even common individuals are not safe. The dangers range from little thefts to sponsored terrorism. These include stealing personal information and spying your activities. They can get to your secrets and destroy your credit. The dangers are possibly endless.How to protect from HackingPrevention is Better Than Cure. The problem of computer hacking has become really serious. But there are some basic methods which are usually the best to guarantee a Hacker-free system. Here, I am going to introduce some basic tips to save your computer and data from hackers.Using Antivirus SoftwareAntivirus software are one of the basic tools for your data and computer to protect from hacking. Antivirus software act as a protecting net that catches any potential threat before it reaches your system. They can prevent unauthorized access to your computer, protects your system from viruses and cloaks your data ports from intruders searching for any opening. The dangers range from little thefts to sponsored terrorism. These include stealing personal information and spying your activities.Nowadays anti virus software are completely automated. Go for the best when choosing anti virus software and make sure that you scan your system for viruses atleast once a week. Norton antivirus from Symantecis one of the leading products in the industry. Avastis another great antivirus tool to protect from hacking.Using FirewallWhat is a Firewall?A firewall is a set of programs located at the network gateway server which protects a private network from unauthorized access from other networks. The term firewall is originally referred to a wall intended to confine a fire.A firewall protects your computer from offensive websites and potential hackers. It keeps your data and information safe from unwanted intruders. Firewalls are designed to prevent unauthorized access to your network, much like a locked door.Thus firewall is a vital tool for your strategy against hackers so don't forget to set up one for your system. Microsoft has a built-in firewall software but you can also try the Symantec firewall.Using Anti Spyware SoftwareWhat is a Spyware?A spyware is a self installing software which secretly gathers information about a person's computing activities such as surfing habits and viewed sites. Spywares are truly a hacker's tool, not only collecting personal information but also interfering with user control by installing additional software and redirecting web browsers.Anti spyware software are designed to save your computer from hackers. They not only protect your computer by detection and removal of spywares but also preventing automatic installation of these malicious programs. Spysweeperis a great anti spyware software to guarantee a spyware free computer.Email SecurityEmail is one of the leading hacker's tools. Hackers use emails to transmit malicious software to your computer. Emails are usually very cheap which gives the hackers loads of opportunities. One of the basic tips to prevent hacking is to be extra careful with emails. The most important tip is that you should never hand out your real email address to a stranger. Never open an email arriving from an unknown source and never try to open an attachment with an email if you don't know the sender. Aviraantivirus is a useful tool to filter your emails for potential threats as well as provide premium protection for your computer.Software updatesHackers are always searching for security gaps in your system. Anti virus and anti spyware software usually lose their effectiveness with time as new and more advanced malicious programs are created by hackers.Its important to go for the latest security software in the market to guaranteemaximum security from threats. Make sure you frequently check out for software updates or set your software to update automatically.Internet SecurityBeing extra careful while surfing is the best way to protect your computer from hackers. Simple precautions can mean the difference between a secure and vulnerable system. A great way to save yourself from hackers is to avoid visiting hacker controlled sites usually committed to porn, free downloads and online gaming. Also be extra careful while downloading something from an unknown source. Never ignore a security warning about a site. Its better to be safe than sorry.Educate YourselfWhen working for an offensive against hackers, the most important step is to educate yourself. Hacking is a dynamic topic with developments arising every moment. Hackers are intelligent and innovative and you should be prepared for it.Computers are vulnerable. No matter what you do, its impossible to be 100% save. Important data like personal detail and credit card information should never be saved directly on a computer. A password protector is a great way to protect this data.Another great way to secure your computer is to use a password on your computer. Well, it can't really save you if your computer gets stolen (in case of a laptop) but can save you from unauthorized people who can reach to your computer.Windows updateMicrosoft Windows is the best OS which comes with almost all the tools to protect you and your computer from hacking. To make the most of this, it is important to keep your windows updated. An easy way to do this is by checking for updates at Microsoft Windows Update. You can also set your windows security software to check for updates automatically so you don't miss anything. ...2. What is a Phishing Attack?Identity theft has become the new white collar crime and it has grown tremendously. Criminals that steal identities use them in a number of ways. One of the most common tricks is to use a stolen identity to open a line of credit. The line of credit is then depleted by the thief and the actual person receives the bill. Identities are also stolen for malicious intent, such as stealing a military officer’s email credentials in hopes of carrying out fictitious orders to troops.Phishing is a relatively new term to describe ploys used by criminals trying to steal identities. Phishing scams are on the rise:"During 2004, close to 2 million U. S. citizens had their checking accounts raided by cyber-criminals. With the average reported loss per incident estimated at $1200, total losses were close to $2 billion. The incidence of phishing e-mails―e-mails thatattempt to steal a consumer’s user name and password by imitating e-mail from a legitimate financial institution –has risen 4,000 percent over the past six months."•What is Phishing VideoThe term “phishing” is based on the term “fishing”. With fishing you bait a hook and try to catch fish. If you do not receive a bite, you often change the type of bait until you start catching fish. With phishing, the bait is typically an email that appears legitimate. The email typically asks for a bank customer to validate their information, however, the email redirects the customer to a fictitious bank site made to look like the legitimate bank site (James, 2005). The criminals hope the customer will not notice the redirected bank site is fictitious and that they will validate their account information. There are numerous phishing emails used as bait and criminals hope the more bait they use, the greater chances someone will fall for the scam.The key to preventing identity theft is awareness. Financial institutions typically do not ask for account information validation. Any emails that ask for account validation or social security numbers, should be validated. The link contained within the email can be checked for legitimacy. These links often go to bogus sites that can easily be determined by the website link. For example, if you bank at and you receive an email that has a link and takes you to .customer.cz, this should raise suspicion. Phishing scams not only use email, but the telephone is also used. A typical scam involves a telephone call with someone impersonating your credit card company and asking you to validate your social security number, date of birth, etc. Credit card companies already have this information and do not need you to validate it. A simple line of defense is to ask the caller for the credit card company’s number and call them back。

Computer programs have undergone many changes during this time in response to user need and advances in technology. Newer ideas in computing such as parallel computing, distributedcomputing, and artificial intelligence, have radically altered the traditional concepts that once determined program form and function. In parallel computing parts of a problem are worked on simultaneously by different processors, and this speed up the solution of the problem. Another type of parallel computing called distributed computing use CPUs from many interconnected computers to solve problems.Research into artificial intelligence (AI) has led to several other new styles of programming.2.High-level languages are commonly classified asprocedure-oriented, functional, objected-oriented, logic languages. The most common high-level languages today are procedure-oriented languages. In these languages, one or more related blocks of statements that perform some complete function are grouped together into a program module, or procedure, and given a name such as “procedure A”. If the same sequence of operations is needed elsewhere in the program, a simple statement can be used to refer back to the procedure. In essence, a procedure is just a mini-program. A large program can be constructed by grouping together procedures that perform different tasks.四、汉译英题（20分）最著名的互联网例子是因特网。

These parts are interconnected by buses, often made of groups of wires. Inside each of these parts are trillions of small electrical circuits which can be turned off or on by means of an electronic switch. Each circuit represents a bit (binary digit) of information so that when the circuit is on it represents a “1”, and when off it represents a “0” (in positive logic representation). The Circuits are arranged in logic gates so that one or more of the circuits may control the state of one or more of the other circuits.The control unit, ALU, registers, and basic I/O (and often other hardware closely linked with these) are collectively known as a central processing unit (CPU). Early CPUs were composed of many separate components but since the mid-1970s CUPs have typically been constructed on a single integrated circuit called a microprocessor.The control unit (often called a control system or central controller) manages the computer’s various components; it reads and interprets, (decodes) the program instructions, transforming them into a series of control signals which activate other parts of the computer. Control systems in advanced computers may change the order ofsome instructions so as to improve performance.(1)、A general purpose computer has four main components: the arithmetic logic unit, the control unit, ________, and the input and output devices.正确答案：B(2)、If the circuit is on, it represents a ________(in positive logic representatio n).正确答案：A(3)、The central processing unit is composed of ________ components.正确答案：C(4)、the control unit can not _________.the program instructions.the program instructions into a series of contr ol signals.the program instructions.正确答案：C(5)、The control unit is called _________.central systemCPUcontrol circuit正确答案：D。

You should not confuse processor’s instruction set with the instructions found in high—level programming languages,such as BASIC or PASCAL.An instruction is made up of operations that specify the function to be performed and operands that represent the data to be operated on.For example,if an instruction is to perform the operation of adding two numbers,it must know what the two numbers are and where the two numbers are.When the numbers are stored in the computer’s memory,they have an address to indicate where they are, so if an operand refers to data in the computer’s memory it is called an address.The processor’s job is to retrieve instructions and operands from memory and to perform each operation.Having done that,it signals memory to send it the next instruction.This step-by-step operation is repeated over and over again at awesome speed.A timercalled a clock releases precisely timed electrical signals that provide a regular pulse for the processor’s work.The term that is used to measure the comput er’s speed is borrowed from the domain of electrical engineering and is called a megahertz(MHz,which means million cycles per second.A processor is composed of two functional units——a control unit and an arithmetic/logic unit——and a set of special work spaces called registers.。
