In today's digital age, where visual content reigns supreme, crafting a compelling video introduction has become a crucial skill. Whether you're introducing yourself, a product, or an idea, a well-executed video introduction can captivate your audience from the very beginning. Inthis essay, we'll delve into the essential elements and techniques for creating an engaging video introduction.First and foremost, clarity and conciseness are paramount. Your video introduction should clearly communicate who you are or what your content is aboutwithin the first few seconds. This initial hook is crucial for grabbing viewers' attention and enticing them to continue watching. Avoid lengthy introductions or excessive background information that may bore or confuse your audience.Next, consider the tone and style of your introduction. Are you aiming for a professional and polished tone, or do you want to inject some personality and humor? The tone should align with your overall message and target audience. For example, a corporate presentation may require a more formal tone, while a personal vlog can afford to be more casual and conversational.Visual appeal is another key aspect of a successful video introduction. Pay attention to factors such as lighting, framing, and background scenery to create a visually pleasing environment. Additionally, consider incorporating dynamic visuals or animations to add interest and reinforce your message. However, avoid overwhelming the viewer with excessive effects that detract from the content itself.Furthermore, storytelling can elevate your video introduction to new heights. Humans are naturally drawn to narratives, so weaving a compelling story into your introduction can help establish an emotional connection with your audience. Whether it's recounting a personalanecdote, illustrating a problem and its solution, or showcasing a journey of growth, storytelling adds depth and resonance to your message.Moreover, interactivity can enhance viewer engagement and retention. Consider incorporating interactive elements such as polls, quizzes, or clickable links within your video introduction to encourage viewer participation and interaction. This not only keeps viewers actively engaged but also provides valuable insights into their preferences and interests.In addition to the content itself, technical quality is crucial for a professional-looking video introduction. Invest in high-quality equipment, such as a good camera, microphone, and editing software, to ensure crisp audio and clear visuals. Take the time to edit your video meticulously, removing any distractions or errors that may detract from the overall impact.Lastly, don't underestimate the power of practice and feedback. Before finalizing your video introduction,rehearse your script multiple times to refine your delivery and timing. Additionally, seek feedback from friends, colleagues, or online communities to gain valuable insights and perspectives. Constructive criticism can help you identify areas for improvement and polish your introduction to perfection.In conclusion, crafting an effective video introduction requires careful planning, creativity, and attention to detail. By focusing on clarity, tone, visual appeal, storytelling, interactivity, technical quality, and feedback, you can create a video introduction that captivates your audience and leaves a lasting impression. So, whether you're a content creator, entrepreneur, or educator, embrace the art of video introductions and unlock new opportunities for connection and engagement.。

ROM chips are not volatile and cannot be changed by the user.CMOS chips provides flexibility and expandability for a computersystem.It contains essential information that is required every time the computer system is turned on.It is powered by a battery and does not lose its contents when the power is turned.Its contents can be changed to reflect changes in the computer system.4.Five expansion cards are:graphics cards,sound cards,modem cards,NIC and TV tuner cards.Graphics cards connect the system board to the computer’s monitor,they convert the internal electronic sighals to video signals so they can be displayed on the monitor.Sound cards accept audio input from a microphone and convert it into a form that can be processed by the computer,they also convert internal electronic signals to audio signals.Modem cards allow distant computers to communicate with one another by converting electronic signals from within the system unit into electronic signals that can travel over telephone lines and other types of connections.NIC are used to connect a computer to one or more other computers.TV tuner cards can changes the TV signal into one that can be displayed on you monitor.5.Four standard ports are:serial ports,parallel ports, universal serial bus ports and firewire ports.Serial ports are often used to connect a mouse,keyboard,modem,and many other devices to the system unit.Parallel portsa are used to connect external devices that need to send or receive a lot of data over a short distance.USB ports are gradually replacing serial and parallel ports.FireWire ports provide connections to specialized FireWire devices .Chapter 7Crossword Puzzledot pitch keyboard wheel botton mechanical dumb omr refresh rate dpi webcam digital camera toggle printer joystick hdtv upcpixel flexible Multiple Choice1. a 2b 3a 4b 5d 6a 7d 8c 9d 10bMathing1.I 2e 3f 4j5a 6b 7g 8d 9c 10hOpen-Ended1.Input is any data or instructions that are used by a computer.Input devices are hardware usedto translate what people understand into a form that computers can process.2.①There are a widely of different pointing devices including the mouse,joystick,touchscreen,light pen,and stylus.A mouse controls a pointer that is displayed on the monitor.A joystick is the most popular input device for computer games.Y ou control game actions byvarying the pressure,speed,and direction of the joystick.A touch screen is a particular kind of monitor with a clear plastic outer layer.A light pen is a light-sensitive pen-like device.A stylus acts with the computer through handwriting recognition software.②There are three types of scanning devices:optical scanners,card readers,bar code readers,andcharacter and mark recognition devices.An optical scanner accepts documents consisting of text and/or images and converts them to machine readable form.Card readers interpret encoded information.Bar code readers are either handheld wand readers or platform scanners.Character and mark recognition devices are scanners that are able to recognize special characters and marks.③Image capturing devices include digital cameras and digital video cameras.Digital cameras capture still images.Digital video cameras capture motion.④Audio input can take many forms including the human voice and music.V oice recognition systems accept voice commands to control computer operations and to create document.MIDI is a standard for connecting musical instruments to the system unit.3.The most widely used output devices are monitors,printers and audio output.Monitors present visual images of text and graphics.Printers translate information that has been processed by the system unit and present the information on paper.Audio output devices translate audio information from the computer into sounds that people can understand.4. Output is processed data or information.Output devices are hardware used to translateinformation that has been processed by the system unit into a form that humans can understands.5. Devices combines features of input devices such as scanners with features of output deviceslike printers are called combination input and output devices.Combination devices include fax machines,multifunction devices,Internet telephones,and terminals.A fax machine is a standard tool in nearly every office.Multifunction devices combine the capabilities of a scanner,printer,fax,and copying machine.Internet telephone are specialized input and output devices for receiving and sending voice communication.Terminals are input and output device that connect you to a mainframe or other type of computer.Chapter 8Crossword PuzzleTrack Raid access time pits and lands disk caching online storage sector floppy zip cylinder densityMultiple Choice1. a 2a 3c 4a 5c 6a 7c 8d 9d 10cMatching1.g 2a 3j 4i 5d 6b 7h 8c 9f 10eOpen-Ended1.The traditional floppy disk is the 1.44MB 3-inch disk.They have a thin exterior jacker madeof hard plastic to protect the flexible disk inside.The high capacity floppy disks are 3 inches in diameter.They are able to store more information,are thicker,and require special disk drives.2.There are three types of hard disks:internal hard disk,hard-disk cartridge,and hard-disk pack.Three ways to improve the performance of hard disks are disk caching,redundant arrays of inexpensive disks,and file compression/decompression.Disk caching improves hard-disk performance by anticipating data needs.Redundant arrays of inexpensive disks improve performance by expending external storage,improving access speed,and providing reliable storage.File compression and file decompression increase storage capacity by reducing the amount of space required to store data and programs.3.The two most common optical disc formats are CD and DVD.Hi def is the next generation ofoptical discs.①There are four basic types of CDs:read only,write once,rewritable,and Picture and PhotoCDs.Read only CDs cannot be written on or erased by the users,they are used to distribute large databases , references ,and large software application packages.Write once CDs can be written to once,they are used to archive data and to record music download from the Internet.Rewritable CDs are similar to write once CDs except that the disks surface is not permanently altered when data is recorded.Picture and Photo CDs use a special format developed by Eastman Kodak to store digital images.②There are three types of DVDs :read only,write once,and rewriteable.Read only DVDs can provide over two hours of very high-quality video and sound comparable to that found in motion picture theatres.Write once DVDs are typically used to create permanent archives for large amounts of data and to record videos.Rewriteable DVDs are competing rewriteable formats.4.Solid-state storage does not have moving parts.Internet drives use the Internet to store dataand information.Magnetic tape provides sequential access for backup.Solid-state storage is more expensive than the others,it is more reliable and requires less power.Internet drives are low cost and the flexibility to access information from any location using the Internet.Access speed is slower.Magnetic tapes provide slower sequential access.It is an effective and commonly used tool for backing up data.5.Mass storage refers to the storage of large amounts of data in a persisting andmachine-readable fashion. Enterprise storage systems are the computer storage systems designed for large-scale, high-technology environments of the modern enterprises.Mass storage Devices have been described as mass storage include tape libraries, RAID systems, hard disk drives, magnetic tape drives, optical disc drives, magneto-optical disc drives, drum memory, floppy disk drives, punched tape and holographic memoryChapter 9Crossword PuzzleClient bus network network gateway modulation base station packets analog gps topology nic bps Bluetooth Node Bandwidth Dsl hubMultiple Choice1. c 2b 3a 4d 5c 6d 7b 8b 9b 10dMatching1.g 2b 3a 4i 5h 6e 7c 8j 9d 10fOpen-Ended1.①Connectivity is a concept related to using computer networks to link people and resources.②The single most dramatic change in connectivity and communications in the past five yearshas been the widespread use of mobile or wireless telephones.This wireless technology allows individuals to stay connected with one another from almost anywhere at any time,the revolution is just beginning.③Communication systems transmit data from one location to another.Every communicationsystem has four basic elements:sending and receiving devices,communication channel,connection devices,and data transmission specifications.2.①Physical connections use a solid medium to connect sending and receiving devices.These connections include telephone lines,coaxial cable,and fiber-optic cables.Telephone lines consist of twisted pair cable,they have been the standard transmission medium for years for both voice and data.Coaxial cable replaces the multiple wires of telephone lines with a single solid-copper core.Fiber-optic cable transmits data as pulses of light through tiny tubes of glass.②Wireless connections use the air to connect sending and receiving devices.Primary technologies used for wireless connections are infrared,boardcast radio,microwave, and satellite.Infrared uses infrared light waves to communicate over short distances.Broadcast radio communication uses special sending and receiving towers called transceivers.Microwave communication uses high-frequency radio waves.Satellite communication uses sstellites orbiting about 22000 miles above the earth as microwave relay stations.3.The standard protocol for the Internet is TCP/IP.The essential features of this protocolinvolve:identifying sending and receiving devices and reformatting information for transmission across the Internet.Identification:Every computer on the Internet has a unique number address called an IP address,the Internet uses IP addresses to deliver e-mail and to locate Web sites.Reformatting:Information sent or transmitted across the Internet usually travels through numerous interconnected networks.Before the massage is sent,it is reformatted or broken down into small parts called packets,at the receiving end,the packets are reassembled into the correct order.4.The four principal network topologies are star,bus,ring,and hierarchical.In a star network,a number of small computers or peripheral devices are linked to a central unit,all communications pass through this central unit.In a bus network, each device in the network handles its own communication control.In a ring network,each device is connected to two other devices,forming a ring.The hierarchical network consists of several computers linked to a central host computer,other computers are also hosts to other,smaller computers or to peripheral devices.5.The most common network strategies are terminal,client/server,and peer-to-peer systems.①In a terminal network system,processing power is centralized in one large computer.For theend user it is lack of control and flexibility.②Client/server network system use one computer to coordinate and supply services to othernodes on the network.The abiligy of powerful network management software to monitor and control network activities.③In a peer-to-peer network system,nodes have equal anthority and can act as both clients andservers.The networks are inexpensive and easy to install, and they usually work well for smaller systems with fewer than 10 nodes.Chapter 10Crossword PuzzleCookie surge protector mal ware ergononics cracker keystroke logger snoopware hacker history fileMultiple Choice1. a 2a 3d 4b 5a 6c 7d 8c 9b 10dMatching1.g 2h 3f 4a 5b 6c 7j 8d 9i 10eOpen-Endedrge databases raise some serious concerns on privacy:identity theft and mistaken identity.The impact of private networks on privacy have the two parts:The first instance,of firmseavesdropping on employees,has inspired attempts at federal legislation.The second instance,in which online information services screen and reject messages,is a common activity with most commercial services.The internet brings illusion of anonymity,the web creates a history file ,your web activity is monitored is by cookies. To respond to these privacy concerns, a code of fair information practice has been established.2. Computer criminals are of five types:Employees:The largest category of computer criminals consists of those with the easiest access to computers-namely,employees.Outside users:Some suppliers or clients may have access to a company’s computer system.Hackers and crackers:Hackers are people who gain unauthorized access to a computer system for the fun and challenge of it.Crackers do the same thing but for malicious purposes.Organized crime:Members of organized crime groups have discovered that they can use computers just as people in legitimate businesses do,but for illegal purpose.Terrorists:Knowledgeable terrorist groups and hostile governments could potentially crash satellites and wage economic warfare by disrupting navigation and communication systems.3. Some of the principal measures to protect computer security are encryption,restrictingaccess,anticipating disasters,and backing up data.Encryption is the conversion of data into a form, called a ciphertext, that cannot be easily understood by unauthorized people.Corporations have use it for years that some law enforcement agencies are unable to wiretap messages from suspected criminals.Individuals are also using encryption programs to safeguard their private communications.4.Ergonomics is defined as the study of human factors related to things people use.The physical health matters related to computers that have received the most attention recently are the following:eyestrain and headache,back and neck pain,and repetitive strain puter technology creates some irritants that may be counterproductive:noise,and electronic monitoring.5.The basic elements of the Green PC are:System unit ,display, and manufacturing.As a computer user,you can do to help protect the environment are the following:conserve, recycle ,and educate.期末考试题型如下：1. 名词缩写（英文）2. 填空（中文）3. 选择（英文）4. 连线（英文）5. 计算（中文）6. 简答（中文）。
