Many of the robots in use today do jobs that are especially difficult for human workers. These are the types of jobs that require great strength or pose danger. 1 ____. A welding tool used by a human worker weighs about 100 pounds or more and is difficult to handle. As mechanical supermen, robots may be called upon to do anything from moving heavy components between workstations on a factory floor to carrying bags of cement.

Spay painting is another task suited to robots because robots do not need to breathe. 2 ____. Robots are better at this task, not because they are faster or cheaper than humans, but because they work in a place where humans cannot.

Third in the list of useful jobs for robots is the assembly of electronic parts. Robots shine at installing chips in printed circuit boards because of a capability that robots have that people don’t. 3 ____. This automatic accuracy is particularly valuable in this kind of industry because locating and fixing mistakes is costly.

Earlier robots were usually blind and deaf but newer types of robots are fitted with video cameras and other sensing devices that can detect heat, texture, size, and sound. 4 ____.

In their efforts to expand the range of robotic applications, researchers are looking beyond traditional designs to examine a variety of potential models from the biological world. The industrial arm is a classic example. Scientists have been able to model robots to imitate the vertebrate spine of a snake in order to paint the interior of automobiles. 5 ____.

The challenge of equipping robots with the skills to operate independently, outside of a factory or laboratory, has made heavy demands on the ingenuity and creativity of academic, military, and industrial scientists for years. Simply put, robot hands — like robot legs, or eyes, or reasoning powers – have a long way to go before they can approach what biological evolution has achieved over the course of hundreds of millions of years. Much more will have to happen in laboratories around the world before robots can be compared to nature’s handwork.

a) Office Equipment.

b) Office Automation.

c) Computers and Periphery.

d) How the Modem Works.

The rapid growth of the service sector of the economy has furnished a new market for sophisticated office automation. Computers 1_______and specialized software programs are taking over tasks such as facsimile transmission or FAX, mail, and telecommunications that were once performed by separate pieces of equipment. In fact, the computer has virtually taken the place of typewriters, calculators, and manual accounting techniques and is rapidly taking over graphics design, production scheduling, and engineering design.

Desktop PCs have become increasingly affordable as a result of industry-wide adoption of the architecture of the PC introduced in 1981. Although it has become feasible to provide virtually every office worker with a PC, 2________. In the late 1980s and early 1990s, many companies began programs of linking or "networking" multiple PCs into a unified system.

The local area network (LAN) was created in response to the need for a standardized system of linking computers together in a company. The most common method used to connect computers to a network is by means of coaxial cables. Newer-generation networks use optical fiber connections. When computers are not in close physical proximity, networks may use microwave radio or infrared radiation to link the computers. Microwave radio requires a dish antenna for transmission and reception; infrared radiation requires a lens for transmission and a mirror and lens for reception.3________.

The need for computer "connectivity" has established the usefulness of the peripheral device known as the modem. Modems permit two computers to communicate by telephone in order to access databases, transmit files, upload and download facsimile transmissions, and send and receive electronic mail. Early transmission speeds using this equipment were relatively slow—300 baud. 4__________.

Text materials in typed or printed form can be input directly into a computer by means of a scanner. To read text, optical character recognition (OCR) software must first be used to convert printed documents electronically into computer-readable files. Scanners obviate the need to rekey printed text in order to input it; they can also be used to input graphic material.

Computer-based electronic message systems are an alternative to telephonic communications or conventional interoffice memoranda.

E-mail has become a key part of the communications networks of most modern offices. Data and messages can be transmitted from one computer to another using telephone lines, microwave links, communications satellites, or other telecommunications equipment.5_________. E-mail is sent through a company's own local area network or beyond, through a nationwide or worldwide communications network. E-mail services use a central computer to store messages and data and to route them to their intended destination. With a subscription to a public e-mail network, an individual PC user needs only a modem and a telephone to send and receive written or vocal messages.

Задание 4. Read the text. Then read the titles. Which of the following titles is the best?

d) Cellular Phone Network.

e) Personal Communications Services.

f) Cellular Radio Telephone

g) Types of Telephones.

Cellular radio telephone is also called cellular telephone or cell phone, it is a low-powered, lightweight radio transceiver (a combination transmitter-receiver) that provides voice telephone service to mobile users. Cellular telephones operate as portable telephones; whereas normal telephones require a cord that connects to a jack in order to access the extensive wire line networks operated by local telephone companies, cellular telephones are not restricted by a cord. 1________.

Cellular telephones work by transmitting radio waves to cellular towers. 2 ________. The area a tower can cover is referred to as a cell; the towers within these cells are networked to a central switching station, usually by wire, fiber-optic cable, or microwave. The central switching station handling cellular calls in a given area is directly connected to the rest of the wired telephone system. Cellular calls are picked up by the towers and relayed to the rest of the telephone network. Since the cells overlap, as a mobile caller moves from one cell into another, the towers "hand off" the call so communication is uninterrupted.

3________, and cellular coverage is increasing in rural areas. Due to the convenience and mobility of cellular telephones, users generally pay a higher fee than they would for normal telephone use. A newer generation of cellular radio technology, called Personal Communications Services (PCS), operates much like earlier cellular services, but at higher frequencies (around 1900 MHz). PCS also utilizes completely digital transmissions, rather than the analog transmissions that many current cellular telephones use. Digital transmissions convert sound into digital form, which can be transmitted faster and more efficiently than analog signals.

Both cellular radio and PCS use high-frequency radio waves to transmit calls. High-frequency waves have short wavelengths that pass by a given point at a very high rate. They provide better sound quality than lower-frequency waves (such as AM radio) and ensure reliable cellular links to and from towers over short distances. However, high-frequency signals cannot effectively travel as far as low-frequency signals. For cellular networks, this limited range is advantageous, because it means the same frequencies can be reused at nearby locations. This ability to reuse frequencies is helpful, because there are a limited number of radio frequencies available to cell phone companies. 4________.

The transceiver inside a cellular phone is a much more complex device than a conventional phone used over the wire line network. A cellular telephone has circuitry that creates a unique identity code that is used to locate and track the telephone and is necessary for coordinating calls to and from the telephone, and for billing such calls.

New cellular telephones have several features. These new phones have a small liquid crystal screen that can display the telephone number that is being called, the number of an incoming call, or a short text message, much like a pager displays this information. Other types of cellular telephones have a variety of functions that include a memory for frequently called numbers and a lock to deter theft. 5________.

Rechargeable batteries provide the usual source of power, but most cell phones can also be attached to the cigarette lighter in a vehicle or to some other external power device.

d. Radio-Navigation Systems.

Global Positioning System (GPS) is a space-based radio-navigation system, consisting of 24 satellites and ground support. GPS provides users with accurate information about their position and velocity, as well as the time, anywhere in the world and in all weather conditions.

GPS, formally known as the Navstar Global Positioning System, was initiated in 1973.1________. GPS satellites carry atomic clocks that provide extremely accurate time. The time information is placed in the codes broadcast by the satellite so that a receiver can continuously determine the time the signal was broadcast. The signal contains data that a receiver uses to compute the locations of the satellites and to make other adjustments needed for accurate positioning. The receiver uses the time difference between the time of signal reception and the broadcast time to compute the distance, or range, from the receiver to the satellite. The receiver must account for propagation delays, or decreases in the signal's speed caused by the ionosphere and the troposphere. With information about the ranges to three satellites and the location of the satellite when the signal was sent, the receiver can compute its own three-dimensional position.

An atomic clock synchronized to GPS is required in order to compute ranges from these three signals. However, by taking a measurement from a fourth satellite, the receiver avoids the need for an atomic clock. 2_______.GPS comprises three segments: the space, control, and user segments. The space segment includes the satellites and the Delta rockets. GPS satellites fly in circular orbits at an altitude of 20,100 km (12,500 mi) and with a period of 12 hours. The orbits are tilted to the earth's equator by 55 degrees to ensure coverage of polar regions.3________. Each satellite contains four atomic clocks.

The control segment includes the master control station in Colorado, and monitor stations in the Atlantic, Indian and South Pacific Oceans. These stations monitor the GPS satellites. The control segment uses measurements collected by the monitor stations to predict the behavior of each satellite's orbit and clock. The prediction data is uplinked, or transmitted, to the satellites for transmission to the users. 4________.

The user segment includes the equipment of the military personnel and civilians who receive GPS signals. With more than 500,000 GPS receivers, the civilian community has its own large and diverse user segment. Surveyors use GPS to save time over standard survey methods.5_______. GPS tracking systems are used to route and monitor delivery vans and emergency vehicles. In a method called precision farming, GPS is used to monitor and control the application of agricultural fertilizer and pesticides. GPS is available as an in-car navigation aid and is used by hikers and hunters. It is also used on the Space Shuttle. Because the GPS user does not need to communicate with the satellite, GPS can serve an unlimited number of users.

When users want to access the Web, they use the Web browser on their client computer to connect to a Web server. Client computers connect to the Web in one of two ways. Client computers with dedicated access to the Web connect directly to the Web through a router (a piece of computer hardware that determines the best way to connect client and server computers) or by being part of a larger network with a direct connection to the Web. Client computers with dial-up access to the Web connect to the Web through a modem,1________. Some modems send signals over cable television lines or special high-capacity telephone lines. The client computer and the Web server use a set of rules for passing information back and forth. The Web browser knows another set of rules with which it can open and display information that reaches the client computer.

Web servers hold Web documents and the media associated with them.2________. Client computers access information from Web servers, and any computer that a person uses to access the Web is a client, so a client could be any type of computer. The set of rules that clients and servers use to talk to each other is called a protocol. The Web, and all Internet formats, uses the protocol called TCP/IP (Transmission Control Protocol/Internet Protocol). However, each part of the Internet—such as the Web, gopher systems, and File Transfer Protocol (FTP) systems—uses a slightly different system to transfer files between clients and servers.

The address of a Web document helps the client computer find and connect to the server that holds the page. The address of a Web page is called a Uniform Resource Locator (URL). A URL is a compound code that tells the client’s browser three things: the rules the client should use to reach the site, the Internet address that uniquely designates the server, and the location within the server’s file system for a given item. An example of a URL is http://encarta.msn.com/. The first part of the URL, http://, shows that the site is on the World Wide Web. Most browsers are also capable of retrieving files with formats from other parts of the Internet, such as gopher and FTP. Other Internet formats use different codes in the first part of their URLs—for example, gopher uses gopher:// and FTP uses ftp://. The next part of the URL, encarta.msn.com, gives the name, or unique Internet address, of the server on which the Web site is stored. Some URLs specify certain directories or files, such as http://encarta.msn.com/explore/default.asp— explore is the name of the directory in which the file default.asp is found.

The Web holds information in many forms, including text, graphical images, and any type of digital media files: including video, audio, and virtual reality files. Some elements of Web pages are actually small software programs in their own right. These objects, called applets (3_______), follow a set of instructions written by the person that programmed the applet. Applets allow users to play games on the Web, search databases, perform virtual scientific experiments, and many other actions.

The codes that tell the browser on the client computer how to display a Web document correspond to a set of rules called Hypertext Markup Language (HTML). Each Web document is written as plain text, and the instructions that tell the client computer how to present the document are contained within the document itself, encoded using special symbols called HTML tags. The browser knows how to interpret the HTML tags, so the document appears on the user’s screen as the document designer intended. In addition to HTML, some types of objects on the Web use their own coding. Applets, for example, are mini-computer programs that are written in computer programming languages such as Visual Basic and Java.

Client-server communication, URLs, and HTML allow Web sites to incorporate hyperlinks, which users can use to navigate through the Web. Hyperlinks are often phrases in the text of the Web document that link to another Web document by providing the document’s URL when the user clicks their mouse on the phrase.4__________. Hyperlinks allow users to jump between diverse pages on the Web in no particular order. 5________, and scientists believe it bears a striking resemblance to the way the human brain accesses stored information. Hyperlinks make referencing information on the Web faster and easier than using most traditional printed documents.
