4.      (Multimedia systems) are known for their educational and entertainment value, which we call edutainment.

5.      (Multimedia) combines text with sound, video, animation, and graphics, which greatly enhances the interaction between user and machine and can make information more interesting and appealing to people.

6.      (Expert systems) software enables computer to ‘think’ like experts.

7.      (Connectivity) enables computer and software that might otherwise be incompatible to communicate and to share resources.

8.      The (information superhighway) is designed to significantly expand this interactive connectivity so that people all over the world will have free access to all these resources.

9.      Most PCs are held back not by the speed of their (main processor), but by time it takes to move data in and out of memory.

10.  The idea is to use a small number of very fast memory chips as a buffer or (cache) between main memory and the processor.

11.  If it finds the data in the cache then this counts as a (“cache hit”) and the processor not go through the more laborious processor reading data from the main memory.

12.  The whole process is controlled by a group of logic circuits called the (cache controller).

13.  One of the cache controller’s main jobs is to look after (“cache coherency”) which means ensuring that any changes written to main memory are reflected within the cache and vice versa.

14.  The main alternative is the (“write-back” cache) which allows the processor to write change only to the cache and not to main memory.

15.  RAM: Holds data read and written to it by the processor

16.  Processor: Controls all the operations in a computer.

17.  Mouse: Controls the cursor.

26.  These contain (a radar set), a (microprocessor) and a camera equipped with a flash.

27.  If a car is moving towards the radar, the reflected (signal) will bounce back with a slightly smaller wavelength.

28.  If away from the radar, the waves will reflect with a slight longer (wavelength).

29.  The information is stored on a (smart card) for transfer to the police computer.

30.  Using (mailmerge) a standard letter is then printed off addressed to the vehicle owner.

31.  The objective of (information systems) is t provide information to all levels of management at the most relevant time, at an acceptable level of accuracy, and at an economical cost.

32.  A (tour operator) is concerned about purchasing power and its effect on holiday bookings and the political situation prevailing in the various countries.

33.  The detail contained in reports containing information varies according to the position of the recipient in the (hierarchical managing structure).

34.  (Functional management) require information relating to the departments they are responsible for in sufficient detail to enable them to apply whatever measures are required  to bring situations into line with appropriate action can be taken to control them.

35.  Above the (transaction-level systems) are  the decision support – systems.

36.  All mail can be opened in the mail room and scanned into the computer using optical character (recognition) (OCR).

37.  An (operating system) is a master control program which controls the functions of the computer system as a whole and the running of application programs.

38.  Some operating systems are adopted as (“industry standards”) and these are the ones which should be evaluated because they normally have a good software base.

39.  (Mainframe computer) usually process several application programs concurrently, switching from one to the other, for the purpose of increasing processing productivity.

40.  In (multi – user environments) an operating system is required to control terminal operations on a shared access basic as only one user can access the system at any moment of time.

41.  An operating system is stored on disk and has to be booted into the (internal memory) (RAM) where it must reside throughout processing so that commands are instantly available.

42.  Many (microcomputers) function under control of a disk operating  system  known DOS

43.   When a brand new computer comes off the factory assembly line, it can do nothing.

44.  The (hardware) need software to make it work.

45.  But an (application software package) does not communicate directly with the hardware.

46.  Between the applications software and the hardware is a (software interface) – an operating system.

47.  An (operating system) is a set of programs that lies between applications software and the computer hardware.

48.  The most important program in the operating system, the program that manages the operating system, is (the supervisor program) most of which remains in memory and is thus referred to as resident.

49.  An operating system has (three) main functions.

50.  All input and output operations, although invoked by an (applications program) are actually carried out by the operating system.

51.  Break – through in technology, such as (speech recognition), are enabling new ways of interfacing with computers.

53.  XML – based formats enable users to view content, including local and network files, within a single (browser interface).

54.  Speech will become a major component of user interfaces, and applications will be completely redesigned to incorporate (speech input).

55.  (A mouse) is a very efficient device for desktop navigation, for example, but not for changing the style of a paragraph.

56.  (Multimodal interfaces) will involve more than just traditional input devices and speech recognition.

57.  As these technologies enter (mainstream applications), they will have a marked impact on the way we work with personal computers.

58.  One of principal (motivations) for using OOP is to handle (multimedia applications) in which such diverse data types as a sound and video can be packaged together into (executable modules).

59.  Perhaps the key feature of OOP is (encapsulation) – bundling data and program instructions into modules called (“objects”).

60.  Each time a user selects an object, (instructions) inside the object are executed with whatever properties or data the object holds, to get to the next step.

61.  Many industry observers feel that the (encapsulation feature) of OOP is the natural tool for complex applications in which speech and moving images are integrated with text and (graphics).

62.  A second key feature of OOP is (inheritance).

63.  (Inheritance) is a useful property in rapidly processing business data.

64.  A third principle behind OOP is (polymorphism).

65.  The combination of encapsulation, inheritance and polymorphism leads to (code reusability).

66.  The name comes from MPEG (pronounced – EM – peg), which stands for the (Motion Picture Experts Group), MPEG develops standards for audio and video compression.

67.  The Windows Media Player will decode the file and route the signals to your soundcard and then to your (speakers).

68.  To control what music you play, player let you group songs into (playlists) and randomize the (selections).

69.  To control how the music sounds, they offer (spectrum analyzers, graphic equalizers, and frequency displays).

70.  A (track info) button gives you the information on the MP3 file’s tag.

71.  (A ripper) is a program that rips songs from a CD in your CD-ROM drive and turns them into WAV files.

72.  Many MP3 players incorporate rippers and (encoders) and can do both steps in one.

73.  (A bridge) is a hardware and software combination used to connect the same type of network.

74.  (Bridge) can also partition a large network into two smaller ones and connect two LANs that are nearby each other.

75.  (A router) is a special computer that directs communicating messages when several networks are connected together.

76.  High – speed routers can serve as part of the Internet (backbone).

77.  (A gateway) is an interface that enables dissimilar networks to communicate, such as two LANs based on different topologies or network operating systems.

78.  (A backbone) is the main transmission path, handling the major data ttraffic, connecting different LANs together.

79.  (A LAN) is a0 network contained within a small area, for example a company department.

80.  (A modem) is a device for converting digital signals to analogue signals and vice versa to enable a computer to transmit and receive data using an ordinary telephone line.

81.  In the (star configuration), the central computer performs all processing and control functions.

82.  The (star configuration) has two major limitations.

83.  The (star network) is very susceptible to failure, either in the central computer or the transmission links.

84.  The central (switch), which could be a telephone exchange, is used to connect different device on the network directly.

85.  A (bus network) consists of one piece of cable terminated at each end to which all devices are connected.

86.  In a bus – based network each device is able to broadcast a (message) when it has detected silence for a fixed period of time.

87.  (Computer networks) link computer by communication lines and software protocols, allowing data to be exchanged rapidly and reliably.

88.  Traditionally, networks have been split between (wide area networks (WANs) is a network connected over long – distance telephone lines) and a (LAN) is a localized network usually in one building close together.

89.  (Network) were used to provide terminal access to another computer and to transfer files between computer.

90.  Today, networks carry e – mail, provide access to public database and bulletin boards, and are beginning to be used for (distributed systems).

91.  Network also allow users in one locality to share expensive (resources), such as printers and disk – systems.

92.  (Distributed computer system) are built using networked computer that co-operate to perform tasks.

93.  The high-quality bitmapped graphics (screen) of a personal computer or workstation provides a good user interface.

94.  The (mainframe), on the other hand, can handle large numbers of queries and return the results to the users.

95.  The PC passes the (query) written in a special language e.g. (Structured Query Language) _ SQL, to the mainframe, which then parses the query, returning to the user only the data requested.

96.  During the early part of this decade, synchronous (orbit satellites) lowered the price of long-distance telephone call, enabling computer data and television signals to be distributed more cheaply around the  world.

97.  Since then, (fibre-optic cable) has been installed on a large scale, enabling vast amounts of data to be transmitted at a very high speed using light signals.

98.   The impact of (fibre optics) will be considerably to reduce the price of network access.

99.  Global communication and (computer network) will become more and more a part of professional and (personal lives) as the price of microcomputers and network access drops.

100.                      At the heart of the (Internet Protocol) (IP) portion of TCP/IP is a concept called the Internet address.

101.                      Although data – delivery system like Ethernet or X.25 bring their packets to any machine electrically attached to the cable, the (IP modules) must know each other’s Internet addresses if they are to communicate.

102.                      A machine acting as a (gateway) connecting different TCP/IP networks will have a different Internet address on each network.

103.                      Internal look-up tables and software based on another standard – called (Resolution Protocol) – are used to route the data through a gateway between networks.

104.                      The (Transmission Control Protocol) (TCP) part of TCP/IP comes into operation once the packet is delivered to the correct Internet address and  application port.

105.                      (Software packages) that follow the TCP standard run on each machine, establish a connection to each other, and manage the (communication exchanges).

106.                      A (data-delivery system) like Ethernet doesn’t promise to deliver a packet successfully.

107.                      After TCP bring the data packet into a computer, other (high-level program) handle it.

108.                      The wireless alternatives come in (two) forms: (satellite and cellular).

109.                      Downstream bandwidth is provide via a dedicated (satellite dish) connector hardware and proprierity software.
