LANGUAGE SKILLS DEVELOPMENT
Exercise 1. Translate the sentences paying attention to Complex Object construction.
1. The transmission mode enables the receiving computer to know where one byte ends and next byte begins on the transmission medium. 2. A remote terminal enables the user to operate the distant computer, just as is that person were sitting in front of the distant computer and using its keyboard. 3. A good communication program directs the modem to dial the telephone number needed. 4. Electronic mail (e-mail) enables you to send messages from your computer for access at someone else’s computer. 5. Compared to the postal service, electronic mail has many advantages. Many systems let you check to see whether the recipient has accessed your message. 6. International electronic mail systems enable you to find “pen pals” all over the world. 7. Some e-mail systems require you to be part of the same system to receive your message. 8. Facsimile transmission enables you to send an image of a document over the telephone lines to anyone who has a fax machine. 9. Electronic mail, or e-mail, allows messages sent from your computer to be accessed by the recipient at his or her computer, as long as you both have access to the same e-mail system.10. Bulletin board systems (BBSs) enable independent computer users, using telecommunications, to interact with each other through a central contact. 11. Computer networks enable us to conquer another dimension – space. 12. The file allocation table enables the computer to locate data easily. 13. CD-erasable enables users to store, access, and reuse discs in the same way that floppy discs can be used. 14. Computer keyboards include keys that are designed to perform specific tasks. These keys enable the user to perform complex tasks easily when using the application. 15. Optical recognition systems enable the computer “to read” data by scanning printed text for recognizable patterns. 16. A debugger is system software that helps programmers identify errors. 17. Programming languages require certain formalities, and advanced text editors help programmers stick to the proper forms. 18. The event is a message that causes a procedure (subprogram) attached to the object to respond. 19. Fortran enables programmers to describe and solve mathematical calculations readily. 20. System software programs help the hardware components work together and provide support for application programs. 21. Engineers consider computing equipment to make production processes more effective.
