What's the diffreence between a exe file and a data file?
Also, what is the difference between a OS Software and Application software?
example? and the last one How does a computer translates binary digits into output. Name the code and give an example of this code. HELPPPPPPPPPPPPPPPPPPPPPPP |

data file = any file created within an application
exe file = an executable file, or an application os (operating system) software = the software that controls the overall software of a computer application software = software within an os (operating system) computer translates binary digits into output by code and binary files are information and commands stored and used by hardware and software in their most elemental form I think binary is transfered to ascii form. Here's an example: Net{ 1. NUL::=character_nbr(0)::= Fills in time* (ASCII'NUL). 2. SOH::=character_nbr(1)::= Start Of Header (routing info)(ASCII'SOH). 3. STX::=character_nbr(2)::= Start Of Text (end of header)(ASCII'STX). 4. ETX::=character_nbr(3)::= End Of Text(ASCII'ETX). 5. EOT::=character_nbr(4)::= End Of Transmission(ASCII'EOT). 6. ENQ::=character_nbr(5)::= ENQuiry, asking who is there(ASCII'ENQ). 7. ACK::=character_nbr(6)::= Receiver ACKnowledges positively(ASCII'ACK). 8. BEL::=character_nbr(7)::= Rings BELl or beeps(ASCII'BEL)\a. 9. BS::=character_nbr(8)::= Move print head Back one Space(ASCII'BS)\b. 10. HT::=character_nbr(9)::= Move to next Tab-stop(ASCII'HT)\t. 11. LF::=character_nbr(10)::= Line Feed (ASCII'LF)\n. 12. VT::=character_nbr(11)::= Vertical Tabulation(ASCII'VT)\v. 13. FF::=character_nbr(12)::= Form Feed - new page or form(ASCII'FF)\f. 14. CR::=character_nbr(13)::= Carriage Return to left margin(ASCII'CR)\r. 15. SO::=character_nbr(14)::= Shift Out of ASCII(ASCII'SO). 16. SI::=character_nbr(15)::= Shift into ASCII(ASCII'SI). 17. DLE::=character_nbr(16)::= Data Link Escape(ASCII'DLE). 18. DC1::=character_nbr(17)::= Device control(ASCII'DC1). 19. DC2::=character_nbr(18)::= Device control(ASCII'DC2). 20. DC3::=character_nbr(19)::= Device control(ASCII'DC3). 21. DC4::=character_nbr(20)::= Device control(ASCII'DC4). 22. NAK::=character_nbr(21)::= Negative Acknowledgment(ASCII'NAK). 23. SYN::=character_nbr(22)::= Sent in place of data to keep systems synchronized(ASCII'SYN). 24. ETB::=character_nbr(23)::= End of transmission block(ASCII'ETB). 25. CAN::=character_nbr(24)::= Cancel previous data(ASCII'CAN). 26. EM::=character_nbr(25)::= End of Medium(ASCII'EM). 27. SUB::=character_nbr(26)::= Substitute(ASCII'SUB). 28. ESC::=character_nbr(27)::= Escape to extended character set(ASCII'ESC). 29. FS::=character_nbr(28)::= File separator(ASCII'FS). 30. GS::=character_nbr(29)::= Group separator(ASCII'GS). 31. RS::=character_nbr(30)::= Record separator(ASCII'RS). 32. US::=character_nbr(31)::= Unit separator(ASCII'US). 33. SP::=character_nbr(32)::= Blank Space character(ASCII'SP). 34. DEL::=character_nbr(127)::=Punch out all bits on paper tape(delete). }=::CTRL_CHARS. have a nice day? Last edited by neoh; Sep 23, 05 at 09:09 PM. |

0s & 1s are binary
1| .._ ...._ ..|_|..|_| 0 in an electrical current when the computer 'sees' a spike of voltage it registers a '1' when it sees a period without voltage (of the same length) it sees a 0. Each piece of binary is called a "bit". Each letter or number on a computer is made up of 8 bits in sequence. These are called bytes. 8 bits = 1 byte The code that computers use to translate each byte into a letter is called ASCII code. There are other code sets used (for different language sets (like german, russian, etc), but ASCII is the most common here's a couple sites with more detail: http://www.privateline.com/bitsandby...tsandbytes.htm http://www.kidsdomain.com/brain/comp...comp_les3.html http://www.discinterchange.com/TechT...r_basics_.html PS.
