Answer: BS

Question: What do computers attached to the ARPANET use for line endings?
Answer: CR-LF

Question: How were the connections supported? 
Answer: by transmitting a standard text format over the network

Question: Who else adopted this practice from Telnet?
Answer: The File Transfer Protocol

Question: Why did Telnet define an ASCII as a Network Virtual Terminal?
Answer: so that connections between hosts with different line-ending conventions and character sets could be supported

Question: What does ASCII code represent?
Answer: text in computers, communications equipment, and other devices that use text

Question: What does ASCII stand for?
Answer: American Standard Code for Information Interchange

Question: What happened after they decided agasint shifting?
Answer: ASCII required at least a seven-bit code

Question: Why did the committee debate adding a shift function?
Answer: would allow more than 64 codes to be represented by a six-bit code

Question: What is different in a shifted code?
Answer: some character codes determine choices between options for the following character codes

Question: Why did they decide against shifting code?
Answer: less reliable for data transmission as an error in transmitting the shift code typically makes a long part of the transmission unreadable

Question: What was the "escape" character originally intended for?
Answer: to allow sending other control characters as literals instead of invoking their meaning

Question: What does modern ESC code do?
Answer: most often used as an out-of-band character used to terminate an operation

Question: What does ESC generally mean for graphical user interfaces and windowing systems?
Answer: an application to abort its current operation or to exit (terminate) altogether

Answer: Control-C

Question: What was ASCII developed from? 
Answer: telegraphic codes

Question: What was the first commercial use of ASCII?

Answer: 1963

Question: When was the first major revision of the code done?
Answer: 1967

Question: Why did the committee consider a 8 bit code?
Answer: eight bits (octets) would allow two four-bit patterns to efficiently encode two digits with binary-coded decimal

Question: Why did the committee decide on 7bit instead?
Answer: minimize costs associated with data transmission
