Information technology contains three major components:
1. Hardware (such as computers).
2. Software (such as operating systems and office software)
3. Data (the facts, figures, and numbers collected from the daily activities of the organization).
Information systems contains those same components, with two additionsi
1. People (such as the employees who work there).
2. Procedures (such as the step-by-step instructions employees follow to complete a sale).
IT = Hardware + Software + Data.
Is = IT + People + Procedures.
As a business professional, why does this difference matter to you? Why does knowing the difference help you avoid some common
mistakes?

Write a new lc-3 trap subroutine (i. e. a subroutine that will be invoked via the trap instruction) that will receive a numeric digit entered at the keyboard (i. e. an ascii character), echo it to the screen, and return in r0 the corresponding numeric value: so if the user types the digit '7', the character '7' will appear on the screen, but the value returned in r0 will be b0000 0000 0000 0111 (#7) you may not use any trap calls in your code - you must implement the "polling" code that interrogates the keyboard status and data registers. ; getnum_tsr ; a subroutine for obtaining a numeric value ; given ascii numeric digit input to keyboard. ; the numeric digit is echoed to the console (e. g. '7' = b0000 0000 0011 0111), ; but the value returned in r0 is the actual numeric value ; corresponding to the digit (e. g. b0000 0000 0000 0111 =
