Consider a packet of length 2000 bits which begins at end system A and travels over five links to a destination end system. These five links are connected by four packet switches. The propagation speed on all five links is 3*108 m/s. The transmission rate of all five links is 2 Mbps. For each packet switch, the processing delay is 1 msec. The length of the first link is 8,000 km, the length of the second link is 4,000 km, the length of the third link is 2,000 km and the length of the fourth and fifth link is 1000 km. Assuming no queuing delay, what is the end-to-end delay

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 =
