Define a method named roleOf that takes the name of an actor as an argument and returns that actor's role. If the actor is not in the movie return "Not in this movie.". Ex: roleOf("Tom Hanks") returns "Forrest Gump". Hint: A method may access the object's properties using the keyword this. Ex: this. cast accesses the object's cast property.

roleOf: function(actorName) {

   if(!(actorName in this.cast)) {

       return "Not in this movie.";

   }

   return this.cast[actorName];

}

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
