Does socket.recv work but not receive or read?

Question

Hello, I was messing around with sockets in Ruby, and stumbled upon some sample code that I was trying to modify and break. I want to know why it broke.

Server:

require "socket"  
dts = TCPServer.new('127.0.0.1', 20000)  
loop do  
  Thread.start(dts.accept) do |s|  
  print(s, " is accepted\n")  
  s.write(Time.now)  
  print(s, " is gone\n")  
  s.close  
  end  
end  

Client who works:

require 'socket'  
streamSock = TCPSocket.new( "127.0.0.1", 20000 )  
streamSock.print( "Hello\n" )  
str = streamSock.recv( 100 )  
print str  
streamSock.close 

Customer who is broken

require 'socket'  
streamSock = TCPSocket.new( "127.0.0.1", 20000 )  
streamSock.print( "Hello\n" )  
str=streamSock.read #this line modified
print str  
streamSock.close 

I know that I do streamSock.printn’t need it (as well as a naming scheme that is not a ruby), but I don’t understand why it readdoesn’t work, but recvit does, why is it?
