A network protocol contains a four-byte integer, specifying the length of the payload in the packet. The implementation of this protocol has a mistake in it. When a packet is received, the protocol implementation needs to copy the payload to a buffer. It first copies the length field from the packet header to a variable, but the program forgets to convert the number into the host order. Assume the value of this variable is X. The program then allocates X bytes of memory to hold a copy of the payload. On a Little-Endian machine, if the payload of a received packet is 255 bytes, how much memory will be allocated?

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.

The process in which the system pressure remain constant is called a)-isobaric b)-isochoric c)-isolated d)-isothermal
