1. D. The OSI Reference Model has seven layers. A, B, C, and E are functions of the OSI Reference Model and therefore are incorrect answers.

Count is the most often used property because it contains the number of elements currently held in a collection. If Count is zero, then the collection is empty. ICollection defines the following method: void CopyTo(Array target, int startIdx) CopyTo( ) copies the contents of a collection to the array specified by target, beginning at the index specified by startIdx. Thus, CopyTo( ) provides a pathway from a collection to a standard C# array.

// Structures are good when grouping small amounts of data. using System; // Define a packet structure. struct PacketHeader { public uint PackNum; // packet number public ushort PackLen; // length of packet } // Use PacketHeader to create an e-commerce transaction record. class Transaction { static uint transacNum = 0; PacketHeader ph; // incorporate PacketHeader into Transaction string accountNum; double amount;

A function terminates execution and returns to the caller in one of two ways. The first is when the last statement in the function has executed and, conceptually, the function s ending curly brace (}) is encountered. (Of course, the curly brace isn t actually present in the object code, but you can think of it in this way.) For example, this function takes an address to a string as a parameter and displays the string backward:

compression forces at the junction between the ange and web. If the ange is partly immersed in deck slab concrete, the magnitude of compression in the slab will be different. 6. The transfer of planar shear in the slab is accompanied by vertical shear and bending in the slab.

// Require IComparable<T> interface. This method assumes // a sorted array. It returns true if what is inside the range // of elements passed to obs. public static bool InRange<T>(T what, T[] obs) where T : IComparable<T> { if(what.CompareTo(obs[0]) < 0 || what.CompareTo(obs[obs.Length-1]) > 0) return false; return true; }

A population of bacteria tends to double every four hours. If there are 5000 bacteria at 9:00 a.m., then how many will there be at noon
