As most readers know, a stack is a first-in, last-out list. To visualize a stack, imagine a stack of plates on a table. The first plate put down is the last one to be picked up. The stack is one of the most important data structures in computing. It is frequently used in system software, compilers, and AI-based backtracking routines, to name just a few examples. The collection class that supports a stack is called Stack. It implements the ICollection, IEnumerable, and ICloneable interfaces. Stack is a dynamic collection that grows as needed to accommodate the elements it must store. Each time the capacity must be increased, the capacity is doubled. Stack defines the following constructors: public Stack( ) public Stack(int capacity) public Stack(ICollection c) The first form creates an empty stack. The second form creates an empty stack with the initial capacity specified by capacity. The third form creates a stack that contains the elements of the collection specified by c and an initial capacity equal to the number of elements. In addition to the methods defined by the interfaces that it implements, Stack defines the methods shown in Table 24-7. In general, here is how you use Stack. To put an object on the top of the stack, call Push( ). To remove and return the top element, call Pop( ). You can use Peek( ) to return, but not remove, the top object. An InvalidOperationException is thrown if you call Pop( ) or Peek( ) when the invoking stack is empty.

Smart tunnels are new in version 8.0. A smart tunnel is a secure connection using an SSL VPN session via clientless mode between a Winsock 2 TCP-based application and a server behind the ASA. In that sense, it s something like port forwarding or plug-ins.

A lumped directional coupler (Fig. 8.56) can be designed as follows: 1. R 50 ohms. Replacing R with a 50-ohm amplifier, or placing a highimpedance circuit in shunt with R, will permit reverse power to be sensed. 50 2. L . 2 f 3. C1 4. C2 1 . 2 f50 10(CF/20) . 2 f50
