CheckPoint TCP/IP LAN Plan 1‚ 2‚ 4‚ 11‚ 14‚ 15‚ 16‚ & 20 1. An IPv6 address is made up of how many bits? d. 128 IPv6 uses 128-bit hexadecimal addresses and has built-in security and QoS features. An IPv6 address is 128 bits rather than the 32 bits in an IPv4 address. This length increases the number of possible addresses from about 4 billion in IPv4 to 3.4 x 1038 addresses (that’s 34 followed by 37 zeros!) in IPv6. Unless IP addresses are assigned to every star in the universe‚

ADDERS AND SUBTRACTORS September 18th‚ 2007 CSC343 Fall 2007 Prepared by: Steven Medina PURPOSE The purpose of this lab is to show you how to implement an adder using Quartus. As the name implies‚ adders are used to add two sets of values together. Adders are a very common design in digital design. For example‚ a CPU will use an adder to have its program counter point to its next instruction. This is done by adding a constant value of 4 to the current instructions memory address. You will
