CHAPTER TWO NETWORKING SYSTEMS AND LOCAL AREA NETWORKS (LAN) A network is a system of two or more computers that are connected in some manner. Each computer on the network has access to the files and peripheral equipment (such as printers or modems) on all the other computers on the network. The origin of local area networks can be traced‚ in part‚ to IBM terminal equipment introduced in 1974. At that time‚ IBM introduced a series of terminal devices designed for use in transaction-processing

BUTTERFLY NETWORK Butterfly network is a network with 2q nodes and q + 1 columns as an unfolded q-cube in order to facilitate the discussion‚ visualization‚ and analysis of hypercube routing algorithms. However‚ a butterfly network can be viewed as a parallel processing architecture in its own right. A butterfly architecture (Fig. A‚ left) has p = 2 q(q + 1) processors of maximum degree d = 4‚ a diameter of 2q = ∪(log p)‚ and a bisection width of ( – 1)2 q+1 + 0(2 q) = ∪(p/log p). A wrapped
