is on ‘how network architecture has changed over the decade’. In this report‚ I’d be talking about different network architecture that has been adopted over the past years. I would as well put light upon early network architecture and the advantages and disadvantages of former and why and how latter architecture were needed and adopted. Network architecture is the design of communication network. It is the complete framework of computer network. The diagram of the network architecture provides

Abstract: Wireless technologies have experienced an enormous growth in the last decades. The wireless personal area networks (WPANs) and wireless local area networks (WPANs) are heterogeneous networks which are used in different applications. Two networks‚ called Wifi (IEEE 802.11 WLAN) and ZigBee (IEEE 802.15.4 WPAN)‚ which operates in 2.4 GHz frequency. Spectrum sharing is an effective technique which is used to enhance spectrum utilization. However the coexistence and Interoperability is a critical

Systems Network Architecture (SNA) is IBM’s proprietary networking architecture created in 1974.[1] It is a complete protocol stack for interconnecting computers and their resources. SNA describes the protocol and is‚ in itself‚ not actually a program. The implementation of SNA takes the form of various communications packages‚ most notably Virtual telecommunications access method (VTAM) which is the mainframe package for SNA communications. SNA is still used extensively in banks and other financial
