INTRODUCTIONInformation technology refers to process of development, maintenance and usage ofcomputer systems, networks, software and hardware (Virtualization techniques in cloudcomputing. 2019). This comprises of usage of processing and distribution of data (raw facts,figures, etc.). IT infrastructure is defined as composite software, hardware, network services andresources which are required for management, operations and existence of enterprise within ITenvironment. In this assignment Westpac Banking Corporation is taken into consideration. It isan Australian bank which provides financial services. They are headquartered Westpac place,Sydney with around 1204 branches and render their services worldwide. This report deals withscope of network, their segments, network devices and IP addresses along with their subnetmask. Apart from this, two organisations are analysed which can be used to host email and webservers, virtualisation and cloud computing.Part I1. Examine geographical scope of network and network backbone devices with categorisation ofdifferent network segments, users and applications.Local area network : It's short form is LAN which is being considered as a networkwhich basically connects computers along with the devices which helps in transferring the datain a small geographical area like home, school, computer laboratory, office building, or closelypositioned group of buildings. Basically, this type of system could only be used by Westpacwithin a office. Along with this, it can be said that defining characteristics of LANs, in contrastto WANs (Wide Area Networks), and basically this consist with higher data transfer ratesconnected with leased telecommunication lines. Away with this, current Ethernet or other IEEE802.3 basically get LAN technologies operate at speeds up to 10 Gbit/s. 1
