BT22103 1936 - Turing machine, Alan Turing – decrypting Enigma, as central concept of modern computer. 1946 – The ENIAC, John W. Mauchly and J. Presper Eckert – The first digital computer. IT Infrastructure Components IT infrastructure – Platform for supporting all information systems in the business. Infrastructure Components Useful link, strongly recommend to watch all of that videos:- o https://youtu.be/xnyFYiK2rSY o https://youtu.be/vG_qmtdBPTU o https://youtu.be/rRSD128KWIM Contemporary Hardware Trend o The mobile digital platform Tablet computers Netbooks o Consumerization of IT and BYOD BYOD – bring your own device concept. o Nanotechnology and quantum computing Nanotechnology – to create computer chips and other devices that smaller than current technology. Quantum computing - use quantum physic to represent data. Contemporary Hardware Trend o Virtualization Process of presenting a set of computing resources such as data storage. Software-defined storage (SDS). o Cloud computing Computer processing, storage, software, and other services are provided as a shared pool of virtualized resources over a network, primarily the Internet. o Green computing Practices, design and manufacture the computer related that only produce minimise impact to the environment. High-performance and power saving processors. Types of Computers o Personal computers and mobile devices o Workstations o Servers o Mainframes o Supercomputers o Grid computing  Types of Computers Personal computers and mobile devices Workstations Types of Computers Servers Mainframes Types of Computers Supercomputers Grid computing Types of Computers Client-server computing o Form of distributed computing o Splits processing between “clients” & “servers” 1) Two-tiered client/server 2) Multi-tiered client/server architecture (N-tier) Web servers, Application servers Types of Computers – Data Storage, Input and Output o Magnetic disk o Solid State Drives (SSDs) o Optical disks o Magnetic tape o Storage networking: S A Ns o Input devices – E.g keyboard, mouse o Output devices – E.g monitor Data Storage, Input and Output Data Storage, Input and Output Magnetic disk SSDs Data Storage, Input and Output Optical disks Magnetic tape Data Storage, Input and Output Storage networking: S A Ns Issue of IT hardware 2023 Shortage of global chip Could last until 2023 Chip are almost in everything such as alarm clock, play station Impact of pandemic Shortage in many side of PC component Increase price Impact of pandemic
