Q & A

What is IT infrastructure and what components does it include?

IT infrastructure is a combination of computer hardware, software, and services provided to maintain and manage technology systems. It includes computing platforms such as desktops, mainframes, handheld computers, cloud computing services, telecommunication technologies, and data management software.

What role do telecommunication technologies play in IT infrastructure?

Telecommunication technologies are used to transfer data, voice, and video between users of the IT system, enabling connectivity among customers, employees, and suppliers.

How does IT infrastructure support organizational applications?

IT infrastructure supports various applications that enhance organizational capabilities in areas like resource management, knowledge management, and other management spheres.

What are the four service perspectives of an IT team?

The four perspectives are: 1) development of infrastructure, coordinating construction and expenditures, 2) creation of IT standards, deciding technology models and usage, 3) training employees and managers on hardware, software, and IT investment management, and 4) research and development of potential future IT projects.

Why is research and development important in IT infrastructure?

Research and development is crucial because technological advantages can significantly impact competitiveness, making innovation an important part of any technology-driven company.

What are the five stages of IT infrastructure evolution?

The five stages are: 1) mainframe era with centralized computing, 2) personal computer era with decentralized computing and graphical interfaces, 3) client-server era connecting computers through networks, 4) enterprise computing era integrating networks using internet protocols, and 5) cloud and mobile computing era, enabling shared resources and flexible mobile work.

How did the mainframe era operate and what were its limitations?

In the mainframe era, many online terminals connected to a powerful mainframe computer using proprietary communication protocols. Computers were centralized and operated by professionals, which limited accessibility and customization.

What are the characteristics of the client-server era?

The client-server era connects multiple computers, where a server computer handles more complex tasks. Multi-tiered client-server architectures divide large computing tasks among less expensive computers, providing efficiency without centralized systems.

How did enterprise computing improve connectivity?

Enterprise computing connected different internal networks into one large network using internet protocols like TCP/IP, enabling information sharing within the organization and with the outside world through the internet.

What factors have driven the evolution of IT infrastructure?

Key drivers include declining communication costs, the introduction of the internet, new technology standards, laws of processing power, mass storage, and network growth, such as Moore’s Law, the Law of Mass Storage, and Metcalfe's Law.

How does mobile computing enhance the modern IT environment?

Mobile computing allows users to carry computing power with them, making work more flexible and enabling access to shared cloud resources for complex computing tasks on the go.
