Information Technology

Information technology (IT) is the use of computer systems or devices to access information. Information technology is responsible for such a large portion of our workforce, business operations and personal access to information that it comprises much of our daily activities.

Hardware

• Hardware refers to the external and internal devices and equipment that enable you to perform major functions such as input, output, storage, communication, processing, and more. There are two types of computer hardware: external and internal.


• In computer, hardware refers to all the physical parts of a computer, such as: The central processing unit (CPU), motherboard, monitor, mouse, keyboard, speakers, sound card, graphics card, computer data storage, etc.



Software

• Software comprises the entire set of programs, procedures, and routines associated with the operation of a computer system. The term was coined to differentiate these instructions from hardware—i.e., the physical components of a computer system.


• Computer software technology refers to the collection of programs, data, and instructions that enable a computer system to perform specific tasks. This includes everything from operating systems and application software to programming languages and development tools.



Networking

• Networking consideration Using platform technology to connect devices in the cloud is an emerging way of managing networks. In a cloud-based deployment, a user can access a single cloud instance of the network where all of the devices are supported, powered by the Internet.



Data Management

• Data management is the practice of collecting, organising, managing, and accessing data to support productivity, efficiency, and decision-making.Data can be described as unprocessed facts and figures. Plain collected data as raw facts cannot help in decision-making. However, data is the raw material that is organized, structured, and interpreted to create useful information systems.



Cybersecurity

• Cybersecurity is the protection to defend internet-connected devices and services from malicious attacks by hackers, spammers, and cybercriminals. The practice is used by companies to protect against phishing schemes, ransomware attacks, identity theft, data breaches, and financial losses.



Cloud Computing

• Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.



Internet of Things (IoT)

• The term IoT, or Internet of Things, refers to the collective network of connected devices and the technology that facilitates communication between devices and the cloud, as well as between the devices themselves.



Big Data

• Big data refers to extremely large and diverse collections of structured, unstructured, and semi-structured data that continues to grow exponentially over time. These datasets are so huge and complex in volume, velocity, and variety, that traditional data management systems cannot store, process, and analyze them.
