Information technology is the management and processing of electronic data or information, especially within an organization as opposed to personal use, through hardware, software and peripheral systems, including telephony equipment. Software development, application management, hardware components such as desktop support, server or storage administration and network architecture are the streams of specialization within the IT field. IT Experts seek employment as a chief information officer (CIO), chief technology officer (CTO), IT manager, systems administrator, application manager, developer, and architect.

"IT can provide the edge a company needs to outsmart, outpace and out-deliver competitors," says Edward Kiledjian, a Chief Information Security Officer and technology blogger.

Today, no modern business can live without a reliable IT infrastructure. IT experts are increasingly involved in resolving the problems arising due to;

Data overload: Businesses need to manage and process big data, which requires sophisticated hardware and software, processing power and human and computer analytical skills.

Mobile and wireless usage: Work from home has become the norm of the day, which involves mobile devices, tablets and laptops with wireless hotspots and roaming ability.

Cloud services: Businesses are now inclined to utilize cloud services and third-party hosting platforms to store their massive data instead of building their server farms.

Bandwidth for video hosting: As the popularity of video conferencing increases, so is the need for more bandwidth.

5G: Total IT infrastructures, from mobile devices to routers and switches, are being upgraded to derive benefits from the emergence of 5G technology.

Internet of things (IoT): Due to the rise of IoT, the interconnection via the internet of computing devices embedded in everyday objects, enabling them to send and receive data, encryption and security protocols need to be upgraded and diligently implemented to avoid a security breakdown.
