Information technology (IT) is an area of business that emphasizes on the areas like computer technology support, computer network and database management, business software operations and information security.
In this current global scenario, information technology is facing new challenges and issues related to diverse aspects like the growth of internet, additional computational capabilities, latest operating systems, web security, wireless and mobile communication protocol systems, etc.
Information technology (IT) deals with diverse fields, and each field has its own key focus areas and roles to achieve certain tasks. A few of such areas are discussed below:
Proper selection of computer hardware is very important. This involves the identification of hardware components and their relationship with the computer usage, and also the management of different types of memory and storages like volatile, non volatile, etc. Computer hardware represents the information stored in a computer and also includes identification, selection, connection and configuring of various input and output peripherals to the PC.
Programming is entirely related to software aspects that are involved in developing the system software as well as the application software. Software implementation uses different languages and structures to write the code. Operating systems for several devices are also included in this field. This field deals with the software solutions for personal and professional use.
