What is IT career_What is IT work

IT career is the traditional IT industry jobs, mainly engaged in computer work

IT is known as information technology (INFORMATIONTECHNOLOGY), that is, information science and technology and industry, which covers a wide range of industries that deal with or apply to information technology, such as banking, consulting, hospitals, publishing, manufacturing, film and television, etc. They **** the same characteristics are dependent on information and information systems. They **** the same characteristics are dependent on information and information systems.

The widespread use of Internet technology is a sign of the information society. Different people and different books have different interpretations of this. But a basically agreed view is that IT has the following three components:

1, sensor technology which is the extension and expansion of the human sensory organs, the most obvious example is the bar code reader;

2, communication technology which is the extension and expansion of the human nervous system, to take on the transmission of information;

3, computer technology which is the extension of the human brain function and expansion, to take on the processing of information. and expansion, to assume the function of information processing.

Extended information

1, IT life cycle

The average life cycle of an IT product is about five years, but some applications reside on the same hardware for longer than that.

IT refresh means upgrading to a faster, more intuitive version of an existing platform. However, when different hardware provides better functionality, significantly improved performance, or greater reliability, consider upgrading hardware at the same time as the migration process.

2. IT value

The value that IT equipment creates for an organization lies in IT data storage and utilization, and should be weighed against its intrinsic value, not the price at which it is sold as used equipment. The optimal time to replace hardware is when the intrinsic value of the server decreases and the value of its work also decreases. Automated asset management tools can help users accurately assess depreciation rates.

The intrinsic value of IT equipment is maintained by the need for spares and parts in other organizations, but this is not the only market for used IT systems.

Reduce IT refresh and run your most important workloads on the latest IT hardware. As opposed to selling or purging old systems, IT can use this hardware to host non-critical work operations until they are literally old hat.
