Information technology main areas in brief

In simple terms, information technology key areas of specialization can be represented by the following blocks for clarity:

Block 1

Operating systems – these are interfaces between the hardware, the applications and the actual user at the point where information is being generated or processed with respect to data input

Block 2

The networks – these provide the infrastructure plus the respective end point hardware upon which the information is transported from source to destination. It also has elements of data integrity and security of information which are vital. They include wired and wireless network technologies.

Block 3

Data bases and applications - these are programs that manage the archival, storage, retrieval and manipulation of information as desired by system users.

To break it down

Block 1 requires knowledge of operating systems, and on a higher level it requires knowledge and proficiency in Network operating systems. We are talking about Systems administrators who require certifications after gaining proficiency in operating systems including windows, Linux , UNIX and other Operating systems and their respective network operating versions. Microsoft certifications for the Certified Engineers and Certified Systems Administrators are some of the certifications for Microsoft you may consider attaining.

Block 2 requires comfortable knowledge in interconnection of devices, and the actual installations and configuration of these devices that are used in the network infrastructure. You will need Networking knowledge from the operating systems of the end devices e.g. workstations, servers, routers, firewalls and various switch types. We are talking about Network Engineers who may require certifications offered by the worldwide established Cisco Academies

Block 3 requires knowledge in database application and development, for example we can consider Oracle or Microsoft SQL certifications

We must also mention software developers and programmers who actually create and modify operating systems and application software.

i will be a little bit more specific about the certifications per key area in the next episode...
