What is IT & ICT? What types of jobs are there

in these fields?

#WorkToEquality

Information technology (IT) is the application of computers and telecommunications equipment to store, retrieve, transmit and manipulate data, often in the context of a business or other enterprise.

,

Information and communications technology (ICT) is often used as an extended synonym for information technology (IT), but is a more specific term that stresses the role of unified communications and the integration of telecommunications (telephone lines and wireless signals), computers as well as necessary enterprise software, middleware, storage, and audio-visual systems, which enable users to access, store, transmit, and manipulate information.

WIKIPEDIA SAYS IT and ICT are…

¿What?

Mobile'Device'

Let’s say you submit a bid on Marktplaats or write a comment on Facebook in the mobile app.

#WorkToEquality

Mobile'Device'

Your action goes to your mobile provider’s cellular towers.

The telecommunications systems translate and relay that information to “The Internet”.

The data from the mobile device gives the Internet instructions on what group of server computers to go to. ""The image on the right is a typical group of server computers in a data center. Facebook has tens of thousands of these across the world.

When the server computers process your action, they send back the changes to computer devices (e.g., the added comment in Facebook).

Let’s look at the IT / ICT technologies and professions which allow this.

#WorkToEquality

Hardware Engineering

The people who design and build the computer devices used, as well as any physical item used in IT/ICT, are

called HARDWARE ENGINEERS.

Their work has sped up machines significantly over the years. In fact, every 2.5 years, the speed of computers

double. This allows the internet products to do more.

#WorkToEquality

Hardware Engineering

The above are the guts of a device. It includes silicon chips and platinum connections.

#WorkToEquality

Telecommunications

Telecommunications is the field of engineering which deals with data moving between devices over mobile cell lines as well as the internet. It is a rapidly growing field.

Network EngineeringNetwork Engineering is the field of

engineering which handles all of the communications between devices.

Software Development & Maintenance

This is the field your presenters tonight specialise in. It will be covered in detail later in this

presentation.

#WorkToEquality

Site Operations /System Administration

Site Operations / System Operations Engineers manage all of the server machines, their configurations, setup, maintenance and our hardware. They focus on the data centres and networking.

#WorkToEquality

Helpdesk, IT Support, IT Technicians

These IT workers make sure that the machines in a company are working. They make sure that software is up-to-date, that we can connect to the networks, and that we are up-to-date on anti-virus software. It is an entry-point into the IT field.

#WorkToEquality

Customer Service and Tech Support help when customers have a problem. This is an entry point into IT. Ability to solve problems and speak with customers is critical.

Customer Support &Tech Support

#WorkToEquality

Summary so far •  Hardware Engineers are electronics specialists who design and build the

devices and their components

•  Telecom Engineers are specialised network engineers who specialise in the telecommunications field.

•  Network Engineers build, manage and maintain hardware which allows communication flow between devices.

•  Software Development and Maintenance will be covered shortly.

•  Site Operations / System Administration manages the server computers, their configurations, hardware and software.

•  IT Support, Helpdesk and IT Technicians are IT staff in companies who make sure that people’s devices (computers, laptops, mobiles, tablets and wearables) are working.

•  Customer Support and Tech Support are IT staff who answer questions for people who have problems with a product.

#WorkToEquality

So what does it take to develop and maintain internet software?

#WorkToEquality

We expect internet sites to work: be reliable, quick, secure, to be improving all of the time, read our minds, and more. How hard can it be?

#WorkToEquality

•  Programmers / Developers: ability to code, think abstractly, tell a story with the software and apps they are building, ability to focus on the user.

•  Testers / QA: Understanding of technology and its intricacies, ability to find things which are not “right” and explain to others, customer focus, ability to code

•  Data analysts / data scientists: ability to manipulate data and numbers to understand why people do certain actions. A mathematical mind and love of analysis is required.

•  User Experience Designer / UI Designer: creativity, visual acuity, understanding of how a user would interact with the software or app.

•  Product Managers and Product Owners: ability to translate fuzzy requests from many into concrete requirements which can be coded by developers and tested by testers. Innate understanding of the market, ability to talk to users and understand their needs, ability to talk to abstract thinkers, clarification, and leadership are critical for this job.

•  Project Managers: Understanding of the software development process, be pushy but not bossy towards the delivery of software, and ability to work with third parties and deadlines.
