Living in the IT Era
Topic: Lesson 1: Introduction to Information and Communications Technology (ICT)
Section 1: What is ICT?
ICT is a technology required for information processing, in particular, the use electronics
computers, communication devices and application software to convert, store, protect, process,
transmit and retrieve information from anywhere, anytime.
Information refers to the knowledge obtained from reading, investigation, study or
research. The tools to transmit information are the telephone, television and radio.
We need information to make decisions and to predict the future. For example, scientists
can detect the formation of a tsunami using the latest technology and warn the public to avoid
disasters in the affected areas. Information is knowledge and helps us to fulfill our daily tasks. For
example, forecasting the stock exchange market.
Communication is an act of transmitting messages. It is a process whereby information
is exchanged between individuals using symbols, signs or verbal interactions. Previously, people
communicated through sign or symbols, performing drama and poetry. With the advent of
technology, these „older‟ forms of communication are less utilized as compared to the use of the
internet, e mail or video conferencing.
Technology is the use of scientific knowledge, experience and resources to create
processes and product that fulfill human needs. Aiding Communication telephone and fax
machines are the devices used in extending communication, broadcasting information such as
news or weather reports effectively such as radio, television, satellites and the World Wide Web
(www) are powerful tools that can be use.
Section 2: Usage of ICT in our daily lives
Education
Teachers use computers to research for teaching materials, participate in online forum
and online conference.
Students use computers as reference tools for looking information in the internet.
Researchers use computers to collect and process data.
School administrators use computers for administrative purposes to ensure that entire
operations run smoothly.
Banking
Bank administrators can control the entire banking system and banking activities.
Customers to provide electronic banking services.
Businessman can save their time by using online services offered by banks.

Industry
To help workers operate machine.
To help researchers analyze and collect research data for future references.
To help administrators to oversee and control entire operations in the factory.
To facilitate production planning and control system.
E-commerce
To make buying and selling activities faster and more efficient through Internet
To connect online customers with suppliers to purchase products. This method can save
time and cost.
To help employees to communicate with their customers for any inquires and to get the
latest updates inventory to be informed to the customers.
Section 3: What is Information Technology (IT)?
Information Technology is the application of technology to solve business or
organizational problems on a broad scale. No matter the role, a member of an IT department
works with others to solve technology problems, both big and small.
Three primary pillars of responsibility for an IT department
1. IT governance refers to the combination of policies and processes that ensure
IT systems are effectively run and in alignment with the organization‟s needs.
2. IT operations refer to the catchall category for the daily work of an IT
department. This includes providing tech support, network maintenance, and security
testing and device management duties.
3. Hardware and infrastructure refers to all the physical components of IT
infrastructure. This pillar of IT includes the setup and maintenance of equipment like
routers, servers, phone systems and individual devices like laptops.
Section 4: Why is information technology important?
More and more companies want to implement more intuitive and sophisticated solutions.
“IT can provide the edge a company needs to outsmart, outpace and out-deliver competitors”.
Let‟s take a look at the needs that current and future IT specialists will be working on:
Data overload - businesses need to process huge amounts of data. This requires large
amounts of processing power, sophisticated software and human analytical skills.
Mobile and wireless usages - more employers are offering remote work options that require
smart phones, tablets and laptops with wireless hotspots and roaming ability.

Cloud services - most businesses no longer operate their own “server farms” to store
massive amounts of data. Many businesses now work with cloud servicesthird-party
hosting platforms that maintain that data.
Bandwidth for video hosting - videoconferencing solutions have become more and more
popular, so more network bandwidth is needed to support them sufficiently.
Section 5: IT software and hardware
IT includes several layers of physical equipment (hardware), virtualization and
management or automation tools, operating systems and applications (software) used to perform
essential functions. User devices, peripherals and software, such as laptops, smart phones or even
recording equipment, can be included in the IT domain.
Hardware is the umbrella term used to describe the physical collection of elements that
complete a whole computer system. Hardware encompasses the external tools that allow
users to operate a computer, such as the keyboard and mouse, outer elements of the machine
such as the monitor and tower, and internal components like the motherboard, graphics card,
and data storage.
Software - is the term used to define the sets of code, data, and instructions stored on the
computer‟s hard drive that operate the machine from behind the scenes. In other words
software allows a computer to actually perform tasks, without software; computer hardware
would be entirely useless. Application software gives functionality to an app, which will then
run on operating software within a computer.
Section 6: Common IT Careers
Chief information officer - This person is responsible for IT and computer systems that
support the enterprise's goals.
Chief technology officer - This person sets all technology goals and policies within an
organization.
IT director - This person is responsible for the function of all of the business's technology
tools and processes. This role is commonly called IT manager or IT leader.
Systems administrator - This person configures manages supports and troubleshoots a
multi-user computing environment. Within an enterprise, this role can be segmented by
technology, requiring an administrator or team dedicated to server, desktop, network,
virtualization or other components.
Application manager - This person's role centers on the provisioning and management of a
high-value business application, such as Exchange.
Developer - This person or team writes updates and tests code for programs to meet business
objectives internally or facing customers.
Architect - This person examines and changes IT functions to best support the business.
