Week 1-2 PRELIMS Flashcards
This term was first used in the early 1980s to indicate the
convergence of computer technology and communication technology.
Information Technology (IT)
In the 1990s, this term was more
widely used to replace IT – which is to give a greater emphasis on communication
aspect.
Information and Communication Technology (ICT)
What are the 3 types of Technology
Communication Technology
Content Technology
Computer Technology
It is also known as raw facts, and is considered as the backbone of everything we
do.
Data
Refers to all equipment and programs that are used to process and communicate
information.
Communication Technology
Refers to a variety of devices and touchpoints that delivers and markets relevant,
meaningful, and timely information.
Content Technology
This comprises of the available technology that are used in solving complex problems.
Computer Technology
It’s data that has been interpreted so that it has meaning for the user.
Information
What are the Impacts of ICT
Globalization
Knowledge Economy
Business Transformation
Digital Transformation
The process by which businesses or other organizations develop international influence
or start operating on an international scale
Globalization
An economy in which growth is dependent on the quantity, quality, and accessibility of
the information available, rather than on the means of production
Knowledge Economy
ICT has made a great impact in transforming businesses by the use of collaborative
work and teamwork through technological innovation.
Business Transformation
It means “Going paperless”
Digital Transformation
It serves as a broad blue print for acquiring, developing,
implementing and integrating ICT in order to support the business functions and
strategies of an organization.
ICT Architecture
What are the Elements of ICT Infastracture
ICT Resources

ICT Management
This supports and manages all ICT resources and ICT services in the organization.
ICT Infastracture
the physical equipment used for input, processing,
storing and output activities
Computer Hardware
the intangible parts of a computer system
Computer Software
consists of both physical devices and
software that links various computers located at various locations
Communication Technology
What are the 4 ICT Resources
Computer Hardware
Computer Software
Communication Technology
Data
This provide means for utilizing all ICT resources available within the organization.
ICT Services
This explains how the available ICT resources and ICT services are arranged, operated,
maintained and managed.
ICT Management
This starts by getting a holistic perspective on what the organization aims to achieve and
how it will do so.
ICT Strategic Planning
This is the process of obtaining ICT infrastructure.
ICT Acquisition
It is a clear set of ICT projects that will be carried out by the organization to support ICT
Strategic Plan.
ICT Operational Plan
What are the 4 Major Computer System Components
CPU
Primary Storage or Main Memory
Secondary Storage
Input and Output Peripherals
The part of a computer hardware that does the actual computation.
CPU or Central Processing Unit
It’s also known as the Brain of the Computer
CPU or Central Processing Unit
What are the components of CPU
CU or Control Unit
ALU or Arithemtic Logic Unit
Registers
This is the component of CPU which is responsible for controlling
the process of computation.
CU or Control Unit
This is the component of CPU which is responsible for
performing arithmetic and logic operations.
ALU or Arithmetic Logic Unit
This is the component of CPU which are high-speed storage areas that store
temporary results and certain control operations
Registers
This is the part of a computer system that is used for storing data and instruction.
Primary Storage
It’s a storage that is non-volatile
Primary Storage
It’s the amount of instructions and data that can be stored in a primary storage.
Memory Capacity
This storage can only stores data limitedly
Primary Storage
The amount of instructions and data that can be stored by the primary storage is limited.
To store a very large amount of data, most computer systems use ____________.
Secondary Storage
It’s volatile and is cheaper than primary storage.
Secondary Storage
What are the 3 types of Secondary Storage
Magnetic Media
Optical Media
Flash Memory
It is one of the oldest types of magnetic media.
Magnetic tape
Requires a tape reader to read information
Magnetic Media
Data is recorded into it using pinpoint laser beam that burns tiny hole into the surface of
a reflective plastic platter
Optical Media
It’s a type of Secondary storage that is compact and portable.
Flash Memory
it is now being used to replace magnetic diskette
Flash Memory
Computers communicate with the outside world through ________ and ____________.

Computing device
These normally refer to the type of computer that has the fastest computing
engine at a particular time.
Supercomputers
It can be also used for weather forecasting and seismic analysis.
Supercomputers
These computers are widely being used by large enterprises or extensive
computing applications that are accessed by thousands of users.
Mainframes Computers
this are computers that are specifically configured to meet the most demanding technical computing requirements.
Workstations
These computers are relatively small and inexpensive computers that perform the
same functions as mainframe computers, but with limited capabilities.
Minicomputers
This type of computer is used to accomplish specific tasks such as process control
and for scientific and engineering applications.
Minicomputers
This is the most popular single user computer and can be classified as: Desktop
PC, Laptop, and Netbook computers
Microcomputers
This refer to smaller and mobile computers.
