Introductory Message
Welcome to STVEP 7 – (Internet and Computing Fundamentals)!
The Learning Activity Sheet is a product of the collaborative efforts of the
Schools Division of Iloilo and DepEd Regional Office VI - Western Visayas through the
Curriculum and Learning Management Division (CLMD). This is developed to guide
the learning facilitators (teachers, parents and responsible adults) in helping the
learners meet the standards set by the K to 12 Basic Education Curriculum.
The Learning Activity Sheet is self-directed instructional materials aimed to
guide the learners in accomplishing activities at their own pace and time using the
contextualized resources in the community. This will also assist the learners in
acquiring the lifelong learning skills, knowledge and attitudes for productivity and
employment.
For learning facilitator:
The STVEP 7 – (Internet and Computing Fundamentals) Learning Activity
Sheet will help you facilitate the teaching-learning activities specified in each
Competency with minimal or no face-to-face encounter between you and learner. This
will be made available to the learners with the references/links to ease the independent
learning.
For the learner:
The STVEP 7 – (Internet and Computing Fundamentals) Learning Activity
Sheet is developed to help you continue learning even if you are not in school. This
learning material provides you with meaningful and engaging activities for independent
learning. Being an active learner, carefully read and understand the instructions then
perform the activities and answer the assessments. This will be returned to your
facilitator on the agreed schedule.

Background Information for Learners
Types of Computers
A computer is one of the most brilliant inventions of mankind. Thanks to the
computer technology, we were able to achieve an efficient storage and processing of
data; we could rest our brains by employing computer memory capacities for storage
of the information. Owing to computers, we have been able to speed up daily work,
carry out critical transactions and achieve accuracy and precision in work output. The
computers of the earlier years were of the size of a large room and were required to
consume huge amounts of electric power. However, with the advancing technology,
computers have shrunk to the size of a small watch. Depending on the processing
powers and sizes of computers, they have been classified into various types. Let us
look at the classification of computers.
Based on the operational principle of computers, they are categorized as
analog computers and hybrid computers.
Analog Computers: These are almost
extinct today. These are different from a
digital computer because an analog
computer
can
perform
several
mathematical operations simultaneously.
They use continuous variables for
mathematical operations and utilizes
mechanical or electrical energy.
Hybrid Computers: These computers
are a combination of both digital and
analog computers. In this type of
computers, the digital segments perform
process control by conversion of analog
signals to digital ones.

RO6_Q1_STVEP7_LO1
Mainframe
Computers:
Large
organizations use mainframes for highly
critical applications such as bulk data
processing and ERP. Most of the
mainframe
computers
have
the
capacities to host multiple operating
systems and operate as a number of
virtual machines and can thus substitute
for several small servers.
Microcomputers: A computer with a
microprocessor and its central processing
unit is known as a microcomputer. They
do not occupy space as much as
mainframes. When supplemented with a
keyboard and a mouse, microcomputers
can be called as personal computers. A
monitor, a keyboard, and other similar
input-output devices,
Computer memory in the form of RAM
and a power supply unit come packaged
in a microcomputer. These computers
can fit on desks or tables and serve as the
best choices for single-user tasks.
Personal computers come in a variety of
forms such as desktops, laptops, and
personal digital assistants. Let us look at
each of these types of computers.
Desktops: A desktop is intended to be
used on a single location. The spare parts
of a desktop computer are readily
available at relative lower costs. Power
consumption is not as critical as that in
laptops. Desktops are widely popular for
daily use in workplaces and households.
Laptops: Similar in operation to
desktops,
laptop
computers
are
miniaturized and optimized for mobile
use. Laptops run on a single battery or an
external adapter that charges the
computer batteries. They are enabled
with an inbuilt keyboard, touch pad acting
as a mouse, and a liquid crystal display.
Its portability and capacity to operate on
battery power have served as a boon for
mobile users.

RO6_Q1_STVEP7_LO1
Personal Digital Assistants (PDAs): It
is a handheld computer and popularly
known as a palmtop. It has a touch screen
and a memory card for the storage of
data. PDAs can also be effectively used
as portable audio players, web browsers,
and smart phones. Most of them can
access the Internet by means of
Bluetooth or Wi-Fi communication
Minicomputers: In terms of size and
processing capacity, minicomputers lie in
between
mainframes
and
microcomputers. Minicomputers are also
called
mid-range
systems
or
workstations. The term began to be
popularly used in the 1960s to refer to
relatively smaller third generation
computers. They took up the space that
would be needed for a refrigerator or two
and used transistor and core memory
technologies.
The
12-bit
PDP-8
minicomputer of the Digital Equipment
Corporation was the first successful
minicomputer.
Supercomputers:
The
highly
calculation-intensive tasks can be
effectively performed by means of
supercomputers.
Quantum
physics,
mechanics,
weather
forecasting,
molecular theory are best studied by
means of supercomputers. Their ability of
parallel processing and their welldesigned memory hierarchy give the
supercomputers
large
transaction
processing powers.

RO6_Q1_STVEP7_LO1
Wearable Computers: A record-setting
step in the evolution of computers was the
creation of wearable computers. These
computers can be worn on the body and
are often used in the study of behavior
modeling and human health. Military and
health professionals have incorporated
wearable computers into their daily
routine, as a part of such studies. When
the users’ hands and sensory organs are
engaged in other activities, wearable
computers are of great help in tracking
human actions. Wearable computers are
consistently in operation as they do not
have to be turned on and off and are
constantly interacting with the user.
These are some of the different types of computers available today. Looking at
the rate of the advancement in technology, we can definitely look forward to many
more types of computers in the near future.
