5. Process analog data (continuous
data).
Examples include early computing
machines used for scientific and
engineering calculations.
6. Continuous Data ( Measurable)
Definition:
Data that can take any value within a
given range.
measurements can be precise
Measurable, can have fractions or
decimals
Examples: Temperature, height, weight,
time.
8. Process digital data
(discrete data).
A computer that performs
calculations and logical
operations using binary
digits '0' and '1'."
9. Discrete Data (Countable)
Definition:
Data that can only take specific,
distinct values.
Countable, whole numbers only.
•Examples: Number of students in a class,
number of cars in a parking lot, roll of a
dice.
10. Discrete Data (Countable)
Examples
Number of apples in a basket (you can
have 3 or 5 apples, but not 3.5 apples
unless you cut one).
Number of goals scored in a soccer match
(a team can score 2 or 4 goals, but not 2.7
goals).
Number of students in a classroom (you
can count students one by one).
12. Combine features of both analog
and digital computers.
Hybrid computer is a digital
computer that accepts analog
signals, converts them to digital
and processes them in digital form.
15. Supercomputers derive much of
their speed from the use of multiple
processors.
Multiprocessing enables the computers
to perform tasks simultaneously--either
assigning different tasks to each
processing unit or dividing a complex
task among several processing units.
16. used in weather forecasting,
seismic analysis and space
exploration.
They are found in many public and
private research centers, such as
universities and government
laboratories.
17. The speed of modern
supercomputers is measured in
nanoseconds and gigaflop.
A nanosecond is one billionth of a
second.
A gigaflop is one billion floating-point
arithmetic operations per second.
18. The digital component typically
acts as the controller, handling
logical and numerical operations.
The analog component often
functions as a solver, tackling
differential equations and other
mathematically complex problems.
20. A mainframe computer may
contain several microprocessors.
The typical mainframe
computer occupies much of a
large room.
built for heavy loads but not as fast
as supercomputers.
21. Big computers
used by banks,
governments,
and large
companies to
process tons of
data at once.
24. Mid-sized, less powerful than
mainframes but more powerful than
personal computers.
used in businesses and universities for
specialized tasks.
Example: Some hospitals use minicomputers for
managing patient records.
26. They are computers designed to provide
services to client machines in a computer
network.
They have larger storage capacities and
powerful processors.
Running on them are programs that serve
client requests and allocate resources like
memory and time to client machines.
27. Usually they are very large in size, as
they have large processors and many
hard drives.
They are designed to be fail-safe and
resistant to crash
32. It typically has advanced processors,
ample memory, and dedicated
graphics cards.
is a powerful computer designed
for high-performance tasks like
engineering, scientific research,
3D modeling, and video editing.
36. 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.
40. It is a handheld computer and
popularly known as a palmtop.
It has a touch screen and a
memory card for storage of data.
PDAs can also be used as portable
audio players, web browsers and
smart phones.
42. are mobile computers that
are very handy to use.
They use the touch screen
technology. Tablets come
with an onscreen keyboard or
use a stylus or a digital pen.
