2. Lesson 1
Prepared by: Teacher Mai T. Abrigo
Characteristics of
Computer

3. Interpret the characteristic of each picture.

4. Computer
•It is a machine that you feed data
into.
•These data will be processed based
on the set of instructions given.
•“information processing system”

5. DATA
Data is read and
interpreted
through
instructions
given.
RESULT

6. Example: Computing numbers with the
calculator.
Numbers 100
and 25
Divide the
number 100 by
25. Application:
100/25 =
4

7. •Computer is one of the most
powerful tools existing today.
•It’s characteristics are significant
part of every technology.

8. Characteristics of
Computer

9. Speed
•Computers perform in
an unbelievable
quickness. A computer
can interpret about
three to four million
simple instructions per
second.

10. Accuracy
•A typical computer has an accurate
performance of understanding or
command.
•Inaccuracy may only result due to
human error or poorly designed
instructions and program made by
computer users.

11. Reliability
•Computers are very
dependable. Unlike human, a
computer can perform
repetitive tasks without getting
bored and tired.

12. Versatility
•Provided with appropriate logical steps,
computers are versatile machines.
•They can be used in all types of field –
banking, medicine, entertainment,
transportation, and others.

13. Storage Capacity
•Depending on its type, a computer can store
large volumes of data.
•Computers can store and retrieve information
that users feed into them.
•Every character that is recorded in computer is
expressed in terms of bit, byte, kilobyte,
megabyte, gigabyte, and so on.

14. Hierarchy of Data
Bit Single Binary Digit (1 or 0)
Byte 8 bits
Kilobyte (KB) 1, 024 bytes
Megabyte (MB) 1, 024 kilobytes
Gigabyte (GB) 1, 024 megabytes
Terabyte (TB) 1, 024 gigabytes
Petabyte (PB) 1, 024 terabytes
Exabyte (EB) 1, 024 petabytes
