5. WHAT SKILLS, TRAITS AND ATTITUDE WILL
HELP YOU SUCCEED IN THIS COURSE?
• Strong Technical Skills – the knowledge and ability to learn,
operate and control properly and safely an extensive range of
equipment, tools and systems used in the field.
• Computer Literacy – basic knowledge of computer use and
being able to understand application software and systems
• Logical skills – the ability to determine how a system should
work and how changes in conditions, operations, and the
environment will affect outcomes
• Problem solving skills – the ability to identify problems and
review related information to develop and evaluate options
and implement solutions.

6. • Observation skills – the ability to notice and identify even
the most minute problems in a system, process or
equipment
• Basic Mathematical skills – since there are basic
programming concepts included in the study, you need
have basic math to surpass lessons
• Patience – during practicum exercises, you will not
always be able to identify and fix the problem on a
computer, system and parts right away so you have to
extend your patience and continue working.

7. DELIVERY METHODS
• Discussion-demonstration,
• self-paced instruction
• Group discussion
ASSESSMENT METHODS
• Written Test
• Hands-on
• Interview
• Portfolio

8. IS COMPUTER SYSTEM
SERVICING A PROFESSION?
• Computer SYSTEM servicing jobs are
considered professions, because they require a
specialized set of skills and is some cases they
require a TESDA certificate. A specialization in
Computer System Servicing, combined with a
certificate and/or professional experience,
makes one a professional in this field. Common
careers include working as a Computer Service
Technician, Computer Network Serviceman and
Peripheral Service Technician.

10. CONCEPT OF BASIC
COMPUTER

11. COMPUTER
• A machine capable of following instruction to alter data in a
desirable way and to perform at least some of these operations
without human intervention.
• A computer is a programmable machine that receives input,
stores and manipulates data, and provides output in a useful
format.
• Computer was used as an electronic device that allows
inputting data and having it stored, processed, or otherwise
manipulated quickly and efficiently.

12. HISTORY OF COMPUTER
• The repetitive process of computation
leads to people becoming bored in
computing such as navigational table,
tide charts, and planetary positions for
astronomical almanacs. People were
doing these things everyday and this is
the reason why people invented
computers, that is to aid in numerous
computation required everyday.

13. COMPUTING AID THAT
PEOPLE INVENTED
• The Abacus
• The first computing aid that were used to help
them in their computation.

14. • The Napier’s Bone
• An abacus created by John Napier for calculation
of products and quotients of numbers that was
based on Arab mathematics and lattice
multiplication used by Fibonacci writing in the
Liber Abaci.

15. • The Slide Rule
• Used primarily for multiplication and division, and
also for "scientific" functions such as roots,
logarithms and trigonometry, but is not normally
used for addition or subtraction.

16. • The Calculating Clock/ Schickard Calculator
• Consisted of a six-digit machine that could add or
subtract.
• Wilhelm Schickard developed it on 1623 in Tübingen,
Württemberg

17. • The Pascaline
• The first calculator or adding machine to be
produced in any quantity and actually used. It could
only do addition and subtraction, with numbers
being entered by manipulating its dials.
• designed and built by the French mathematician-philosopher Blaise
Pascal between 1642 and 1644

18. • The Step Reckoner
• The first calculator that could perform all four
arithmetic operations: addition, subtraction,
multiplication and division.
• invented by German mathematician and philosopher Gottfried
Wilhelm Leibniz around 1672 and completed 1694

19. • The Difference Engine
• An automatic, mechanical calculator designed to
tabulate polynomial functions.
• By 1822 the English mathematician Charles Babbage who is
considered as Father of the Computer today was proposing a
steam driven calculating machine the size of a room

20. • The Hollerith's Tabulating Machine
• the electro-mechanical tabulator.
• On the tabulator's desk to the right is a press-like device which
would bring an array of pins into contact with a punch card.

21. • The Mark I
• The first large-scale automatic digital computer
the USA by Howard H. Aiken, built at IBM and
shipped to Harvard in February 1944.

22. • The Apple I
• An early personal computer.
• They were designed and hand-built by Steve Wozniak

23. • The PDP-12
• A 12 bit machine introduced in 1969. Applications
included applied psychology, chemistry, patient
monitoring, and industrial testing.

24. • The IBM Personal Computer
• The original version and progenitor of the IBM
compatible hardware platform.

25. • The Personal Computer
• any general-purpose computer whose size,
capabilities, and original sales price make it useful
for individuals, and which is intended to be
operated directly by an end user, with no
intervening computer operator.

26. • Netbooks
• A branch of subnotebooks, a rapidly evolving
category of small, lightweight, and inexpensive
laptop computers suited for general computing
and accessing Web-based applications; they are
often marketed as "companion devices", i.e., to
augment a user's other computer access.
