1. This is considered to be the first manual data processing device developed in China in the 2th century BCE.
A. Hieroglyphics
B. Papyrus
C. Printing Press
D. Abacus
The answer is letter D - Abacus.
The abacus, also called a counting frame, is a calculating tool that was in use centuries before the adoption of the written modern numeral system and is still widely used by merchants, traders and clerks in Asia, Africa, and elsewhere.
Note, however, that China is not the only country which developed the Abacus. The list includes Mesopotamia, Egypt, Persia, Greece and many others. However, what is talked about here is the 2th century, the time around which China developed their own version of the Abacus.
Egyptian hieroglyphs or mdw·w-nṯr were a formal writing system used by the ancient Egyptians that combined logographic and alphabetic elements. Egyptians used cursive hieroglyphs for religious literature on papyrus and wood.
Papyrus, on the other hand, is a thin paper-like material made from the pith of the papyrus plant, Cyperus papyrus. It is very popular especially in the world of literature because many ancient texts excavated/found were written in papyri. This includes the New Testament.
Printing Press is a device for evenly printing ink onto a print medium (substrate) such as paper or cloth. The device applies pressure to a print medium that rests on an inked surface made of movable type, thereby transferring the ink.
Notice how similar options A, B and C are to one another. All of them relate to writing while option D talks of counting, mathematics and data processing.
TEST-TAKING SKILL:
[!] Choose the option that is very different from the other three.
2. He is considered to be the Father of Computing because of his contributions to the basic design of computer.
A. John Napier
B. William Oughtred
C. Blaise Pascal
D. Charles Babbage
Many people mistakenly answer C - Blaise Pascal - when confronted with this question. However, remember that Blaise Pascal did not contribute to the design of computers; he contributed basic mathematical computing processes that gave rise to calculators.
Remember: Blaise Pascal = calculator, the syringe and Pascal's Wager (in Christian philosophy)
So, if option C is not correct, which one is? It's letter D - Charles Babbage. Charles Babbage originated the concept of programmable computers. Since he was an engineer and a computer scientist, he devoted most of his life to inventing the first mechanical computer that eventually led to more complex designs.
John Napier is more known for his contributions to logarithm and decimal notation. He also conceptualized the Napier's Bones or Napier's Rods used in the teaching of Mathematics and Languages today.
William Oughtred or Rev. William Oughtred (5 March 1574 – 30 June 1660) was an English mathematician and Anglican minister. After John Napier invented logarithms, and Edmund Gunter created the logarithmic scales (lines, or rules) upon which slide rules are based, it was Oughtred who first used two such scales sliding by one another to perform direct multiplication and division; and he is credited as the inventor of the slide rule in 1622. Oughtred also introduced the "×" symbol for multiplication as well as the abbreviations "sin" and "cos" for the sine and cosine functions
3. A computer system is actually made up of actual machines known as _.
A. Monitor
B. Hardware
C. Printer
D. Software
The answer for this item is option B - hardware.
Notice that both option A - monitor - and option C - printer - are under the umbrella term "hardware." Answering either A or C will overlook the fact that the questions seeks a general term used to refer to "actual machines" that compose "a computer system."
Varieties of software, on the other hand, are not actual machines but are programmed applications and systems used for people to interact with the computer system and get something done.
TEST-TAKING SKILLS:
[!] The correct answer is usually between two directly opposite options.
[!] Eliminate options that are under another umbrella term.
