Test I: Identification.
Directions: Write the correct answer on the space provided. (2 points each)
Difference Engine 1. The considered first computer in the world.
Solid-state-drive (SSD) 2. A device quite similar to the hard disk, but containing no moving parts and
which stores data in a digital format.
Motherboard 3. It contains different elements as memory, processor, modem, slots for graphic card
and LAN card.
Charles Babbage 4. Who is the Father of modern computer?
Secondary memory 5. A device for medium-term storage of data.
Power supply unit (PSU) 6. It converts alternating current (AC) electric power to low voltage DC
power for the internal components of the computer.
John napier 7. Who invented the logarithms?
Ada lovelace 8. The first computer programmer.
Input Device 9. They are devices that are used to get commands and data into the computer system for
processing.
Adding machine 10. It is a machine that capable of adding numbers and capable of performing
arithmetic functions.
System Software 11. A set of coded instructions that control, coordinate, and initialize the operations
of various units such as keyboard, CPU, monitor, printer, and other devices when the computer is
switched on.
Rambus dynamic ram 12. It is a memory subsystem that promised to transfer up to 1.6 billion bytes
per second.
Keyboard 13. Generally called the Standard Input Unit.
Navigation key 14. These are the cursor-control key that helps you move around the screen.
Software 15. It is a series of instructions or a special program that performs a particular task and is
recorded or stored in the computer memory and cannot be physically touched, flit, or seen.
Good luck and Godless!!!

2. Introduction to Computing_midterm
Test III: True or False.
Directions: Write TRUE if the statement is correct and if not, write FALSE and underline the
word or statement that sentence incorrect. (2 points each)
1. Input devices translate processed information from the computer into a form that we can
understand.
False 2. The operating system controls and manipulates the data that produce information.
False 3. In year 1962 when Blaise Pascal started to establish the calculating machine.
True 4. Raw data is received from an input device immediately after it has been entered by a user and
through data can also be retrieved for processing from a storage device.
True 5. Microprocessor is a computer processor when data processing logic and control is included on
a single integrated circuit.
Test IV. Enumeration. (10 points)
1. Give 5 functions of software? (Based on the notes that I provided)
 It protects the hardware from the damage
 It erases operational in the computer
 it interfaces directly to the user and computer
 it actually measures and determined the system performance
 it interfaces one elements with another
2. Give the 5 functions of hardware? (Based on the notes that I provided)
 Input device – responsible for entering data to the computer system it include mouse,
keyboard etc
 Process – this where the data turned into the information after a process through the process
and conduct of the central processing unit also known as CPU
 Output – the end result of the information that have been display in the user after the
processing
 Storage – this where the information stored in and is capable of retaining data before and after
have been process it include RAM, SSD, HDD and etc
 Control – this is the one responsible for conducting organization and the flow of data that
from central processing unit and this device is primary responsible for the operation in the
control unit portion of the CPU and is responsible for retrieving data from ram and then
transfer to the CPU for processing and then returning it to the storage or memory once is
completely process into the information
