Answer: b
Section 1.2 Computers and the Internet in
Industry and Research
1. Which of the following statements is false?
a. Cloud computing allows you to use software, hardware and information stored on
remote computers via the Internet and available on demand—rather than having it stored
on your personal computer.
b. Electronic health records enable health care providers to share patients’ information
across a secure network, improving patient care, reducing the probability of error and
increasing overall efficiency of the health care system.
c. Global Positioning System (GPS) devices a single satellite to retrieve location-based
information.
d. The Human Genome Project was founded to identify and analyze the 20,000+ genes in
human DNA.
ANS: c. Global Positioning System (GPS) devices use a network of satellites to
retrieve location-based information.
2. Which of the following statements is false?
,a. Cloud computing allows you to use software, hardware and information stored in the
“cloud”—i.e., accessed on remote computers via the Internet and available on demand—
rather than having it stored on your personal computer.
b. Cloud computing services allow you to increase or decrease resources to meet your
needs at any given time, so they can be more cost effective than purchasing expensive
hardware to ensure that you have enough storage and processing power to meet your
needs at their peak levels.
c. Businesses using cloud computing services must still manage the applications, which
can be costly.
d. Both (a) and (c).
ANS: c. Businesses using cloud computing services must still manage the
applications, which can be costly. Actually, using cloud computing services shifts the
burden of managing applications from the business to the service provider, saving
businesses money.
3. Microsoft’s ________ is a cloud computing platform that allows you to develop, manage and
distribute your apps in the cloud.
a) Common Language Runtime
b) Windows Azure
c) virtual machine
d) Windows 8
Answer: b

d) Both (a) and (c).
Answer: c. Actually, using cloud computing services shifts the burden of managing
applications from the business to the service provider, saving businesses money.
1.3 Hardware and Software
1. The cost of computing power and communications bandwidth has been
a) about the same each year.
b) going up.
c) going down.
d) undetermined.
Answer: c
1.3.1 Moore's Law
1. ______ Law states that every year or two, the computing power of computers doubles
without any increase in price.
a) Gate’s
b) Moore’s
c) Henderson’s
d) None of the above.
Answer: b
1.3.2 Computer Organization
1. Every computer can be divided into 6 basic units. They are:
a) monitor, mouse, keyboard, hard drive, processor and disk drives.
, b) input, output, primary storage, secondary storage, memory and ALU.
c) input, output, memory, ALU, CPU and secondary storage.
d) input, output, primary storage, secondary storage, CPU, memory.
Answer: c
2. The purpose of the ALU is:
a) to store permanent data.
b) to store temporary data.
c) to cool the computer down and prevent overheating.
d) to perform basic math and logical comparisons for the computer.
Answer: d
3. (True/False) Input devices allow the computer to receive data. They are things such as a
keyboard or mouse.
Answer: True.
4. (True/False) The CPU is the heart of the computer. It tells the computer when input is
received and when output should be displayed. It also helps in the storage of data to
memory.
Answer: True.
5. (True/False) Secondary storage stores data for large amounts of time.
Answer: True.
6. (True/False) Logical decisions are made by the CPU.
Answer: False. Logical decisions are made by the Arithmetic Logic Unit (ALU).
