ITS EXAM 1 REVIEW
Course Into/ Why Is This (IT) Important? - Answer-Technology enables greater productivity and
profitability through 1) connectivity, 2) decreased cost, and 3) extreme customer segmentation.
Course Intro/ What is being business-ready? - Answer-being technically and tactically proficient in the
knowledge and skill areas that a person engaged in business is expected to know and developing non-
routine cognitive skills.
Course Intro/ What is Non-routine cognitive skill? - Answer-is the ability and capacity to carry out
cognitively challenging processes and be able to use one's knowledge in a responsible way to achieve a
goal.
Course Intro/ Non-routine cognitive skill -Systems Thinking: - Answer-The ability to model the
components of the system to connect the inputs and outputs among those components into a sensible
whole that reflects the structure and dynamics of the phenomenon observed.
Course Intro/ Non-routine cognitive skill -Critical Thinking: - Answer-The ability to exercise careful
evaluation in order to determine the authenticity, accuracy, worth, validity, or value of something.
Course Intro/ Non-routine cognitive skill -Social Skills: - Answer-Skills needed to successfully interact
with those around you, particularly the ability to persuade and negotiate.
Course Intro/ Non-routine cognitive skill - Life Long Learning: - Answer-The willingness to pursue
knowledge beyond formal schooling.
Course Intro/ data needs to be: - Answer-Data and information are not the same thing; information only
exists as a function of human perception
,1) Accurate,
2) Timely,
3) Relevant,
4) Just sufficient,
5) Worth its cost.
Course Intro/ What is information systems (IS) ? - Answer-integrated set of components for collecting,
storing, and processing data and for providing information, knowledge, and digital product.
Course Intro/ An IS is composed of five (5) components: - Answer-1) Hardware,
2) Software,
3) Data,
4) Procedures, and
5) People.
Comp Sci. 101 / Analog computers: - Answer-1) operate on a continuum of values,
2) the quantities of interest are represented by physical parameters, and
3) they are designed to solve one problem.
Comp Sci. 101/ Digital computers: - Answer-1) use discrete values,
2) the quantities of interest are symbols, and
3) they can solve a multitude of problems.
Comp Sci. 101/ 5 Basic Operations -Inputting - Answer-The operation performed by the Input Unit and
involves feeding instructions and data to the computer. Inputs come from various sources, including the
keyboard, mouse, the computer's hard drive, memory, and data incoming from a network through a
, network (wired or wireless) interface card, and ultimately involves encoding data to a binary format
usable by the computer.
Comp Sci. 101/ 5 Basic Operations -Outputting - Answer-Sending binary data via the Output Unit to
some component, whether it's the computer's RAM or hard drive, or in some cases decoding it via a
graphics processing unit (GPU) so that it's human-readable on a video screen, through an audio card to
make it understandable on speakers, or to a printer.
Comp Sci. 101/ 5 Basic Operations -Storing - Answer-A process managed by the Storage Unit. Before
data can be processed, it needs to be stored or held in memory.
Comp Sci. 101/ 5 Basic Operations -Processing - Answer-Where the so-called "thinking" is done, and it's
performed by the Arithmetic and Logic Unit (ALU) on a computer's CPU. The ALU takes in inputs, does all
the math, performs all the instructions given to it by the program being executed, and outputs data that
is to be used by the program, a component of the computer, the user, or all of the aforementioned all at
once.
Comp Sci. 101/ 5 Basic Operations -Controlling: - Answer-Done by the Control Unit (CU). If the ALU is the
brain, the CU is the rest of the central nervous system, as it directs the operation of the I/O Unit and ALU
by providing timing and control signals.
Comp Sci. 101/ The 5 basic operations occur: - Answer-using a four (4) step cycle called the
1.) Fetch
2.) Decode
3.) Execute
4.) Store cycle, otherwise known as the machine cycle
Comp Sci. 101/ What is Fetch? - Answer-The first step in the cycle involves the CPU retrieving an
instruction from memory.
Course Into/ Why Is This (IT) Important? - Answer-Technology enables greater productivity and
profitability through 1) connectivity, 2) decreased cost, and 3) extreme customer segmentation.
