What is CIA and why is it important? - CORRECT ANSWER Confidentiality, Integrity,
and Availability (CIA) of data and services
The CIA framework serves to outline the goals and objectives of the security program
and helps organizations defend against threats
What is the role/purpose of a System Administrator? - CORRECT ANSWER Maintains
all aspects of the system including hardware, software, and programming.
What is the role/purpose of a Database Administrator? - CORRECT ANSWER Focuses
on the design, development, and support of database management systems (DBMSs).
What is the role/purpose of a Web Administrator? - CORRECT ANSWER Installs,
configures, maintains, secures, and troubleshoots web severs.
What is the role/purpose of a Network Administrator? - CORRECT ANSWER
responsibility of working with routers and switches
In charge of all aspects of the computer network
Which administrator role/purpose is responsible for administering hardware within your
work environment? - CORRECT ANSWER Systems administrators are also
responsible for upgrading system components and installing and troubleshooting
hardware and software. Also known as Sysadmins, Systems Administrators are also
responsible for developing system security policies and procedures.
What is Data vs. Information? - CORRECT ANSWER data is basically a collection of
unorganized characters that do not convey meaning. Information is data that is given
context and meaning. Ex. Numbers are GPA. GPA coupled with name gives meaning.
What is Information Systems vs. Information Technology? - CORRECT ANSWER The
difference between information systems and information technology is that information
system incorporates the technology, people, and processes involved with information.
Information technology is the design and implementation of information, or data, within
the information system.
,What are the characteristics of quality data? - CORRECT ANSWER Relevance - the
data being used must apply directly to the decision being made
Timely - data must be efficient and must be provided in a timely manner
Thorough - the data must be complete
Accurate - data should be captured only once, where possible and should be captured
as close to the point of activity as possible.
Reliable - data should reflect stable and consistent data collection processes across
collections points and over time
What is the purpose of I/O Subsystems? - CORRECT ANSWER The I/O (Input/output)
subsystem of a computer provides communication between the central system and the
outside environment. It handles all the input- output operations of the computer system.
Peripheral Devices. Input or output devices that are connected to computer are called
peripheral devices.
What is IPSO - Input, Process, Output, Storage? - CORRECT ANSWER Input: Raw
data is entered by the user.
Processing: Raw data is organized or structured for usefulness.
Output: Information is output so user can see results.
Storage: Processed information is stored for permanent record.
What is Hardware vs. Software? - CORRECT ANSWER When it comes to computers,
the hardware is the physical and tangible part, like the monitor, keyboard, and speakers.
Software is the programs and operating systems that need to be installed.
What is a Network? - CORRECT ANSWER A collection of computers and resources
connected by various media so that they can communicate with each other.
What are End-Users? - CORRECT ANSWER the person who actually uses a particular
product.
Identify the ingredients of a computer system. - CORRECT ANSWER CPU, Memory
and Storage, Peripheral Devices
What is the purpose of a CPU? - CORRECT ANSWER Executes programs' instructions
and commands various components in the computer. Referred to as the "chip".
What are the four parts of a computer? - CORRECT ANSWER Motherboard, cpu, Hard
Drives and RAM
What is the purpose of RAM? - CORRECT ANSWER Stands for Random Access
Memory. It temporarily stores data before it is processed and sent to your screen or
printer. It is volatile (means data or information stored disappears when the computer is
turned off or loses power). You can choose the amount of RAM your computer has.
, What is the purpose of Expansion Slots vs. Motherboard Components? - CORRECT
ANSWER The purpose of adding an expansion card or board to a computer's
motherboard is to add or expand some sort of functionality to the computer that it did
not have before. Expansion cards are a way to upgrade a computer. The motherboard
provides basic functionality but the expansion card offers additional or enhanced ports.
What are the types of Memory (RAM/ROM) - volatile vs. nonvolatile? - CORRECT
ANSWER RAM, which stands for random access memory, and ROM, which stands for
read-only memory, are both present in your computer. RAM is volatile memory that
temporarily stores the files you are working on. ROM is non-volatile memory that
permanently stores instructions for your computer.
Volatile memory is the type of memory in which data is lost as it is powered-off. Non-
volatile memory is the type of memory in which data remains stored even if it is
powered-off.
What is the purpose of the BIOS? - CORRECT ANSWER BIOS stands for Basic Input
Output System;Typically stored in ROM chip on the motherboard.Is software not
hardware, ("basic" operating system that runs when the computer is first turned
on).Runs tests of memory and the CPU and initializes hardware components so that the
actual Operating System can be loaded from the hard disk.Can't choose the amount or
contents.
What is the purpose of a hard drive? - CORRECT ANSWER Provide Permanent
storage that is used to hold data and programs
What is the purpose of a motherboard? - CORRECT ANSWER The main circuit board
of a computer; it holds and allows communication between many electronic system
components, such as the CPU and memory, and provides connectors for other
peripherals.
Module 7: The History of the Computer. - CORRECT ANSWER 1st Generation of
Computers
Vacuum tubes, relay switches, the need to program in machine language
2nd Generation of Computers
Transistor components, magnetic core memory, smaller size, easier to program, disk
drives and drums, called mainframe computers
3rd Generation of Computers
Silicon chips (known as ICs - integrated circuits), reduced cost, called mini computers,
networks introduced via dumb terminals
4th Generation of Computers
Single chip processor, called microcomputer, first personal computer, rudimentary
computer graphics, home use
What is a Local vs. a Remote network? - CORRECT ANSWER Local files reside on
your system, while remote files reside on a file server or at another node with which you
