INTRODUCTION TO IT FINAL EXAM WITH THE LATEST UPDATE
AND BEST GRADED WITH ALREADY CORRECT QUESTIONS AND
ANSWERS
Information Technology - answer-includes hardware, software, networks, and databases that
work together to allow an organization to manage data and information.
Knowledge - answer-is a more vague concept than either information or data. Knowledge is
sometimes defined as information that has been put to use. In other cases, knowledge is a
synthesis of several different sources of information. One way to think of knowledge is that it is
information placed into a context, perhaps the result of experience gained from using
information.
Wisdom - answer-can only come by having both knowledge and experience.
Sharing of resources
Facilitating the integration of departments
Management of information
Securing company and employee information
Ensuring that the organization runs according to
ethical practices
Information Technology - answer-used in creating, maintaining, and making information
accessible as well as the people who supply and support the use and integration of Information
Technology in an organization.

System Administrator - answer-is the process of maintaining the operating system of a
computer system. Requires installing software, making it available, troubleshooting problems
that arise during usage, and making sure that the software is running efficiently. Installing new
hardware and troubleshooting existing hardware. This may or may not include low-level tasks
such as repairing components and laying network cable. It may also require installing device
driver software whenever new hardware is added.
shell scripts - answer-used by an administrator to automate a process
IT is a System - answer-IT can be viewed as a system. We will define a system as combination of
independent parts all working together to accomplish a certain goal.
Core Components of IT - answer-Hardware, Software, and People
IT - answer-Supports Business
Supports Business - answer-Communication, both internal and external
Common tasks of a system administrator include: - answer-Account management: creating new
user accounts and deleting obsolete user accounts
Password management: making sure that all users have passwords that agree with the security
policy
File protection management: making sure that files are appropriately protected (for instance,
making sure that important documents are not writable by the outside world) and performing
timely backups of the file system
Installing and configuring new hardware and troubleshooting hardware including the network
, 3
Installing and configuring new software including updating new operating system (OS) patches,
and troubleshooting software
Providing documentation, support, and training for computer users
Performing system-level programming as necessary (usually through scripting languages rather
than writing large-scale applications or systems software)
Security: installing and maintaining a firewall, examining log files to see if there are any odd
patterns of attempted logins, and examining suspicious processes that perhaps should not be
running
Network Administrator - answer-is in charge of all aspects of the computer network. The
network administrator's duties will include physically laying down cable, making connections,
and working with the network hardware (for instance, routers and switches).
They will also have to configure the individual machines to be able to communicate via the
network.
Troubleshooting the network
Database Administrator - answer-focus on the design, development, and support of database
management systems (DBMSs). Tasks will include installation, maintenance, performance
analysis, and troubleshooting
There are specific applications, performance tuning parameters, account creation, and
procedures associated with the DBMS
, 4
Security Administrator - answer-administrator must stay informed of the many different types of
attacks, such as denial of service attacks on web servers, IP spoofing to intercept messages, and
buffer overflow that allows a hacker to invade computer memory with their own code.
Web Administrator - answer-is responsible for maintaining websites. This responsibility differs
from the development of websites. Specifically, the web administrator must install, configure,
maintain, secure, and troubleshoot the web server.
To be an IT person, you do not necessarily have - answer-to have the rigorous mathematical or
engineering background of computer scientists and computer engineers; there are many
overlapping talents. Perhaps the most important talent is to have troubleshooting skills.
Information is - answer-the removal or limitation of uncertainty. You can usually achieve that if
you have sufficient data.
Information - answer-You can use to bring insight into an organization to remove uncertainty
about behaviors or how your application is being used or what patterns are emerging, that's
where the data becomes information.
the computer science degree - answer-has always heavily revolved around programming, and
the IT degree may require less of it.
engineering technology - answer-approach that concentrates on hardware—circuit boards, disk
drives, PC construction and troubleshooting, physical aspects of networking. There is less
emphasis on programming, although there is still a programming component.
computer systems - answer-This course follows this idea by presenting first the hardware of the
computer system and then the operating systems. We also look at computer networks,
programming, and computer storage to have a well-rounded understanding of the technology
side to IT.
