D322 - Introduction to IT - Final Exam Study Guide.
Administration - An administrator is in charge of some portion of the IT infrastructure
Network administrator - oversees all aspects of the computer network. The network
administrator's duties
include physically laying down cable, making connections, and working with the network
hardware (for
instance, routers and switches).
Database administrator - focus on the design, development, and support of database
management systems
(DBMSs). Tasks will include installation, maintenance, performance analysis, and
troubleshooting as with the
other administrative areas
Security administrator - install, configure, and administer appropriate firewall security to
protect the
organization's systems and to work proactively against such intrusions.
Web administrator - also known as a webmaster, but more precisely referred to as a web
server administrator.
This role is responsible for maintaining web storage, which differs from the development of
web storage.
Specifically, the web administrator must install, configure, maintain, secure, and
troubleshoot the web server.
Define Information Technology: - IT is a term used to describe several aspects: the task of
gathering data and processing it into information, the
ability to disseminate information using technology, the technology itself that permits these
tasks, and the
collection of people who are in charge of maintaining the IT infrastructure (the computers,
the networks, and
, the operating systems). Generically, we will consider IT to be the technology used in
creating, maintaining, and
making information accessible. In other words, IT combines people with computing
resources, software, data,
and computer networks.
Information technology - describes the technology infrastructure that may support
information systems,
although Information Technology could also support many other types of systems (e.g.,
telecommunications
systems). Information Technology includes hardware, software, networks, and databases
that work together to
allow an organization to manage data and information.
A computer performs four operations: - input, processing, output, storage
Computer structure: -
CPU - the device that not only executes your programs' instructions, but also commands the
various
components in the computer.
Memory - stores the program(s) being executed and the data that each program is

using.
I/O - includes all peripheral devices (input, output, storage, network) where storage
consists of the long-term storage devices (disk drives, tape).
bus - the device that permits information to move between each component
system unit - Critical component of all computer based systems; consists of most of the
hardware the computer needs in order to run; comes in a variety of shapes and sizes.
Dynamic RAM (DRAM) - typically called main memory
