QUESTIONS WITH ANSWERS GRADED A+
● Network administrator . Answer: 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 . Answer: 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 . Answer: install, configure, and administer
appropriate firewall security to protect the organization's systems and
to work proactively against such intrusions.
● Web administrator (webmaster) . Answer: also known as a
webmaster, but more precisely referred to as a web server
administrator. This role is responsible for maintaining web storages,
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 . Answer: 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 . Answer: 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 . Answer: IPOS

● Parts of the CPU . Answer: ALU
Control Unit
Registers
● Memory . Answer: SCRAM
DRAM
ROM
● I/O Subsystem . Answer: Input Devices
, Output Devices
Storage Devices
● Computer structure . Answer: {CPU (ALU, Control Unit, Registers)
System Bus
Memory(SCRAM, DRAM, ROM)}
I/O Bus
{I/O Subsystem (Input Devices, Output decides, Storage Devices)}
● CPU (Central Processing Unit) . Answer: is the device that not only
executes your programs' instructions, but also commands the various
components in the computer.
● Memory . Answer: stores the program(s) being executed and the
data that each program is using.
short-term and long-term storage.
● I/O subsystem . Answer: subsystem includes all peripheral devices
(input, output, storage, network) where storage consists of the long-
term storage devices (disk drives, tape).
● bus . Answer: is the device that permits information to move
between each component.
● The system unit . Answer: is a core feature of notebooks, tablets,
smartphones, and other types of computers; therefore, it comes in a
variety of shapes and sizes. The system unit contains various
