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. - CORRECT

- file protection management
- installing and configuring new hardware and troubleshooting hardware including
the network
,- 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 - CORRECT ANSWER Common tasks of a system administrator include
is in charge of all aspects of the computer network. The network administrator's
duties include physically laying down cable, making connections, and working

Output
Storage - CORRECT ANSWER A computer performs four operations:
Input-Processing-Output-Storage cycle
how people use a computer
input data (e.g., words, numbers, images, sounds);
the computer converts the data into information, or processes it.
the computer may output the information for the user (e.g., words are displayed
via the monitor or printed on paper, audio is transmitted over speakers) or store
the information for later use.
Whether the information is stored first or output is dependent on the users
needs. - CORRECT ANSWER IPOS
a collection of components that work together to meet the needs of the user.
