Sharing of resources
Facilitating the integration of Departments
Management of Information
Ensuring that the organization runs according to ethical practices

Describe trouble shooting (IT Skill)✔️✔️✔️ANS→Detect and diagnose a problem, then find a
solution. Examples: Poor processor performance, full hard drive, virus or other malware.
Describe knowledge of OS's (IT Skill)✔️✔️✔️ANS→Operating system installation, application
software installation, user account creation, system monitoring. Examples: versions of Windows, Mac
OS, Linux, Unix, etc.
Describe system level programming (IT Skill)✔️✔️✔️ANS→Shell scripts to automate processes,
manipulating configuration files for system services. Examples: Bash, Csh scripts, Ruby scripts, C/C++
programs
Describe system security (IT Skill)✔️✔️✔️ANS→Ensuring proper system security is in place.
Following or drafting policies for users. Monitoring for threats. Examples: Keeping security patches up to
date, configuring a system firewall, installing anti-malware software, examining log files of evidence of
breaches or attacks.
Describe hardware (IT Skill)✔️✔️✔️ANS→Installing and configuring new hardware.
Troubleshooting, repairing, or replacing defective hardware. Examples: replacing CPUs and disk drives,
connecting network cables to network hubs, switches, routers.
What are some System Administrator duties?✔️✔️✔️ANS→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.
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.
What are some Network Administrator duties?✔️✔️✔️ANS→physically laying down cable.
making connections.
working with the network hardware (for instance, routers and switches).
like the system administrator, the network administrator will edit configuration files, install software
(related to the network), and so forth.
Troubleshooting the network may combine physical troubleshooting (e.g., is a cable bad?) and software
troubleshooting.
There is also a security aspect to the computer network. Both the system administrator and network
administrator may work on system firewalls. Editing configuration files, writing shell scripts, and
installing software and patches will all be part of a network administrators tasks.
Describe a Database Administrator's duties.✔️✔️✔️ANS→Like system administrators, database
administrators have a long list of important responsibilities, but with a 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. There are specific
applications, performance tuning parameters, account creation, and procedures associated with the DBMS
that are separate from those of system administrators and web administrators. The database administrator
may also be involved with the integration of data from older systems to new ones. As many or most
database systems are now available over the Internet (or at least over local area networks), the
administrator must also ensure proper security measures for remote access.
Describe a Security Administrator's duties.✔️✔️✔️ANS→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
, Page 4 of 103
buffer overflow that allows a hacker to invade computer memory with their own code. Although these are
all known forms of attacks, it does not necessarily mean that a system is protected against them. And as
these attacks are known, newer attacks are being thought of. It is the responsibility of the security
administrator to install, configure, and administer appropriate firewall security to protect the
organization's systems and to work proactively against such intrusions.
Describe a Web Administrator's (aka Webmaster) duties.✔️✔️✔️ANS→The web administrator, also
known as a webmaster, but more precisely referred to as a web server administrator, 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. The web server is
software that runs on one or more computers. The web administrator may or may not be responsible for
the hardware. Typically, the web administrator is not a system administrator on that or those computers.
Therefore, the web administrator will have to work with the system administrator on some aspects of
installation and configuration. Securing the web server becomes critical for businesses. Individuals
outside and inside the organization may have reason to access data on the web-server without
authorization thus requiring the need for securing the web server. The web administrator may be required
to set up password files and establish locations where server scripts can be stored and tested. Security may
be implemented directly through the web server software, or added through the operating system, or some
combination. Security issues may be discovered by analyzing log files that are also used for data mining.
What are the two most common support IT roles asides from administrators?✔️✔️✔️ANS→training,
and help desk. Training occurs as needed, but many help desks are available 24/7.
What is information technology?✔️✔️✔️ANS→Task of gathering data and processing it into
information.
The ability to disseminate information using technology.
The technology itself that permits these tasks.
The collection of people who are in charge of maintaining the IT infrastructure (the computers, the
networks, the operating system).
Generic definition of IT.✔️✔️✔️ANS→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.
