What are some skills needed by IT personnel?
Troubleshooting and problem solving.
Knowledge of operating systems.
,System level programming.
System security
Hardware
Describe trouble shooting (IT Skill)
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)
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)
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)
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)
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?
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?
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.
