WGU C182 Q&A GRADE A +
Application Software - (correct answer)Programs end users run to accomplish tasks.
Productivity Software - (correct answer)Application software used to aid in productivity.
I.E. Presentation software, word processor, spreadsheets.
Internet Usage Software - (correct answer)Email, FTP client, web browser
System Software - (correct answer)Consists of programs that make up the OS and
directly support system itself.
**Includes services or DAEMONS
Server Software - (correct answer)Works with hardware to provide network service.
Local Application - (correct answer)Software stored on an individual computer.
Intranet - (correct answer)A LAN that uses IP. Used to communicate within organization.
Cloud Computing - (correct answer)Allows organization to access resources/app
anywhere, anytime. Beneficial because an org. may access resources it may not
normally have.
Operating Systems - (correct answer)Allows a user to easily access hardware/software,
required to maintain computer environment.
Kernel - (correct answer)Core component of OS.
Loads when computer first boots
Sits on top of hardware, is interface b/w hardware and software.
, Device Drivers - (correct answer)Interface b/w OS and hardware.
Shell - (correct answer)Interface for user, often personalized. The shell provides access
to the kernel.
I.E. The GUI will translate mouse motions into calls to kernel/routines. Desktop
elements include shortcuts, windows theme, menus, background.
Services (Daemons) - (correct answer)OS programs that start when OS is loaded. They
run in the background and wait for an event to initiate.
Utility Programs - (correct answer)Allow user to monitor system performance.
Web Server - (correct answer)Role is to respond to HTTP requests.
*Most HTTP requests are for HTML docs, but could include any web accessible
resource.
It's all combined into the URL.
**APACHE is most popular web server-can execute scripts for dynamic pages, use
security mechanisms, log request for trend tracking.
Proxy Server - (correct answer)Acts as a giant cache and allows pages accessed
frequently in an organization to be accessed locally.
*Also provides degree of anonymity, since IP address recorded is for proxy server and
not individual client.
*Can also be used to block requests to certain servers (i.e Facebook)
*Can reject responses that contain certain content (i.e "porn")
**SQUID is most common, but APACHE can also be used as proxy server.
Database Server - (correct answer)Permits dB access across a network.
Performs tasks such as data analysis, data manipulation, security,and archiving.
