Usability is the ease of use and learnability of a human-made object. In Software engineering, usability is the degree to which a software can be used by specified consumers to achieve quantified objectives with effectiveness, efficiency, and satisfaction in a quantified context of use.
The object of use can be a software application, website, book, tool, machine, process, or anything a human interacts with. A usability study may be conducted as a primary job function by a usability analyst or as a secondary job function by designers, technical writers, marketing personnel, and others. It is widely used in consumer electronics, communication, and knowledge transfer objects (such as a cookbook, a document or online help) and mechanical objects such as a door handle or a hammer.
Usability includes methods of measuring usability, such as needs analysis and the study of the principles behind an object's perceived efficiency or elegance. In human-computer interaction and computer science, usability studies the elegance and clarity with which the interaction with a computer program or a web site (web usability) is designed. Usability differs from user satisfaction and user experience because usability also considers usefulness.
User Friendly is a daily webcomic about the staff of a small fictional Internet service provider, Columbia Internet. The strip's humor tends to be centered on technology jokes and geek humour.
Drawn and authored by J. D. Frazer, a.k.a. "Illiad", it has been running since November 17, 1997. Frazer is one of the few, and first, webcomic creators successful enough to make a living as an artist. This is probably because it is one of the first webcomics, and was targeted at a specific, tech-related audience, which was already abundant on the Internet at that time.
It is remarkable for having been updated daily from when it started in 1997 until June 2009 (most webcomics are updated only a few times a week), and for having all previous strips online in the archive.
When it is being updated there is a running storyline and sometimes several days' worth of comics are drawn in advance, but the Sunday comic is always drawn for immediate release and breaks from the regular storyline. The Sunday strip is based on current events and is in full color, unlike the regular daily strips.

Our Tara's what people today would call 'user friendly'
She dunno when to say "no"
Her boyfriend, Rupert, 's in insurance
And thinks Ireland should be towed out into the Atlantic
And sunk
He's got a drop of, what I would call, 'boozer friendly'.
He spewed up all over my Belouchi rug
And sobbed apologetically
Saying how he'd given ten pounds to Ethiopia
And bought Band Aid's record
So I let him play with our Tara's remote control unit
'Cause he found it to be very user friendly.
"Ain't you got a computer?", he says, "they're very useful"
"No", I says, "I ain't"
"My bank manager's very helpful" he says
"Is he", I says, "user-er friendly?"
"What about this new weapon the SAS have?" he says
"It fires fifteen rounds a second"
"Yeah", I says, "very user friendly".
"Thank Goodness the miners are back at work", he says
"We couldn't have Scargill getting his way, could we?"
"Loser friendly, just about", I says,
"Never mind, let's get Labour back in
They're much more user friendly"
"What", he says, wiping vomit from his mouth
Fortunately, our Tara had finished cleaning up my rug
"Better take him home", I says
"He's done enough damage for one night:
Oh, and Tara, try and chose more carefully
Who you'd like to be sick at my place next time"
"Sorry", she says, and she meant it.
Boozer friendly.
(User friendly, user friendly,
User friendly, user friendly,
User friendly, user friendly)
