Video Lecture Notes Review: AI, HTML, Ergonomics, VR/AR, Edge Computing

A set of Q&A flashcards covering HTML basics, AI/ML concepts, ergonomics for computer use, and related technologies described in the notes.

What does HTML stand for?

HyperText Markup Language.

What is the role of HTML in web browsers?

A markup language used to structure and present content on web pages; DOCTYPE declares the HTML version.

What is Artificial Intelligence (AI)?

A computer system built to mimic human intelligence and perform tasks such as recognition of images, speech or patterns, and decision making.

What is Machine Learning (ML)?

A subset of AI where computer systems learn from data to perform tasks they are not explicitly programmed to do.

How do AI and ML differ?

AI is the broader field; ML focuses on learning from data to discover patterns, enabling tasks without explicit programming.

What is Robotic Process Automation (RPA)?

Software that automates business processes such as interpreting applications, processing transactions, handling data, and replying to emails.

What is Edge Computing?

Data is processed by the device or local server rather than transmitted to a data center.

What is Virtual Reality (VR)?

VR immerses the user in a computer-generated environment.

What is Augmented Reality (AR)?

AR enhances the real environment by overlaying digital information.

What are the two types of learning?

Supervised and unsupervised learning.

What is Computer Vision Syndrome (CVS)?

A group of eye- and vision-related problems from prolonged computer use, including dry eyes, eyestrain, blurred vision, headaches, neck/back pain, and carpal tunnel syndrome.

What does ergonomics mean in computing?

Designing and adjusting workstations to reduce risks like CVS, neck/back pain, and carpal tunnel syndrome.

What is the recommended keyboard placement?

Keyboard should be just below elbow level, flat or slightly sloping away, with elbows/arms close to the body and at about a 90-degree angle.

Why use a hands-free headset?

To keep hands free while talking on the phone and reduce strain.

What does declare?

The version of HTML used in the document.

What is the root element of an HTML document?

is the root element that contains all other HTML elements.

What does the element contain?

Metadata, title, links, and scripts; it resides inside before and is not directly displayed.

What does the element hold?

The content of the page that is displayed to the user.

What is the purpose of the

tag?

To denote a paragraph.

Name some common HTML text formatting tags and their effects.

Bold; Strong; Italic; Emphasized; Highlight; Small text; Strikethrough; Inserted text; _{Subscript; ^Superscript.}

What does the

tag represent?

A heading level 1, the top-level heading.
