Week 4 Practice Quiz: Internet, Email & Web
Q1: HTTP vs HTTPS
What does the "S" in HTTPS stand for, and why does it matter?
A. "Speed" — HTTPS loads pages faster than HTTP B. "Secure" — HTTPS encrypts data between your browser and the website C. "Server" — HTTPS is only used by web servers, not regular users D. "Simple" — HTTPS is a simplified version of HTTP
Answer: B Explanation: HTTPS stands for HyperText Transfer Protocol Secure. It uses encryption (TLS/SSL) to protect data in transit, preventing attackers from reading information like passwords or credit card numbers as they travel between your browser and the server.
Q2: URL Components
In the URL https://www.example.com/products/shoes?color=red, which part is the domain name?
A. https:// B. www.example.com C. /products/shoes D. ?color=red
Answer: B
Explanation: The domain name (www.example.com) identifies which server to connect to. https:// is the protocol, /products/shoes is the path to a specific page, and ?color=red is a query parameter that passes additional information.
Q3: Email Protocols
Which protocol is used to SEND email from your email client to the mail server?
A. IMAP B. POP3 C. SMTP D. FTP
Answer: C Explanation: SMTP (Simple Mail Transfer Protocol) handles sending outgoing email. IMAP and POP3 are used for receiving/retrieving email from the server. FTP is for file transfers, not email.
Q4: Browser Cookies
What is the primary purpose of cookies in a web browser?
A. To speed up your internet connection B. To store small pieces of data (like login status or preferences) from websites you visit C. To block advertisements on web pages D. To scan websites for viruses before loading them
Answer: B Explanation: Cookies are small text files that websites store on your computer to remember things like your login session, language preferences, or shopping cart contents. They help websites provide a personalized experience across visits.
Q5: Top-Level Domains
What does a Top-Level Domain (TLD) like .edu, .gov, or .org indicate about a website?
A. The speed of the website's server B. The general category or type of organization that owns the domain C. The programming language the website was built with D. The country where the website's users live
Answer: B
Explanation: TLDs indicate the type of organization: .edu for educational institutions, .gov for government agencies, .org for organizations (often nonprofits), and .com for commercial entities. Country-code TLDs (like .uk or .jp) indicate the country.
Q6: Cloud Service Models
A company uses Gmail for email, Dropbox for file storage, and Zoom for video calls — all through web browsers, with no software installed locally. What type of cloud service model is this?
A. IaaS (Infrastructure as a Service) B. PaaS (Platform as a Service) C. SaaS (Software as a Service) D. On-premises computing
Answer: C Explanation: SaaS delivers complete applications over the internet that you use through a browser. Gmail, Dropbox, and Zoom are all SaaS products — the provider handles all the infrastructure, and users just log in and use the software.
Q7: Phishing Basics
Which of the following is the BEST indicator that an email might be a phishing attempt?
A. The email includes the company's official logo B. The email comes from a slightly misspelled domain like "arnazon.com" instead of "amazon.com" C. The email was received during business hours D. The email is written in English
Answer: B Explanation: Phishing emails often use domains that look similar to legitimate ones (like "arnazon" vs "amazon"). Always check the actual sender address carefully. Logos can be copied easily, so the presence of a logo doesn't mean the email is legitimate.
Q8: HTML/CSS/JS Overview
In web development, what are the roles of HTML, CSS, and JavaScript?
A. HTML styles the page, CSS adds interactivity, JavaScript provides structure B. HTML provides structure/content, CSS handles styling/layout, JavaScript adds interactivity/behavior C. They are three competing languages — you only need to learn one D. HTML is for mobile sites, CSS is for desktop sites, JavaScript is for apps
Answer: B Explanation: HTML defines the structure and content of a web page (headings, paragraphs, images). CSS controls the visual presentation (colors, fonts, layout). JavaScript adds interactive behavior (dropdown menus, form validation, dynamic content).
Q9: Email Etiquette
When is it appropriate to use "Reply All" on an email?
A. Always — it's the default and should be used for every response B. Only when your response is relevant to everyone on the original recipient list C. Never — it's considered rude in all professional settings D. Only when the email has fewer than 3 recipients
Answer: B Explanation: "Reply All" sends your response to every recipient of the original email. It should only be used when everyone needs to see your reply. Unnecessary Reply All messages clutter inboxes and are a common workplace annoyance.
Q10: IMAP vs POP3
What is the main advantage of IMAP over POP3 for managing email?
A. IMAP is faster at sending emails B. IMAP keeps emails on the server, so you can access them from multiple devices and they stay in sync C. IMAP blocks spam more effectively than POP3 D. IMAP doesn't require an internet connection
Answer: B Explanation: IMAP (Internet Message Access Protocol) keeps emails on the server and syncs across all your devices. POP3 typically downloads emails to one device and removes them from the server, making multi-device access difficult.
