Which protocol is used for secure communication between web browsers and servers?
- HTTP
- FTP
- HTTPS
- SMTP
Answer: HTTPS
HTTPS (HTTP Secure) encrypts data using SSL/TLS to protect confidentiality and integrity during transmission. Essential for login pages, payments, and sensitive data. HTTP transmits in plaintext. Browsers mark non-HTTPS sites as 'Not Secure'. Fundamental for web security awareness in all government exams.
The Linux command to list all files including hidden ones is ls ________.
- Stratified
- Telecommunication / ITU
- Continuous
- -a
Answer: -a
ls -a lists all files including hidden ones (starting with .). ls -l shows detailed list; ls -h makes sizes human-readable; ls -la combines both. Hidden files store configuration data. Understanding command-line flags is fundamental for Linux administration questions in technical exams.
JavaScript is primarily executed on the server-side in web applications.
- True
- False
Answer: False
JavaScript was designed for client-side execution in web browsers to enable interactive web pages. Server-side JavaScript (Node.js) is possible but not the primary use case. Understanding client-server architecture is fundamental for web technology questions in SSC and banking exams.
The HTML tag used to create a hyperlink is ________.
- P4 / Programmable
- Combined Gas and Gas (COGAG)
- <a>
- Accessibility
Answer: <a>
The anchor tag <a> with href attribute creates hyperlinks in HTML. Example: <a href='https://example.com'>Link</a>. Fundamental for web development basics tested in SSC and Railway exams. Other tags: <img> for images, <p> for paragraphs, <div> for containers.
In Python, lists are mutable while tuples are immutable.
- True
- False
Answer: True
Lists ([]) can be modified after creation: append, remove, change elements. Tuples (()) cannot be changed once created, making them hashable and usable as dictionary keys. Immutability provides safety for fixed data, while mutability offers flexibility for dynamic collections. Choosing appropriately improves code correctness and performance.
Which data type is used to store true/false values in most programming languages?
- int
- char
- boolean
- float
Answer: boolean
Boolean data type represents two values: true or false. Named after George Boole, founder of Boolean algebra. Used in conditional statements, loops, and logical operations. Some languages (C) use integers (0=false, non-zero=true), but modern languages (Java, Python, C#) have dedicated bool type for clarity and type safety.
Ohm's Law states that current through a conductor is directly proportional to voltage and inversely proportional to resistance.
- True
- False
Answer: True
Ohm's Law: I = V/R, where I=current (Amperes), V=voltage (Volts), R=resistance (Ohms). Fundamental for circuit analysis, component selection, and troubleshooting. Applies to ohmic materials at constant temperature. Non-ohmic devices (diodes, transistors) have non-linear V-I characteristics requiring advanced modeling.
Which operator is used to check equality of values in most programming languages?
- =
- ==
- ===
- :=
Answer: ==
Double equals (==) checks value equality in C, Java, Python, JavaScript. Single equals (=) is assignment operator. Triple equals (===) in JavaScript checks value AND type equality. := is assignment in Pascal/Go. Understanding operator precedence and type coercion is crucial for writing correct conditional logic in exams and real code.

PSLV has four stages using solid and liquid propulsion alternately.
- True
- False
Answer: True
PSLV has four stages: 1st and 3rd use solid propellant; 2nd and 4th use liquid propellant. Strap-on solid boosters enhance lift-off thrust. This alternating design optimizes performance for polar and sun-synchronous orbits. PSLV's reliability and versatility made it ISRO's workhorse for earth observation and small satellite launches.
Which platform allows citizens to report grievances related to government services and track resolution status?
- MyGov

The cloud service model where the provider manages infrastructure and platform, while customer manages applications and data, is called ________ as a Service.
- e-Filing
- Responsibility Segregation / CQRS
- Astra
- Platform
Answer: Platform
PaaS (Platform as a Service) provides development platforms (runtime, middleware, OS) managed by provider. Customers deploy and manage applications and data without worrying about infrastructure. Examples: Google App Engine, AWS Elastic Beanstalk, Azure App Service. Contrasts with IaaS (customer manages OS+) and SaaS (provider manages all).
