Question: Define a router.

Answer: A router is a network device that forwards data packets between computer networks, often used to connect different networks together.

Question: What is a switch in networking?

Answer: A switch is a device used to connect devices within a network, directing data packets to the correct destination based on MAC addresses.

Question: Explain the concept of IP addressing.

Answer: IP addressing is a system used to identify devices on a network with unique numeric addresses, allowing for communication between them.

Question: What is the difference between IPv4 and IPv6?

Answer: IPv4 uses a 32-bit address scheme, allowing for about 4.3 billion unique addresses, while IPv6 uses a 128-bit address scheme, allowing for a much larger number of unique addresses.

Question: What is DNS?

Answer: DNS (Domain Name System) is a system that translates domain names into IP addresses, enabling browsers to load websites.

Question: What is the purpose of a firewall?

Answer: A firewall is a security system designed to monitor and control incoming and outgoing network traffic, protecting against unauthorized access.

Question: Explain the concept of bandwidth in networking.

Answer: Bandwidth refers to the maximum amount of data that can be transmitted over a network connection in a given period.

Question: What are the types of network topologies?

Answer: Common network topologies include bus, star, ring, mesh, and hybrid, each defining the layout and connection pattern of devices in a network.

Question: What is an HTTP protocol?

Answer: HTTP (HyperText Transfer Protocol) is a protocol used for transferring data over the web, enabling browsers to retrieve web pages from servers.

Question: What is the function of a modem?

Answer: A modem converts digital data from a computer into analog signals suitable for transmission over telephone lines and vice versa.

Question: What is a proxy server?

Answer: A proxy server acts as an intermediary between a user’s device and the internet, often used for security, privacy, or content filtering purposes.

Question: What is a VPN?

Answer: A VPN (Virtual Private Network) creates a secure, encrypted connection between a device and a network, often used for secure internet browsing.

Question: What is cloud storage?

Answer: Cloud storage refers to storing data on remote servers that can be accessed via the internet, allowing for data backup and sharing.

Question: What is a network protocol?

Answer: A network protocol is a set of rules that govern data exchange between devices over a network, ensuring compatibility and communication.

Question: Explain the term ‘hacking’.

Answer: Hacking refers to unauthorized access or manipulation of computer systems, often with malicious intent.

Question: What is data encryption?

Answer: Data encryption is the process of converting data into a code to prevent unauthorized access during transmission or storage.

Question: What is a database management system (DBMS)?

Answer: A DBMS is software that helps in the creation, maintenance, and management of databases, ensuring that data can be easily stored, retrieved, and modified.

Question: Define SQL.

Answer: SQL (Structured Query Language) is a standard programming language used for managing and querying relational databases.

Question: What is Ohm’s Law?

Answer: Ohm’s Law states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance.

Question: What are resistors used for?

Answer: Resistors are used to limit or control the flow of electric current in a circuit.

Question: What is a capacitor?

Answer: A capacitor is an electronic component that stores electrical energy temporarily and releases it when needed, typically used for filtering, smoothing, or timing purposes.

Question: What is the function of a transistor?

Answer: A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power.

Question: Explain the working principle of a diode.

Answer: A diode allows current to flow in one direction only, acting as a one-way valve for electrical current, and is used for rectification.

Question: What is a microcontroller?

Answer: A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system, containing a processor, memory, and input/output peripherals.

Question: What is the difference between analog and digital signals?

Answer: Analog signals are continuous and vary over a range, while digital signals are discrete, representing data in binary form.

Question: What is an oscillator?

Answer: An oscillator is an electronic circuit that generates a periodic, oscillating signal, often used in clock generation and signal processing.

Question: What is a logic gate?

Answer: A logic gate is a basic building block of digital circuits, performing logical operations such as AND, OR, and NOT on one or more binary inputs.

Question: What is an op-amp?

Answer: An operational amplifier (op-amp) is a high-gain voltage amplifier used in various electronic circuits, typically for signal amplification, filtering, and integration.

Question: Define a relay.

Answer: A relay is an electrically operated switch used to control a circuit by opening or closing contacts in response to an input signal.

Question: What is an inverter?

Answer: An inverter is an electronic device that converts direct current (DC) into alternating current (AC).

Question: What is a rectifier?

Answer: A rectifier is a device that converts AC to DC, typically using diodes in a circuit.

Question: What is a power supply?

Answer: A power supply provides electrical power to an electronic circuit or device, typically converting AC from a wall outlet to the required DC voltage.

Question: Explain the working of a transformer.

Answer: A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction, commonly used to increase or decrease voltage.

Question: What is a PCB (Printed Circuit Board)?

Answer: A PCB is a board used to mechanically support and electrically connect electronic components, such as resistors and capacitors, using conductive pathways.

Question: What is an RLC circuit?

Answer: An RLC circuit is a circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), used in filtering, oscillation, and signal processing applications.

Question: What is the role of a voltage regulator?

Answer: A voltage regulator maintains a constant output voltage level, ensuring that electronic devices receive the appropriate voltage.

Question: What is a sensor?

Answer: A sensor is a device that detects physical properties such as temperature, light, pressure, or motion, and converts them into an electrical signal.

Question: What is an ammeter?

Answer: An ammeter is an instrument used to measure the current in a circuit, typically in amperes.
