10+ Interview Questions and Answers

There are two types of transformers: step-up and step-down. They work by using electromagnetic induction to transfer energy between circuits.

• Step-up transformers increase voltage while decreasing current

• Step-down transformers decrease voltage while increasing current

• Transformers work by passing alternating current through a primary coil, creating a magnetic field that induces a current in a secondary coil

• The ratio of turns in the primary and secondary coils determines the vol...read more

Diodes and transistors are electronic components used in circuits to control the flow of current.

• Diodes are used to allow current to flow in only one direction, while blocking it in the opposite direction.

• Transistors are used to amplify or switch electronic signals.

• There are different types of diodes such as Zener diodes, Schottky diodes, and LED diodes.

• Transistors can be classified as bipolar junction transistors (BJTs) or field-effect transistors (FETs).

• BJTs are used for am...read more

Optical fibre is a thin, flexible, transparent fibre made of glass or plastic that transmits light signals over long distances.

• Optical fibre is used in telecommunications to transmit data over long distances.

• It works by transmitting light signals through the fibre, which bounce off the walls of the fibre and travel to the other end.

• Optical fibre is faster and more reliable than traditional copper wire.

• It is also used in medical equipment, such as endoscopes, to transmit image...read more

An amplifier is an electronic device that increases the amplitude of a signal.

• Amplifiers are used in audio systems to increase the volume of sound.

• They can also be used in radio and television broadcasting to increase the strength of the signal.

• There are different types of amplifiers, such as transistor amplifiers and vacuum tube amplifiers.

• Amplifiers can have different classes of operation, such as Class A, Class B, and Class AB.

• The gain of an amplifier is the ratio of the o...read more

A router is a networking device that forwards data packets between computer networks. A switch is a networking device that connects devices together on a computer network.

• A router connects multiple networks and determines the best path for data to travel between them.

• A switch connects devices on a network and directs data to the correct device.

• Routers use IP addresses to route data, while switches use MAC addresses to direct data.

• Examples of routers include Cisco, Netgear, an...read more

There are several types of printers available in the market.

• Inkjet printers

• Laser printers

• Dot matrix printers

• 3D printers

• Thermal printers

• Dye-sublimation printers

OSI (Open Systems Interconnection) layer is a conceptual model that describes the communication functions of a telecommunication or computing system.

• OSI layer is divided into 7 layers

• Each layer has a specific function and communicates with the layer above and below it

• The layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application

• Example: HTTP operates at the Application layer, while TCP operates at the Transport layer

SCCM client is a software agent installed on devices to manage and deploy software, updates, and configurations remotely.

• SCCM stands for System Center Configuration Manager.

• The client is installed on devices to enable remote management.

• It allows for software deployment, updates, and configuration management.

• SCCM client communicates with the SCCM server to receive instructions and report back.

• It can be used to manage Windows, Mac, and Linux devices.

Provide timely updates, offer alternative solutions, show empathy, and follow up after resolution.

• Communicate regularly with the customer to provide updates on progress.

• Offer alternative solutions or workarounds to minimize downtime.

• Show empathy and understanding towards the customer's frustration.

• Follow up with the customer after the issue is resolved to ensure satisfaction.

I have experience with programming languages such as Java, Python, and C++.

• Java

• Python

• C++

Motherboard is the main circuit board of a computer that connects all the components together.

• It contains the CPU socket, RAM slots, expansion slots, and other connectors.

• It provides power to the components and allows communication between them.

• It determines the compatibility of the components that can be used with the computer.

• Examples of motherboard manufacturers are ASUS, Gigabyte, MSI, and ASRock.

A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).

• Rectifiers are commonly used in power supplies to convert AC voltage to DC voltage.

• They are made up of diodes, which allow current to flow in only one direction.

• Rectifiers can be half-wave or full-wave, depending on the number of diodes used.

• Examples of rectifiers include bridge rectifiers, vacuum tube rectifiers, and solid-state rectifiers.
