Smart Enovations Interview Questions and Answers

The CPU (Central Processing Unit) is the brain of a computer, responsible for executing instructions and performing calculations.

• The CPU consists of several parts, including the control unit, arithmetic logic unit (ALU), and registers.

• The control unit manages the flow of data and instructions within the CPU and coordinates with other hardware components.

• The ALU performs arithmetic and logical operations, such as addition, subtraction, and comparison.

• Registers are small, high-...read more

A router is a networking device that forwards data packets between computer networks. A hub is a device that connects multiple Ethernet devices together. A switch is a networking device that connects devices on a computer network. A lane refers to a physical or logical channel for data transmission. Basic commands include configuring network settings, troubleshooting connectivity issues, and managing network devices.

OSI LAYER, TCP/IP, DNS, and IP are all fundamental concepts in computer networking.

• OSI LAYER is a conceptual model that describes how data is transmitted over a network.

• TCP/IP is a set of protocols that govern how data is transmitted over the internet.

• DNS is a system that translates domain names into IP addresses.

• IP is a protocol that governs how data is transmitted over a network.

A multimeter is a tool used to measure electrical values such as voltage, current, and resistance.

• Select the appropriate measurement function on the multimeter

• Connect the probes to the circuit or component being measured

• Read the measurement value on the multimeter display

• Ensure the measurement value is within the expected range for the circuit or component

• Turn off the multimeter and disconnect the probes when finished

A multimeter is a device used to measure voltage, current, and resistance in electrical circuits.

• A multimeter typically has a display screen, dial or buttons to select the type of measurement, and probes to connect to the circuit

• It can measure AC and DC voltage, current, resistance, continuity, and sometimes other parameters like capacitance and frequency

• Multimeters are commonly used by electricians, engineers, and technicians to troubleshoot and test electrical circuits
