Question 1

What are the essential hardware components inside a desktop computer, and what role does each one play?

Accepted Answer

A desktop computer is made up of several core hardware components, and understanding what each one does is essential for any IT support technician. Being able to identify and explain these parts helps you troubleshoot issues faster and communicate clearly with both users and senior engineers.

The processor, commonly called the CPU, is the brain of the computer. It executes instructions from the operating system and applications. Modern desktops typically use processors from Intel or AMD, and they come with multiple cores that allow the system to handle several tasks at the same time. When a

Question 2

What is the BIOS or UEFI, and what role does it play when a computer starts up?

Accepted Answer

BIOS and UEFI are types of firmware stored on a chip on the motherboard. They are the very first software that runs when you press the power button, and their job is to initialize the hardware, run basic diagnostics, and hand control over to the operating system. Understanding how they work is fundamental for any IT support role because many hardware issues can be diagnosed or resolved through BIOS and UEFI settings.

BIOS stands for Basic Input Output System. It has been around since the early days of personal computing. When the computer powers on, the BIOS performs a process called POST,

Question 3

What is the difference between the Control Panel and the Windows Settings app, and when would you use each one?

Accepted Answer

The Control Panel and the Windows Settings app are both interfaces for configuring the operating system, but they serve slightly different purposes and offer different levels of access. Understanding when to use each one is an everyday skill for IT support technicians.

The Windows Settings app was introduced with Windows 10 as a modern, simplified interface for the most common configuration tasks. It is designed to be touch-friendly and visually clean. You can access it by clicking the Start menu and selecting the gear icon, or by pressing Windows + I. Settings handles everyday tasks like c

Question 4

What is Task Manager, how do you open it, and what are its most useful features for troubleshooting?

Accepted Answer

Task Manager is one of the most important built-in tools in Windows for monitoring system performance and troubleshooting issues. It gives you a real-time view of what is happening on the computer, and it is often the first place an IT support technician should look when a user reports a problem.

You can open Task Manager in several ways. The most common method is pressing Ctrl + Shift + Esc, which opens it directly. You can also press Ctrl + Alt + Delete and select Task Manager from the menu, or right-click the taskbar and choose Task Manager. If the system is unresponsive and the graphica

Question 5

What is an IP address, and what is the difference between a static IP address and a dynamic IP address?

Accepted Answer

An IP address is a unique numerical label assigned to every device connected to a network. It serves two main purposes: identifying the device and providing a location for sending and receiving data. Think of it like a mailing address for your computer. Without an IP address, devices on a network would have no way to find and communicate with each other.

The most common format is IPv4, which uses four groups of numbers separated by dots, such as 192.168.1.25. Each group ranges from 0 to 255. Alongside the IP address, every device also has a subnet mask, which defines which part of the addre

Question 6

What is DNS, and why is it important for network connectivity?

Accepted Answer

DNS stands for Domain Name System, and it is often described as the phonebook of the internet. Its primary job is to translate human-readable domain names, like www.google.com, into numerical IP addresses, like 142.250.80.4, that computers use to locate each other on the network. Without DNS, users would need to memorize IP addresses for every website and service they want to access.

When you type a website address into your browser, your computer first checks its local DNS cache to see if it already knows the corresponding IP address from a recent lookup. If the address is not cached, the

Question 7

What is the typical lifecycle of a support ticket from the moment a user reports an issue to when the ticket is closed?

Accepted Answer

The lifecycle of a support ticket follows a structured series of stages designed to ensure that every issue is tracked, resolved, and documented. Understanding this lifecycle is essential for any help desk technician because it provides the framework for consistent, accountable service delivery.

The lifecycle begins with ticket creation. A user reports an issue through one of several channels: a phone call, an email, a self-service portal, or a chat message. The help desk technician logs the issue in the ticketing system, capturing the user's name, contact information, a description of the

Question 8

What is the difference between an incident and a service request in ITIL, and why does this distinction matter?

Accepted Answer

In ITIL, which stands for Information Technology Infrastructure Library, incidents and service requests are two distinct types of tickets that follow different workflows. Understanding this distinction helps help desk technicians handle each type appropriately and ensures the team's metrics and reporting accurately reflect the work being done.

An incident is an unplanned interruption to an IT service or a reduction in the quality of a service. The key word is "unplanned." Something that was working has stopped working or is performing below expectations. Examples include a user's email clie

Question 9

What is multi-factor authentication, how does it work, and why is it important for security?

Accepted Answer

Multi-factor authentication, commonly abbreviated as MFA, is a security method that requires users to provide two or more forms of verification before they can access an account or system. It adds an extra layer of protection beyond just a password, making it significantly harder for attackers to gain unauthorized access even if they manage to steal or guess the password.

MFA works by combining factors from different categories. The three main categories are something you know, something you have, and something you are. Something you know is a piece of information like a password, PIN, or s

Question 10

What are the most common types of malware, and how would you recognize the symptoms of an infection on a user's workstation?

Accepted Answer

Malware is a broad term for any software designed to harm, exploit, or compromise a computer system. Understanding the different types of malware and recognizing infection symptoms helps IT support technicians respond quickly and limit the damage.

A virus is one of the oldest types of malware. It attaches itself to a legitimate file or program and spreads when that file is shared or executed. Viruses require user action to propagate, such as opening an infected email attachment or running a compromised installer. Once activated, a virus can corrupt files, slow down the system, or delete dat
