Today’s IT industry expects freshers to come with more than just academic knowledge. Companies look for candidates who understand practical concepts, basic system operations, SaaS tools, security fundamentals, and the latest trends like AI and automation.
Even if you are not from a computer science background, learning these essentials can significantly improve your confidence, employability, and performance during interviews.
This guide explains the core technology concepts every fresher must know, with simple explanations and real workplace contexts.
1. Office 365 Suite: Daily Tools You Must Understand
Almost every modern company uses Microsoft 365 (O365) for collaboration and communication. Freshers must know the basics of:
Outlook – Email Essentials

- Using SharePoint sites for team collaboration
Why This Matters?
Every fresher will use these tools from Day 1. Knowing them increases your efficiency and reduces dependency on IT support.
2. Local Application Setup: IIS, XAMPP, WAMP & Linux Hosting Basics
Understanding how applications run locally and on servers is crucial.
Windows IIS (Internet Information Services)
Freshers should know:
- How to install and enable IIS
- Hosting a simple website using IIS

Linux Apache Basics
Even minimal knowledge helps:
- Starting/stopping Apache
- File permissions (CHMOD, CHOWN)
- Directory root structure (var/www/html)
Domain & Hosting Control Panels
You must know:
- DNS Records
- A Record → Points domain to server IP
- CNAME → Alias to another domain

- @ record → Root domain mapping
- Name Server changes
- SSL certificate installation
- Subdomain creation
Why This Matters?
Whether you’re in development, support, DevOps, or QA, understanding basic hosting and DNS concepts is essential for troubleshooting.
3. SaaS (Software as a Service): How Cloud Applications Work
Most modern companies use SaaS platforms — from CRM systems to HR tools.
Key Concepts Freshers Should Know
- SaaS runs on the cloud, not on local machines
- Users access it through a browser or mobile app
- No need for installation or manual updates
- Subscription-based payment model

Examples
- Salesforce (CRM)
- Slack / Teams (Communication)
- Zoho / Freshdesk (Support)
- Google Workspace / Office 365
- Canva, Figma, Notion, Shopify
Why This Matters?
Understanding SaaS helps you adapt quickly to new tools, support customers, and appreciate how cloud systems work behind the scenes.
4. Basic Networking: The Foundation of All IT Roles
Every tech fresher should know basic network operations.
Core Concepts

- Subnetting basics – Understanding divisions of networks
- Router & Switch functions
- Firewall purpose
Practical Skills
- File sharing between two systems
- Remote Desktop Connection (RDP)
- Connecting to VPNs
- Network troubleshooting (ping, tracert, ipconfig commands)
- Printer and device sharing
Why This Matters?
Even software developers require network understanding for debugging and testing. Support and IT operations roles rely heavily on basic networking skills.
5. Basic System and Web Security Concepts
Security awareness is no longer optional.
System Security Essentials

- OS updates and patching
Web Security Basics
- HTTPS vs HTTP
- SSL certificates and encryption
- Common vulnerabilities
- SQL Injection
- XSS (Cross-Site Scripting)
- CSRF
- Secure coding practices
- Using firewalls and WAF (Web Application Firewall)
