A session, in simple terms, refers to the period during which a user is actively engaged with a website, application, or system. Starting when a user logs in or accesses the system, it ends when the user logs out, after a period of inactivity, or when the system is shut down. The session tracks the user’s activity and stores information needed for interaction. This can include user preferences, authentication details, and more. It’s much like an ongoing conversation between the user and the system.
Session Examples
#1. Online Shopping
Consider a situation where you’re shopping on your favorite online store. You browse through various categories, pick out a few items you like, and add them to your shopping cart. But maybe you’re unsure about a product, you want to compare prices, or you simply get distracted, so you navigate away from the page without checking out.
Stay One Step Ahead of Cyber Threats
When you return to the site later, maybe even from a different device, your items are still there in your cart. This is made possible by a session. The session begins when you first visit the site and continues to track your activity even as you browse other pages. It remembers the items you’ve added to your shopping cart until you decide to either complete your purchase or remove the items. This convenience and consistency in user experience is one of the advantages provided by sessions.
#2. Email Account Activity
When you log into your email account, such as Gmail or Yahoo, a session is initiated. This session allows you to interact with the platform, opening the door to various email management tasks. For instance, you can read your new emails, send a quick message to a friend, delete spam, or move some emails into specific folders. Each of these activities is part of your session.
The moment you decide to log out of your email account, the active session concludes. In most cases, your email provider safeguards your privacy by automatically ending your session after a period of inactivity. This is especially handy if you forget to log out after checking your email in a public space like a library or internet cafe. The session not only helps organize and streamline your activities but also plays a vital role in maintaining the security and privacy of your digital communications.
#3. Online Banking
Consider the situation when you access your bank account online. The moment you enter your login credentials and gain access to your account, a session starts. This session allows you to interact with the banking platform. You can check your balance, view your statement, transfer funds, or pay bills. Each activity within the banking platform is part of your session.
Security is key in online banking. If you become inactive on the site or simply leave the site without logging out, the bank will typically end your session after a specific period. If you want to return to your account activities, you will be prompted to log in again to start a new session. By automatically ending sessions after periods of inactivity, the bank can significantly reduce the risk of unauthorized access and potential fraudulent activities, providing you with a secure online banking experience.
Conclusion
In the digital world, sessions play a crucial role in enhancing user experience and maintaining security across various platforms. Be it online shopping, email activities, or online banking, sessions ensure consistency in user interactions, and enable protection of user data by tracking activity and ending sessions to prevent unauthorized access.
