The four parts of body play important role in eliminating waste material from our body Lungs : remove carbon dioxide through exhalation Kidneys : filter waste and excess substances from the blood, producing urine Skin : removes waste through sweating Liver : detoxifies harmful substances and aids in their removal

Explanation
WinZip is a widely used data compression utility that allows users to compress files into smaller sizes for easier storage and sharing. It supports various formats like .zip and .rar for both compression and extraction of files.

Explanation
Offline synchronization allows data to be synchronized and accessed without an internet connection. It ensures the app works seamlessly by syncing changes once the internet is available.

Explanation
To get location in Android , you need to request the following permissions in your app's manifest:  ACCESS_COARSE_LOCATION : Allows the API to return an approximate location ACCESS_FINE_LOCATION : Allows the API to return a precise location ACCESS_BACKGROUND_LOCATION : Allows the app to access location in the background

Explanation
Services : Perform tasks in the background and continue running even if the user switches to another app. By default, they run on the main thread. Threads : Operate within the app's lifecycle, are used for parallel execution, and stop when the app stops.

Explanation
Each Android application lives in a security sandbox . It ensuring isolation from other apps for data and security protection . This sandbox prevents unauthorized access to the app's files and resources.

Explanation
2.5G systems are typically characterized by very small cells, especially in densely populated areas. This allows for efficient frequency reuse and improved network capacity .

Explanation
The basic GSM is based on Connection oriented traffic channels. It ensuring a dedicated connection during communication. This approach guarantees continuous data transmission between users.

Explanation
In FDMA , the frequency spectrum is divided into smaller spectra, with each user allocated a specific frequency band. This ensures simultaneous communication by separating users via distinct frequency channels.

Explanation
Fading occurs due to Multipath propagation , where signals take multiple paths to reach the receiver, causing interference. This is a common phenomenon in mobile communication environments.

Explanation
To adjust a column width to fit its contents in Excel, you can: Double-click the boundary to the right of the column heading. This action automatically resizes the column width to match the longest entry in that column. This ensuring that all data is visible without manually adjusting the width.
