What is Overhead?
Overhead refers to the extra processing or additional load that occurs when a computer performs a task.
In Simple Terms
Overhead is the extra work or burden that occurs alongside the main task a computer is trying to accomplish.
Detailed Explanation
- Additional Processing
- For instance, when a computer reads data, it might need to convert the data into a different format. This conversion process is overhead because it is not directly related to reading the data but is necessary to complete the task.
- Load
- This extra work increases the burden on the computer, which can slow down the system or consume additional resources. This is also considered overhead.
- Example
- Consider ordering a pizza. The time and cost associated with delivery are overhead. The pizza itself is the main goal, but the extra time and cost for delivery are overhead.
- Improvement
- Reducing overhead means making the main task more efficient. For example, if you prepare ingredients in advance, you can cook faster, just as reducing overhead in a computer task can make processes run more smoothly.
Summary
“Overhead” refers to the extra processing or load that occurs alongside the main task being performed by a computer.
