In the context of computers, communication overhead is those bits of data that must be sent to convey information about, for example, where the information originated and where it is being sent to, how it is to be routed, timestamps, or any other information that is not actually the "payload" representing the actual content to be communicated.
Communication overhead in wireless sensor networks (WSNs) refers to the additional resources and time required for transmitting data beyond the actual payload. This includes factors such as protocol headers, acknowledgments, retransmissions, and routing information that must be sent alongside the primary data to ensure successful delivery and network reliability. High communication overhead can lead to increased energy consumption, reduced network lifespan, and lower overall efficiency, making it crucial to optimize communication protocols in WSNs.

Overhead rate : Overhead rate = total overhead cost / direct labor OR Overhead rate = Total overhead cost / machine hours.
The speaker for the overhead serves as an audio output device that amplifies sound for larger audiences in settings like classrooms, auditoriums, or public events. It is typically used to project announcements, music, or presentations to ensure clarity and reach, enhancing communication and engagement. Additionally, overhead speakers often integrate with multimedia systems to provide an immersive experience during presentations or performances.
The adverb is overhead.
The two types of overhead are fixed overhead and variable overhead. Fixed overhead remains constant regardless of production levels, while variable overhead fluctuates in direct proportion to production activity.
Overhead can be an adverb. But it can also be an adjective or noun. Planes flying "overhead" would be an adverb. Overhead wires would be an adjective. The overhead of a business would be a noun.

To calculate under or overapplied overhead, subtract the actual overhead costs from the applied overhead costs. If the actual overhead costs exceed the applied overhead costs, it is overapplied. If the applied overhead costs exceed the actual overhead costs, it is underapplied.
Combined overhead variance = fixed overhead variance + variable overhead varianceFixed Overhead :which remains fixed and donot change upto certain level of productionVariable Overhead: which keep changing with the change in production units.
Using direct labor hours: Overhead rate = Total Overhead Expenses /Direct labor hours Using Machine hours: Overhead rate = Total Overhead Expenses /Machine hours
