Compare and contast controlled media access and contention-based media access control?
Controlled-based media access control is based upon having a system in place for allowing one host to transmit at a time. It is also known as deterministic method since there is a process to determine which host transmits at a certain time. No collisions exist with this type of media access control. An example would be token ring where a token is passed from host to host and when it has the token it can transmit and others do not transmit at that time. Contention-based media access control is known as non-deterministic because hosts can transmit whenever they want. CSMA/CD is an example of this. Collisions do exist.
Why collision is an issue in a random access protocol?
In random access methods, there is no access control (as there is in controlled access methods) and there is no predefined channels (as in channelization). Each station can transmit when it desires. This liberty may create collision.
Where does wireless transmit and receive signal from?
It has an access point which transmit signal to the client and receive.
What are contention based MAC?
Contention-based Medium Access Control (MAC) protocols are networking protocols that allow multiple devices to compete for access to a shared communication medium. In these protocols, devices transmit data whenever the medium is idle, leading to potential collisions if multiple devices transmit simultaneously. Common examples include Carrier Sense Multiple Access (CSMA) and its variations, such as CSMA/CD (Collision Detection) and CSMA/CA (Collision Avoidance). These protocols are widely used in wireless and wired networks to manage how devices communicate and share bandwidth efficiently.
What is an internal control practice to access whether commitments and obligations are bona fide needs of the appropriations charged?
TAR
What Settings category allows you to control whether apps can access your location Question 2 options?
The Settings category that allows you to control whether apps can access your location is typically labeled "Privacy" or "Location Services." Within this section, you can manage location access for individual apps, allowing you to enable or disable their ability to use your device's location. This helps ensure your privacy and control over location data sharing.

What type of access control is determined by configuring an access control list or ACL?
Discretionary Access Control
Difference between media access control and LLC?
* MAC sublayer(802.3): defines how to transmit data on physical layer * LLC sublayer(802.2): responsible for identifying different protocol logically & encapsulate them.
What is a software control?
"Access control" means that you control who has access to certain things - so an access control software is software that helps you achieve that.
How can you control the access to a system?
You can control the access to a system by buying or downloading certain programs. An example of a program that gives you the ability to control the access to a system is Network Access Control.
