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 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.
What is a access control software?
Access control software refers to systems that manage and regulate entry to physical or virtual spaces, often using authentication mechanisms like passwords, biometrics, or access cards. While it's true that access control software enhances security by limiting unauthorized access, it's crucial to acknowledge potential drawbacks. Overreliance on such software can create a false sense of security, overlooking vulnerabilities like social engineering or insider threats. Additionally, excessive reliance on access control may impede user convenience and hinder productivity. Therefore, while access control software serves a purpose, it's imperative to adopt a holistic security approach that addresses diverse threats and balances security with usability.
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.
How to use the NFC function of a smart watch to set up an access control card?
While using NFC on a smartwatch for access control sounds convenient, it raises security concerns. Smartwatches lack the robust security features of dedicated access control systems, making them vulnerable to hacking and cloning. Relying on such technology compromises the integrity of access control, potentially endangering sensitive areas. It's essential to prioritize security over convenience in access control systems to prevent unauthorized access and ensure the safety of individuals and assets. Instead, investing in established access control methods with stringent security measures is imperative for safeguarding against potential breaches.
