Which is an access method in which collision is entirely avoided?
Csma/cd
What is meant by private visibilty of a method?
It means that the method is visible from only within the current method. Also, any class that wants to use or invoke the private method has to create an object of the class in which the method is created in order to access/invoke it. The private access modifier is the most restrictive of the four java access modifiers. The total opposite of private is public which gives access to everyone.
It is perfectly legal to any instance variable inside of a static method?
No. You will get compilation errors. The complier will complain that you are trying to access non static variables from inside a static method. A static method can access only static variables.
Logical access control method can be used to limit access to specific resources in a domain environment?
Access control list (ACL)
Which of these is an access modifier for a method - void protected int or main?
* void - This is a return type - or, more correctly, specifies that a method has no return type.* protected - This is an access modifier. It says that the only classes that can call this method are subclasses and classes in the same package.* int - This is a value type (or return type).* main - This is the name of the method.

What is the access method for star topologies?
Most star topologies use CSMA/CD for a Local Area Network. WANs and MANs are different and use completely different access methods.
CSMA stands for?
carier sense multiple access
Explain the operation of CSMA-CD media access control method?
Collisions can decrease network performance.
Which are two characteristics for Ethernet standard?
