Answer:
is a generic description for how computers use multiple layers of protocol rules to communicate across a network.
Explanation:
OSI model stands for Open Systems Interconnection. The seven layers of OSI model architecture starts from the Hardware Layers (Layers in Hardware Systems) to Software Layers (Layers in Software Systems) and includes the following;
1. Physical Layer.
2. Data link Layer.
3. Network Layer.
4. Transport Layer.
5. Session Layer.
6. Presentation Layer.
7. Application Layer.
Hence, the Open Systems Interconnection (OSI) Reference Model is a generic description for how computers use multiple layers of protocol rules to communicate across a network.
Additionally, each layer has its unique functionality which is responsible for the proper functioning of the communication services.

300 + 335 = 635
Answer:
The correct answer to the following question will be "DHCP server".
Explanation:
A network manager that dynamically supplies and delegates equipment of clients with their IP addresses, standard portals and some other networking specifications, known as DHCP server.
- It depends on the standard operating procedure classified as Dynamic Host Configuration Protocol to answer to client-specific broadcasting commands.
- It's used to optimize the authentication mechanism of computers on IP channels, enabling them using applications and services including NTP, DNS, and any UDP or TCP-based networking protocol.
Therefore, the DHCP server is the right answer.
Answer:
2. <em>A reference of type A can be treated as a reference of type B</em> - False
Base class or its objects are not related to their derived class (or its objects).
Explanation:
class A {
int a;
public A() {
a = 7;
}
}
class B extends A {
int b;
public B() {
b = 8;
}
}
///////////////////////////////////////////////////////////////////////////////////////////////////////
1. <em>After the constructor for class B executes, the variable a will have the value 7 </em>- True.
When an object of a derived class is declared, the constructor of base class is called before the constructor of derived class (is called).
3. <em>Both variables a and b are instance variables </em>- True.
Classes can have instance, or member, variables and methods.
4.<em> After the constructor for class B executes, the variable b will have the value 8</em> - True.
When object of class B is declared, its constructor was called, which initialized variable b to 8.
