Answer:
public static void drawGraphics (Graphics g, int width, int height) {
int r = Math.round(width/2);
int x = 45;
int y = 30;
g.setColor(Color.RED);
g.fillRect(x, y, width, height);
g.setColor(Color.BLUE);
g.fillOval(Math.round(x/2), Math.round(y/2), r, r);
}
Explanation:
The Java method "drawGraphics" of the Graphics class accepts draws a square with the "fillRect()" method of the Graphics class object and at its center, a circular path is drawn as well.
Answer:
Nodes
Explanation
All of the computers and printers on the network are called nodes of the network
Wireless networks experience such a great reduction in actual throughput compared with their respective theoretical throughputs, because wireless networks experience a high number of collisions and require greater overhead on each transmission. The throughput varies significantly from the theoretical maximum speeds due to:
distance from the access point, physical obstructions, such as walls, signal-blocking or reflecting materials which affect signal propagation and reduce speed
, interference - other wireless networks and devices in the same frequency in the same area affect performance
and shared bandwidth - available bandwidth is shared between all users on the same wireless network.

Answer:
DNS poisoning
Explanation:
DNS is a server service that verifies or resolves an IP address to a site or domain name. It's services is made available with a dhcp request from a client system, providing the ip address of the DNS server. The DNS server has the records of domain name linked to their individual ip addresses.
When an attacker wants a client to visit his site without knowing the site is not genuine, he gains access to the dns server and changes the information or poisons the entries of the server. So if the client tries to access that site, it takes him to the attackers site. This is called DNS poisoning.
