Answer:
MAC Addresses (Destination and Source MAC address)
Explanation:
A switch has 3 primary functions:
- Forward frames
- Learn addresses
- Avoid loops
An Ethernet frame has the header, data and trailer and there are two specific fields in the header that helps the switch to know where to send data in future transmissions.
- destination MAC address
- source MAC address
every Ethernet frame has this and when the frame hits a switch or any device, any device can look at it ( an Ethernet frame ) and know where it is suppose to go and where it came from.
Every switch has a MAC address table where it stores MAC addresses of different computers on the network.
Example:
When a PC1 sends a frame to PC2 through a switch, the switch looks at the header of the Ethernet frame for the source mac address and adds the source MAC address to its MAC address table and also the port that it came through.
simply put:
A switch looks at the source MAC address to see if it knows it already, if it does. Great! no need to add it again to it's address table.
If it doesn't, it adds it's source address and the port that the frame came from.
This basically how the switch populates its MAC address table.
Answer:Analog component signals are comprised of three signals, analog R′G′B′ or YPbPr. Referred to as 480i (since there are typically 480 active scan lines per frame and they are interlaced), the frame rate is usually 29.97 Hz (30/1.001) for compatibility with (M) NTSC timing.
Explanation:
Answer:
Following are the program definition in the Java Programming Language.
//define a class
public class Clock
{
//set integer type variable and initialize value
private int hours=12;
//set boolean type variable and initialize value
private boolean isTicking=true;
//set integer type variable and initialize value
private Integer diff=5;
}
Explanation:
Following are the description of Code.
- Firstly define a class "Clock" with the "private" access modifier.
- Then, set the integer data type variable "hours" with the "private" access modifier and assign value 12 in that class.
- After that, set the boolean data type variable "isTicking" with the "private" access modifier and assign value "true".
- Finally set Integer class variable "diff" with the the private access modifier and assign value 5.

Answer:
LEDs are powered by alternating current AC.
Explanation:
The electricity will move in and out of cycles.
When the FPS won't math it'll flicker. Try switching to your camera's shutter speed instead. ( May be times your camera won't support it.)
