The answer is column F. During relative copy and paste in Excel, the positioning of the '$' symbol effectively indicated an absolute reference to a position, so that is not updated. Therefore, in the formula '<span>=F$5+12</span>', only column F is updated.
The model is Parallel Distributed Processing Model (PDP) wherein m<span>Memory results from weblike connections among interacting processing units operating simultaneously, rather than sequentially ( also known as the connectionist model).</span>
Answer:
All of the above.
Explanation:
Thrashing or drive or disk thrashing occurs when the hard drive is stressed with transferring information between the system memory and virtual machine excessively. In thrashing, there is a large number of processes running in the system and the system memory is too small to handle all processes. Thrashing leads to decreased system performance and hard disk failure.
To stop the impact of thrashing, install more RAM, end unimportant progam processes etc.
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:
It is any information that is audio or video but not text.
