Answer:

82,944 = total possible ID's

Explanation:

In order to find the total number of combinations possible we need to multiply the possible choices of each value in the ID with the possible choices of the other values. Since the ID has 3 letters and 1 digit, and each letter has 24 possible choices while the digit has 6 possible values then we would need to make the following calculation...

24 * 24 * 24 * 6 = total possible ID's

82,944 = total possible ID's

Answer:

All the ports in a hub are in the same collision domain and a hub sends frames from one host to all other hosts in the network. This makes it prone to collision and poor network throughput. Just like a network switch, it uses the CSMA/CD protocol to detect collision in its network.

A network switch reduces its collision domain to just a port and sends frames from one host to another using its mac table as a route. This makes the network very efficient with high throughput. It also uses the CSMA/CD protocol to detect collision

Explanation:

Switches and hubs are used in networking to connect computer devices in a network. A hub is an obsolete device networking that broadcast a frame to all other ports or host in the network except for the send host port. This increases the rate of collision as all the ports in a hub share the same collision domain. A switch is an efficient frame switching device in a network, which uses its MAC table to decide and find a destination host.

CSMA/CD is a collision detection protocol used in a network to detect and prevent a collision. With this protocol, a host is able to listen, wait, send and resend frames to prevent a collision.

The thermal efficiency of a heat engine is defined as the net work output divided by the heat input.

A heat engine is a device that uses thermal energy from a heat source to convert some of that energy into useful work. Heat engines are typically used in power plants, automotive engines, and other mechanical devices. Heat engines work by transferring heat from a hotter area to a cooler area, and then using the resulting temperature difference to create mechanical work. Heat engines are based on the principles of thermodynamics, which involve transferring heat to create a pressure differential that can be used to generate power. Heat engines are typically classified as either external combustion or internal combustion, depending on where the heat is generated.

This is calculated by dividing the net work output (the total work output minus any losses) by the total heat input. This tells us how much useful work is produced compared to the total heat input.

Answer:

c. $620

Explanation:

To find the cost of the security deposit, we need to subtract the amount paid towards the first and last month's rent from the total move-in cost.

Each friend paid $640 towards the total move-in cost, which includes the first and last month's rent and the security deposit. Since they split the cost evenly, the total move-in cost is 3 times $640, which is $1920.

The monthly rent is $650 per month, so the first and last month's rent combined is 2 times $650, which is $1300.

To find the security deposit, we subtract the first and last month's rent from the total move-in cost:

Security deposit = Total move-in cost - First and last month's rent

Security deposit = $1920 - $1300

Security deposit = $620

Therefore, the security deposit was $620.

Option c. $620 is the correct answer.
