A broadcast network is one in which a transmission from any one attached station is received by all other attached stations over a shared medium. examples are a bustopology local area network, such as ethernet, and a wireless radio network. discuss the need or lack of need for a network layer (osi layer 3) in a broadcast network

Answers

Answer 1

Broadcast frames are layer 2 and not Layer 3, examples are DHCP/ARP/RARP etc. request. A Router will block all broadcast traffic unless configured to let the specific packet through via the IP Helper statement to direct to a remote DHCP server and back.
Obviously, a bus topology this is OLD technology they rarely exist anymore. Today, switches have taken over the dumb hubs or even vampire taps on a coax cable. However, a broadcast it still passed on to every port on the switch, unless configured not to do so. Anyway, I could go on and on.

Explanation:

The truth is, hiring a professional web designer or design firm is not for everyone.

If you’re a new business without much revenue, then using an affordable website builder is exactly what you should be doing.

However, if you own a small or medium sized business, using a ‘free’ website builder could cost your company many tens of thousands of dollars in wasted man hours and even more money in the opportunity cost of lost potential revenue.

In this article, we will address several aspects of the debate, “web designer vs website builder?” Who would be better off hiring a professional and the specific advantages and disadvantages of doing either?

Class sizes of various sections of college algebra at your university are an example of which type of data? quiizlet

Answers

Final answer:

Class sizes of various sections of college algebra at your university are an example of quantitative data, specifically discrete quantitative data.

Explanation:

The class sizes of various sections of college algebra at your university are an example of quantitative data. Quantitative data represents numerical values that can be measured or counted.

Specifically, the class sizes can be represented as discrete quantitative data, as the number of students in each section is a whole number value. For example, one section may have 30 students, another section may have 25 students, and so on.

Look at the simple circuit illustrated in the figure above. What will happen when only switch S1 is closed?

A. No current will flow in the circuit.
B. Nothing will happen; the light bulb won't light up.
C. The light bulb will light up.
D. The resistance of the circuit will increase.

Answers

If only S1 is closed, due to the diode across S3 is pointing to the right, the current cannot be flowing to the left.

So nothing will happen, the bulb is not on.

Answer: A. No current will flow in the circuit.

Explanation:

The Figure 1 illustrates the equivalent circuit at only switch S1 closed. That is a series circuit with two diodes, a bulb, and a battery.

Suppose that there is a current flowing in the circuit. A current flowing in the circuit implies that D1 is on. If D1 is on, there should be 0.7 V between anode and cathode (see Figure 2 left). However, there is not possible a low voltage on the top and a high voltage at the bottom of D1 (see Figure 2 right). Then, it is not viable 0.7 V between anode and cathode of diode D1. Therefore, D1 is off.

Now, we already know that this is a series circuit with the diode D1 off, so we can conclude that no current will flow in the circuit.

Correct answer is A. No current will flow in the circuit.

There isn't current flowing in the circuit next the light bulb won't light up. But other things happen, for example, the high voltage goes to the light bulb at only switch S1 closed. we can say that option B. is partially wrong and options C. is wrong

Finally, there are no resistances in the circuit. So, option D. is not right

Open the hood.
Use a rag or gloves to protect your hands from the heat.
Slowly very slowly with the gloves on after you have let the vehicle cool down a bit.
Open the radiator check if you have coolant in it.
If you don't you will need to refill it with the same coolant you use last time.
If you can't get coolant you can use water to get your car to a shop or home.
Using water can freeze when the temperature gets to low in winter
When water freezes it expands and will crack parts and can cause a lot of damage.
When you get your car to the shop or home flush out the radiator and fill it up with new coolant or antifreeze
Coolant or antifreeze sometimes come as a concentrate so you may mix it with water some you don't mix read the directions before you start.

A computer has a word length of 8 bits (including sign). if 2’s complement is used to represent negative numbers, what range of integers can be stored in the computer? if 1’s complement is used? (express your answers in decimal.)

Answers

Two's-complement notation can represent all integers from - 2^(N-1) to 2^(N-1) - 1, where N is the word length of the computer. So, in your example, the computer could store all integers from -128 to 127 inclusive.

One's-complement notation can represent all integers from - 2^(N-1) - 1 to 2^(N-1) - 1, where N is the word length of the computer. So, in your example, the computer could store all integers from -127 to 127 inclusive

The word length of a computer is simply the number of bits, the computer can process

The word length is given as:

[tex]n = 8[/tex]

(a) 2's complements

The smallest integer in the 2's complement is::

[tex]N= -(2^{n-1})[/tex]

While the largest integer is:

[tex]N= 2^{n-1} -1[/tex]

So, we have:

[tex]Smallest = -(2^{8-1})[/tex]

[tex]Smallest = -(2^7})[/tex]

[tex]Smallest = -128[/tex]

And the largest is:

[tex]Largest= 2^{8-1}-1[/tex]

[tex]Largest= 2^{7}-1[/tex]

[tex]Largest= 128-1[/tex]

[tex]Largest= 127[/tex]

Hence, the computer can store all integers from within an inclusive range of -128 to 127, using the 2's complement

(b) 1's complements

The smallest integer in the 1's complement is::

[tex]N= -(2^{n-1}) + 1[/tex]

While the largest integer is:

[tex]N= 2^{n-1} -1[/tex]

So, we have:

[tex]Smallest = -(2^{8-1})+1[/tex]

[tex]Smallest = -(2^7})+1[/tex]

[tex]Smallest = -128+1[/tex]

[tex]Smallest = -127[/tex]

And the largest is:

[tex]Largest= 2^{8-1}-1[/tex]

[tex]Largest= 2^{7}-1[/tex]

[tex]Largest= 128-1[/tex]

[tex]Largest= 127[/tex]

Hence, the computer can store all integers from within an inclusive range of -127 to 127, using the 1's complement
