Answer:

beacon frame  

Explanation:

Beacon frame is a management frame In computer networks, known to be in IEEE 802.11 based WLANs. These frames are transmitted periodically and they contain all the  information a station will require before it can rightly transmit a frame.  

When it comes to announcing the presence of devices in a wireless computer network (WLAN), Beacon frames are used, and they can also be used in the synchronization of the devices and services

In 4-bit two's complement representation, what is the binary encoding of the number -5?
Katena32 [7]

Answer:

a) 1011

Explanation:

In 4 bit two's complement representation, the first bit is the sign bit.

If the sign bit is 1, the number is negative.

If the sign bit is 0, the number is positive.

What is the magnitude of the sign bit?

In n-bit two's complement representation, the magnitude of the sign bit is:

2^{n-1}-1

So, in 4-bit two's complement representation, the magnitude of the sign bit is:

2^{4-1}-1 = 8

Since the number is negative, the value of this bit is -8.

The other bits are magnitude bits, positive.

We have that the sum of these bits must be -5, and we already have -8. So what should be the value of these last 3 bits?

First, i am going to solve this equation to find the decimal value of the last three bits.

-5 = -8 + x

x = 3

So, the last three bits are:

3_{10} = (011)_{2}

The binary encoding of the number -5 is:

a) 1011
