Answer:

Radius = 14 cm = 0.00014 km

Circumference = 2πr = 2 × 22/7 × 14/100000 = 0.00088 km

As it went thousand times , distance covered = 0.00088 × 1000 = 0.88 km

B. Malware

Explanation:

Malware is general to most harmful programs on a computer, as Adware is a potentially unwanted program that is designed to advertise other programs or services. And ransomware is a program that will encrypt important user files such as; documents, pictures, and videos. Spyware is a program that is designed to spy on users, examples are; using your camera without your consent, key-loggers, and taking screenshots of our desktop. Thus i believe it is malware because the question covers multiple categories.

4. In this problem, we consider sending real-time voice from Host A to Host B over a packet-switchednetwork (VoIP). Host A conve
mina [271]

Answer:

The time elapsed is 0.017224 s

Solution:

As per the question:

Analog signal to digital bit stream conversion by Host A =64 kbps

Byte packets obtained by Host A = 56 bytes

Rate of transmission = 2 Mbps

Propagation delay = 10 ms = 0.01 s

Now,

Considering the packets' first bit, as its transmission is only after the generation of all the bits in the packet.

Time taken to generate and convert all the bits into digital signal is given by;

t = \frac{Total\ No.\ of\ packets}{A/D\ bit\ stream\ conversion}

t = \frac{56\times 8}{64\times 10^{3}}          (Since, 1 byte = 8 bits)

t = 7 ms = 0.007 s

Time Required for transmission of the packet, t':

t' = \frac{Total\ No.\ of\ packets}{Transmission\ rate}

t' = \frac{56\times 8}{2\times 10^{6}} = 2.24\times 10^{- 4} s

Now, the time elapse between the bit creation and its decoding is given by:

t + t'  + propagation delay= 0.007 + 2.24\times 10^{- 4} s + 0.01= 0.017224 s
