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

Why is the keyboard calledQWERTY
taurus [48]
The standard QWERTY layout keyboard is called 'QWERTY' because on the top line of the keyboard the first 6 letters from chronological left to right order are; Q, W, E, R, T, and Y.

Or...if you're wondering why it's QWERTY and not ABCDEF, it's because when typing with the alphabetical format, many of the keys would clash with each other due to the arrangement of keys on the original typewriter. The QWERTY layout became so popular, it was the standardized layout for typewriters, and even keyboards today.

Drupady [299]

The keyboard combinations that can be used to capture and print out a one-slide presentation using MSWord, showing everything on the screen is Function key + PrtScr

<h3>What is a Key Combination?</h3>

This refers to the procedure that is used to combine two or more keys on the keyboard to execute a task.

Hence, we can see that the procedure that can be used to carry out the operation is:

  • Enter the screen you want to capture and print
  • Press the Function key, followed by the PrtScr. Please note this can vary slightly, depending on the keyboard.

The hardware devices that would be needed to be set up by the system analyst at a computer laboratory are:

  • System Unit
  • Laptops/Monitor
  • Power adapters
  • Ethernet cables, etc

The database applications that can be recommended by the system analyst are:

  • MySQL,
  • SQL Server

The five word processing packages that are likely to be installed are:

jeyben [28]

Answer:

B. Assign roles and privileges to users so that only job-relevant data is accessible to the user.

Explanation:

Certain departments will require certain information for certain processes. It is not recommendable for every user to access every information of the company as it may reveal vital information.

Hence, every role and department should be given certain privileges to information according to the tasks and needs of the role.
