Answer:
Number of packets ≈ 5339
Explanation:
let
X = no of packets that is not erased.
P ( each packet getting erased ) = 0.8
P ( each packet not getting erased ) = 0.2
P ( X ≥ 1000 ) = 0.99
E(x) = n * 0.2
var ( x ) = n * 0.2 * 0.8
∴ Z = X - ( n * 0.2 ) / 
~ N ( 0.1 )
attached below is the remaining part of the solution
note : For the value of <em>n</em> take the positive number
Correct answer: Neither
The CPU<span> is also known as the </span>processor<span> or microprocessor. The </span>CPU<span> is responsible for executing a sequence of stored instructions called a program. This program will take </span>inputs<span> from an </span>input<span> device, process the </span>input<span> in some way and </span>output<span> the results to an </span>output<span> device.</span> It is neither an input nor an output device, but it is usually connected to both kinds of devices.
Output devices like your monitor, speaker, and printer does not process anything fo it to be categorized as a processing device like your CPU and so as input devices like your mouse, microphone, and keyboard.
Answer:
A Tape Library
Explanation:
A tape library, sometimes called a tape silo, tape robot or tape jukebox, is a storage device that contains one or more tape drives, a number of slots to hold tape cartridges, a barcode reader to identify tape cartridges and an automated method for loading tapes. It Enables faster data migrations, reduce the complexity of and increase the frequency of backups, and streamline governance in a secure and cost-effective way.
In general, synchronous communication means you have to wait for the answer all the time. The programming logic is simpler, but the cost that you spend a lot of time waiting.
If the options are:
<span>a. The people communicating don't need to be online at the same time.
b. There is lag time in the communication.
c. The communication occurs in real time.
a is false, you do need to be online to receive the message
b is true, typically you continue only after an acknowledgement
c is true, you wait for acknowledgement that occurs in real time (not necessarily fast though)</span>
