Answer:
<u>The total time elapsed from the time a bit is created (from the original analog signal at Host A) until the bit is decoded (as part of the analog signal at Host B is </u><u>25.11 ms</u>
Explanation:
Host A first converts the analog signal to a digital 64kbps stream and then groups it into 56-byte packets. The time taken for this can be calculated as:
time taken 1= 
= (56 x 8) bits / 64 x 10³ bits/s
= 7 x 10⁻³s
time taken 1= 7 ms
The transmission rate of the packet from Host A to Host B is 4 Mbps. The time taken to transfer the packets can be calculated as:
time taken 2= (56 x 8) bits / 4 x 10⁶ bits/s
= 1.12 x 10⁻⁴ s
time taken 2= 112 μs
The propagation delay is 18 ms.
To calculate the total time elapsed, we need to add up all the time taken at each individual stage.
<u />
<u> = Time taken 1 + Time taken 2 + Propagation Delay</u>
= 7 ms + 112 μs + 18 ms
= 0.025112 s
= 25.11 ms
Answer:
The answer is "check the worksheet is not read only"
Explanation:
The read only mode is used for read the file data, and it doesn't allows the user to update the file, and for updating the worksheet we should check iut does not open in the read-only mode.
If it is open, then we close it and for close we goto the office button and click on the tools option after that goto general setting, in this there is a check box for turn off the read-only mode.
Answer:
The data can be safeguarded using key escrow procedure.
Explanation:
Key escrow basically means to store the cryptographic key in an "escrow" by a reputable trusted third party. The copy of the encryption key is kept with the third party. In case the cryptographic key gets lost or destroyed, then the key escrow service helps to access the encrypted data. It also manages the access control to the key in case the key gets lost. So this way in case of security breach at GearOn the key escrow service can be used to re-implement or access the key easily.
Answer:
x=2
x=1
x=2
Explanation:
a)
This if statement if (1+2=3) checks if the addition of two numbers 1 and 2 is true. Here the addition of 1 and 2 is 3 which is true. So the condition becomes true.
Since the condition is true x:=x+1 statement is executed. This statement means that the value of x is incremented by 1.
The value of x was 1 before the if statement is reached. So x:=x+1 statement will add 1 to that value of x.
x:=x+1 means x=x+1 which is x=1+1 So x=2
Hence value of x is 2 (x=2) after the execution of x:=x+1
b)
In statement b the value of x will be 1 because both the mathematical operations in the if statement evaluate to false.
which means in b, x:=x+1 will not be executed and value of x remains unchanged i.e x=1
In (c) the value x will be 2 because the condition in the if statement is true. Both mathematical expressions 2+3=5 and 3+4=7 are true. Therefore x:=x+1 will be executed and value of x will be incremented by 1. Hence x=2
The separate identity allows the database definition to be changed without affecting related applications is known as <u>DATA.</u>
<u>Explanation:</u>
Normally nowadays program and database are keeping separately. MySQL server, mongo dB, oracle, sql server extra installed separate followed folder or separate drive in operating system.
So software program just use connectivity technology to add or update or delete information from in the database. Form or report just access the data from database and produce required output.
Normal SQL database will stored as records as rows in tables. Normally database can been access through database application directly to update records such as SQL PLUS, MYSQL workbench etc.
