Answer:
360 msec
Explanation:
Data provided in the question:
Distance between the two hosts = 15,000 kilometer
= 1.5 × 10⁷ m [ ∵ 1 km = 1000 m ]
Transmission rate, R = 5 Mbps = 5 × 10⁶ bits per second
Propagation speed over the link = 2.5 × 10⁸ meters/sec
Size of file to be sent = 1,500,000 bit
Now,
Propagation delay (dprop)
= Distance ÷ Speed
= ( 1.5 × 10⁷ ) ÷ (2.5 × 10⁸)
= 0.06 sec
= 60 msec [ ∵ 1 sec = 1000 millisecond ]
Transmission delay (dtrans)
= Size of file ÷ Rate of transmission
= 1500000 ÷ ( 5 × 10⁶ )
= 0.3 sec
= 300 msec
Therefore,
Time required for transmitting the file
= Propagation delay + Transmission delay
= 60 msec + 300 msec
= 360 msec
Answer and Explanation:
Using Javascript programming language, to write this script we define a function that checks for empty variables with if...else statements and then uses a for loop to loop through all arguments passed to the function's parameters and print them out to the console.
function Check_Arguments(a,b,c){
var ourArguments= [];
if(a){
ourArguments.push(a);}
else( console.log("no argument for a"); )
if(b){
ourArguments.push(b);}
else( console.log("no argument for b"); )
if(c){
ourArguments.push(c);}
else( console.log("no argument for c"); )
for(var i=0; i<ourArguments.length; i++){
Console.log(ourArguments[i]);
}
}
Answer
Software as a service
Explanation
Software as a service (SAAS) is a software distribution model in which a third-party provider hosts applications and makes them available to customers over the Internet. SAAS is one of three main categories of cloud computing.
Cloud computing is the use of internet to access hardware and software service instead of keeping regular physical hardware and software in the office space. Basically it is the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.
Answer:
This is because, the advertisers report the storage space in decimal while the computer reads the storage space in binary.
Explanation:
The advertisers report the storage space in decimal or base 10 because humans count in decimal, whereas the computer reports the storage space in binary or base 2.
Since the computer storage is in bytes and 8 bits equal 1 byte, It is easier to write a storage space of 1 kB as 1000 B but it is actually supposed to be 1024 B(2¹⁰). So, there is a discrepancy of 1024 B - 1000 B = 24 B.
As we go higher, the discrepancy increases. For example, 1 MB is advertised as 1000 kB = 1000000 B but is actually supposed to be 1024 kB = 1024 × 1024 B = 1048576 B. So, there is a discrepancy of 1048576 B - 1000000 B = 48576 B.
So, the actual number of bytes on the storage device is actually less than that reported due to the different number systems in which they are reported in. This discrepancy is less in memory cards or flash drives though in which the stated value of storage capacity might be the actual storage size.
Note that the base 10 or decimal system was chosen by advertiser since this is what consumers understand.
