Question

If a file consisting of $50,000$ characters takes $40$ seconds to send, then the data rate is _________

• A. $1$ kbps
• B. $1.25$ kbps
• C. $2$ kbps
• D. $10$ kbps

Comments

50000 characters = 400 000 bits in 40 sec so 400 000/40 =10 000 bps i.e 10 kbps

Answer 1

Since typically system takes 1 byte for one character.

So total byte of data=50000*1Byte=50,000Byte

Now it takes 40 sec to send 50,000 Byte

Bandwidth=how many bytes send in 1 sec.

50000/40=1250Byte/sec.

In bps=1250*8/sec=10kbps

Answer 2

Ans. -4) 10kbps

Answer 3

50,000 character takes 40 seconds 
ie 50,000 * 8 = 40 seconds. (each character is of 8 bits)
   In one second → (50,000 * 8)/40 bits / second.
  10,000  bits / second.
ie. 10 Kbps.

So, option (D) is correct.
