Problem 61E
Data are transmitted over a particular Ethernet network in blocks of 1500 octets (blocks of 8 bits). How many blocks are required to transmit the following amounts of data over this Ethernet network? (Note that a byte is a synonym for an octet, a kilobyte is 1000 bytes, and a megabyte is 1,000.000 bytes.)
a) 150 kilobytes of data
b) 384 kilobytes of data
c) 1.544 megabytes of data
d) 45.3 megabytes of data

Problem 61E
Data are transmitted over a particular Ethernet network in blocks of 1500 octets (blocks of 8 bits). How many blocks are required to transmit the following amounts of data over this Ethernet network? (Note that a byte is a synonym for an octet, a kilobyte is 1000 bytes, and a megabyte is 1,000.000 bytes.)
a) 150 kilobytes of data
b) 384 kilobytes of data
c) 1.544 megabytes of data
d) 45.3 megabytes of data
ANSWER:
Solution:
Step 1:
In this problem we have to find the number of blocks are required to transmit over a particular Ethernet network in blocks of 1500 octets.
a: we have to find number of blocks are transmitted over a particular Ethernet network at 150 kilobytes of data.
Now blocks transmitting 150 kilobytes of data
= 150 1000
=150000 bytes (since 1 kilobytes = 1000 bytes)
= 150000= 1200000 bits
We given data are transmitted a particular Ethernet network in blocks of 1500 octets, which means that it is
= 1500 bytes
=1500 8 = 12000 bits
So, the number of blocks that can be transmitted
= []
= 100.
