Which statement describes one of the responsibilities of a computer programmer?

Given a typical magnetic hard drive with five platters, answer the following:

Nataly_w [17]

Answer:

Given the number of platters =5

A. Hence, the number of recording surface =10

B. number of read-write heads =10

C. Number of arms holding the read-write heads = 10

Explanation:

We know that number of recording surface = 2 *( number of platters)

= 2*5=10

And the number of read-write heads = number of recording surface= 10

Also, number of arms holding the read-write head = one for each read-write head= 10

And hence, the above answer.

To what would you compare the transport layer?

GarryVolchara [31]

The above question has multiple choices as below

<span>A. Data links
B. The post office
C. Driving a car
D. A train

The answer is (B) The Post Office.

In layman’s terms, transport layer is similar to the post office functions of delivering parcels and letters at the agreed delivery deadlines. It also notices any dropped info and re-transmits it.
Just like the post office, the transport layer directs messages and information between specific end users. If by mistake you write a letter to the wrong person, the letter will be returned and the postal employee will stamp it as address unknown.

) how many bits are used for host number on the child network (subnet) , b) how many usable addresses can exist on this child ne

vovikov84 [41]

Answer:

Machine’s IP=126.127.85.170, Machine’s Netmask=/27, Parent’s Netmask=255.255.240.0 .

a) Machine's Netmask = /27 : therefore no. of remaining bits for hosts =32-27 = 5 bits.

b) No. of usable addresses in the child network = 25 -2 = 32-2 =30 [Since first(network ID of the machine) and last ip (broadcast address of the machine ) addresses are not used ]

c) first usable address is on this child network (subnet) =

First, find out the network id of machine can be found out by doing bitwise AND machine's IP and Machine's subnet mask :

01111110. 01111111.01010101.10101010 (IP)

11111111. 11111111 .11111111 .11100000 (Subnet Mask)

01111110. 01111111. 01010101.10100000 (Network ID )

first usable address is on this child network (subnet) : 01111110. 01111111. 01010101.10100001

: 126.127.85.161

d) what the last usable address is on this child network (subnet) : 01111110. 01111111. 01010101.10111110

: 126.127.85.190

e) what the child network’s (subnet's) broadcast address is :

In the directed broadcast address , all the host bits are 1. Therefore, broadcast address :

01111110. 01111111. 01010101.10111111 (126.127.85.191)

f) what the child network's (subnet's) network number is : Network ID has already been calcuulated in part c .

01111110. 01111111. 01010101.10100000 (126.127.85.160)
