) 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)

An operating system is defined as hardware that converts software into a useful form for applications.

marissa [1.9K]

Hardware that transforms software into a form that is helpful for applications is referred to as an operating system. False. Hardware conversion is done by software.

<h3>What is an operating system?</h3>

Computer hardware and software resources are managed by an operating system (OS), which also offers common functions for software programs.
Operating systems that use time-sharing plan activities to make the most of the system's resources.
They may also contain accounting software to allocate costs for processing time, mass storage, printing, and other resources.
An operating system (OS) is a piece of software that controls all of the other application programs in a computer after being originally loaded by a boot program.
Through a specified application program interface, the application programs seek services from the operating system (API).
