A host is on the 192.168.146.0 network that has a subnet mask of 255.255.255.0. The binary value of the host portion is 11010101
QveST [7]

Answer:

213

Explanation:

The given parameters are;

The network on which the host is on = 192.168.146.0

The subnet mast = 255.255.255.0

The binary value of the host portion = 11010101

To convert the binary value to decimal value, we proceed by multiplying each of the digits of the binary value by the corresponding power of 2, from the left to right, starting from a power of 0, and sum the result, as follows;

(11010101)₂ = (1×2⁷ + 1×2⁶ + 0×2⁵ + 1×2⁴ + 0×2³ + 1×2² + 0×2¹ + 1×2⁰)₁₀

1×2⁷+1×2⁶+0×2⁵+1×2⁴+0×2³+1×2²+0×2¹+1×2⁰= 128+64+0+16+4+1 = 213

∴ (11010101)₂ = (213)₁₀

The decimal value of 11010101 is 213.

How is the Microsoft Word 2013 window organized?
Alenkasestr [34]
The answer is (A): with contextual tabs for major groupings of editing features and ribbons with specific groupings to organize commands.


Contextual tab or tabs are hidden menu that appears when objects like images or texts are selected in programs like MS Word 2013. They typically contain one or more commands applicable to a selected text or object only. They are there in the Ribbon when you need them and disappear when you do not need them anymore. They are basically used for major groupings of editing features.
A ribbon on the other hand help users understand how commands are used directly and efficiently. It organizes a program’s features into a series of tabs.
