While Excel is saving your file, it briefly displays a message on the status bar indicating the amount of the file saved.
Then here are the excel features that you need to get a hold of:
Learn to use shortcuts. Once you are able to live without the mouse, you get the speed that counts. There are two types of shortcuts - one where you press a set of keys sequentially - like Alt>H>O>I to adjust column width. And the second where you simultaneously press a combination of keys - like Ctrl+Shift+L for applying filters or Ctrl+1 for the format numbers dialog box. It takes repetition to get the speed but once you are there, you get an edge.
Learn excel functions and apply them to build formulas. Start with easy ones like SUM, COUNT, SUMIF, COUNTIF, IF etc, then move to VLOOKUP, SUMIFS, COUNTIFS, HLOOKUP, INDEX, MATCH, then move to building nested complex formulas like IF inside an IF, VLOOKUP with HLOOKUP, INDEX+MATCH and so on.
Learn about data analysis and data aggregation. This includes tools like Pivot table, solver, goal seek, data tables, descriptive statistics, regression.
Learn about conditional formatting. Style and colour your spreadsheets.
Answer:
192.168.228.0 255.255.255.224
Explanation:
192.168.228.0 255.255.255.128
subnet mask: defines the host and the network part of a ip
CIDR notation : is the shortened form for subnet mask that uses the number of host bits for defining the host and the network part of a ip
For example: 192.168.228.0 255.255.255.128 has CIDR equivalent of 192.168.228.0\25
To have atleast 20 hosts
20 ≤ (2^x) -2
x ≈5
with 5 host bits, we have 2^5-2 = 30 hosts per subnet
and 2^3 = 8 subnets
To get the subnet mask, we have 3 network bits
1110000 to base 10 = 2^7 + 2^6 +2^5= 224
192.168.228.0 255.255.255.224
