Real telecom domain knowledge read quickly useful for software geeks

Let us take any telecom company, they provide 5 kinds of services. One is voice service, Toll free service and the other one is data service. The given domain knowledge in telecom help you understand about telecom domain quickly.

In addition to above, the latest services are Internet service and wireless service. Domain knowledge is crucial to do testing correctly.

Top 5 services
VoiceToll-freeData serviceInternetWireless Voice service: This is standard phone service that you have been using since the first time you called your Grandma to thank her for a birthday present. You need voice service.

Toll-free service: A toll-free number is a special number that enables calls to come in from anywhere without the caller incurring a charge. The called party pays all the charges for the call. How much the called party pays for a call depends on the arrangements made with the long-distance carrier. If you look at all of your voice calls and find that the majority of them are inbound from custome…

HBASE hadoop database really new features to handle growing data volumes

Hbase is Java implementation of Google's Big table. The data stored in HABSE is as shown below. Which is actually two parts.
Row Key : 00001 Column  : (Column Qualifier:Version:Value)Features or key points of HBASE...
HBase data stores consist of one or more tables, which are indexed by row keys.Data is stored in rows with columns, and rows can have multiple versions.By default, data versioning for rows is implemented with time stamps.Columns are grouped into column families, which must be defined up front during table creation. Column families are stored together on disk, which is why HBase is referred to as a column-oriented data storeIn addition...
HBASE is distributed data store,which leverages a network attached cluster of low-cost commodity servers to store and persist data.HBASE architecture is littel trick to know.

Region Servers...
RegionServers are the software processes (often called daemons) you activate to store and retrieve data in HBase.

Python top quiz question to write code for getting output as triangle

The below is the best example for nested loop in Python language. The specialty of this logic is you can create your output in the form of triangle.

Logic in Python
 max = 8  for x in range(1, max + 1):    for y in range(1, x + 1):    print y,    print
Result 1

Python while loop real example explained to use in your project for handling loops

While is one of the loop in Python. The specialty is it never be false. You already know that in my previous post I have shared For Loop in Python. The for loop can be false.


I am giving here one best example:

print("Help! My computer doesn't work!")
while True:
print("Does the computer make any sounds (fans, etc.)")
choice = input(" or show any lights? (y/n):")

In the above logic, while is always true. When in input user can give 'Y/N'

if choice == 'n': # The computer does not have power
    print (" Do not show lights")
if choice == 'y': # It is power plugged in
   print ("show lights")

So, while is always true. Based on input the while loop works. Python is having the below list of Keywords

Python For Loop Example: This Is What Professionals Do

The for loop you need is to print the data you want usually multiple times. For loop, is having two arguments such as variable name and in. I have also given video example in the bottom.

For loop Syntax:
```Pyhton for count in[1, 2, 3]: print(count)print(’Yes’*count) ```First step, How the above syntax works is what I want to share with you. The 'in' represents input array for Python for loop. That means the for loop works 3 times in Python. It displays only 3 times. The third step is just give  'yes', which will multiply with 'count' for 3 times. This is whole story of for loop in Python.

Second step, print just displays values of input that stored in the for loop variable of 'count'. The 'count' gets values one by one from for loop input array.

When you used the Shell to enter a loop, there was a reason that the interpreter waited to respond until after you entered an empty line: The interpreter did not know how long the loop block was going to …

Super Easy Ways To Learn Everything About analytics top books
