computers have become much much more powerful from the early days of 1960s. back then they filled up entire room or while floor n their computing power added up to less than whats on ur smart watch today.
the increase in computing power is tied to the advance in micro-electronics. the micro-electronics are called integrated circuits (ICs). the IC computing power has been doubled ever year leading to some very powerful computers today.
with the increase in their computing powers, computers have grown to be used on many different things. at first, it was only for military and secret govt projects. now computers are used to keep track of stock prices, manage production lines, monitor people health, calculate taxes and many many other applications.
Answer:
Option (3) is the correct answer of this question.
Explanation:
- HCatalog makes available Hive metadata to users of other Hadoop applications, such as Pig, MapReduce and Hive. it offers interfaces for MapReduce and Pig so that users can read data from and write data to the Hive warehouse.
- This means users don't have to care about where or in what format their data is stored. So we know this way that Hcatalog makes sure our data is secure.
- Others option does not belong to Hcatalog so these options are incorrect .
Answer:
code = 010100000001101000101
Explanation:
Steps:
The inequality yields , where M = 16. Therefore,
The second step will be to arrange the data bits and check the bits. This will be as follows:
Bit position number Check bits Data Bits
21 10101
20 10100
The bits are checked up to bit position 1
Thus, the code is 010100000001101000101
Answer:
b. Automation refers to equipment that complements, rather than replaces, human contact.
4- the type of data in the cell ( alphabetic or numeric)
Explanation:
Sorting refers to arranging the data in ascending or descending order. It can be done alphabetically or numerically. Whereas the filter is set to sieve unwanted records and displays only the desired information.
Follow the below steps to sort through the columns:
- Select the cells in the list to apply sort & filter.
- Click on the Data tab
- Find Sort
- Click the Add Level button, to set the sorting value.
- Select the column in Sort by dropdown from where you want to sort.
For applying a filter,
- Select the cells in the list to apply sort & filter.
- Click on Data tab
