Answer:
True
Explanation:
A computer can be defined as an electronic device that is capable of receiving of data in its raw form as input and processes these data into information that could be used by an end user.
Generally, a computer is composed of five (5) main components and these include;
I. Input unit.
II. Output unit.
III. Central processing unit (CPU).
IV. Storage (memory) unit.
V. Power supply unit (PSU).
A power supply also referred to as power supply unit (PSU) can be defined as a hardware component of a computer that converts and step-down the domestic alternating current (AC) electrical power to a low-voltage regulated direct current (DC) power, so that the internal components of a computer can be supplied with power.
Hence, the power supply unit (PSU) serves as a rectifier by converting alternating current (AC) house current to direct current (DC) and as a transformer to step-down voltage from 220 Volts or 110 Volts to 50, 30, or 20 Volts depending on the requirements of a computer.
Answer:
- def convertStr(num):
- Number = ("One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine")
- numStr = str(num)
- output = ""
-
- for x in numStr:
- index = int(x) - 1
- output += Number[index] + " "
-
- return output
-
- value = 1234
- print(convertStr(value))
Explanation:
Firstly, create a function convertStr that take one input number (Line 1).
This function convert the input number to string (Line 3) and then use for-loop to traverse through the individual digit (Line 6). In the loop, get the target index to extract the corresponding digit letter from the Number tuple(Line 7). The target index is always equal to the current digit number - 1. Next, join the extracted digit letter from the tuple to an output string (Line 8) and return it at the end of the function (Line 10).
We test the function using 1234 as argument (Line 12 - 13) and we shall get One Two Three Four
Answer:
Select commands would return all the rows and columns in the table.
Explanation:
In the database management system, it consists of one or more table. To handle this table it provides the concept of SQL(Structured Query Language). It is a programming language that design, manage, store data into the relational database. It is case sensitive language. In the SQL many commands used for handle table data, it returns all rows and columns from the table.
Syntax of select command can be given as:
Select * from tablename;
Example:
select * from ProductCategory;
returns all the data from the table.
In select command, we will also return select data by using condition
SELECT column1 [, column2, ...]
FROM tablename
WHERE condition
In the conditional clause we use these operators that can be given as:
= Equal, > Greater than, < Less than, >= Greater than equal to, <= Less than equal to, != Not equal to.
<u>False:</u>
A website about anything political from one end such as the political party or candidate is most likely to give biased information such as
- I will be the best mayor you ever had (Opinion)
- I will never let you down (Opinion)
- I have the best house (Opinion)
This is because those are Opinions not facts which is bias-based information.
