Answer: C) Control file
Explanation:
Data dump file is the type of file which contain records of the table and the data in a database. It is also known as database dump which are use for backing up the content of data so that the data can easily be restored incase of data loss.
There are mainly three types of files that are mange by the data pump are:
- Dump file are used to contain data in the database that can be used for move.
- Log file is used to record the messages and data which are associate in an operation.
- SQL file is mainly used to record the output of SQL file instruction.
Therefore, control file is not the type of dump file as it is not associated with the dump file operation.
Answer:
I. Return the laptop to a service center for repair.
II. Substitute an external component for the internal component.
III. Replace the internal component.
Explanation:
A laptop can be defined as a small portable computer that is embedded with a keyboard and light enough to be placed on the user's lap while working.
When a laptop internal device fails, the three options which you can use to deal with the problem are;
I. Return the laptop to a service center for repair: a computer technician at the service center would troubleshoot and fix the problem i.e the internal device that failed.
II. Substitute an external component for the internal component: the user could swap a component found on the outside of a laptop with an internal component provided that they are compatible with each other.
III. Replace the internal component: if the failed internal component is a customer replaceable unit (CRU), you can easily replace it.
Answer:
ii. False
iii. True
Explanation:
Machine and assembly are referred to as a low level programming language used in writing software programs or applications with respect to computer hardware and architecture. Machine language is generally written in 0s and 1s, and as such are cryptic in nature, making them unreadable by humans but easily understandable to computers.
In view of the above, we can deduce that programming in machine level language is very difficult for humans.
Adobe Photoshop is a proprietary software application designed and developed by Adobe inc. for both Windows and MacOS operating system. It is a raster graphics editor that's typically used for imaging and graphics design. It comprises of various shape tools such as ellipse, line, polygon, triangle, custom shape and rectangle.
Generally, the Rectangle tool is used to draw rectangle shape (vector and pixel-based) in Adobe Photoshop.
Answer:
results1 = 1
results2 = 15
results3 = 14
printit = 30
Explanation:
public class HelloWorld{
public static void main(String []args){
int var1 = 0b0001;
int var2 = 0b1111;
int results1 = var1 & var2;
int results2 = var1 | var2;
int results3 = var1 ^ var2;
int printit = results1 + results2 + results3;
System.out.printf("%d %d %d %d", results1, results2, results3, printit);
}
}
Output:
$javac HelloWorld.java
$java -Xmx128M -Xms16M HelloWorld
1 15 14 30
In this program we are performing binary operations with logical gates and binary numbers, to understand the result see each binary operation:
- var1 & var2: refers to the AND gate, since 0001 & 1111 is 0001 our result as an integer is 1
- var1 | var2: refers to the OR gate, since 0001 | 1111 is 1111 our result as an integer is 15
- var1 ^ var2: refers to the XOR gate, since 0001 ^ 1111 is 1110 our result as an integer is 14
- results1 + results2 + results3: refers to the sum of 3 integers, 1+15+14 equal 30
Answer:
value of z is 36.0
Explanation:
Given
Required
Print the value of z
To answer this, I will make use of Python and also provide a manual solution:
The program (in python) is as thus:
<em>v = 4</em>
<em>w = 5</em>
<em>x = 8</em>
<em>y = 2</em>
<em>z = (v + w) * x/y</em>
<em>print (“value of z is “, z)</em>
<em />
Manually, we have:
z = (v + w) * x/y
z = (4 + 5) * 8/2
Solve the bracket
z = 9 * 8/2
z = 9 *4
z= 36
Either ways, the value of z is 36
