Answer:
Registry
Explanation:
Windows Registry is used to store the configuration and setting information for hardware and software program which is critical for Windows operation. The registries are structured in hierarchical database model.
Basically, hierarchical database model is akin to a tree format which consist of the parent nodes and their child nodes. For example, a node named as HKEY_LOCAL_MACHINE can possess child nodes HARDWARE, SOFTWARE AND SYSTEM.
The node in the tree is also termed as a key.
The answer is D: Turn yarn into cloth.
During the industrial revolution, a number of new inventions in the textile industry greatly impacted this industry. However, it was the invention of the Spinning Jenny that is credited a lot. It helped move the textile industry from homes to factories and made wool spinning easier and faster. This invention, however, impacted the labor workforce. It reduced the amount of work needed to produce yarn. One worker was able to work 8 or more spools at once and rose to 120 due to technological advancements.
Answer:
d. Port mirror
Explanation:
Port mirroring is a method to monitor network traffic and it is used in the Intrusion Detection Systems. It is also called Switched Port Analyzer and is used to analyse the network errors. This technique basically copies the network packets and sends or transmits these copied packed from one port to another in a network device such as a switch. This means that this technique is used to copy the network packets from one switch port and send the copy of these packets to another port where these packets are monitored. This is how it analyses the network errors and incoming traffic for irregular behavior and also this can be done without affecting the normal operation of the switch and other network processes. It is simple, inexpensive and easy to establish and use. The most important advantage of using mirrored ports is that it catches the traffic on several ports at once or can capture all of the network traffic.
The correct answer is B. Check for sufficient available storage space.
Explanation:
One of the factors that can cause it is not possible to install a new app is insufficient storage as space in the mobile device is needed to save the app. This can be easily solved either by deleting apps and other content or expanding the memory available through a Micro SD card. Also, before attempting any major procedure such as a complete reset it is important to check the storage space availability. In this context, the user should check for sufficient available storage space (option B) because this might be the cause of the issue she is experiencing; also, this is a basic step before considering others such as performing a factory reset.
Answer:
x=2
x=1
x=2
Explanation:
a)
This if statement if (1+2=3) checks if the addition of two numbers 1 and 2 is true. Here the addition of 1 and 2 is 3 which is true. So the condition becomes true.
Since the condition is true x:=x+1 statement is executed. This statement means that the value of x is incremented by 1.
The value of x was 1 before the if statement is reached. So x:=x+1 statement will add 1 to that value of x.
x:=x+1 means x=x+1 which is x=1+1 So x=2
Hence value of x is 2 (x=2) after the execution of x:=x+1
b)
In statement b the value of x will be 1 because both the mathematical operations in the if statement evaluate to false.
which means in b, x:=x+1 will not be executed and value of x remains unchanged i.e x=1
In (c) the value x will be 2 because the condition in the if statement is true. Both mathematical expressions 2+3=5 and 3+4=7 are true. Therefore x:=x+1 will be executed and value of x will be incremented by 1. Hence x=2
