in a database with a products table and orders table, you want to see which products have not been ordered. what type of query should you create?
To find the products that have not been ordered, you can use a left outer join between the products and orders tables, and then use a filter to only include rows where the order_id column in the orders table is null.
This query will return all rows from the products table, even if there is no corresponding row in the orders table. The result set will include all columns from the products table, and any null values will appear in the columns from the orders table.
You can also use a similar query with a different syntax, depending on the specific database management system (DBMS) you are using. For example, in MySQL you can use a LEFT JOIN instead of a LEFT OUTER JOIN, and in M!crosoft SQL Server you can use a LEFT JOIN with the ON clause replaced by a USING clause.

Exception handling improved performance is not an advantage of Java exception handling.
Exception Handling in Java is one of the most effective ways to manage runtime failures while keeping the application's normal flow intact. Exception Handling in Java is a system for dealing with runtime failures such as ClassNotFoundException, IOException, SQLException, RemoteException, and so on.
An exception is an unwelcome or unexpected occurrence that occurs during a program's execution, i.e. during run time, and disturbs the usual flow of the program's instructions. The software can catch and handle exceptions. When an exception occurs within a method, an object is created. This object is referred to as the exception object. It provides information about the exception, such as its name and description, as well as the program's state at the time the exception occurred.

what does this concurrency setting do when you are editing a lambda function in the lambda console? linkedin aws
Concurrency is the number of requests your function is processing at any given time. When the function is invoked, Lambda allocates that instance to process the event. After the function code has finished executing, it can process another request.
What happens when we reach lambda parallelism?
Lambda functions in a single AWS account within a region share concurrency limits. If your function exceeds the concurrent limit, the Lambda service will not be able to invoke other functions.
What are Lambda concurrency limits?
The default concurrency limit per AWS Region is always 1,000 calls. The default burst concurrency quota per region is between 500 and 3000, depending on the region. There is no maximum concurrency limit for Lambda functions.

Does direction matter while studying?
The environment of a child's room and the direction they study in have a significant impact on how well they perform. The amount of time a child spends studying is not as important as their focus and comprehension abilities.
What is Important Study Room Advice?• The optimal direction for the study room to face is east or west; north is a close second.
• The child should study with his or her back to the east or north, and the east or north wall should be covered with motivational posters, awards, and trophies as well as all of the honors and recognitions the child has received. Their study table shouldn't have a cabinet or a beam over it.
• Avoid placing the door to the study directly behind the chair. Make a wall out of it in its place.
• If it's not possible to have an open space in front of the study table and it must be placed along a wall, leave a small space between them to allow for energy flow.
• Hang a poster on the wall that inspires the child instead of letting them stare at an empty wall in the front.
• To increase the child's ability to concentrate, the study table should be square or rectangular in shape. West and south walls can have bookcases or other storage space; keep the east and north walls light. Books should be kept in a locked cabinet rather than piled up on the study table.
• The computer should be placed either southeast or northwest of the study table, with the table lamp placed on the left side of the table to ensure adequate lighting.
• The study table shouldn't have any mirrors in view because they can be distracting.
• Pale and understated hues should be employed in the study space. It is recommended to choose pastel green for a study room in the north, violet for a room in the north-east, and pale yellow or off white for an eastern room. The most encouraging colors for a study room are ivory, off-white, and white.

Usually, a network interface card is used to link a computer to a router. A separate LAN card is not required today because the majority of modern PCs have NIC cards integrated into the motherboard.
A computer's NIC offers a dedicated, constant connection to a network. It implements the physical layer hardware needed to communicate with a data link layer standard, such as Ethernet or Wi-Fi. Each card functions as a device and has the capacity to organize, transmit, and control the flow of data throughout the network. NICs are directly linked to the motherboard of your computer, either near the USB ports on the back or on the back of the computer (for external network expansion cards) (for onboard NICs). These cards are still extensively used for desktop PCs that lack a motherboard-integrated Ethernet port. Together with other networking devices, NICs are used to establish a connection to a network. Utilizing NICs, only other devices can be connected to. You need a router in order to connect to the internet. Routers are what connect a local network to the internet.

can you use the existing memory modules to upgrade to the maximum amount of supported memory? explain your answer:
Answer:
It is generally possible to upgrade the amount of memory (also known as RAM) in a computer by installing additional memory modules. However, the maximum amount of memory that a computer can support is determined by the motherboard, which is the main circuit board in a computer that houses the processor, memory, and other components.
To determine whether you can use the existing memory modules to upgrade to the maximum amount of supported memory, you will need to check the specifications of your motherboard to see what the maximum amount of memory is that it can support. You can usually find this information in the documentation for your motherboard or by looking up the specifications online.
Once you know the maximum amount of memory that your motherboard can support, you can compare this to the total amount of memory that you currently have installed. If the total amount of memory you have installed is less than the maximum amount of memory that your motherboard can support, you can add additional memory modules to increase the total amount of memory.
It is important to note that you will need to use memory modules that are compatible with your motherboard. This usually means using memory modules with the same type of memory (such as DDR3 or DDR4) and the same physical form factor (such as DIMM or SO-DIMM). You should also make sure that the memory modules you are using are compatible with your processor and operating system.

Which of the following is NOT a type of ransomware?
O Screen locker
O Reverse phishing
O Scareware
O Encryption
Answer:
Reverse Phishing and Scareware
Explanation:
Ransomware is a type of malware that denies access to data files using encryption until a ransom is paid. It comes under the category of cyber extortion. Ransomware does not intend to cause any damage to the computer’s file system instead, it displays a ransom note on the victim’s screen so that the victim can pay a certain amount of money to remove the restrictions and regain access to their computer, usually via a key. The malware creator will either supply a program that can decrypt the files, or will send an unlock code that decrypts the victim’s data. But there is no guarantee that this will happen, even if the requested ransom is paid.
Types of Ransomware
The two major types of ransomware are:
Crypto-Ransomware
Locker Ransomware
Types of Ransomware
Types of Ransomware
Crypto Ransomware:
Crypto ransomware aims to encrypt sensitive files on the victim’s computer. It does not block any basic computer function. This ransomware searches for important files on the local hard drive and external drives of the victim’s system and starts encrypting them. Then, it will present a ransom note to the victim, showing a countdown timer and asking for payment. The attackers generate income by holding the valuable files hostage and demanding a ransom through anonymous methods such as Bitcoin to regain access to these files.

Locker Ransomware:
Locker ransomware locks the victim out of their device and blocks basic computer functions. Some parts of the keyboard may be locked and the mouse can be frozen allowing the victim only to respond to the attacker’s demands. In this case, attackers demand ransom to unlock the device. The locked system only allows limited access, to interact with the attacker.

a graph g is bipartite if its vertices can be partitioned into two sets x and y such that every edge in g has one end vertex in x and the other in y. write a program using an efficient algorithm for determining if an undirected graph g is bipartite (without knowing the sets x and y in advance).
A 2-colorable bipartite graph is always present, and vice versa. no two neighboring vertices have the same color, therefore use several hues.
How do you recognize a bipartite graph? The converse is also true: a bipartite graph is always 2-colorable.Various hues must be used such that no two adjacent vertices share the same color.There will never be a repeating color between any two neighboring nodes.A graph is said to be bipartite if its vertices can be separated into two separate sets, U and V, and every edge (u, v), in that case, either connects a vertex from U to V or a vertex from V to U.To put it another way, either u belongs to U and v to V, or u belongs to V and v to U.Only when a graph G lacks odd cycles can it be said to be bipartite.Proof.Let's assume that G is bipartite first.Odd cycles cannot exist in G because every sub graph of G is also bipartite and odd cycles are not bipartite.To learn more about bipartite graph refer
