Each table in a database must have at foreign key True False

Answers

Answer 1

The decision to include foreign keys should be based on the specific needs and constraints of the database design.

Each table in a database must have at foreign key True False?

False.

While it is common for tables in a relational database to have foreign keys, it is not a strict requirement. A foreign key is a field in one table that refers to the primary key of another table. This relationship is used to establish a link between the two tables and ensure data integrity.

However, there are cases where a table may not require a foreign key. For example, a table that stores configuration settings may not need to reference data from other tables. In this case, a foreign key would be unnecessary and could potentially complicate the design of the database.

Furthermore, some databases may not even support foreign keys as a feature. For instance, NoSQL databases, which are designed for high scalability and flexibility, often do not rely on traditional relational models and may not have foreign key constraints.

In summary, while foreign keys are a common and useful feature in relational databases, they are not an absolute requirement for every table. The decision to include foreign keys should be based on the specific needs and constraints of the database design.

The ______ service enables users to log into remote computers over the internetbusing their local computers. a. telnet. b. file transfer. c. world wide web. d. usenet

Answers

The answer is "a. telnet." Telnet is a client-server protocol that allows users to access and control remote computers over the internet using their local computer.

It provides a text-based interface for logging into and working on remote computers. Telnet was widely used in the early days of the internet for remote access, but it has largely been replaced by more secure protocols such as SSH. Telnet enables users to connect to a remote computer from anywhere in the world, as long as they have an internet connection. This makes it a valuable tool for system administrators and remote workers who need to access computers or servers from remote locations. However, because it is a text-based protocol, Telnet does not support graphical user interfaces, which can make it difficult to use for some applications. Additionally, Telnet is not secure, as all data transmitted over the connection is sent in clear text, making it vulnerable to interception and hacking.

When oversubscribing threads, not all threads are simultaneously executing.true or false

Answers

True. When oversubscribing threads, not all threads are simultaneously executing.

When a programme produces more threads than the computer's available cores or processors, it is known as oversubscription. Due to the constrained resources, this may result in a situation where not all threads can run concurrently. As a result, the operating system must control the threads and plan their execution on the resources that are available. This may result in resource contention and context switching, which might have an adverse effect on programme performance and add delay. Therefore, when a programme oversubscribes threads, not all threads are guaranteed to be running concurrently.

When removing curNode from a doubly-linked list with at least 2 elements, the list's tail may be assigned with _____.
a. curNode
b. curNode's predecessor
c. curNode's successor
d. null

Answers

When removing curNode from a doubly-linked list with at least 2 elements, the list's tail may be assigned with curNode's predecessor.

So, the correct answer is B.

This is because curNode's predecessor was the node that came before it in the list, and since curNode is being removed, its predecessor becomes the new tail of the list.

It is important to note that if curNode's predecessor was already the head of the list, then the list will have only one element left after curNode's removal.

If curNode's successor was assigned as the new tail, it would mean that the tail is now pointing to a node that has been removed from the list, which would cause issues with accessing and traversing the list. Therefore, curNode's predecessor is the correct assignment for the list's tail.

Hence the answer of the question is B.

It places information in the frame allowing multiple Layer 3 protocols to use the same network interface and media.
It defines software processes that provide services to the physical layer.

Answers

The LLC sublayer, or Logical Link Control sublayer, is a layer in the OSI (Open Systems Interconnection) model that resides between the Data Link layer and the Network layer. Its primary function is to provide reliable data transfer services between two connected devices over a shared communication medium.

One of the key characteristics of the LLC sublayer is that it defines software processes that provide services to the physical layer. These services include the establishment, maintenance, and termination of logical links between devices, as well as error detection and correction mechanisms to ensure the integrity of the data being transferred. Another characteristic of the LLC sublayer is that it allows for the use of different network protocols on the same physical layer. This means that devices with different networking protocols can communicate with each other over the same network infrastructure. Furthermore, the LLC sublayer also provides flow control mechanisms to regulate the flow of data between devices to prevent data loss or congestion. It also handles addressing and framing of data packets, allowing them to be transmitted across the network. In summary, the LLC sublayer is an important layer in the OSI model that provides a range of services to ensure reliable and efficient data transfer between devices. Its software processes, error detection and correction mechanisms, flow control mechanisms, and addressing and framing mechanisms make it a critical component in the communication infrastructure of modern computer networks.

Answers

The number of ternary strings with exactly seven 0's, five 1's, and four 2's is 14,950,736. To see why, we can think about the problem in terms of placing the digits in order. There are 16 total digits in the string, so we need to choose which 7 of them will be 0's, which 5 will be 1's, and which 4 will be 2's.

We can do this using combinations, so the number of ways to choose the positions for the 0's is C(16,7), the number of ways to choose the positions for the 1's is C(9,5), and the number of ways to choose the positions for the 2's is C(4,4). The total number of strings is then the product of these three numbers, which gives: C(16,7) * C(9,5) * C(4,4) = 14,950,736 Therefore, there are 14,950,736 ternary strings with exactly seven 0's, five 1's, and four 2's.

In the linked list implementation we studied, running contains and insert in parallel is not always safe. This is because both operations involve accessing and potentially modifying the list structure, and if multiple threads are executing these operations simultaneously, there can be race conditions and inconsistencies in the list.

To ensure safe parallel access to a linked list, synchronization mechanisms such as locks or atomic operations must be used to ensure that only one thread is modifying the list at a time. Without proper synchronization, it is possible for two threads to simultaneously attempt to insert a node at the same position, resulting in a corrupted list.
