when a deadlock occurs, what is the minimum number of database transactions required? zero one two three all above

Answers

Answer 1

In databases, a deadlock is an undesirable situation in which two or more transactions wait indefinitely for each other to release locks.

What is a deadlock and how does it occur in databases?

In databases, a deadlock is a situation in which two or more transactions are waiting for each other's locks. For example, transaction A locks some rows in the Accounts table and needs to update some rows in the Orders table to complete the operation.

How do transaction deadlocks occur?

A deadlock occurs when two transactions (such as A and B) each need exclusive use of a resource (such as a particular record within a record) that is already part of the other transaction. increase. Transaction A is waiting for resources to become available.

What is the minimum number of threads required to deadlock?

The answer depends on the type of lock or locking mechanism. For reentrant locks, at least two threads are required. (Note that primitive Java locks/mutexes are reentrant). With non-reentrant locks, one thread can deadlock itself by trying to acquire a lock that it already holds1.

Difference between Hollerith and Burroughs machine​

Answers

Explanation:

The tabulating machine was an electromechanical machine designed to assist in summarizing information stored on punched cards. Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census. Later models were widely used for business applications such as accounting and inventory control. It spawned a class of machines, known as unit record equipment, and the data processing industry.

Herman Hollerith (February 29, 1860 – November 17, 1929) was an American businessman, inventor, and statistician who developed an electromechanical tabulating machine for punched cards to assist in summarizing information and, later, in accounting. His invention of the punched card tabulating machine, patented in 1884, marks the beginning of the era of mechanized binary code and semiautomatic data processing systems, and his concept dominated that landscape for nearly a century.

Hollerith founded a company that was amalgamated in 1911 with several other companies to form the Computing-Tabulating-Recording Company. In 1924, the company was renamed "International Business Machines" (IBM) and became one of the largest and most successful companies of the 20th century. Hollerith is regarded as one of the seminal figures in the development of data processing.

the answer is b i believe

The element that should be used only when the content simply references the element is figure. The correct option is B.

What is element of referencing?

The four components of the author, date, source, and title are all included in reference list entries.

There are four referencing conventions that are frequently used. They go by the names of the Modern Languages Association (MLA), American Psychological Association (APA), Harvard, and Modern Humanities Research Association (MHRA) systems.

In computer programming, a reference is a value that allows a program to access a particular piece of data indirectly, such as the value of a variable or a record, in the computer's memory or in another storage location.

As a result, accessing the data is referred to as dereferencing the reference, and the data is referred to as the reference's referent.

Thus, the correct option is B.
