Explanation:
Concurrency Control in Database Management System is a procedure of managing simultaneous operations without conflicting with each other. It ensures that Database transactions are performed concurrently and accurately to produce correct results without violating data integrity of the respective Database.And The ACID properties, in totality, provide a mechanism to ensure correctness and consistency of a database in a way such that each transaction is a group of operations that acts a single unit, produces consistent results, acts in isolation from other operations and updates that it makes are durably stored.
Answer:
This is important to understand the basic ways to store pictures and video in a computer because both of them consume a relatively large storage spaces in a the computer compared with normal text files.
Explanation:
Nowadays, many computers shipped with a SSD drive (Solid State Drive) with only around 256 - 512 Gb. With this capacity, the storage spaces left to store the pictures and video are very limited after installation of the essential software.
One common way to store pictures and video is to save them at an external hard drive. Another option is the cloud storage service such as Google Drive, Google Photo etc. These storage mediums obviate the need to store those media files into the local computer machine.
Answer:
Option a. int max = aList.get(0); for (int count = 1; count < aList.size(); count++) { if (aList.get(count) > max) { max = aList.get(count); } }
is the correct code snippet.
Explanation:
Following is given the explanation for the code snippet to find largest value in an integer array list aList.
- From the array list aList, very first element having index 0 will be stored in the variable max (having data type int).
- By using for starting from count =1 to count = size of array (aList), we will compare each element of the array with first element of the array.
- If any of the checked element get greater from the first element, it gets replaced in the variable max and the count is increased by 1 so that the next element may be checked.
- When the loop will end, the variable max will have the greatest value from the array aList.
