Answer:
collabirations
Explanation
Wikis are designed for collabirations, which is allowing people to contribute more than just posting a response.
Answer:
Option (A)
Explanation:
In the post order traversal, we always print left subtree, then right subtree and then the root of the tree. In preorder traversal, First the root is printed, then, left subtree and at last, right subtree, so, the first element in preorder is the root of the tree and we can find elements of left sub tree from in order as all the elements written left to the root will of left subtree and similarly the right one. This is how repeating it will give the post order traversal.
Lossless compression decreases file size without removing any bits of information. Instead, this format works by removing sameness within data to reduce the overall file size. With lossless, it is possible to perfectly rebuild the original file.
<h3>What utilizes lossless compression?</h3>
Lossless compression is commonly used for so-called "discrete" data, such as database records, spreadsheets, word-processing files, and even some types of image and video information. Text compression is a powerful area for lossless compression.
<h3>
What is lossless compression example?</h3>
Lossless compression methods are reversible. Examples of lossless reduction include GZIP, Brotli, WebP, and PNG, Lossy compression, on the other hand, uses inexact approximations by dumping some data from the original file, making it an irreversible compression process

Answer: ensuring that a system is not changed by a subject that is not authorized to do so
Explanation: Access control refers to pribcues which are employed in the bid thlo ensure the security of data and information. It provides the ability to authenticate and authorize access to information and data thereby preventing unwarranted access and tampering of the information. Integrity in terms of data security and access control is is concerned with modification to an existing or original data by unauthorized sources. When unauthorized addition or subtraction occurs on a data, the integrity of such data has been compromised. Therefore, authorization is required whenever a source is about to access certain information whereby only those with the right authorization code will be allowed, Inputting an incorrect pass code after a certain number of tries may result in system lock down as access control detects a a possible intrusion
