B: Running the hard disk drive utility.
Answer:
B. Running the hard disk drive utility
Explanation:
The disk utility scans the hard disk and other drives for bad or nonfunctional storage blocks on the physical disk. Files that are stored on these bad blocks may become corrupted or inaccessible, so the system tries to identify and move these files before the storage blocks are then disabled.

O A. linking the organization logo to the home page
O B. providing users with different types of navigation elements
OC. providing users with as many choices as space allows
OD. using metaphor to represent real-life objects
Answer:
C
Explanation:
Coming from a purely practical point of view, providing users with as many choices as space allows is a bad idea. You do not want to overwhelm a navigation bar with too many options, especially not "as many choices as space allows". You should keep them short and if need be, categorised.
Hope this helps!
Answer:
multiplexing
Explanation:
Multiplexing is a method by which multiple analog or digital signals are combined into one signal over a shared medium. The aim is to share a scarce resource.
Therefore, multiplexing feature will allow different communication streams to occur at the same time, without having a single data stream using all available bandwidth
Answer:
Hippocampus.
Explanation:
There are two parts of the limbic system. They are the frontal part which is the amygdala and the posterior part which is the hippocampus.
The hippocampus is an extension of the temporal part of the cerebral cortex which is a plastic-like structure that can be easily damaged by stimuli. It is packed with densed neurons and forms an S-shape at the extension of the temporal part.
It is responsible for learning and memory and damage to it can result to memory loss of recently learnt information.
True. In an atomic operation, it's necessary to check separately for the existence of a resource, such as a lockfile, before attempting to create it. This single-step operation maintains atomicity and prevents race conditions.
True. In the case of atomic operations, the correct implementation is indeed to test separately for the presence of the lockfile before trying to create it. Let's explain this in detail. When performing atomic operations, two actions are usually required: checking if a resource (like a lockfile) already exists and then creating that resource if it doesn't exist. However, these two actions must be performed in a single step to maintain the atomicity of the operation and avoid potential race conditions which could occur when multiple processes are trying to access or modify the same resource. Therefore, it is not always necessary to attempt to create the lockfile.
