Mechanical mouse has a ball that turns rollers inside. If friction is lost between the ball and the mousing surface, or between the ball and the rollers, the mouse fails to work. In order to assure good contact with the mousing surface, the ball must be fairly heavy. When you change directions with the mouse, you must make the ball change rolling directions--an action that inertia likes to prevent.
An optical mouse makes use of an LED and some optics to detect surface texture and the changes in it as the mouse is moved. There are no moving parts
Answer:
DRAM and SRAM
Explanation:
Cache memory is used to reduce the average time to access data from the Main memory.
SRAM is an on-chip memory whose access time is small (fast).
DRAM is an off-chip memory which has a large access time (slow).
A terminology which is used to describe selecting and viewing information stored in a database is known as query.
<h3>What is query?</h3>
A query can be defined as a computational request, selection and view of the data that are stored in a database table, from existing queries, or even from a combination of both a database table and existing queries.
In this scenario, we can infer and logically conclude that query is a terminology that is typically used to describe selecting and viewing of information that are stored in a database.

For this particular attempt, the last stage of the cyber kill chain that Josh performed is: Weaponize.
A cyber kill chain is also referred to as a cyber-attack chain and it can be defined as a series of steps that comprises the stages of a cyber attack. Thus, a cyber kill chain can be used to understand, trace and stop the sequence of events involved in a cyber attack.
Generally, a cyber kill chain comprises seven (7) main stages and these include:
1. Reconnaissance
2. Weaponize
3. Delivery
4. Exploit
5. Install
6. Callback
7. Persist
Weaponize simply involves choosing one or more attack vectors to begin an intrusion into a network system, after gathering sufficient information about the target.
In this scenario, the last stage of the cyber kill chain that Josh performed is weaponize because he decided to investigate other methods of intruding into the system, so as to send his file.
