Let me answer your question with why you should not open an lcd screen without experience and qualifications. Number one, the lcd screen runs on very high voltages that’s why they usually put a sticker on the back that says do not touch, the high voltage can cause ether fatal and non fatal injuries but are very painful ether way. Number 2 it is said that the lcd screen’s liquid crystal contains mercury vapors that can lead to death if not disposed properly. They are fragile, and there is a potential danger of mercury-vapour if the screen leaks some of it. So I recommend you shouldn’t open a lcd screen unless you know what your doing. If your trying to fix a lcd screen it’s too much time and money plus it’s dangerous. Just spend a couple more dollars and instead buy a new display. You can scan the screens bar code it the back to find a replacement. Hope this helps

Answers and explanations:

A) LCD stands for Liquid Crystal Display. The technology is widely used for televisions and other types of displays such as computer screens. Inside, LCDs have a liquid substance partly composed of mercury that changes between red, green, and blue once applied electrical voltage. Every LCD has a multipixel screen so those colors mixed can be portrayed.

B) Even if the mercury levels in an LCD are low, contact with it might cause allergic reactions, rashes or birth defects in pregnant women. That is the reason why somebody who is not technically trained to work with LCDs should not open them. In front of failures, the screen should be handled to the closest technical support.

Determine the number of cache sets (S), tag bits (t), set index bits (s), and block offset bits (b) for a 40964096-byte cache us
pogonyaev

Complete Question:

Determine the number of cache sets (S), tag bits (t), set  index bits (s), and block offset bits (b) for a 4096-byte cache using 32-bit memory addresses, 8-byte cache blocks and a 8-way associative design. The cache has :

Cache size = 1024 bytes, sets t = 26.8, tag bits, s = 3.2, set index bit =2

Answer:

Check below for explanations

Explanation:

Cache size = 4096 bytes = 2¹² bytes

Memory address bit = 32

Block size = 8 bytes = 2³ bytes

Cache line = (cache size)/(Block size)

Cache line = \frac{2^{12} }{2^{3} }

Cache line = 2⁹

Block offset = 3 (From 2³)

Tag = (Memory address bit - block offset - Cache line bit)

Tag = (32 - 3 - 9)

Tag = 20

Total number of sets = 2⁹ = 512

Vilka [71]

Answer:

The change in complex systems can be explained according to the relationship of the environment where the system is implemented.

The system environment is dynamic, which consequently leads to adaptation to the system, which generates new requirements inherent to changes in business objectives and policies. Therefore, changing systems is necessary for tuning and usefulness so that the system correctly supports business requirements.

An example is the registration of the justification of the requirements, which is a process activity that supports changes in the system so that the reason for including a requirement is understood, which helps in future changes
