Question #2 is ridiculous. Its sad that the questions are set up so that you can still get it wrong even though you know all the information. Its like they want you to be better at "taking tests" than being competent.

Unfortunately CompTIA has a history of making questions just like that one. Unless you read the question very carefully you will it wrong. The difficulty is often not the information, but the way the question is worded.

a Windows PC use a little over 8 GB just for the basic OS and a Web Browser. Freshly booted Windows PC, I'm typing this on is using 54% memory for programs (Out of 16 GB), Windows also use extra memory for cache, so it would load the copy of your phones picture library faster with 256 GB (Could be less, depend on how many pictures you have). It's quite a performance issue in a modern PC that the cache and running programs compete for RAM usage. Bottom Line is 8 GB is just to boot your Windows PC, 16 GB to make the Windows PC run better, web usage, very light games (Minesweeper/Tetris level), light app usage. 32 GB, giving 16 GB to the basic OS, Web Browsing, Cache. And 16 GB for games or medium app usage. 64 GB, Streaming, High End Gaming, High End Video Editing, running a few Virtual Machine. (None of it at the same time) 64 GB+ Many Virtual Machines and anything that would be faster in memory due to caching or size of the data worked with. A machine just have the one CPU and you might not want them to compete for the processing power, so you can't simply throw RAM at a problem, at some point your better of with seperate machines. You might want one machine to record streaming, while the other run the game. In use (Compressed) 8,2 GB (1,1 GB) (Compressed is a performance cost to uncompress and compress, so it's not a good thing, but it reduce current active memory usage) Committed 17,1 GB (If I wrote a program and asked it to register 64 GB memory usage, in use wouldn't go up, but Committed would, not until I load data into the 64 GB do it become in use) Free 7,5 GB, Cached 7,5 GB (The cache problem, if I load programs in those 8 GB my cache get used up, slowing down some activities, my games run slower loading data from disk) It's a complicated issue since all things interact, so yeah a faster disk, faster ram, more ram all contribute to a faster running machine compared to the MINIMUM required and it would have been more helpful to actually test or use test information to cover when you would stop gaining and how much gain you get from more+faster, than just saying "640K ought to be enough for anybody"

@itfreetraining
@itfreetraining 24 күн бұрын
You could use a mulitmeter. Set your multimeter to the continuity (beep) mode. With the palm plate disconnected from any power source, touch one probe of the multimeter to the conductive plate of the palm plate and the other probe to a known grounding point. If it beeps it is working. Make sure you ground it again before use.

What is "overhead"?
@itfreetraining
@itfreetraining Ай бұрын
In computer transfers, overhead refers to the extra work or data required to complete the actual data transfer itself. It's like the packaging and administrative tasks involved in sending a box. While necessary for a smooth transfer, the overhead doesn't contribute to the actual content being transferred. Thus, if your data connection has a 10% overhead, the maxium data use you will be able is send 90% since 10% is lost to overhead.

Glad to hear that you like the videos. The most likely culprit is a setting in your computer's BIOS. The BIOS controls the startup behavior of your computer. There might be an option called "Restore on AC Power Loss" or something similar enabled. This setting tells the computer to automatically turn back on when power is restored after a power outage. In some rare cases, a malfunctioning PSU could cause this behavior. The PSU supplies power to all components in your computer. If the PSU has a fault in its circuitry, it might send a signal to the motherboard to turn on even when you haven't pressed the power button.

You might want to add this in...Otherwise I love the whole video which taught me everything else I needed to know. Thanks, JimmyB

I don’t know the cleaner in question, but… I had a fellow student whose homework floppy disk (yes, I’m that old) was unreadable when turned in to the professor two weeks in a row. Upon questioning, the student declared that they had completed each assignment as soon as they got home, then stuck the disk to the fridge (yes, with a magnet) so they wouldn’t forget it when they grabbed their lunchbox. The professor shared the story, not to embarrass the student (didn’t work), but to demonstrate the logical steps in troubleshooting computer issues, including talking through user/customer actions

Interesting story. We were working with a laptop the other day and notice that keys were getting attracted towards the laptop. We worked out the magnets in the speakers in the laptop were doing it. It is surpising how strong they were. So if I work if floppy disks again, I won't put them on top of the laptop.

What does a humanoid cat have to do with anything you're talking about?
@itfreetraining
@itfreetraining Ай бұрын
The cat driving the car is an abstract image about performance problems in that that car is catching fire while driving thus effecting the cars performance. Like a hot computer would effect the performance of the computer. Rather than having a white background, we have been experimenting with different backgrounds. Some of the concepts in computers are pretty abstract so it is hard sometimes to create an image that is not to abstract and shows the concept. This video was done with AI a while ago, since then we have gotten better generating images and also the AI images have gotten better. So we are getting better at having something interesting to look at, but not to abstract the viewer can't understand. We feel we are getting better at getting the right mix with the newer videos. I think you have to be willing to try new things to make your videos better and makes changes as required if it is not working.
