comment In my situation, SSD or a new gfx card?
What makes you believe that you need to buy anything at all, and what makes you believe that buying either a new graphics card or a new storage device is the best option in your case?

comment What can I do without admin privileges?
Plenty can be done even without admin access, depending on your threat model. Lack of admin access does however make it harder to make persistent changes to the system-wide configuration and operating system itself, but don't count on it being impossible.

comment Extend or divide network
This has the smell of an exam question. Please edit to describe what exactly you are looking to do ("to extend or to divide a network" is not very precise), what you have tried in order to answer your question on your own, and any other relevant information you can think of to help us focus answers such that they will be most useful to you at your particular level of knowledge.

comment Samsung 18.5" monitor showing coloured line bottom of the screen
It would help if you can edit your question to include the exact model number of your monitor, as well as a photo that shows what you are seeing on the monitor. Post the photo anywhere, include a link in your question, and someone will edit it in.

comment Can a massive MySQL data import on an SSD damage it?
Sectors are traditionally 1 KiB? Citation, please. On rotational drives, two sector sizes are common: 512 bytes (traditional, like on my 4 TB HDDs, in IBM-compatibles dates back to around 1981 or so) and 4096 bytes ("Advanced Format"). File system level allocation units can vary in size, but that's a completely different matter and is purely a file system construct to keep the data structures tracking allocation to a reasonable size in file systems that don't grow them dynamically on an as-needed basis; besides, I doubt fixed 1 KiB block sizes are very common in practice.

"If not, then expect a failure eventually anyway." If the server does use redundant disks, still definitely expect a failure at some point, and plan for it. It's just that with redundancy in place, a single storage device failure has a much lower probability of leading to system downtime.

If you want to discuss this further, please ask a separate question about it so that it can be answered properly.

comment What other IP addresses can/should I use for my home network?
@barlop A smaller-than-/24 is the common globally-routable assignment for leaf sites these days. 10+ years ago I administered two separate IPv4 networks which had been assigned globally routable IPv4 addresses, one /27 and one /28 (same ISP, same customer, different sites). The public netblock at my current workplace is similar; I don't recall exactly, but I think it's a /28. Your initial comment said that "dot 0 is the network address, and dot 255 the broadcast", which holds if and only if the netmask is /24. For any other case, the statement is either (a) misleading or (b) outright false.

When this happens, are you able to surf the Internet from the PCs in question? What happens if you try to ping the printer's IP address?

comment What other IP addresses can/should I use for my home network?
You've got the subnet mask lengths backwards. /8 gives you 24 bits host. You want /24 which gives you 8 bits host (32 total minus 8 and 24 for network, respectively). 192.168/16 is RFC 1918 space, anything less (longer subnet mask) which fully fits within that range is thus also 1918 space.

comment What other IP addresses can/should I use for my home network?
Note: the "private networks" above refers to private residential networks. (Grace period ran out and I'd rather not delete the comment now.) Corporate networks may very well require a shorter netmask to accomodate all the hosts that need to be on a given subnet.

comment What other IP addresses can/should I use for my home network?
If 10.0.0/24 traffic is going to Brazil, your ISP is doing something very weird, and you should call them out on it. Except with special arrangements between the parties involved, 10/8 (like the other RFC 1918 ranges) is supposed to never make it past the egress router of a network.

comment What other IP addresses can/should I use for my home network?
@barlop Addresses ending in .0 and .255 do not indicate the network and broadcast addresses respectively, except in the very specific case where the IPv4 subnetwork ("subnet") mask is exactly 24 bits long. 24-bit netmask length (netmask 255.255.255.0) is a common setup for private networks, but it is not necessary and in fact "classful" IP address assignment has been deprecated since the mid-1990s. These days all IPv4 assignments are CIDR.
