A computer that is comparable to a Lada car: It is
slow, most of its features don't work, it takes 10 minutes to start up, but it
will never stop working.
If it is a laptop, it is probably some crappy Lenovo ThinkPad with 2gb of ram. If your'e lucky then the school offers BYOD, so you can use your own actually good laptop. If you're not so lucky, it might even be a Chromebook (i wouldn't even call these laptops)
School desktops are slightly better, but only just. Normally they are used until they
die one
day because no one has cleaned the
dust out of it since 2005 and it overheated.
