13 meaningful names, and the stories behind them.1JavaBorn in the early 1990s, Sun's smart home Appliance program was developed, such as Interactive TV. Originally named Oak, but Sun's lawyers found that the name had already been registered. Through a series of meetings, the company chose it from a list containing Silk,dna and Java. It is unclear who was the first to suggest the use of Java, but the general speculation was that it was inspired by the Peet coffee shop, because Sun's engineers li

It's important to note that if you think n is the actual number of CPUs, it's a big mistake.In general, we think that a CPU can have multicore, plus Intel's Hyper-Threading Technology (HT), can logically divide the number of CPU core outNumber of logical CPUs = number of physical CPUs x CPU cores This specification value x 2 (if HT is supported and turned on)Note: Linux top view CPU is also the number of logical CPUs ③cpu number of coresThe number of chipsets that c
