A final number represents the approximate maximum coax length in hundreds of meters. Coax connectors are commonly called UHF connectors because they are rated for frequencies into the UHF (300MHz and up) range before they exhibit noticeable losses. ) Thinnet uses BNC connectors that are easy to connect or disconnect. They both require a terminator at each end to make them appear electrically infinite in length. The terminator is a resistor that absorbs the transmitted energy, avoiding interference-causing reflections.
The more you experiment, the more you will learn and the longer you will retain the material. 4 doesn’t quite illustrate the risk associated with shared variables. Consider a similar example in which the parent bank account manager creates two subtasks: one child process responsible for deposits and the other for withdrawals, each calculating the new balance as part of its processing. Can you see the risk? If two transactions arrive at approximately the same time—one a deposit, the other a withdrawal—a possibility exists, albeit a small one, that one of them will be nullified.
This is a direct application of principles that are often applied to software optimization: time each function, and then time each high-level instruction of the long-running functions to get an idea where the execution time is being spent; then you can optimize that code if possible. Distributed systems can be analyzed as if they were an application, but they are more complex because of the variance in their interprocess communication times on heavily loaded networks. Following are two maxims of system optimization: time is almost always being wasted somewhere other than where you expect, and (the good news) initial efforts are often rewarded with huge gains.
