Easily Recognized Language If L = L, a Turing machine M can recognize language L. (M). If TM M exists such that L = L, we say L is Turing-recognizable (or just recognizable) (M). Decidable Words If L = L(M) and M halts on all inputs, language L is determined by Turing machine M.

As a result, a TM only supports one language. It means that for every string sL, M accepts s, and for every string s that M accepts, sL, when we state that a TM M recognizes a language L.

Therefore, consider the definition of decidable languages to gain an understanding of the existence of non-recognizable languages.

They do not overlap each other because of the space between their frequencies.

In the 2.4 GHz band, 1, 6, and 11 are the only non-overlapping channels thus options (c) and (d) are correct.

Bluetooth data is exchanged between gadgets using a frequency band. These bands, which can either be 2.4 GHz or 5 GHz radiofrequency, are used to transmit data. The range (area) and frequency (speed) that these bands offer are the main distinctions between the 2.4GHz and bandwidth bands.

As per the given band = 2.4 GHz band

Only slots 1, 6, to 11 in the 2.4 GHz range don't overlap. To properly configure your connection, choosing one of the following streams is crucial.

The FIFO (First In First Out) algorithm replaces the oldest page in the frame, so the page that was brought in first is replaced first.

For the given page reference string, the FIFO algorithm would incur the most page faults when using three frames, and the Optimal algorithm would incur the least page faults when using four frames. The page fault count for the other algorithms would fall in between these two extremes.

For the given page reference string, the number of page faults that would occur for each of the replacement algorithms, assuming three and four frames, is as follows:

a) FIFO replacement:

With three frames: 9 page faults

With four frames: 8 page faults

b) Optimal replacement:

With three frames: 6 page faults

With four frames: 5 page faults

c) LRU replacement:

With three frames: 8 page faults

With four frames: 7 page faults

The FIFO (First In First Out) algorithm replaces the oldest page in the frame, so the page that was brought in first is replaced first. The Optimal algorithm replaces the page that will not be used for the longest time in the future, while the LRU (Least Recently Used) algorithm replaces the page that has not been used for the longest time in the past.
