In general, there and there are many errors (in translation), for example

Extremely disappointed with the publication. The book contains many errors and omissions.
Here is what I found when I reached page 200:
page 69 Table 1.5. Intel processor family. And the table actually lists AVR microcontrollers. The title is not from this table.
page 71 Table 1.6. Basic metric prefixes. Degree signs are missing. 10^-3 became 10-3, 10^3 became 103. Same in appendix B on page 721.
page 106 2.14 4 GB DIMM with eight 256 MB chips... But in the same figure, the caption on the arrow says that the capacity of one memory chip is 32 MB.
page 135 At 8 Gbps ... Frequency unit is wrong.
p. 162 repetition of sentences. "Codes from 0 to 1F (in hexadecimal notation) correspond to control characters that are not printed (Table 2.4). Codes from 0 to 1F (in hexadecimal notation) correspond to control characters that are not printed."
page 163 The ASCII table misplaces characters with codes 70-7A. Uppercase characters are written instead of lowercase.
It seems that there are minor flaws, but they undermine confidence in the study of more serious things in the book, where possible errors are no longer so obvious.
Sloppy edition.

I came across pages 155-156

As a rule, the bandwidth of such a cable is about 750 MHz.

but it's not a mistake, is it? Explain why here ps is calculated in megahertz, and not megabytes?
I myself found errors there, not described here, do translators consider it adequate to release such a raw 6th edition?

Answer 1

For such a thick book, such a short list of errors and misprints? Weird.
Look for more, there are usually more.

Answer 2

Bandwidth shows the number of people either passing through the channel per unit of time.
Quantity is measured in units and time is measured in seconds. We get 1/s = Hz.
Or maybe the author just confused throughput with bandwidth.
