1. Functional units of a digital computer include storage units, central processing unit (CPU), and input and output units.
To answer this question, we refer to the given text that states that the functional units of a digital computer are organized as follows: 1) storage units, 2) central processing unit, and 3) input and output units.
2. The central processing unit (CPU) consists of various units, including control unit, arithmetic and logic unit (ALU), and registers.
Although the text does not explicitly mention all the units that make up the CPU, it states that the examination of the central processing unit follows the discussion of primary and secondary storage units. Thus, we can conclude that the CPU is the second functional unit after the storage units.
3. Computer system organization is structured around the primary storage unit.
According to the text, all data and instructions used by the computer system must pass through primary storage. Therefore, the organization of a computer system revolves around the primary storage unit.
4. The two main types of storage units are primary storage and secondary storage.
The text explicitly states that there are primary and secondary storage units in a computer system.
5. Primary storage contains all data to be processed, intermediate results, final results, and instructions required for ongoing processes.
The text explicitly mentions the functions of primary storage, which include storing all data to be processed, intermediate results, final results, and instructions required for ongoing processes.
6. The function of primary storage is to hold data and instructions that need to be processed.
This information is explicitly provided in the text, which states that primary storage holds all data and instructions that need to be processed.
7. Primary storage is often called memory because of its similarity to a function of the human brain.
The text specifically mentions that primary storage is often referred to as memory because of its similarity to the function of human memory.
8. Computer memory differs from human memory in retaining large numbers of symbol combinations without forgetting or changing any details, and it can locate all its contents quickly upon demand.
As stated in the text, computer memory differs from human memory in its ability to retain large numbers of symbol combinations without forgetting or changing any details and its ability to locate all contents quickly upon demand.
9. Codes used in computer memory are based on a binary number system, which has two possible values: 0 and 1.
The text explains that codes used by computer designers are based on a binary number system that has only two possible values, 0 and 1.
10. Secondary storage is slower and less expensive than primary storage, and it is used to store large amounts of data that cannot fit in primary storage.
According to the text, secondary storage is slower and less expensive than primary storage. It is used to store large amounts of data that cannot fit in the primary storage.
Пожалуйста, вот подробное решение с обоснованием выбора ответов:
A. The librarian is surprised to see Nick because he 1) doesn't like to read 2) came back too soon 3) hasn't been to the library before
Обоснование: В диалоге никак не указывается, что Ник не любит читать. Диалог указывает на то, что библиотекарь удивлена, видя Ника. Она пытается понять, почему он так рано вернулся. Поэтому правильный ответ: 2) came back too soon (вернулся слишком рано).
B. Nick read the first book of "Harry Potter" in 1) a week 2) 3 days 3) 4 days
Обоснование: В диалоге, Ник говорит, что прочитал первую книгу "Гарри Поттера" за "несколько дней". "Несколько" в данном контексте обычно объективно означает число, близкое к трём. Следовательно, правильный ответ: 2) 3 days (3 дня).
C. Nick is NOT planning to read 1) a comic book 2) the first book of "Harry Potter" again 3) the second book of "Harry Potter"
Обоснование: В диалоге, Ник говорит, что не планирует читать "комикс" снова. Следовательно, правильный ответ: 1) a comic book (комикс).
D. Sarah McGregor 1) is a new librarian 2) writes books 3) draws pictures
Обоснование: В диалоге, библиотекарь называет себя Сарой МакГрегор. Нигде в диалоге не указано, что она пишет книги или рисует картинки. Следовательно, правильный ответ: 1) is a new librarian (является новым библиотекарем).
E. Nick will come to the library tomorrow to 1) learn how to draw 2) get a new book to read 3) meet his old friends
Обоснование: В диалоге, Ник говорит, что придёт завтра в библиотеку, чтобы "взять новую книгу для чтения". Следовательно, правильный ответ: 2) get a new book to read (взять новую книгу для чтения).
Таким образом, записываем выбранные цифры под соответствующими буквами в таблицу:
