Answer 2

Here is my detailed answer to your questions:

1. The correct option is B) перфокарты, дискеты, карты памяти. This is because the carriers of information are listed in the order from the oldest to the newest. - Перфокарты (punched cards) were invented in the 18th century and were widely used for data processing and storage until the mid-20th century. - Дискеты (floppy disks) were introduced in the 1970s and became popular in the 1980s and 1990s as a portable and rewritable storage medium. - Карты памяти (memory cards) are a type of flash memory that emerged in the late 1990s and early 2000s and are still widely used today for storing digital data in various devices.

2. The possible bases for the number system used for the number 6374 are 8, 10, and 16. This is because the number 6374 contains only digits from 0 to 7, which are valid in these three systems. - In base 8 (octal system), the number 6374 represents 6*8^3 + 3*8^2 + 7*8 + 4 = 3284 in decimal. - In base 10 (decimal system), the number 6374 represents 6*10^3 + 3*10^2 + 7*10 + 4 = 6374 in decimal. - In base 16 (hexadecimal system), the number 6374 represents 6*16^3 + 3*16^2 + 7*16 + 4 = 25460 in decimal.
