Выберите верные утверждения. •кодирование заключается в том, что каждому символу ставиться в соответствии двоичный код от 0000000 до 1111111 •в процессе вывода символа на экран компьютера производится преобразование кода символа в его изображении •кодирование заключается в том, что каждому символу ставится в соответствии уникальный десятичный код от 0 до 255 •присваивание символу конкретного кода-это вопрос соглашения, которое фиксируется в кодовой таблице.

2 и 4 - точно верные.

В 1 меня смущает точное кол-во цифр в числах.

Задание 1.

3 кбайта= 3*1024*8=24576 бит

1 мбайт = 1*1024*8=8196 байт

4096 бит =4096\8\1024= 0.5 кбайта

2.5 мбайт=2.5*1024=2560 кбайт

Задача 2.

k-120 символов

N(мощность алфавита) = 512=> i=9 бит

I=k*i

I=120*9=1080 бит

Задача 3.

I=2 кб

k=4096 символов

N=2^i        I=k*i                i= 2*1024*8/4096=4

2^4=16 - ответ

Задача 4.

Племя мульти:

N=64 => i=6 бит

Значит 150*6=900 бит          

Племя пульти:                                

N=512 =>i=9 бит

Значит 50*9=450 бит

Задача 5.

I=8 кб

N=16 => i=4

k-?               k=I/i            k=8*1024*8/4=16 384 - всего символов

16 384/512=32 страницы

am Zhilin Andrey. Andrey is my name and Zhilin is my surname. I am seventeen years old. I want to tell you a few words about my family. My family is not large. I have got mother, father and grandmother. There are four of us in the family.

First of all some words about my parents. My mother is a teacher of biology. She works in a school. She likes her profession. She is a good-looking woman with brown hair. She is 44 but she looks much younger.

My father is programmer. He is forty-six. My father often sings and when we are at home and have some free time I play guitar and we sing together. He is also handy with many things. When he was small he liked to take everything to pieces. My grandmother told me a story that once my father tried to repair their kitchen clock but without success. They had to give it to a repairman. But it happened a long time ago. Now he can fix almost everything.

My parents have been married for 18 years. They have much in common, but they have different views on music, books, and films. For example my father likes horror films and my mother likes soap operas. My father is fond of tennis. My mother doesn't go in for sports.

My parents are hard working people. My mother keeps house and takes care of my father and me. She is very good at cooking. My grandmother is a pensioner. She lives with us and helps to run the house. She is fond of knitting.

I want to become a student. I'd like to learn foreign languages. I always try to be in a good mood.

We have got a lot of relatives.
