​Axborot tezligi o’lchov birliklari

​ Axborot uzatish tezligi deb, vaqt birligi ichida uzatilgan axborot hajmiga aytiladi. Axborotni uzatish tezligi quyidagi formula orqali aniqlanadi:

​Ikkilik sanoq sistemasida amallarni bajaring:

a) 10010 + 1 · 27 + 1 · 25 + 1 · 23 + 1 · 20 ;

b) 1100 + 1 · 23 + 1 · 21 ;

d) 1001,1 · (1 · 24 + 1 · 23 + 1 · 22 + 1 · 21 );

e) 1111,101 + 1 · 23 + 1 · 2;

f) 1 · 22 + 1 · 21 + 1 · 20 + 10,001;

g) 1 · 20 + 11000111;

h) 1 · 27 + 1 · 23 – 1,1;

i) 11010111 – (1 · 25 + 1 · 23 + 1 · 21 ).

Ikkilik sanoq sistemasidagi ifodalar qiymatini taqqoslang:

a) 1101+11 va 1111+10;

b) 1001,11+101,01 va 1101,01–101,11;

d) 11101–11 va 111+11;

e) 1110,01+101 va 10010,01;

f) 1101 · 1101 va 1011 · 1011;

g) 1101,011–11,01 va 1011,001.

​3. Ikkilik sanoq sistemasida berilgan sonlarni o‘nlik sanoq sistemasiga o‘tkazing:

a) 110110;

b) 101011;

d) 1101010;

e) 1101101;

f) 1101001;

g) 111001;

h) 10001111;

i) 1011110011.

​ Ikkilik sanoq sistemasida amallarni bajarib, natijasini o‘nlik sanoq sistemasiga o‘tkazing:

a) 1001 + 110011;

b) 101101,1 – 111,1;

d) 10101 · (1 · 26 + 1 · 24 + 1 · 21 + 1 · 20 ) ;

e) 1 · 25 + 1 · 20 + 111100011.

d) 10010010001(2) → ?8 ;

e) 32104(8) → ?2 ;

f) 425011(8) → ?2;

g) 777700001(8) → ?2.

​Tetrada kodlash jadvalidan foydalanib, o‘tkazishni bajaring:

a) 10001001011001101(2) → ?16;

b) 101001001001110(2) → ?16;

d) 100000000000101(2) → ?16;

e) 5684000(16) → ?2;

f) 3DADA(16) → ?2;

g) ABCDE(16) → ?2.

​O‘tkazishni bajaring:

a) 101(7) → ?12;

b) 700(8) → ?9;

d) 242(16) → ?9;

e) 455(6) → ?8;

f) 123(11) → ?8;

g) 2240(5) → ?16
