Answer:

Hard drive

Explanation:

The hard drive is where the operating system, programs and data reside on (unless the data is saved and backed up elsewhere). An older hard drive that uses platters for reading and writing data to it will be slower than a later model solid state device. Newer hard drives have very fast access speeds compared to older units.

Question No. 5:

Mkey [24]

Answer:

The answers are:

$a) (1001111)_2 = (79 )_{10}\\b) (11000001)_2 = (C1 )_{16}\\c) (E16)_{16} = ( 3606)_{10}\\d) (56)_{10} = (38 )_{16}\\e) (63)_{10}= (111111 )_2$

Explanation:

a. (1001111) 2 = ( ) 10

In order to convert a base 2 number to base 10 number system the place values are used.

the procedure is as follows:

$(1001111)_2\\=(1*2^6)+(0*2^5)+(0*2^4)+(1*2^3)+(1*2^2)+(1*2^1)+(1*2^0)\\=(1*64)+(0*32)+(0*16)+(1*8)+(1*4)+(1*2)+(1*1)\\=64+0+0+8+4+2+1\\=79$

b) (11000001) 2 = ( ) 16

In order to convert a base 2 number into base 16, group of 4-bits are made starting from right to left

The groups from the given number are:

1100 0001

Then the groups are changed in to decimal/hexa

So,

$(1100)_2 = (1*2^3)+(1*2^2)+(0*2^1)+(0*2^0)\\=(1*8)+(1*4)+(0*2)+(0*1)\\=8+4+0+0=12=C\\\\0001=1$

Writing in the same order in which groups were:

$(C1)_{16}$

c) (E16) 16 = ( ) 10

$(E16)_{16}\\=(E*16^2)+(1*16^1)+(6*16^0)\\=(E*256)+(1*16)+(6*1)\\=3584+16+6\\=3606$

d) (56) 10 = ( ) 16

Dividing by 16 and noting remainders

16 56

3 - 8

So,

The number in base 16 is 38

e) (63) 10 = ( ) 2

Dividing by 2

2 63

2 31 - 1

2 15 - 1

2 7 - 1

2 3 - 1

1 - 1

So the number after converting in base 2 is:

111111

Hence,

The answers are:

$a) (1001111)_2 = (79 )_{10}\\b) (11000001)_2 = (C1 )_{16}\\c) (E16)_{16} = ( 3606)_{10}\\d) (56)_{10} = (38 )_{16}\\e) (63)_{10}= (111111 )_2$
