Subject	Description	Subject	Description
Processor	Dual Core has 2 processors. It’s a 32 bit processor & the cache memory is 2 MB.	Processor	Core 2 Duo is 64 bit processor & the cache memory is 4 MB.
Mother Board	There are different variations in AT design. The Baby AT design mother board can usually fit inside a Baby AT case or full AT case.	Mother Board	ATX design uses a different power supply connector and ATX case cools internal components much more efficiently then predecessor.
Graphics Card	It is attached with mother board. PCI cards can access the memory available on the actual card.	Graphics Card	It is attached with mother board. AGP cards can access the system memory to help with complex operations.
RAM	DDR – 2 RAM reduce heat and consumption at higher speeds.	RAM	DDR – 3 RAM runs at higher clock speed as mentioned.
DVD RW/Combo	Sony DRU – 500 A Data transfer rate: 33.3 mb/s MAX Random access time: 160 ms (CD-ROM) 200ms (DVD-ROM) Buffer memory: 8MB	DVD RW/Combo	Sony DRX – 500 ULX Data transfer rate: 480 mb/s MAX Random access time: 160 ms (CD-ROM) 200ms (DVD-ROM) Buffer memory: 8MB
Hard Disk Drive	SATA = Serial ATA Smaller connections & higher data speeds.	Hard Disk Drive	ATA = Advanced Technology Attachment and has speeds of up to 133 Mbps, has a 40 pin connector.
UPS	“Offline” UPS are connected via an electrical relay. In normal operation, the electrical voltage is used to recharge the batteries.	UPS	“Line Interactive” are part of hybrid technology. Indeed, the line connected in parallel via relay but has a micro-processor monitoring the voltage continuously.

Matrix Application

Quiz-3

Following is the input-output table:

	Agriculture(Sale)	Industry(Sale)	Final Demand
Agriculture(Purchase)	3	4	3
Industry(Purchase)	6	10	4

· Find the disposition of sectors’ outputs.

· Find the transaction matrix.

· Find the direct requirement matrix(input-output co-efficient matrix)

· Find the direct and indirect requirement matrix(input output co-efficient matrix)

· What will be the gross production if the demand of the agriculture and industry sector were 8 and 12 respectively?

Solution:

a. Disposition of output of the sectors’ and final output

Total Input Output Table

	Agriculture(Sale)	Industry(Sale)	Final Demand	Total sales
Agriculture(Purchase)	3	4	3	10
Industry(Purchase)	6	10	4	20
Consumer	1	6
Total Sales	10	20

Interpretation:

Out of the production of 10 of Agriculture Sector:

Agriculture Consumes 3 Units.

Industry Consumes 6 Units.

Consumer Consume 1 Unit.

Out of the Production of 20 of Industry:

Agriculture Consumes 4 units.

Industry consumes 10 units.

Consumer consumes 6 units.

B. Inter Sectoral Input and Output Transaction Matrix

Inter sectoral Input and Output Transaction Table

	Agriculture(Sale)	Industry(Sale)
Agriculture(Purchase)	3	4
Industry(Purchase)	6	10

Inter sectoral Input and Output Transaction Matrix

A =

3 4

6 10

Interpretation- Agriculture Sector

Agriculture Sector sale to Agriculture Sector: 3 units

Agriculture Sector sale to Industry Sector: 6 Units

Interpretation – Industry Sector

Industry Sector Sale to Industry Sector: 10 units

Industry Sector sale to Agriculture sector: 4 units.

C. Inter Sectoral Input and Output Co-efficient

Inter Sectoral Input and Output Co-efficient Table

(Dividing column 1 by 10 and column 2 by 20)

	Agriculture(Sale)	Industry(Sale)
Agriculture(Purchase)	0.3	0.2
Industry(Purchase)	0.6	0.5
Consumer	0.1	0.6

Interpretation – Agriculture Sector

Out of 1 unit total sale (Gross sale): Agriculture sale to Agriculture: 0.3, Agriculture sale to Industry: 0.6,

Interpretation – Industry Sector

Out of 1 unit total sale (Gross sale): Industry sale to Industry: 0.5, Industry sale to Agriculture: 0.2,

D. Sectoral direct output (input-output co-efficient matrix)

Table of Input-Output Coefficient

	Agriculture(Sale)	Industry(Sale)
Agriculture(Purchase)	0.3	0.2
Industry(Purchase)	0.6	0.5

Input-Output Coefficient Matrix

A =

0.3 0.2 0.6 0.5

Interpretation:

Out of every 1 unit of gross output of agriculture sector 0.3 are used by the agriculture sector and 0.4 units by industry.

Out of every 1 unit of gross output industry sector 0.2 are used by the industry sector and 0.5 units by agriculture sector.

D. Direct and indirect output matrix (Input-output coefficient matrix)

Formula:

Intersectoral coefficient x Gross Production + Final output = Gross Output

[Matrix of intersectoral coefficients] x [Matrix of Gross Production] + [Matrix of Final Output] = [Matrix of Gross Production]

Where: A: Matrix of intersectoral coefficients X: Matrix of Gross Production D: Matrix of Final Output

AX + D = X

1 0 0 1

If D =

AX + 1 = X

ð AX –X = -1

ð X – XA = 1

ð X(1-A) = 1

ð X = (1- A)^-1

1 0 0 1

0.3 0.2 0.7 0.2

Now, (1 – A ) = =

0.6 0.5 0.6 0.5

Now, Cofactor Matrix of (1 – A )

0.5 0.6

=

0.2 0.7

Hence, Adjoin matrix of ( 1 – A )

0.5 0.2

=

0.6 0.7

Now, Determinants of ( 1 – A )

D = {0.35 – 0.12} = .23

Hence, Inverse Matrix of (1 – A )^-1 = ------ x [Adjoin Matrix]

0.5 0.2

0.23

=----- x

0.6 0.7

2.17 0.87

=

2.61 3.04

If Industry and Agriculture Sector are 8 and 12 Respectively-

2.17 0.87 8

Then the matrix = X

2.61 3.04 12

27.8

=

57.36

Interpretation:

If agriculture and Industry factor are 8 and 12 Respectively

Then Gross Output of Agriculture 27.8 units

Gross Output of Industry 57.36 units
