Answer:

ALU :An arithmetic logic unit (ALU) is a digital circuit used to perform calculations and logic operations

Registers:register holds the address of memory where CPU wants to read or write data.

CU:The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor.

BIU:BIU takes care of all data and addresses transfers on the buses for the EU like sending addresses, fetching instructions from the memory, reading data from the ports and the memory as well as writing data to the ports and the memory.

Cache:Cache is used to temporarily hold instructions and data that the CPU is likely to reuse.

FPU:A floating-point unit (FPU, colloquially a math coprocessor) is a part of a computer system specially designed to carry out operations on floating-point numbers.

A*=++a/6+b++ 3 if a=3,b=4

Vinil7 [7]

Answer:

$a=22.5$

Explanation:

Given

$a*=++a/6+b++3$

Required

The result when $a=3$ and $b=4$

Analyzing the given instruction

a*=(++a)/(6)+(b++3)

Single out and solve the expressions in bracket

(++a) = a -- When the ++ operator appears before an operand, it is called pre increment. meaning that the operation will be done before the operand will be incremented.

So: in this case: ++a = a

$b++3 = b + 3$

The operator, as used in that statement is the same as: b + 3.

So:

$a*=(++a)/(6)+(b++3)$

$a*=(a)/(6)+(b+3)$

$a*=(3)/(6)+(4+3)$

$a*=0.5+7$

$a*=7.5$

The above expression is calculated as:

$a=a*7.5$

So:

$a=3*7.5$

$a=22.5$

For a panoramic photograph, you will more than likely want to control the exposure of the photograph yourself rather than lettin

Ronch [10]

When shooting panoramic you would want to control the exposure yourself, much rather than the camera..... A panoramic is one big picture correct, so you would want all of them to be the same exposure level, now some cameras may lock on, and others may not......your correct answer would be TRUE does this make sense?

For an activity with more than one immediate predecessor activity, which of the following is used to compute its earliest finish

laila [671]

Answer:

The correct option is A

Explanation:

In project management, earliest finish time for activity A refers to the earliest start time for succeeding activities such as B and C to start.

Assume that activities A and B comes before C, the earliest finish time for C can be arrived at by computing the earliest start-finish (critical path) of the activity with the largest EF.

That is, if two activities (A and B) come before activity C, one can estimate how long it's going to take to complete activity C if ones knows how long activity B will take (being the activity with the largest earliest finish time).

Cheers!
