Circular error are caused by adding the cell name of a/an cell to aformula

Answers

If you mean a "circular reference error" then you are correct. This error is caused by a formula in a cell that directly or indirectly refers to its own cell. For example, if you place a formula in cell A3 and your formula reads "=A1+A2+A3" you will receive a circular reference warning because the formula contains a reference to the cell that it is in (A3)

Explanation:

A circuit is supplied with 30 VDC and contains three resistors connected in series. The value or R1 is 80 , the value of R2 is 1,000 , and the value of R3 is 4,200 . What is the voltage drop across R2?

Answers

The answer is 5.68 Volts.

So givens are electric supply of 30 VDC and the values of 3 resistors. 

Given:
E= 30 VDC
R1 = 80 Ohms
R2 = 1000 Ohms
R3= 42000 Ohms

And what we are looking for is the voltage on the second resistor.
First we have to get the current of the circuit.

I = E/(R1+R2+R3)
I = 30 / (80+1000+4200)
I = 30 / (5280)
I = 0.00568 A

Then get the voltage V = I x R

V = 0.00568 x 1000
V = 5.68 V

A department store plans to upgrade its IT infrastructure to support a new order-processing application with rich features. The store currently uses eight stand-alone computers when customers check out. The specifications of these computers are:•Quad core processors
•Minimum of one terabyte hard drives
•Minimum of 5 GB RAM
•Windows XP, Linux, or Mac OSX

The management of the store wants to upgrade four of the computers and use them to process client orders. The initial study done by the management reveals that the computers will perform the following tasks:
•Run an order-processing application that requires a multiprocessing operating system. The application will take orders from customers over the Internet, process the orders, and create invoices.
•Communicate with customers using e-mail to resolve customer queries.
•Store customer data on the local computer. The store will use this data to promote new products.

The department store needs you to upgrade the four computers. Find the necessary equipment from online vendors to upgrade the computers

Answers

Assuming price doesn't matter:

Processor: I'd recommend Intel Core i7 or similar
Hard Drive: An SSD with at least 2TB will do
RAM: I'd recommend around 8GB or more
Operating System: Linux is one of the best OSes out there, I'd recommend using that.

___ is the amount of data that a storage device can move from the storage medium to the computer per second.

Answers

Answer:

The answer is "data transfer rate".

Explanation:

The rate of information transfer is the sum of digital information, that travels from one destination to another at a particular time. This can also be viewed as transportation frequency from one place to another one of a given quantity of information. It is the processing power of the larger and specified map, which significantly lowers the data transfer rate.
