Computer hardware and software goes hand in hand. The hardware serves as the body and the software is the mind describing the two in an analogy.

The hardware will not run without the operating software (OS) to connect run each functional part of the computer. The Central Processing Unit computes for the Inputs and Outputs fed to it giving the computer the power to process data coming from all the hardware components receiving the electrical signals translated from the data input from human interaction or other source of data interaction to the computer. To divide we mainly have your hardware components, The Central Processing Unit, The input Peripheral (mouse, keyboard, pen stylus, mics, camera, etc) and your output peripherals (Monitor, Speakers, etc.,). Then we have your software component divided into two. The operating system software (Windows /Mac OS/ Linux / Unix / )and the application software/program (Office applications, Browser etc.,).

What are the two main advantages to a well-designed relational database over other types?

lidiya [134]

The first and the most important advantage is that it supports a simple data structure, mainly tables. Familiar to many users, the table structure is an intuitive organization. Another main advantage of a relational database as compared to others is better security. Once data are split into tables, certain tables can be made confidential.

How do you create a formula in excel

Daniel [21]

Answer:

You can create a simple formula to add, subtract, multiply or divide values in your worksheet. Simple formulas always start with an equal sign (=), followed by constants that are numeric values and calculation operators such as plus (+), minus (-), asterisk(*), or forward slash (/) signs.

Let's take an example of a simple formula.

On the worksheet, click the cell in which you want to enter the formula.

Type the = (equal sign) followed by the constants and operators (up to 8192 characters) that you want to use in the calculation.

For our example, type =1+1.

Notes:

Instead of typing the constants into your formula, you can select the cells that contain the values that you want to use and enter the operators in between selecting cells.

Following the standard order of mathematical operations, multiplication and division is performed before addition and subtraction.

Press Enter (Windows) or Return (Mac).

Let's take another variation of a simple formula. Type =5+2*3 in another cell and press Enter or Return. Excel multiplies the last two numbers and adds the first number to the result.

Use AutoSum

You can use AutoSum to quickly sum a column or row or numbers. Select a cell next to the numbers you want to sum, click AutoSum on the Home tab, press Enter (Windows) or Return (Mac), and that's it!

AutoSum on the Home tab

When you click AutoSum, Excel automatically enters a formula (that uses the SUM function) to sum the numbers.

Note: You can also type ALT+= (Windows) or ALT+ COMMAND += (Mac) into a cell, and Excel automatically inserts the SUM function.
