__Conclusion__: hardware devices work together to perform input, output, processing nad data storage Networks allow computers to share info and resources There are two main categories of software: systems software and application software An OS is a set of computer programs that control the computer hardware to support users’ computing needs

What Are The Differences Between "My Computer" And Windows Explorer?

They perform the same basic function, which is to let you explore the hard-drive(s) of the [|computer]  sitting on your desk. They even both allow you to look at hard-drives on remote computers, if correctly mounted (permissions set).

The main difference are A) the names; B) finding them; C) the [|colour scheme]   Otherwise, you can find most of the same options, viewing, file management, etc. eventually, in the [|menu bars] at the top of each one. Navigation is also "slightly" different.

A) the name difference you already figured out. Once upon a time we had "File [|manager] " on Microsoft systems, which was an even more sensible name for managing files on your local computer, but I guess that got "old".

B) My computer is on the Desktop (computer screen icon), Windows Explorer is in the menu bar from the start button. Confusing, but you get used to it.

C) I suppose the newer colour scheme is smarter. AT least, it's not confusing. = =

**ELECTRONIC RESEARCH PRIMER** Encryption is a software tool that uses scrambling to make data unreadable to anyone other than the intended recipient. It is useful to ensure the privacy of data that you store on your computer, or that you want to email to someone else. Encryption software programs use [|algorithms], or complex mathematical processes, to scramble and unscramble (or "encrypt" and "decrypt") the data. Algorithms work through the creation of [|keys], which are specific strings of data used for encryption. These keys consist of long strings of bits, or binary numbers. The more bits in the key, the greater the number of possible combinations of binary numbers, making the code more difficult to break. You may have heard of "56-bit" or "128-bit" keys, for example. With more bits, the 128-bit key is more difficult to break than the 56-bit key. media type="surveygizmo" key="2J26KTUC4IW39IHKHMRDLI4FB5XER5-102187" width="700" height="500"
