Which of the following is NOT a method for encoding text characters on a computer?

• ANSI
• ASCII
• SIX-BIT
• EBCDIC 

EXPLANATION

EBCDIC encoding. EBCDIC, in fullextended binary-coded decimal interchange code., Data-encoding system, developed by IBM, that uses a unique eight-bit binary code for each number and alphabetic character as well as punctuation marks and accented letters and non-alphabetic characters. 

ANSI encoding. ANSI encoding is a slightly generic term used to refer to the standard code page on a system, usually Windows. ... This is essentially an extension of the ASCII character set in that it includes all the ASCII characters with an additional 128 character codes.

ASCII, abbreviated from American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices.

A six-bit character code is a character encoding designed for use on computers with word lengths a multiple of 6. Six bits can only encode 64 distinct characters, so these codes generally include only the upper-case letters, the numerals, some punctuation characters, and sometimes control characters.

EXPLANATION

Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM can only be modified slowly, with difficulty, or not at all, so it is mainly used to store firmware (software that is closely tied to specific hardware, and unlikely to need frequent updates) or application software in plug-in cartridges.

You can use Active Directory Sites and Services to force Active Directory replication to occur between two domain controllers on a one-time basis when you want changes to be replicated from the server that received the changes to a server in another site sooner than the site link schedule allows.
As an alternative, you can synchronize replication with all replication partners.

Which version of Apple's desktop OS changed the name from OS X to macOS?

Which version of Apple's desktop OS changed the name from OS X to macOS?

• Sierra
• El Capitan
• Mavericks
• Snow Leopard 

EXPLANATION

Sierra, also known as macOS 10.12, is the 13th version of OS X, released on September 20, 2016. It followed El Capitan (OS X 10.11) and is preceded by macOS High Sierra. Sierra was the first version of OS X that Appleofficially labeled "macOS" instead of OS X.
Like other incremental releases of Apple's desktop operating system, Sierra built on previous versions, incorporating the same user interface and adding several new features. Notably, Sierra was designed to work more seamlessly with other Apple devices, such as iPhones and Apple Watches. For example, Sierra was the first version of macOS to support Universal Clipboard, which allows you to copy something on your phone and paste it on your Mac, or vice versa. It also supports automatic log in to your Mac using an Apple Watch. Safari, the web browser included with macOS Sierra, supports Apple Pay using an iPhone or Apple Watch.
Sierra also increased iCloud integration by syncing the Desktop and Documents folders with iCloud drive. This makes it easier to keep files consistent across multiple Macs. It was also the first version of Apple's desktop OS to include Siri, Apple's voice assistant that was introduced in iOS. Siri can be accessed by clicking the icon in the right side of the menu bar or by pressing and holding Command+Space Bar. You can speak commands, such as "Show my Downloads folder" or "Make the screen brighter," instead of performing the actions with your keyboard and mouse.
NOTE: Before Mac OS X (introduced in 2001), Apple's desktop operating system was called "Mac OS." With the release of Mountain Lion (OS X 10.8) in 2012, Apple changed the name from Mac OS X to just "OS X." The switch to "macOS" with Sierra marks a return to the "Mac OS" name, while using the same naming convention as Apple's other operating systems – iOS, watchOS, and tvOS.
