 The CREATE statement is used to add a new table to a database. The syntax of the CREATE statement is:

CREATE TABLE table_name ( column1 datatype, column2 datatype, column3 datatype, … );

DSL stands for Digital Subscriber Line, which is a type of broadband internet service that uses copper telephone cabling. A network technician installing an RJ11 connector, which is the standard connector for telephone lines, is most likely using DSL as the network connection type. Fiber, satellite, and cable are other types of internet service, but they use different connectors and cables than RJ11. References: CompTIA IT Fundamentals+ (Exam FC0-U61) Module 4 / Unit 2 / Connecting to a Network, page 6; CompTIA Network+ N10-008 Certification Study Guide, Chapter 2: Network Devices and Cabling, page 55.QUESTION NO: 230

When working with storage. 1,000,000MB can also be notated as:

A. 0.01PB.

B. 1TB.

C. 100GB.

D. 10,000,000KB.

Answer: B

 When working with storage, different units of measurement are used to express the amount of data. The most common units are bytes (B), kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), and petabytes (PB). Each unit is equal to 1,000 of the previous unit, except for bytes, which are the smallest unit. Therefore, 1,000,000MB can also be notated as 1,000GB or 1TB. The other options are incorrect because they are either too large or too small to represent 1,000,000MB. For example, 0.01PB is equal to 10,000GB or 10TB, which is much larger than 1,000,000MB. Similarly, 100GB is equal to 100,000MB or 0.1TB, which is much smaller than 1,000,000MB. And 10,000,000KB is equal to 10,000MB or 0.01TB, which is also much smaller than 1,000,000MB. References:

CompTIA IT Fundamentals FC0-U61 Certification Study Guide, page 71, section 1.6: “A terabyte (TB) is 1,000 gigabytes.”

CompTIA ITF+ Practice Test, question 230: “1TB is the correct answer.”

An incompatible browser is being used: If the browser does not support the technologies or standards used by the online retailer’s website, it might fail to process the transaction properly, leading to issues with page refreshing and confirmation messages.

A pop-up blocker is enabled: Some online purchasing processes may utilize pop-up windows to display confirmation messages. If a pop-up blocker is active, it might prevent these messages from appearing, causing confusion about the transaction's completion.

References:CompTIA IT Fundamentals documentation includes troubleshooting internet connectivity issues and understanding web technologies, where browser compatibility and the impact of browser settings like pop-up blockers on website functionality are discussed.

 A kilobyte is a unit of digital information that equals 1,024 bytes. A byte is the smallest unit of data that can be stored or processed by a computer. A kilobyte can store a small amount of text, such as a few sentences or a paragraph. Storage devices, such as hard disks and flash drives, use kilobytes and other larger units, such as megabytes and gigabytes, to measure their capacity and performance. References: The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 38.

 HDMI and VGA are the connectors that should be available in the conference room to ensure everyone can use the conference room projectors. HDMI and VGA are types of video connectors that are used to connect a video source, such as a laptop, to a video output, such as a projector. HDMI stands for High-Definition Multimedia Interface, which is a digital connector that can transmit high-quality video and audio signals over a single cable. VGA stands for Video Graphics Array, which is an analog connector that can transmit standard-definition video signals over a 15-pin cable. HDMI and VGA are common video connectors that are found on old and new laptops, respectively. Having both HDMI and VGA connectors in the conference room can ensure compatibility and connectivity for different laptops and projectors. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 40.

Failover is a technique that ensures high availability of databases by switching to a backup or standby server in case of a primary server failure. Failover can be automatic or manual, depending on the configuration. Failover can prevent data loss and downtime for critical applications that rely on databases. References: The Official CompTIA IT Fundamentals (ITF+) Student Guide (Exam FC0-U61), Chapter 5, Section 5.3, Page 222.

A concurrent license is a type of software license that allows a software program to be installed on as many computers as the company wants, but only a limited number of users can use the software at the same time. A concurrent license is based on the number of simultaneous users rather than the number of installations. A concurrent license can help a company save money and resources by sharing the software among multiple users who do not need to use the software all the time. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 211.

Using private browsing (or "incognito mode") while accessing sensitive information on a public computer is the best approach to prevent others from seeing what was done during that session. Private browsing does not save a record of browsing history, cookies, or form data, effectively ensuring that subsequent users of the public computer cannot easily retrieve this information from the browsing session.

References: Internet security practices, including the benefits of private browsing, are typically included in CompTIA IT Fundamentals documentation, which covers essential cybersecurity measures for protecting personal information.

RAM stands for Random Access Memory, which is where the changes are located before they are saved to permanent storage when editing a document. RAM is a type of volatile memory that stores data temporarily while the computer is running. RAM allows fast access and modification of data by the CPU, but it loses its contents when the power is turned off. SSD stands for Solid State Drive, which is a type of permanent storage that stores data persistently even when the power is turned off. SSD uses flash memory chips to store data, which offer faster performance and lower power consumption than traditional hard disk drives (HDDs). CPU stands for Central Processing Unit, which is the main component of a computer that executes instructions and performs calculations. CPU does not store data, but it uses registers and cache memory to hold data temporarily during processing. GPU stands for Graphics Processing Unit, which is a specialized component of a computer that handles graphics and image processing. GPU does not store data, but it uses dedicated memory to hold graphics data temporarily during rendering. References: The Official CompTIA IT Fundamentals (ITF+) Student Guide (Exam FC0-U61), Chapter 1: IT Fundamentals

Device Manager in Windows is a system utility used to view and control the hardware attached to the computer. It allows users to uninstall, disable, and update device drivers, as well as scan for hardware changes. This utility is essential for managing the interactions between a computer’s operating system and its hardware components.References: This functionality is outlined in various IT certification materials, including CompTIA's documentation which emphasizes understanding system utilities for effective IT support.
