FC0-U61 Dumps with Practice Exam Questions Answers

The exact number of bytes in a gigabyte is 1.073.741.824 bytes. A byte is a unit of digital information that consists of eight bits. A bit is a binary digit that can have one of two values: 0 or 1. A byte can store one character, such as a letter, a number, or a symbol. A gigabyte is a unit of digital information that consists of 1.073.741.824 bytes or 1.024 megabytes. A megabyte is a unit of digital information that consists of 1.048.576 bytes or 1.024 kilobytes. A kilobyte is a unit of digital information that consists of 1.024 bytes. These units are based on the binary system, which uses powers of two to represent values. However, there are also decimal units that use powers of ten to represent values, such as gigabyte (GB), megabyte (MB), and kilobyte (KB). These units are often used by storage devices and network services to measure capacity or speed. In this case, one gigabyte (GB) equals 1 billion bytes or 1.000 megabytes (MB). One megabyte (MB) equals 1 million bytes or 1.000 kilobytes (KB). One kilobyte (KB) equals 1 thousand bytes. References: The Official CompTIA IT Fundamentals (ITF+) Student Guide (Exam FC0-U61), Chapter 2: IT Concepts and Terminology

 Password complexity and password history are two practices that are being employed by the IT department to establish a new password policy for employees. Password complexity is the requirement that passwords must contain a combination of different types of characters, such as letters, numbers, and symbols. Password complexity makes passwords harder to guess or crack by attackers. Password history is the record of the previous passwords used by a user. Password history prevents users from reusing the same passwords over and over again, which reduces the risk of compromise. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 208.

 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.

Disk encryption is a type of encryption that protects the entire contents of a hard drive or a removable storage device by using a secret key to scramble the data. Disk encryption would best protect a laptop computer in the event of theft because it would prevent unauthorized access to the data on the laptop. Email, VPN, and HTTPS are not types of encryption that protect the entire contents of a laptop computer. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 8: Security Concepts, page 308.

Thunderbolt is an interface that supports both video and data. Thunderbolt is a high-speed serial interface that can connect multiple devices to a computer using one cable. Thunderbolt can support both DisplayPort and PCI Express protocols, which means it can transfer both video and data signals simultaneously. Thunderbolt can also provide power to connected devices and support daisy-chaining up to six devices per port. Thunderbolt offers faster data transfer rates than USB or FireWire interfaces. VGA is an interface that supports only video. VGA stands for Video Graphics Array, which is an analog interface that can connect monitors to computers using 15-pin connectors. VGA can only carry video signals and does not support audio or data transfer. VGA also has lower resolution and quality than digital interfaces such as HDMI or DVI. DVI is an interface that supports only video as well. DVI stands for Digital Visual Interface, which is a digital interface that can connect monitors to computers using 24-pin connectors. DVI can carry either analog or digital video signals depending on the type of connector used (DVI-A for analog, DVI-D for digital, or DVI-I for both). DVI does not support audio or data transfer either. FireWire is an interface that supports only data.
