EXPLANATION 10110 in binary is the same as 22 in decimal. 10101 in binary is the same as 21 in decimal. 10111 in binary is the same as 23 in decimal. 11000 in binary is the same as 24 in decimal. REFERENCES 2.3 Number Systems2.3 Number System Factsq_itf_numsystems_facts_01.question Question 2: Correct Which of the following notational systems is MOST likely used to represent a MAC address? EXPLANATION The hexadecimal number system uses sixteen digits - the numerals 0 through 9 and the letters A through F. MAC addresses are typically composed of six groups of two hexadecimal digits separated by hyphens or colons. The binary number system works the exact same way as the decimal number system but uses only two digits - 1 and 0. The decimal number system uses ten digits from 0 to 9. The octal number system uses eight digits from 0 to 7.

EXPLANATION 1010101 represents a decimal number with two decimal places that consist of 1s and 0s. The binary number system uses two digits - 1 and 0. In practice, binary numbers do not use decimal points. In fact, the word "decimal" in decimal point refers to the decimal number system. The hexadecimal number system uses sixteen digits - the numerals 0 through 9 and the letters A through F. Octal is a base-8 number system and uses the digits 0 through 7. REFERENCES 2.3 Number Systems2.3 Number System Factsq_itf_numsystems_facts_04.question Question 4: Correct Which single digit has the highest value in the hexadecimal number system? EXPLANATION The hexadecimal number system uses sixteen digits - the numerals 0 through 9 followed by the letters A through F. Question 5: Correct How many bits are in a single byte? EXPLANATION One byte is made of eight bits. Each byte has 256 possible combinations from 00000000 to 11111111. REFERENCES 2.3 Digital Information Factsq_itf_diginfo_facts_01.question Octal Decimal Hexadecimal Binary G0FH9four eight twelve sixteen Question 8: Correct Which of the following transfer rates is the FASTEST? EXPLANATION 1,480 Mbps is equal to 1 Gbps, and so it is the fastest transfer rate listed because it is greater than 1 Gbps. In summary, 1,480 Mbps > 1 Gbps > 181 Mbps > 1,282 Kbps. REFERENCES 2.3 Digital Information Factsq_itf_diginfo_facts_06.question Question 9: Correct Which of the following BEST describes what a kilobyte is a measurement of? EXPLANATION Data storage usually refers to the number of bytes. Storage space on a disk is measured in kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB). Throughput, or data transmission from one computer to another, usually refers to the number of individual bits that can be transmitted in one second. Throughput is measured in kilobits per second (Kbps), megabits per second (Mbps), and gigabits per second (Gbps). The base unit of measure for CPU speed is hertz (Hz) and is recorded in kilohertz (kHz), megahertz (MHz), and gigahertz (GHz). These units of measurement refer to the number of CPU cycles per second, or the number of times per second the processor can write data to memory or read data from memory. Power & sleep options are used to regulate how much electricity a computer system consumes. They determine how long your computer can be idle before turning off the screen or putting it into a low-power sleep mode.

EXPLANATION Unicode is an international 16-bit encoding standard and is capable of representing millions of different characters with enough space for every character from every human language. Developers have even started assigning Unicode values to pictures, called emoji. ASCII is short for American Standard Code for Information Interchange. It is the most common format for plain text files, where each character is represented by a unique 7-bit binary code. Extended ASCII uses an 8-bit binary code and allows for some international characters, but not emoji. Hexadecimal is a numbering system that uses sixteen digits, 0 through 9, and A through F. Binary is a numbering system that uses two digits, 0 and 1. Binary and hexadecimal are NOT encoding schemes.

Which of the following transfer rates is the fastest 181 Mbps 1.24 Gbps 1282 kbps 1480 Mbps?1,480 Mbps(explanation: 1,480 Mbps is equal to 1.48 Gbps and so its the fastest transfer rate listed because it is greater than 1.24 Gbps. In summary. 1,480 Mbps > 1.24 Gbps > 181 Mbps > 1,282 Kbps.
What notational system is most likely used to represent a MAC address?As typically represented, MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or without a separator.
What encoding schemes would be used to represent an emoji?The Unicode Standard has assigned numbers to represent emojis. Here's how it works. In the Unicode Standard, each emoji is represented as a "code point" (a hexadecimal number) that looks like U+1F063, for example.
