Numbers that are greater than or equal to zero in value.
Number systems: This refers to the different ways in which numbers can be represented, including binary, decimal, octal, and hexadecimal.
Binary arithmetic: This refers to the basic arithmetic operations (addition, subtraction, multiplication, and division) using the binary number system.
Unsigned integers: This refers to integers that do not have a sign (i.e., positive or negative).
Bitwise operations: This refers to operations that manipulate individual bits within a binary number, such as AND, OR, NOT, and XOR.
Two's complement: This is a method of representing negative integers in binary, and is widely used in computer systems.
Overflow: This refers to what happens when a calculation results in a number that is too large to be represented within the available number of bits.
Number range: This refers to the range of values that can be represented using a specific number of bits, depending on the number system.
Bit shifting: This refers to the process of moving the bits in a binary number to the left or right, which has the effect of multiplying or dividing the number by a power of two.
Logical operations: This refers to operations that are used to compare two or more bits and produce a result based on the logical relationship between them, such as greater than, less than, or equal to.
Boolean algebra: This is a branch of algebra that deals with logical operations and values, and is used extensively in computer science.
Fixed-point notation: This is a method of representing real numbers in binary, and is widely used in computer systems.
Floating-point notation: This is another method of representing real numbers in binary, and is commonly used in scientific and engineering applications.
Character encoding: This refers to the different ways in which characters (such as letters and symbols) can be represented in binary, and is important for text processing and communication.
Data formats: This refers to the different ways in which data can be structured and stored in computer memory or on disk, and is important for efficient and reliable data processing.
Unsigned Binary: This number system includes only 0s and 1s and represents unsigned integers using a power of 2 representation.
Unsigned Octal: This number system uses base 8 and includes integers ranging from 0 to 7 without including any sign bit.
Unsigned Decimal: This number system uses base 10 and includes unsigned integers only. It is the most commonly used number system as it is the standard arithmetic system.
Unsigned Hexadecimal: This number system uses base 16 and includes digits 0-9 and A-F. It is used to represent numbers in computer systems, especially for addressing memory locations.
Unsigned BCD: This number system is used to represent decimal numbers using binary, with each decimal digit represented by a 4-bit arrangement of binary digits, resulting in a more efficient storage mechanism.
Unsigned Gray code: This code uses binary digits where successive values differ only by one bit. It is used in digital communication, switching circuits, and error detection.
Unsigned Excess-K: This number system uses a shifting of the zero value by adding a positive constant to the input values. It is used in signal processing to convert a signed input value into an unsigned output value.
Unsigned Radix-r: This number system uses base ‘r’ and represents integers ranging from 0 to (r^n)-1. It is used in digital signal processing algorithms.
Unsigned Balanced ternary: This number system uses three digits, -1, 0, and 1 to represent signed integers. It is often used in computer science and mathematics to study the logic of computation.
Unsigned One’s complement: This number system is used to represent unsigned integers using a range of -2^(n-1) to 2^(n-1)-1. For example, in 8-bit systems, it ranges from -128 to 127.
Unsigned Two’s complement: This number system is commonly used in digital systems and is used to represent unsigned integers with a maximum value of 2^(n-1)-1 and a minimum value of -2^(n-1).
Unsigned Zuse Decimal dot notation: This number system is an invention of German computer pioneer Konrad Zuse, it is a floating-point notation that is used to perform arithmetic operations on computers.
