Lesson 6 Flashcards
is a department of computer engineering, that contracts with methods of representing integers and actual values.
Computer Arithmetic
is a fundamental division of Mathematics, that is involved with numbers and their actions.
Arithmetic
Arithmetic is a different name given to
number theory
There are 4 basic operations of arithmetic:
Addition, Subtraction, Multiplication, and Division
is the most essential operation of arithmetic.
Addition
It is the opposite process of addition.
Subtraction
is known as recited addition
Multiplication
is the reverse of multiplication.
Division
a numeration system in which a real number is represented by an ordered set of characters where the value of a character depends on its position.
Number representation
are systems in mathematics that are used to express numbers in various forms and are understood by computers.
Number systems
it is a mathematical value used for counting and measuring objects, and for performing arithmetic calculations.
Number
There are 4 various types of number systems that have different properties:
- binary number system
- the octal number system
- the decimal number system
- the hexadecimal number system
is the system that we generally use to represent numbers in real life.
Decimal Number System
This system is used in computers to reduce the large-sized strings of the binary system.
Hexadecimal Number System
Given below is the different types of data that computer uses:
Numeric data and Non-numeric data
Numeric data
It can be of the following two types:
Integers and Real Numbers
is a number with no decimal or fractional part and it includes negative and positive numbers, including zero.
Integers
is any form of data that is measured in non-number (or word) form. It makes use of symbols and letters. Such data can only be identified in a word format.
Non-numeric data
Types of non-numeric data:
- Character data
- Character set
- Data Address
- Logical Data
A sequence of character is called
character data
means the string of alphanumeric characters on a distributed or other electronic network or database which may be accessed only by knowledge or possession of a private key to facilitate or record transactions on the distributed or other electronic network or database.
Data Address
is used by computer systems to take logical decisions.
Logical Data
is represented by a dot or square on a computer monitor display screen.
pixel
is a special symbol or word that connects two or more phrases of information.
Logical Operation
are simple words (AND, OR, NOT or AND NOT) used as conjunctions to combine or exclude keywords in a search, resulting in more focused and productive results.
Boolean Operators
is a type of flash memory based on NAND logic gates.
NAND Flash
is a type of flash memory based on NOR logic gates.
NOR Flash
The 3 functional units of the CPU are:
- Control Unit (CU)
- Arithmetic Logic Unit (ALU)
- Memory Unit (MU)
is said to be the mathematical brain of the microprocessor.
ALU
handles all of the following computer numerical operations.
arithmetic unit
performs logical operations (e.g., AND, OR, and NOT) and numeric tests like checking if a number is a negative number.
logic unit
moves each digit in a number’s binary representation left or right.
bit shifting operations
There are 2 main types of bit-shifting operation:
- Logical Shifts (Left Shift and Right Shift)
- Arithmetic Shifts (Left Shift and Right Shift)
can be used for dividing or multiplying an integer variable.
Arithmetic Shift operations
is said to be the brain of the computer system.
microprocessor or CPU
used to execute the program
Program Execution
used to control the operations performed by the computer.
Hardware and Operations Control
is basically an integrated circuit chip and it is the crucial component of a computer system.
CPU
The CPU consists of 3 functional units:
- Control Unit (CU)
- Arithmetic Logic Unit (ALU)
- Memory Unit (MU)
MIPS stands for
Microprocessor without Interlocked Pipeline Stages.
