Difference Between Data and Metadata
Metadata is a form of Data, but both are not the same. Data and metadata are used for different purposes and have different specifications. Data is simply defined as a set of raw facts and figures, while metadata is one that provides relevant information about the data. Read this article to learn more about data and metadata and how they are different from each other. What is Data? Raw facts and figures obtained from an observation, measurement, etc. are called data. Data makes the basis of processing. For a user, raw data may not always be meaningful. Data is first ...
Read MoreDifference Between COCOMO 1 and COCOMO 2
COCOMO 1 and COCOMO 2 are two cost estimation models, developed by Barry Boehm. These two cost estimation models are used for computing the cost of software development. The most basic difference between these two models is that the COCOMO 1 model helps to provide the estimates required for the efforts and schedule, whereas the COCOMO 2 model provides the estimates that represent a standard deviation near the most likely estimate. Read this article to learn more about the COCOMO 1 and COCOMO 2 models and how they are different from each other. What is COCOMO 1? COCOMO 1 was the first model developed ...
Read MoreDifference between CALL and JUMP instructions
A CALL instruction is used to call a subroutine, while a JUMP instruction updates the program counter value and makes it point to another location inside the program. Read this article to learn more about CALL and JUMP instructions and how they are different from each other. What is a CALL Instruction? A CALL instruction is utilized to call a sub-routine. Using a CALL instruction, the program control is transferred to a location in memory that is not a part of the main program. A CALL instruction necessarily requires the initialization of a Stack Pointer (SP). It is basically ...
Read MoreDifference between Byte Addressable Memory and Word Addressable Memory
Memory plays a vital role in any computer system and it is very important to understand how it works and how it stores the data. In general, we know that computer memory stores the data after converting into bits or bytes (which is nothing but collection of bits). In this article, we are going to explain how this storage take place and how to address those storage blocks. Data, or in simple language, every word that we provide to a computer system is being stored in a memory, whether in temporary cache or permanent memory. But before storing it to ...
Read MoreDifference Between Bubble Sort and Selection Sort
The task of arranging elements of an array in a particular order is referred to as sorting. The sorting of an array or a list is mainly done to make the searching easier. There are two types of sorting algorithms namely, Bubble Sort and Selection Sort. Bubble sort performs sorting of data by exchanging the elements, while the selection sort performs sorting of data by selecting the elements. Read this article to learn more about bubble sort and selection sort and how these two sorting techniques are different from each other. What is Bubble Sort? Bubble sort is a simple ...
Read MoreDifference Between B-tree and Binary tree
There are two types of non-linear data structures namely, B-Tree and Binary Tree. These two terms sound similar but they are absolutely different from each other. The most basic difference between a B-Tree and a Binary Tree is that a B-Tree is used for data storage on a disk, whereas a Binary Tree is used for data storage in RAM. Read this article to learn more about B-tree and Binary Tree and how they are different from each other. What is a B-Tree? B-Tree, also called Balanced Sort Tree, is a type of balanced M-way tree. In a B-tree, the ...
Read MoreDifference Between Array and Structure
Arrays and Structures are two different types of container datatype. The most basic difference between an array and a structure is that an Array can contain the elements of same datatype, while a Structure is a collection that can contain the elements of dissimilar datatypes. Read this article to learn more about Arrays and Structures and how they are different from each other. What is an Array? An array refers to a collection that consists of homogenous elements, i.e. of same data type. Arrays are declared using '[]'. It uses subscripts/ '[ ]' (square brackets) to access the elements. An ...
Read MoreDifference Between Array and Linked List
The basic difference between an array and a linked list is in their structure. An array relies on the index-based data structure, whereas a liked list is based on the references. Read this article to find out more about Arrays and Linked Lists and how they are different from each other. What is an Array? An array is a consistent set of fixed number of data items. Array stores elements in contiguous memory locations. This means the specific elements can be accessed using easily calculable addresses. Hence, an array provides fast access to find element at a specific index. Another ...
Read MoreDifference between Alpha and Beta Testing
Alpha and Beta testing are types of testing which are based on feedback from real customers using real products in real environments, but they are driven by distinct goals and processes. Read this article to find out more about Alpha and Beta testing and how they are different from each other. What is Alpha Testing? Alpha testing is the testing that is performed at the developer's site by the internal teams, before releasing the product to the external customers. The primary goal of alpha testing is basically to find bugs, and determine does the product work how it is expected ...
Read MoreDifference Between Abstraction and Data Hiding
In object oriented programming (OOP), abstraction and data hiding are two important concepts. Abstraction is a process of extracting important information without involving the complete detail of the system. On the other hand, data hiding is a process of wrapping the data in a single unit, i.e., to achieve data encapsulation. Read this article to learn more about abstraction and data hiding and how these two concepts are different from each other. What is Abstraction? Abstraction, or data abstraction, is one of the object-oriented methodologies. Abstraction is defined as the process of hiding the internal implementation and keeping the complicated ...
