Explain CIA triad

webmaster — Sat, 12 Feb 2022 06:18:41 +0000

CIA stands for Confidentiality, Integrity, and Availability. CIA is a model that is designed to guide policies for Information Security. It is one of the most popular models used by organizations.

Confidentiality

The information should be accessible and readable only to authorized personnel. It should not be accessible by unauthorized personnel. The information should be strongly encrypted just in case someone uses hacking to access the data so that even if the data is accessed, it is not readable or understandable.

Integrity

Making sure the data has not been modified by an unauthorized entity. Integrity ensures that data is not corrupted or modified by unauthorized personnel. If an authorized individual/system is trying to modify the data and the modification wasn’t successful, then the data should be reversed back and should not be corrupted.

Availability

The data should be available to the user whenever the user requires it. Maintaining of Hardware, upgrading regularly, Data Backups and Recovery, Network Bottlenecks should be taken care of.

What is the difference between Rx Lev Full and Rx Lev Sub ? What you mean by Link Budget? Can you explain ?

Editor — Thu, 05 Aug 2021 05:40:10 +0000

RX Lev Full :

RX Lev Full means Mobile transmit the measurement report(SACCH multiframe) for every 480ms.
This multiframe containes 104 TDMA frames, in 104 TDMA frames 4 TDMA frames for Decode the BSIC and remaining 100 TDMA frames for Average measurment of serving cell and neighbouring cell.
This average measurment of 100 TDMA frames are RX Lev Full.

RX Lev Sub :

DTX is a discontinuous trasmission, When the mobile conversation 40% of the time either Transmitter or Receive is idle. When DTX is ON, DTX will switch off the Transmitter or Receiver when they is no speech Pulses.
Only few TDMA frames will transmit, the average of this TDMA frames is called RX Lev Sub, give you proper measurement of RX level.

Link Budget :

A link budget is accounting of all of the gains and losses from the transmitter, through the medium (free space, cable, waveguide, fiber, etc.) to the receiver in a telecommunication system.

What is DITA ?

What is DITA ?

Darwin Information Typing Architecture (DITA) is the most ideal approach to be brilliant about composition and distributing your business content.
DITA is an open standard that portrays the engineering for making and overseeing data that isolates the substance from the arranging, takes into account a progressively streamlined substance creation process, and opens up the potential outcomes of acquainting less difficult methods for distributing with new advancements, as for cell phones. IBM, which created DITA initially, characterizes DITA as pursues:
The Darwin Information Typing Architecture (DITA) is a XML-based, end-to-end design for composing, creating, and conveying specialized data.
This engineering comprises of a lot of structure standards for making “data composed” modules at a subject dimension and for utilizing that content in conveyance modes, for example, online help and item bolster entryways on the Web.

Purpose of DITA

The information put away in your documentation has esteem.
What’s more, whatever has an incentive to the association can be treated as an advantage. Making and afterward leaving that data inside a Word or PowerPoint record seriously constrains what you can do with it, and whatever you can do, you need to utilize manual, kludge approaches to do it.
Making records with conventional instruments in static documents is a wasteful method for composing, refreshing, sharing, and dealing with your data.
DITA is a general methodology that illuminates that wastefulness.
DITA emphatically influences your substance in three principle ways;
It streamlines your substance creation process expands the nature of your substance by institutionalizing it enables you to use your substance in a wide range of ways (reusing it, distributing to numerous configurations, deciphering it effectively)
Despite the fact that there are numerous advantages to DITA, everything comes down to a certain something: being proficient with your substance so you can spare time and cash.

What DITA Is Not

DITA is certainly not a specific device. A wide range of apparatuses enable you to creator in DITA. Truth be told, choosing your instrument set is a piece of the procedure of DITA selection.
DITA isn’t a layout, in spite of the fact that writers regularly use formats to make it considerably quicker and less demanding to compose.
DITA isn’t a style direct, despite the fact that creators surely advantage from one, with or without DITA content.

Why XML ?

Try not to give the XML a chance to part of DITA alarm you.
It’s simply the engineering underneath your substance. Each bit of substance gets put away inside labels-titles, sections, requested records-whatever you have to arrange your substance into a characterized set of theme types.
DITA has a lot of guidelines that state what labels are permitted where, which gives you institutionalization of your substance.
DITA XML at last completes three things.
DITA XML composes your substance into points.
Not all XML does this, but rather DITA has a center arrangement of theme types so you can put the correct kind of data in the correct subject sort, bringing about exceptionally usable substance.
Consider subjects and even the XML inside themes like Lego® squares. You use them in different approaches to fabricate what you require. At last, they meet up to make more than the individual parts.
XML isolates content from configuration, making it compact and adaptable. Your words and your arrangement are never again consolidated, which implies they can be overseen and refreshed autonomously.
For instance, if your marking changes and you have to refresh the text dimension, shading, and style in the entirety of your archives, this will be a focal, once change for any substance put away without organization (in XML).
XML enables the substance to be changed into numerous different arrangements. A great many people creator in XML and after that distribute to PDF, HTML, and either portable or ePub.
It’s additionally conceivable to distribute to places you wouldn’t anticipate, similar to Open Office, Excel, and PowerPoint. You’re constrained just by your creative energy.

What is GUI Testing ?

Editor — Sun, 18 Jul 2021 19:18:52 +0000

What is GUI Testing ?

It is the process of ensure to proper functionality of the graphical user interface (GUI ).
It may also given by the application and making sure it confirms to its written specifications.
GUI testing evaluates design elements such as layout, colors, fonts, font sizes, labels, text boxes, text formatting, captions, buttons, lists, icons, links and content.
GUI testing processes can be either done by the two categories are manual or automatic, and are often performed by third -party companies, rather than developers or end users.
It can be require a lot of programming and is time consuming whether manual or automatic.
Usually the software author writes out the intended function of a menu or graphical button.
GUI testing also tends to test for certain program behaviors that users expect, like an hourglass when the program is busy.

GUI Testing Methods

Manual-based testing.
Record-reply testing.
Model-based testing.

Manual Based Testing

Manual testing is a testing process that is carried out manually in order to find defects without the usage of tools or automation scripting.
A test plan document is prepared that acts as a guide to the testing process in order to have the complete test coverage.

Manual Based Testing

Record and Replay

In this method, GUI testing can be done using automation tools.
This is also been divided by the two parts.
During Record, test steps are captured by the automation tool.
During playback, the recorded test steps are executed on the Application Under Test.
Example of tools – QTP.

Record and Replay

Model Based Testing

In this model, it is a graphical description of a system’s behavior.
It helps us to understand and predict the system behavior.
Models help in a generation of efficient test cases using the system.

What is SDLC ?

Editor — Sun, 18 Jul 2021 19:16:03 +0000

What is SDLC ?

Software Development Life Cycle (SDLC) is a set of phases that provide a common understanding of the software building process.
How the software is realized and developed from the business understanding and requirements elicitation phase to convert these business ideas and requirements into functions and features until its usage and operation to achieve the business needs.
Generally a software engineer should have enough knowledge on how to select the SDLC model based on the project context and the business requirements.
Therefore, it may be required to choose the right SDLC model according to the specific concerns and requirements of the project to ensure its success.
You can think of SDLC models as tools that you can use to better deliver your software project. Therefore, knowing and understanding each model and when to use it, the advantages and disadvantages of each one are important to know which one is suitable for the project context.

What is SDLC

There are some various software development life cycle models defined and designed which are followed during the software development process. These models are also referred as Software Development Process Models”.
Each process model based on a Series of rules unique to its type to ensure success in the process of software development.

Following are the most important and popular SDLC models followed in the industry & miuns

- Waterfall Model
- Iterative Model
- Spiral Model
- V-Model
- Big Bang Model

Waterfall model

The waterfall is a widely accepted SDLC model. In this approach, the whole process of the software development is divided into various phases. In this SDLC model, the outcome of one phase acts as the input for the next phase.
This SDLC model is documentation-intensive, with earlier phases documenting what need be performed in the subsequent phases.

Incremental Approach

The incremental model is not a separate model. It is essentially a series of waterfall cycles.
The requirements are divided into groups at the start of the project. For each group, the SDLC model is followed to develop software.
The SDLC process is repeated, with each release adding more functionality until all requirements are met. In this method, every cycle act as the maintenance phase for the previous software release.
Modification to the incremental model allows development cycles to overlap. After that subsequent cycle may begin before the previous cycle is complete.

V-Model

In this type of SDLC model testing and the development, the phase is planned in parallel.
So, there are verification phases on the side and the validation phase on the other side. V-Model joins by Coding phase.

Agile Model

Agile methodology is a practice which promotes continue interaction of development and testing during the SDLC process of any project.
In the Agile method, the entire project is divided into small incremental builds. All of these builds are provided in iterations, and each iteration lasts from one to three weeks.

SDLC Phases

Phase 1: Requirement collection and analysis
Phase 2: Feasibility study
Phase 3: Design
Phase 4: Coding
Phase 5: Testing
Phase 6: Installation/Deployment
Phase 7: Maintenance

Phase 1: Requirement collection and analysis

The requirement is the first stage in the SDLC process. It is conducted by the senior team members with inputs from all the stakeholders and domain experts in the industry.
Planning for the quality assurance requirements and recognization of the risks involved is also done at this stage.

Phase 2: Feasibility study

Once the requirement analysis phase is completed the next step is to define and document software needs.
This process conducted with the help of ‘Software Requirement Specification’ document also known as ‘SRS’ document.

There are mainly five types of feasibilities checks:

Economic: Can we complete the project within the budget or not ?
Legal: Can we handle this project as cyber law and other regulatory framework/compliances.
Operation feasibility: Can we create operations which is expected by the client ?
Technical: Need to check whether the current computer system can support the software
Schedule: Decide that the project can be completed within the given schedule or not.

Phase 3: Design

In this third phase, the system and software design documents are prepared as per the requirement specification document. This helps define overall system architecture.
This design phase serves as input for the next phase of the model.There are two kinds of design documents developed in this phase,

High-Level Design (HLD)

Brief description and name of each module
An outline about the functionality of every module
Interface relationship and dependencies between modules
Database tables identified along with their key elements
Complete architecture diagrams along with technology details

Low-Level Design(LLD)

Functional logic of the modules
Database tables, which include type and size
Complete detail of the interface
Addresses all types of dependency issues
Listing of error messages
Complete input and outputs for every module

Phase 4: Coding

Once the system design phase is over, the next phase is coding. In this phase, developers start build the entire system by writing code using the chosen programming language.
In the coding phase, tasks are divided into units or modules and assigned to the various developers. It is the longest phase of the Software Development Life Cycle process.
In this phase, Developer needs to follow certain predefined coding guidelines. They also need to use programming tools like compiler, interpreters, debugger to generate and implement the code.

Phase 5: Testing

Once the software is complete, and it is deployed in the testing environment. The testing team starts testing the functionality of the entire system.
This is done to verify that the entire application works according to the customer requirement.

Phase 6: Installation/Deployment:

Once the software testing phase is over and no bugs or errors left in the system then the final deployment process starts.
Based on the feedback given by the project manager, the final software is released and checked for deployment issues if any.

Phase 7: Maintenance

Bug fixing – bugs are reported because of some scenarios which are not tested at all
Upgrade – Upgrading the application to the newer versions of the Software
Enhancement – Adding some new features into the existing software

What is the difference between Angularjs and reactjs ?

Editor — Sat, 10 Jul 2021 19:54:24 +0000

Difference between Angularjs and reactjs

Angularjs	ReactJS
AngularJS is developed with the primary purpose of addressing single page application development.	ReactJS is based on building reusable components of code base which make an app very lightweight, more of a library that makes it quite easy to work with.
AngularJS works with MVC platform.	ReactJS provides us high performance client and server side rendering with a one-way flow for data binding.
AngularJS follows some guidelines, like Angular data binding.In Angular, the Model and the View are linked to allow automatic data synchronization between the two.	React is more of a library than a framework.It can be described as an application view that allows the programmer to utilize reusable components again and again.
Complete Framework AngularJS is complete framework that can run in any browser or platform.	JSX Syntax JSX is a JS syntax that allows developer to use HTML quotes and usage of HTML tag syntax for subcomponents rendering. It promotes building of machine-readable code and provides ability to compound components in one compile-time verified file.
Two-Way Data Binding This property is probably the top feature of AngularJS, as it diffuses the impact after every minor data change and does way with the need for further effort with data sync in View and Model.	Rendering Rendering is the best features of React that gives a significant edge over Angular. The technology comprises smart methods to mitigate the amount of DOM operations, optimize and accelerate the updates process.
