              Android Architecture Stack

              Hello Everyone! In this article we are discussing about the android architecture. It is essential for all the android application developers to understand the android architecture to get a clearer idea about the structure on which the application is made. From the exam point of view, the android architecture stack question has been asked several times (sometimes along with the Dalvik Virtual Machine ). Android operating system is a stack of software components which is roughly divided into five sections and four layers. The five sections of android architecture are- Linux kernel Libraries Android Runtime Application Framework Applications This is a layered architecture with each section having a different functionality. A) Linux Kernel - It is the bottom most layer of the architecture. This is the kernel on which android is based. This layer provides a level of abstraction between the hardware devices. It also contains all the l...

              UML - Use Case Diagram for Vending Machine

              Hello Everyone! Here is an example of an Use case Diagram of a Vending Machine System. Problem Statement - A vending machine accepts coins for variety of products. The user selects the drinks from products available through selection panel. If the drink is available the price of the product is displayed. The user then deposits the coins depending on the price of the product. Coin collector collects coin after stipulated time the controller will compare the deposited coin with price. If amount deposited is less than price then error message will be displayed and all deposited coin will be dispensed by the coin dispenser else the drink will be dispensed by the product dispenser.

DCA which is Digital Capability Assessment is usually conducted for the internal employees of TCS who are selected for the Ninja profile. If DCA is cleared successfully, then the candidates are offered Digital profile. That means the profile changes from Assistant System Engineer to System Engineer . This year i.e., in 2021, TCS conducted DCA for the candidates who have received offer letter but not joined TCS as an employee yet. The original DCA which is conducted for internal employees has a different pattern and is not discussed in this post. Rather this post is dedicated to the DCA conducted in March and April 2021 for 2021 recruits. The DCA was conducted on 19 th and 20 th March 2021. The test had two coding questions.
