Abstract: The Microcontroller: Frequently Asked Questions offers the These high-speed and secure processors are pin and code
There will be address, control, and data buses. But micro controller is a computer on a chip which has memory,input,ouput on the chip itself. So,micro processor can perform only few functions but micro controller can perform so many functions. When a processor or DMA-enabled device needs to read or write to a memory location, it specifies that memory location on the address bus the value to be read or written is sent on the data bus.
The width of the address bus determines the amount of memory a system can address. Other connections are the address bus and control signals. The width and clock rate of the data bus determine its data rate the number of bytes per second it can carry , which is one of the main factors determining the processing power of a computer CONTROL BUS:-The control bus or command bus transports orders and synchonisation signals coming from thecontrol unit and travelling to all other hardware components.
It is a bidirectional bus, as it also transmits response signals from the hardware. As a nibble contains 4 bits. The size of a byte is typically hardware dependent, but the modern de facto standard is 8 bits, as this is a convenient power of 2. WORD:- The most common microprocessors used in personal computers for instance, the Intel Pentiums and AMD Athlons are an example of this; their IA architecture is an extension of the original Intel design which had a word size of 16 bits.
Typically, this specialized storage is not considered part of the normal memory range for the machine.
What is interrupt? What is cache memory? The cache memory is only in RAM. What is a compiler? The Execution time is less compared to Interpreter.
Which processor structure is pipelined? What is flag? What is stack? Can ROM be used as stack? It is also known as shadow RAM.
Java interview questions and answers 1. What is garbage collection? What is the process that is responsible for doing that in java? Garbage collector is responsible for this process 2. What kind of thread is the Garbage collector thread?
What is a daemon thread? The JVM can exit when there are daemon thread by killing them abruptly. How will you invoke any external process in Java? What is the finalize method do? What is mutable object and immutable object? What is the basic difference between string and stringbuffer object?
StringBuffer is a mutable object. What is the purpose of Void class? What is reflection? What is the base class for Error and Exception? What is the byte range?
What is the implementation of destroy method in java.. What is a package? Packages provides wide namespace ability. What are the approaches that you will follow for making a program very efficient? What is a DatabaseMetaData?
What is Locale? How will you load a specific locale? What is JIT and its use? Is JVM a compiler or an interpreter? What is the purpose of assert keyword used in JDK1. It effectively replaces the if block and automatically throws the AssertionError on failure.
This keyword should be used for the critical arguments. Meaning, without that the method does nothing. How will you get the platform dependent values like line separator, path separator, etc.
What is skeleton and stub? Skeleton is the server side representation. But that is no more in use… it is deprecated long before in JDK. What is the final keyword denotes?
What is the significance of ListIterator? What is the major difference between LinkedList and ArrayList? ArrayList are meant for random accessing. What is nested class? What is inner class? What is composition? What is aggregation? If you expose all the methods of a composite class and route the method call to the composite method through its reference, then it is called aggregation.
What are the methods in Object? Can you instantiate the Math class? All the methods in this class are static. And the constructor is not public. What is singleton?
This falls in the creational pattern of the design pattern. There will be only one instance for that entire JVM. You can achieve this by having the private constructor in the class. For eg. What is DriverManager? What is Class. It returns the Class. Inq adds a question: Expain the reason for each keyword of public static void main String args J2EE interview questions and answers 1. What makes J2EE suitable for distributed multitier Applications?
Application logic is divided into components according to function, and the various application components that make up a J2EE application are installed on different machines depending on the tier in the multitier J2EE environment to which the application component belongs. The J2EE application parts are: What is J2EE? The J2EE platform consists of a set of services, application programming interfaces APIs , and protocols that provide the functionality for developing multitiered, web-based applications.
What are the components of J2EE application? Application clients and applets are client components. Java Servlet and JavaServer Pages technology components are web components. Enterprise JavaBeans components enterprise beans are business components. Resource adapter components provided by EIS and tool vendors. What do Enterprise JavaBeans components contain? All the business code is contained inside an Enterprise Bean which receives data from client programs, processes it if necessary , and sends it to the enterprise information system tier for storage.
An enterprise bean also retrieves data from storage, processes it if necessary , and sends it back to the client program. Is J2EE application only a web-based? A J2EE application can be web-based or non-web-based.
When user request, it can open an HTTP connection to establish communication with a servlet running in the web tier. They are written to manage the data flow between an application client or applet and components running on the J2EE server or between server components and a database.
JavaBeans components written for the J2EE platform have instance variables and get and set methods for accessing the data in the instance variables. JavaBeans components used in this way are typically simple in design and implementation, but should conform to the naming and design conventions outlined in the JavaBeans component architecture. Is HTML page a web component? Static HTML pages and applets are bundled with web components during application assembly, but are not considered web components by the J2EE specification.
Even the server-side utility classes are not considered web components, either. What can be considered as a web component? Servlets are Java programming language classes that dynamically process requests and construct responses. JSP pages are text-based documents that execute as servlets but allow a more natural approach to creating static content. What is the container? Before a Web, enterprise bean, or application client component can be executed, it must be assembled into a J2EE application and deployed into its container.
What are container services? Containers provide components with services such as lifecycle management, security, deployment, and threading.
What is the web container? Web components and their container run on the J2EE server. Enterprise beans and their container run on the J2EE server. What is Applet container? Consists of a Web browser and Java Plugin running on the client together.
How do we package J2EE components? A J2EE application is composed of one or more enterprise bean,Web, or application client component modules. The final enterprise solution can use one J2EE application or be made up of two or more J2EE applications, depending on design requirements.
A J2EE application and each of its modules has its own deployment descriptor. A deployment descriptor is an XML document with an. What is a thin client? What are types of J2EE clients? What is deployment descriptor? For example, an enterprise bean module deployment descriptor declares transaction attributes and security authorizations for an enterprise bean.
Because deployment descriptor information is declarative, it can be changed without modifying the bean source code. At run time, the J2EE server reads the deployment descriptor and acts upon the component accordingly. What is the EAR file? JTA provides a standard 8.
Therefore, JTA is a high level transaction interface that your application uses to control transaction. What is JAXP? It provides standard services to determine the type of an arbitrary piece of data, encapsulate access to it, discover the operations available on it, and create the appropriate JavaBeans component to perform those operations.
What is J2EE Connector? Each type of database or EIS has a different resource adapter.
A resource adapter is a software component that allows J2EE application components to access and interact with the underlying resource manager. Because a resource adapter is specific to its resource manager, there is typically a different resource adapter for each type of database or enterprise information system.
What is JAAP? It is a standard Pluggable Authentication Module PAM framework that extends the Java 2 platform security architecture to support user-based authorization.
