Hardware and Networking Interview Questions with Answers How do they work? Administrative shares are usually created automatically for the root of each drive letter. They do not display in the network browse list. Name of seven layers in Open System Interconnection model. The address resolution protocol ARP is used to associate the 32 bit IP address with the 48 bit physical address, used by a host or a router to find the physical address of another host on its network by sending a ARP uery packet that includes the IP address of the receiver. The reverse address resolution protocol RARP allows a host to discover its Internet address when it knows only its physical address.
Hyper-threaded processors have a duplicate set of registers, small spaces of high-speed memory storage used to hold the data that is currently needed to execute a thread.
When a CPU core is delayed, waiting for data to be retrieved from another place in memory, it can use these duplicate registers to spend the spare computation cycles executing a different thread.
The second set of registers will be pre-loaded with the data needed to execute the second thread, so the CPU core can begin work immediately.
While small and light on energy use, Atom processors can handle the most common tasks, such as email and instant messaging. Which is the processor suitable from Intel family of processors for Server and Workstation?
Socket is developed by AMD. It supports a maximum of how many bits of computing? What are the the different processors of AMD is suitable for this socket? Which type of socket is needed to connect a dual core processor of Intel?
Socket LGA What is Heat Sink? What is its use? If it is not in the system what will happen?
A heat sink is a component used to lower the temperature of a device. It is most commonly there on the microprocessor. If it is not properly fixed the system, the system will shutdown automatically to prevent further damage to the processor.
A CPU fan should be placed in system. To make the system cool and more functioning. Upgrading a microprocessor is just physically replacing a processor with a new one. We also have to make sure that the motherboard has the internal logic to support the processor.
What is the use of Conventional memory in the system? The size of conventional memory is KB. It is also called DOS memory or Base memory. The main memory in a computer is called Random Access Memory. It is also known as RAM. This is the part of the computer that stores operating system software, software applications and other information for the central processing unit CPU.
What is Cache memory? What is the advantage if a processor with more cache memory you are using? Cache memory is the memory area between RAM and Processor. If cache memory increases the speed of the system will also improved. What are the different types of RAM? SRAM is used in devices that require the fastest possible data access without requiring a high capacity.
Some examples are CPU caches and buses, hard drive and router buffers and printers. Capacitors constantly leak electricity, which requires the memory controller to refresh the DRAM several times a second to maintain the data. What are the different DRAM types? DDR 2 incorporates several technological upgrades to computer system memory, as well as an enhanced data rate. It operates at a lower voltage than DDR-I as well: Video adapter or video system uses VRAM.
VRAM is dual ported. It is costly. It is a less expensive approach to graphics functions. Most commonly all low cost graphics cards are using it. It is a smaller version of a dual in-line memory module DIMM. It is the type of the memory module can be used in laptop. Which is the memory packaging suitable for a sub-note book system? Micro DIMM. EPP is for non-printer peripherals. ECP is for printers and scanners. What is over clocking? Over clocking is the process of forcing a computer component to run at a higher clock rate.
What is memory bank? Sets of physical memory modules is referred to as memory banks. A memory bank serves as a repository for data, allowing data to be easily entered and retrieved. What is Upgrading the memory? Adding a memory module to the existing bank on the available slot or replacing the previous one with the increased memory size is also called upgrading memory. This will surely increase the performance of the computer. What is BIOS beep code? What it does mean?
BIOS beep codes are the signs of different issues of the computer. The beep code may vary depends on the manufacture of BIOS. For example in case of Award BIOS the beep code will be, 1 long beep- shows memory problem 1 long beep and 2 short beeps- failure of DRAM parity 1 log beep and 3 short beeps- signifies Video error Continuous beep- signifies failure in memory or Video memory.
What are Solid State Drive means? A solid-state drive SSD , sometimes called a solid-state disk or electronic disk, is a data storage device that uses solid-state memory to store data.
SSDs use microchips which retain data in non-volatile memory chips and contain no moving parts. Compared to electromechanical HDDs, SSDs are typically less susceptible to physical shock, are silent, have lower access time and latency, but are more expensive per gigabyte GB.
What is SIMM? Is it is using now? Acronym for Single In line Memory Module, a small circuit board that can hold a group of memory chips. RAM chips. On PCs, the ninth chip is often used for parity error checking. Unlike memory chips, SIMMs are measured in bytes rather than bits.
Now a days this memory module is not used. Why do we call motherboard a motherboard? Motherboard is the basic integrated board of the computer on which all other components are connected.
It is easier to locate the related classes. Now, their sum 30 is treated as the string and concatenated with the string Javatpoint. Therefore, the output will be 30Javatpoint. In the second case, the string Javatpoint is concatenated with 10 to be the string Javatpoint10 which will then be concatenated with 20 to be Javatpoint In the second case, The numbers 10 and 20 will be multiplied first to be because the precedence of the multiplication is higher than addition.
The result will be treated as the string and concatenated with the string Javatpointto produce the output as Javatpoint However, they have been categorized in many sections such as constructor interview questions, static interview questions, Inheritance Interview questions, Abstraction interview question, Polymorphism interview questions, etc. It is a programming paradigm based on objects having data and methods defined in the class to which it belongs.
Object-oriented paradigm aims to incorporate the advantages of modularity and reusability. Objects are the instances of classes which interacts with one another to design applications and programs. There are the following features of the object-oriented paradigm.
Follows the bottom-up approach in program design. Focus on data with methods to operate upon the object's data Includes the concept like Encapsulation and abstraction which hides the complexities from the user and show only functionality. Implements the real-time approach like inheritance, abstraction, etc.
The Object is the real-time entity having some state and behavior. In Java, Object is an instance of the class having the instance variables as the state of the object and the methods as the behavior of the object. The object of a class can be created by using the new keyword. There are the following basic differences between the object-oriented language and object-based language. Object-oriented languages follow all the concepts of OOPs whereas, the object-based language doesn't follow all the concepts of OOPs like inheritance and polymorphism.
All object references are initialized to null in Java. The constructor can be defined as the special type of method that is used to initialize the state of an object. It is invoked when the class is instantiated, and the memory is allocated for the object. Every time, an object is created using the new keyword, the default constructor of the class is called. The name of the constructor must be similar to the class name.
The constructor must not have an explicit return type. Based on the parameters passed in the constructors, there are two types of constructors in Java.
Default Constructor: default constructor is the one which does not accept any value. The default constructor is mainly used to initialize the instance variable with the default values. It can also be used for performing some useful task on object creation.
A default constructor is invoked implicitly by the compiler if there is no constructor defined in the class. You have to be very careful on how you answer this question because your answer here sets the tone for the rest of the interview.
This question is mostly asked as an icebreaker but if you did not prepare for it, it becomes a real problem. The right approach to this is to discuss your key strengths and how they relate to the job. Talk about a few of your accomplishments. Talk about your current employer and then tell them how you see yourself fitting into a position at their company.
Or what are your career goals. It is crucial that you discuss your objectives and how you intend to achieve them. For instance: I would like to be the best in my department or I would love to be the person my colleagues can rely on. I also feel I would be skilled and experienced enough to handle whatever responsibilities might come my way.
This is a very common question that is asked in almost every interview. I love this question because it gives you the opportunity to sell yourself. Discuss what makes you standout from the crowd and show them how you can help advance their company. Remember to be specific.
This is where all the company research you have done comes into play. You should have an idea as to why the company is hiring or looking to hire someone for that position. What problem do they have that they are looking for people to help them solve. And once you can establish this, you are to show them how you can solve this problem for them. DO: a. Highlight the qualities that make you the most qualified for the position, present yourself as the candidate that solves their problem b.
Let them know that you already know certain things about the company and their general practice because you have researched the firm and are prepared. Tell a success story that emphasizes your qualities and how they helped solve a problem similar to theirs. DO NOT: a. When you are things like we already have lots of qualified candidates do not get discouraged.
If they already have the right person for the job, they would not bother looking for someone to hire b.
This is your chance to shine, do not ruin it by being too modest, but do not be arrogant c. Do not generalize things, it does not help d.
Your response should be geared towards why you are the perfect fit for the job and not why you want the job. The reason why you are asked this question is to hear what you consider difficult and how you approached the situation. Select a difficult work situation, which was not caused by you and can be explained in a few sentences. You can then show yourself in a positive light by explaining how you handled the situation. This could be a very simple question if you are prepared for it.
You just have to talk about the strengths that you know would be of value to the company. Make the most of this question. This question gives you the control to guide the interview to where you want it so take advantage. Emphasize the strengths you have that are crucial to the position c.
