How To Increase Transfer Rate Of An Hard Disk?

Answer»

See if any among these helps to increase HARD disk transfer rate...

  • Try using RAID setup
  • In Device MANAGER under ATA/ATAPI Controllers VERIFY if the hard disk is running in UDMA mode.
  • Update motherboard chipset drivers
  • Under Properties of the drive, Hardware Tab -> Properties of the hard disk:

Explain What Is The Difference Between Process And Thread With Real Time Examples?

Answer»
  1. Threads share the address space of the process that created it; processes have their own address.
  2. Threads have direct access to the data segment of its process; processes have their own COPY of the data segment of the parent process.
  3. Threads can DIRECTLY communicate with other threads of its process; processes must use interprocess communication to communicate with sibling processes.
  4. Threads have almost no overhead; processes have considerable overhead.
  5. New threads are easily created; new processes require DUPLICATION of the parent process.
  6. Threads can exercise considerable control over threads of the same process; processes can only exercise control over child processes.
  7. Changes to the main thread (cancellation, priority change, etc.) may AFFECT the BEHAVIOR of the other threads of the process; changes to the parent process does not affect child processes.

3.

Define Rom Image And Explain Each Section Of A Rom Image In An Exemplary System?

Answer»

A ROM image captures the data from a read-only memory chip, such as HARDWARE FIRMWARE, video and arcade GAME boards, ETC. It is often used for EMULATION.

How To Delete A Entire Linked List?

Answer»

You delete a linked list by iterating through the list and deleting the nodes one by one.

  • Begin at the head
  • GET ADDRESS of first NODE
  • Get address of next node
  • Delete first node
  • Do not to access next of the current node after deleting the current node.
  • Move next node to first node
  • Repeat

If the list is empty, the head pointer will be NULL.

Explain How To Calculate Response Time In Client-server Technology?

Answer»

This can be done by measureing the TIME taken by the FIRST byte to reach the client (TTFB) and the time taken by the last byte of the response to reach the client (TTLB) by USING various NETWORK bandwidths between the client and the server.

Do You Know Hows Do Electrons Travel Through A Lightning Bolt?

Answer»

GENERALLY, lightning is negatively CHARGED. During THUNDERSTORMS. The Earths is recharged and its surface becomes GOOD conductor of electricity. The EARTH is charged negatively and the atmosphere is charged positively. Electrons flow upwards from the entire surface of the Earth. Thunderstorms help transfer the negative charges back to Earth.

What Is Race Around Condition?

Answer»

A race AROUND condition is a fault in the process or a system where the output or the result of the process is critically and UNEXPECTEDLY DEPENDENT on the timing of other events. Race condition ESPECIALLY occurs in multithreaded or in DISTRIBUTED systems.

Explain What Are Mutants And Explain Mutation Testing?

Answer»

A mutated PROGRAM is CALLED Mutant and Mutation testing is BASED up on seeding the IMPLEMENTATION with a Fault by applying mutation Operator and determining whether Testing Identify this fault is called Mutation testing

Tell Me Why Constructors Does Not Supports Visual Functions?

Answer»

Constructor does not support virtual functions because we need an object to invoke a virtual method in the first place and more over constructors are used to initializing objects,which is a static type.Virtual functions are invoked on the dynamic type of the object,hence the object MAY not be properly INITIALIZED when a constructor call is made.Since the DERIVED part of the object would not be initialized during the execution of base CLASS constructor,hence calling any virtual method from base class constructor does not work well.

What Is Multithreading?

Answer»

MULTITHREADING is the ability of a PROGRAM or an operating system process to manage its use by more than one user at a TIME and to even manage multiple requests by the same user without having to have multiple copies of the programming running in the computer. Central processing units have hardware support to efficiently execute multiple threads. These are distinguished from multiprocessing systems (such as multi-core systems) in that the threads have to share the resources of a single core: the computing units, the CPU caches and the translation lookaside buffer (TLB).
