SDKAPI
SDK is a kit that offers tools, code samples, libraries, processes, guides or relevant documents for creating software applications on specific platforms.It is an interface that allows the software to interact with each other.
An SDK is a complete workshop that allows us to create beyond the scope of API.It can translate and transfer two different instruction sets for mutual understanding.
SDKs are the origin point of almost every program that we use.It comes in many sizes and shapes.
Sometimes, even copy-pasting needs an API.
SDK contains API sometimes.API has a somewhat different function in the World Wide Web. The Web API facilitates interaction between disparate systems, especially for specific cases.

Q #6) You want to access a file on a shared drive, but for some reason, you are unable to. What will you do?

Answer: Answer this question carefully. The interviewer wants to listen to your approach to solve the problem.

First, check if the system that is sharing the drive is turned on. If it is, you will check the other files that you have permission to access to see if the issue is with all the files. Check if you have permission i.e. the correct permissions to access that particular file.

If everything is okay and yet you are not able to access that file, then make sure your programs are working fine to copy that file on your local drive. Also, make sure that the file is not currently being used by someone else.

Q #7) What are the Pros and Cons of using Imaging Software?

imaging software

Answer:

Pros of Imaging software:

  • Imaging software creates a precisely duplicated content from one hard disk to another.
  • It simultaneously delivers hard drive images to one or many systems over the network.
  • If the utility has intimate knowledge of individual partitions of file systems, then it can resize them for many file systems.

Cons of Imaging software:

  • It lacks intimate knowledge of file systems and that results in copying of source hard disk into image block by block. This takes a long time for completing the work for large disks.
  • It offers little recovery from errors or its detection during the generation and deployment of the image.
  • The best imaging software is expensive and commercial.

Q #8) What do you know about Ghost Imaging?

Answer: Also known as Cloning, Ghost Imaging is a backup process driven by software. It copies the hard disk contents to another server in one compressed file or a set of files which is referred to as an image. When needed, it can also change a ghost image back to its original form. It is often used during the reinstallation of OS.

Ghost Imaging serves two main purposes:

  • To allow a system to be cloned onto others.
  • Or, to quickly restore a system.

It is often used for setting up blocks of Tablets, Notebooks or Servers quickly. It also enables transfer from one PC or disk to another.

Q #9) Tell us about Disk Partition. How many partitions can a hard drive have?

Answer: A disk partition is a defined space for storage on a hard drive. It helps in organizing data efficiently and effectively.

Commonly, users store applications and OS data on one partition and user data on another. In case of issues with Windows, the partition with OS can be formatted completely and then reinstalled without any effect on the data partition.

A disk may have up to four primary partitions but only one can be active or have three primary partitions and one extended partition. In the extended partition, you can create a bigger amount of logical partition.

Q #10) What do you know about BOOT.INI?

Answer: BOOT.INI is a Microsoft initialization file containing the boot options for Microsoft Windows NT, 2000 and XP. It is always found on the primary hard drive’s root directory i.e. the C drive.

It has two main sections:

  • The section with operating systems that contains boot entries, one or more, for each bootable program or OS that is installed on the computer.

Q #11) Can you manually edit the BOOT.INI file?

Answer: Yes. But before manually editing the BOOT.INI, make sure that you save a copy in case anything goes wrong. To edit the file, go to the control panel and then to the System option. Go to the advanced tab in the properties window.

There you will find the startup and recovery option, move to its Settings. Select the edit option for editing BOOT.INI. If there is a 3GB switch, remove it and add the PAE switch on the servers with over 4GB of the installed physical memory for booting the file. Save the file and then close it. Click on OK twice and exit the Control Panel.

Q #12) What is a Gateway pertaining to the network?

Network Gateway

Answer: A gateway is a hardware device like a Firewall, Server, Router, etc that acts as a gate between networks. It allows the data or traffic to flow across the networks. A gateway is a node itself on the edge of the network and protects the other nodes in a network.

Every data flows through the gateway node before coming in or going out of the network. A gateway can also translate data from the outside network into a protocol or a format that all the devices in the internal network understand.

Q #13) What is Cache Memory? What are its advantages?

Answer: Cache memory acts like a buffer between the CPU and RAM and is an extremely fast type of memory. For easy and quick access, the frequently requested instructions and data are stored in cache memory.

It comes with three different levels i.e. L1, L2, and L3. L1 is generally found in the processor chip. It is the smallest and the fastest of all for the CPU to read. It ranges from 8 to 64KB. The other two cache memories are larger than L1 but also takes longer to access.

Q #14) Tell us some advantages and disadvantages of Overclocking.

Answer: Overclocking is making the CPU run at a higher speed than the default by using the current motherboard settings.

AdvantagesDisadvantages
Overclocking delivers more performance for the same price.Overclocking makes manufacturer warranty on CPU void since it compromises the quality guarantees provided by them.
High-frequency clocking offers better gameplay experience had a faster response time. This, in turn, delivers better graphics and increased productivity.Overclocking increases the temperature of the CPU. So, if you aren’t investing in a better cooling system, the process will damage the processors.

Q #15) How are a Chipset, Processor, and Motherboard different from each other?

Answer:

Difference between Motherboard and Chipset:

The Motherboard holds all the components with the expansion cards and CPU plugged into it. It also carries the connection to the USB, PS/2 and all the other ports. It is the largest printed circuit board inside a computer.

While Chipset is a particular component set that is integrated directly into the motherboard and usually consists of northbridge chipset and southbridge chipset. Core system interconnections happen due to the former while the latter manages the connection between the other components.

Difference between Motherboard and Processor:

The main difference between the two is that the Motherboard lets memory, peripheral connectors, processor and such components to communicate with each other. While carrying the specific instructions for functions like performing logical, arithmetical and control operations is the job of the Processor.

Q #16) If you can’t see the display of your system, what could be the issue?

Answer:

Here are a few reasons for which you can’t see the display:

  • Monitor not working.
  • The system has not yet completely started.
