Dear Sir or Madam,

I am writing to express my dissatisfaction with my brand new headphone which malfunctioned when using. It was not good as I expected.

I purchased a new Airpod wireless headphone from online Shopee Stores on 29 October for $159. The piece is on a year warranty. It was delivered to my residence on 5 November.

Unfortunately, This headphone does not function at all and I noticed this problem as soon as I unpacked it from box. A pair of headphones only play audio out of one ear (only right side is working). Then suddenly both sides work but when I go a little bit back my left side isn't working.

Since the piece is on warranty, I'd like to request a replacement product. I hope this matter will be resolved at the end of this week. I highly appreciate it if you could reply to me in your earliest convenience.

Yours faithfully, Sang

I will share how to install the photoshop which is used for editing images, retouching photos. So let's start, we have 6 steps to install the photoshop. Firstly, you need to have a installer version of the photoshop or you can download form the internet. Secondly, decompression the installer version into any folder. Thirdly, run file installer.exe by double click on its icon.

After, choose the destination folder. Then, follow the onscreen instructions to install this program. The program is installed automatically. Finally, after installing the photoshop, you need to reset your PC. In addition, there is one small note if you don't want to do all this step again. When choosing the destination folder, make sure that folder is enough space to save data of your photos because after decompression it can take up a lot of space on your disk.

This is an incident report by Sang, a support technician. At 14:30, May 29th; a customer named Mary Jane called about an incident with her laptop. She had a Dell Inspiron running Windows Vista with 2GB of RAM. The customer reported that she could not install video editor program. The screen displayed the error message: "missing DLL files" without any error code. The customer has downloaded the missing DLL files from the internet but it seems to have no effect. I think she might have an installation error. If it is the case, she should run system file checker to fix this issue. Or that program is not compatible with current OS of her laptop. I suggest upgrading OS to the latest version. Since I can't solve the customer's problem right away, I have escalated to tier 2.

There are a lot of solutions for data storage and backup such as SSD, HDD, USB,... and cloud computing seems to be the most favorite and popular choice of many users and enterprises nowadays. Its special features include data security, data recovery, automatic updates, automatic sync,... It have some advantages. First, It is cheaper than any on-premise technology. Now, users do not need to store data in disks anymore as the cloud offers enormous storage space, which helps to save a lot of money on purchasing and maintaining equipment. Second, cloud computing allows mobile access to data, in any corner of the world as long as they stay connected to the Internet. Beside, this technology still remains some disadvantages. First, cloud computing systems are Internet-based, which means access is fully dependent on Internet connection. Another bad point is security risk. Uploading your data to the cloud means that all your information is shared to a third-party service provider and hackers might access this information. To sum up, I still prefer cloud computing for its convenience and easy use despite some disadvantages.

There are six steps to process the data. First, That is Data collection. You gather the raw data which you want to process. Then, you create categories to organize the data into relevant group, this is Data sorting. Next step, that is called Data coding, you can arrange and systemize the data. After, you enter the data to a system, we call that is data entry. Continue to Data validation, you clean the data and double-check for faults and inconsistencies. Finally, that is data tabulation, you arrange the data into table format so that it can be analyzed. All the steps is important, but I think Data collection is the most important, because it is the first step and take more time and it is difficult. There are six steps, you can follow to process the data.

One of the software I am impressed most is Adobe Photoshop CC is defined as a graphic editing software. It was developed and released by Adobe Systems in 1988. It has two main outstanding features. First, it provides professional photography tools to enhance pictures, transform them into amazing works of art. Second, it offers unique patterns, effects, advanced brushes to create and customize digital masterpieces.
Its benefits include Logo designing, creative art, blog images and many other professional things. However, it cannot be denied that the software also has some shortcomings, It includes many different tools, so it time-consuming to learn how to use each correctly. Although Adobe Photoshop CC has some limitations, it is worthy to experience.

The future of artificial brain implants holds promise for even more developed and accessible applications.
