1. To improve system performance: Upgrading components like RAM or the CPU can facilitate faster processing speeds and enhance the overall efficiency of the computer.

2. To meet new software requirements: As software applications evolve, they often necessitate more powerful hardware to run efficiently, necessitating an upgrade.

1. Use a USB flash drive: Software can be installed via a USB drive that contains the installation files.

2. Download from the Internet: Users can download software directly from the web and install it on the computer.

1. Compatibility issues: The new version may not be compatible with older files or with other software in use.

2. Learning curve: Users may need time to familiarize themselves with new features and changes in the user interface, which can lead to temporary reductions in productivity.

1. Digital signal transfer: HDMI transmits data digitally, providing better picture quality and higher resolutions compared to analog VGA.

2. Prevent unauthorized installation of software: A standard user account can restrict the installation of potentially harmful software, safeguarding the system.

1. The clock speed of Intel Core i5 should be measured in GHz, not MHz (1.7 MHz is incorrect, it should be 1.7 GHz).

2. Windows 9 is listed, but this version does not exist; it should be Windows 8 or Windows 10.

3. The screen size of 1.56" is incorrect; it should likely be 15.6".

An app store is a digital platform where users can download and purchase applications for their devices. In this context, it is suggested to find an app that handles the file type or operation needed, facilitating access to necessary software that may not be pre-installed.

1. Protection against malware: Keeping a computer secure helps prevent infections from viruses and other malicious software, which can compromise data integrity.

2. Safeguarding personal information: A secure computer helps protect sensitive information from unauthorized access or data breaches.

1. Avoid using portable media: Reduce the risk of infection by not using USB drives or external storage devices that may be contaminated.

2. Exercise caution online: Do not download files from untrusted sources and avoid clicking on suspicious links in emails or websites.
