A+ Core 2 Certification Cram Notes : Operating Systems

1.7 Apply application installation and configuration concepts

1. OS requirements for applications:

Application to OS compatibility: Applications are designed to work with specific operating systems. Compatibility of an application with the OS is important to ensure that the application runs smoothly and efficiently. Compatibility issues can cause the application to crash or not function at all.

32-bit vs. 64-bit OS: Some applications require a 64-bit operating system to run. A 64-bit OS can handle larger amounts of RAM and can provide better performance. However, not all applications are compatible with a 64-bit OS and may require a 32-bit OS to run.

2. Distribution methods:

Physical media vs. downloadable: Applications can be distributed through physical media such as CDs, DVDs, or USB drives. Alternatively, applications can be downloaded from the internet. Downloadable applications are convenient but may require a stable internet connection.

ISO mountable: Some applications are distributed as ISO files which can be mounted as a virtual drive. This method is convenient and avoids the need for physical media.

3. Other considerations for new applications:

Impact to device: Installing a new application can have an impact on the device's performance. It is important to check the system requirements for the application and ensure that the device meets them.

Impact to network: Downloading and installing large applications can consume network resources and affect network performance. It is important to plan for this and schedule installations during off-peak hours.

Impact to operation: New applications can affect the operation of existing applications or the OS. It is important to test new applications in a non-production environment before deploying them.

Impact to business: Installing new applications can have a significant impact on the business. It is important to evaluate the benefits and risks of the application and ensure that it aligns with the business goals and objectives.

1.8 Explain common OS types and their purposes

Workstation OSs

1. Windows: Windows OS is a popular and widely used OS for personal computers and laptops. It is user-friendly and supports a wide range of hardware and software.

2. Linux: Linux is an open-source operating system that is free to use and highly customizable. It is popular among developers and is commonly used in servers and workstations.

3. macOS: macOS is the operating system for Apple's Macintosh computers. It is designed specifically for Apple hardware and offers a user-friendly interface and seamless integration with other Apple products.

4. Chrome OS: Chrome OS is a lightweight, cloud-based operating system designed by Google. It is used primarily on Chromebook laptops and is optimized for web-based applications.

Cell phone/tablet OSs

1. iPadOS: iPadOS is Apple's operating system for its iPad tablets. It is based on iOS but includes additional features and optimizations for larger screens.

2. iOS: iOS is Apple's operating system for its iPhone smartphones. It is known for its user-friendly interface, app store, and tight integration with other Apple products.

3. Android: Android is an open-source mobile operating system developed by Google. It is used by a wide range of smartphones and tablets and offers customization options for both users and manufacturers.
