1.10 - CompTIA A+ Core 2

32-bit application

An application that runs on a 32-bit (x86), and a 64-bit (x64) processor.

64-bit application

An application that can only run on a 64-bit (x64) processor.

RAM

Random Access Memory - a temporary, volatile location for computer applications, data, and instructions.

RAM requirements

Specifications that dictate how much RAM is required to run an application. Critical specification - without enough RAM, the application may perform poorly, or not at all. Typically listed above and beyond the OS requirements.

\Program Files (x86)

Windows folder used to store 32-bit applications.

\Program Files

Windows folder used to store 64-bit applications.

CPU

The “brain” of the computer that executes instructions from applications and the operating system.

CPU requirements

Specifications that outline the minimum and recommended processing power needed for applications to function correctly. This includes factors such as clock speed, core count, and architecture.

Integrated graphics card

A graphics card where the CPU and GPU are on the same chip, utilizing system memory for graphics.

Dedicated graphics card (GPU)

A discrete graphics card providing VRAM and higher graphics processing power for advanced applications like gaming and video editing.

Storage requirements

The amount of drive space that applications require for installation and use.

External hardware tokens

Physical tokens, often USB devices, needed to unlock/use applications, ensuring operation only when the token is connected.

Application to OS compatibility

The requirement for applications to match the operating system they are being installed onto.

Image deployment

A method allowing the installation of an entire OS with desired applications on multiple machines using OS images. Useful for companies.

Physical media installation

Installing applications from a physical flash drive (e.g., CD, DVD, USB). Increasingly rare method, and commonly used for when a machine cannot connect to the Internet (e.g., data centers).

ISO files

Used to install operating systems. Disk image that contains operating system files organized into folders within its own filesystem. Mounted into your main OS as a separate drive (i.e., separate drive letter).

Downloadable package

Applications installed directly from the Internet - install from the developer website, or from a centralized app store for better security.

Device impact for new applications

Refers to issues seen after an upgrade - such as slowdowns, non-functioning applications, and deleted files

Network impact for new applications

Access to internal services - rights and permissions to file shares.

Operation impact for new applications

Time-sensitive application installation - updated applications may also require workflow changes.

Business considerations for new applications

Critical processes are sensitive to downtime and outages. Applications have the same rights and permissions as the user who is logged in. Unknown/untested applications can therefore cause significant issues.
