Study Notes

Software Applications

Software applications are programs designed for specific tasks, like word processing or presentations.
Productivity software helps users complete tasks efficiently. It includes word processing software, spreadsheets, presentation software, and web browsers.
Collaboration software facilitates teamwork. It includes email clients, conferencing software, instant messaging, online workspaces, and document sharing.
Business software manages business functions. It includes database software, project management software, business-specific applications, and accounting software.
Utility software provides essential functions. It includes anti-malware and firewall software, compression utilities, and PDF readers.

Application Delivery Methods

Locally installed software is stored on the user's computer.
Locally network-hosted software is installed on a server and accessed on a local network.
Cloud-hosted software is stored on a remote server, and accessed through the internet.

Application Architecture

One-tier architecture: all application components run on one computer.
Two-tier architecture: application components are separated; the user interface communicates with the database layer on a server (client-server model).
Three-tier architecture: separates the application, business logic, and database layers on different systems (also a client-server model).

Software Licensing

Software licensing is a contractual agreement specifying how the software can be used.
Types of licenses: freeware, shareware, single use, group use, site license, concurrent license.
Licenses can restrict installation to a single user or across multiple computers.

Software Installation and Uninstallation

Software installation methods often involve installing the software from a disc or downloading from a website and running the .exe or .msi executable file.
Consider the operating system and hardware compatibility when installing software.
Software manufacturers provide installation and uninstallation instructions, and there are tools within the OS for managing and uninstalling applications or drivers.

Software Updates and Patches

Updates improve functionality or fix errors, whereas patches address specific bugs, so be sure to update software.
Security software and the operating system are the main areas that require regular updates.

Web Browsers

Web browsers are critical for accessing the internet and require configuration to ensure security.
Settings and configurations can be tailored to limit security risks from malware and intrusions.
Configurations include clearing browser cache and cookies, disabling scripts and pop-ups, configuring proxy settings, and recognizing secure sites.
Private browsing mode offers security enhancements by not storing browsing data.

Firewalls

Firewalls are either hardware or software protections that manage the traffic between private and public networks.
Network firewalls filter traffic between your network and the internet or public networks.
Host-based firewalls monitor a single computer’s network traffic.

Compression Software

Compression software reduces file size to allow for easier storage, transmission, or sharing.
Different compression software formats deal with different types and levels of information to compress as well as uncompress.

PDF Viewers and Creators

PDF viewers and creators are programs that display and sometimes edit files in PDF formats.
PDFs are frequently used for distributing documents
