Three-tier architecture

A software architecture style that separates application logic from data storage, improving security, scalability, flexibility, and load balancing.

Two-tier architecture

An architecture style where the UI and application logic reside on the client-side and the data storage resides on the server-side. The business logic layer is absent.

One-tier architecture

Architecture with all application components running on a single machine (client or server).

Logic Layer

Acts as an intermediary between users and data, ensuring the correct data is accessed.

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
