Dependency / Package Manager

npm

npm is nodejs package manager. It therefore targets nodejs environments, which usually means server-side nodejs projects or command-line projects (bower itself is a npm package). If you are going to do anything with nodejs, then you are going to use npm.

bower

bower is a package manager that aims at (front-end) web projects. You need npm and nodejs to install bower and to execute it, though bower packages are not meant specifically for nodejs, but rather for the "browser" environment.

composer

composer is a dependency manager that targets php projects. If you are doing something with symfony (or plain old php), this is likely the way to go

Terminology

Real-time processing

Real-Time Processing involves continuous input, process, and output of data. Hence, it processes in a short period of time.

Batch processing

Batch processing is the processing of transactions in a group or batch. No user interaction is required once batch processing is underway.

Command Line Interface (CUI)

Short for character user interface or command-line user interface, CUI is a way for users to interact with computer programs. It works by allowing the user (client) to issue commands as one or more lines of text (referred to as command lines) to a program. Good examples CUIs are MS-DOS and the Windows Command Prompt.

Graphical User Interface (GUI)

GUI is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based user interfaces

Archive

An archive is a collection of data moved to a repository for backup, to keep separate for compliance reasons or for moving off primary storage media. It can include a simple list of files or files organized under a directory or catalog structure (depending on how a particular program supports archiving).

Housekeep

When referring to computers, housekeeping is a term used to describe the optimization of a hard drive. Housekeeping commonly involves removing old or unused files and programs, backing up data, or running disk utilities such as a ScanDisk, Defrag, or an antivirus scan. Housekeeping keeps the computer organized, running properly, and should be performed at least once a year.
