Human-Computer Interaction: Channels, Models, and Interfaces

Lecture 8:

Input-Output Channels:

Input-Output channels in the context of human-computer interaction (HCI) refer to the means by which users interact with a computer system. Inputs are the actions or signals provided by the user to the system, while outputs are the responses or feedback provided by the system to the user. These channels serve as bridges between the user and the computer, facilitating communication and interaction.

Input via Senses:

Input via senses refers to the process of providing

Understanding TCP Three-Way Handshake and Application Layer Protocols

TCP THREE WAY HANDSHAKE: Hosts track each data segment within a session and exchange information

about what data is received using the information in the TCP header. TCP is a full-duplex protocol, where each connection represents two one-way communication streams or sessions. To establish the connection, the hosts perform a three-way handshake. Control bits in the TCP header indicate the progress and status of the connection.The three-way handshake:

  • Establishes that the destination device is present

C++ Functions and Arrays: A Comprehensive Guide

CIS-265 Test 1 Cheat Sheet


Chapter 6

Local variables lost their values between calls to the function in which they are defined because they are created in memory when the function begins execution and are destroyed when the function ends.


The difference between an argument and a parameter variable is that an argument is a value passed to a function and a parameter variable is a variable local to the function which receives the argument. The argument’s value is copied into the parameter variable.

Spiral Model vs. Waterfall Model: A Comparative Analysis

• The spiral model is a risk-driven process model generator for software projects.

• This Spiral model is a combination of iterative development process model and sequential linear development model.

• i.e. the waterfall model with a very high emphasis on risk analysis. It allows incremental releases of the product or incremental refinement through each iteration around the spiral.

Java Database Connectivity and JavaScript Objects

JDBC

JDBC stands for Java Database Connectivity, an API in Java that allows Java programs to connect and interact with a database. In other words, JDBC is the bridge between Java code and a database system. It is installed automatically with JDBC software. It provides classes and interfaces to connect or communicate Java applications with a database system.
