Study Notes
Introduction to Computer Science
- A computer represents information as bit patterns.
- Information can be in the form of numbers, video, or messages.
Boolean Operations
- Boolean operations involve the manipulation of true and false values.
- AND operation produces a true output when both components are true.
- OR operation produces a true output when at least one component is true.
Project Management
- Challenges in large projects include effort-intensive, high cost, technical know-how, and changing user needs.
- Software application development is successful when it is usable, useful, and used.
Data Structures
- A queue is a data structure where elements are added and deleted from the same end.
- A set of rules governing data transmission over a network is called a protocol.
Computer Systems
- A program that controls the execution of application programs and acts as an interface between the user and computer hardware is called an Operating System.
- A network that spans local governments or from city to city is known as a Metropolitan Area Network (MAN).
- A network that covers a small area, usually within a diameter of a few kilometers, is called a Local Area Network (LAN).
Networking
- A device that connects two or more smaller networks to form a bigger one is called a router.
- A device that allows user to access web pages on the internet is called a web browser.
- The internet is a network that is designed in a public domain and can be used by anyone without signing any license agreement.
Data Storage
- A storage place in the computer where data and information are kept is called computer memory.
- A scheme for organizing data in the memory of a computer is called a data structure.
Database Systems
- A database system consists of a Database (DB) and a Database Management System (DBMS).
- A field in a database that must always have a unique record is called a primary key.
- Queries are ways of searching for and compiling data from one or more tables.
Operating System
- The operating system is divided into two parts: Shell and Kernel.
- The Shell part of the operating system handles the communication between the user and the operating system.
- The Kernel part of the operating system performs the very basic functions required by the computer installation.
Computer Security
- A condition in which two or more processes are blocked from progressing is called a deadlock.
- A device that connects two heterogeneous networks together is called a bridge.
Computer Fundamentals
- Hardware devices that accept data, process data, and produce information are called computers.
- Each machine on a network must have a unique address for the internet, called an Internet Protocol Address (IP Address).
- The acronym HTML stands for Hyper-Text Markup Language.
