Study Notes

ICT in Industry

e-commerce involves services like transaction processing, documentation, presentations, inventory management, and gathering product information.
ICT in industry refers to businesses and organizations involved in software, computing, telecommunications equipment, consumer electronics, and related services.
The purpose of ICT education is to equip students with information and communication skills for using modern technology in various professional fields.
e-commerce refers to business transactions happening online.

ICT Defined

ICT (Information and Communication Technology) encompasses modern communication methods and technologies for searching, collecting, storing, processing, and disseminating information.
ICT is not just about computers; it encompasses a broad range of technologies.

ICT Standards

Standards in ICT refer to approved definitions or formats recognized by organizations or established as industry de facto standards.
Standards can be developed through four methods.
A de facto standard emerges when a single vendor dominates the market with its product.
Government doesn't use electronic communication devices and the internet to provide public services.
Software standards are controlled by both private and public/non-profit organizations.

Computer Models and Hardware

A computer model simulates the functions of a real system.
Open standards aim for interoperability, universality, and accessibility.
Purpose of hardware selection: consider factors like single vs. multi-user, instructional use, lab work, reusability, user technical skill, and infection control concerns.
Ad hoc method for developing standards involves a group of interested individuals and organizations agreeing on a specification.

Computer Types and Software

A computer is an electronic machine that performs input, processing, storing, and output operations based on instructions for specific tasks.
A desktop is designed for use in a single location and is commonly used at home and in the workplace.
A workstation is a powerful, single-user computer with a high-performance microprocessor and high-quality monitor.
Personal Computer Assistants (PCAs) are handheld computers, often known as palmtops, with a touch screen and memory card for data storage. (Note: PCAs are not the same as a handheld computer - they are a specific type of device)
Specialist application software is designed to perform a single, very specific task.
System software and application software are the two main categories of software.
Hardware are the physical components; software comprises the instructions that tell a computer how to perform tasks.
System software and application software are the two main categories of software.

System Software and User Interface

GUI (Graphical User Interface) elements include icons, menus, windows, and pointers; the command line is not part of a GUI.
BIOS (Basic Input/Output System) is a firmware program that initializes and tests hardware components upon startup.
Utility software helps monitor and configure settings for the computer system, operating system, or application software.
Icons are small images representing commands, files, or windows.
An operating system does not translate text from one language to another.
The kernel of an operating system manages memory, schedules tasks, and handles interrupts.

Operating System Startup and File Extensions

The correct order of operating system startup is:
- Turn on the computer
- Loading BIOS
- Loading the OS kernel into memory
- The operating system itself starts.
File extensions indicate file types:
- .com: Executable command MS-DOS
- .txt: Text file
- .xls: Microsoft Excel table
- .wav: Audio file

Software Types

Operating System examples include: Linux, DOS, and Microsoft Windows.
Application examples include: MS Word, and Macros.
Microsoft Windows and Mac OS are examples of system software.
Microsoft Office is an example of an integrated package.

Databases and Data Analysis

A relational database consists of a collection of tables.
The schema represents the logical design of a database; the instance is a snapshot of the data at a specific time.
Relational algebra allows users to retrieve information from a database using commands, and uses relational operators like select, project, union, intersect, difference, cartesian product.
Schema diagram visually represents the schema of a database, highlighting relationships between tables, attributes, and keys.
A primary key uniquely identifies a record within a table; foreign keys relate tables to one another (also are attributes in another, referring relation)
A super key uniquely identifies a record; a candidate key is a subset of a super key that is also a super key.
Key is a property of an entire relation; values refer to specific data entries.
Distinct returns a set of unique column values from a table.
Where clause filters rows based on a condition; from specifies the table to retrieve data from.
Select clause lists the attributes to include in the query results.

Spreadsheet Software

Column Chart is suitable for comparing values across categories.
A cell is the intersection of a column and row on a worksheet.
COUNT function counts the number of numeric entries in a range.
Excel is used for statistical calculations, preparing tables, and creating graphs.
Filtering displays data based on specified criteria.
A, B, C represent column labels in Excel.
1, 2, 3 represent row labels in Excel.
IF function checks whether a condition is true or false.
Functions in Excel start with an equal sign (=).
B1:E5 denotes a range of cells from B1 to E5.
Line Chart is suitable for showcasing trends over time.
Pie Chart is suitable for comparing parts of a whole.
Logical operators include > (greater than), < (less than), = (equal to).
Sorting arranges data in a column in a specific sequence.
Auto Fill completes a series of data based on patterns.
Chart Wizard helps create charts.

Key Concepts

Indivisible describes something that cannot be divided into separate parts.
A database is a collection of electronically stored data organized as records in tables.
