Study Notes
Purpose of Information in a Computer
- Enables processing, storing, retrieving, and communicating data efficiently.
- Supports various applications ranging from simple tasks to complex computations.
Distinction of Computers
- Computers differ from other devices through their programmability, enabling them to perform a wide range of tasks based on user-defined instructions.
Information Technology (IT)
- Encompasses the use of systems, software, and networks for storing, retrieving, and sending information.
- Involves various disciplines including computer science, telecommunications, and broadcasting.
Big Data & Big Data Analytics
- Main focus is on analyzing vast amounts of data to uncover patterns, correlations, and insights.
- Emphasizes improving business decision-making and predicting trends.
Purpose of an Information System (IS)
- Serves to collect, process, store, and distribute information to support decision-making and control within an organization.
Intelligent Software Technology
- Refers to Artificial Intelligence (AI) that learns from data and improves its performance over time.
Guidelines in Information Systems
- The part of an information system that consists of rules or guidelines is known as policies or procedures for effective software, hardware, and data use.
Computer's 'Brains'
- The Central Processing Unit (CPU) is considered the 'brains' of a computer where all decisions, computations, and input/output requests are managed.
Volatile Memory
- Random Access Memory (RAM) is classified as volatile memory, temporarily holding data being processed by the CPU.
Receiving Information
- Output devices, such as monitors and printers, enable users to receive information generated by computers.
Semi-Permanent Memory Storage
- Secondary storage devices (such as hard drives and SSDs) provide much larger, semi-permanent data capacity compared to main memory (RAM).
Arithmetic and Logical Operations
- The Arithmetic Logic Unit (ALU) within the CPU performs arithmetic and logical operations using the binary number system.
Storage of Programs and Systems
- The hard disk drive (HDD) or solid-state drive (SSD) stores the programs, operating system, and applications necessary for computer operation.
Non-Volatile Memory
- Read-Only Memory (ROM) is non-volatile, retaining data even when the computer is powered off, and is structured in bits and bytes.
Supplying Information to Computers
- Input devices, such as keyboards and mice, allow users to supply information to computers for processing.
Components of an Information System
- Includes hardware, software, data, procedures, and people for effective networking and internet connectivity.
