Study Notes
Information Systems
- Information System (IS) organizes the collection, organization, storage, and communication of data.
- Database (DB) refers to a large amount of related data adhering to specific static or dynamic restrictions.
System Units
- Mainframe computers serve large organizations for task-critical applications, enterprise resource planning, and transaction processing.
- Microcomputers (desktops) are small computers that use a microprocessor as the CPU, integrating memory and I/O on a single motherboard.
Types of Computers
- Laptops are portable computers designed for mobile use.
- Notebooks are smaller and lighter than laptops.
- Tablets and iPads are even smaller than notebooks and typically do not include a keyboard.
- iPods are compact devices without GSM capabilities.
- iPhones and mobile phones include a GSM card and provide communication functions.
- Devices like iPhones, iPads, and iPods run on Apple's iOS operating system.
- E-Readers allow users to read digital content such as eBooks and newspapers.
Memory Types
- Memory capacity is measured in Bytes and is categorized into permanent and non-permanent types.
- Permanent memories include ROM and storage devices (USB Flash, Hard Disk, CD-ROM, Floppy disk).
- Non-permanent memories consist of CPU registers, RAM, and Cache Memory.
RAM and Storage
- Random Access Memory (RAM) stores frequently used program instructions and enhances system performance.
- Modern RAM typically has a capacity of around 4 GB, with memory arranged in Bytes, each with an address system.
- A Byte consists of 8 bits, where each bit represents a binary value (0 or 1).
ROM and Cache Memory
- Read Only Memory (ROM) is essential for booting the computer and contains vital system operation instructions.
- Cache Memory serves as a faster intermediary storage between the CPU and RAM, typically around 256 KBytes in size, optimizing data retrieval speed.
Data Communication Components
- Data Bus (BUS), made of copper lines on the motherboard, connects the CPU to Cache, RAM, and other ports, facilitating data transfer among components.
