Study Notes
Types of Computer Systems
- A computer system is a combination of hardware and software.
- Different types of hardware formats include desktops, laptops, smartphones, tablets, servers, quantum computers, mainframes, and embedded systems.
Desktop Computers
- Also known as a tower, requiring external components like a monitor, keyboard, and mouse.
- Not portable; needs to be plugged in constantly.
- Generally more productive due to larger screen and full-size peripherals.
Laptops
- Portable with built-in monitor, keyboard, and mouse.
- Battery-powered, allowing use on the go.
- Often preferred for travel, while desktops are common in offices.
Smartphones
- Ultra-portable but limited by smaller screen size and lack of physical keyboard.
- Increasingly common as computers, but functionality may be restricted compared to other devices.
Tablets
- Larger screen than smartphones and often used for similar functions.
- Can sometimes be paired with keyboards and mice for enhanced usability.
Hybrid Devices
- Examples include iPad Pro with an attached keyboard.
- Folding smartphones can transform into a tablet experience.
Servers
- Powerful computers providing services to multiple users, typically managed by a team.
- Example usage: hosting applications, websites, and databases.
Quantum Computers
- Still in development; fundamentally different from traditional computers.
- Use qubits, which can represent both 0 and 1 simultaneously, allowing for advanced processing capabilities.
- Research indicates potential to solve complex problems unsolvable by classical computers.
Mainframes
- Large, powerful computers designed for high-volume processing tasks like banking and transaction management.
- Known for reliability and 24/7 operation due to built-in backups and maintenance teams.
- expensive, with some models costing over £100,000.
Embedded Systems
- Defined as computers embedded within larger systems, performing dedicated tasks.
- Example: Hot tubs have mini-computers controlling features such as jets and heating.
- Often simple and basic, focused on one function without general-purpose capabilities (e.g., cannot play games).
Internet of Things (IoT)
- Refers to the networking of embedded systems for greater communication and functionality.
- Examples of IoT in homes include smart appliances like toasters, microwaves, light bulbs, and their ability to communicate with users’ phones.
Additional Embedded Systems Examples
- Modern cars utilize numerous embedded systems for functions like navigation and automatic controls.
- Autopilot in airplanes serves as an embedded system focused solely on flight management.
