Study Notes
Computer Types and Classification
- Objectives: Students will identify different computer types, understand their classification based on size and function, and develop a prototype technology.
Mother of Computer
- Ada Lovelace, Countess of Lovelace, was a mathematician and writer, known for her work with Charles Babbage's Analytical Engine.
- She's considered the "Mother of Computer" for her pioneering work.
Abacus
- The abacus is a simple calculating tool, with beads on rods.
First Computer (ENIAC)
- ENIAC (Electronic Numerical Integrator and Computer) was the first electronic, Turing-complete device used for ballistic trajectory calculations.
- It was built for the United States Army, and marked a significant step in computing history, as the first programmable computer in the U.S.
Different Types of Computers
Analog Computers
- Analog computing technology is on the decline.
- Analog computers process information using physical quantities like voltage or pressure.
- They perform calculations simultaneously, unlike digital computers.
Digital Computers
- Digital computers are prevalent today.
- Digital computers use binary code (bits 0 and 1) to represent data.
- This is analogous to "on" and "off" states.
Hybrid Computers
- Hybrid computers combine analog and digital features.
- Digital segments manage tasks, while analog parts perform processes through signal conversions.
Classification of Computers
Mainframe Computers
- Large organizations use mainframes for critical applications, like bulk data processing.
- They can host multiple operating systems and act as virtual machines, effectively replacing several small servers.
Mini Computers
- Minicomputers, also called mid-range systems or workstations, are intermediate in size and processing capacity between mainframes and microcomputers.
- They gained popularity during the 1960s, as smaller third-generation computing devices.
Servers
- Servers provide services to client devices in a network.
- They handle large storage and have powerful processors, allocating resources, memory, and time for clients.
- Their robust construction, with many hard drives and powerful processors, ensures reliability and stability.
Supercomputers
- Supercomputers handle highly intensive calculations—quantum physics, weather forecasting, and molecular theory are some examples.
- Their parallel processing ability and memory hierarchy provide great processing power for complex tasks.
- Supercomputers are often found in banks and government departments.
Microcomputers
- Microcomputers, or personal computers (PCs), have microprocessors.
- They are smaller and less costly than mainframes.
- They are well-suited for single-user tasks and are commonly used in offices, schools, and homes.
Examples of Microcomputers:
- Desktop computers
- Laptops
- Netbooks
- PDAs
- Tablets
- Wearable computers
Personal Computers:
Desktops
- Designed for use in a single location.
- Desktop computer parts are readily available at lower costs.
Laptops
- Designed for portability, similar to desktops.
- Operates on batteries or external charging adapters.
Netbooks
- An inexpensive, smaller variation of laptops.
- Netbooks have limited features for faster efficiency and lower cost.
Personal Digital Assistants (PDAs)
- Handheld computers that can be used as portable audio players and web browsers, often with touch screens, for easy data storage, using memory cards.
- Access to internet is usually with Bluetooth or Wi-Fi.
Tablets
- Mobile computers using touch screens.
- Commonly used for tasks where input is via touchscreen.
- Often includes onscreen keyboards or external stylus/digital pens.
Wearable Computers
- Designed for wearing on the body.
- Useful in health, behavioral modeling, and military applications.
- Often run in the background, without user intervention.
Activity (Prototype Technology)
- Create a prototype of a technology useful in 5 years.
- Include the name, features, and usefulness.
Real-life Application Questions
- What is the importance of computers in your life as a student?
- Why is learning about different computer types important?
