Study Notes
Computing Basics - Chapter 2: Basic Computer Configuration
- Topics: Basic Operations, Computer Components, Computer Categories
Computing Terminology
- Data: Anything in a form suitable for use with a computer.
- Information: Processed data.
- Program: Computer instructions.
Types of Computers
- Analog Computer: Processes analog data, continuous and non-discrete. Data includes temperature, pressure, speed, weight, voltage, etc. Quantities have infinite variety of values.
- Digital Computer: Represents numerals, letters, or special symbols using digits (ON/OFF signals, 1/0). Operates on ON-OFF input and output signals.
- Hybrid Computer: Combination of analog and digital computers. Combines the speed of an analog computer with the memory and accuracy of a digital computer. Used for specialized applications requiring both types of data.
Computer Operations
- Input: Process of capturing or acquiring information. Accepting data/information to be processed using input devices. Information/data entered into a computer/device using an input device. Data is gathered manually, automatically, or both. Types include data, programs, commands, and user responses.
- Processing: Transformation process of converting input into output. An instance of running a program. Causes the computer to follow instructions from memory, performed by the Central Processing Unit (CPU). The CPU has three parts: Arithmetic/Logic Unit (ALU), Control Unit, and Input/Output (I/O) Unit.
- Arithmetic/Logic Unit (ALU): Performs arithmetic operations (addition, multiplication) and comparison operations.
- Control Unit: Controls the flow of data through the processor and coordinates activities of other units.
- Input/Output (I/O) Unit: Controls input and output devices.
- Output: Result of the transformation process or outcome of the process. Anything that comes out of a computer. Examples include reports, music, graphics, and video clips. Types include hard copy (printed on paper) and soft copy (unprinted digital document displayed on screen or other non-permanent means). Categories of computer output include text documents, graphics, and multimedia.
- Storing: Process of storing/retaining data/information/instructions for later retrieval. Capability to store information after processing. Used to store programs/data when not in use in the memory.
- Controlling: Directing the manner and sequence of operations.
Hardware vs. Software
- Hardware: Any part of the computer with a physical structure (e.g., monitor, keyboard).
- Software: Set of instructions that tells the hardware what to do and how to perform each task.
Basic Computer Components
- System Unit: Core of the computer system. The central processing unit (CPU) is the most important component, acting as the "brain." Random access memory (RAM) temporarily stores information used by the CPU while the computer is on. Almost every part of the computer connects to the system unit using cables.
- Computer Case: Houses all components. Serves to physically mount and contain components. Usually bundled with a power supply. Types: Tower and Desktop.
- Power Supply: Sends power to all other hardware components. Two types: AT and ATX (Advanced Technology Extended).
- CPU (Central Processing Unit): Brain of the computer, performs calculating and processing tasks.
- CPU Fan: Cools the CPU.
- Computer Memory (RAM): Random access memory, used to store information in electronic devices.
- Motherboard: Main circuit board; all internal/external components connect to it. Components include the CPU, chipset, RAM, ROM, BIOS (Basic Input Output System), buses, and ports.
- Hard Disk: Stores computer data and programs. Holds more data and is faster than floppy disks.
- Optical Disc Drive: Optical storage technology to store and play back data; some are readers only, others are both readers and recorders.
- Video Card: Provides display capabilities for the computer screen.
- Sound Card: Adds audio capability to the computer, providing high quality stereo output.
- Modem: Modulator-demodulator; enables data transmission over telephone or cable lines.
- Monitor: Allows users to see what the computer is processing.
- Input Devices: Keyboard, mouse
- Output Devices: Printer, speakers
- Operating System: Windows, macOS, Linux
Computer Categories
- Mobile Computer: Designed for portability and human-computer interaction; examples include personal digital assistants, smartphones, tablets, ultra-mobile PCs, and wearable computers.
- Microcomputer: Small, relatively inexpensive computers with a single microprocessor as their CPU (e.g., tower PC, desktop, laptop).
- Minicomputer: Midsized computers that lie between workstations and mainframes capable of supporting hundreds of simultaneous users.
- Mainframe: Large, expensive computers used in large institutions (government, banks) to handle and process large amounts of data quickly.
- Supercomputer: Fastest type of computer, used for complex calculations like weather forecasting, fluid dynamics, and scientific computations.
Desktop vs. Laptop
- Desktop Pros: Larger screen, variety of screen types/brands, longer lifespan, more power, easier upgrading, family/gamer friendly.
- Desktop Cons: Not portable, variety of wires/installation, additional purchase of keyboard/monitor/speakers, requires large space.
- Laptop Pros: Portable and light, variety of brands/styles, suitable for travel/business, all-in-one gadget.
- Laptop Cons: Less memory/RAM, smaller screen, susceptible to damage, may have poorer performance without being plugged in.
- Notebook: Usually smaller, and less powerful than a laptop.
- Netbook: Very small and portable, primarily for internet access and basic tasks.
Workstation
- Powerful, single-user computers with a more powerful microprocessor and higher-quality monitor.
- Can function as servers, providing files to client computers on a network.
- Usages: Engineering applications (CAD/CAM), desktop publishing, software development, and applications needing moderate computing power and high-quality graphics.
