Introduction to Computing

Intended Outcomes: Explain the evolution of computers and identify types of hardware and software.

Hardware vs. Software

Hardware: Physical components (e.g., printers, monitors).
Software: Programs that instruct hardware (e.g., word processors, games).

Monitors

LCD Monitors: Thinner, used in notebooks and flat screens, better quality than CRT.
Video Card: Influences graphics rendering with memory measurements (32 MB for general, 128 MB for graphics-intensive).
Buying Tips: Opt for 17” or larger monitors with a dot pitch of 28 or better.

Printers

Types: Laser, Ink Jet, Dot Matrix.
- Laser: High speed, quiet, quality output; can scan and photocopy.
- Ink Jet: Quiet, reliable, good for color printing.
- Dot Matrix: Older technology, now mostly superseded.
Speed: Measured in pages per minute (PPM); laser printers range from 20-45 PPM.
Quality: Dots per inch (DPI) measurement; higher DPI results in better quality.

Basic Processing Cycle

Central Processing Unit (CPU): The brain of the computer executing all operations.

Memory Storage

Memory: Composed of bits (0s and 1s); bytes consist of 8 bits.
Storage Hierarchy:
- Kilobyte (KB): ~1,000 bytes
- Megabyte (MB): ~1 million bytes
- Gigabyte (GB): ~1 billion bytes.

CPU Overview

Brands: Predominantly Intel and AMD.
Performance Indicators: Clock speed measured in MHz or GHz, affecting operation cycles per second.

Internal Memory

RAM (Random Access Memory): Needed for quick data access and system performance; at least 256 MB recommended.
ROM (Read Only Memory): Contains essential system information, cannot be modified.

External Memory

Floppy Drives: 3.5” high density (1.44 MB).
Hard Drives: Minimum 40 GB for modern storage needs.
Optical Drives: CD-ROM (650 MB), DVD-ROM (up to 17 GB), CD-RW and DVD-RW for writing data.

Other Storage Devices

USB Drives: Common for 64-512 MB storage.
Zip Drives: Offer storage from 100 MB to 2 GB.

Networking

Types: LAN (Local Area Network), WAN (Wide Area Network), and wireless connections.
Modems: Essential for computer communication over phone lines; speed measured in bits per second (bps).

Software Types

Systems Software: Facilitates core functions (e.g., DOS, Windows, Linux).
Applications Software: Enables task completion (e.g., word processing, spreadsheets).

Software Legal Issues

Commercial Software: Limited to backup copies and one machine use.
Shareware: Can be copied and shared but requires payment for continued use.
Freeware: Can be used without restriction.

Virus Awareness

Viruses: Malicious code that can corrupt files and spread between computers.
Protection Measures: Avoid untrusted file sources, use virus detection software, and update frequently.

Buying Advice for Computers

Minimum Requirements: 2 GHz CPU, 256 MB of RAM, 40 GB hard drive, CD-RW, and appropriate printers.
Software Bundles: Recommended productivity and reference software included with purchases.
