Study Notes
Computer Architecture
- Hardware layer consists of physical components of a computer.
- Four main layers: Hardware, Operating System, Software, User.
- User and Software layers facilitate human interaction with computers.
IT Support
- Essential aspect is understanding the human element.
Memory and Storage
- Programs are stored in RAM for CPU access.
- RAM is the computer's short-term memory.
- The motherboard is the foundation that holds components in place.
- MCC (Memory Controller Chip) acts as the bridge between RAM and CPU.
CPU Performance
- Overclocking refers to exceeding the number of clock cycles on a CPU.
Boot Process
- POST (Power-On Self-Test) checks hardware and ensures proper functioning.
- BIOS (Basic Input/Output System) initializes hardware and loads drivers.
- BIOS settings are stored in CMOS (Complementary Metal-Oxide-Semiconductor).
- To boot from a USB drive, adjust settings in the BIOS.
Operating Systems
- The macOS file manager is called Finder.
- Use the command 'touch' to create files in bash.
- An emulation of a physical machine is known as a Virtual Machine.
- Operating systems consist of Kernel and Userspace.
File Management
- Main components include file date, file system, and metadata.
Boot Sequence
- Final step in booting a computer is launching user space.
Graphical User Interfaces (GUI)
- Examples of GUI: iOS and ChromeOS.
Input/Output Devices
- Common I/O devices include monitors, speakers, and webcams.
Networking and IP Addresses
- IPv4 addresses are limited by the number of connected devices and existing websites.
- Primary protocol for creating the Internet is TCP/IP.
- IPv4's maximum number of addresses has been reached.
- The World Wide Web enables sharing more than just text on the Internet.
- Solutions for IPv4 limitations include Network Address Translation and implementing IPv6.
