Study Notes

Hardware Fundamentals

Motherboard: The principal circuit board, hosting components like the CPU, RAM, and expansion slots. Different form factors exist (e.g., ATX, mini-ITX).
Central Processing Unit (CPU): The computer's "brain," executing instructions. Key attributes include clock speed, core count, and cache size.
Random Access Memory (RAM): Volatile memory for data actively accessed by the CPU. Faster RAM enhances system performance. Different types (e.g., DDR3, DDR4, DDR5).
Storage Devices: Hard Disk Drives (HDDs) and Solid State Drives (SSDs). HDDs use spinning platters; SSDs employ flash memory. SSDs are typically faster and more durable.
Input Devices: Hardware for data input, like keyboards, mice, touchpads, and scanners.
Output Devices: Hardware displaying computer information, such as monitors, printers, and speakers.
Graphics Processing Unit (GPU): A specialized processor for accelerating graphics and image processing tasks. Part of video cards.
Power Supply Unit (PSU): Converts AC to DC power for computer components. A reliable PSU is essential. Types include ATX, SFX, and others.
BIOS (Basic Input/Output System): Firmware controlling basic computer functions during startup.
Expansion Slots: Motherboard slots for adding peripherals (e.g., graphics cards, sound cards).
Ports: Computer connections for peripherals and devices (e.g., USB, HDMI, Ethernet). Modern devices frequently have more USB ports.

Operating Systems (OS)

Operating System (OS): Software managing computer hardware and software resources. Common OSes include Windows, macOS, Linux.
Windows: A dominant OS known for its user-friendly interface. Versions include Windows 10 and 11.
macOS: Apple-developed OS, primarily used on Apple computers.
Linux: An open-source OS; numerous distributions are available.
Boot Process: The sequence of events initiating the OS startup.

Common Troubleshooting

Troubleshooting: Identifying and resolving software/hardware issues. Key steps include isolating the problem, checking device drivers, and examining system logs.

Networking Basics

Network: A system of interconnected devices. Key components include network interface cards (NICs).
Network Interface Card (NIC): Connects a device to a network (e.g., Ethernet, wireless). Modern devices largely use Wi-Fi cards.
Network Protocols: Rules for data transmission over a network. A key protocol is TCP/IP.

Software Fundamentals

Software: Instructions guiding computer actions. Types include application software, operating system software, and utility software.
Application Software: Software for specific tasks (e.g., word processing, web browsing, image editing). Examples include Microsoft Word, Google Chrome, Adobe Photoshop.
Operating System Software: The software controlling and managing computer hardware and software resources.
Utility Software: Software for specific computer tasks (e.g., disk cleanup, data security).

Mobile Devices

Mobile Devices: Smartphones and tablets. Common mobile operating systems include iOS and Android. Distinctions between phone and tablet form factors are important.
iOS: Mobile OS primarily found on Apple products.
Android: A mobile OS used by various vendors.

Security

Security: Protecting computer systems from unauthorized access and malicious activity. Implementing strong passwords, regular updates, and antivirus software is essential. Common risks include malware, phishing, and social engineering.
Passwords: Secure passwords prevent unauthorized access. Robust passwords include a mix of uppercase/lowercase letters, numbers, and symbols.
Antivirus Software: Protecting against viruses, malware, and other threats. Regular updates are crucial.
Data Backup: Data protection from hard drive failures, malware, and more. Regular backups are a best practice.
Physical Security: Protecting hardware from theft or damage. Locking computers and cables are good physical security measures.

Mobile device and tablet troubleshooting

Troubleshooting Steps: Common mobile device problems include connectivity issues and software error messages, Troubleshooting involves checking power, internet connectivity, and applications for errors.

Hardware Maintenance

Maintenance: Prolonging hardware lifespan through proper maintenance. Cleaning dust from components, using cables correctly, and updating drivers are examples.

Installing Software Applications

Installing Applications: Ensuring software and hardware compatibility. Proper procedures prevent future conflicts. Checking compatibility between software and operating systems prevents problems.
Software Compatibility: Applications and devices need to be compatible for proper operation. Incompatible programs won't function as expected.
Verification: Correct installation requires proper verification to eliminate installation errors.
