Study Notes
Computer Systems Components
- RAM is the component responsible for short-term data storage.
- The CPU serves as the main processor for executing data and instructions.
- The power supply converts alternating current (AC) to direct current (DC).
- The CPU typically has the fastest performance among computer components.
- Hard disks do not qualify as optical storage devices.
- RAM is categorized as a volatile memory, not suitable for long-term data storage.
- Flash drives utilize persistent memory chips to retain data.
- Compact disks store data through microscopic light and dark spots.
Storage Devices Characteristics
- Hard Disk Drives (HDD) are thick magnetic disks with aluminum platters that use read/write heads for data access.
- Solid State Drives (SSD) offer storage capacity comparable to small hard drives and feature no moving parts for improved durability.
- Optical Disk Drives read and write data using lasers on reflective surfaces.
- HDDs can store multiple terabytes (TB) at a low cost per megabyte.
- SSDs offer faster data access and longer life compared to traditional storage devices.
- Optical disks are cost-effective and portable, ideal for multimedia storage.
Troubleshooting and Maintenance
- After confirming a troubleshooting theory, establish an action plan and identify potential outcomes.
- The troubleshooting process begins with problem identification and requires gathering information followed by duplicating the issue.
- Programs or applications currently running in an operating system are termed "processes."
- To resolve an unresponsive application, the Task Manager should be used to terminate it.
Operating Systems and Software Types
- Embedded operating systems (OS) are found in devices like gaming consoles and smart TVs.
- Utility software encompasses tools like disk cleaners, antivirus programs, and backup utilities.
- Operating systems provide a platform for applications to function.
- Device drivers manage communication between the computer and peripherals.
- Firmware is pre-installed software in electronic devices like cars and home appliances.
Driver and Hardware Management
- For hardware issues like a non-functional sound card, checking for updated drivers on the vendor's website is recommended.
- Device Manager in Windows is the utility used for manually updating installed drivers.
- If a new printer is not recognized by the computer, installing the latest printer driver from the manufacturer's website is necessary.
- The Settings application in Windows allows users to manage accounts, change passwords, and customize their computing environment.
