Hard Drives
- Hard disk drives do not use expansion slots, but rather connect directly to the motherboard.
- Solid-state drives (SSDs) provide faster bootup times and more space than conventional hard disk drives (HDDs).
Memory
- Virtual memory is hard drive space used as extra memory when the system runs low on physical memory.
- SODIMMs are made for laptops, while DIMMs are for desktop computers.
BIOS

- To stop a process in Windows, use the Task Manager.
- When you copy a file, the original file remains intact, and a new version of that file is created elsewhere on the hard drive.
Directories
- The number of subdirectories allowed within a single directory depends on the operating system.
- A Linux-based OS is called a distribution, which is a combination of the kernel, shell, and utilities needed for a fully functional OS.### Preparing a Hard Drive for Storage
- Before using a hard drive for file storage, it needs at least one partition.
- Once partitioned, the drive needs to be formatted, which installs a file system.
Updating a Windows Driver
- To update a Windows driver for a sound card, use the Device Manager utility.
Metadata
- Metadata is information about a file, such as its name, size, creator, and security.
- It is not part of the file itself, but rather data about the file.

Productivity Software
- Word processing, spreadsheets, and presentation software are examples of productivity software.
- Subscription software requires the user to pay yearly.
Software Compatibility
- When considering software compatibility, the two most important factors are whether the software was written for the operating system and if the computer has enough hardware to run the application.
Printer Installation
- If a printer driver is missing, visit the manufacturer's website to download and install it.
Application Delivery Methods
- Cloud-hosted apps require Internet access.
Antivirus Software
- For security software, such as antivirus protection, update the definition file at least once a week or set the software to update automatically.
Product Keys
- Software product keys are typically included on the package in which the installation CD-ROM was shipped or in an email from the manufacturer.
Private Browsing
- Private browsing doesn't guarantee anonymity, but it doesn't use any of your cache or cookies, making it less likely that the website can determine your identity.
Hexadecimal Format
- Hexadecimal is also known as base 16 and uses the numbers 1 to 9 and letters A to F.
Code Concepts
- Functions and methods are used to break code into small, reusable segments.
- Arrays and vectors are containers for data, with arrays containing one data type and being fixed in length, and vectors being more flexible, containing multiple data types and being dynamic in length.
