What is Volatile Memory?

Temporary data storage in a computer, lost when power is off. Used for short-term data handling, vital for applications and the operating system.

What is Nonvolatile Memory?

Permanent data storage, retaining information even without power. Used for storing system firmware and other essential data.

What is RAM?

Short-term or main memory in a computer, providing temporary storage for running apps and the operating system.

What are RAM Modules?

Memory modules on a circuit board connected to the motherboard, used for data storage in RAM.

Study Notes

Types of Memory

  • Volatile memory, such as RAM, loses data when power is off; essential for short-term data storage.
  • Nonvolatile memory, like ROM, retains data without power; used for permanent storage of system firmware.

RAM (Random Access Memory)

  • Functions as short-term or main memory, storing data temporarily for applications and operating systems.
  • Composed of memory modules on a circuit board connected to the motherboard.

Thrashing

  • Occurs when insufficient RAM causes excessive data swapping between RAM and virtual memory, leading to poor system performance.
  • Resulting system becomes sluggish or unresponsive.

Read-Only Memory (ROM)

  • Provides essential data during startup; contents are not continually overwritten by the operating system.
  • Essential for system boot processes and retains information permanently.

EEPROM (Electrically Erasable Programmable Read-Only Memory)

  • A nonvolatile variant of ROM that can be modified, allowing updates without power loss.

Flash Memory

  • A faster, more updateable type of ROM that has largely replaced traditional ROM in modern computers.

Firmware

  • Permanent software stored in a chip; the BIOS on a motherboard serves as a key example.

Cache Memory

  • Temporarily holds frequently accessed data or programs, allowing for quicker access than standard RAM.

Levels of Cache Memory

  • Level 1 Cache (L1): Integrated within the CPU for rapid access to frequently used data.
  • Level 2 Cache (L2): A memory bank on the CPU chip or motherboard, supporting faster data retrieval.

Heat Sink

  • A metal component designed with cooling fins to dissipate heat from integrated chips like the CPU.

System Requirements

  • Manufacturer-recommended minimum specifications for storage, memory, and processing to ensure software operation.

Software Updates and Patches

  • Software Patch: An update to fix vulnerabilities or improve software functionality.
  • Software Update: A small code section replacing part of an existing program.
  • Service Pack: A collective package of updates, fixes, or enhancements delivered as a single file.
  • Software Upgrade: A complete new version of software with additional features.

Software Installation

  • The process of copying programs and data to a hard disk, preparing them for use.

Update Methods

  • Automatic Update: A built-in tool that checks for updates and downloads them automatically.
  • Manual Update: Requires user intervention to find and install updates, often visiting the developer’s website.
