Computer data storage for programs currently in use.

Double Data Rate Synchronous Dynamic Random-Access Memory, a type of RAM.

Part of the CPU used for calculations.

Small memory stores in the CPU for temporarily holding data during processing.

Used to transfer information between main memory and other peripherals.

Set of electronic components managing data flow between processor, memory, and peripherals.

Method for accessing different memory locations in x86 architecture.

Different architectures with different memory access capabilities; 32-bit can address 4GB, 64-bit can address a vast (18 quintillion) amount.

Processors that can handle significantly more data than 32-bit processors, due to a larger address space, typically allowing for greater performance and larger memory capacity.

Multiple processing units within a single CPU, allowing for faster processing by handling tasks in parallel.

A 64-bit operating system is essential for 64-bit processors to fully utilize their memory capabilities and address space.

A technique where a portion of the hard drive is used as virtual RAM, allowing the system to hold more data than physically available in RAM.

The process of transferring data between RAM and the swap file on the hard drive, when RAM is full.

A small, fast memory within the CPU that stores frequently accessed data for quick retrieval, enhancing performance.

Multiple levels of cache memory, with smaller, faster L1 closer to the CPU and larger, slower L2/L3 for less frequently accessed data.

A balance between the speed of accessing a cache and the likelihood of finding the data needed by the CPU (hit rate).

GP stands for 'Power On Self Test' or 'Pre-Operating System Test'. It's a series of checks the computer runs when you power it on, making sure everything's working correctly before loading the operating system.

The main types of disk storage are: Mechanical Hard Disk Drives (HDDs), Solid State Disks (SSDs), Flash Drives (USB keys), Tape Drives (mostly obsolete), and Optical Drives (CDs and DVDs).

An HDD is a mechanical storage device that uses spinning platters with magnetic coatings to store data. It has moving parts (like a record player!) and is generally slower than an SSD.

The main difference is that an SSD uses flash memory, which is much faster than the magnetic platters in an HDD. SSDs have no moving parts and are therefore more durable and faster.

An SSD is a type of storage device that uses flash memory to store data. It's faster, quieter, and more durable than an HDD because it has no moving parts.

Access time refers to how long it takes a storage device to find and retrieve data. SSDs have much faster access times compared to HDDs, making them ideal for faster program loading and responsiveness.

SSDs offer faster access speeds, better reliability (due to no moving parts), and quicker loading times. They are generally more expensive than HDDs.

HDDs are much cheaper than SSDs for larger storage capacities and are still a good option for storing less frequently accessed data.

Offers benefits like improved performance, reduced software costs, instant updates, and unlimited storage capacity.

Includes concerns like security risks, data storage location, market dominance of major providers, trust issues, and dependency on internet access.

A service that stores and manages data remotely, allowing access from various devices.

A system for storing data on a network, accessible to multiple users.

Before choosing a network storage solution, consider factors like security, reliability, cost, and scalability.

An older file system used in older operating systems, such as Windows 95/98. It stores file data in clusters (blocks) on the drive, with a table to keep track of their location. It's simpler than NTFS but less secure and efficient.

A newer, more advanced file system commonly used by Windows operating systems. It allows more features, such as advanced security, permissions, and disk space management.

A method where a file's data is stored in sequential blocks on the drive, making access fast. However, this is difficult to maintain as files grow or are deleted.

When a file's data is scattered across the hard drive in non-sequential blocks, making access slower and leading to reduced disk space.

A dedicated server device designed for sharing files across a network. It doesn't run other server tasks like email or authentication.

The ability to add more storage space to a NAS device without needing to shut it down for maintenance or upgrades.

Unlike servers in server-centric systems that handle everything, NAS devices focus solely on file storage and sharing. The actual processing is still handled by the server.

The server manages data processing, while the NAS device provides storage and delivers data to users. This separates storage from the server's core functions.

A high-speed network dedicated to storage devices, allowing multiple servers to access shared storage. It's like a dedicated superhighway for data.

SAN is preferred for large databases due to its high performance and direct access to storage. NAS is better suited for file sharing and low-volume access.

Delivering computing services (servers, storage, software) over the internet, allowing access from anywhere. It's like renting a computer and software in the sky.

A cloud-based model where software is delivered over the internet and accessed through a web browser. You don't need to install it on your computer.

Cloud computing offers benefits like accessibility, scalability, cost-effectiveness, and reduced management overhead.

Combining storage devices from multiple locations into a single, centrally managed SAN, improving efficiency and reducing costs.

SAN enables multiple servers to share data on the same storage, making it accessible across the network.
