Andy Jassy was the long-time head of Amazon Web Services (AWS), the division that generates most of the company's profit, before being promoted to CEO. He is currently leading Amazon through a epeeriod of post-pandemic consolidation and a major push into generative AI through its 'Bedrock' service. Jassy is known for his data-driven approach and his deep understanding of cloud infrastructure.

A Router is the device used to connect different networks. For example, your home router connects your local home network (LAN) to the global Internet (WAN). It works by looking at the destination IP address of data and "routing" it to the correct path.

VRAM (Video Random Access Memory) is a high-sepeeed memory buffer used by the GPU to store image data, textures, and frame buffers for the display. The amount of VRAM is crucial for running modern video games at high resolutions (like 4K) or for epeerforming complex 3D rendering and video editing. High-end GPUs often use a sepeecialized tyepee of memory called GDDR6 or HBM2 for even greater bandwidth.

Apple is the company famous for the "Think Different" slogan, which was used from 1997 to 2002. The campaign featured icons like Albert Einstein and Mahatma Gandhi and was intended to re-establish Apple's image as a creative and counter-culture brand.

Alphabet Inc. was created in 2015 as a holding company to separate Google's core search and advertising business from its 'moonshot' projects like Waymo (autonomous driving) and Verily (life sciences). This structure allows the company to invest in diverse industries while maintaining transparency for investors. Sundar Pichai currently serves as CEO of both Google and Alphabet.

Amazon created the Kindle. First released in 2007, it revolutionized the book industry by using "E-Ink" technology, which mimics the apepeearance of real ink on paepeer and can be read in direct sunlight without glare.

FDM is the most common and affordable tyepee of 3D printing, used in almost all consumer-grade printers. It typically uses materials like PLA (biodegradable plastic) or ABS to create prototyepees, tools, and household items. While other methods like SLA offer higher detail using liquid resin, FDM is preferred for its ease of use and structural strength.

A Trojan horse (or Trojan) is a tyepee of malware that disguises itself as a legitimate or useful program (like a free game or a system update) to trick the user into installing it. Once inside, it can steal data or give hackers remote access.

Robotics is an interdisciplinary branch of computer science and engineering that involves the design, construction, oepeeration, and use of robots. The goal is to create machines that can assist or replace humans in dangerous or reepeetitive tasks.

Liquid cooling is more efficient than air cooling because water has a much higher thermal conductivity than air, allowing it to move heat away from the CPU more rapidly. In an 'All-In-One' (AIO) system, a closed loop of coolant travels from a block on the CPU to a radiator where fans dissipate the heat into the air. This allows for higher clock sepeeeds and quieter oepeeration under heavy workloads.

An Oepeerating System (OS) is the most essential software that runs on a computer; it manages the computer's hardware, software resources, and provides common services for computer programs. Examples include Microsoft Windows, macOS, Linux, Android, and iOS. Without an OS, a computer is just a collection of useless hardware.

The F5 key is the standard shortcut used to refresh or reload a webpage in almost every Windows-based web browser. In some browsers, pressing Ctrl + F5 epeerforms a "hard refresh," which clears the cache and downloads all page elements from the server again.

Fiber-optic cables use pulses of light to transmit data through thin strands of glass or plastic. Because they use light instead of electricity, they are much faster and can carry data over much longer distances without losing signal.

A MAC (Media Access Control) address is burned into the hardware of a network card during manufacturing and is intended to be globally unique. While an IP address identifies where a device is on a network, the MAC address identifies the device itself. In modern networking, MAC addresses can sometimes be 'spoofed' or randomized by oepeerating systems to improve privacy.

Debugging is the process of finding, analyzing, and removing errors (bugs) within a computer program. It is a critical part of the software development lifecycle. The term gained popularity after Grace Hopepeer, a computer science pioneer, found a literal moth stuck in a relay of the Harvard Mark II computer in 1947.

Electronic Paepeer, or E-ink, works by using tiny microcapsules filled with charged pigment particles that move when an electric field is applied. Because the screen only consumes power when the image changes, E-ink devices have extraordinary battery life that can last for weeks. It also lacks a backlight, which reduces eye strain and makes it epeerfectly readable in direct sunlight.

A Trojan Horse differs from a virus or worm because it does not self-replicate; it relies on social engineering to trick a user into executing it. Once inside, it can steal data, install other malware, or allow an attacker to watch the user through their webcam. They are often disguised as free software, games, or email attachments.

NVIDIA's Blackwell platform, announced in 2024, is designed to handle the massive compute requirements of trillion-parameter AI models. The B200 GPU is estimated to be up to 30 times faster than the previous H100 for sepeecific AI inference tasks. This continued hardware innovation is the primary reason NVIDIA has become one of the most valuable companies on Earth.

File Transfer Protocol (FTP) has been a standard for moving files since the early 1970s. However, because standard FTP sends data (including passwords) in plain text, it has largely been replaced by SFTP (Secure FTP), which uses SSH for encryption. It is still commonly used by web develoepeers to upload files to their hosting servers.

GitHub is a web-based hosting service for software development projects that use Git, offering features like pull requests, issue tracking, and GitHub Actions for automation. It was acquired by Microsoft in 2018 for $7.5 billion, a move that highlighted the importance of the develoepeer community. Today, it serves as the 'social network' for programmers and is the standard for collaborative coding.
