Computer Hardware and Networking Review

Practice flashcards covering CPU specs, RAM usage, GPU types, networking concepts, and storage unit conversions based on lecture notes.

What is the primary function of a processor or CPU (Central Processing Unit)?

The CPU is the main component responsible for carrying out instructions and calculations in a computer.

What are the two most common CPU manufacturers for desktop and laptop computers and examples of their product lines?

Intel (examples: Core i3, Core i5, Core i7, Core i9) and AMD (examples: Ryzen 3, Ryzen 5, Ryzen 7, Ryzen 9).

Why is comparing CPUs based solely on clock speed (GHz) insufficient?

A proper comparison must evaluate generation/architecture, number of cores, threads, cache, power consumption (TDP), and independent benchmarks.

What is RAM (Random Access Memory) and what is its role?

RAM is the computer's short-term working memory where Windows and active program data are loaded so the processor can access them quickly.

What occurs when a computer system lacks sufficient RAM?

The computer starts using the storage drive as virtual memory/pagefile, causing the computer to become noticeably slower because storage is much slower than RAM.

According to the general RAM guide, what typical use is associated with $32\,GB$ of RAM?

Gaming, programming, video/photo editing, and demanding multitasking.

What are the two basic types of graphics options available in computers?

Integrated graphics (built into the CPU or processor package) and dedicated graphics cards (separate cards with their own GPU and usually VRAM).

What is the distinction between Wi-Fi and the Internet?

Wi-Fi is a wireless networking technology that connects a device to a router/access point, whereas the Internet is the global network connecting networks and computers worldwide.

What is the sequence of connections that illustrates how a laptop reaches a website?

$$\text{Laptop} \rightarrow \text{Wi-Fi} \rightarrow \text{Router} \rightarrow \text{Internet} \rightarrow \text{Website}$$

What are the exact conversion factors for KB, MB, GB, and TB according to the file size conversion guide?

$1\,KB = 1,024\,bytes$, $1\,MB = 1,024\,KB$, $1\,GB = 1,024\,MB$, and $1\,TB = 1,024\,GB$.
