FIRST PROBLEM




Step 1: Convert A4 dimensions from millimeters to inches.
1 inch = 25.4 mm

  • Width: 210÷25.4≈8.27 in

  • Height: 297÷25.4≈11.69 in

Step 2: Multiply by desired print DPI (200 dpi).

  • Width: 8.27×200≈1654 pixels

  • Height: 11.69×200≈2338 pixels

    Required resolution at 200 dpi: 

  • 1654 × 2339 pixels

WHAT IS THE PROCESSOR

  THE PROCESSOR (CPU) A CPU, or Central Processing Unit, is the "brain" of a computer, responsible for executing instructions from software and performing the calculations that make a device work. It fetches, decodes, and processes instructions from memory, managing the flow of data and coordinating with other components to run the operating system and applications. The CPU is a crucial hardware component in virtually all computing devices, including computers, servers, and smartphones. https://www.pccomponentes.com/procesador-procesador-intel-core-i5-7500-4-nucleos-34-ghz-38-ghz-turbo-lga1151-tray?campaigntype=eshopping&campaignchannel=shopping&gad_source=1&gad_campaignid=12885548290&gclid=Cj0KCQjw3OjGBhDYARIsADd-uX7CW1HWmLakbPxowEXQFFpcGOaIE5HCWxipWm6b90GhOPOcK514nVMaAsgAEALw_wcB

He has an important job and manage sensible information about clients and business. I think this is not a good idea to use public wi-fi connections to do so… What do you think and why… Problem Description Name of the Issue: Using Public Wi-Fi for Sensitive or Confidential Work Definition: Public Wi-Fi refers to free or open wireless internet networks provided in places like libraries, cafés, airports, and cultural centers. These networks are often unsecured , meaning anyone nearby can connect without authentication. Because of this, data sent through these networks can sometimes be intercepted by attackers using relatively simple tools. This exposes sensitive information—such as client data, business documents, passwords, or financial info—to significant risk. Why It’s a Problem Public Wi-Fi is convenient, but not safe for handling sensitive information b...

THE PERIPHERALS Peripherals are  external or internal hardware devices, like mice, keyboards, monitors, and printers, that connect to a computer to expand its capabilities by providing input, output, or storage functions .  These devices are not core components of the central processing unit (CPU) but rather auxiliary tools that allow for user interaction, information display, or data management.
