RASPBERRY PI UPDATED MOCK TEST WITH
TROUBLESHOOTING SCENARIOS AND
RATIONALES 2026
◉ What is Raspberry Pi's Operating System?
Answer: Variant of first Linux Version "Debian" known as "Raspbian"
◉ What are some applications software for Rasp Pi?
Answer: Surf Internet with a Browser, High Definition Video,
Spreadsheets and Word Processing, Games
◉ What are some of the compilers and interpreters used with a Rasp
Pi?
Answer: Compilers and Interpreters: C, C++, Java, Python, R, etc.
◉ What is a Raspberry Pi?
Answer: Raspberry Pi is a low cost, credit card sized computer that
can plug into a display monitor or TV, standard keyboard and mouse,
hard disk and USB storage devices and connect to the network wired
or wirelessly.
◉ How much memory does a Raspberry Pi have?
, Answer: 1GB RAM
◉ CPU of Raspberry Pi
Answer: 1.2 GHz Quad-Core ARM Cortex
-(The ARM Cortex-A9 MPCore is a 32-bit processor core)
◉ What's Headless mode?
Answer: Raspberry Pi is typically used in environments where
attaching a display, keyboard, mouse, etc., is not feasible due to
environment factors, cost and not required by applications software
.
Operating a Raspberry Pi by directly accessing the OS terminal or
the Desktop via VNC over the network (WiFi or Ethernet) without
the need for a monitor, keyboard or a mouse is called Headless
mode.
◉ Duty Cycle
Answer: T = 1/f
DC = Pulse Width/T
Duty cycle is the proportion of time during which a component,
device, or system is operated. In electronics, duty cycle is the
percentage of the ratio of pulse duration, or pulse width (PW) to the
total period (T) of the waveform
