Welcome to our first post about solutions to our Sunday Quiz. From now on we are planning on carrying on and post solutions and explanations here on our blog. Enjoy
Q1 (Easy) What does RAM stand for?
“RAM” stands for Random Access Memory. It can store information of currently running programs and states. Important to note is though that as soon as it loses power all data is gone and cannot be recovered, also called volatile memory. From the “usable” memory types RAM is normally the quickest while still having a decent size. (RAM).
Q2 (Easy) What type of cache is the fastest?
There are multiple levels of cache that are normally built directly onto the CPU. Normally there are 3 levels with the L1-Cache being the fastest. These days the L1-Cache of a 2019 Ice Lake processor can hold up to 80KiB per core! The latency at this level is at about 1ns (nanosecond). (L1-Cache).
Q3 (Medium) What does HDMI stand for?
HDMI stands for High Definition Multimedia Interface and is a proprietary audio/video interface for transmitting uncompressed data. It was designed in December 2002 and still is a widely used standard. The current version is HDMI 2.1 and has a Bitrate of up to 48Gbit/s. Its maximum supported resolution is 10K at 120 Hz! (HDMI).
Q4 (Hard) What was the first Intel processor?
The first consumer CPU from Intel was the Intel 4004. It was released on the 14. November 1971. Its maximum clock rate was 740kHz and had 2250 Transistors. As a comparison, today’s CPUs can reach over 5GHz and have up to 39.54 billion transistors! (Intel 4004).
Q5 (Hard) How many bytes are one kilobyte?
This may be a tricky question. The correct answer is 1000 Bytes. The reason for this is that is an SI Unit. That means it uses the Base 10 for calculations. With kilo being 1000, 1 kilobyte resulting in 1000 Bytes (Mega = 1 000 000, Giga = 1 000 000 000). For explicitly saying something 1024 Byte big you have to use the prefix “kibi”.
