Software
The number of bytes in 3 KiB
What is a 3072 bytes
These are two functions of an operating system
What is an 1) memory management, 2) user account management, 3) security, 4) file management, human-computer interface, 5) multitasking, 6) peripheral management
This is where the programs are stored/loaded from in the von Neumann computer
What is memory/RAM
This is one of the 3 types of touchscreen technology
What is 1) resistive, 2) capacitive, or 3) infra-red
Performs the maths in the CPU
What is the Arithmetic/Logic Unit (ALU)
These are two applications of hexadecimal
1) HTML Colours
2) Memory Dumps
3) MAC addresses
4) IPv6
Having more than one program open at a time
What is multitasking
These are the parts of the von Neumann computer
What are ALU, CU, memory, and I/O
This is the type of printer best used for printing many black and white copies quickly
What is laser printer
These are two components that make up the size (and quality) of a sound file
What is sample resolution and sample rate
These are the two types of human computer interfaces
What are GUI and CLI
These are 5 registers
What are PC, MAR, MDR, CIR, and ACC
This is one advantage that HDD has over SSD
What is can do more writes. Useful for servers.
The CPU can only read this kind of language
What is machine code
These are two kinds of ways to encode text data
What is ASCII and Unicode
This is one advantage and one disadvantage of virtual memory
What is 1) can have more programs open than RAM to handle them, 2) can slow down the computer with constant loading pages into/out of storage
These are the directions of the buses
What are unidirectional for address, bidirectional for data, and either for control
These are the names of 4 sensors
What are 1) temperature, 2) light-level, 3) sound level, 4) magnetic, 5) pressure, 6) pH, 7) gas, 8) humidity/moisture
These are 4 different things that cause an interrupt to happen
What is 1) error (like trying to read memory that's reserved), 2) user input, 3) printer buffer empty, and 4) virtual memory page needed but not in memory
This is a lossly method for compressing text (explain)
Like A can be 10011 (which is much shorter than 8 bits)
These are 3 examples of utility software
What are 1) anti-virus, 2) encryption, 3) back-up software, defragmentation, 4) screensaver
What is 1) address in PC is sent to MAR, value in PC is incremented, address in MAR is sent along address bus, "read" signal is sent along control bus, and the instruction in memory is sent along data bus to MDR, finally instruction in MDR is sent to CIR
These are 3 things that the CPU in a digital camera or mobile phone when taking a photo
What is 1) handles auto zoom, 2) removes red eye, 3) auto flash, 4) adjusts shutter speed (because of light level), adjusts size of image
