Domain 1.1 Compare & contrast notational Systems
This base-16 notational system uses characters 0-9 and A-F.
What is hexadecimal?
This stage of the computing process is responsible for turning raw data into useful information.
What is processing?
This is the smallest unit of data a computer can process.
What is a bit?
This Windows file system supports encryption, compression, and journaling.
What is NTFS?
This number system only uses 0s and 1s to represent data.
What is binary?
This type of device sends data into a computer system.
What is an input device?
This measures how fast a processor can complete cycles per second.
What is hertz?
This file system is compatible with most operating systems but has a 4GB file size limit.
What is FAT32?
This base-10 system is the one we use in everyday math.
What is decimal?
This is the phase where data is saved for later use, like on a hard drive.
What is storage?
This letter is used to represent bits, not bytes.
What is lowercase b?
📝 Be careful—b is bits and B is bytes. 1 Byte = 8 bits.
This part of a drive must be created before it can store files.
What is a partition?
This base-2 system is used by all computers to represent data and instructions using only two values.
What is binary?
📝 Binary is the foundation of all computer processing. Each bit is either a 1 (on) or 0 (off), allowing computers to handle logic and data storage through electrical signals.
What are the four stages of the computing process, in order?
What is Input, Processing, Output, Storage?
📝 This cycle describes how data moves through a computer—from entering via input devices to being stored for later use.
A network connection that transfers 1,000,000 bits per second is operating at what speed?
"Mega" means one million, and bits per second is the standard unit for measuring data transfer speed over a network.
This file system, used by older Windows systems and USB drives, cannot store a file larger than 4GB.
What is FAT32?
📝 FAT32 is compatible across OS platforms but has significant limitations, including its 4GB file size cap and lack of security features.
This base-16 digit is equal to the binary value 1111
What is F?
In hexadecimal, F represents the decimal number 15. It’s used to compactly represent four binary bits (a nibble).
This component of a computer reads instructions from memory and executes them, one cycle at a time, based on clock speed.
What is the CPU (Central Processing Unit)?
📝 The CPU acts as the “brain” of the computer. It carries out instructions at speeds measured in MHz or GHz, depending on its clock rate.
If a file is 4 MB (megabytes), how many bits is that?
A) 4 million
B) 32 million
C) 512 thousand
D) 4 thousand
What is B) 32 million?
📝 There are 8 bits in a byte. So, 4 MB = 4 million bytes × 8 = 32 million bits.
This Linux file system supports journaling and is the fourth version in a long line of extended file systems.
What is ext4?
📝 ext4 is the default file system for many Linux distributions. It supports journaling, large volume sizes, and high-performance file operations.
