How many MB in a GB?
In the decimal system (used by storage manufacturers), 1 GB = 1000 MB. In the binary system (used by Windows), 1 GiB = 1024 MiB.
Difference between bit and byte?
A bit (b) is the smallest unit (0 or 1). A byte (B) is 8 bits. Internet is bits; storage is bytes.
How to convert Bits to Bytes?
Divide the number of bits by 8. Example: 800 bits / 8 = 100 Bytes.
How to convert Bytes to Bits?
Multiply the number of bytes by 8. Example: 100 Bytes * 8 = 800 bits.
What is a Kibibyte (KiB)?
A Kibibyte (KiB) is a binary unit of data equal to 1024 bytes, distinct from a Kilobyte (KB) which is often 1000.
Why is 1TB only 931GB?
Manufacturers use decimal (1000) math; Windows uses binary (1024) math. The actual byte count is the same.
How many KB in a MB?
1 Megabyte (MB) = 1000 Kilobytes (KB) in decimal, or 1024 KB in binary contexts.
What is a Petabyte?
A Petabyte (PB) is equal to 1000 Terabytes (TB) or 1,000,000 Gigabytes (GB).
How many bits in a Kilobit?
1 Kilobit (Kb) equals 1000 bits.
What comes after Terabyte?
Petabyte (PB), Exabyte (EB), Zettabyte (ZB), and Yottabyte (YB).
Is Mbps the same as MB/s?
No. Mbps is Megabits per second (speed), while MB/s is Megabytes per second (file size). 8 Mbps = 1 MB/s.
How to convert TB to GB?
Multiply by 1000 (decimal) or 1024 (binary). Example: 2 TB = 2000 GB or 2048 GiB.
What does 'k' stand for?
'k' stands for kilo, meaning 1000. However, in computing, it historically meant 1024.
How many GB in a TB?
There are 1000 GB in 1 TB (decimal) or 1024 GiB in 1 TiB (binary).
What is a Nibble?
A Nibble is 4 bits, or half a byte.
How much data is a movie?
A typical HD movie is 4-6 GB. A 4K movie can be 20-50 GB.
How much data is a song?
A high-quality MP3 song is usually between 3 MB and 10 MB.
How much data is a photo?
A smartphone photo is typically 3-5 MB. RAW photos can be 25 MB+.
What is a Mebibyte?
A Mebibyte (MiB) is 1024 Kibibytes, or 1,048,576 bytes.
What is Exabyte?
An Exabyte (EB) is 1000 Petabytes. It is a massive unit of storage used for big data.
Calculate file transfer time?
Use the N28 Bandwidth Calculator. Generally: Size / Speed = Time.
Does formatting reduce size?
Yes, file system structures occupy a small amount of space, reducing usable capacity.
What is a Word in computing?
A Word is the natural unit of data for a processor, typically 32 bits or 64 bits.
Is 1000 GB exactly 1 TB?
In the decimal system (SI), yes. In the binary system (IEC), 1024 GiB = 1 TiB.
What unit does Mac use?
macOS uses decimal (base 10) measurements since Snow Leopard (10.6), so 1 GB = 1000 MB.
What unit does Windows use?
Windows uses binary (base 2) measurements but labels them as standard units (KB, MB), causing confusion.
How many bytes in a KB?
1000 bytes (SI) or 1024 bytes (Binary/Legacy).
What is b vs B?
Lowercase 'b' is bit. Uppercase 'B' is Byte.
How to convert GB to MB?
Multiply by 1000 (or 1024). 5 GB = 5000 MB.
How big is a text file?
Plain text takes 1 byte per character (ASCII). A 1000-word essay is about 5-6 KB.
What is overhead?
Data required for transmission control (headers), which reduces effective throughput.
Gigabits in a Gigabyte?
There are 8 Gigabits in 1 Gigabyte.
What is a Yottabyte?
The largest named unit in the SI system, equal to 1 septillion bytes.
Is cloud storage decimal?
Most cloud providers (Google, Dropbox) use decimal (1GB = 1000MB) for billing clarity.
Binary to decimal size?
Multiply binary size by 1.024 for KB, 1.049 for MB, 1.074 for GB.
What is storage capacity?
The amount of data a storage device can hold, usually measured in GB or TB.
How much RAM do I have?
RAM is typically measured in binary Gigabytes (GiB), displayed as GB.
What is the size of a DVD?
A standard single-layer DVD holds 4.7 GB.
What is the size of a Blu-ray?
A standard single-layer Blu-ray holds 25 GB.
Can I convert PB to TB?
Yes, multiply Petabytes by 1000 (or 1024) to get Terabytes.
