3. Get your brains logged on!
Put these terms in order (smallest to largest):
C. Bit 1 bit
D. Nibble 4 bits
F. Byte 8 bits (2 nibbles)
G. Kilobyte 1024 bytes
B. Megabyte 1024 kilobytes
E. Gigabyte 1024 megabytes
A. Terabyte 1024 gigabytes
4. By the end of this lesson:
• All of you be able to explain the need for
secondary storage and describe common
storage technologies such as optical, magnetic
and solid state. You will also understand the
terms bit, nibble, byte, kilobyte, megabyte,
gigabyte and terabyte.
• Most of you will be able to select suitable
storage devices and storage media for a given
application.
• A few of you will be able to justify your choice
using characteristics such as capacity, speed,
portability, durability and reliability.
5. Why 1024 – why not 1000?
• Remember, computers use binary which
doubles each time, i.e.
1 2 4 8 16 32 64 128 256 512 1024
• So how many bytes are in 2 megabytes?
7. Your Task: which storage?
1. Go to isambardcomputing.pbworks.com
2. Go to Theory > Storage Devices page
3. Open the “which storage exercise” and
identify the most suitable storage media
for each scenario.
4. Use the storage comparison table in the
teacher’s notes to help you.
