1.What is a Digit
A digit is a single place that can hold numerical values between 0 and 9. Digits are normally combined together in groups to create larger numbers.
2.“normal” counting numbers used in everyday life are based on what sequence of numbers?
They are based on the binary number system
3. Where does the word bit originate from?
The word bit is a shortening of the words "Binary digIT."
4.Binary numbers don’t use base 10. What base do they use? What digits are available in base 2? They use base 2. Digits avaliable in base 2 are increasing powers of 2.
5. What is a byte?
Bits are rarely seen alone in computers. They are almost always bundled together into 8-bit collections, and these collections are called bytes.
6.How many bytes in a kilo, mega, giga and tera bytes.
kilo= 1,024
mega= 1,048,576
giga= 1,073,741,824
tera= 1,099,511,627,776
7.Complete the following conversions;
1000 Mb = 1Gb
500 Gb = 512 000Mb
5000 Kb = 5Mb

Mobile internet Device (MID)
What are the benefits this processor offers mobile devices?
It provides low power and is designed specifically for a new wave of Mobile Internet Devices and simple, low-cost PC's.
enables the latest Mobile Internet Devices (MIDs), and another new category of devices for the internet called netbooks and nettops.
Delivers the power and performance you need for full Internet capabilities.
Gives you a new range of power-efficient devices with excellent performance enabled by all new hafnium-infused 45nm high-k silicon technology.
Increases energy efficiency in smaller more compact designs with a thermal design power specification ranging from less than 1W to 2.5 watts for mobile devices.
Extend battery life in select devices with an incredibly low idle and average power allowing the device to stay powered on while also conserving energy.

Dual Core Processors
What is a Dual core prossesor?
Dual-core refers to a CPU that includes two complete execution cores per physical processorIt combines two processors and their caches and cache controllers onto a single integrated circuit(silicon chip).
What is Multitasking?
Multitasking is the ability of an operating system to run more than one program simultaneously, allowing the user to easily switch and share information between applications.
How do they work together?
Since each core has its own cache, the operating system has sufficient resources to handle intensive tasks in parallel, which provides a noticeable improvement to multitasking.

CPU's
1. What is the function of the CPU?
A CPU is a complete computation engine that is fabricated on a single chip.
2. What was the name of the first CPU?
The first microprocessor was the Intel 4004, introduced in 1971.
3. Referring to the graph on page 2 of the article, describe how the speed of CPU’s has changed.
The speed o CPU's has bemome alot faster.
4. What does MIPS measure?
MIPS stands for "millions of instructions per second" and is a rough measure of the performance of a CPU.
