Digital logic design deals with digital circuits and how to design digital hardware using logic gates. It involves working with binary and other number systems. Binary represents information using two states (0 and 1) which can be represented electrically using voltage levels. Converting between number systems like binary, decimal, and octal allows digital components to interface. Basic logic operations like addition, subtraction and multiplication can then be performed on binary numbers.
Everything inside a computer is stored as binary numbers (strings of 0s and 1s) and processed by a CPU with millions of tiny switches that are either on or off. There are different number systems like decimal, binary, and hexadecimal used to represent numbers. Decimal is base 10, binary is base 2, and hexadecimal is base 16. A bit is the smallest unit of information (0 or 1) and bits are grouped into bytes of 8 bits to store data. Common units of data storage from small to large are bytes, kilobytes, megabytes, gigabytes, and terabytes.

8. Computing Basics
On early computers, programming was done at the digital logic
level. Programming the computer involved moving plugs and
wires.
A different hardware configuration was needed to solve every
unique problem type.
Stored-program computers have become known as von
Neumann Architecture systems.
Today’s stored-program computers have the following
characteristics:
– Three hardware systems:
• A central processing unit (CPU), A main memory system, An I/O system
– The capacity to carry out sequential instruction processing.
A single data path between the CPU and main memory.
– This single path is known as the von Neumann bottleneck.
9. Computing Basics
Non - Von Neumann model
– Newer computers now go beyond the VN model by including
specialized buses, floating-point units, and cache memories.
– Adding processors is one approach to increasing
processing power.
– Multiple Processors
• In the late 1960s, high-performance computer systems were
equipped with dual processors to increase computational
throughput.
• In the 1970s supercomputer systems were introduced with 32
processors.
• Supercomputers with 1,000 processors were built in the 1980s.
• In 1999, IBM announced its Blue Gene system containing over 1
million processors.
– Parallel processing is only one method of providing
increased computational power.
10. “1” and “0”
Towards the end of the 19th century, a mathematician
(George Boole) suggested that logical thought could be
represented through mathematical equations. Computers, as
we know them today, are implementations of Boole’s Laws of
Thought.
Boolean algebra is a mathematical system for the
manipulation of variables that can have one of two values.
– In formal logic, these values are “true” and “false.”
– In digital systems, these values are “on” and “off,” 1 and
0, or “high” and “low.”
Boolean expressions are created by performing operations
on Boolean variables.
– Common Boolean operators include AND, OR, and NOT.
11. “1” and “0”
The three simplest gates are the AND, OR,
and NOT gates.
They correspond directly to their respective
Boolean operations, as you can see by their
truth tables.
12. “1” and “0”
Combinational logic circuits
give us many useful devices.
One of the simplest is the half
adder, which finds the sum of
two bits.
We can gain some insight as to
the construction of a half adder
by looking at its truth table,
shown at the right.
14. “1” and “0” – in summary
Basic unit is a bit (1,0)
Computers are implementations of Boolean
logic.
Boolean functions are completely described by
truth tables.
Logic gates are small circuits that implement
Boolean operators.
The basic gates are AND, OR, and NOT.
The “universal gates” are NOR, and NAND.
Computer circuits consist of combinational logic
circuits and sequential logic circuits.

course
15. “1” and “0”
Decimal Numbers are based on the digits systems using
powers of 10 (base 10)
◦ 853 = 8*100 + 5*10 + 3*1
◦ 853 = 8*10^2 + 5*10^1 + 3*10^0
Computers use a binary system – powers of 2 (base 2)
◦ Cheaper and easier
◦ 1101 = 1 * 23+ 1 * 22 + 0 * 21 + 1 * 20
= 8 + 4 + 0 + 1 = 13
◦ 1001010
(1 * 26) + (0 * 25) + (0 * 24) + (1 * 23) + (0 * 22) + (1 *
21) + (0 * 20)
64 + 0 + 0 + 8 + 0 + 2 + 0 = 74
◦ What does 111 (base2) represent?
◦ How about 101 (base2)? 11101110111 (base2)?
16. “1” and “0”
With 8 bits in a byte, you can represent 256 values ranging
from 0 to 255, as shown here:
– 0 = 00000000
– 1 = 00000001
– 2 = 00000010
– 254 = 11111110
– 255 = 11111111
ASCII
– Uses 7 bits
– In the ASCII character set, each binary value between 0 and
127 is given a specific character.
– Most computers extend the ASCII character set to use the full
range of 256 characters available in a byte.
– The upper 128 characters handle special things like accented
characters from common foreign languages.
– Besides decimal, and binary, there’s hexadecimal (base 16)
17. “1” and “0”
Hexadecimal notation is simple. Just use digits for 0
through 9, and A through F for 10 through 15. The
following table shows all of the combinations.
Binary Decimal Hexadecimal Binary Decimal Hexadecimal
0000 00 0 1000 08 8
0001 01 Hexadecimal notation is simple. Just use digits

needed” and “locate, evaluate, and use
effectively the needed information…. a
survival skill in the Information Age.”
– ALA Presidential Committee on Information
Literacy. 1989
21. Evaluating Resources
Once you search:
– Did you find it?
– How long did it take?
– Were you satisfied with the answer?
– Are there other possible answers?
– What makes a resource credible?
23. Evaluating Resources
PRINT:
– Ask the following questions:
• Current edition?
• Journals peer-reviewed?
• Revision and editing process?
ONLINE:
– Ask the following questions:
• Are your online sources reliable?

• Biased domain names, such as .com or .net?
• Who is the author? Professional writer, organization,
government agency, blogger, amateur writer, fringe group,
12 year old school kid?
24. Evaluating Resources
Objectivity Issues
– Do sources reflect the question at hand or are
they writing about a related topic?
– Are they objective in presenting both sides of
the story?
– Do they provide a context for their
information?
