Bits are the basic units of information in computers, represented by either 0 or 1. Bytes are groups of 8 bits that can represent 256 different values. Common prefixes are used to describe larger amounts of data storage, such as kilobytes, megabytes, and gigabytes. Hard disk drives are the primary storage location in computers, containing spinning platters coated with magnetic material. Data is organized on the platters in tracks and sectors. RAM is volatile memory that programs can directly access, while ROM contains essential startup programs. The amount of RAM affects a computer's performance and ability to run multiple programs simultaneously.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

3. Bits and Bytes
Bits -- Computers operate using
the “base-2” number system, also
known as the binary number system.
We use binary numbers because it is
easier to implement with current
electronic technology.
The word bit is short for the words “Binary
digit.”
Bits have only two possible values: 0 and 1.
Therefore, a binary number is composed of
only 0s and 1s like this: 1011.
4. Bits and Bytes
Bits are rarely seen alone in
computers. They are bundled
together in 8 bit collections called
bytes. The eight-bit byte is
something that was settled on
through trial and error over the
past 50 years.
With 8 bits in a byte (28), you can represent 256 values
ranging from 0 to 255.
You need 8 bits of information to allow enough
combinations just to cover the keys on the keyboard
5. Bits and Bytes
When you start talking about lots of bytes, you get into
prefixes like Kilo, Mega and Giga. In decimal systems, kilo
stands for 1,000, but in the binary system, a kilo is 1024 (2
to the 10th power). Technically, a kilobyte is 1024 bytes,
but it is often used loosely as a synonym for 1000. For
example, a computer that has 256K memory can store
approximately 256,000 bytes.
1.44 MB
6. CD: 700 MB
Bits and Bytes
KiloK 210 = 1, 024 thousand
Mega M 220 = 1,048,576 million
Giga G 230 = 1,073,741,824 billion
TeraT 240 = 1,099,511,627,776 trillion
Peta P 250 = 1,125,899,906,842,624
Exa E 260 = 1,152,921,504,606,846,976
Hard Drive:
DVD: 4.7 GB
30G-150G
who knows?
7. Bits and Bytes
Conversions
To convert bytes to kilobytes, divide the bytes by
1000.
To convert kilobytes to megabytes, divide the
kilobytes by 1000.
To convert megabytes to kilobytes, multiply the
megabytes by 1000.
8. Hard Disk Drives and data storage
The hard drive is where all of your programs and data
are stored. The hard drive is the most important of the
various locations of permanent storage. The hard
drive differs from other primary storage in three ways:
size (usually larger), speed (usually faster) and
permanence (usually fixed in the PC and not
removable).
9. Hard Disk Drives and data storage
The hard drive plays a significant role in the
following important aspects of the computer system:
Performance -- the speed at which the PC boots up and
programs load is directly related to hard disk speed. The
hard disk’s speed is also critical when
multitasking or when processing large
amounts of data such as graphics
work, sound and video editing,
or databases work.
10. Hard Disk Drives and data storage
Storage Capacity -- A bigger hard drive lets you store more
programs and data. The storage capacity is extremely
important when doing graphics and sound work as these
mediums use tremendous amounts of storage.
Software Support -- Newer software needs more space and
faster hard disks to load
12. Platters
A platter is a round
magnetic plate that
constitutes part of a hard
disk. Hard disks typically
contain up to a dozen
platters. Most platters
require two read/write heads, one for each side of
the platter. When the platters are not spinning,
the heads rub along the surface of the platters
until sufficient speed is gained for them to “lift
off” and float on a cushion of air.
13. Platters
While the platters and heads
are designed with the
knowledge that this contact
will occur, it still makes sense
to avoid having this contact
happen over an area of the disk where data is
stored. For this reason, most disks set aside a
special track that is designated to be where the
heads will be placed for takeoffs and landings.
14. Platters
Appropriately, this area is called the landing zone, and no
data is placed there. The process of moving the heads to
this designated area is called head parking. By having
these zones, the head does not touch the disk where data
is stored and thus prevents a loss of information
“Crashing” -- A crash can also occur if even the smallest
bit of dust makes its way onto the platter, the flight is
disrupted and the head “crashes” into the platter,
scratching it. The platters are stored in sealed containers
to prevent dust from entering. A crash
also can occur by bumping or moving
the unit while it is running.
15. Platters
The platters typically spin at 3,600
to 7,200 rpm when the drive is
operating. The arm that holds the read/
write heads is controlled by the mechanism shown in
the upper-left corner in the graphic above, which moves
the heads from the hub to the edge of the drive. The
arm on a typical hard-disk drive can move from hub to
edge and back up to 50 times per second. The purpose
of the read/write heads is to align the magnetic fields of
the particles on the platters’ surfaces; the heads read
data by detecting the polarities of particles that have
already been aligned.
16. Platters
The number of platters
and the composition of
the magnetic material
coating them determine
the capacity of the
drive. Today’s platters,
typically, are coated
with an alloy that is
about three millionths
of an inch thick.
17. Hard Drives
Tracks are concentric circles on
the surface of a disk where data
can be written. A typical floppy
disk has 80 (double-density) or
160 (high-density) tracks.
Sectors are pie-shaped wedges
on a track (dark area of
illustration.) A sector is the
smallest unit of space on the hard
disk that any software can
access. A sector contains a fixed
number of bytes (i.e. 512).
18. Hard Drives
Clusters or blocks are made up of two or more sectors.
Occasionally, the operating system marks a cluster as
being used even though it is not assigned to any file.
This is called a lost cluster.
19. Hard Drives
Disk Defragging is a process where data is relocated so that it
can be accessed more quickly thus speeding up programs.
This process is timely and should be performed over night or
when time allows.
20. RAM and ROM
RAM is an acronym for “random access memory”, a
type of computer memory that can be accessed
randomly; that is, any byte of memory can be
accessed without touching the preceding bytes.
RAM is the most common type of memory found in
computers and other devices, such as printers.
RAM is volatile, meaning that it loses its contents
when the power is turned off. In common usage, the
term RAM is synonymous with main memory, the
memory available to programs.
21. RAM and ROM
In contrast ROM (“read-only memory”) refers to special
memory used to store programs that boot the computer
and perform diagnostics.
22. RAM and ROM
RAM is the workhorse behind the
performance of your computer. It
temporarily stores information from
your operating system, applications,
and data in current use. The amount
of RAM you have determines how
many programs can be executed at one time and how
much data can be readily available to a program. It
also determines how quickly your applications
perform. The more RAM you have, the more
programs you can run smoothly and simultaneously.
