An Overview
of
the
IBM
5110 Computing System
The vigorous competition in
today's
marketplace is a challenge
to
every
business. Despite this competition, business can
meet
this challenge through
sound management and increased productivity. Sound management and
increased productivity
of
your
company depend in part upon the efficient
handling
of
business information. For example, in order
to
make informed
business decisions businessmen require timely and accurate reports.
How
can a small business
with
a limited
staff
cope
with
such critical demands
for
information? Today the smal! business can increase its ability
to
handle
information by employing the same method larger businesses have used. You
can employ a computerized system that can be adapted
to
the
problem area(s)
of
your business. The
IBM
5110 brings the capabilities
of
a large-scale
computing system into
the
office
of
virtually every business, thereby increasing
the ability
of
your business
to
handle information.
An Overview
of
the
IBM
5110
2
The
5110
Computer is a general-purpose desktop computer designed
to
meet
the data processing requirements
of
a,
small business. Yet,
it
has the
capability, through media exchange and communications features,
to
distribute
processing in large enterprises too. This system
is
well suited
to
business and
problem-solving
applications such as:
General ledger
Accounts payable
Payroll
Accounts receivable
Financial planning
Inventory control
Order
writing/billing
Sales analysis
Cost estimating
Job
cost analysis
Linear programming
Word
processing
The
5110
performs data processing tasks
with
the speed, efficiency, and
reliability typical
of
larger computer systems.
Yet
it
is appropriate
for
small
businesses because
of:
• Physical compactness and ease
of
installation.
T~e
IBM
5110
Computer
fits
right
on
top
of
your
desk
to
give you the information you need. The
physical installation requirements are found in virtually every office
environment.
• Ease
of
operation. An experienced
computer
specialist is
not
required
to
operate the 5110. One
of
your
own
employees
who
has little
or
no
computer
experience can be trained
to
operate this system effectively.
• Application programs. These programs are made available by
IBM
to
meet
certain data processing requirements existing
within
a specific business
or
industry. Where applicable, the
IBM-supplied
application programs can
eliminate the need
for
you
to
write
your
own
programs.
Your
IBM
representative can tell you
what
application programs are available.
• Either
or
both
of
two
powerful programming languages: APL and BASIC.
APL (A Programming Language) is a
powerful
mathematical language.
It
is
particularly
well-suited
for
scientific, engineering, and research applications.
BASIC (Beginners All Purpose Symbolic Instruction Code) incorporates
QC'lclai
uu~illt::~~
i:lnu mai:nema[icai probiem-solVlng capabilities. Each
language is easy
to
learn and has inherent capabilities
that
apply directly
to
the
needs
of
business people
who
require
fast
and accurate data
processing.
• Choice
of
system options
to
meet your particular needs: magnetic tape
storage; magnetic diskette storage; printer;
I/O
adapters, both serial and
parallel; and communications adapters, asynchronous and bisynchronous.
PHYSICAL
CHARACTERISTICS
OF
THE
5110
COMPUTING
SYSTEM
The 5110 computing system consists
of
the following parts:
• A processing unit. The processing unit
is
the
arithmetic/logic
unit and the
control center
of
the system.
• A keyboard. The 5110 keyboard
is
similar
to
a standard typewriter keyboard.
In
addition, a
10-key
numeric key pad is provided
to
aid in entering
numbers. You use the keyboard
to
enter information and instructions into
the system.
• A display screen. The 5110 display screen looks like a TV screen, measures
5 inches diagonally, and contains up
to
1,024 characters
of
data. The
display screen is used by the system
to
communicate information
to
you.
• Magnetic media. The 5110 can store data and programs on magnetic tape
cartridges or diskettes. In this way, the system provides a
way
to
recall and
reuse information and programs,
without
the need
for
rekeying.
Because the tapes and diskettes are removable, the amount
of
data you can
store on the magnetic media
is
limited only by the number
of
tapes and
diskettes available.
-
Tape
storage: Various models
of
the 5110 have a
built-in
tape unit. The
tape cartridges have a storage capacity
of
204,000 characters (bytes)
of
information.
An
auxiliary tape unit can also be attached
to
the 511
Os
that
have a
built-
in tape unit.
-Diskette storage: All models
of
the 5110 can have up
to
two
diskette
units attached.
Each
diskette unit can have up
to
two
diskette drives
installed. The diskettes can have a storage capacity up
to
1.2 million
bytes. Thus, the 5110 can have a total online diskette storage capacity
up
to
4.8 million bytes.
Note: The storage capacity
of
the magnetic media is measured in bytes; 1
byte can hold 1 character
of
information.
• A printer. The printer provides printed information
from
the system.

Three general system configurations are available in the
5110
family
of
products:
• A
system
with
tape
storage
only
• A
system
with
diskette storage
only
• A
system
with
tape
and
diskette
storage
All
of
these systems can have a variety
of
input/output
options
and special
features.
The physical requirements
for
the
5110
Computing
System
are operating space
and grounded
115-volt
outlets. See Chapter
5,
Physical Planning Information
for
detailed
information
about
the
physical planning requirements.
OPERATING
CHARACTERISTICS
OF
THE
5110
COMPUTING
SYSTEM
Just
as the installation
of
the 5110 places
few
demands upon the physical
facilities
of
your
office, so
too
the operation
of
the 5110 requires no additions
to
your professional staff.
The 5110 is designed
for
the
business person
who
has little
or
no
computer
experience.
Many
operating aids are standard in the design
of
the 5110
to
eliminate any requirements
for
a computer data processing professional.
Knowledge
of
fundamental computer data processing concepts, plus training on
the 5110, is sufficient background
for
confident
operation
of
the system.
Frequently
an
employee currently responsible
for
bookkeeping
or
other clerical
duties can be expected
to
assume responsibility
for
operating
the
5110.
Some
5110
operating aids are:
• Familiar keyboard design. The 5110 keyboard features a standard
typewriter-like
arrangement. The keyboard also contains a cluster
of
10
numeric keys and calculator functions arranged like a standard adding
machine. These familiar key arrangements aid in the rapid keying
of
information.
• Keyboard function
and
command keys. The 5110 keyword and command
keys are easily identified. By using
the
keyword and command key, you can
request specific system functions and enter character combinations
with
a
single keystroke.
An Overview
of
the IBM 5110 5

• Simplified control statements. You can control the system operation
by
using
short, simple control statements. These statements, called command
statements, are composed
of
familiar, easily understandable terms and let
you avoid the highly technical control language normally used
by
a computer
system.
• Customer support functions. A comprehensive set
of
customer support
functions are provided
with
the 5110. These support functions perform
routine tasks required by every data processing system. For example, the
copy function copies selected information
from
one media
to
another, thus
allowing you extra copies
of
the information
for
audit and control purposes,
or
for
mailing
to
other locations.
• Continuous system-to-operator communications. The display screen provides
communications between you and the 5110.
As
information is keyed on the
keyboard, you can visually verify the information on the display screen.
Messages are also displayed on the display screen. These messages can
request input from the keyboard
or
identify keying errors detected by the
system.
The display screen has 16 lines
with
a total
of
1,024 character positions.
Also,
if
you
want
a group
of
people
to
view
the same information that
is
on
the
display screen, you can attach up
to
six
black-and-white
TV
monitors
to
the
5110. This allows the information on the display screen
to
be viewed on
additional screens.
gL
r========-~\..

• Magnetic storage devices. The magnetic storage media allows you
to
save
data and programs
for
later use. This means you
do
not have
to
rekey
information into the system each
time
the system is used.
Chapter
2.
Data Processing and
the
IBM
5110 Computing System
Though data processing may imply
the
presence
of
a computer,
the
term itself
describes
an
activity
that
is as old
as
commerce: performing a series
of
planned actions (processing) upon information (data)
to
achieve a desired
result. The result may be
new
information
or
the original information expressed
in a more appropriate form. For example, adding a list
of
prices
to
discover the
total cost is data processing. Preparing
an
invoice
from
a telephoned order is
also data processing.
Commercial data processing has changed
with
the demands
of
doing business.
As
long as
the
number
of
transactions
of
a business remains small, and as
long as the transactions are
of
little variety, one clerk can prepare all invoices,
keep
the
accounts receivable up
to
date, control inventory levels, and
so
on.
As
a business grows, however, its transactions become more numerous and
complex, and management often requires more information more readily in
order
to
make necessary business decisions. In
other
words, data processing
requirements have
grown
with
business. Data processing methods have had
to
change as well.
ELECTRONIC
DATA
PROCESSING
The
most
recent innovations
in
data processing methods are incorporated in
electronic data processing systems (computers). An electronic data processing
system is
an
organization
of
equipment and procedures
that
can process huge
amounts
of
data at electronic speeds. The evolution
of
such systems can be
traced
from
manual data processing methods, through
the
introduction
of
mechanical bookkeeping machines and punched card devices,
to
the computer.
Today
the
terms
electronic data processing, data processing, and computer data
processing are often used interchangeably.
INPUT, PROCESSING,
AND
OUTPUT
Though modern data processing systems have become very sophisticated,
processing data by computer and recording daily transactions by hand still
share
the
three elements fundamental
to
all data processing: input, processing,
and output.
• Input. Input is data
to
be operated on (processed).
• Processing. Processing is the handling
of
input according
to
specific
instructions
or
rules.
• Output.
Output
is the result
of
processing the input.
Data Processing and the
IBM
5110
Computing
System 7

Suppose
two
clerks are given the same problem: add all receipts
for
the last
month
to
produce a sales report.
And
suppose
that
one clerk uses
an
adding
machine and the other clerk uses a computer.
• Input.
In
our example, a record
of
the
month's
sales is the input,
whether
that
record exists in a handwritten register
or
is a data file on a magnetic
media.
• Processing. Both clerks
must
add input
to
obtain a sum, and both the
adding machine and
the
computer
must
operate according
to
the rules
of
addition and be used
to
achieve specific results
for
a particular job.
• Output. The
output
in our example is a sum
that
represents sales revenue,
whether
the sum is presented in a
hand-drawn
chart
or
a report printed by
the
computer.

5110 DATA PROCESSING
Input
The
fundamental
data processing
concept
(input, processing, and output) is
reflected
in
every
computer
system.
Processing
Unit
(Processing)
Magnetic Tape
(Input
and
Output)
Magnetic Diskette
(Input
and
Output)
Every
computer
must
provide some
way
to
get
information
(input)
into
the
system
for
processing. On
the
5110, input can be entered
from
the
keyboard
or
read
from
the
magnetic media.
To
write
orders,
for
example,
the
operator
can
enter
order
information
for
immediate processing
or
place it on
an
appropriate magnetic storage media where
it
is stored until required.
If
orders are
to
be processed immediately, processing begins as soon as
the
operator enters enough data
for
the
5110
to
begin processing an order. The
system processes additional data
as
it is entered. This
method
of
processing,
whereby
the
system continuously processes
the
data
for
a
job
as
the
operator
enters
the
data, is called interactive processing.
On
the
other
hand,
the
operator can prepare all
the
data required
for
a
particular
group
of
orders, record
the
data on one
of
the
various magnetic
media, and then
instruct
the
5110
to
read
the
data and prepare all
the
orders
at once. This
method
of
processing,
whereby
all
the
data
for
a
job
is
submitted
in a single group,
or
batch, is called batch processing.
Data
Processing
and
the
IBM
5110
Computing
System
9
10
Processing
Every
computer
has a processing unit. The processing
unit
controls
the
system
and manipulates data.
It
monitors
the
flow
of
information
into
the
system,
performs
calculations and
other
operations
on data, and regulates
the
flow
of
output.
But
the
processing
unit
must
be
told
exactly
where
to
find
input,
how
to
operate on input, and
what
to
do
with
output.
Such directions are given
to
the
processing
unit
in
the
form
of
computer
programs. A
computer
program
is a
sequence
of
precise
instructions
written
in a special
form
that
the
computer
can interpret. Before a
computer
performs
any data processing,
-a
program
explaining
where
to
find
input,
how
to
operate on
the
input, and
what
to
do
with
output
is read
into
the
processing unit.
Programs are read
into
an area
of
the
processing
unit
known
as main storage.
Main
storage is
the
processing
unit's
work
area. Input, programs, and
output
are
moved
in and
out
of
main
storage
in
whatever
manner
each particular data
processing
job
requires.
Application
Program
Anapplicatiom
program
specifies
distinct
operations
to
be
performed
on
specific
input
to
obtain unique
output.
A
program
directing a
computer
to
update
accounts receivable
according
to
input
provided
by
the
operator
is an
example
of
an application program. A
program
instructing a
computer
to
print
a sales
report
based on a particular transaction file is another example
of
an
application program. In
other
words,
application
programs
operate
directly
on
data
to
meet
specific data processing requirements.
Application
programs
are
written
in one
of
the
5110
programming
languages, BASIC
or
APL.
Output
Every
computer
system
must
include
some
means
of
providing
output.
The
5110
can store
output
on a
tape
or
diskette,
display
output
on
the
display
screen,
or
print
output.
You
can
print
output
in
the
format
best
"Suited
to
each application.
The
5110
can,
for
instance,
print
on
forms
of
different
kinds and sizes, such as
paychecks and invoices. The
5110
can also
print
different
kinds
of
reports,
such as
cost
analysis reports and sales reports.
ADVANTAGES OF 5110
COMPUTER
DATA
PROCESSING
If
data processing is always a matter
of
input, processing, and output,
how
is
the 5110 Computer data processing different from manual or mechanical data
processing? Computers process large volumes
of
data faster, more accurately,
in less space, and
with
greater versatility.
•
Speed.
Because computers process data electronically, they operate
at
remarkable speeds
that
save a tremendous amount
of
time. The 5110 can
read over 3,000 128-character records
from
a diskette
to
main storage in
about one minute, and can print reports at rates up
to
120
characters per
second.
•
Accuracy.
A computer does exactly
what
it
is
told
to
do
and only
what
it
is
told
to
do. Because
of
this constant dependence on instructions, the 5110
Computer
follows
program after program, second after second, hour after
hour,
with
unvarying accuracy.
The
5110
Computer can also reduce transcription errors by dramatically
reducing the need
for
manual transcription. Once your operator records data
on
the magnetic media, that data may never have
to
be
written
by hand
again; you can update
as
many different files, complete
as
many different
kinds
of
forms, and create
as
many
different
reports
from
that data
as
you
have application programs that use the data. By referring
to
the display
screen while
first
recording the data, you can ensure
that
the data is keyed
correctly. And application programs

• Versatility. The number of different tasks the
5110
can
do
is
limited only
by
the number of different programs
run
on
it.
The
5110
Computer
can
do
much more than just add, subtract, multiply,
and
divide. The
5110
can,
for
example, prepare invoices, keep accounts receivable
up
to date, print weekly
paychecks, analyze data for thorough cost
and
sales analysis, prepare
estimates, and
so
on.
Speed, accuracy, data compression, and versatility combine to reduce data
processing errors and increase productivity. But a
less
obvious advantage of
computers
has
a more fundamentel effect.
Data
Processing
and the
IBM
5110
Computing System 13
14
Computers impose discipline. As explained, a computer is helpless
without
programs;
it
cannot
think
for
itself. Neither can a
computer
guess
whether
its
programs really reflect
the
problems at hand; you
must
see
that
they do. In
other
words, you
must
carefully analyze
the
data processing requirements
of
your
organization in order
to
take full advantage
of
a computer. For instance,
with
the data processing capabilities a
5110
Computing System provides,
what
additional cost analysis, inventory control, and auditing procedures
would
you
like
to
implement in
your
organization?
The responsibility
for
analyzing
an
organization's data processing requirements
falls,
of
course,
to
management. But the discipline imposed by a
computer
extends throughout
the
data processing activities
of
the
organization. ,Once
you've
designed
or
selected 5110 programs
that
reflect management
directions, you've established management control
that
is automatically
practiced each
time
those programs are used.
