v Network:
-­‐
Was
talking
about
how
to
create
a
network
(local
-­‐
global),
and
talked
about
the
component
which
you
need
to
connect
many
devices
(computer
–
server
–
mobile)
together.
-­‐ Common
physical
components
of
network:
1.Router.
2.swich.
3.PC.
-­‐
Characteristics
of
a
Network:
Speed
–
Cost
–
Security
–
Availability
–
Scalability
–
Reliability
–
Topology
-­‐ Physical
topology
categories:

4. 4
-­‐
We
model
a
network
into
different
models
to:
1.
Reduces
complexity.
2.
Standardizes
interfaces.
3.
Facilitates
modular
engineering.
4.
Ensures
interoperable
technology.
5.
Accelerates
evolution
Simplifies
teaching
and
learning.
-­‐ The
seven
layers
of
OSI
model:

5. 5
-­‐
We
have
three
classes
-­‐ Reserved
Address:
-­‐ IP
Address
range:

6. 6
-­‐
DNS
is
a
way
to
translate
human-­‐readable
names
into
IP
address.
-­‐
MAC
address
is:

7. 7
v Main
Frame:
-­‐
• Every
computer
has
a
dynamic
IP
address.
• Every
server
has
a
static
IP
address.
• Cables
used
in
network
is
UTP.
V-­‐Lan
is:
a
small
lan
inside
a
large
lan
used
for
splitting
a
one
switch
to
many
field.

8. 8
v Configuration:
-­‐
This
part
talk
about
configuring
network,
search
about
problems
and
hot
to
find
its
solution.
We
use
a
program
to
do
these
tasks
called
Performance
management.
-­‐ In
this
program
we
have
three
levels
of
problems:
1. Critical
2. Warning
3. Alarm
4. Normal
-­‐
To configure a server on a performance
requires:
1. Full computer name.
2. IP address.
3. A domain admin account.
4. Operating system.
v OS: -
- Osentication is:
1. What you know?? > “Password”
2. What you have?? > “Enter Card”
3.Who you are?? > “Such as Fingerprint”

9. 9
-­‐ Any computer consists of:
a. Software = 1. OS.
2. Programmed.
b. Hardware = 1. CPU.
2.Main menu.
3. I/O put.
4. Secondary storage.
-­‐ Types of servers:
1. File and prints server.
2. Application server.
3. Database server.
4. Domain controller server.
5. Web server.
6. E-mail server.

10. 10
v Software: -
- We have two languages format:
a. IMS:
“Information Management System”
Deals with< DB2, ADABAZ, DL/I >
b. CICS:
“Customer Information Control System”
Deals with< DB2, DL/I >
- We have two kinds of backups:
1. Full backup.
2. Incremental backup.
Transaction manager is a program from IBM Inc.
to deal with databases, provides:
-­‐ High volume.
-­‐ Low cost.
-­‐ High capacity.
-­‐ OB and DB2.

-­‐ Limited area
-­‐ Little
number of
frequencies
As same as
TETRA, But
analog.
-­‐ Cover big
area.
-­‐ Many
numbers of
frequencies.
-­‐ Types of frequency:
a. HF
3M ß à30M
Outside Egypt area
b. VHF
30M ß à300M
Inside Egypt area
c. UHF
