Introduction
A network consists of two or more computers that are linked in order to share resources (such as printers and CD-ROMs), exchange files, or allow electronic communications. The computers on a network may be linked through Lan/Fiber optics cables, telephone lines, radio linked, satellites, Wi-Fi, Bluetooth, VPN or infrared light beams.
In summary, all networks must have the following:
- Something to share (data)
- A physical pathway (transmission media)
- Rules of communication (Protocol)
The goal of computer networking is to provide services and to reduce equipment costs. Networks enable computers to share their resource by offering services to other computers. Some of the primary reasons for networking PCs are as follows:
- Share files
- Share printers and other devices
- Enable common administration and security.
- Supporting network applications such as electronic mail and database service.
To have a network you typically have four things (besides the computers themselves):
- Network Interface Cards (NICs) – cards that plugs into the back (or side) of your computers and lets them send and receive messages from other computers
- Network Media – the medium to connect all of the computers together
- Hub/Switch – hardware to perform traffic control
- Protocol – a set of communication rules to make sure that everyone speaks the same language
How Does a Network Work?
How does one computer send information to another? It is actually rather simple. The diagram below shows a simple network:
If Computer A wants to send a file to Computer B, the following would take place:
Based on a protocol that both computers use, the NIC in Computer A translates the file (which consists of binary data — 1’s and 0’s) into pulses of electricity.
- The pulses of electricity pass through the cable with a minimum (hopefully) of resistance.
- The hub takes in the electric pulses and shoots them out to all of the other cables.
- Computer B’s NIC interprets the pulses and decides if the message is for it or not. In this case, it is, so, Computer B’s NIC translates the pulses back into the 1’s and 0’s that make up the file.
The pulses of electricity pass through the cable with a minimum (hopefully) of resistance.
The hub takes in the electric pulses and shoots them out to all of the other cables.
Computer B’s NIC interprets the pulses and decides if the message is for it or not. In this case, it is, so, Computer B’s NIC translates the pulses back into the 1’s and 0’s that make up the file.
Sounds easy, however, if anything untoward happen, along the way, you have a problem, not a network. So, if Computer A sends the message to the network using NetBEUI, a Microsoft protocol, but Computer B only understands the TCP/IP protocol, it will not understand the message, no matter how many times Computer A sends it. Computer B also won’t get the
Message if the cable is getting interference from the fluorescent lights . . . or if the network card has decided not to turn on today . . . etc. etc.
Objectives
- The connection to the Internet
- Networking math
Requirements for Internet Connection
- Connection to the Internet can be broken down into the following:
- Physical connection
- Used to transfer signals between PCs within the local network and to remote devices on the Internet
- Logical connection
- Uses standards called protocols. A protocol is a formal description of a set of rules and conventions that govern how devices on a network communicate.
- The application
- Interprets the data and displays the information in an understandable form
PC Basics
- Electronic components
- Connector, IC, LED, resistor, transistor
- Personal computer subsystems
- Bus, CD-ROM drive, CPU, disk drives, microprocessor, motherboard, RAM, ROM
- Back plane components
- Mouse port, network card, parallel port
All Computers Have a CPU, Memory, Storage, and Interface
Network Interface Cards
When you select a network card, consider the following three factors:
- Type of network
- Type of media
- Type of system bus
NIC and Modem Installation
- Connectivity to the Internet requires an adapter card, which may be a modem or NIC.
- Notebook computers may have a built-in interface or use a Personal Computer Memory Card International Association (PCMCIA) card. Desktop systems may use an internal or external NIC.
Modem
- A modem, or modulator-demodulator, is a device that provides the computer with connectivity to a telephone line
- A modem converts data from a digital signal to an analog signal that is compatible with a standard phone line
- The modem at the receiving end demodulates the signal, which converts it back to digital.
TCP/IP Description and Configuration
- Transmission Control Protocol/Internet Protocol (TCP/IP) is a set of protocols or rules developed to allow cooperating computers to share resources across a network.
- To enable TCP/IP on the workstation, it must be configured using the operating system tools.
- Ping is a program that is useful for reifying a successful TCP/IP installation.
- It works by sending multiple IP packets to a specified destination.
- Each packet sent is a request for a reply. Each reply contains the success ratio and round-trip time to the destination.

The most devastating genocide in the world is being carried out by the follwoing :
1- AIPAC, brows ( https://www.youtube.com/watch?v=COx-t-Mk6UA ).
2- Miriam Adelson brows https://www.youtube.com/watch?v=Nr0LkA7VW7Q.

4-The Evangelical Church,
Which kill innocent women and children in Gaza.
AIPAC ( https://www.youtube.com/watch?v=COx-t-Mk6UA ) and the Evangelical Church are implicated in one of the most devastating genocides in history, targeting innocent women and children in Gaza.
These organizations have provided Israel with explosives to enable their genocidal actions.
Gaza has been declared a disaster zone, severely lacking in vital resources necessary for survival.
AIPAC, The Evangelical Church, Miriam Adelson, Elon Musk, and timothy mellon and America tax payer,, and Israel have ravaged 90% of Gaza, leading to the destruction of 437,600 homes and the loss of one million lives, including 50,000 individuals currently trapped under rubble, with 80% of the casualties being women and children.
They have also destroyed 330,000 meters of water pipelines, leaving the population without access to potable water.
Furthermore, over 655,000 meters of underground sewage systems have been devastated, depriving residents of essential sanitation facilities.
The destruction encompasses 2,800,000 meters of roadways, making transportation impossible for the affected population.
Additionally, 3,680 kilometers of the electrical grid have been dismantled, resulting in widespread power outages.
The assault has led to the demolition of 48 hospitals, eliminating crucial healthcare facilities for those in need.
Moreover, the actions of AIPAC, The Evangelical Church, Miriam Adelson, Elon Musk, and timothy mellon and America tax payer,, and Israel have disrupted the education of over 785,000 students, with 494 schools and universities being completely destroyed, many as a result of aerial bombardments.
They have also targeted 981 mosques, effectively suppressing the prayers of the homeless who seek divine assistance.
Consequently, over 39,000 young children have been left orphaned, lacking parents or guardians to provide care.
It is important to highlight that the historical context of warfare has never seen a situation where 80% of a nation has been devastated, 100% of its population has been displaced, and 50% of the casualties are children.
Recognizing the seriousness of this situation is imperative.
Organizations such as AIPAC and the Evangelical Church in America are contributing to what can only be characterized as genocide.

The implications of American taxpayer funding in relation to Israel’s actions against innocent children are concerning.
1. A thorough examination of Israel’s precarious circumstances is necessary.

Laws of jews Taurãt (Torah) wich is a part of the Bible
We ordained in Taurãt for them: “A life for a life, an eye for an eye, a nose for a nose, an ear for an ear, a tooth for a tooth and for a wound an equal retaliation.”
The Torah, which is part of the Bible, has commanded that the same be done to the Jews. The order of the Torah, which is part of the Bible, is to immediately kill any Jew you see on the street. Since the Jews in Gaza have also killed women and children, you should kill any Jews – men, women, and children – as soon as you see them, whether on the street or anywhere else. And because they have killed everyone in Gaza without mercy, you must do the same to them. If you carry out these actions, you will be following the order of the Torah, which is part of the Bible, and you will be rewarded by going to heaven.
