Experimental Analysis of Cable Distance Effect on Signal Attenuation in Singl...
Losses during transmission and high demand of high data rate by the end users have become the biggest challenges facing the telecommunication industries worldwide with Nigeria inclusive. Fiber optic cable as a channel of communication has been adapted worldwide in solving these problems but there is a little limitation in the place of multimode fiber in long distance communication. This paper focuses on the effect of changes in distance on transmitted bandwidth on single mode and multimode fiber. Two cases were considered during this research; (a) with optical amplifier placed in between multimode fiber and (b) without optical amplifier in between multimode fiber. Readings were taken at various distances when specific bandwidth ranging from 50Mbps to 500Mbps was transmitted from the base station to the various distances and it was observed that there was no significant changes in bandwidth received at specified distances (100, 200, 300, 400, 500 etc) m when using single mode fiber, there was a drastic reduction in bandwidth when it get to a distance of 300m when using multimode. When optical amplifier was placed in between the multimode fiber at some selected distances after 400m from the transmitting BTS, it was noticed that the drastic reduction in transmitted bandwidth was almost eliminated, thereby proven that multimode fiber can be use in long distance communication provided optical amplifiers are incorporated in between the distance to bust the signal strength.

BAIT2164 Tutorial 6 (Part 2)
This document provides instructions for using class C addresses and variable-length subnet masks to create addressing schemes for multiple companies and a school system. It describes setting up subnetting for four class C networks using addresses 192.168.10.0, 222.10.150.0, 199.55.78.0, and 222.22.2.0. It also describes subnetting the school system's class B address 172.32.0.0 to assign ranges to Eastern Elementary and South High School, utilizing both the third and fourth octets to create sub-subnets.
BAIT2164 Tutorial 6 (Part 1)
Static routing has advantages of simplicity and security but lacks flexibility. It is primarily used when network traffic is predictable and stable. The four types of static routes are default, summary, standard, and fully specified routes. A default static route defines the default gateway and is used when there is no specific route. Recursive lookup occurs when a router queries other routers for routing information to reach unknown networks. The document provides questions and tasks about configuring different static route types on routers R1 and R2 based on the given network topology.
BAIT2164 Tutorial 5
Routers connect computer networks and use routing tables to determine the best path for forwarding packets between networks. They support process and fast switching to process packets, with fast switching being more efficient. Default gateways allow devices to communicate with other networks when a specific route is unknown. Router interfaces must meet criteria like having an IP address to be available. Loopback interfaces allow routers to test themselves without affecting live traffic. Routing tables contain network addresses, interfaces, and metrics to inform forwarding decisions.

This document discusses firewalls, including their role and characteristics. Firewalls establish a controlled link between an internal network and the internet to protect the internal network. There are various types of firewalls such as packet filtering, stateful inspection, application-level gateways, and circuit-level gateways. Firewalls can be located individually on hosts, or in distributed configurations with internal and external firewalls and demilitarized zones (DMZs) to host public-facing servers. Virtual private networks (VPNs) and distributed firewalls provide additional security. The document provides examples of common firewall locations and topologies used in small to large organizations.
BAIT1103 Tutorial 7
This document discusses topics related to internet security and intrusion detection systems.

It also lists past exam questions about IPSec that assess understanding of its applications, benefits, features, and use of transport and tunnel modes for authentication.
BAIT1103 Chapter 6
IPsec provides security at the IP layer by enabling encryption and authentication of IP packets. It has two modes: transport mode which secures end-to-end communication between hosts, and tunnel mode which secures traffic between security gateways. The Authentication Header (AH) provides data integrity and authentication, while the Encapsulating Security Payload (ESP) provides confidentiality through encryption. Security associations define the IP addresses and security parameters for unidirectional secure connections. Multiple security associations can be combined for added security through transport adjacency or iterated tunneling.
BAIT1103 Tutorial 5
This document provides tutorial questions and past exam questions about internet security topics including PGP, MIME, S/MIME, and email encryption. PGP provides encryption, decryption, digital signatures, and authentication for email security using algorithms like RSA and IDEA. Messages are compressed before encryption in PGP to reduce file size. MIME defines email formatting standards and has message header fields for content type, encoding, and file attachments. S/MIME provides similar functions to PGP such as encryption, signatures, and authentication over email.
BAIT1103 Chapter 5
1. PGP provides encryption, authentication, compression, and email compatibility services for securing email. It uses public key cryptography with RSA and symmetric key algorithms like CAST-128 for encryption.
2. S/MIME is an internet standard that enhances email security based on MIME and uses PKI with digital certificates and X.509 standards. It supports encrypted, signed, and signed-encrypted email to provide confidentiality and authentication.
3. Both PGP and S/MIME aim to secure email, but S/MIME is an open standard while PGP was originally independent of standards bodies.
BAIT1103 Tutorial 4
This document discusses Secure Electronic Transactions (SET) which provides a secure payment system for credit card transactions over the internet. It establishes a secure communication channel using encryption and ensures privacy through digital certificates verified by a Certificate Authority. The key participants in SET are merchants, cardholders, payment gateways and certificate authorities. Removing the Certificate Authority would compromise the system as it would no longer be able to verify the identities of other participants through digital certificates.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
