Computer networks allow devices to exchange data. There are different types of networks classified by size, such as LAN, MAN, and WAN. Networks can also be classified by transmission medium, such as wired, wireless, and hybrid. Common network topologies include bus, star, ring, mesh, and tree. Topologies describe the physical connections between nodes in a network.

For Introduction to Network
1.What is computer networking means?
2.What is network topology list three and explain brifly?
3.What is router and how it works?
4.What is the different between Hub and Switch?
Solution
1. A computer network:
It is a telecommunications network which permits computers to swap data. In computer
networks, networked computing machines exchange data with every other using a data link. The
connections between nodes are instituted using either cable media or wireless media.
2. A topology is just put; a topology is explained of a network. There are actually three basic
kinds of topologies. They are Star, Bus, and Ring. All computers and devices be connected in
series to a solitary linear cable named a trunk or occasionally called a backbone.
Star: All computers and devices are attached to a centrally placed hub or switch. The hub or
switch collects and issues the flow of data within the network. It’s improved to employ a switch
than a hub as a switch transmits the data to the future recipient rather than to every host on a
network.
Bus: every computer and device is connected in series to a solitary linear cable named a trunk or
sometimes named a backbone. Both ends of the trunk must be ended to stop the signal from
bouncing back up the cable. As the bus topology does not have a central point it is hard to
troubleshoot problems. As well, a break at any point along the bus can reason the entire network
to go down.
Ring: In this topology, every computer and device is connected to cable that forms a closed loop.
Every computer on this sort of topology acts like a repeater and boosts the signal previous to
sending it to the after that computer. It broadcasts data by passing a token around the network.
Therefore this kind of network is commonly named a token ring network. Alike to the Bus
topology, if single computer fails, the whole network goes down.
3. Routing is the procedure of forwarding IP packets as of one network to another. A router is a
device that joins networks jointly and routes traffic among them. A router will contain at least
two network cards, one actually attached to one network and the further physically connected to
another network
4. Hubs, switches, and routers are all devices that let you attach one or more computers to further
computers, networked devices, or still other networks. all has two or more connectors named
ports into which you plug in the cables to create the connection..

One way to categorize the different types of computer network designs is by their scope or scale. For historical reasons, the networking industry refers to nearly every type of design as some kind of area network. Common types of area networks are:
LAN - Local Area Network
WAN - Wide Area Network
WLAN - Wireless Local Area Network
MAN - Metropolitan Area Network
SAN - Storage Area Network, System Area Network, Server Area Network, or sometimes Small Area Network
CAN - Campus Area Network, Controller Area Network, or sometimes Cluster Area Network
PAN - Personal Area Network
LAN and WAN are the two primary and best-known categories of area networks, while the others have emerged with technology advances
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

3. Computer network
A computer network or data network is a telecommunications network which allos computerto
Exchange data in computer networks , networked computing devices Exchange data with each
other using a data link the connections between nodes are establishedusing eithercable media or
wireless media. The best-known computer network is the internet.
Network computer devices that originate, route and terminate the data are called network nodes.
Nodes can include hosts such as personal computers, phones, servers as well as networking
hardware. Two such devices can be said to be networked together when one device is able to
Exchange information with the other device, whether or not they have a direct connection to
each other.
Computer networks differ in the transmission médium used to carry their signals, the
communications protocols to organize network traffic, the network´s size, topology and
organizational intent.

4. Types
There are many classifications of networks we will focus on some of them so we have.
Depending on the size of the network, we distinguish LAN,MAN and WAN.
LAN: local área network multiple computers with limited by cables or power range wireless
antennas are connected for example network institute.
MAN: metropolitan área network. Network formed by a set of LAN networks in which computers
are connected, for example the board of Extremadura.
WAN: widw área network interconnect devices in a very large anvironment, like a country using the
telephone network.
According to the physical médium used for connection we find different types of networks based
on the physical médium used to transmit the information so we have: wireline networks that use
cables that are twisted pair and usually with RJ45 connectors, and use parallel cables to connect
the compute to the switch and crossover cables to connect computers together.

5. Inhalambricas network: the lap top connection is made via the electromagnetic waves propagating
betwee a transmitting antenna and a receiver.
Normally hybrid networks is usually LAN networks with wires but in which one of its nodes is a
wireless Access point that allows wireless conection other wireless devices.
According to network topology
Bus or liear: it has a central cable leads.
Star: all computers are connected to a hub or central hub and not connected to eachother.
Ring: all connect describing a ring, the information reaches a computer if you do not need passes
to the next.
Mesh: each computer is connected to other computers with more tan one cable.
5
6. Topologies
BUS: a bus network topology is that characterized by having a single communications channel
(called bus, backbone or backbone) to which the different diveces are connected. Thus all devices
share the same channel to communicate.
MIXED: the mixed topologies tree, star-star-star-bus, etc. Its implementation is due to the
complexity of the network solution, or the increase in the number of devices, which is necessary
to establish a topology of this kin.
ANILLO: a ring network os a network topology in which each station has a single input connection
and one output. Each station has a receiver and transmitter that serves as a translator.
DOUBLE RING: a double ring topology as its name impies insatead of just having a ring has two
conventric rinags to transmit information, where each nerwork host is connected to boch rings,
although both rings are not directly connected to each other.
6
7. TREE: the tree network is a network topology in which the nodes are arranged in a tree. From a
topological view, it is similar to a series of interconnected networks except hat star has no centarl
node. Instead, it has a trunk node, usually occupied by a hub or switch, from switch, from switch
branch the other node.
MESH: mesh topology network is a network topology in witch each node is connected to all nodes.
In this way it is posible to carry messages from one node to another by differentroutes.
TOTALLY CONNECTED: the fully connected network topology is a very effective since this fully
united all nodeshere topologies to unite them gives a totally conexa. en case one of the wirings is
reached damage of some node information shown not for others effected nodes.

9. Conclusions
-topologies used to exchange data.
-There are various types of computer network.
-A very functional analogy is to compare a network topology with the
plans of a house or building, as this tells you the exact location of each
quarter, plumbing, electricity.
-The network topology is the physical arrangement which connects a
computer network.
