Tournament System Axiom 1: Every game consists of two players. Axiom 2: For every distinct
pair of players, p and p, there is exactly one game. Axiom 3: There are exactly M players. a.
What are the undefined terms? b. How many games will there be? c. Is the system consistent?
(Show a model for M = 5. Explain what happens each time M increases by 1. 3 points.) d. Is the
system independent? (Your answer requires proof. 3 points.)
Solution
An axiomatic system is a list of undefined terms together with a list of statements (called
“axioms”) that
are presupposed to be “true.” A theorem is any statement that can be proven using logical
deduction
from the axioms.
a.Undefined terms: Games and players
b.Number of games: M-1 (as there are 1 less game than the number of player if they play each
other once)
c.Independence: An axiom is called independent if it cannot be proven from the other axioms. In
other words, the axiom “needs” to be there, since you can’t get it as a theorem if you leave it out.
How do you prove that
something can’t be proved? This relates to the area of mathematics known as logic.
d.Consistency:- If there is a model for an axiomatic system, then the system is called consistent.
Otherwise, the system is inconsistent. In order to prove that a system is consistent, all we need to
do is come up with a model:
a definition of the undefined terms where the axioms are all true. In order to prove that a system
is
inconsistent, we have to somehow prove that no such model exists
For M=5 there are exactly 4 games should be played. Hence there is consistency in the
system.Since this is a definition of the undefined terms where the axioms are all true.

ICT includes any product that will store, retrieve, manipulate, transmit, or receive information electronically in a digital form. For example, Computers, digital T.V, E-mails, and many more.
Abacus and the printing press are examples of ICT, the term usually refers to modern technology based on electronics.
ICT combines the technology of computing and telecommunications so that a large amount of data can be stored and transmitted.
Televisions, computers, satellites, and telephones are just some of the types of equipment used in ICT.
Unguided Media in Computer Network Advantages and Disadvantages Edifyclue.in.pdfsunil shukla
Unguided Media
Unguided media is also known as wireless communication. It does not require any physical medium to transmit any electromagnetic signals.
Medium media transmits electromagnetic signals through the air to all. These signals are available to anyone who has a device capable of receiving those signals.
Signals go from transmitter to beneficiary by means of a way. this path called the media can be guided media or unguided media.
A guided media is contained within physical boundaries, while an unguided media is boundless.
It is also known as unbounded media and does not have any specific limits. All this allows the user to stay connected at all times.
Because the communication done by it is wireless, the user can connect himself anywhere on the network. It is also classified into three radio waves, microwave, and infrared waves.
Computer Hardware And Software Types, Functions, Difference between Hardware ...sunil shukla
Computer Software
We are already aware that computers need instructions to carry out the tasks, and they cannot perform themselves without any instructions.
When instructions are given to computers in a manner that computers can understand them and execute those instructions accordingly.
Such instructions to carry out certain tasks or tasks that are predesigned when made available in a computer-readable format are called programs. Such programs are called computer software.
This software can be stored in secondary storage devices such as (hard disks, cd-rom, etc) and make use of them as and when required.
Software is a set of programs that can be stored on a medium that is used to get the job done.
It plays an important and crucial role in all computer systems by creating a connection or bridge between the user and computer hardware.
The software needs to be checked before being used. There are some terms that are used for the process of accessing software including starting, executing, running, opening, and others.
Computer Hardware
Let’s understand this in easy language, Hardware is the physical and touchable parts of a computer means you can touch those components.
Internal hardware parts of a computer are known as components and external hardware parts of a computer are called peripherals both of them are known as computer hardware.
In both PCs or desktop computers, the components of hardware are the same but there is a big difference in the size of the hardware.
Computers can only operate or start when both software and hardware are present and work together in the system, there is no chance to start a computer only with software or hardware.
You can enter the operating system by using operating software where hardware helps the operating software to perform fast and easily.
What is Keyboard Different Types of Keyboards Advantages, and Disadvantages.pdfsunil shukla
We already discussed that this is the main input device used to give the command to the computer.
The primary function of this is to act as an input device by using this, users are able to type documents, use different key shortcuts, play games, and many other tasks.
The inspiration for keyboard design is taken from the typewriter.
In simple words, A keyboard is an input device that contains keys and is used to enter data into your computer.
A desktop computer usually has 100 to 105 keys, but this is not fixed some small computers like notebook computers have fewer keys than normal PCs.
Full-Form of Keyboard
According to Fullformhub.com there is no full form of keyboard is present, but some people named this word as an acronym with a different meanings, most common full form of Keyboard is:
K – Keys
E – Electronic
Y – Yet
B – Board
O – Operating
A – A to Z
R – Response
D – Directly
Different Types of keyboards Keys
ABCDE, XPERT, QWERTZ, AZERTY, and QWERTY are the different types of keyboard keys layout.
This headline is based on how keys are organized on the keyboard because the keys are divided into too many sections for making the user experience faster.
Keys Layout of a Qwerty Keyboard
Alphanumeric keys: Alphanumeric are divided into two parts, alphabets, and number keys and this includes letters, numbers, punctuation, and symbol keys.
Function keys: This is located o the top of the board, there are a total of 12 function keys used to perform specific tasks, like F1 displays a help window and F5 used to refresh window or any browser same as all 12 keys have their own work to perform.
Control keys: Control keys are used to perform different work examples of control keys are Ctrl, Alt key, Window logo key, and Esc. these keys are used alone or with other function keys.
Numeric Keypad: This is located on the right side of a keyboard. The arrangement of all numeric keys is very similar to calculators that included numbers, decimals, and many other keys. this is the most recent invention, to enhance the user experience.
Navigation keys: These keys are just touching with the numeric keys which include Arrow keys, page up and down keys, delete keys, home, and insert keys.
This is the basic key layout but in some cases, there are different types of layouts present. Your keyboard layout must be a different type.
Why do we have two ctrl, alt, and shift keys?
All the keys present on the keyboard are made to increase our effectiveness and work performance.
At the start, there are only one ctrl, alt, and shift key, but when the makers identified the problem of users they add dual keys.
This is done because when you want to type “A” you will use your right hand to press the shift same as when you want to type “L” you will use your left hand to press shift, this will help the pro users to enhance their productivity. It also increases the life of some most used keys.

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
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Router
In this article, you are going to read about what is router and the types of
routers. A Network router is a Hardware Networking Device, Which is used to
connect the network.
The Router then receives the Packet data, and forwards the Destination Device
after analyzing any hidden information in the Data Packet.
This Networking Device is used to connect different networks Wire or
Wirelessly. We also use it at home, which we call Wireless Router. Which you
access the Internet.
Types of Routers
Below are the different types of Router:
● Wireless router
● Wired router
● Edge Router
● Core Router
● Virtual Router
Wireless router – It can exist at a library, home or railway station, or even
elsewhere, it creates a wireless signal.
If you are in the library, we can connect to the internet using a wireless signal
because your laptop is within limits. We keep the user ID and password for the
security of the router.
3. When we try to connect to the router, it will ask for a password and UserId.
UserId and password come with the device. Due to security, no information
about the user is harmed.
When we go to public places, we can see that there will be a Wi-Fi window
ready to use the Internet on our phones, and we can see that it is password
protected. Wireless routers are publicly available. N number of users can
connect to it.
Wired router – We need a wire to connect to the network. If we go to a bank
or small college, or office, we can see that a PC or laptop is connected to the
Internet using an Ethernet cable, and it is a wired router.
IF a user wants to connect to the phone, they can use VOIP (voice-over IP
technology). There is an ADSL (modem) that has two jacks for connecting to
Ethernet and mobile phones
Edge Router – It can be wired or wireless and distribute Internet data
packets between one or more networks. But it does not distribute Internet
data packets within the network.
Core Router – It is designed to operate in the Internetwork or core. This
core supports multiple telecommunications interfaces of maximum speed and
usage on the Internet.
It can forward IP packets at full speed on all of them. It supports the routing
protocol used in the core. It will distribute Internet data packets within the
network. But the Internet will not distribute data packets between core
networks.
4. Virtual Router – Virtual network routers operate according to redundancy
protocol (VRRP); It becomes active when the main or primary router fails or
becomes inactive.
It takes multiple routers in a group so that they can share a virtual IP address.
It has a master for each group that handles IP packets. If the master fails while
forwarding the packet, other routers will take a position.
Use of router
● Routers are used to connect hardware equipment to remote
location networks such as BSC, MGW, IN, SGSN, and other
servers.
● This significantly speeds up the rate of data transmission as it
uses a high STM (Synchronous Transport Module) link for
connectivity; hence it is used in both wired and wireless
communication.
● Internet service providers widely use routers to send data from
source to destination in the form of e-mail, web pages, images,
voice, or video files. Moreover, it sends data all over the world
with the help of the network IP address of the destination.
● Network routers are also used by software testers for WAN
communication. For example, the software manager of an
organization is located in Agra, and its executive is located at
some other place like Pune or Bangalore. It then provides a
method for the network router executive to share their software
tools and other applications with the manager with the help of
the router by connecting their computer system to the router
using the WAN architecture.
● In wireless networks, after the VPN is configured in the network
router, it can be used in a client-server model, which allows
sharing of Internetwork, video, data, and hardware resources.
5. ● The router also has the facility of an inbuilt USB port. and has
sufficient internal storage capacity. External storage devices can
be used with routers to store data.
● Network routers are used to set up an organization’s operation
and maintenance center, which is known as a NOC center. In
large configurations, routers are connected by optical cables at a
central location.
How router can help your
business?
A common device for modern network computing, a router connects both
employees and the Internet to the network, where almost every essential
business activity takes place. Without routers, we would not be able to
collaborate, communicate or use the Internet to collect and learn information.
These routers also provide security. Embedded firewall and content filtering
software provide additional protection from unwanted content and malicious
websites without affecting your online experience.
However, routers are not just made for data transmission or internet
connection. Most network routers also allow you to connect hard drives and
use them as file-sharing, servers, or printers, which anyone can access on the
network.
Which OSI layer does the router
work on?
The network Router works on the Network Layer in layer 7 of the OSI Model.
This device is made up of a router, hardware, and software.
6. It has an Internetwork Operating System, CPU, Memory Storage, and some
I/O Ports. It does not have Operating System like Windows or MAC.
The routing Algorithm and Routing Table are stored in Storage Memory.
Through the Routing Algorithm and Routing Table, it is found out that the
Input Packet has been received. Which network or which device to send that
packet.
How router work
As we know that Network Router works to forward the Data Packet from one
network to another.
Its main function is to receive the data packet and Deliver the Receiver is hot.
You sent a Facebook message from your computer to your friend, who is
currently in Delhi.
First, the message is converted into a packet and reaches the nearest router.
Now it checks the Routing Table from the Routing Protocol.
The routing table has the address and path distance of all the nearby network
routers. Then the data packet is forwarded to the nearest Router, in which the
IP address of the Receiver is kept.
As soon as the packet reaches the next router, it again checks the shortest path
and is sent to the next router. In this way, the Packet is able to reach the
Receiver's Computer.
A network Router connects a lot of networks and maintains its Routing table.
maintain means update.
7. Each Router has the knowledge of the Router around him. Routing Protocol
resides in all routers, with the help of which they talk among themselves.
And along with this, share your connected networks’ information among
themselves and update the routing table. This is how this Networking Device
works.
