Open system:A system which is connected to the network and is ready for communication.Closed system:A system which is not connected to the network and can’t be communicated with.Computer Network:An interconnection of multiple devices, also known as hosts, that are connected using multiple paths for the purpose of sending/receiving data or media. Computer networks can also include multiple devices/mediums which help in the communication between two different devices; these are known as Network devices and include things such as routers, switches, hubs, and bridges. Network Topology:The layout arrangement of the different devices in a network. Common examples include: Bus, Star, Mesh, Ring, and Daisy chain. OSI:OSI stands for Open Systems Interconnection. It is a reference model that specifies standards for communications protocols and also the functionalities of each layer.Protocol:A protocol is the set of rules or algorithms which define the way how two entities can communicate across the network and there exists different protocol defined at each layer of the OSI model.

All about Computer
A computer network is a set of computers sharing resources located on or provided by network nodes. The computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies.

Each lines are attracted between two nodes, representing two IP addresses. The size of the lines is suggestive of the delay between individuals two nodes. This graph represents under 30% from the Class C systems reachable.
In 1959, Christopher Strachey filed a patent application for time-sharing and John McCarthy initiated the first project to implement time-sharing of user programs at MIT. (2)(3)(4) Stratchey passed the concept on to J.C. R. Licklider at the inaugural UNESCO Information Processing Conference in Paris that year. McCarthy was instrumental in the creation of three of the earliest time-sharing systems (Compatible Time-Sharing System in 1961, BBN Time-Sharing System in 1962, and Dartmouth Time Sharing System in 1963).
In this introduction to networking, learn how computer networks work, the architecture used to design networks, and how to keep them secure.
Network system architecture defines the physical and logical framework of the network system. It outlines how computers are organized within the network and just what jobs are allotted to individuals computers. Network architecture components include hardware, software, transmission media (wired or wireless), network topology, and communications protocols.

How do they work?
The internet is actually a network of networks that connects billions of digital devices worldwide. Standard protocols allow communication between these devices. Those protocols include hypertext transfer protocol (the ‘http’ in front of all website addresses). Internet protocol (or IP addresses) are the unique identifying numbers required of every device that accesses the internet. IP addresses are comparable to your mailing address, providing unique location information so that information can be delivered correctly.
What Is Computer Networking? – Computer networking refers to connected devices, ranging from PCs and smartphones to doorbells and thermostats, that communicate with one another.
Controller-based: Network controllers are crucial to scaling and securing networks. Controllers automate networking functions by translating business intent to device configurations, and they monitor devices continuously to help ensure performance and security. Controllers simplify operations and help organizations respond to changing business requirements.

1. Extranet: An extranet is a communication network based on the internet protocol such as Transmission Control protocol and internet protocol. It is used for information sharing. The access to the extranet is restricted to only those users who have login credentials. An extranet is the lowest level of internetworking. It can be categorized as MAN, WAN or other computer networks. An extranet cannot have a single LAN, atleast it must have one connection to the external network.

A good capacity for abstract thinking can also be required for networking, like the majority of other information technology fields. Networking typically involves a layered architecture where each layer is definitely an abstraction of services to layer above. Writing code for networking software involves a large amount of abstraction.
Internship and employment opportunities in computer networking
Simply put, computer networking is the study of how computers can be linked to share data. The concept of connecting computers dates back to the 1960s, when the Department of Defense led the first attempt to create a computer network that painstakingly linked a handful of computers around the U.S. Since then, wireless networking has taken off and networking is now considered an essential part of computing. A computer without a network, arguably, has little use in daily life.
Computer Systems and Networking
Rapid advances in computing power and networking are driving the revolution in mobile technology, video streaming and wireless networks. The computer and network track addresses the issues related to architecture, programming, and communication of computing devices, which include computers, handheld devices, and sensors. Study of computer systems involves digital design, microcomputer architecture, and high-level and assembly language programming. Computer networking deals with the design of protocols that enable multiple computers/devices to communicate effectively over a wired or wireless medium. OSU offers unique opportunities to work with faculty on advanced systems and work with internationally leading companies in this area.

Chapter 1: What is a Network?
Networks, in general, and LANs, MANs, and WANs are defined. The advantages and disadvantages of using a network are discussed.
School systems allow students to gain access to their information from connected devices through the school. Students can start a project within their classroom, save some of it on the public access part of the network, then visit the media center after school to complete the work they do. Students may also work cooperatively with the network.
Computers connected to a network are broadly categorized as servers or workstations. Servers are generally not used by humans directly, but rather run continuously to provide “services” to the other computers (and their human users) on the network. Services provided can include printing and faxing, software hosting, file storage and sharing, messaging, data storage and retrieval, complete access control (security) for the network’s resources, and many others.

President Bollinger announced that Columbia University along with many other academic institutions (sixteen, including all Ivy League universities) filed an amicus brief in the U.S. District Court for the Eastern District of New York challenging the Executive Order regarding immigrants from seven designated countries and refugees. Among other things, the brief asserts that “safety and security concerns can be addressed in a manner that is consistent with the values America has always stood for, including the free flow of ideas and people across borders and the welcoming of immigrants to our universities.”
I’m happy with our community, and would like to take this chance to strengthen our collective dedication to maintaining a wide open and collegial atmosphere. We’re fortunate to achieve the privilege to understand from each other, and also to study, work, and live together in this dynamic and vibrant place as Columbia.
