Object-Oriented Programming (OOP) a Quick Note from Steve Jobs

If you're an Apple fan boy/girl, you might be interested in what Steve Jobs had to say about Object-Oriented Programming. This is an excerpt from a 1994 Rolling Stone interview where Steve (not a programmer) explains OOP in simple terms

---

Jeff Goodell: Would you explain, in simple terms, exactly what object-oriented software is?

Steve Jobs: Objects are like people. They’re living, breathing things that have knowledge inside them about how to do things and have memory inside them so they can remember things. And rather than interacting with them at a very low level, you interact with them at a very high level of abstraction, like we’re doing right here.

Here’s an example: If I’m your laundry object, you can give me your dirty clothes and send me a message that says, “Can you get my clothes laundered, please.” I happen to know where the best laundry place in San Francisco is. And I speak English, and I have dollars in my pockets. So I go out and hail a taxicab and tell the driver to take me to this place in San Francisco. I go get your clothes laundered, I jump back in the cab, I get back here. I give you your clean clothes and say, “Here are your clean clothes.”

You have no idea how I did that. You have no knowledge of the laundry place. Maybe you speak French, and you can’t even hail a taxi. You can’t pay for one, you don’t have dollars in your pocket. Yet, I knew how to do all of that. And you didn’t have to know any of it. All that complexity was hidden inside of me, and we were able to interact at a very high level of abstraction. That’s what objects are. They encapsulate complexity, and the interfaces to that complexity are high level.

Intrusion Detection System (IDS)

An intrusion detection system (IDS) is a system that monitors network traffic for suspicious activity and issues alerts when such activity is discovered.

Network Topology

A network topology is the arrangement of a network, including its nodes and connecting lines. There are two ways of defining network geometry: the physical topology and the logical (or signal) topology.

The most common nodes are computers and peripheral devices. Network topology is illustrated by showing these nodes and their connections using cables. There are a number of different types of network topologies, including point-to-point, bus, star, ring, mesh, tree and hybrid. 


 

Authentication

Authentication is the process of determining whether someone or something is who or what it is declared to be. To access most technology services of Indiana University, you must provide such proof of identity. Services such as the Central Authentication Service (CAS), Active Directory, and Duo provide this functionality for most major systems and applications at IU.

In private and public computer networks (including the internet), authentication is commonly done through the use of login passwords or passphrases; knowledge of such is assumed to guarantee that the user is authentic. Thus, when you are asked to "authenticate" to a system, it usually means that you enter your username and/or password for that system.
Additional forms of authentication, commonly referred to as two-factor or multifactor authentication, may be layered on top of login credentials. Typically, these methods use a physical token, such as a card or device, to increase security.
