Vocabulary
What does NOS stand for?
Network Operating Systems
Name one advantage of a client-server model architecture.
An advantage to the client/server model is that the network is controlled centrally, making changes or additions to technology easier to incorporate.
Name one disadvantage of a client-server model.
Client/server tends to be most expensive to implement and requires a large amount of technical maintenance.
What is a common feature of a NOS?
Basic support for operating systems like protocol and processor support, hardware detection, and multiprocessing.
What is a Network Operating System?
A network operating system (NOS) is a computer operating system (OS) that is designed primarily to support workstations, personal computers, and, in some instances, older terminals that are connected to a local area network (LAN).
Name another advantage of a client-server model.
it doesn't matter if the clients and the server are built on the same operating system because data is transferred through client-server protocols that are platform-agnostic.
Name a major problem for the peer-to-peer network architecture.
There is no central server, thus files are stored on individual machines. The entire network accessibility is not in the hands of a single person. This makes it more challenging for the users to locate and find files. If the search is done through each database, the users could waste a lot of time.
What is a directory feature of a NOS?
In computer networks, a directory is a collection of users, user passwords, and, usually, information about what network resources they can access.
A local area network is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building.
Name one advantage of a peer-to-peer network.
Peer-to-peer usually works best for small to medium LANs.
Name one disadvantage of a client-server model.
An important disadvantage of the client-server model is that if too many clients simultaneously request data from the server, it may get overloaded.
Name another common feature of a NOS.
Common file system and database sharing.
What is a peer-to-peer NOS?
Peer-to-peer network operating systems allow users to share network resources saved in a common, accessible network location. In this architecture, all devices are treated equally in terms of functionality. Peer-to-peer usually works best for small to medium LANs and is cheaper to set up.
Name another advantage of a peer-to-peer network.
Peer-to-peer usually is cheaper to set up.
Name a security problem peer-to-peer networks face.
There is no security other than assigning permissions. Even if the permissions are assigned, any person with access to it will be able to log on. Some users don't even require to log on from their respective workstations.
What is an example of network security called?
user authentication and access control
What is a client-server network operating system?
Client/server network operating systems provide users with access to resources through a server. In this architecture, all functions and applications are unified under one file server that can be used to execute individual client actions regardless of physical location.
A peer-to-peer network can ______ over large distances.
share files quickly
Name a disadvantage of the centralization of a client-server model.
If any part of the network fails a lot of disruption can occur.
What is internetworking?
Internetworking is the practice of interconnecting multiple computer networks, such that any pair of hosts in the connected networks can exchange messages irrespective of their hardware-level networking technology. The resulting system of interconnected networks are called an internetwork, or simply an internet.
