Network Vocabulary & Software Overview

2. Network Vocabulary General Terms
Node - A networked computing device that takes a protocol address andcan initiate and respond to communication from other networked devices that employ similar protocols.
File Permissions - Most file systems have methods to assignpermissions or access rights to specific users and groups of users. These systems control the ability of the users to view, change, navigate, and execute the contents of the file system.

3. Network Vocabulary (continued)
General Terms
Domain - 1. In the Internet, a portion of the spanning hierarchy tree that refers to general groupings of networks based on organization type or geography. 2. In SNA, an SSCP and the resources it controls. 3. In IS-IS, a logical set of networks.
File Transfer - Popular network application that allows files to be moved from one network device to another.

4. Network Vocabulary (continued)
General Terms
File System - Refers to the collection of system software routines that manages and accesses files located on a computer’s storage volumes.
Network Address - Network layer address referring to a logical, rather than a physical, network device. Also called a protocol address.
Network Administrator - A person who is charged with the responsibility of caring for a network and the communication abilities of its users.

5. Network Vocabulary (continued)
General Terms
Network Management - A set of activities and duties whose goal is to provide high-quality,reliable communication among a group of networked computerusers. Typical activities may include resource planning, network design, providing user assistance and training, reconfiguration ofthe network due to a change in user requirements, assessing userneeds and designing appropriate solutions and troubleshootingand remedying network problems as they arise.
Network Operator - Person who routinely monitors and controls a network, performing tasks such as reviewing and responding to traps, monitoring throughput, configuring new circuits, and resolving problems.

6. Network Vocabulary (continued)
General Terms
NFS - Network File System. A file metalanguage and set of procedurecalls to access and manage files that is standard issue on nearlyevery computer that uses TCP/IP protocols as its standard network protocols. Designed by Sun Microsystems, NFS is now astandard feature of nearly all Unix systems.
NOS - Network operating system. Generic term used to refer to what are really distributed file systems.
NTP - Network Time Protocol.

7. Network Vocabulary (continued)
General Terms
Print Spooler - A Software process that accepts a print job from a workstation as if it were a printer and then sends the print job to an actual printer at a later time. There are two styles, a background spooler, where the print spooling process is resident in the same node as the process seeking the print service, and a hardware spooler, where the print spooling process is in a separate node.
Printer Driver - In the Macintosh, a System Extension that is intermediate between the CPU and the printer. It accepts the Macintosh’s internal representation of an image and translates it into the control codes and image descriptions necessary for the printer to manufacture an image.

8. Network Vocabulary (continued)
General Terms
Time-Out - Event that occurs when one network device expects to hear from another network device within a specified period of time, but does not. The resulting time-out usually results in a retransmission of information or the dissolving of the session between the two devices.
User Account - A user account is a collection of settings and information that tells Windows which files and folders you can access, what you can do on your computer, what are your preferences, and what network resources you can access when connected to a network
Workgroup - a collection of computers that are part of the same network. All the computers are peers and do not have control over another computer. The workgroup facilitates the detection of the computers that are part of it and the sharing of resources like folders or printers. (*local accounts/policies)

9. Network Software Types of Networks (Software Management)
Windows Network (Active Directory)
Active Directory (AD) is a directory service that Microsoft developed for Windows domain networks. It is included in most Windows Server operating systems as a set of processes and services. Initially, Active Directory was only in charge of centralized domain management.
LDAP (Lightweight Directory Access Protocol) is an application protocol for querying and modifying items in directory service providers like Active Directory, which supports a form of LDAP. Short answer:  AD is a directory services database, and LDAP  is one of the protocols you can use to talk to it.

10. Network Software Types of Networks (Software Management)
Linux/Unix Network (*command line)
CH Mod - chmod is used to change the permissions of files or directories.
Usage: chmod u=rwx,g=rx,o=r myfile

Linux Network resources:
Linux Network Management Software: (*complicated, varries by distro)

11. Steps to Set up a Network (Windows)
After the hardware has been selected, purchased, installed, & configured…
Connect the computers (nodes) to the network through the appropriate medium
*Configure the node to be part of the domain to be able to access shared resources in the domain.
By default, windows PCs are part of a workgroup and will not have access to shared resources (files/printers) that are part of a managed network.
In the control panel, select the system menu and type in the name/domain of the network that you want the node to be a part of as well as the name of the computer/node (save & reboot).
Configure local policies for network groups/users to have access to the resources on the node (*gpedit.msc, right-click>properties>security)

12. Steps to Set up a Network (Windows)
On the domain server (active directory)
Create user accounts for users/groups on the network and
Create network shares (folders/files) for users to be able to access and share documents on the network
*Assign permissions to users/resources on the network (network permissions, not local)
Set up printers (*server/drivers) on the network and assign permissions

13. Viewing/Browsing Network Resources (Windows)
Open the file explorer, select the Network icon to see the nodes/resources available on the network
Right-click the network icon to display the “context menu” and select the option to “map network drive” browse to the resource that you would like to create a drive letter for and select the drive letter to assign, then click ok.
