This controls printers that can be connected directly to the server or (and more commonly) are connected to the network. It can control the startin and stopping of documents, as well as concepts such as spooling, printer pooling, ports, and much more.
What is Carrier Sense Multiple Access with Collision Detection (CSMA/CD)?
This governs the way that computers coexist with limited collisions, since computers on a default Ethernet LAN all share the same channel.
What is a wireless local area network (WLAN)?
This has many advantages, the most standout of which is the ability to roam.Ex) laptop
What is a database server?
This houses a relational database, one that is made up of one or more files. SQL databases fall into this category. Access databases (which are just one file) would not necessarily require a database server; they would usually be stored on a regular file server.
What is a switch?
This is a device at layer 2 that is a central connecting device for a wired network.
What is a host?
This is a device or computer that has an IP address. ex) Windows 10.
What is an Ethernet frame?
This is a group of bytes packaged by a network adapter for transmission across the network. These are created and reside on Layer 2 of the OSI model.
What is a local area network (LAN)?
This is a group of computers that are confined to a small geographical area, usually one building.
What is VLAN?
This is a group of hosts with a common set of requirements that communicate as if they were connected together in a normal fashion on one switch, regardless of their physical location.
What is a network controller?
This is a server, such as a Microsoft domain controller that oversees user accounts, computer accounts, network time, and the general well-being of the entire domain of computers and users. Also referred to as network operating systems (NOSs)
What is Ethernet?
This is a set of rules that govern the transmission of data between network adapters and various central connecting devices.
What is 802.3ab also known as?
This is also known as Gigabit Ethernet.
What is a multiport repeater?
This is also known as a hub. This is the most basic of central connecting devices (CCDs); It connects each of the computers, known as hosts, to each other by way of copper-based cables.
