Networks Flashcards
What is a Network?
A network is where multiple devices are connected, it can be on a small scale or on a large scale. The internet is actually a network, it is the largest scale network currently.
Connected devices (I.e. printers, storage) can be accessed by any device connected to it. Multiple computers can connect.
But depending on the size, traffic can slow down the performance. The efficiency of the network depends on who and how someone looks after it.
What is LAN?
LAN (Local Area Network) is where computers that are in close proximity to each other. People share data through a LAN. There are normally other devices connected in a LAN such as printers or a storage device. Usually LANs require a username and password in order to access, so the correct files can be accesses.
What is WAN?
WAN (Wide Area Network) is a network that can be accessed anywhere at anytime, they still require a username and password like a LAN would. Large business use them so that employees can access data away from their place of work.
What is a MAC Address?
The MAC (Media Access Control) address is used as a network address for a computer, allowing it to connect to networks.
What are Standards?
Standards where put in place to allow computers from different countries and companies to connect and communicate.
What are Protocols?
Protocols are a set of rules that allow for devices to communicate with each other
What is TCP?
TCP (Transmission Control Protocol) - is used to prevent errors in transmissions and packet switching.
What is IP?
IP (Internet Protocol) - used to transfer all packets across the internet and routers
What is FTP?
FTP (File Transfer Protocol) - used to download and upload files
What is HTTP?
HTTP (Hypertext Transfer Protocol) - Used to transfer web pages through browsers and web servers.
What is the TCP IP stack?
TCP IP stack is the most common used protocol stack.
The IP (internet protocol) address is a unique address that is used to identify computer/devices apart in a TCP/IP network. There are two types of addresses.
Static – a permanent address
Dynamic – where the server sets the address
A wireless router is often used to connect the ips to A LARGER SERVER.
What is a Client Side Server?
Devices will be directly connected to a server. The server is normally large and contains a large amount of data, if the server goes down most of the server looses its function?
What is a Peer to Peer Server?
This is where all devices are connected to each other, There is no server in the setup. If one computer goes down, it doesn’t effect the entire setup.
What is Packet Switching?
This is where data is broken into smaller and different packages, each packet follows its own route, and can possible arrive out of sequence, but is easily put back together.
What is Circuit Switching?
A complete route between nodes is established before the data Is sent. It is a fairy outdated way of switching data.
