Networking
Types of networks
VLAN
Virtual Local Area Network (local area network with a definition that maps workstations on some other basis than geographic location)
-
WAN
Wide Area Network (connect multiple smaller networks, such as local area networks (LANs)
SAN
is a dedicated high-speed network that interconnects and presents shared pools of storage devices to multiple
-
RAID
is a way of storing the same data in different places on multiple hard disks or SSDs to protect data in the case of a drive failure
Protocols
TCP
which uses a set of rules to exchange messages with other internet points at the information packet level
UDP
is used to establish low-latency and loss-tolerating connections between applications and the Internet.

Connection types
Wireless Technologies
Wireless technology refers to technology that allows us to communicate without using cables or wires
-
Microwave - Microwave is a line-of-sight wireless communication technology that uses high-frequency beams of radio waves to provide high-speed wireless connections that can send and receive voice, video, and data information
Bluetooth - a short-range wireless communications technology to replace the cables connecting electronic devices, allowing a person to have a phone conversation via a headset, use a wireless mouse and synchronize information from a mobile phone to a PC, all using the same core system.
Cable
Network cables are used to connect and transfer data and information between computers, routers, switches and storage area networks
Optical fibre
Fiber optics, or optical fiber, refers to the medium and the technology associated with the transmission of information. Fiber optics is usually used for long distance and high performance data networking
Data Centres
Centralized locations where there is computers only to collect, store and process data.
-
Bandwidth/Bit rates
Bit rates- number of bits per second that can be transmitted. Higher bit rate could mean quicker loading speeds and better quality
-
peer-to-peer (P2P)
Computer systems which are connected to each other through the internet, files can be shared easily. Each computer on P2P network acts as a client and server. There is no central server
Synchronous
A synchronous network is one where data is transmitted and received at the same time. Data is simultaneously transferred in both directions. Synchronization is accomplished with a signal clock.
Asynchronous
Data flows in only one direction at a time, and there is no signal clock used
Physical Security
Physical security - is the protection of personnel, hardware, software, networks, and data from physical actions and events that could cause serious loss or damage to an enterprise.
