Store-and-Forward
Store-and-forward is a telecommunications technique in which information is sent to an intermediate station where it is kept and sent at a later time to the final destination or to another intermediate station.

Split Horizon
A split horizon is an algorithm used to prevent routing loops in distance-vector routing protocols by prohibiting a router from advertising a route back onto the interface from which it was learned.

Sub Network
A sub network is a separately identifiable part of a larger network that typically represents a certain limited number of host computers, the hosts in a building or geographic area, or the hosts on an individual local area network.

Star Network
Star networks are one of the most common computer network topologies. A star network consists of one central switch, hub or computer, which acts as a conduit to transmit messages. This consists of a central node, to which all other nodes are connected. The central node provides a common connection point for all nodes through a hub.

Socks
Socket secure (socks) is an internet protocol that routes network or data packets between a client and server through a proxy server. Socks ensures proper authentication of users and allows authorized users only to access a server. Socks uses sockets to represent and keep track of individual connections. The client side of socks is built into certain web browsers and the server side can be added to a proxy server.

Symmetric Cryptography
Symmetric cryptography is a branch of cryptography involving algorithms that use symmetrical keys for two different steps of the algorithm. Symmetric cryptography is called secret-key cryptography because the entities that share the key.

Subnet Mask
A subnet mask is used to determine the number of bits that are used for the subnet and host portions of the address. It is used as a screen of numbers used for routing traffic within a subnet. Once a packet has arrived at a gateway or connection point with its unique network number, it can be routed to its destination within the internal gateways using the subnet number.

Stream Cipher
A stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream. In a stream cipher, each plaintext digit is encrypted one at a time with the corresponding digit of the keystream, to give a digit of the ciphertext stream.

Spam
Spam is the term used for flooding the internet with many copies of the same message, in an attempt to force the message on individuals who would not otherwise choose to receive it. Most spam mails or messages are commercial advertising, often for dubious products, get-rich-quick schemes, or quasi-legal services.
