What is the full form of ALOHA protocol ?

ALOHA PROTOCOL:\n\nAloha, also called the Aloha method, refers to a simple communications scheme in which each source (transmitter) in a network sends data whenever there is a frame to send.  If the frame successfully reaches the destination (receiver), the next frame is sent.  If the frame fails to be received at the destination, it is sent again.  This protocol was originally developed at the University of Hawaii for use with satellite communication systems in the Pacific.\n\nIn a wireless broadcast system or a half-duplex two-way link, Aloha works perfectly.  But as networks become more complex, for example in an Ethernet system involving multiple sources and destinations in which data travels many paths at once, trouble occurs because data frames collide (conflict).  The heavier the communications volume, the worse the collision problems become.  The result is degradation of system efficiency, because when two frames collide, the data contained in both frames is lost.\n\nTo minimize the number of collisions, thereby optimizing network efficiency and increasing the number of subscribers that can use a given network, a scheme called slotted Aloha was developed.  This system employs signals called beacons that are sent at precise intervals and tell each source when the channel is clear to send a frame.  Further improvement can be realized by a more sophisticated protocol called Carrier Sense Multiple Access with Collision Detection (CSMA).\n\nIn 1070s, Norman Abram son and his colleagues at the University of Hawaii devised a new and elegant method to solve the channel allocation problem. Many researchers have extended their work since then. Although Abranson's work, called the Aloha System, used ground-based radio broadcasting, the basic idea is applicable to any system in which uncoordinated users are completing for the use of a single shared channel.

Aloha Net - One of the first functioning networks in the USA, conceived and implemented at the University of Hawaii campus at Manoa. Its purpose was to link the University mainframe computer to client computers located on outer islands at University campuses. Put in place in the early 1970s, it was dubed the Aloha Net. Key punch cards were fed through a reader, and sent over the commercial phone lines.

Interconnection, an ISO standard for worldwide communications that defines a networking framework for implementing protocols in seven layers.\n\nApplication(Layer 7) \nThis layer supports application and end-user processes. Communication partners are identified, quality of service is identified, user authentication and privacy are considered, and any constraints on data syntax are identified. Everything at this layer is application-specific. This layer provides application services for file transfers, e-mail, and other network software services. Telnet and FTP are applications that exist entirely in the application level. Tiered application architectures are part of this layer. \n\nPresentation(Layer 6) \nThis layer provides independence from differences in data representation (e.g., encryption) by translating from application to network format, and vice versa. The presentation layer works to transform data into the form that the application layer can accept. This layer formats and encrypts data to be sent across a network, providing freedom from compatibility problems. It is sometimes called the syntax layer. \n\nSession(Layer 5) This layer establishes, manages and terminates connections between applications. The session layer sets up, coordinates, and terminates conversations, exchanges, and dialogues between the applications at each end. It deals with session and connection coordination. \nTransport(Layer 4)\n This layer provides transparent transfer of data between end systems, or hosts, and is responsible for end-to-end error recovery and flow control. It ensures complete data transfer. \nNetwork(Layer 3)\n This layer provides switching and routing technologies, creating logical paths, known as virtual circuits, for transmitting data from node to node. Routing and forwarding are functions of this layer, as well as addressing, internetworking, error handling, congestion control and packet sequencing. \nData Link(Layer 2) \nAt this layer, data packets are encoded and decoded into bits. It furnishes transmission protocol knowledge and management and handles errors in the physical layer, flow control and frame synchronization. The data link layer is divided into two sublayers: The Media Access Control (MAC) layer and the Logical Link Control (LLC) layer. The MAC sublayer controls how a computer on the network gains access to the data and permission to transmit it. The LLC layer controls frame synchronization, flow control and error checking. \nPhysical(Layer 1)\n This layer conveys the bit stream - electrical impulse, light or radio signal -- through the network at the electrical and mechanical level. It provides the hardware means of sending and receiving data on a carrier, including defining cables, cards and physical aspects. Fast Ethernet, RS232, and ATM are protocols with physical layer components.

Secure Sockets Layer (SSL) and Transport Layer Security (TLS), its successor, are cryptographic protocols which provide secure communications on the Internet. There are slight differences between SSL 3.0 and TLS 1.0, but the protocol remains substantially the same. The term "SSL" as used here applies to both protocols unless clarified by context.\n\nDescription\n\nSSL provides endpoint authentication and communications privacy over the Internet using cryptography. In typical use, only the server is authenticated (i.e. its identity is ensured) while the client remains unauthenticated; mutual authentication requires public key infrastructure (or PKI) deployment to clients. The protocols allow client/server applications to communicate in a way designed to prevent eavesdropping, tampering, and message forgery.\nSSL involves a number of basic phases:\nPeer negotiation for algorithm support\nPublic key encryption-based key exchange and certificate-based authentication\nSymmetric cipher-based traffic encryption\nDuring the first phase, the client and server negotiate which cryptographic algorithms will be used. Current implementations support the following choices:\nfor public-key cryptography: RSA, Diffie-Hellman, DSA or Fortezza;\nfor symmetric ciphers: RC2, RC4, IDEA, DES, Triple DES or AES;\nfor one-way hash functions: MD5 or SHA.\n[edit]\nHow it works\n\nThe SSL protocol exchanges records; each record can be optionally compressed, encrypted and packed with a message authentication code (MAC). Each record has a content_type field that specifies which upper level protocol is being used.\nWhen the connection starts, the record level encapsulates another protocol, the handshake protocol, which has content_type 22.\nThe client sends and receives several handshake structures:\nIt sends a ClientHello message specifying the list of cipher suites, compression methods and the highest protocol version it supports. It also sends random bytes which will be used later.\nThen it receives a ServerHello, in which the server chooses the connection parameters from the choices offered by the client earlier.\nWhen the connection parameters are known, client and server exchange certificates (depending on the selected public key cipher). These certificates are currently X.509, but there's also a draft specifying the use of OpenPGP based certificates.\nThe server can request a certificate from the client, so that the connection can be mutually authenticated.\nClient and server negotiate a common secret called "master secret", possibly using the result of a Diffie-Hellman exchange, or simply encrypting a secret with a public key that is decrypted with the peer's private key. All other key data is derived from this "master secret" (and the client- and server-generated random values), which is passed through a carefully designed "Pseudo Random Function".\nTLS/SSL have a variety of security measures:\nNumbering all the records and using the sequence number in the MACs.\nUsing a message digest enhanced with a key (so only with the key can you check the MAC). This is specified in RFC 2104).\nProtection against several known attacks (including man in the middle attacks), like those involving a downgrade of the protocol to previous (less secure) versions, or weaker cipher suites.\nThe message that ends the handshake ("Finished") sends a hash of all the exchanged data seen by both parties.\nThe pseudo random function splits the input data in 2 halves and processes them with different hashing algorithms (MD5 and SHA), then XORs them together. This way it protects itself in the event that one of these algorithms is found vulnerable.\n[edit]\nApplications\n\nSSL runs on layers beneath application protocols such as HTTP, SMTP and NNTP and above the TCP transport protocol, which forms part of the TCP/IP protocol suite. While it can add security to any protocol that uses reliable connections (such as TCP), it

It's hard to know where to start on this one. this is a broad and complex topic that depends on knowledge of things like the OSI model, TCP/IP model, switching, routing, routing protocols, among others. \n\nI'll try to tackle this from a high level:\n\nThe information being transmitted includes the actual file/message, plus "headers." Headers are like instructions telling the network who is sending the file and where it needs to go. There are different types of headers for different layers of the network. \n\nThe information starts at the source computer, then goes from device to device until it finally reaches the destination computer. Along the way switches are using the Layer 2 headers to determine where to send the file, and routers are using Layer 3 headers to determine where to send the file. Once the destination computer receives the file, it strips away the headers and the computer uses the appropriate application to open the file for the intended recipient.\n\nMetaphorically speaking, it's like a letter and the post office. Someone writes a letter. They put the letter in an envelope, then put their return address on it. Then they put the destination address on it. The post office takes the letter, and they stamp all sorts of weird bar codes and lines all over the envelope, and these things tell the post office where to send the letter. Finally a postal worker at the tail end takes the letter around on his route and puts it in the right mailbox. The recipient opens the envelope and reads the letter. Neither sender nor recipient cares about the envelope or the route used, all they care about is whether the intended recipient got the letter intact.
