Robots Since the early computer, we have found new way to keep it busy by making it do some or our jobs. Along with the rapid development of computers, we have given them more complex job so that they could perform better than the humans and the previous versions of them. Along with computers, robots have been developed as well, so that they could handle the physical part of the repetitive job. These......

Storage Devices A computer is basically made of a processor, some random access memory and a hard disk device that is capable of storing data. We are going to talk about these storage devices and how many types there are. To start at the beginning, we can safely say that the first hard disk drive was too small to be taken into consideration. Only after a couple of years hard disks have started to gain in storage......

Bridges Operate In Both The Physically And The Data Link Layers Bridges operate in both the physically and the data link layers. Bridges divide a large network into smaller segments. They can also relay frames between two originally separate segments of one type. Bridges contain logic that allows them to keep the traffic for each segment separate. Bridges are repeaters that are smart enough to relay a frame only to the side of the segment containing the...... Similar Editorial : by k_buchanan32. | Source : Best Computer For The Money
Cons - Connection-oriented Network Services At the network layer, the OSI model supports two types of protocols they are Connection oriented network services and connectionless network services.A connection-oriented network services establishes a virtual circuit for the transmission of data that is active for the entire transmission. All packets belonging to a single transmission are sent, in order, over the same route, thereby allowing a...... Similar Editorial : by Jesse Miller. | Source : Wireless Network Software
Browser Architecture There are many commercial browsers that interpret and display a web document. Almost all of them use the same architecture. The browser is usually is made of three parts: controller, client programs, and interpreters. The controller gets input from the keyboard or the mouse and uses the client program to access the document. After the document has been accessed, the controller uses one of the......

Email Compatibility When PGP is used, at least part of the block to be transmitted is encrypted. If only the signature service is used, then the message digest is encrypted. If the confidentiality service is used, the message plus signature are encrypted. Thus, part or the entire resulting block consists of a stream of arbitrary 8-bit octets. However, many electronic mail systems only permit the use of blocks...... Similar Editorial : by Kathie M. Thomas. | Source : Best Computer For The Money
Simple Network Management Protocol The simple network management protocol (SNMP) provides a set of fundamental operations for monitoring and maintaining an internet. SNMP uses the concept of manager and managed devices. A few hosts are managers. To aid in monitoring, every managed device contains a combination of hardware and software called an agent, which acts as a book keeper for the host and can be accessed by a manager. Inside......

Time-division Multiplexing Asynchronous time-division multiplexing, or statistical time-division multiplexing, is designed to avoid wastage. Asynchronous means something different in multiplexing than it means in other areas of data communications.Asynchronous TDM allows a number of lower speed input lines to be multiplexed to a single higher speed line. The total speed of the input lines can be greater than the capacity of...... Similar Editorial : by A. Raymond Randall, Jr.. | Source : Best Computer For The Money
The Isdn Layers It is difficult to apply the simple seven layer architecture specified by the OSI to the ISDN. One reason is that the ISDN specifies two different channels with different functionalities. B channels are for user to user communication. D channels are predominantly for user to network signaling. The subscriber uses the D channel to connect to the network, then the B channel to send information to...... Similar Editorial : by David Peters. | Source : Buy Computer Hard Drives
Trust Processing Although PGP does not include any specification for establishing certifying authorities or for establishing trust, it does provide a convenient means of using trust, associating trust with public keys, and exploiting trust information.The basic structure is as follows. Each entry in the public key ring is a public key certificate as described in the preceding subsection. Associated with each such......

Authentication Protocols An important application area is that of mutual authentication protocols. Such protocols enable communicating parties to satisfy themselves mutually about each other`s identity and to exchange session keys.Central to the problem of authenticated key exchange are two issues confidentiality and timeliness. To prevent masquerade and to prevent comprise of session keys, essential identification and...... Source : Buy Computer Hard Drives
Broadband Isdn When the ISDN was originally designed, data rates of 64 Kbps to 1.544 Mbps were sufficient to handle all existing transmission needs. As applications using the telecommunications networks advanced, however, these rates proved inadequate to support many applications. In addition, the original bandwidths proved too narrow to carry the large numbers of concurrent signals produced by a growing......

Email Viruses A more recent development in malicious software is the Email virus. The first rapidly spreading e-mail viruses, such as Melissa made use of a Microsoft word macro embedded in an attachment. If the recipient opens the email attachment, the word macro is activated. Then the email virus sends itself to everyone on the mailing list in the user`s email package. The virus does local damage.At the end of......

Ip Security Protocols The internet community has developed application-specific security mechanisms in a number of application areas, including electronic mail, client server, web access, and others. However, users have some security concerns that cut across protocol layers.An enterprise can run a secure, private TCP/IP network by disallowing links to untrusted sites, encrypting packets that leave the premises and......

A Local Area Net Work A local area net work is usually privately owned and links the devices in a single office, building, or campus. Depending on the needs of an organization and the type of technology used, a LAN can be as simple as two PCs and a printer in someone`s or it can extend throughout a company and include voice, sound, and video peripherals. Currently, LAN size is limited to a few kilometers.LANs are...... Similar Editorial : by Joe Palladino. | Source : C++ Object
