computer network, or data network, is a digital telecommunications network

Repeaters and hubs

A repeater is an electronic device that receives a network signal, cleans it of unnecessary noise and regenerates it. The signal is retransmitted at a higher power level, or to the other side of an obstruction, so that the signal can cover longer distances without degradation. In most twisted pair Ethernet configurations, repeaters are required for cable that runs longer than 100 meters. With fiber optics, repeaters can be tens or even hundreds of kilometers apart.

A repeater with multiple ports is known as an Ethernet hub. Repeaters work on the physical layer of the OSI model. Repeaters require a small amount of time to regenerate the signal. This can cause a propagation delay that affects network performance and may affect proper function. As a result, many network architectures limit the number of repeaters that can be used in a row, e.g., the Ethernet 5-4-3 rule.

Hubs and repeaters in LANs have been mostly obsoleted by modern switches.

Bridges Edit
A network bridge connects and filters traffic between two network segments at the data link layer (layer 2) of the OSI model to form a single network. This breaks the network’s collision domain but maintains a unified broadcast domain. Network segmentation breaks down a large, congested network into an aggregation of smaller, more efficient networks.

Bridges come in three basic types:

Local bridges: Directly connect LANs
Remote bridges: Can be used to create a wide area network (WAN) link between LANs. Remote bridges, where the connecting link is slower than the end networks, largely have been replaced with routers.
Wireless bridges: Can be used to join LANs or connect remote devices to LANs.
Switches Edit
A network switch is a device that forwards and filters OSI layer 2 datagrams (frames) between ports based on the destination MAC address in each frame.[16] A switch is distinct from a hub in that it only forwards the frames to the physical ports involved in the communication rather than all ports connected. It can be thought of as a multi-port bridge.[17] It learns to associate physical ports to MAC addresses by examining the source addresses of received frames. If an unknown destination is targeted, the switch broadcasts to all ports but the source. Switches normally have numerous ports, facilitating a star topology for devices, and cascading additional switches.

Multi-layer switches are capable of routing based on layer 3 addressing or additional logical levels. The term switch is often used loosely to include devices such as routers and bridges, as well as devices that may distribute traffic based on load or based on application content (e.g., a Web URL identifier).

article: Wireless network
Terrestrial microwave – Terrestrial microwave communication uses Earth-based transmitters and receivers resembling satellite dishes. Terrestrial microwaves are in the low gigahertz range, which limits all communications to line-of-sight. Relay stations are spaced approximately 48 km (30 mi) apart.
Communications satellites – Satellites communicate via microwave radio waves, which are not deflected by the Earth’s atmosphere. The satellites are stationed in space, typically in geosynchronous orbit 35,400 km (22,000 mi) above the equator. These Earth-orbiting systems are capable of receiving and relaying voice, data, and TV signals.
Cellular and PCS systems use several radio communications technologies. The systems divide the region covered into multiple geographic areas. Each area has a low-power transmitter or radio relay antenna device to relay calls from one area to the next area.
Radio and spread spectrum technologies – Wireless local area networks use a high-frequency radio technology similar to digital cellular and a low-frequency radio technology. Wireless LANs use spread spectrum technology to enable communication between multiple devices in a limited area. IEEE 802.11 defines a common flavor of open-standards wireless radio-wave technology known as Wifi.
Free-space optical communication uses visible or invisible light for communications. In most cases, line-of-sight propagation is used, which limits the physical positioning of communicating devices.
Exotic technologies Edit
There have been various attempts at transporting data over exotic media:

IP over Avian Carriers was a humorous April fool’s Request for Comments, issued as RFC 1149. It was implemented in real life in 2001.[14]
Extending the Internet to interplanetary dimensions via radio waves, the Interplanetary Internet.[15]
Both cases have a large round-trip delay time, which gives slow two-way communication, but doesn’t prevent sending large amounts of information.

Network nodes Edit
Main article: Node (networking)
Apart from any physical transmission media there may be, networks comprise additional basic system building blocks, such as network interface controllers (NICs), repeaters, hubs, bridges, switches, routers, modems, and firewalls. Any particular piece of equipment will frequently contain multiple building blocks and perform multiple functions.

Network interfaces Edit

An ATM network interface in the form of an accessory card. A lot of network interfaces are built-in.
A network interface controller (NIC) is computer hardware that provides a computer with the ability to access the transmission media, and has the ability to process low-level network information. For example, the NIC may have a connector for accepting a cable, or an aerial for wireless transmission and reception, and the associated circuitry.

The NIC responds to traffic addressed to a network address for either the NIC or the computer as a whole.

In Ethernet networks, each network interface controller has a unique Media Access Control (MAC) address—usually stored in the controller’s permanent memory. To avoid address conflicts between network devices, the Institute of Electrical and Electronics Engineers (IEEE) maintains and administers MAC address uniqueness. The size of an Ethernet MAC address is six octets. The three most significant octets are reserved to identify NIC manufacturers. These manufacturers, using only their assigned prefixes, uniquely assign the three least-significant octets of every Ethernet interface they produce.

computer network, or data network, is a digital telecommunications network thopology

Main article: Network topology
The physical layout of a network is usually less important than the topology that connects network nodes. Most diagrams that describe a physical network are therefore topological, rather than geographic. The symbols on these diagrams usually denote network links and network nodes.

Network links Edit
Further information: data transmission
The transmission media (often referred to in the literature as the physical media) used to link devices to form a computer network include electrical cable, optical fiber, and radio waves. In the OSI model, these are defined at layers 1 and 2 — the physical layer and the data link layer.

A widely adopted family of transmission media used in local area network (LAN) technology is collectively known as Ethernet. The media and protocol standards that enable communication between networked devices over Ethernet are defined by IEEE 802.3. Ethernet transmits data over both copper and fiber cables. Wireless LAN standards use radio waves, others use infrared signals as a transmission medium. Power line communication uses a building’s power cabling to transmit data.

Wired technologies Edit

Fiber optic cables are used to transmit light from one computer/network node to another
The orders of the following wired technologies are, roughly, from slowest to fastest transmission speed.

Coaxial cable is widely used for cable television systems, office buildings, and other work-sites for local area networks. The cables consist of copper or aluminum wire surrounded by an insulating layer (typically a flexible material with a high dielectric constant), which itself is surrounded by a conductive layer. The insulation helps minimize interference and distortion. Transmission speed ranges from 200 million bits per second to more than 500 million bits per second.
ITU-T G.hn technology uses existing home wiring (coaxial cable, phone lines and power lines) to create a high-speed (up to 1 Gigabit/s) local area network
Twisted pair wire is the most widely used medium for all telecommunication. Twisted-pair cabling consist of copper wires that are twisted into pairs. Ordinary telephone wires consist of two insulated copper wires twisted into pairs. Computer network cabling (wired Ethernet as defined by IEEE 802.3) consists of 4 pairs of copper cabling that can be utilized for both voice and data transmission. The use of two wires twisted together helps to reduce crosstalk and electromagnetic induction. The transmission speed ranges from 2 million bits per second to 10 billion bits per second. Twisted pair cabling comes in two forms: unshielded twisted pair (UTP) and shielded twisted-pair (STP). Each form comes in several category ratings, designed for use in various scenarios.

2007 map showing submarine optical fiber telecommunication cables around the world.
An optical fiber is a glass fiber. It carries pulses of light that represent data. Some advantages of optical fibers over metal wires are very low transmission loss and immunity from electrical interference. Optical fibers can simultaneously carry multiple wavelengths of light, which greatly increases the rate that data can be sent, and helps enable data rates of up to trillions of bits per second. Optic fibers can be used for long runs of cable carrying very high data rates, and are used for undersea cables to interconnect continents.
Price is a main factor distinguishing wired- and wireless-technology options in a business. Wireless options command a price premium that can make purchasing wired computers, printers and other devices a financial benefit. Before making the decision to purchase hard-wired technology products, a review of the restrictions and limitations of the selections is necessary. Business and employee needs may override any cost considerations.[13]

computer network, or data network, is a digital telecommunications network

A computer network may be used by security hackers to deploy computer viruses or computer worms on devices connected to the network, or to prevent these devices from accessing the network via a denial-of-service attack.

Network packet Edit

Main article: Network packet
Computer communication links that do not support packets, such as traditional point-to-point telecommunication links, simply transmit data as a bit stream. However, most information in computer networks is carried in packets. A network packet is a formatted unit of data (a list of bits or bytes, usually a few tens of bytes to a few kilobytes long) carried by a packet-switched network. Packets are sent through the network to their destination. Once the packets arrive they are reassembled into their original message.

Packets consist of two kinds of data: control information, and user data (payload). The control information provides data the network needs to deliver the user data, for example: source and destination network addresses, error detection codes, and sequencing information. Typically, control information is found in packet headers and trailers, with payload data in between.

With packets, the bandwidth of the transmission medium can be better shared among users than if the network were circuit switched. When one user is not sending packets, the link can be filled with packets from other users, and so the cost can be shared, with relatively little interference, provided the link isn’t overused. Often the route a packet needs to take through a network is not immediately available. In that case the packet is queued and waits until a link is free.

network facilitates interpersonal communications allowing users to communicate efficiently and easily via various means: email, instant messaging, online chat, telephone, video telephone calls, and video conferencing. A network allows sharing of network and computing resources. Users may access and use resources provided by devices on the network, such as printing a document on a shared network printer or use of a shared storage device. A network allows sharing of files, data, and other types of information giving authorized users the ability to access information stored on other computers on the network. Distributed computing uses computing resources across a network to accomplish tasks.

A computer network may be used by security hackers to deploy computer viruses or computer worms on devices connected to the network, or to prevent these devices from accessing the network via a denial-of-service attack.

computer network, or data network, is a digital telecommunications network

A computer network, or data network, is a digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections between nodes (data links.) These data links are established over cable media such as wires or optic cables, or wireless media such as WiFi.

Network computer devices that originate, route and terminate the data are called network nodes.[1] Nodes can include hosts such as personal computers, phones, servers as well as networking hardware. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. In most cases, application-specific communications protocols are layered (i.e. carried as payload) over other more general communications protocols. This formidable collection of information technology requires skilled network management to keep it all running reliably.

Computer networks support an enormous number of applications and services such as access to the World Wide Web, digital video, digital audio, shared use of application and storage servers, printers, and fax machines, and use of email and instant messaging applications as well as many others. Computer networks differ in the transmission medium used to carry their signals, communications protocols to organize network traffic, the network’s size, topology, traffic control mechanism and organizational intent. The best-known computer network is the Internet.

History Edit

See also: History of the Internet
The chronology of significant computer-network developments includes:

In the late 1950s, early networks of computers included the U.S. military radar system Semi-Automatic Ground Environment (SAGE).
In 1959, Anatolii Ivanovich Kitov proposed to the Central Committee of the Communist Party of the Soviet Union a detailed plan for the re-organisation of the control of the Soviet armed forces and of the Soviet economy on the basis of a network of computing centres, the OGAS.[2]
In 1960, the commercial airline reservation system semi-automatic business research environment (SABRE) went online with two connected mainframes.
In 1963, J. C. R. Licklider sent a memorandum to office colleagues discussing the concept of the “Intergalactic Computer Network”, a computer network intended to allow general communications among computer users.
In 1964, researchers at Dartmouth College developed the Dartmouth Time Sharing System for distributed users of large computer systems. The same year, at Massachusetts Institute of Technology, a research group supported by General Electric and Bell Labs used a computer to route and manage telephone connections.
Throughout the 1960s, Paul Baran, and Donald Davies independently developed the concept of packet switching to transfer information between computers over a network. Davies pioneered the implementation of the concept with the NPL network, a local area network at the National Physical Laboratory (United Kingdom) using a line speed of 768 kbit/s.[3][4][5]
In 1965, Western Electric introduced the first widely used telephone switch that implemented true computer control.
In 1966, Thomas Marill and Lawrence G. Roberts published a paper on an experimental wide area network (WAN) for computer time sharing.[6]
In 1969, the first four nodes of the ARPANET were connected using 50 kbit/s circuits between the University of California at Los Angeles, the Stanford Research Institute, the University of California at Santa Barbara, and the University of Utah.[7] Leonard Kleinrock carried out theoretical work to model the performance of packet-switched networks, which underpinned the development of the ARPANET.[8][9] His theoretical work on hierarchical routing in the late 1970s with student Farouk Kamoun remains critical to the operation of the Internet today.
In 1972, commercial services using X.25 were deployed, and later used.

Binary Search Tree – Searching, Deletion

Searching a BST is even simpler than insertion. The pseudocode is self-explanatory but we will look brie°y at the premise of the algorithm nonetheless.
We have talked previously about insertion, we go either left or right with the right subtree containing values that are ¸ x where x is the value of the node
we are inserting. When searching the rules are made a little more atomic and at any one time we have four cases to consider:

1. the root = ; in which case value is not in the BST; or
2. root.Value = value in which case value is in the BST; or
3. value < root.Value, we must inspect the left subtree of root for value; or
4. value > root.Value, we must inspect the right subtree of root for value.
1) algorithm Contains(root, value)
2) Pre: root is the root node of the tree, value is what we would like to locate
3) Post: value is either located or not
4) if root = ; 5) return false
6) end if
7) if root.Value = value
8) return true
9) else if value < root.Value
10) return Contains(root.Left, value)
11) else
12) return Contains(root.Right, value)
13) end if
14) end Contains

Deletion

Removing a node from a BST is fairly straightforward, with four cases to consider:

1. the value to remove is a leaf node; or
2. the value to remove has a right subtree, but no left subtree; or
3. the value to remove has a left subtree, but no right subtree; or
4. the value to remove has both a left and right subtree in which case we


promote the largest value in the left subtree.
There is also an implicit ¯fth case whereby the node to be removed is the only node in the tree. This case is already covered by the ¯rst, but should be
noted as a possibility nonetheless. Of course in a BST a value may occur more than once. In such case the ¯rst occurrence of that value in the BST will be removed.

The Remove algorithm given below relies on two further helper algorithms named FindP arent, and FindNode which are described in x3.4 and x3.5 re-
spectively.

How to Protect Your Data from Computer Virus Attacks

Basically, one of the main protections to keep a computer to work optimally is always protect the computer from harmful viruses. There are so many of malicious virus variants that can disrupt the smooth performance of your computer. Among them, the most popular types of computer viruses are Worm virus, Trojan, Spyware, and so forth. They all can inhibit the smoothness of your computer performance in its operation. Surely, all types of computer viruses will slow down your work in any computer task. So, you need to protect your computer from a sudden virus attack.

Virus attack is one of computer maladies that work to destroy computer data. Computer viruses are able to multiply or reproduce on your computer system. Additionally, a computer virus is also able to copy, infect and even spread other disruptions to all sectors of the program whether in the hard disk, flash disk, and other storage media. The most annoying thing when a computer is being attacked by a virus is when the computer restarts itself. But not everyone knows when a computer virus infects your data. So, you should protect your data from computer virus attracts.

Protect Your Computer from Virus Attacks

  1. First thing first to protect your computer from virus attacks is by knowing the computer virus names, learn how they infect the computer’s system, and how to prevent them.
  2. Do not leave your computer runs without antivirus. Commonly, the computer antivirus is the most powerful security of your computer.
  3. So, install a reliability antivirus. Not all antivirus are paid, but there are also some free computer antiviruses are capable of eradicating every virus that comes to the computer. As a recommendation, you can use AVG antivirus or Avira antivirus.
  4. Make sure the antivirus database on your computer is always up to date, as there would be the emerge of new computer viruses on the network. Update an antivirus could be online or offline.
  5. Scan the entire data on your computer regularly. At least you scan the data on your computer using antivirus once a week. In case there’s a virus attack on your computer, immediately quarantine the virus using your antivirus.
  6. Each time you are surfing the internet, never to open attachment file or email attachment that includes a file with extensions .exe, .scr, .vbs, or double extension files like .txt. But if you think the file is important, should scan the file first using the antivirus.
  7. Be careful when opening email attachments or post attachments from instant messages sent from unknown people, as this may contain malicious files.
  8. Never open Spam / Trash email (product sale, free video offer, free image, and free song).
  9. Always scan your new data files with your antivirus before opening them. The new files could be downloaded from the internet or from an external storage media such as flash disk, hard drive, CD/DVD, etc.
  10. Never install pirated or nulled software. Any pirated or nulled software is not from a legitimate seller/ creator. Usually, pirated software is always infected with a malicious virus used to spy your computer data.
  11. Always read the Term of Services and agreement of any free software you are going to install. If you don’t read it, you may accidentally agree with installing a bundled spyware software program that is hard to uninstall.

Finally, by applying those tips above, your computer or laptop will always out of from a malicious virus infection.

Productivity working on the computer.

If you used to work for long on computer, don’t forget about your posture. Improper posture while sitting at a desk not only poses a threat to health, but also prevents you from concentrating. This can be annoying back pain or headache, and also cause low productivity. Sitting in distorted posture or putting leg on the leg, the body gets tired, back, neck, shoulders get tense, legs soluble. The body feels the stress, so it affects your mood and ability to concentrate.

When your body gets tired, mind also refuses to work. Try to adjust the height of the chairs and table, ensure a comfortable footrest and back. The main thing is immediately stretch up! Correct posture even inspire a better mood, self-confidence.

Please note that the irregular posture may be due to lack of physical activity. Working a job in which much time you are sitting, it is very important to take time for to exercise and body strengthening exercises – so you will feel more energetic and healthier. Use your smartphone – track how many steps you take in a day or jogging track your progress.

It is important to learn how to monitor your performance and inspiration and to use the time when the work you manage to perform smoothly. Assign these moments for most important, urgent work. Understand that working hours are for a work to be done and do not try to get out of yourself more than you can.
