Linked lists. A linked list is a collection of structures ordered not by their physical placement in memory but by logical links that are stored as part of the data in the structure itself. It is not necessary that it should be stored in the adjacent memory locations. Every structure has a data field and an address field.
Structural inequality occurs when the fabric of organizations, institutions, governments or social networks contains an embedded bias which provides advantages for some members and marginalizes or produces disadvantages for other members. This can involve property rights, status, or unequal access to health care, housing, education and other ...
Bus network. A bus network is a network topology in which nodes are directly connected to a common half-duplex link called a bus. [1] [2] A host on a bus network is called a station. In a bus network, every station will receive all network traffic, and the traffic generated by each station has equal transmission priority. [3]
Network topology is the topological [4] structure of a network and may be depicted physically or logically. It is an application of graph theory [3] wherein communicating devices are modeled as nodes and the connections between the devices are modeled as links or lines between the nodes. Physical topology is the placement of the various ...
In 2017, education reforms in Uzbekistan changed from 12-year program to 11 years after a previous reform disappointed and troubled parents and children. Eleven years of primary and secondary education are obligatory, starting at age seven. The rate of attendance in those grades is high, although the figure is significantly lower in rural areas ...
Piggybacking (data transmission) In two-way communication, whenever a frame is received, the receiver waits and does not send the control frame (acknowledgment or ACK) back to the sender immediately. The receiver waits until its network layer passes in the next data packet. The delayed acknowledgment is then attached to this outgoing data frame ...
Antennas. Wi-Fi ( / ˈwaɪfaɪ /) [1] [a] is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks, used globally in ...
Error-correcting codes are used in lower-layer communication such as cellular network, high-speed fiber-optic communication and Wi-Fi, as well as for reliable storage in media such as flash memory, hard disk and RAM. Error-correcting codes are usually distinguished between convolutional codes and block codes:
