Networks
A type of device that provides interconnection with other networks that use the same protocol.
What is a Bridge?
This model breaks down project activities into linear sequential phases, where each phase depends on the deliverables of the previous one
How does the waterfall model work?
Each node of a list is made up of two items - the data and a reference to the next node. The last node has a reference to null
What is a linked list?
A data structure in the operating system kernel containing the information needed to manage the scheduling of a particular process.
What is the Process Control Block?
This is a type of networking where all nodes cooperate to distribute data amongst each othe
What is Mesh Topology?
A device that converts analogue to digital signals over phone lines using telephone or cable lines
What is a modem?
This model divides the development cycle into smaller, incremental models in which users are able to get access to the product at the end of each cycle
What is the Evolutionary Model?
A collection of elements which adds an element to the collection and removes the most recently added element
What is stack?
The act of temporarily interrupting a task being carried out by a computer system, without requiring its cooperation, and with the intention of resuming the task at a later time
What is preemptive scheduling?
A type of network topology that uses two or more differing network topologies
What is a hybrid topology?
This networking device inspects a data packet's destination address (IP address), calculates the best way for it to reach its destination and forwards it
What is a Router?
This type of testing is performed to identify all possible issues/bugs before releasing the product to everyday users or the public
What is Alpha Testing?
A container of objects in a linear collection that are inserted and removed according to the first-in first-out (FIFO) principle
What is a Queue?
A process or thread enters a waiting state because a requested system resource is held by another waiting process, which in turn is waiting for another resource held by another waiting process.
What is Deadlock?
A network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node
What is the RING Topology?
Multiple data cables are plugged into this device to enable communication between different networked devices. Operate at data link layer
What is a switch?
The purpose of this testing is to validate that each unit of the software performs as it was designed
What is the purpose of Unit Testing?
An efficient search for finding an item from a sorted list. It works by repeatedly dividing in half the portion of the list that could contain the item, until you've narrowed down the possible locations to just one.
What is a binary search?
A computer's virtual memory resources are overused, leading to a constant state of paging and page faults, causing the performance of the computer to degrade or collapse.
What is Thrashing?
In this topology, if a node fails, the entire network does NOT fail
What is an advantage of the star topology?
The most basic networking device that connects multiple computers or other network devices together and broadcasts data to the entire network.
What is a hub?
Risks pertaining to a software product or application, which may arise due to its inefficiency to function desirably to meet the expectation of the users.
What are product risks?
Also referred to as a Sinking Sort
What is another name for Bubble Sort?
Time slices are assigned to each process in equal portions and in circular order, handling all processes without priority
What is Round Robin work scheduling?
A networking hardware device that allows other Wi-Fi devices to connect to a wired network
What is a Wireless Access Point?
