Hardware
securely deleting files from a hard disk drive to the point beyond data recovery. Utilizes zeroes and ones to overwrite data onto all sectors of the device, effectively deleting data permanently.
Disk Wiping / Secure Delete
method by which the size of a file is decreased in order to save storage space.
This cycle involves the design and implementation of the complete system including such things as software requirements, hardware requirements and any organizational restructuring that might be needed.
System Development Life Cycle
a collection of statements that are grouped together to perform an operation. This is a block of code which only runs when it is called.

54D
copyrighted software provided at no cost; retains all rights to software programmers; programmers typically cannot incorporate this software into the application they intend to sell.
Freeware
This feasibility report determines if there is existing technology sufficient to implement the proposed system?
Technical Feasibility
refers to a type of computer programming (software design) in which programmers define the data type of a data structure, and also the types of operations (functions) that can be applied to the data structure.
OOP
Name given to the latest version of Android OS launched in September 2019
Android 10
the process of maintaining the consistency and uniformity of data instances across all consuming applications and storing devices. It ensures that the same copy or version of data is used in all devices - from source to destination.
Data Synchronization
a type of system software that performs the management of internal and external disks on a computer; includes compression defragmenting, scrubbing, etc.
Disk Utility Software
This is a part of the SDLC - Bugs (errors), or worse, flaws in the initial design have to be fixed while the program/system is in use. However, fixing a bug is a dangerous process as other bugs are likely to be introduced. The maintenance process has been said to be "two steps forward, one step back ".
Maintenance
It is called when an instance of the class is created
Constructor
Google's Self-Driving Car company
Waymo
its powerful features such as storage space and processing power. Usually used by large organizations to handle high volume input and output. Mainframes have the ability to run multiple operating systems at a time having multiple users be able to use it at a time.
Mainframe
a promise or assurance by one party that specific conditions are true or will happen; the other party is permitted to rely on that promise and seek some type of remedy if it is not true or followed
Warranty
refers to an error condition where data is lost or destroyed due to system failure.
Data Loss
4 concepts of OOP
Abstraction, Inheritance, Polymorphism, Encapsulation
The new CEO of Alphabet
Sundar Pichay
the register in a computer's processor, or central processing unit, CPU, that stores the data being transferred to and from the immediate access storage.
Memory Data Register MDR
system software that reorganizes a disk so that files are stored in contiguous (side-by-side) sectors, thus speeding up disk access and computer performance
Defragmentation
This is a risky implementation since the company starts the new system and immediately shuts down the old work process. If the new system does not work properly then there is a huge risk of a system shutdown.
Direct Changeover
a concept by which we can use a single action in different ways.
Polymorphism
