Computer hardwareComputer hardware, commonly shortened to hardware, includes the physical parts of a computer, such as the central processing unit (CPU), random-access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. By contrast, software is a set of written instructions that can be stored and run by hardware.Resource leakIn computer science, a resource leak is a particular type of resource consumption by a computer program where the program does not release resources it has acquired. This condition is normally the result of a bug in a program. Typical resource leaks include memory leak and handle leak, particularly file handle leaks, though memory is often considered separately from other resources.
Resource contentionIn computer science, resource contention is a conflict over access to a shared resource such as random access memory, disk storage, cache memory, internal buses or external network devices. A resource experiencing ongoing contention can be described as oversubscribed. Resolving resource contention problems is one of the basic functions of operating systems. Various low-level mechanisms can be used to aid this, including locks, semaphores, mutexes and queues.
ResourceResources are all the materials available in the environment which are technologically accessible, economically feasible and culturally sustainable and help to satisfy needs and wants. There are many types of resources, which can broadly be classified according various parameters, such as their availability as renewable or non-renewable resources or national and international resources. An item may become a resource with technology.

SoftwareSoftware (SW) consists of computer programs that instruct the execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware.Resource management (computing)In computer programming, resource management refers to techniques for managing resources (components with limited availability). Computer programs may manage their own resources by using features exposed by programming languages (Elder, Jackson & Liblit (2008) is a survey article contrasting different approaches), or may elect to manage them by a host – an operating system or virtual machine – or another program.
Cloud computingCloud computing is defined by the International Organization for Standardization (ISO) as "a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on demand". It is commonly referred to as "the cloud". CharacteristicsIn 2011, the National Institute of Standards and Technology (NIST) identified five "essential characteristics" for cloud systems.
ScarcityIn economics, scarcity refers to the basic fact of life that there exists only a finite amount of human and nonhuman resources which the best technical knowledge is capable of using to produce only limited maximum amounts of each economic good. If the conditions of scarcity did not exist and an "infinite amount of every good could be produced or human wants fully satisfied ... there would be no economic goods, i.e. goods that are relatively scarce..."
DesignA design is the concept or proposal for an object, process, or system. The word design refers to something that is or has been intentionally created by a thinking agent, and is sometimes used to refer to the inherent nature of something – its design. The verb to design expresses the process of developing a design. In some cases, the direct construction of an object without an explicit prior plan may also be considered to be a design, such as in arts and crafts.Software designSoftware design is the process of conceptualizing how a software system will work before it is implemented or modified. Software design also refers to the direct result of the design process – the concepts of how the software will work which may be formally documented or may be maintained less formally, including via oral tradition.
Processor designProcessor design is a subfield of computer engineering and electronics that deals with creating a processor, a key component of computer hardware. While historically focused on the central processing unit (CPU), modern design often involves system-on-chip (SoC) architectures, which integrate multiple processing units such as CPUs, graphics processing units (GPUs), and neural processing units (NPUs) onto a single die or set of chiplets.*As an Amazon Associate I earn from qualifying purchases.
