To be used efficiently, all computer software needs certain hardware components or other software resources to be present on a computer. [1] These prerequisites are known as (computer) system requirements and are often used as a guideline as opposed to an absolute rule. Most software defines two sets of system requirements: minimum and recommended.
In modern computers, location-addressable storage usually limits to primary storage, accessed internally by computer programs, since location-addressability is very efficient, but burdensome for humans. File addressable Information is divided into files of variable length, and a particular file is selected with human-readable directory and file ...
"Procedures are to people what software is to hardware" is a common analogy that is used to illustrate the role of procedures in a system. People: Every system needs people if it is to be useful. Often the most overlooked element of the system is the people, probably the component that most influences the success or failure of information systems.
The primary components of an IT Infrastructure are the physical systems such as hardware, storage, any kind of routers/switches and the building itself but also networks and software . [9] In addition to these components, there is the need for “IT Infrastructure Security”.

The total data storage space of a PC HDD on which MBR partitioning is implemented can contain at most four primary partitions, or alternatively three primary partitions and an extended partition. The Partition Table , located in the master boot record, contains 16-byte entries, each of which describes a partition.
An operating system (OS) is system software that manages computer hardware and software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, peripherals, and other ...
A local file system manages storage space to provide a level of reliability and efficiency. Generally, it allocates storage device space in a granular manner, usually multiple physical units (i.e. bytes). For example, in Apple DOS of the early 1980s, 256-byte sectors on 140 kilobyte floppy disk used a track/sector map. [citation needed]
