The computer itself the hardware cannot do anything. The ingredient that enables a computer to perform a specific task is software, which consists of electronic instructions. These instructions tell the machine’s physical components what to do; without them, a computer could not do anything at all.
System Software:
The program directly related to the hardware of the computer and which perform the fundamental task are termed as system software.
Several programs may be included in system software but the following are essential for any computer.
Language Translators
A Particular translator is required to execute any high-level language program.
Each language has a different language translator, while the function of each translator is to convert the high-level program into machine code.
These translators are categorized into the following groups.
Interpreter:
These translators translate only one instruction at a time and execute it. After execution, the translation is erased from memory and the next instruction is loaded for translation. Therefore translation is required again if the program is executed again.
It is a limitation of interpreters that it forgets translation after the execution of the instruction.
A GWBASIC interpreter is required to run GWBASIC programs.
Each programming language has its separate interpreter if it is designed.
Compiler
These translators are used to translate the entire program at once and store their translated program on disk.
The original program is called “Source Program” while its translated program is called “Object Program”.
These translators can not execute an object program.
The object program has to go through some other stages to be able to execute.
Assembler
The assemblers are language translators for low-level symbolic language programs.
Assemblers can translate a source program into an object program.
An assembler translates one source instruction into exactly one machine code.
The linking process is required on the object program to be able to execute it.
Each low-level symbolic language has its assembler.
Application software: helps users solve particular problems
In most cases, application software resides on the computer’s hard disk
Application software can also be stored on CDs, DVDs, and flash or key chain storage devices

Editor's Notes
Quantitative data deals with numbers and things you can measure objectively: dimensions such as height, width, and length. Temperature and humidity. Prices. Area and volume.
Qualitative data deals with characteristics and descriptors that can't be easily measured, but can be observed subjectively—such as smells, tastes, textures, attractiveness, and color.
Discrete data is a count that can't be made more precise. Typically it involves integers. For instance, the number of children (or adults, or pets) in your family is discrete data, because you are counting whole, indivisible entities: you can't have 2.5 kids, or 1.3 pets.
Continuous data, on the other hand, could be divided and reduced to finer and finer levels. For example, you can measure the height of your kids at progressively more precise scales—meters, centimeters, millimeters, and beyond—so height is continuous data.
Binary data place things in one of two mutually exclusive categories: right/wrong, true/false, or accept/reject.
When collecting unordered or nominal data, we assign individual items to named categories that do not have an implicit or natural value or rank. If I went through a box of Jujubes and recorded the color of each in my worksheet, that would be nominal data.
nominal data include country, gender, race, hair color etc. of a group of people
We also can have ordered or ordinal data, in which items are assigned to categories that do have some kind of implicit or natural order, such as "Short, Medium, or Tall." Another example is a survey question that asks us to rate an item on a 1 to 10 scale, with 10 being the best. This implies that 10 is better than 9, which is better than 8, and so on. ordinal data include having a position in class as “First” or “Second”.
The difference between interval and ratio scales comes from their ability to dip below zero. Interval scales hold no true zero and can represent values below zero. For example, you can measure temperature below 0 degrees Celsius, such as -10 degrees.
Ratio variables, on the other hand, never fall below zero. Height and weight measure from 0 and above, but never fall below it.
System utilities
Anti-virus utilities scan for computer viruses and block or remove them.
Clipboard managers expand the clipboard functionality of an operating system.
Computer access control software grants or denies requests for access to system resources.
Debuggers typically permit the examination and modification of data and program instructions in memory and on disk.
Diagnostic programs determine and report the operational status of computer hardware and software. Memory testers are one example.
Network utilities analyze the computer's network connectivity, configure network settings, check data transfer or log events.
Package managers are used to configure, install or keep up to date other software on a computer.
Registry cleaners clean and optimize the Windows Registry by removing old registry keys that are no longer in use.
System monitors monitor resources and performance in a computer system.
System profilers provide detailed information about installed software and hardware.
Storage device management utilities
Backup software makes copies of all information stored on a disk and restores either the entire disk (aka Disk cloning) in an event of disk failure or selected files that are accidentally deleted or corrupted. Undeletion utilities are sometimes more convenient.
Disk checkers scan an operating hard drive and check for logical (filesystem) or physical errors.
Disk compression utilities transparently compress/uncompress the contents of a disk, increasing the capacity of the disk.
Disk defragmenters detect computer files whose contents are scattered across several locations on the hard disk and collect the fragments into one contiguous area.
Disk formatters prepare a data storage device such as a hard disk, solid-state drive, floppy disk or USB flash drive for initial use. These are often used to permanently erase an entire device.
Disk partition editors divide an individual drive into multiple logical drives, each with its own file system which can be mounted by the operating system and treated as an individual drive.
Disk space analyzers provide a visualization of disk space usage by getting the size for each folder (including sub folders) and files in folder or drive. showing the distribution of the used space.
Tape initializers write a label to a magnetic tape or other magnetic medium. Initializers for DECtape formatted the tape into blocks.
File management utilities
Archivers output a stream or a single file when provided with a directory or a set of files. Archive suites may include compression and encryption capabilities. Some archive utilities have a separate un-archive utility for the reverse operation. One nearly universal type of archive file format is the zip file.
Cryptographic utilities encrypt and decrypt streams and files.
Data compression utilities output a shorter stream or a smaller file when provided with a stream or file.
Data conversion utilities transform data from a source file to some other format, such as from a text file to a PDF document.
Data recovery utilities are used to rescue good data from corrupted files.
Data synchronization utilities establish consistency among data from a source to a target data storage and vice versa. There are several branches of this type of utility:
File synchronization utilities maintain consistency between two sources. They may be used to create redundancy or backup copies but are also used to help users carry their digital music, photos and video in their mobile devices.
Revision control utilities can recreate a coherent structure where multiple users simultaneously modify the same file.
Disk cleaners find files that are unnecessary to computer operation, or take up considerable amounts of space.
File comparison utilities provide a standalone capability to detect differences between files.
File managers provide a convenient method of performing routine data management, email recovery and management tasks, such as deleting, renaming, cataloging, uncataloging, moving, copying, merging, setting write protection status, setting file access permissions, generating and modifying folders and data sets.
Miscellaneous utilities
Data generators (e.g. IEBDG) create a file of test data according to specified patterns.
Hex editors directly modify the text or data of a file without regard to file format. These files can be data or programs.
HTML checkers validate HTML code and check links.
Installation or setup utilities are used to initialize or configure programs, usually applications programs, for use in a specific computer environment. There are also Uninstallers.
Patching utilities perform alterations of files, especially object programs when program source is unavailable.
Screensavers prevent phosphor burn-in on CRT and plasma computer monitors.
Sort/Merge programs arrange records (lines) of a file into a specified sequence.
Standalone macro recorders permit use of keyboard macros in programs that do not natively support such a feature.
