A system of interconnected computers that share a central storage system and various peripheral devices such as a printers, scanners, or routers. Each computer connected to the system can operate independently, but has the ability to communicate with other external devices and computers.
What Is Computer Software? (© Computer Learning Tips)
Computer software is a general term that describes computer programs. Related terms such as software
programs, applications, scripts, and instruction sets all fall under the category of computer software.
Therefore, installing new programs or applications on your computer is synonymous with installing new
software on your computer.
Software can be difficult to describe because it is “virtual,” or not physical like computer hardware.
Instead, software consists of lines of code written by computer programmers that have been compiled into a
computer program. Software programs are stored as binary data that is copied to a computer’s hard drive,
when it is installed. Since software is virtual and does not take up any physical space, it is much easier
(and often cheaper) to upgrade than computer hardware.
While at its most basic level, software consists of binary data, CD-ROMs, DVDs, and other types of media
that are used to distribute software can also be called software. Therefore, when you buy a software
program, it often comes on a disc, which is a physical means of storing the software.
Shortly:
Software:
Computer required a number of instructions to do any job. The set of these instructions forms programs.
Numbers of programs are combined for some purposes are called software.
They are designed by manufactures and programmers.
Types of Software
1. System Software
2. Application Software
System Software:
System software refers to the files and programs that make up your computer’s operating system. System files include libraries of functions, system services, drivers for printers and other hardware, system
preferences, and other configuration files. The programs that are part of the system software include
assemblers, compilers, file management tools, system utilites, and debuggers.
The system software is installed on your computer when you install your operating system. You can update the software by running programs such as “Windows Update” for Windows or “Software Update” for Mac OS X. Unlike application programs, however, system software is not meant to be run by the end user. For example, while you might use your Web browser every day, you probably don’t have much use for an assembler program (unless, of course, you are a computer programmer).
Since system software runs at the most basic level of your computer, it is called “low-level” software. It
generates the user interface and allows the operating system to interact with the hardware. Fortunately, you
don’t have to worry about what the system software is doing since it just runs in the background. It’s nice
to think you are working at a “high-level” anyway.
Application Software:
Application software is the name given to the programs that perform specific tasks for users. For example,
games, instant messengers, word processors, and antivirus programs are all applications.
programs, applications, scripts, and instruction sets all fall under the category of computer software.

What Is Computer Hardware? (© Computer Learning Tips)
Computer Hardware refers to the physical parts of a computer and related devices. Internal hardware devices include motherboards, hard drives, and RAM. External hardware devices include monitors, keyboards, mice, printers, and scanners.
The internal hardware parts of a computer are often referred to as components, while external hardware devices are usually called peripherals. Together, they all fall under the category of computer hardware.
Software, on the other hand, consists of the programs and applications that run on computers. Because
software runs on computer hardware, software programs often have system requirements that list the minimum hardware required for the software to run.

Some Typing Rules (© Computer Learning Tips)
Learning the keyboard is the first step to learning computers. Learning involves practice. It really is as simple as that. There are two kinds of typing.
The first is called Touch Typing. The Touch Typist uses the Home Keys asdf for the left hand and jkl; for the right) and all the fingers on both hands as well as the thumbs for the Space Bar while typing. There are many commercial and public domain programs that are designed to teach this method.
The other method is some times called "Hunt and Peck" or depending on finger strength ‘Search and Destroy’. This involves using one or more fingers on one or two hands to type. It is a perfectly acceptable way of using a computer and many people get along fine with this technique.
Learn Three Basic Computer Operations (© Computer Learning Tips)
Input: Information and programs are entered into the computer through Input devices such as the keyboard, disks, or through other computers via network connections or modems connected to the Internet. The input device also retrieves information off disks.
Output: Output Devices displays information on the screen (monitor) or the printer and sends information to other computers. They also display messages about what errors may have occurred and brings up message or dialog box asking for more information to be input. The output device also saves information on the disk for future use.
Processing: The CPU or central processing unit is sometimes called the Control Unit and directs the operation of the input and output devices. The Co processor or the Arithmetic-Logic Unit does arithmetic and comparisons. The memory or RAM temporarily stores information (files and programs) while you are using or working on them. The BIOS or basic input/output system controls the dialogue between the various devices.
