Computer Program Is? | Definition, Function and Examples

Hardware and software components in a computer must support each other, so that the computer can be operated according to its function.

Software also known as a computer program is a series of instructions that are designed so that the computer can perform a series of tasks desired by the brainware (users).

Understanding Computer Programs Is

As we all know that a computer is a device that is used to help a variety of human work. The computer itself consists of two main parts, namely hardware and software. The computer hardware component is a part that consists of various electronic devices ranging from screens, CPUs and keyboards and so on that can be seen and touched physically.

But of course the hardware will not work if there is no set of instructions to set it up. A series of instructions are known as software (software) or also often referred to as the program.

As mentioned earlier, a computer program is a series of instructions that are designed sequentially so that a computer can carry out a series of tasks in accordance with what is ordered by its users, so the computer actually does not have the ability to solve a problem without a computer program.

This makes a computer program can be likened to a schedule of activities whose role as a giver of instructions what activities should be done.

Well, a computer program will be able to work if it is written or arranged in one complete file, which will then be run by a computer in a central processor. The computer program was designed by a programmer using a certain algorithm and then poured in a programming language. After that, the computer program will be executed using the utility of the programming language which will then be recognized and run by the hardware.

Computer programs are usually located on the computer’s hard drive where when the program is run, the computer will immediately direct access to the storage location of the computer program and then tells the processor so that instructions from the computer program can be run as functions as desired by the user.

The Function of a Computer Program Is

A computer without a program will only be a useless machine because it cannot perform any of the tasks instructed by its users.

Therefore, a computer program is a very important thing in a computer because it basically has the main function as a tool or media to be able to control a computer so that it can be used to perform various tasks desired by its users.

However, besides functioning as a means of controlling a computer, in fact there are still several other functions of a computer program, including the following.

Link between hardware

Computer programs are designed to be able to regulate the relationship between hardware so that each hardware component in a computer can work simultaneously without obstacles and in accordance with the functions expected by its users.

Program identification tool

Although the types are the same computer programs, but there are also computer programs specifically designed to do the task as a tool to identify the program.

Such programs, for example, can be seen in the File Explorer program, which has a role as a place to access various types of programs that exist on a computer.

Linking the program with hardware

There are also computer programs that function as a liaison for a program with the hardware components in a computer. For example, such as a device manager program whose function is to manage all hardware so that it can be recognized by the Windows operating system.

Translator instructions into machine language

Examples of instruction translators into machine language that act as computer programs are compilers of programming languages. Programs that function like that, for example like Basic, C ++, Java, Visual and others.

Examples of Computer Programs Are

When viewed from its type, in general, computer programs are divided into four types, namely operating systems, applications, utilities and programming languages. For more details about the types of computer programs complete with various examples will be reviewed below:

Operating system

The operating system is basically a complex computer program which contains many other programs that function as a link between the user and the computer that he uses.

Thanks to the operating system, a computer can optimize the performance of every component in the computer. Well, examples of operating systems that include computer programs are as follows.

Microsoft Windows

This type of operating system is most often found in a computer. As the name implies, the developer who developed this operating system is Microsoft complete with an interface that uses a GUI (Graphical User Interface). From time to time the Microsoft Windows operating system has been upgraded and is now available in the Windows 10 version.

Unix

One of the advantages of this Unix operating system is a higher level of stability when compared to other types of operating systems. If you are familiar with a computer program called Linux, please note that the program is a derivative of UNIX.

Macintosh Operating System

The operating system, better known as Mac OS, was first released in 1984. Mac OS also implements an architecture similar to UNIX and also has a GUI-based interface so the stability level is also quite high.

Aplikasi
Aplikasi merupakan program yang berfungsi menjalankan tugas secara spesifik. Beberapa contoh aplikasi yang termasuk ke dalam program komputer adalah seperti berikut ini.

Utility
Utility merupakan jenis program komputer yang berfungsi sebagai maintenance, dalam hal ini mencakup tiga macam tugas, yaitu melakukan analisa, melakukan proses konfigurasi dan memberikan sistem keamanan yang optimal dalam sebuah komputer. Ada 9 jenis program komputer utility yang perlu diketahui, yaitu seperti berikut ini.

Antivirus
Sesuai namanya, maka sudah bisa disimpulkan bahwa program komputer ini adalah untuk menjaga keamanan komputer agar tidak mudah terserang virus berbahaya.

Tentunya setiap komputer harus memiliki setidaknya 1 jenis program komputer antivirus sebab bila tidak maka sistem operasi dalam sebuah komputer akan memiliki resiko tinggi mengalami kerusakan data yang disebabkan oleh virus.

Selain kerusakan data, ada berbagai resiko yang bisa dicegah dengan terpasangnya antivirus dalam sebuah komputer misalnya seperti mengalami pencurian data yang sensitif atau bahkan komputer tersebut akan mudah diretas oleh hacker.

Contoh program komputer yang termasuk antivirus adalah AVG Antivirus, Microsoft Security Essentials, Avira, McAfee, Kaspersky, BitDefender, dan lain sebagainya. Selain itu, ada pula program komputer antivirus yang merupakan buatan lokal (buatan Indonesia) contohnya seperti Smadav dan PCMAV.

Perlu diketahui pula, bahwa sebagian besar program komputer antivirus merupakan program berbayar untuk bisa menggunakannya. Namun, ada pula program antivirus yang menyediakan dua versi, yaitu versi gratis dengan sejumlah batasan fitur dan ada pula yang menyediakan versi trial atau uji coba yang membuat Anda bisa menggunakan program antivirus tersebut secara full dan gratis namun untuk sementara saja.

Setelah batas waktu yang ditentukan berakhir maka Anda harus mulai membayar agar program antivirus tersebut tetap bisa diaktifkan dan berfungsi sebagaimana mestinya. Selain itu, jangan lupa untuk melakukan update program antivirus secara berkala.

Archivers dan Data Compression
Program komputer ini bertugas untuk membuat beberapa file menjadi satu kesatuan dalam bentuk arsip sekaligus memperkecil ukuran dari file tersebut.

Program komputer ini sangat berguna jika Anda ingin mengirim file dalam jumlah yang cukup banyak melalui email, dengan adanya program komputer ini Anda tidak perlu berkali-kali memasukkan file, hanya sekali saja, dan file-file tersebut akan langsung terkirim dengan cara yang lebih praktis, ukurannya pun lebih kecil.

Contoh dari program komputer ini diantaranya seperti WinRAR, WinZip, FilZip, 7-Zip, PowerISO yang sudah dilengkapi pula dengan virtual disk drive dan lain sebagainya. Kebanyakan pengguna komputer biasanya menggunakan WinRAR, namun program ini merupakan salah satu program komputer berbayar sehingga memiliki versi trial yang dibatasi oleh waktu biasanya hanya 30 hari saja dan jika Anda ingin terus menggunakannya maka Anda harus membeli lisensinya.

Backup software
This computer program is a type of program that functions to create archives originating from hard disk drive partitions with the aim of archiving as backups. Examples of these programs include Norton Ghost, Nova Backup and Acronis True Image.

Disk Checkers
This computer program is a type of program that is used to facilitate computer users to be able to check the status of the hard disk drive. Examples of these programs include CrystalDiskInfo and HDSentinel.

The purpose of checking the hard disk drive is to find out the status, be it health, temperature and various other aspects of a computer hard disk. Things like that need to be done, so you can prevent fatal damage to the hard disk drive, for example such as the occurrence of hard disk bad sectors which are certainly dangerous to various data in the computer.

Actually, each operating system has its own disk checkers program but additional computer programs such as CrystalDiskInfo and HDSentinel will function better because various information about the condition of the hard disk is presented in more detail, even there is also information relating to the remaining age of the hard disk drive before experiencing damage.

Disk Cleaners
Disk Cleaners computer program functions to clean various files stored on hard disk drives that are considered as junk files (junk files). Things like that will make you able to further optimize the free space on a hard disk drive. Examples of these computer programs such as CCleaner.

Disk Defragmenters
This computer program is a program that works to defragment a partition from a hard disk drive. This makes the free space on a hard disk drive can be further optimized and the process of reading the data will be done faster.

Disk Partition Editors
This computer program serves to adjust the partition size. Examples of disk partition editors include programs such as Partition Wizard and Partition Magic. Keep in mind that the size of partitions on a hard disk drive should be adjusted according to needs.

For example, on partitions that store large and large data, for example, such as video files, the size of the partition should be larger, while data that is smaller, for example, such as data in the form of documents, the partitions are made smaller.

Registry Cleaner
Did you know, especially for those of you who use the Windows operating system that the more often the Windows operating system is used, the state of the registry will automatically become increasingly inefficient?

Therefore, the registry should be cleaned regularly, fortunately computer programs like CCleaner have additional features that can be used to clean the registry in the Windows operating system.

Startup Manager
The first time a computer is turned on from a state that was previously turned off, then there will immediately be a computer program that comes on along with the operating system. Things like that will extend the boot time process of a computer.

Therefore computer programs and services that are automatically activated when a computer is on must go through a control process by not activating computer programs and services that are not really needed at the startup process of a computer.

It’s just that you need to be careful when disabling computer programs when doing startup because there are some computer programs that are really needed during the startup process.

Programming language
Another type of computer program that is no less important is a programming language that contains various instructions so that a computer can perform certain functions. Examples of programming languages include:

– Low Level Language, an example of this programming language such as Assembly.
– Middle Level Language, an example of this programming language such as Language C.
– High Level Language, examples of these programming languages such as Basic and Pascal.
– Object Oriented Language, examples of these programming languages include Visual C, Delphi, Visual dBase, and Visual FoxPro.

That is a complete review of computer programs including understanding, functions and examples. The above review is expected to make you easier to understand computer programs in more detail.
