Word processing programs

Today, people use computers equipped with word-processing programs. It is one of the most widely used applications on computers. A word-processing program is software that can be used to type and edit reports letter and tablets.

Font, color and size of the text also can be changed in word processing.

Word processing program such Microsoft Word enables the user to produce professional looking, well styled documents for many different purposes. The programs allow a user to type letters, memos, and reports. Most programs also have templates, which are pre-made layouts of the most common letters, memos, and reports as well as fax cover sheet.

Acquiring world processing skills will make sure the user more efficient on his everyday tasks because there is such a a variety of documents available the user need to be able to choose the best one for the job.

Coding in computer programming

The process of coding a computer program depends on the programming language used. Programmers typically use a text editor, program editor or VDE to code computer programs.

Coding starts with a programmer working on a computer. Before proceeding to write a code, the programmer must ensure that the appropriate is installed on the computer.

A programming language like C++is called higher level language. The program written using it is called source code.

The compiler is a program that converts this source code into machine code.  The translation from source code to machine code is called code assembly.

In Windows operating system, a machine code is in the form of an ‘exe’ file. Such file can be run on the computer directly.

Many programmers use computer software engineering tools to automate a great deal of the coding process.

The tools can generate entire sections of code automatically rather than one line at a time.

Database program

Database management is very crucial and tedious work for every organization as databases contains all important information’s of an organization.

A database acts like a big bucket where the user can put in information. The two most important parts of any databases is storing information and take it back out again.

A modern-day database is a structure collection of data in a computer. The term structured implies that each record in the database sis stored in a certain format.

An application programs is needed to retrieve or manipulate data in this file. The data retrieval capability is provided by a query language and the data manipulation capability is provided with a transaction language.

Database programs differ from other types of computer programs in the sense that they are dominated by data retrieval and manipulation tasks rather than complex computation.

A database management system is a specific type of software than can organize data in a flexible manner. It has the ability to add, modify or delete data from the database, ask question or queries about the data stored in the database, and also summarize selected contents.

General purpose application programs

General purpose application programs are programs that serve varies purposes, such as developing decision-making tools, or creating documents. It is also known as ‘generic’ software.

For example, spreadsheets, word processing programs, and graphics programs are popular with microcomputer users for home, education, business, scientific, and many other purposes.

Many of these general purpose software programs now come with a built programming language and so this extends the scope of the software’s usage and so fits even closer to definition ‘suitable for a variety of tasks.

Because they significantly increase the productivity of end users, they are sometimes known as productivity software packages.

Their examples include Web browsers, electronic mail, and groupware, which help support communication and collaboration among workgroups and teams.

General purpose applications are available as packaged software; that is they come ready to install from an external storage medium such as CD or a file downloaded from a vendor’s web site.

What is Computer Hacking?

Hacking, in computerese, is the obsessive use of computers, or the unauthorized access and use of networked computer system. Illegal hackers (also called crackers) frequently assault the internet and other networks to steal or damage data and programs.

One of the issues in hacking is what to do about a hacker who commits only electronic breaking and entering: that is, gets access to a computer systems, reads some files, but neither steals nor damages anything.

This situation is common in computer crime cases that are prosecuted. In several states, courts have found that the typical computer crime statute language prohibiting malicious access to a computer system did apply to anyone gaining unauthorized access to another’s computer networks.

Hackers can monitor E-mail, Web server access, or file transfer to extract passwords or steal network files, or to plant data that will cause a system to welcome intruders. A hacker may also use remote services that allow one computer on a network to execute programs on another computer to gain privileged access within network.

Telnet, an internet tool for interactive use of remote computers, can help hackers discover information to plan other attacks. Hackers have used telnet to access computer E-mail port, for example, to monitor E-mail messages for password and other information about privileged user accounts and networks resources.

These are just some of the typical types of computer crimes that hackers commit on the internet on a regular basis. That is why internet security measures like encryption and fire walls, are so vital to the success of electronic commerce and other E-business applications.
