Computers have become an essential part of every household and business throughout the world. As the demand for computers continues to increase, the need for IT specialists and computer technicians has also become aggressive. Due to this, certification, degrees, and short courses in IT and computer technology have been on the rise. The following are the areas of IT and computing that are now in constant demand:

• Service, repair and maintenance, and upgrades of hardware and software
• Networking setup and support
• Administration of security and virus protection
• IT Consulting
• Programming services
• Desktop Publishing
• Software Engineering
• Video game programming and design
• Web design

There are businesses in the country that provide professional help to home users and businesses alike. Also, freelance computer technicians, IT specialists, and computer programmers can be hired for any long term or project based services. Some forms of IT or technical support and even programming are also done offshore or through outsourcing.

The most common issues that need attention are coming from home users. Many of the cases dealt with include computers that are infected with viruses, malware or spyware. The type of troubleshooting applied on these cases can both be done through phone support or in person. Customers may be required to bring their computers or laptops to various business centres for repair, and the turn around time depends on some factors such as warranty coverage or the availability of the parts that need replacement. Otherwise, it is also an option to have the technician dispatched for home service. Technicians are also hired to perform system maintenance that may require them to replace parts or upgrade some computer hardware to improve or repair the computers performance. That being said, there are dealers who also sell parts of computers and laptops.

Programmers or software engineers on the other hand are in demand for businesses as they can write and design various software solutions. Computer programming covers a diverse area; therefore programmers are classified in two groups. The systems programmers make some changes in the instructions that dictate how the systems network, workstations, and CPU communicate with other peripheral equipments. The application programmers on the other hand are assigned to encode or revise an existing software to customize its generic application and make it a more suitable and efficient tool within an organization.

A software engineer can either be equipped in a specific programming language, or can be a generalist in various codes that can be utilized in writing different kinds of software. Programmers use different programming languages depending on the clients requirements. Computer programs have many applications such as a program to track inventory, for accounting, and database or customer relationship management. Some programmers are hired to perform debugging which is the process of checking or testing codes written in the preferred language. This task is considered to be an essential part in the process of software development. At this point, the software may or may not have been written by the same programmer who will perform debugging.
