General Hardware

There are lots of different types of hardware that are used in information technology, but the most important parts of IT is the computer itself.

The computer is possibly the most important technological advance in the past century. But, a computer is also the tool that is used to monitor any IT service around the world and is one of the most important elements that IT professionals use on a daily basis. 

Operating Systems

The operating system is one of the most important elements to a computer because every computer needs an operating system to work. There are a few different operating systems that most people will be familiar with, like a Microsoft operating system, a Mac OS X operating system, or a Linux operating system. With the invention of mobile phones, there are also operating systems for phones as well as tablets. For a larger system, like the ones used in larger corporations and companies, it functions as a security system. It controls everything in the IT system and makes sure that users don't interfere with each other as well as protects the system from any unauthorized threats.  

Applications

Next up are the applications on the system. Applications are an extremely important part of any computer and can be divided into two different types of application software. The first is systems software. Systems software is the lower level of the software and often involves controlling the operating system, the utilities, and other standard tools. The applications software is the standard elements of a computer, including games, word processors, graphic processors, and spreadsheets. 

Databases

A database is another element that is used by IT professionals everyday. For any large company or corporation, a database stores a lot of the important information. Each database needs a DBMS, which IT professionals work with on a daily basis. Any information in a database can be accessed from a small computer or from a huge mainframe system.  

Storage

Storage is something that is more familiar to those who are not IT professionals because it has become more common to use storage (especially cloud storage), but there are many different types of storage that IT professionals use. The main types of mass storage include hard disk drives, magnetic tape drives, magneto-optical disc drives, optical disc drives, and solid state drives. Storage is used for many different things, but most often it is used for backing up files. 

Servers

Lastly, the servers are one of the most important parts to any IT professionals' work. There are a few different types of servers and all manage network resources. A file server is simply dedicated to storing files on the server and any user has access to the files on the network. A print server is in control of the many different printers in a company. A network server controls the network traffic of the entire system of computers. Lastly, a database server is a system that controls database queries. All of these different servers are considered to be "dedicated," which means they work solely on the tasks they are assigned. 

Overall, there are a lot of IT services in Greenville, SC, and all use the above programs and hardware to make their IT services effective and secure.
