Different Types of Computer Systems

Computers have become a part of everyday life. Be it in schools, offices, banks, and other such public places, we use computers on a regular basis now. Even in the schools also, students are taught about computers, it’s type, software, hardware, and different computer programming languages also. It has made our life easier, as we can do many things with the help of a computer. From watching movies to playing games, from networking with friends to sharing pictures and videos with friends, from online shopping to online bill payments, and even the real-time processing, business transactions, banking, reservations, all of these are done with the help of computer systems only.

With time the computer systems have also evolved. As earlier, we used supercomputers. And these days we are using personal computers which includes desktop, laptop, and palmtop also. The size of the computer systems in becoming small but the technology is increasing. No one would have thought before that we will have portable computer systems also in the form of laptops and palmtops. Many people are still not aware of the different forms of computer systems. So, here we will share the info about the different types of computer systems.

Super Computers– Supercomputers are said to be one of the most powerful computers because of their fast speed. They need vast space and have really good storage capacity. However, these computers are very expensive in comparison with the other computers. As we just mentioned above that they require vast space, so you should also know that many of the supercomputers need a complete building for their installation. They are usually kept in a cool or air-conditioned room. When we compare the speed of supercomputers with a desktop or other computers, the supercomputers speed is much faster and quicker which can process any information in nanoseconds or picoseconds. These supercomputers are not used for general purpose or day to day use like chatting, or shopping, or playing games. It is used in the complex processes like determining the climate, examining space, monitoring the earthquakes, and many other such processes. The first Supercomputer was CDC 6600, which was designed in the year 1964, by Seymour Cray. Some other supercomputers are Tianhe – 2, IBM Deep Blue and PARAM 10000.

Mainframe Computer – These computers are known for processing millions of instructions and guidelines per second. However, they are not as quick as the supercomputers but are still known as one of the quick computers. They are also helpful in storing huge amount of data and information. They are very huge and are very expensive also. The mainframe computers are mostly used in the organizations which need to process huge data and have to store huge information like in the railway reservations, educational institutions, and other such places where there is the need of storing bulk information. Some of the examples of mainframe computers are IBM Z890 and Hitachi’s Z800. These are utilized in a lot of tech businesses and startup app companies. Many dating and hook up apps utilize mainframe computers to collect and analyze the data from their members.

Minicomputers – These computers are smaller in size in comparison to the supercomputers and mainframe computers. They do have good speed, but it is not as quick and good as the speed of supercomputers and mainframe computers. But these computers are less expensive than the above two types of computers. Mostly, the minicomputers are used for monitoring the manufacturing process or the production in any private organization. The operating system of minicomputers is quite difficult to operate. The minicomputers which are very powerful and effective are known as the Super Minis. The examples of minicomputers are Texas Instrument TI-990 and VAX.

Microcomputers – Microcomputers are also known as Personal Computers. In comparison with the supercomputers, mainframe computers, and minicomputers, the Microcomputers are the smallest computer systems. They also are cheapest in comparison to the above-mentioned computer systems. These are the computers which are used these days for different kinds of work and activities. These computers are used by most of the people in day to day life. They do have both primary storage and secondary storage. The input and output units are also present in the microcomputers. You can either place them on the desk or can even carry them with yourself as they are portable also. The microcomputer’s examples are PC or Desktop, Laptop, Palmtop, and Tablet.

What Does a Computer Systems Analyst Do?

A computer system analyst is one of the most important persons in a modern organization and is currently seen as an indispensable professional to understand the computer system and solving its problem by using information technology. In today’s world it goes without saying that the backbone of any large organization is its computer system. It is only through a well established computer system that an organization effectively analyzes levels of efficiency and implementation of procedures in order to streamline the entire operations of the company.

In very small organizations the case may not be so as the business manager can look after day to day operation of the business and manage and judge the staff working there manually or with little computerization. It is only when these businesses scale to higher levels and faces new challenges that it becomes imperative to install a good computer system so as to save time and cut costs. In this context, an organization hires a computer system analyst to do a thorough analysis of the business with the help of its business manager or business analyst to design the whole of its information system so that the business operates without any problems as effectively as possible.

Does Your Organization Need an IT system?

The first thing that a professional computer system analyst would dwell would be whether the organization needs an IT or Information Technology system or not. Even small businesses initially may do things with limited computer application in certain areas of its business, yet when it aims to make a big leap in both investment and manpower for greater production or roll out of services then it would need to have a good and efficient IT system and an equally reliable team of computer professionals.

Either the computer analyst may initiate an entirely new one or may consult with the organization’s business manager to reconfigure or overhaul the existing system. With the inputs from business analyst of the organization, the computer system analyst would prepare an estimate of cost and benefits so that the business analyst would be able to select.

In carrying out such a cost analysis the computer system analyst would also provide for cost of an older technology or the latest among the emerging systems. In this way the business analyst would be able to make a budget for the same. Further, the management of the business would be able to decide whether such costs are worth it.

Once things are finalized and approved the computer system analyst starts to design and develop by adding new configurations and functionality to the already installed computer system by choosing the right kind of hardware and software.

Overseeing and Customizing of Computer System

A computer system analyst would oversee the entire installation process of hardware and software although they may actually not develop the same on their own. All of these would be done in conjunction with the top management of the organization and would be finished during the set time frame.

The computer system analyst would involve in both cost analysis and design development and would develop the work flow chart by taking into consideration the different staff inputs at various points along the whole operation process of the organization. This would enable the organization to have better control of its operations, finance and marketing endeavors. In order to achieve this, computer systems analyst use a wide variety of techniques.

They design flow chart and diagrams beforehand so that the software technologists and programmers can trace as to how to proceed and work accordingly with their inputs. If and when a problem arises during this task then the computer system analyst helps them and guides them.

The analysts then check periodically the effectiveness of the data and information the trends in data with extensive tests. This allows them to make informed fast decision and helps them further in making the system more efficient and high performing.

General Computer System Analyst to Specialists

Most computer system installed in organizations requires only a general computer system analyst. Some analysts specialize on the basic level and may be job specific like specializing in engineering system or finance system. They do these work specific to the requirement of the organization. They may even train the IT team of the organization and help installation of IT system from A to Z. Since, they supervise such efforts they are also often called IT project managers.

There are also computer system analysts who specialize in certain level of tasks that are of great importance to an organization. For instance a system designer or architect specializes in analyzing and giving guidance to organization to choose a specific type of hardware or software system. This they do by studying the business goal of the organization and then offer solutions for the same with proper planning. They help the management in achieving short and long term objectives with the help of their specific computer system.

Then there are software quality assurance analysts that run tests on designs they had made on the organization’s computer system. They analyze the risks and mistakes and convey the same to the management and then provide solutions for the same.

Thirdly, there are programmer analysts that generally upgrade their systems and then create new applications to suit the needs of organizations. They are a little different than other analysts because they engage in a lot of coding and debugging. Specialists are often needed for businesses that are highly dependent on information technology. This is the case for most dating apps that help people find a Fuck Buddy and hook up. A dating service that isn’t reliant on an app or website might not require more than a general systems analyst.

Overall Outlook and Prospects

There is little doubt that the futures of computer system analysts are bright. Currently, the job requirements and demand in employment of these professionals far exceeds the supply of them. In fact, they are also the most sought after when compared to other jobs available in any other fields all over the world.

There will be greater reliance on part of industries foraging into health care, newer type of technological industries. In fact, the areas of cloud computing, mobile networks as well as wireless systems there are going to be phenomenal growth and therefore huge requirements for such professionals.

Not in least they are also among the highest paid professionals when compared to experts in other industries.
