Supercomputer

Disadvantages of supercomputer

There have no great difference between mainframe computers because like the mainframe it takes up a large space and cost very high. It requires trained staff to can handle and use the supercomputer and it may only be good for specific application. It is high power consumption, it use a lot of electricity, for instance, about millions Rupees in a year.
Other disadvantage is that supercomputers require massive external storage drives whose bandwidth is fast enough to accommodate the data being analyzed and produced. If storage and bandwidth can’t keep up with the data flow, the supercomputer will not be able to work at its full capacity.
Unlike ordinary desktop computers that may finish calculating a problem in a few minutes or overnight, supercomputers work on tasks that require intensive calculations which can take extremely long periods to complete. For example, a supercomputer could spend months performing calculations to support research on climate change or to help cure a disease, presenting a disadvantage to people who are in a hurry for quick results
Notebook computer
Notebook is extremely lightweight personal computer. Notebook computers typically weigh less than 6 pounds and are small enough to fit easily in a briefcase. Aside from size, the principal difference between a notebook computer and a personal computer is the display screen. Notebook computers use a variety of techniques, known as flat-panel technologies, to produce a lightweight and non-bulky display screen. The quality of notebook display screens varies considerably. In terms of computing power, modern notebook computers are nearly equivalent to personal computers. They have the same CPUs, memory capacity, and disk drives. However, all this power in a small package is expensive. Notebook computers cost about twice as much as equivalent regular-sized computers. Notebook computers come with battery packs that enable you to run them without plugging them in. However, the batteries need to be recharged every few hours.
Laptop computer
A small, portable computer small enough that it can sit on your lap. Nowadays, laptop computers are more frequently called notebook computers.
