Digital Computer
1. What is Digital Computer?
Write the five basic functions of computer?
Answer: Digital computer: Digital computer works on the basis of instruction composed of binary computer or Microcomputer is digital computer. We can do various works by digital computer. By the two binary numbers, 0 and 1, it can do the works of typing, for image editing, even designing of construction. In case of digital computer, we see results on the monitor screen. We can print the results by printers also. We can the data from one computer to another by writing on disk, memory device or even by internet.
Five basic functions of computer:1. Accept data by input device
2. Storage data in memory unit
3. Processing data in CPU
4. Give result by output device
5. Processing data for user instruction
2. Write the Types/Classification of Digital Computer with shortly
discuss.
Within these two categories of digital computers, a classification based on capacity and performance allows a further distinction between four types of digital computers, namely the super, mainframe, mini and Micro Computer
Micro Computer also 4 types-1. Desktopcomputer 2. Laptopcomputer 3. Palmtopcomputer 4. Notebookcomputer.
MiniComputer: - Minicomputer is more powerful then pc but its size is smaller than mainframes, used as server. Server is the computer that provides service such as printing web, file, mail etc. The computer requesting service is called client server usually is a multi-user and multi-tasking.
Main frames computer: - Larger size and more powerful then minicomputer. It has many processor and larger storage capacity. Eg>: ATM Banking system used mainframe computer.ATM Automatic Teller Machine.
Characterization and sorts of advanced PCs as per their size and utilization
As I referenced above there are 4 kinds of advanced PCs and I will show them underneath as indicated by their size beginning from the little ones so we should begin.
Microcomputers
Here's a reality, the expression "Microcomputers" is not, at this point utilized broadly as it used to be the point at which it originally came out, innovation is advancing quickly, fundamentally, any gadget that contains a microchip on a little chip was known as a microcomputer, yet it goes path past that.
This is the most popular sort of advanced PCs, you can discover it anyplace and comes in various shapes, we should find together the various kinds or instances of microcomputers.
(PC)
PCs or PCs are one illustration of microcomputers, a fundamental work station comprises of a pinnacle or case and a screen notwithstanding different peripherals like the mouse and the console.
This sort is available all over the place, homes, workplaces, organizations, banks… Etc.
Or then again some other spot or office that doesn't require colossal figuring power.
Workstations
Workstations resemble PCs, we can likewise consider them as PCs since it's normally gotten to by one individual.
Workstations are not normal for PCs, you can move them around effectively while PCs should be moved around a great deal.
Individual Digital Assistant (PDA)
These gadgets were famous in the previous century, it originally turned out during the 1980s to help financial specialists or any individual who goes to a lot of gatherings to sort out their dates, it utilizes a pen which focuses to a Touchscreen and a couple of catches or a keypad, it can associate with the web just as having some sound abilities and can likewise be utilized for correspondence.
Sounds natural? Indeed, cell phones have these capacities in addition to significantly more, that is the reason the time of PDAs was finished and got supplanted by cell phones and tablets.
Cell phones
Cell phones can be viewed as microcomputers since they use chips and have a similar capacity as a workstation if not less.
Tablets
Tablets resemble cell phones yet with a more extensive or greater touchscreen, it tends to be more valuable for perusing books like the Amazon Kindle.
Game Consoles
Game Consoles relies upon indispensable parts like a microchip and memory to run your #1 games.
In-vehicle PCs
The route framework or some other savvy electronic framework with a screen is viewed as a microcomputer.
Programmable Calculator
This kind of adding machines is more remarkable than the ordinary one, it manages weighty numerical work or tasks.
Minicomputers
Minicomputers are bigger than microcomputers (however not as extensive as Mainframe PCs), more remarkable, and more costly than a regular PC.
This kind of PC can be utilized as midrange workers or for substantial logical applications or cycles that require more force.
A Minicomputer can be gotten to by more than one client, in contrast to PCs.
Instances of Minicomputers:
A few destinations state that PDAs, tablets, journals are a portion of the instances of microcomputers, truly, I don't get it, by what method can a phone become a Minicomputer? To the extent I comprehend, the idea of Minicomputers is dealing with up to 200 clients, that is the idea of a shared worker, correct?
So we can summarize it by saying that the principal reason for utilizing Minicomputers is to make workers.
Centralized server PCs
Principally utilized for exchanges preparing, mass information handling, industry, and customer measurements… Etc.
They are additionally an incredible decision for making workers.
Virtualization
Virtualization in Mainframe PCs is the capacity to run more than one working framework simultaneously, this is an enormous efficient device obviously, this capacity requires all the more remarkable assets like all the more impressive CPU and RAM.
Instances of Mainframe PCs:
Who else other than the goliath IBM can deliver such amazing Mainframe PCs! One well-known model is the IBM Z Mainframe and IBM ES/9000.
This kind of beast PC doesn't utilize typical working frameworks like Windows, however other obscure frameworks like Linux or Z-OS.
Supercomputers
Mostly utilized for logical and designing activities, Supercomputers are so incredible thus significantly with regards to handling exceptionally confounded or substantial undertakings.
They are utilized in unmistakable circumstances or spots like foreseeing the climate or weapon advancement, and for other diversion purposes like internet games or preparing films liveliness.
Instances of Supercomputers: An illustration of a supercomputer would be cray Supercomputer and IBM Sequoia.
Super Computer: - The most powerful computer. It is also larger in size and it has larger storage capacity. There are thousands of processors (CPU) working simultaneously. It is usually for research work.Eg> CRAY I, Weather forecasting space missions, Cyber- 205 etc.
