What is the first computer in history?
Eniac Computer
Eniac Computer
The first substantial computer was the giant ENIAC machine by John W. Mauchly and J. Presper Eckert at the University of Pennsylvania. ENIAC (Electrical Numerical Integrator and Calculator) used a word of 10 decimal digits instead of binary ones like previous automated calculators/computers.
Is thermometer an analog computer?
A thermometer is a simple analog computer. As the temperature varies, the mercury moves correspondingly. … Although special-purpose, complex analog computers are built, almost all computers are digital. Digital methods provide programming flexibility.
What was the name of first electronic computer?
The ENIAC
The ENIAC: first general-purpose electronic computer.
Are clocks computers?
A clock is not a Computer. There is a formalism involved declaring something as Computer. Any mechanism that can compute everything such a system can compute.
Is speedometer a hybrid computer?
Answer :- Speedometer is an example of Hybrid Computers.
What type of computer is Hitachi Z800?
The Z800 was, in most ways, a minicomputer-inspired “super Z80” that would run existing, and larger, programs at considerably higher speeds.
Which is the most powerful computer?
1. Fugaku. This supercomputer, developed by Japan’s state-backed Riken research institute, is the world’s fastest for computing speed.
What is no IQ in computer?
Computers are dumb devices with zero intelligence quotient (IQ). They cannot visualize and thinking what exactly to do under a particular situation, unless they have been programmed to tackle that situation. Computers must be directed to perform each and every action.
Which is handheld computer?
A handheld computer is a computer that can conveniently be stored in a pocket (of sufficient size) and used while you’re holding it. Today’s handheld computers, which are also called personal digital assistants (PDAs), can be divided into those that accept handwriting as input and those with small keyboards.
Which computer is used in petrol pump?
A “Hybrid Computer” is used at the petrol pump.
What is Au and Lu?
Short for arithmetic logic unit, the ALU is a complex digital circuit with an AU (arithmetic unit) and a LU (logic unit). Multiple Arithmetic Logic Units are in a computer, including multiple ALU’s in the CPU (central processing unit), GPU (graphics processing unit), and FPU (floating-point unit).
Does computer have 0 IQ?
Explanation: The Computer system has no I.Q. of its own. It does only what it is programmed to do. It cannot take decisions of its own.
What was the IQ of Einstein?
It is the highest possible score for those under 18 and is higher than that of Albert Einstein, whose IQ was thought to be 160.
Is cache a memory?
cache memory, also called cache, supplementary memory system that temporarily stores frequently used instructions and data for quicker processing by the central processing unit (CPU) of a computer. The cache augments, and is an extension of, a computer’s main memory.
How is a ALU?
An arithmetic-logic unit is the part of a central processing unit that carries out arithmetic and logic operations on the operands in computer instruction words. In some processors, the ALU is divided into two units: an arithmetic unit (AU) and a logic unit (LU).
What is ALU in PLC?
An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs. In addition to ALUs, modern CPUs contain a control unit (CU).
What is a RAM in computer?
RAM stands for random-access memory, but what does that mean? Your computer RAM is essentially short term memory where data is stored as the processor needs it. This isn’t to be confused with long-term data that’s stored on your hard drive, which stays there even when your computer is turned off.
What is caching in Java?
The Java Object Cache provides caching for expensive or frequently used Java objects when the application servers use a Java program to supply their content. Cached Java objects can contain generated pages or can provide support objects within the program to assist in creating new content.
Is ROM a memory?
RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
What is full form of ROM?
Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device.
