What I know about early computers?
The category of early computers contains the computer systems made in the early era (i.e., the era in modern computer history defined as the period from the late 1930s to the early 1960s) utilizing mechanical, vacuum tube, discrete transistor, or other pre-integrated circuit technology.
Which is not early computer?
Right Answer is: C * The Atlas Computer was one of the world’s first supercomputers, in use from 1962 until 1971. * The LINC (Laboratory INstrument Computer) is considered as the first minicomputer and a forerunner to the personal computer.
What was the size of early computers?
It weighed more than 30 short tons (27 t), was roughly 2.4 m × 0.9 m × 30 m (8 ft × 3 ft × 98 ft) in size, occupied 167 m2 (1,800 sq ft) and consumed 150 kW of electricity. This power requirement led to the rumor that whenever the computer was switched on, lights in Philadelphia dimmed.
What is the brief history of computer?
Brief History Of Computer. The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage. He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on.
What is a brain of computer?
Central Processing Unit (CPU) The CPU is the brain of a computer, containing all the circuitry needed to process input, store data, and output results. The CPU is constantly following instructions of computer programs that tell it which data to process and how to process it.

What is the speed of computer measured in?
Clock speed is measured in units of cycles per second, which is called a Hertz (Hz). Computer boards and CPUs run at rates of millions and billions of Hertz, megahertz (MHz) and gigahertz (GHz).
Which is the main storage device of the computer?
hard disk drive
Where is data stored in a computer?
Data is stored as files – the computer equivalent of files stored in a filing cabinet. Files are stored in folders and folders are stored within drives. A storage device is a device that is capable of storing and retaining data even when the computer has been switched off. Here are some examples of storage devices.

Five common storage devices are:
- USB flash drives.
- Hard disks.
- Optical disk.
- RAM (volatile memory)
- Floppy disk.
What is difference between memory and storage?
Whereas memory refers to the location of short-term data, storage is the component within your computer that allows you to store and access data on a long-term basis. An important distinction between memory and storage is that memory clears when the computer is turned off.
