What is a Computer?
A computer is a machine that can automatically perform arithmetical and logical sequences using computer programming. Modern computers can track widespread operation sets, called programs. These programs allow computers to carry out a vast variety of tasks.
What are the differences between hardware and software?
- Hardware is called the physical
- parts of a computer.
- Hardware you can touch, see and feel.
- Hardware is built with materials or components.
- The computer is hardware that runs under software control.
- It’s replaced with a new one if the hardware is damaged.
- Computer viruses don’t affect hardware.
- Hardware can not be electronically transferred through the network from one place to another.
- Unable for a user to make new hardware duplicates.
- The computer is called software by a set of instructions.
- The software you can’t touch or feel.
- Through writing instructions in a programming language, the software is developed.
- Computer operations are software-controlled.
- The backup copy can be reinstalled if the software is corrupt or damaged.
- Computer viruses affect software.
- The software can be electronically transmitted via the network from one place to another.
- A number of new copies of the software are available to users.
What is the connection between hardware and software?
- “Hosts” the software-hardware. The software is either loaded in the RAM or burned into a PROM (Programmable Read- Memory) on the computer to execute it. The software is then downloaded.
- Software changes the hardware status. During execution, the soft- software handles memory addresses for modifying and stored data, and accesses I / O ports (Input / Output) to perform different tasks such as open/close removable media trays, turn on / off LEDs, transmit/receive data from or to remote hardware devices and others.
