The actual machinery - wires, transistors and circuits is called hardware; the instructions and data are called software. All general purpose computers require the following hardware components: (i) Central Processing Unit (CPU): The ‘brain’ of the computer, the component that actually executes instructions. (ii) Memory : It enables a computer to store, at least temporarily, data and programs. (iii) Input device : Usually a keyboard or mouse is used to read data and programs into the computer. (iv) Output device: A display screen, printer, etc.
The Windows 7 command-line utility that can tell you if the TCP/IP stack of another system on the network is functioning normally is called __________________. Ping.exe 7. The Windows 7 command-line utility that enables you to generate DNS request messages and then transmit them to specific DNS servers on the network is called __________________. Nslookup.exe 8. Most networks use __________________ to dynamically assign addresses and configure computers to use them.

This has led to a plethora of more or less standardized file structures for all imaginable purposes, from the simplest to the most complex. Most computer files are used by computer programs which create, modify or delete the files for their own use on an as-needed basis. The programmers who create the programs decide what files are needed, how they are to be used and (often) their names. Explain how an operating system manages multiple processes… Memory management is the function of a computer operating system responsible for managing the computer's primary memory. The memory management function keeps track of the status of each memory location, either allocated or free.
7. Drivers are programs that control a device and act as a translator between the device and the operating sustem and programs that use the device. 8. Plug and play allows you to install or connect a device, and the operating system will automatically recognize, configure, and install the appropriate drivers for the device. 9.
