The computer, including servers, is built around one or more integrated chips called The…….. . 3. A….. processor can typically process more data at the same time and can access much more memory than a 32-bit processor. 4. Making sure you have sufficient……… is one of the biggest factors in performance, even more than disk and processor.
The CPU is an electronic machine that works on a list of things to do, called 'instructions'. It reads the list of instructions, one instruction at a time, and does each one in order. To understand these instructions every programme run on the computer is converted into binary (0’s & 1’s) as this is the language that the processor understands to complete them. The speed that a CPU works at is measured in "Gigahertz", "GHz", for all modern computers. One gigahertz is one billion hertz.
The power lines in the system bus transfer power from the motherboard’s connection to the power supply to the integrated circuits (ICs or chips) and expansion boards connected to the motherboard. The control lines in the system bus controls the transmission and movement of information between devices connected to the motherboard. The address bus is used to “pick up” information from the correct memory location among the gigabytes of RAM in computer systems and “deliver” new programs and changes to the
To partition a disk using an answer file, you must add settings to the _____ configuration pass. WIN PE 7. The Windows 7 AIK tool that you use to create answer files is called _____. SIM 8. To boot from an image transmitted over the network by a WDS server, a workstation must have a network adapter that supports _____.
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.
