Computer software has to be “loaded” into the computer storage (as memory, or RAM). 1_______. This involves passing instructions from the application software, through the system software, to the hardware which ultimately receives the instruction as a machine code. 2_______.
Sometimes data movement involves moving data between memory and registers, which enable high-speed data access in the CPU. 3_______. So, this is sometimes avoided by using “pointers” to data instead. Computations include simple operations such as incrementing the value of a variable data element. 4_______.

Computer main memory comes in two principal varieties: random access memory or RAM and read-only memory or ROM. 1_______. ROM is typically used to store the computer initial start-up instructions. 2_______. In a PC, ROM contains a specialized program called BIOS that orchestrates loading the computer operating system from the hard disk driver into RAM whenever the computer is turned on or reset. In embedded computers, which frequently do not have disk drivers, all the required software may be stored in ROM. 3_______. Flash memory blurs the distinction between ROM and RAM, as it retains its data when turned off but is also rewritable. 4_______.

Hard disks are common I/O devices used with computers.
1_______. Devices that provide input or output to the computer are called peripherals. 2_______. Hard disk drivers, floppy disk drivers and optical disk drivers serve as both input and output devices. 3_______.
Often, I/O devices are complex computers in their own right with their own CPU and memory. A graphic processing unit might contain fifty or more tiny computers that perform the calculations necessary to display 3D graphics. 4_______.

Computer systems can be discussed in two parts: hardware and software. The hardware is physical, electronic, and electro-mechanical devices. The hardware consists of Central Processing Unit (CPU), input devices and output devices. Input devices are used to provide data for the CPU. The keyboard is a common data input device. Data is sometimes entered on cards. The cards are read by an input device called a card reader. Output devices receive data from the CPU. The visual display unit (VDU) and printers are common output devices. Input devices, output devices and mass storage devices are collectively called Input-Output Devices, or peripherals. The software contains the programmes that control and coordinate the activities of the computer hardware and direct the processing of data.

A typical hardware set-up of a desktop computer consists of many components.
These components can usually be put together with little knowledge to build a computer. The motherboard is the part of a computer that connects all devices together. The memory card(s), graphic cards and processor are mounted directly onto the motherboard (the processor in a socket and the memory and graphic cards in expansion slots). The mass storage is connected to it with cables and can be installed in the computer case or in a separate case. This is the same for a keyboard and a mouse, except that they are external and they are connected to the I/O panel on the back of the computer. The monitor is also connected to the I/O panel, either through the onboard port on the motherboard, or the port on the graphic card.

CPU or Central Processing Unit is that part of a computer which executes software program instructions. In older computers this circuitry was formerly on several printed circuit boards, but in PCs it is a single integrated circuit. Nearly all PCs contain a type of CPU known as a microprocessor. The microprocessor often plugs into the motherboard using one of many different types of sockets. IBM PC compatible computers use an X86-compatible processor, usually made by Intel, AMD, VIA Technologies or Transmeta.
