How computers work
The fourth generation of computers
Random-access memory is a form of computer data storage. A random-access memory device allows data items to be read and written in roughly the same amount of time regardless of the order in which data items are accessed
The motherboard is a circuit board that is the foundation of a computer; it is at the bottom of the computer case. It locates power to the CPU, RAM, and all other computer hardware components and makes them communicate with one another.
input/output describes any operation, program, or device that takes data to or from a computer. Typical input/output devices are printers, hard disks, keyboards, and mouse’s. In fact, some devices are basically input-only devices (keyboards and mouse’s); others are output-only devices like printers; and others have both input and output of data (hard disks, writable CD-ROMs).
software’s is the program which the computer runs one for example HP runs on the windows software and MAC runs on the IOS software.
the four generations of computers
the computer was big and made out og vaccum tubes
2) the second generation (1959 - 1964 )
the transistor is smaller and faster and more reliable
3) the third generation
it has real time operating system and multiprogramming and database management.
4) the fourth generation (1971 - present)
contains entire central processing unit on a silicone chip
