what is THREAD ?

In traditional operating systems, each process has an address space and a single thread of control. In fact, that is almost the definition of a process. Nevertheless, there are frequently situations in which it is desirable to have multiple threads of control in the same address space running in quasi-parallel,...

EPROM

An EPROM, or Erasable Programmable Read-Only Memory, is a type of memory chip that retains its data when its power supply is switched off. In other words, it is non-volatile. It is an array of...

PROM

A programmable read-only memory is a form of digital memory where the setting of each bit is locked by a fuse or anti fuse. Such PROMs are used to store programs permanent...

what is ROM ?

Read-only memory is a class of storage media used in computers and other electronic devices. Because data stored in ROM cannot be modified, it is mainly used to distribute firmwa...

what is Memory Management ?

Every computer has some main memory that it uses to hold executing programs. In a very simple operating system, only one program at a time is in memory. To run a second program, the first one has to be removed and the second one placed in memory.More sophisticated operating systems allow multiple programs...

HISTORY OF OPERATING SYSTEMS

A modern computer system consists of one or more processors, some main memory, disks, printers, a keyboard, a display, network interfaces, and other input/output devices. All in all, a complex system. Writing programs that keep track of all these components and use them correctly, let alone optimally,...
