technique for constructing a processor from modules of smaller bit width. Each of these components processes one bit field or "slice" of an operand. The grouped processing components would then have the capability to process the chosen full word-length of a particular software design. Bit slice processors usually consist of an arithmetic logic unit (ALU) of 1‚ 2‚ 4 or 8 bits and control lines (including carry or overflow signals that are internal to the processor in non-bitsliced designs). For example

Machine Instructions To apply the stored-program concept‚ central processing unit (CPUs) are designed to recognize instructions encoded as bit patterns. This collection of instructions along with the encoding system is called the machine language. An instruction expressed in this language is called a machine-level instruction or‚ more commonly‚ a machine instruction. The list of machine instructions that a typical CPU must be able to decode and execute is quite short. In fact‚ once a machine

Process Control Block is the representation of each process in the operating system. It is also called a task control block. This process control block contains many pieces of information associated with a specific process. 3. Thread is a basic unit of CPU utilization; it comprises a thread ID‚ a program counter‚ a register set‚ and a stack. It shares with other threads belonging to the same process its code section‚ data section‚ and other operating-system resources‚ such as open files and signals

reduced the size and price of the computers at the same time increasing power‚ efficiency and reliability. "The Intel 4004 chip‚ developed in 1971‚ took the integrated circuit one step further by locating all the components of a computer (central processing unit‚ memory‚ and input and output controls) on a minuscule chip." Due to the reduction of cost and the availability of the computers power at a small place allowed everyday user to benefit. First came the minicomputers‚ which offered users different

What is the difference between static RAM and dynamic RAM in my computer? Your computer probably uses both static RAM and dynamic RAM at the same time‚ but it uses them for different reasons because of the cost difference between the two types. If you understand how dynamic RAM and static RAM chips work inside‚ it is easy to see why the cost difference is there‚ and you can also understand the names. Dynamic RAM is the most common type of memory in use today. Inside a dynamic RAM chip‚ each
