Computer hardware and software
The parts that are made of computers are made. These are called computer hardware. That means hardware quo (Electronic), f (Mechanical) Speaking to the computer, electronic, electronic, and mechanical Peripheral Devices are available. Such as keyboard, mouse, monitor, printer, motherboard, RAM, ROM, hard disk, power supply etc.
A computer has no intelligence at its own corner. Therefore, before executing any work, it is a necessary instruction Do it. This type of instruction written in the language of the computer is called ‘Gujarati’. That’s the program List of periodical directives for refreshing the work. And some of the software is flawed The aggregate sum that enables or activates the hardware to accomplish the task. This is the computer Works as an abusive environment between users and hardware. Whose corner of the computer Both hardware and software units need mutual co-operation to get output.
Computer hardware and software differences.
Based on the type of work, computer hardware can be divided into three main categories. Such as
2. Processing Device (CPU)
3. Output devise.
Computer Input Devices:
Keyboard, mouse, microphone, digital camera, card reader, joystick etc.
Computer Output Devices:
Monitor, printer, putter, speaker, disk drive, sound synthesizer, micropile, microchip etc.
Devices in the system unit:
MotherBird, Microprocessor, RAM & ROM, Hard Disk, AGP Card, LAN Card, Video Capture Card, TV card, power supply unit, CD / DVD ROM switch etc.
Work of different parts of the digital computer
CPI is the short name of the Central Processing Unit. People like brains lead man Likewise, the CPU manages the computer. Depending on the power of the CPU or the processor Computer nature and power. All the internal tasks of the computer are resolved through this processor Goes. The CPU reads the command from memory and completes the operation. Give it a Samrata or offer it For the input/ output. There are rules in the CPU that have different working hours In practice, there are mathematical reasoning parts that meet the mathematical logic operation. It also contains
2.5 processor or CPU organization.
It consists mainly of three parts
- Control parts.
- Arithmetic logic unit / mathematical reasoning part.
- Register or Memorial.
This control part by providing control over all the work done on the computer. This part is in the CPU, Regulates the data flow between the memory and input/output devices. Control single ROM and RAM To give orders to all other parts of the computer to work according to the instructions of the day. Moreover binary The code inserts memory from memory and decodes them.
Arithmetic logic unit / mathematical reasoning part
This is the part of the CPU that is executed on various types of operations such as Gig, Beta, Quality, Part, OR, AND, NOR, XOR etc. It has a program counter so that the previous There is an intake address. When an instruction will be executed, it can be read from memory in this address
Register or Memorial / Memory
Registering is a part of the CPU. All of these registrations are easy to read and read. In the mathematical argument section, These registers help the data processing. All registers at the time of completing a work in the corner Used to store data temporarily Various registrars are used for different purposes. Operation
Savings Register is a special kind of register under the ALU, which preserves the deficit and mathematical reasoning Parts used to perform the work. The results of the operation are temporarily stored here.
Program Counter is sometimes called Instruction Pointer. It’s right next to an instruction in the corner Contains the address of the order. Control a single program at the time of performing an instruction Returns the information or address of the counter information on the address bus and read this address information from Memory. After that, The number of a program counter (address) increases automatically by CPU’s internal logic.
Input / Output Register:
The result from the harmonic or accumulator is not sent directly to the output. This full temporarily The output is stored in the register and from there it is gradually sent to the output. If at If the result of the evening is over, then delay starting the next count. In the same way, the input program The inputs are stored in the registers and then sent in the evening. To make the computer work faster May Because the time the input-output operation is completed, on one hand, the computer can work on the other hand.
Memory Information Register or MIR:
Memorial Information Register to be remembered as the Memory Information Register and Memory Buffer. Main memory or Information and instructions from main memory and input register are stored in the memory information register. The address where the address or instruction from other memory registers should not be kept Remember the memory address register or MAR (Memory Address Register). Usually in computer memory Between 210 and 22 percent. So the number of MARs is 10 bits to 20 bits.
