What is Hard Disk? It is a secondary storage device. In other word called a permanent storage device. The geometry of a hard disk drive is the organization of data on the platters. The geometry of the hard disk drive specifies how and where to store data on the surface of each platter.  It is usually specified by the following numerical values. Heads Cylinders Sectors per track Write precompensation Landing zone  Hard Disk Components Components of a Hard Disk Platters and Media Read/Write Heads Head Sliders, Arms and Actuator Spindle Motor Stepper Motor Connectors and Jumpers Logic Board Integrated Cache Platter (Tracks should be in Circle) In a platter is made up of Aluminium it only stores data. It is a light material, it has high tolerance, and shape does not change. Under the high centrifugal force that occurs at high rotation. Nowadays platter is made up of ceramic and glass, which have low thermal material. (Rotation speeds: New = 7600-10000 RPM, Old = 3600-5200RPM) Data...

What is Floppy Disk? The Floppy Disk is a simple storage disks. It was used in a med of 1970s to 1990s and perform a read and write operations through a floppy disks drive. Therefore it is thin and flexible magnetic storage tape which sealed with rectangular plastic and fabric (for removes dust particles from tape). A floppy disks is 8 inch (203 mm) and in 5 1⁄4-inch (133 mm) and 3 1⁄2 inch (90 mm) sizes.  The common capacity of a 5 1⁄4-inch floppy disks was 360 KB for Double-Sided Double Density (DSDD). In 1984, IBM introduced the PC-AT model the capacity of 1.2 MB it is a dual-sided 5 1⁄4-inch floppy disks, but it never became popular. Therefore in 1986 IBM started using 720 KB double density 3 1⁄2-inch microfloppy disk. In 1997, IBM introduced a high density of 1.44 MB with PS/2. However in 1988, IBM introduced a drive for 2.88 MB for Double-Sided Extended Density (DSED) it is PS/2 models, this was a commercial failure. The following types of a floppy disks with diagram is given...

What are the Types of RAM? The following types of RAM are given below. SRAM - Static Random Access Memory DRAM - Dynamic Random Access Memory FPM DRAM - Fast Page Mode Dynamic Random Access Memory EDO DRAM - Extended Data Out Random Access Memory SDRAM - Synchronous Dynamic Random Access Memory DDR SDRAM - Double Data Rate Synchronous Dynamic Random Access Memory RDRAM - Rambus Dynamic Random Access Memory DDR2 - Double Data Rate 2 Synchronous Dynamic Random Access Memory DDR3 - Double Data Rate 3 Synchronous Dynamic Random Access Memory DDR4 - Double Data Rate 4 Synchronous Dynamic Random Access Memory VRAM - Video Random Access Memory Random Access Memory (RAM) The Random Access Memory is a volatile memory or temporary storage device and its used to store working data and machine code and Random Access Memory allows data to read or write in the physical location of data in contact with direct access to storage media such as DVD read/write...

What is  Random Access Memory (RAM)? The Random Access Memory is a volatile memory or temporary storage device and its use to store working data and machine code and Random Access Memory allows data to read or write in the physical location of data in contact with direct access to storage media such as DVD read/write, CD read/write, and hard disk. Therefore it is a part of the computer’s main memory, which is directly accessible by CPU and it is volatile in nature, it means if the power goes off, the stored information is lost and it is used to store the data that is currently processed by the CPU and most of the programs and data that are modifiable are stores in RAM. Random Access Memory (RAM)

What are the types of Intel Processors? There are 12 types of intel processor they are Intel Atom Intel Celeron Intel Pentium Intel Core Duo Intel Core Solo Intel Core 2 Duo Intel Core 2 Quad Intel Core 2 Extreme Intel Core i3 Intel Core i5 Intel Core i7 Intel Xeon Tyes of Processors Intel Atom Intel Atom The Intel Atom processor was designed by Intel Corporation it uses less power and reduces energy consumption. It supports Ultra HD 4k multimedia and streams high frames per second (FPS). It provides high performance to users. CPU Clock Rate is 600 MHz to 2.6 GHz, Size is 45 nm to 10 nm, and Front side bus Speed is 40 MHz to 667 MHz. Intel Celeron Intel Celeron The Intel Celeron processor was designed by Intel Corporation it uses low power voltage and it is a computer microprocessor model. It used to stream, read, listen, and view the information in the computer. It supports a wide range of multimedia capabilities. CPU Clock Rate is 266 MHz to 2.6 GHz, Size is 250 nm to 14 nm, and Fron...

What is Processor? The processor is also known as the Central Processing Unit (CPU) is the integrated circuitry (IC) chip within a computer. It is responsible for the input/output, arithmetic, controlling, and logical operations which are specified by the computer commands or program. The processor is the “brain” of the PC. It carries out instructions received from software, using the data that you have inputted in order to produce output. Processor

What is Motherboard? Motherboard If the processor is the brain of the computer, the motherboard is the heart of the computer. The motherboard is the main circuit board inside the computer and however, all the components and peripherals are attached to it. Therefore the most of the compute features like scalability and upgradeability depend on the motherboard. Computer Motherboard Components Components of Motherboard Key Assessable Parameters of Motherboard Form factor Chipset CPU Memory Audio Ports and Slots Headers and Connectors BIOS Form factor The root mean square value ratio to the average value ratio of the alternating current is called Form Factor and it is the ratio of the root mean square value to the average value is also known as the absolute value of the waveform. Measurements of Form Factor, Form Factor Formula Where RMS is Root Mean Square Value, AV is Average Value Ir.m.s is the root main square value of current, therefore Iav are ...
