Motherboard

  • The motherboard is a large PCB board that is found in all programmable electronic devices The component attached to the board may differ from one system to another. The desktop has different types of sockets and hardware than Smartphone. CPU, memory, storage, capacitor, transistor, slots, and connectors are all common components in all electronic devices.


  • The motherboard is a thin printed circuit board (PCB) which links all different components inside your computer. So, we can say the motherboard acts as a hub in a network. People call motherboard with a different name like main board, logic board, baseboard, system board, mobo, etc. 


Parts of the Motherboard are as follow.


1. RAM Chip and RAM Slot

24. Capacitor


25. Transistor


26. VRMs


27. Mounting Screw Hole


28. Power, Reset, SW, LED Pins


RAM chip and RAM Slot


RAM is an abbreviation for Random Access Memory. It is also known as the main memory. RAM is a temporary data storage device found in computers and other electronic devices. Data stored in RAM is erased as soon as the power is turned off.


RAM supports bidirectional data transfer from the CPU to memory during a write operation and from RAM to the CPU during a read operation. It acts as a bridge between the CPU and other devices such as HDDs, CDROMs, and PEN drives.


• DRAM, SDRAM, DDR, SRAM, CMOS RAM, VRAM, and other types of RAM are available on the market. RAM in the PC market typically ranges from 2 GB to 16 GB.


CPU Chip and Socket


CPU stands for Central Processing Unit. Because the CPU performs all of the computer's decision- making tasks, it is regarded as the brain of the computer and other electronic devices. It is a large printed circuit board on which all of the components and peripherals are either directly or indirectly connected. The CPU's primaryand inputs to carry out basis


CPU consists of 3 main typical compone ALU, CU and RU:

  • ALU: Arithmetical Logical Unit (ALU) is CPU digital circuit (gates) that performs arithmetic and logical operations. ALU perfo common arithmetic operations such as addit subtraction, multiplication, and division. A performs logical operations such as the nur and letter comparisons. A single CPU may contain multiple ALUs.
  • CU: The Control Unit (CU) is a digital ci within the CPU that governs all processe enables and instructs various logical units devices, and the computer's memory on ho respond to program instructions from va components, as well as the user.
  • RU: Registers are a type of computer me used to quickly accept, store, and transfe and instructions that are being used imme by the CPU. The registers used by the C often termed as Processor registers.


Switches and Jumper

Switches and jumpers are used to reconfigure the circuit onto an existing circuit board in a reversible way.

Jumper also called Jumper Shunt is a small circuit board used to close, open or bypass part of an electronic circuit.


Closed Stage Jumper: If the plug is pushed down over two pins, the jumper is referred to as jumpered.


Opened Stage Jumper: If there is no plug into the pin then it is an open stage.

Suppose that a data warehouse for Big-University consists of the following four dimensions: student, course, semester, and instructor, and two measures count and avg_grade. When at the lowest conceptual level (e.g., for a given student, course, semester, and instructor combination), the avg_grade measure stores the actual course grade of the student. At higher conceptual levels, avg_grade stores the average grade for the given combination. a) Draw a snowflake schema diagram for the data warehouse. b) Starting with the base cuboid [student, course, semester, instructor], what specific OLAP operations (e.g., roll-up from semester to year) should one perform in order to list the average grade of CS courses for each BigUniversity student. c) If each dimension has five levels (including all), such as “student < major < status < university < all”, how many cuboids will this cube contain (including the base and apex cuboids)?

a) A Snowflake Shema is shown in figure below: b) The specific OLAP operations to be performed: 1. Roll-up on course from course_id to department. 2. Roll-up on a student from student_id to university. 3. Dice on course, student with department ="CS" and university = "biguniversity" 4. Drill-down on a student from the university to student_name. c) N = 4 dimensions The cube will contain 54 = 625 cuboids.

Suppose that a data warehouse consists of the four dimensions; date, spectator, location, and game, and the two measures, count and charge, where charge is the fee that a spectator pays when watching a game on a given date. Spectators may be students, adults, or seniors, with each category having its own charge rate. a) Draw a star schema diagram for the data b) Starting with the base cuboid [date; spectator; location; game], what specific OLAP operations should perform in order to list the total charge paid by student spectators at GM Place in 2004?

  Healthcare: ECG (Electrocardiogram) Analysis in cloud computing Healthcare is a field, subject, sector, or territory in which information technology has several uses. These apps are being used to aid businesses in supporting scientists in developing disease prevention solutions. Cloud computing has emerged as an appealing alternative for constructing health monitoring systems as a result of the development of the Internet or to put it another way, as a result of the availability of the internet. The ECG machine, for example, is a health monitoring device that measures the human body's heartbeat and prints the results on graph paper. The electrocardiogram (ECG) measures the electrical activity of the heart's Cardium. A waveform is created as a result of this action, which is repeated throughout time and symbolizes the heartbeat.  The analysis of the shape is used to identify arrhythmias, and it is the most common way of detecting heart diseases. Here the meaning of arrhythmias
