disadvantages of computer

Computers make it extremely easy to store and access data, but their increasing use has led to an extreme level of dependence on them, which can create a number of problems if and when computers malfunction. A power outage can render entire businesses or institutions essentially inoperable without the use of computers. Data that is stored on computers can also be lost permanently if not backed up properly, and back up methods are not entirely dependable.

In a similar vein, personal data stored on computers is often extremely vulnerable to digital theft. Data regarding bank accounts, credit cards, social security numbers and more is commonly transmitted online, and security protocols to protect this data are not always effective.

Computers also create the added potential for distraction. The sheer amount of content on the Internet makes it possible to spend almost limitless time browsing blogs, playing games or chatting with friends. This can dramatically detract from productivity, whether it's at work, in school or at home. Computers can also hinder social interactions. Many users are often distracted from real life interactions by the draw of computers, diminishing social relationships.

Motherboard

Motherboard

Motherboard or system board is a main circuit board. All the computer components are plugged or connected with it.

A motherboard (sometimes alternatively known as the main board, system board, baseboard, planar board or logic board,or colloquially, a mobo) is the main printed circuit board (PCB) found in general purpose microcomputers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Unlike a back plane, a motherboard usually contains significant sub-systems such as the central processor, the chip set's input/output and memory controllers, interface connectors, and other components integrated for general purpose use.

Following ar some of the hardware components attached to the motherboard.

1. Processor
2. Input/output devices
3. Memory chips (RAM ,ROM)
4. Expansion cards
5. Expansion slots
6. Storage devices

Computer basic component

Computer basic components

               Computers are made of the following basic components.

1. Power Supply- The power supply comes with the case, but this component is mentioned separately since there are various types of power supplies. The one you should get depends on the requirements of your system. This will be discussed in more detail later
2. Motherboard- This is where the core components of your computer reside which are listed below. Also the support cards for video, sound, networking and more are mounted into this board. Microprocessor , Memory
   
   

3.

   Hard disk drive- This is where your files are permanently stored on your computer. Also, normally, your operating system is installed here.
   
   CD-ROM drive, Floppy drive
4. Monitor- This device which operates like a TV set lets the user see how the computer is responding to their commands.
5. Keyboard- This is where the user enters text commands into the computer.
6. Mouse- A point and click interface for entering commands which works well in graphical environments.

Central Processing Unit(CPU)

Central Processing Unit(CPU)

The CPU (Central Processing Unit) is the part of a  computer system that is commonly referred to as the "brains" of a computer. The CPU is also known as the processor (intel) or microprocessor (AMD). The CPU is responsible for executing a sequence of stored instructions called a program.

sample(2)

CPU is the electronic machine within a computer that carries out the instruction of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. The term has been used in the computer industry at least since the early 1960s .Traditionally, the term CPU refers to a processor, more specifically to its processing unit and control unit (CU), distinguishing these core elements of a computer from external components such as main memory and I/O circuitry
