Processor??

The Central Processing Unit (CPU) is responsible for interpreting and executing most of the commands from the computer's hardware and software.

Also known as

processor, computer processor, microprocessor, central processor, "the brains of the computer"

Important CPU Facts:

Not all central processing units have pins on their bottom sides, but in the ones that do, the pins are easily bent. Take great care when handling, especially when installing onto the motherboard.
Each motherboard supports only a certain range of CPU types so always check with your motherboard manufacturer before making a purchase

A modern CPU is usually small and square with many short, rounded, metallic connectors on its underside. Some older CPUs have pins instead metallic connectors.
The CPU attaches directly to a CPU "socket" (or sometimes a "slot") on the motherboard. The CPU is inserted into the socket pin-side-down and a small lever helps to secure the processor.
After running even a short while, modern CPUs can get very hot. To help dissipate this heat, it is necessary to attach a heat sink and a fan directly on top of the CPU. Typically, these come bundled with a CPU purchase.
Other more advanced cooling options are also available including water cooling kits and phase change units.

Types of Computers

What are computers?

Computers are machines that perform tasks or calculations according to a set of instructions, or programs. The first fully electronic computers, introduced in the 1940s, were huge machines that required teams of people to operate. Compared to those early machines, today's computers are amazing. Not only are they thousands of times faster, they can fit on your desk, in Computers are machines that perform tasks or calculations according to a set of instructions, or programs.

calculations. Hardware items such as your monitor, keyboard, mouse, printer, and other items are often called hardware devices, or devices.

Software refers to the instructions, or programs, that tell the hardware what to do. A word processing program that you can use to write letters on your computer is a type of software. The operating system (OS) is software that manages your computer and the devices connected to it. Two well-known operating systems are Windows and Macintosh operating system. Your computer uses the Windows operating system.

 

Different kind of computers:

 

Computers range in size and capability. At one end of the scale are supercomputers, very large computers with thousands of linked microprocessors that perform extremely complex calculations. At the other end are tiny computers embedded in cars, TVs, stereo systems, calculators, and appliances. These computers are built to perform a limited number of tasks.

The personal computer, or PC, is designed to be used by one person at a time. This section describes the various kinds of personal computers: desktops, laptops, handheld computers, and Tablet PCs.

What is Memory??

Internal storage areas in the computer. The term memory identifies data storage that comes in the form of chips, and the word storage is used for memory that exists on tapes or disks. Moreover, the term memory is usually used as a shorthand for physical memory, which refers to the actual chips capable of holding data. Some computers also use virtual memory, which expands physical memory onto a hard disk.

Every computer comes with a certain amount of physical memory, usually referred to as main memory or RAM. You can think of main memory as an array of boxes, each of which can hold a single byte of information. A computer that has 1 megabyte of memory, therefore, can hold about 1 million bytes (or characters) of information

There a few types of memory examples:

RAM (random-access memory): This is the same as main memory. When used by itself, the term RAM refers to read and write memory; that is, you can both write data into RAM and read data from RAM. This is in contrast to ROM, which permits you only to read data. Most RAM is volatile, which means that it requires a steady flow of electricity to maintain its contents. As soon as the power is turned off, whatever data was in RAM is lost.

ROM (read-only memory): Computers almost always contain a small amount of read-only memory that holds instructions for starting up the computer. Unlike RAM, ROM cannot be written to.

PROM (programmable read-only memory): A PROM is a memory chip on which you can store a program. But once the PROM has been used, you cannot wipe it clean and use it to store something else. Like ROMs, PROMs are non-volatile.

EPROM (erasable programmable read-only memory): An EPROM is a special type of PROM that can be erased by exposing it to ultraviolet light.

EEPROM (electrically erasable programmable read-only memory): An EEPROM is a special type of PROM that can be erased by exposing it to an electrical charge.

Stop the Attack of Viruses in your Computer

Hello and assalamualaikum everyone, i am here to share with you guys on

how to save your computer from the vicious virus.

These are the requirements that you need to follow so that it'll safe your document and other important materials in your computer. 

Most of the tips I get it from this website here!

Hopefully you guys can take note, and fully aware of the danger that we'll face

Firstly,  install Anti Virus Software. There are many good Anti Virus programs available. For your convenience, two possible selections are listed on Useful Links. You can also check the West Coast Labs & ICSA web sites to see which Anti Virus programs have been certified. Make your choice, install it and keep it active

  Keep your Anti Virus program current. If your program is more than a year old, you may be at risk. If you install Anti Virus software but ignore it, it will quickly become obsolete. Watch for upgrades. When a newer version of your program comes out, buy it. The upgrade will intercept the newest viruses

  Between upgrades, update your Virus Definitions often. New viruses are being written every day! Therefore, Anti Virus companies are updating their virus definitions frequently. PC Technical suggests you update your virus definitions twice a week. While most Anti Virus programs will update automatically, you should check to make sure it is working properly. Automatic updates have been know to fail

 Scan your system weekly. Anti Virus software can only protect our computer systems if we use it regularly. If your program gives you a warning, let the software fix the problem. Follow up with a complete virus scan

I,me,mine..

Assalamualaikum to anyone who visiting my blog, i am sincerely welcoming all of you.

Thank you for your time for reading my small blog.

First of all, I would like to introduce myself as NAD.. yes, Nad or actual name is

I am actually the youngest between all my brothers, with my parents and the two older brother, we live happily in our home. 

My goal is to achieve what I have been dream while I am still studying in UiTM and

hopefully I will grab that opportunity- major in chemistry field.
