Computer- A computer the process-recieves in, thinks about, changes, stores, sends out, displays, and prints data in the form of bits.

1. A person wishes to purchase a personal computer for home usage. Identify the internal hardware components this computer should contain.

Mobile computing is growing at an extremely rapid rate and you can see it everywhere you go. You are probably doing it yourself multiple times a day and don’t even realize it. Phones, laptops, tablets, cloud storage and wireless networks that we use everyday are just a few elements of mobile computing.

What is a computer? There are thousands of different types of computers that are built for an extremely vast range of purposes, but overall, what do you class as a computer? Anything with a CPU?

A computer is equipment that is centralized around the CPU, microprocessor running specific instruction or application. Calculator is a program or app that can run on a computer

There are many different types and forms of computers. What we see as a fast computer for our personal use is actually nothing compared to computers used by companies to perform vast amount of data gathering and computation. The main difference between computers can be categorized into three different categories. The categories are supercomputers, main computers and personal computers.

Computer is an advanced electronic device and consist powerful components to enter data and instructions. The next is electronic device will process these data with control a set of instructions which is called program and the same time will conveys information to other people either hold the data,

1. Software – is to a computer as brain is to a human body. Hardware is functioned by the software. It collects data, organizes them and carries procedures.

Mobile computing has infiltrated every area of our planet and personal lives. We have become so dependent upon our mobile devices they are often referred to as our third limb. Regardless of race, color, creed or location, mobile technology has shrunk the entire world into the palm of our hands. Mobile technology has made research, communication with our friends and family, education, entertainment and even banking possible to do on the go.

A computer is an electronic device that stores, retrieves, and processes data, and can be programmed with instructions. A computer is composed of hardware and software, and can exist in a variety of sizes and configurations. Hardware is the physical equipment of a computer system, including the central processing unit (CPU), data-storage devices, terminals, printer, etc. Software is a program or set of instructions or rules that control the operation of a computer.

Mobile computing is technology that has enabled users to obtain internet services while being in a state of constant motion. Conventionally, internet could only be accessed only via Ethernet cable and users had to sit on one place in order to access internet. In this way, there existed no concept of taking work to a trip or connecting to world anytime. With the invention of mobile computing, users can take their work in their hands. One can now get internet service anywhere needed.
