4. Universal Serial Bus (USB) USB ports are developed to connect keyboard, mouse, printer and many other devices to the PC. They are developed in mid1990’s and gains a tremendous success because no additional knowledge is required to install the devices. USB ports not only communicate between devices and computer but it can also supply electric power to the devices. USB ports are not only limited to computers but it can also be seen mobile phones and video games consoles. USB ports has undergone
Universal Serial Bus (USB) is the system used for connecting peripheral devices to personal computers by means of standard connections and communication systems. It was developed during January 1996 by a cluster of companies such as the Intel, Compaq, Microsoft, Digital IBM, and Northern Telecom. These companies also formed the USB Implementation Forum Inc. (USB-IF) which is a nonprofit organization publishing the specifications of the technology and giving them support for further development and

Purchasing a Laptop (Notebook) Computer Buying a computer can be fun, expensive, and a complex process. Today’s generation, everyone wants a laptop computer with the best performance, but many will ask themselves, what about cost? How big of a screen should I get? Will it be too big or too small? How many ports do I need? What operating system do I need? Should I get a touch screen? What about internet? Do I need to buy software? When buying a laptop computer you should consider first, what am I
Introduction In this high-technology generation, information technology (IT) had become very important for every human being in this world. As information technology and information systems is very important to business too, so we have to learn IT. But, to become IT genius, we have to know how to access IT with the help of computer. After this lecture, I learn that computer is not that simple as I thought. I also learn different types of computer’s component which very important to access computer
Introduction The bus loosely defines as a digital path between resources and the processor of computer system. The bus provides an informational gateway or highway of wires, which allow binary signals to transmit to and from peripherals, memory, the central processing unit (CPU), and other components of a computer system. Due to these attributes, bus architecture divided into two major groups, frontside bus and peripheral bus. The frontside bus, also known as the system bus, facilitates all internal
Assignment Grantham University 9-9-17 A bus is a communication system that connects multiple subsystems within a computer. An average computer system normally consists of several components such as a central processing unit, memory devices, and input/output (I/O) devices. The bus system consists of linking media like wires and connectors, and a bus protocol. Buses can be categorized as serial or parallel and synchronous or asynchronous. The bus lets the different components communicate with
processor speed is 2.0 gigahertz. The processor interface has a Socket 775 design. This design makes the process of upgrading the processor more feasible. It has an Allendale processor core. The processor has a cache size of 1 MB L2. The processor’s bus speeds range from 800 megahertz to 1333 megahertz. The Intel G31 Express Northbridge chipset connects to the CPU and allows it to interface with the RAM. The Intel ICH7 Southbridge chipset is connected to the Northbridge chipset. The motherboard
BIOS stands for Basic Input Output System and is a small chip located on all motherboards. BIOS contains the information to It manages the data between the computer's operating system and attached devices such as the hard disk, keyboard , mouse , and printer . When BIOS boots up your computer, it first determines whether all of the attachments are in place and operational, then it loads the operating system into your computer's RAM from your hard disk The motherboard is the main circuit board
Unit 30 - Task 1 Hardware’s Graphics card – This is a computer hardware that makes up what you see on your monitor. It is essential that you have this hardware for the computer as it converts the data from your CPU, to a signal that makes the monitor understand what you want to see. If you were to have a really good graphics card, then the monitor will appear smoother and sharper. The images is created when the CPU receives the data from the software and then it works together with the graphics
Processor (CPU) – The processor, also known as the Central Processing Unit runs the operating system and other applications. It is constantly receiving data from the user or other active software. The data is then processed and then an output is produced which either will be displayed on screen or stored by an application. Motherboard- is the part of a computer that contains the computer’s basic circuitry and components. It allows the CPU, RAM and other components to communicate. Power Supply-
Commercialization of Personal Computers The IBM 5150, IBM’s first personal computer was introduced in a marketing campaign that led to more than 25 million Americans owning computer by 1987 (Smith and Alexander 15). IBM focused on educating consumers on how personal computers could be used to transform lives. The introduction of various applications including word processing, spreadsheet and database management facilitated information management and this led to the acceptance of personal computers
The iMac: An Apple innovation Apple was definitely “thinking different” when it created the new addition to the Macintosh family, the iMac. It’s creative design and refreshing departure from the computer industry standard of boring beige boxes is gaining this marvel many optimistic reviews. This new personal computer, which is pronounced eye-Mac –the “i” stands for Internet, combines the computer and the monitor in one unit making it, in effect, an updated version of the original one-piece Macintosh

privately listen to music in a public setting or wherever the need be. This feature also turns the phone into a mp3 player on its own, which allows one to cut out the middle man, or the need to buy a music player. Most phones have a universal charger and universal serial bus (usb) port; this excludes the whole apple line of products, which have their own port system. A memory card port satisfies many costumers. Like the other ports, it makes data transferring a lot easier. Since cam... ... middle of
homicide referred to as serial murder. This area of serial homicide specifically refers to the murder of several victims by a single person, generally unknown to the victim, over a designated period of time. Serial murder and those who commit it have always been around but have only really come to national attention in the last thirty years. Since the 1970’s people have been fascinated with and horrified by serial murderers. Despite the enormous amount of coverage of serial killers by video and print
Flash Drives and Optical Storage In Computing, optical disc drives are described by Wikipedia as a disk drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs. Some optical disc drives can only read from discs, but recent drives are able to both read and record, also called burners or writers. These drives are very commonly used in computers to read software and consumer media distributed
