The dazzling display of this HP AIO PC touch screen laptop has 1920 x 1080 full-HD resolution that offers brightness and clarity. So, you can view photos, videos, and more in a whole new light on a vivid 27-inch diagonal display. Also, the LED-backlighting allows a thinner and more power-efficient screen, so you also get extra energy savings.
They allow users to control a computer and interact with it. They also determine the way in which users can communicate with a computer. Most popular input devices are: keyboards, mouse, digital cameras, joysticks, data suits and wired gloves. Figure 6, 7, 8 – Samples of Input Devices 2.2.3.
The PS/2 ports on the system allow for keyboaerd and mouse functionality to be availible. The optional CD-ROM and floppy disk drive aloow the user to decide how memory is used on the device. There is also a internal and external compact flash slot.
MacBook Air is powered by the 5th generation Broadwell Intel Core i5 processor which was designed to use less power and still deliver high performance. This means, not only can you do whatever you want—you can keep doing it for longer than before. In addition, the new Intel HD Graphics 6000 provides performance you 'll especially notice with games and other graphics-intensive tasks. Equipped with the lightning-fast Thunderbolt 2 port, you can connect the MacBook Air to the latest devices and displays. MacBook Air MMGF2LL/A also comes with two SuperSpeed USB 3.0 ports so you can connect the latest USB 3.0 devices as well as your other USB 2.0 devices.
Web sites use rotating banners, Flash and Shockwave animation, streaming audio and other plug-ins as dazzling effects to entice visitors. A computer memory upgrade can give your computer the zip it needs for today 's browsing. Graphic card upgrade will improve the performance of the computer as the GPU has its own CPU and on board memory, which it could improve computing experience by playing video better and freeing up memory this means that less RAM memory will be used. Graphic card it is necessary for a 32-bit system because the maximum RAM it can have is 4GB so a graphic could allow it to save more space. The last improve I am going to explain is that the hard drive upgrade, user will benefit from it by having more storage space and faster storage speed this means that more files, image and video could be store o the local hard drive.
In 4th chapter I learned about CPU and other aspects related to it such as RISC and CISC.CPU stands for central processing unit and it is very suitable name for it as it processes the instructions that it gathers from files. Following diagrams explain the basic architecture of CPU: CPU performance is given by the fundamental law: Thus, CPU performance is dependent upon Instruction Count, CPI (Cycles per instruction) and Clock cycle time. And all three are affected by the instruction set architecture. Instruction Count CPI Clock Program x Compiler x x Instruction Set Architecture x x x Microarchitecture
Some common input devices include: • Keyboard • Mouse • Touchscreen Some common output devices include: • Printer • Monitor • Projector Software Resources Software resources include all sets of information processing instructions. Software is a general term for the various kinds of programs used to operate computers and related devices. Data Resources Data resources include data and database.
The distance each ball rolled varied. Yet, even though the marble is the smallest ball, it still rolled farther than the tennis ball, golf ball, and the baseball. This is also true for the ping pong ball, except that the ping pong ball did not roll farther than the golf ball. This shows that the size of the ball does not affect how far each ball rolls. The results may have turned out the way they did because of how smooth the surface of the ball was.
For this particular task, I will be explaining what key components are necessary for client workstations to connect to a network and how to access network resources. I will be explaining the key features and functions of each of these components in relative detail. Network Devices: These are mechanisms used to connect computers and other electronic devices together so they can exchange and share files or special resources like printers or fax machines used in big organisations. LAN is the main type of network device used by the community.
Sharing Internet Access: within a computer network learners are able to access the internet at once. Speed: Using a network is a faster way for sharing and transferring files. Without a network, files are shared by replicating them to a floppy disk. Cost: Networkable versions of many popular software programmes are available at significant savings compared to buying individual licensed copies. It also allows easier upgrading of the program.
