GUI users have windows that enable a user to view, control, and manipulate multiple things at once and is much faster to navigate when compared with a command line. Speed Command line users only need to use their keyboards to navigate a command line interface and often only need to execute a few lines to perform a task. A GUI may be easier to use because of the mouse. However, using a mouse and keyboard to navigate and control your operating system for many things is going to be much slower than someone who is working in a command line. Resources A computer that is only using the command line takes a lot less of the computers system resources than a GUI.
The benefits of relational databases far out way the disadvantages. Relational database designers waste a lot of time outlining data affiliations, only to discover that users' data conditions are constantly changing. These changes in user requirements entail revisions to the database structure and the application programs. This causes the developer to maintain applications that are rigid and don’t really meet the needs of the user. In addition, the complication of gaining access to data reduces programmer efficiency (who are then compelled to code at a low level of structural detail).
1) Which computer component is considered the nerve center of the computer system and is responsible for processing all of the data within the machine? RAM * CPU video card sound card operating system 2) What are two advantages of purchasing a preassembled computer? (Choose two.) * usually a lower cost exact components may be specified extended waiting period for assembly * adequate for performing most general applications suited for customers with special needs 3) A user plans to run multiple applications simultaneously on a computer. Which computer component is essential to accomplish this?
NT1110: Computer Structure and Logic Components of motherboards: The CPU (Central Processing Unit) component of the computer acts as the brain which is responsible for decoding, fetching and executing program instructions. The motherboard contains two major buses, the system bus and the I/O bus. These buses carry all the information between different parts of the computer. The motherboard also has memory slots which temporarily stores data when working on computers, it also increases computer’s total resources. The motherboard also has expansion slots most commonly used by audio and video cards, although the slots can be utilized by many other types of cards.
Therefore, if I don’t buy today, I might can’t get it in the future or other stores. To create the strategy to produce more and more different products to different stores, ZARA uses a lot of Information Technology (IT) to help them operate business. With those hardware or software systems, ZARA can reduce the time from design to sale. It also reduce the cost to operate the big business. However, some of the IT system like Point-of-Sale (POS) is still use MS-DOS system.
Problems like viruses, worms, and malware can seriously hurt your system performance. There are important steps that can be taken to improve your system performance in your computer. First step is to perform a routine maintenance like defragging the hard drive or cleaning it up. Hard drive checks will allow you to point out errors and uninstall unwanted programs within your system that’s preventing optimal performance. To further enhance your performance, check your hardware and software compatibility and deal with any issue that occurs.
The shared bus between the program memory and data memory leads to the Von Neumann bottleneck, the limited throughput (data transfer rate) between the CPU and memory compared to the amount of memory. Because program memory and data memory cannot be accessed at the same time, throughput is much smaller than the rate at which the CPU can work. This seriously limits the effective processing speed when the CPU is required to perform minimal processing on large amounts of data. The CPU is continually forced to wait for needed data to be transferred to or from memory. Since CPU speed and memory size have increased much faster than the throughput between them, the bottleneck has become more of a problem, a problem whose severity increases with every newer generation of CPU.
- This cannot be done at compile time because the memory allocated to a process is subject to change. 4) What are some reasons to allow two or more processes to all have access to a particular region of memory? - If a number of process are executing the same program, it is advantageous to allow each process to access the same copy of the program rather than have its own separate copy. Process that are cooperating on some task may need to share access to the same data structure. 5) In a fixed partitioning scheme, what are the advantages of using unequal size partitions?
Making sure you have sufficient……… is one of the biggest factors in performance, even more than disk and processor. 5. For the processor to communicate with the rest of the system, the processor plugs in or connects to a large circuit board called the…….. . 6. Firmware is software contained in …….
Do you think that computers and other electronic texting devices detract professionals from the regular face-time conversations? What are the likely consequences? Yes, in my personal opinion technology has definitely taken over. Besides my personal opinion, there are facts, researches and surveys that can ideally prove this. The new era of technology and its advancement have indeed removed even today’s professionals from “regular face-time conversations”.
