A computer is an electronic device, operating under the control of instructions stored in its own memory, that can accept data (input), process the data according to specified rules, produce information (output), and store the information for future use. A mobile computing device is a computing device small enough to hold in your hand. The textbook covers a lot of the general categories of computing and mobile devices. The purpose of this discussion is to talk about your favorite devices that fit into these categories

Post your three favorite computer or mobile devices and why?

The favorite computer devices are as follows:

  1. Keyboard:
    • It makes easy for us to type certain things that can be displayed on the screen and also communicate with the machines without any interrupts.
    • The keyboard also makes it very aesthetic of the computer to use and make it easy to handle so that even lame person can handle the computers.
  2. Speakers:
    • The speakers are the devices which can provide relief to the ears with good music on it whenever anyone is performing some tedious task and whatever it be people can turn up the music in order to get their mind fresh.
  3. Network Interface Controller:
    • This is the device which makes it possible for us to use the internet on various occasions without any problem and there is a very important need of the internet nowadays as computer devices are nothing without the internet.

Hence, these are my favorite computer devices.

What data do these devices usually take as input from you and what information do they usually produce for you?

  • The keyboard stores data in binary and then transfer the data from binary in which resides the key matrix process and there are certain ways of making keyboards work with particular data on it.
  • The speakers turn the electrical energy into sound energy and hence, the electrical waves are converted into the sound waves with the help of certain devices which are attached in the device.
  • The NIC receives the transmitted electromagnetic waves in order to provide connectivity to the computer or system so that the user can easily access the internet with the help of the medium such as WiFi, etc.

What is usually stored on the devices?

  • The keyboards store just the keystrokes that too for the limited number of time until and unless next keystroke is being entered. The keyboard is an input device hence, it does not store any data for a longer period of time.
  • The same applies with both the NIC as well as the speaker they are also similarly working devices just that the NIC saves the network id for further use or when the ethernet connection is being attached it remembers the connection so that it is not required to connect again and again.

Hence, these are answer to all of the stated questions.

Virtually every electronic device you buy comes with its own power adapter. The result is that these are rarely interchangeable and the one you need is the one you can’t find at the time. However, they all perform the same conceptual task. What is that and how to they do it? You may have to use some quantum physics and the Pauli Exclusion Principle.

For this assignment, you are required to write a MIPS program that reads its own instructions and counts the number of occurrences of each type of instruction (R-type, I-type, or J-type). To accomplish this task, your program should execute the following steps: First, your program should load the address of its first instruction (0x400000) into a register, and initialize three separate instruction class counters to zero. Next, your program should enter a loop that reads each instruction from memory. For...

For most of its history Microsoft has produced a computer operating system (Windows) that it sold to other firms making personal computers. While it still does this, it now produces its own line of personal computers (Winbook pro) that use the Windows operating system. Use concepts developed in class and in the book this semester to discuss factors relevant to Microsoft’s decision to vertically integrate in this way.
