Bezzdna [24]

Some computer engineering students decided to revise the LC-3 for their senior project.  KBSR and the DSR into one status register: the IOSR (the input/output status register). IOSR[15] is the keyboard device Ready bit and IOSR[14] is the display device Ready bit can be done in LC-3.

LC-4 is a poor design.

Explanation:

LC-3, is a type of computer educational programming language, an assembly language, which is a type of low-level programming language.

It features a relatively simple instruction set, but can be used to write moderately complex assembly programs, and is a theoretically viable target for a C compiler. The language is less complex than x86 assembly but has many features similar to those in more complex languages. These features make it useful for beginning instruction, so it is most often used to teach fundamentals of programming and computer architecture to computer science and computer engineering students.

The LC-3 specifies a word size of 16 bits for its registers and uses a 16-bit addressable memory with a 216-location address space. The register file contains eight registers, referred to by number as R0 through R7. All of the registers are general-purpose in that they may be freely used by any of the instructions that can write to the register file, but in some contexts (such as translating from C code to LC-3 assembly) some of the registers are used for special purposes.

When a character is typed:

  • Its ASCII code is placed in bits [7:0] of KBDR  (bits [15:8] are always zero)
  • The “ready bit” (KBSR[15]) is set to one
  • Keyboard is disabled -- any typed characters will be ignored

When KBDR is read:

  • KBSR[15] is set to zero
  • Keyboard is enabled
  • Alternative implementation: buffering keyboard input

Why would someone make a histogram instead of a bar chart?
Natasha_Volkova [10]

Answer:

Someone can make a histogram instead of a bar chart if distributions of variables are need to be represented and if data is quantitative.

Explanation:

Histograms are drawn to represent distributions of variables whereas bar charts are used to compare various variables. Histograms plot quantitative data whereas bar charts plot categorical data.

So, someone can make a histogram instead of a bar chart if distributions of variables are needed to be represented and if data is quantitative.

finlep [7]
#1) An important task that the operating system performs is ____, which keeps track of the files stored on a computer so that they can be retrieved when needed.
Answer: File Management System. Keeps track of where files are stored and determines how the files are stored following the operating system file allocation policies. It uses available storage space efficiently for files and creates a record/log of all file usage. It allocates a file to a user if is free, and if they are permitted access to it. Then de-allocates file when the user is finished with it.

Answer for 3.4.8 rectangle code HS
tigry1 [53]

Answer:

i think Make variables to represent the length and width of a rectangle, called length

and width

, respectively. You should set length

to 10 and width

to 5.

Then, write some mathematical expressions to computer the area and perimeter of the rectangle and save these values inside variables named area and perimeter

.Use print

statements to display the area and perimeter of the rectangle.

Your output should print the area on the first line and the perimeter on the second, like this:

50 30  Rectangle Area Formula:

Area = L * W
