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
Answer:
true
Explanation:
cloudware is used for many reasons and It is sometimes too much of an expense to the company
Answer:
C. <loc>
Explanation:
We need to mention the below details:
- location
- changed frequency
- last changed
- priority of page
We have the XML file for a sitemap, and we need to enter the above details for each of the Url. We need to enter the location, last changed, changed frequency and priority of the page for each of the URLs. And the URL of the home page is surrounded by the Loc tag. And hence, the correct option for this post is the C.<Loc> option.
A useful advantage of Asymmetric encryption over symmetric
encryption is that there is no secret channel necessary for the
exchange of the public key, unlike in the symmetric encryption which requires a
secret channel to send the secret key.
Another
advantage of Asymmetric encryption is that is has increased security. Asymmetric
uses two different keys (Public and private) for both encryption and decryption
of data while symmetric uses one.
