Stack pointer<\/strong>.<\/p>\n<p>A stack pointer is a register in a computer processor that points to the top of the stack. The stack is a data structure that is used to store data temporarily. When data is pushed onto the stack, the stack pointer is decremented. When data is popped off the stack, the stack pointer is incremented.<\/p>\n<p>A register is a small amount of high-speed memory that is directly accessible by the CPU. Registers are used to store data and instructions that are currently being processed by the CPU.<\/p>\n<p>Memory is a large amount of storage that is used to store data and programs. Memory is divided into two main types: RAM (random access memory) and ROM (read-only memory). RAM is volatile memory, which means that it loses its contents when the power is turned off. ROM is non-volatile memory, which means that it retains its contents even when the power is turned off.<\/p>\n<p>An index register is a register that is used to store the address of a memory location. Index registers are often used in conjunction with arrays.<\/p>\n<p>In conclusion, the push-pop mechanism is seen in the stack pointer. The stack pointer is a register in a computer processor that points to the top of the stack. The stack is a data structure that is used to store data temporarily. When data is pushed onto the stack, the stack pointer is decremented. When data is popped off the stack, the stack pointer is incremented.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Stack pointer&#8221; option2=&#8221;Register&#8221; option3=&#8221;Memory&#8221; option4=&#8221;Index register&#8221; correct=&#8221;option1&#8243;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[686],"tags":[],"class_list":["post-19727","post","type-post","status-publish","format-standard","hentry","category-embedded-systems","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>PUSH-POP mechanism is seen in . . . . . . . .
