This allowed for use of inexpensive 16K by 4-bit and certain 64K by 1-bit DRAMs. Some third-party bank-switching memory upgrades that used 256K DRAMs needed this 8-bit refresh counter to work. The Motorola 6847 is display generator capable of displaying text and graphics contained within a roughly square display matrix 256 pixels wide by 192 lines high. It can display 9 colors: black, green, yellow, blue, red, buff (almost-but-not-quite white), cyan, magenta, and orange. In alphanumeric mode, each character is a 5 dot wide by 7 dot high character in a box 8 dots wide and 12 lines high. This display mode occupies 512 bytes of memory from $400-$5FF and is a 32 character wide screen with 16 lines. The ROM character generator only holds 64 characters, so no lowercase characters are provided. On most CoCo generations it is green on very dark green. Semigraphics is a mode where alphanumerics and low resolution graphics can be mixed together.
Enter the URL of the website whose IP address you’d like to find, then press Enter. 2. The IP address lookup tool will show you the IP address of your chosen website. Is my IP address secure? Your IP address is not secure - it’s actually public information. Just as there are tools that let you find your public IP address, there are tools that let other people find your public IP address, too. Other devices on the internet use your IP address to communicate with you. Everything you do online is tagged with your IP address, including your emails, your online shopping activity, and your browsing history. Someone who knows your IP address can identify your general location, just as you can. This is how online ad tracking works: advertisers can feed you ads based on where you’re browsing from. It’s hard to associate a public IP address with a particular person, and it’s usually not worth the effort. But a motivated stalker or cybercriminal might make that effort - and so may law enforcement - which is why it’s important to know how to hide your IP.
Writing large, reliable, and readable Lisp programs requires forethought. If properly planned, the program may be much shorter than an equivalent imperative language program. Lisp is widely used in artificial intelligence. However, its usage has been accepted only because it has imperative language operations, making unintended side-effects possible. ML checks to make sure only data of the same type are compared with one another. ML is not parenthesis-eccentric like Lisp. It returns "20 : int". Like Lisp, ML is tailored to process lists. Unlike Lisp, each element is the same datatype. Moreover, ML assigns the datatype of an element at compile-time. Assigning the datatype at compile-time is called static binding. Static binding increases reliability because the compiler checks the context of variables before they are used. Prolog (1972) stands for "PROgramming in LOgic." It was designed to process natural languages. The building blocks of a Prolog program are objects and their relationships to other objects.
