What Is X64? X64 is a generic name for the 64-bit extensions to Intel’s and AMD’s 32-bit x86 instruction set architecture (ISA). AMD introduced the first version of x64, initially called x86-64 and later renamed AMD64. Intel named their implementation IA-32e and then EMT64. There are some slight incompatibilities between the two versions, but most … Read more

What Is Subnetting? Subnetting is the technique of dividing a network into two or more smaller networks. In Subnetting we create multiple small manageable networks from a single large IP network. This increases routing, enhances the security of the network and reduces the size of the broadcast domain. Subnetting also ensures that traffic destined for … Read more

What Is Static Linking? Static linking is the process of copying all library modules used in the program into the final executable image. This is performed by the linker and is done as the last step of the compilation process. The linker combines library routines with the program code in order to resolve external references, … Read more

What Is Data Definition Language (DDL)? Data definition or data description language is a syntax used to establish and modify the structure of objects in a database by dealing by dealing with descriptions of the database schema. DDL statements are similar to a computer programming language for defining structures, especially data schemas. DDL statements create, … Read more

What Is Transmission Control Protocol (TCP)? Transmission Control Protocol (TCP) is a connection-oriented protocol that computers use to communicate over the internet. It is one of the main protocols in TCP/IP networks. TCP provides error-checking and guarantees delivery of data and that packets will be delivered in the order they were sent. TCP determines how … Read more

What Is Primary Memory? All types of computer memories that are directly accessed by the processor using data bus are referred to as Primary memory. Primary memory can also be referred to as Main memory or Internal memory, however in most cases, primary memory refers to system RAM. RAM, or random access memory, consists of … Read more

What Is Soft Hand-off? Soft handoff refers to the overlapping of repeater coverage zones, so that every cell phone set is always well within range of at least one repeater (also called a base station). In some cases, mobile sets transmit signals to, and receive signals from, more than one repeater at a time. Soft handoff technology … Read more
